Engineering Selection Recommendations
Primary Substitute: CRCW251222R1FKEG (Vishay Dale)
The CRCW251222R1FKEG is the preferred substitute for new designs and ongoing production. This part maintains active product status, identical electrical and mechanical specifications, and ROHS3 compliance. The addition of AEC-Q200 automotive qualification provides enhanced reliability documentation. Tape & Reel packaging supports high-volume manufacturing workflows. Inventory availability of 16,317 units ensures supply continuity.
Secondary Substitute: ERJ-1TNF22R1U (Panasonic Electronic Components)
The ERJ-1TNF22R1U meets all electrical and mechanical requirements with AEC-Q200 automotive qualification. However, this part carries "Not For New Designs" product status, indicating Panasonic has discontinued active development. This substitute is suitable only for legacy system maintenance, repair, or replacement applications where existing designs must be preserved. Inventory of 4,916 units is available but may decline as the product reaches end-of-life.
Selection Criteria:
- For new designs: Use CRCW251222R1FKEG
- For legacy system support: ERJ-1TNF22R1U remains functionally equivalent
- For automotive applications: Both substitutes carry AEC-Q200 certification
Frequently Asked Questions (FAQ)
Q: Can CRCW251222R1FKEG directly replace RC6432F22R1CS in existing assemblies?
A: Yes. Both parts share identical resistance (22.1 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 2512 package dimensions. Electrical and mechanical compatibility is confirmed.
Q: What is the difference between the Samsung and Vishay parts?
A: The RC6432F22R1CS emphasizes moisture resistance as a primary feature. The CRCW251222R1FKEG adds AEC-Q200 automotive qualification, indicating enhanced reliability testing and documentation. Both maintain MSL 1 (Unlimited) moisture sensitivity rating. Packaging differs: Samsung uses standard format; Vishay supplies Tape & Reel format for automated assembly.
Q: Why is ERJ-1TNF22R1U marked "Not For New Designs"?
A: This designation indicates Panasonic has transitioned this product to end-of-life status. The part remains functionally equivalent and available in inventory, but Panasonic no longer actively develops or promotes it for new applications. Use this substitute only when maintaining or repairing existing systems.
Q: Are dimensional tolerances identical across all three parts?
A: Dimensions are equivalent within manufacturing tolerances. RC6432F22R1CS: 6.30mm L × 3.20mm W, height 0.66mm max. CRCW251222R1FKEG: 6.30mm L × 3.15mm W, height 0.70mm max. ERJ-1TNF22R1U: 6.40mm L × 3.20mm W, height 0.70mm max. These variations fall within standard PCB pad design tolerances for 2512 packages.
Q: Do all three parts meet RoHS and REACH requirements?
A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected. ECCN classification is EAR99 for all parts, and HTSUS code 8533.21.0030 applies uniformly.
Q: Which substitute should be selected for high-volume production?
A: CRCW251222R1FKEG is recommended for high-volume production. Vishay supplies this part in Tape & Reel format, optimized for automated pick-and-place assembly. Inventory of 16,317 units supports sustained production runs. Active product status ensures continued availability.
Q: Can these parts be used interchangeably in automotive applications?
A: CRCW251222R1FKEG and ERJ-1TNF22R1U both carry AEC-Q200 automotive qualification. The RC6432F22R1CS does not specify automotive certification. If automotive qualification is required, use either Vishay or Panasonic substitute. For non-automotive applications, all three parts are functionally equivalent.
