Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2051CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 2.05 kOhms
• Tolerance: ±1%
• Power Rating: 1W
• Package Format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Termination Count: 2
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CRCW25122K05FKEG from Vishay Dale meets all substitution criteria. Both components share identical electrical specifications, package dimensions within acceptable tolerances, and equivalent environmental compliance certifications. The substitute part includes automotive-grade AEC-Q200 qualification, which represents an enhanced reliability specification beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F2051CS and CRCW25122K05FKEG are active products with ROHS3 compliance and REACH unaffected status, confirming current manufacturing availability and regulatory alignment.

The RC6432F2051CS features moisture-resistant thick film construction with MSL 1 rating. The CRCW25122K05FKEG provides equivalent moisture sensitivity classification and adds automotive-grade AEC-Q200 qualification, indicating enhanced reliability screening and qualification for automotive applications.

Dimensional variations between the two parts are minimal. The width differential of 0.002" (0.05mm) and height differential of 0.002" (0.04mm) fall within standard PCB layout tolerances for 2512 package footprints. Both components maintain identical electrical performance across the specified operating temperature range.

Selection between these parts depends on application requirements. For general industrial applications, either part provides equivalent performance. For automotive or high-reliability applications, the AEC-Q200 qualified CRCW25122K05FKEG offers additional qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can the CRCW25122K05FKEG directly replace the RC6432F2051CS on existing PCBs?

A: Yes. Both components use the 2512 (6432 Metric) package with identical footprints. The dimensional variations (0.002" width and 0.002" height differences) are within standard PCB design tolerances and do not affect placement or soldering processes.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components provide 2.05 kOhms ±1% resistance with 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Electrical performance is equivalent.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard indicating the component has undergone enhanced reliability testing and screening. This qualification is relevant for automotive applications but does not affect electrical or mechanical compatibility for non-automotive use.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC6432F2051CS and CRCW25122K05FKEG are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental regulations.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this classification, eliminating moisture-related storage constraints.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficients of ±100ppm/°C, ensuring equivalent performance in thermal cycling and high-temperature environments.
