Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F1621CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 1.62 kOhms with ±1% tolerance and temperature coefficient of ±100ppm/°C must be maintained.

Mechanical Compatibility: Package format must be 2010 (5025 Metric) with 2 terminations to ensure PCB footprint compatibility.

Environmental Compliance: RoHS3 compliance and MSL 1 rating are required for equivalent substitution.

Power Rating Consideration: Substitute parts may have equal or higher power ratings (0.667W or greater) without affecting circuit performance, as long as thermal management and board layout remain unchanged.

Composition: Thick film construction is maintained across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

CRCW20101K62FKEF (Vishay Dale): This substitute maintains all electrical and mechanical specifications with Active product status. The 0.75W power rating provides increased thermal margin compared to the 0.667W main part. Automotive AEC-Q200 qualification is included. This part is suitable for direct substitution in new designs and production environments.

ERJ-12SF1621U (Panasonic Electronic Components): This substitute meets all electrical and mechanical requirements with equivalent 0.75W power rating and AEC-Q200 automotive qualification. However, product status is classified as Not For New Designs. This part is available for legacy system support and field replacement applications only, and should not be selected for new circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K62FKEF replace RC5025F1621CS in new designs?

A: Yes. CRCW20101K62FKEF maintains identical resistance (1.62 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), package format (2010), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W vs 0.667W) is compatible. Active product status supports new design implementation.

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

A: RC5025F1621CS has a maximum seated height of 0.026" (0.66mm), while both CRCW20101K62FKEF and ERJ-12SF1621U have maximum seated heights of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect footprint compatibility.

Q: Why is ERJ-12SF1621U marked as Not For New Designs?

A: ERJ-12SF1621U carries a Not For New Designs product status designation. This part remains available for existing system support and field replacement scenarios but should not be selected for new circuit development or production programs.

Q: Are all substitutes RoHS3 compliant?

A: Yes. RC5025F1621CS, CRCW20101K62FKEF, and ERJ-12SF1621U are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available for these parts?

A: RC5025F1621CS is supplied in standard packaging. CRCW20101K62FKEF and ERJ-12SF1621U are supplied in Tape & Reel (TR) format for automated assembly processes.
