NOx Sensor Buying Guide & OE Cross Reference
Buying a NOx sensor well comes down to one discipline: the OE number is the specification, and price is only comparable between quotes for the same confirmed number. This guide explains how the cross-reference system in this catalogue works, using the flagship entry as the worked example, and how to read a NOx sensor price quotation against the confirmed catalogue entry. The family behind the guide holds 109 catalogued NOx entries for Scania, Iveco, Cummins, Volvo, Mercedes-Benz and other diesel applications.
The worked example: 5WK96612E

Read the cross-reference list as a set of doors into the same part: a workshop holding any one of those six OE numbers is holding a reference to this catalogue entry. That is how to search the whole family — start from whichever number is stamped on your old sensor or printed in your parts system, and confirm the entry it lands on. The specification rows matter too: a 24V truck sensor is not a substitute for a 12V application (the Volvo-catalogued 5WK97373 entry lists 12V / 24V, showing both exist in the family), and the measurement range is part of the entry's specification.
How to compare NOx sensor prices
First, confirm the number: quotes are only comparable for the same confirmed catalogue entry, for the same vehicle application. Second, compare what is inside the quote: packaging option (OEMEMBER, UAP or neutral boxes), whether a single-piece sample is available first (the company's FAQ states that a single-piece NOx sample is accepted when the item is in stock), and dispatch time — more than 100 catalogued items ship within 3 days and more than 2,700 within 15 days. Third, treat a very low price for a "compatible" sensor with no cross-reference list as what it is: an unconfirmed part.
Order by OE number, not by guesswork
This guide's ordering route is the family's: start from whichever OE number is stamped on your old sensor or printed in your parts system — 5WK96612E, 1782596, 1872080 and 5WK96751C are doors into the family's entries — and the reply confirms the entry the number lands on, with its recorded specification and application, before a comparable price exists. Quotes are only comparable for the same confirmed entry: a price for an unconfirmed 'compatible' sensor is a price for a different part. The company's FAQ states that a single-piece sample is accepted when the item is in stock, so a first order can be one unit. Numbers outside the flagship cross-reference list are checked against the family's 109 entries.
Fitment confirmation checklist
The inquiry should carry four things: the vehicle make and model, the engine type, the OE number from the old part, and any unusual connector or mounting detail. The engine matters more than it looks — one truck model can leave the factory with several engine options and several NOx sensor specifications. Confirmation rests on each entry's listed applications; if your exact model is not among them, the reply says so instead of stretching the fitment. Distributors working through a stock list can send the numbers as a spreadsheet and get a matched or not-matched answer line by line.
Packaging, stock and dispatch
NOx sensors are confirmed by engine application and position, and the packaging choice follows the buyer's channel: OEMEMBER branded boxes, UAP branded boxes, blue neutral boxes and white neutral boxes are all offered across the family. The catalogue's dispatch availability stands behind the guide's figures — more than 100 catalogued items can be dispatched within 3 days and more than 2,700 within 15 days. Warranty terms are confirmed in the quotation before payment. Certificates are available upon request. Keep the variants labelled by OE number in stock whichever box is chosen, and keep the confirmed OE list from the first order to quote back on any repeat order.
Frequently asked questions
Why do prices for 'the same' NOx sensor vary so much?
The catalogue does not record prices, and it does not tie any price to a single field. What it records is that entries sharing one generic title differ in their recorded specifications: the flagship entry lists 24V, while the 5WK97373 entry lists 12V / 24V. Two quotes under the same title are not necessarily quotes for the same entry; compare only quotes for the same confirmed OE cross-reference.
Can I buy one sample before a stock order?
The company's FAQ states that a single-piece NOx sample order is accepted when the item is in stock.
My number is not in the flagship cross-reference list. Is it covered?
Send it. The family has 109 entries; the flagship list is one entry's references, not the family's.
Send your OE number — get a quote for the confirmed part, not a lookalike.
Send the OE number, vehicle model and engine — fitment is confirmed against the catalogue entry before any quotation. Samples and mixed-OE orders are welcome.
