Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1623CS are qualified based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 162 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

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

Compliance & Environmental (Must Match or Exceed):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH status: REACH Unaffected

Two substitute parts meet these criteria: CRCW2512162KFKEG (Vishay Dale) and ERJ-1TNF1623U (Panasonic Electronic Components). Both maintain identical electrical and mechanical specifications while offering automotive-grade AEC-Q200 qualification, which exceeds the base requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512162KFKEG (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains active product status, carries AEC-Q200 automotive qualification, and is available in higher inventory (2771 units). The Vishay component is suitable for both commercial and automotive-grade circuit implementations.

ERJ-1TNF1623U (Panasonic Electronic Components) qualifies as a functional equivalent but carries "Not For New Designs" status. While electrically and mechanically identical with AEC-Q200 qualification, this part should be reserved for legacy system maintenance, repair, or replacement scenarios where existing designs already specify the Panasonic component. New circuit designs should prioritize CRCW2512162KFKEG or the original RC6432F1623CS.

RC6432F1623CS (Samsung Electro-Mechanics) remains the original specification. Selection between the original and CRCW2512162KFKEG depends on supply chain availability, cost considerations, and whether automotive-grade qualification is required for the application.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512162KFKEG directly replace RC6432F1623CS in existing designs?

A: Yes. Both components share identical electrical specifications (162 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), mechanical package (2512/6432 Metric), and compliance certifications (ROHS3, MSL 1). The Vishay part includes additional AEC-Q200 automotive qualification, which does not create incompatibility. Direct substitution is electrically and mechanically valid.

Q: What is the difference between the Samsung and Vishay parts?

A: The RC6432F1623CS features moisture-resistant thick film construction. The CRCW2512162KFKEG adds automotive AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive environments. Both use identical thick film composition and operate within the same temperature and electrical parameters. The Vishay part represents a superset of the Samsung part's capabilities.

Q: Why is ERJ-1TNF1623U marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While the component remains functionally equivalent and available in inventory (1643 units), it should not be selected for new circuit designs. The part is suitable only for maintaining or repairing existing systems that already incorporate this component.

Q: Are there dimensional differences between these three parts?

A: Minor dimensional variations exist within acceptable tolerances. The RC6432F1623CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" max height. The CRCW2512162KFKEG measures 0.248" L × 0.124" W (6.30mm × 3.15mm) with 0.028" max height. The ERJ-1TNF1623U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" max height. These variations fall within standard PCB footprint tolerances for 2512 packages and do not affect interchangeability.

Q: What packaging formats are available?

A: The RC6432F1623CS is supplied in standard packaging (format not specified). CRCW2512162KFKEG and ERJ-1TNF1623U are both available in Tape & Reel (TR) format, which is standard for automated assembly processes. Confirm packaging requirements with your procurement specification before ordering.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC6432F1623CS, CRCW2512162KFKEG, and ERJ-1TNF1623U are all ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level). All three parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8533.21.0030.
