Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F78R7CS are qualified based on the following criteria:

Electrical Compatibility:

• Resistance value: 78.7 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Size / Dimension: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Number of Terminations: 2 (exact match required)

Acceptable Variations:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as they exceed the 0.667W requirement of the main part
• Features: Automotive AEC-Q200 certification is an additional feature that does not prevent substitution
• Packaging Format: Tape & Reel (TR) is compatible with the main part's packaging specification

All identified substitutes meet these criteria and maintain full electrical and mechanical compatibility with the RC5025F78R7CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW201078R7FKEF (Vishay Dale) and RMCF2010FT78R7 (Stackpole Electronics Inc) are both classified as Active product status, indicating ongoing manufacturing and supply availability. Both parts exceed the power rating requirement at 0.75W and include Automotive AEC-Q200 certification, providing additional application flexibility. These parts are suitable for new designs and production environments requiring long-term component availability.

Secondary Selection (Not For New Designs): The ERJ-12SF78R7U (Panasonic Electronic Components) carries a "Not For New Designs" product status classification. While electrically and mechanically compatible with the RC5025F78R7CS, this part is not recommended for new design implementations. It may be considered only for legacy system maintenance or replacement applications where existing designs already specify this component.

Compliance Considerations: All identified substitutes maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the main part. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can CRCW201078R7FKEF replace RC5025F78R7CS in existing designs?

A: Yes. The CRCW201078R7FKEF provides identical electrical specifications (78.7 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions, 2 terminations). The higher power rating (0.75W vs. 0.667W) is acceptable for direct substitution. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and substitute parts in terms of power rating?

A: The RC5025F78R7CS is rated at 0.667W (2/3W), while all substitute parts are rated at 0.75W (3/4W). The higher power rating of substitute parts does not create compatibility issues; it indicates greater thermal dissipation capability. Applications designed for 0.667W operation will function within the thermal envelope of 0.75W-rated components.

Q: Why is ERJ-12SF78R7U marked "Not For New Designs"?

A: The ERJ-12SF78R7U carries a "Not For New Designs" product status designation from Panasonic Electronic Components. This classification indicates the manufacturer is not actively promoting this part for new design implementations. While electrically and mechanically compatible, it should be reserved for legacy system support or replacement applications only.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts (CRCW201078R7FKEF, ERJ-12SF78R7U, RMCF2010FT78R7) are supplied in Tape & Reel (TR) format, which is compatible with automated assembly processes and the main part's packaging specification.

Q: Do substitute parts meet automotive qualification standards?

A: The CRCW201078R7FKEF and RMCF2010FT78R7 include Automotive AEC-Q200 certification. The ERJ-12SF78R7U also carries AEC-Q200 rating. The RC5025F78R7CS does not specify automotive qualification. Automotive-certified substitutes are acceptable for general industrial applications and provide additional qualification assurance for automotive-grade designs.

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

A: The RC5025F78R7CS has a maximum seated height of 0.026" (0.66mm), while all substitute parts have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect mechanical compatibility or board-level integration.

Q: Are all parts REACH compliant?

A: Yes. The RC5025F78R7CS and all substitute parts (CRCW201078R7FKEF, ERJ-12SF78R7U, RMCF2010FT78R7) are classified as REACH Unaffected, indicating full compliance with REACH regulatory requirements.
