Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F4023CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 402 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All substitute parts listed maintain these electrical and mechanical specifications. Dimensional variations within supplier tolerances do not affect functional equivalence. Substitute parts are grouped by product status and additional certifications (automotive AEC-Q200) where applicable.

Parameter Comparison

Engineering Selection Recommendations

For General Industrial Applications: The RC6432F4023CS (Samsung Electro-Mechanics) is the primary selection. All three substitute parts are electrically and mechanically equivalent and may be used interchangeably based on availability.

For Automotive Applications Requiring AEC-Q200 Certification: Select AC2512FK-07402KL (YAGEO) or CRCW2512402KFKEG (Vishay Dale). Both parts maintain Active product status and provide automotive-grade qualification. The RC6432F4023CS does not carry AEC-Q200 certification and is not suitable for automotive designs requiring this standard.

For Legacy Design Continuation: ERJ-1TNF4023U (Panasonic Electronic Components) is electrically equivalent but carries "Not For New Designs" product status. This part is suitable only for sustaining existing production or repair applications. New designs should not incorporate this part number.

Inventory and Supply Considerations: Current stock levels are: RC6432F4023CS (822 Pcs), AC2512FK-07402KL (2268 Pcs), CRCW2512402KFKEG (4453 Pcs), ERJ-1TNF4023U (5267 Pcs). Selection may be influenced by procurement lead times and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07402KL replace RC6432F4023CS in non-automotive applications?

A: Yes. AC2512FK-07402KL is electrically and mechanically equivalent to RC6432F4023CS. The additional AEC-Q200 automotive certification does not restrict use in general industrial applications. Both parts share identical resistance, tolerance, power rating, package type, and operating temperature specifications.

Q: What is the difference between RC6432F4023CS and ERJ-1TNF4023U?

A: Both parts are electrically equivalent with identical resistance, tolerance, power rating, and package specifications. The primary difference is product status: RC6432F4023CS is Active, while ERJ-1TNF4023U is classified as "Not For New Designs." ERJ-1TNF4023U should be used only for sustaining existing production or repair applications.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within supplier tolerances. RC6432F4023CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. AC2512FK-07402KL measures 0.250" L x 0.122" W (6.35mm x 3.10mm) with 0.026" max height. CRCW2512402KFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max height. ERJ-1TNF4023U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.028" max height. These variations are within standard PCB footprint tolerances for 2512 package components and do not affect functional compatibility.

Q: Which substitute part has the best availability?

A: CRCW2512402KFKEG (Vishay Dale) currently has the highest inventory at 4453 pieces. This part is Active status and AEC-Q200 certified, making it suitable for both general industrial and automotive applications.

Q: Can I use CRCW2512402KFKEG in automotive designs?

A: Yes. CRCW2512402KFKEG carries AEC-Q200 automotive certification and is classified as Active product status. It meets all electrical and mechanical requirements for automotive applications requiring 402 kOhms ±1% 1W thick film chip resistors in 2512 package.

Q: Is the RC6432F4023CS suitable for automotive applications?

A: RC6432F4023CS does not carry AEC-Q200 automotive certification. For automotive designs, use AC2512FK-07402KL, CRCW2512402KFKEG, or ERJ-1TNF4023U instead.

Q: What does "Not For New Designs" mean for ERJ-1TNF4023U?

A: This designation indicates the part is in mature or end-of-life phase. Panasonic does not recommend this part for new product designs. It remains available for sustaining existing production runs and repair applications. New designs should select RC6432F4023CS, AC2512FK-07402KL, or CRCW2512402KFKEG.
