Substitute Part Grouping Explanation

Substitute parts for the RC6432F4223CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 422 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core parameters. Variations in physical dimensions (length, width, height) within standard tolerances and differences in product status or packaging format do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512422KFKEG (Vishay Dale) is the primary substitute for new designs. This part maintains active production status and meets all electrical and mechanical specifications. The CRCW series includes automotive AEC-Q200 qualification, providing additional reliability assurance for demanding applications. Packaging is supplied in Tape & Reel format.

ERJ-1TNF4223U (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" product status. This part is suitable for replacement or repair of existing assemblies where the original RC6432F4223CS is unavailable. The ERJ-1TN series also includes AEC-Q200 automotive qualification. Use of this part in new designs is not recommended due to its discontinued status.

Both substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512422KFKEG be used as a direct replacement for RC6432F4223CS?

A: Yes. Both parts share identical electrical specifications (422 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and package type (2512/6432 Metric). Physical dimensions vary within standard tolerances. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and its substitutes?

A: The RC6432F4223CS features moisture-resistant construction. The CRCW2512422KFKEG and ERJ-1TNF4223U include automotive AEC-Q200 qualification. All three parts meet the same core electrical and mechanical requirements. Dimensional variations are minor and do not affect PCB layout compatibility for standard 2512 footprints.

Q: Why is ERJ-1TNF4223U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status. While functionally equivalent and currently in stock, Panasonic has discontinued this product line. For new circuit designs, CRCW2512422KFKEG is the recommended substitute.

Q: Are there packaging format differences between these parts?

A: The RC6432F4223CS is supplied in standard packaging. CRCW2512422KFKEG and ERJ-1TNF4223U are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing processes.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW2512422KFKEG and ERJ-1TNF4223U both carry AEC-Q200 automotive qualification. The RC6432F4223CS does not list this certification. For automotive applications, CRCW2512422KFKEG is the appropriate choice.
