Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F61R9CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 61.9 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as they exceed the original 0.667W (2/3W) specification, providing equal or superior performance capability within the same package footprint.

All identified substitute parts meet these criteria and are qualified for direct replacement in applications where the RC5025F61R9CS is specified.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW201061R9FKEF (Vishay Dale) and RMCF2010FT61R9 (Stackpole Electronics Inc) are recommended as primary substitutes. Both components maintain Active product status, ensuring long-term availability and manufacturing support. These parts feature automotive AEC-Q200 qualification, providing enhanced reliability documentation beyond the original specification. The increased power rating of 0.75W (3/4W) offers superior thermal margin compared to the 0.667W original specification while maintaining identical electrical and mechanical characteristics.

Secondary Substitute (Legacy Status):

ERJ-12SF61R9U (Panasonic Electronic Components) is classified as Not For New Designs. This part meets all electrical and mechanical substitution criteria but should be reserved for replacement applications in existing designs or where supply constraints require alternative sourcing. New design implementations should prioritize Active status components.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage protocols. No additional handling or environmental controls are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW201061R9FKEF replace RC5025F61R9CS in existing designs?

A: Yes. CRCW201061R9FKEF is electrically and mechanically equivalent. The 0.75W power rating exceeds the original 0.667W specification, providing equal or superior performance. Footprint and thermal characteristics are compatible within standard PCB assembly tolerances.

Q: What is the significance of the higher power rating in substitute parts?

A: Substitute parts rated at 0.75W (3/4W) provide additional thermal headroom compared to the original 0.667W (2/3W) specification. This allows the component to dissipate higher power levels without exceeding rated temperature limits, improving circuit reliability margins.

Q: Why is ERJ-12SF61R9U marked as "Not For New Designs"?

A: ERJ-12SF61R9U carries a legacy product status designation. While electrically and mechanically qualified for substitution, this status indicates the manufacturer is not actively promoting new design adoption. For new product development, CRCW201061R9FKEF or RMCF2010FT61R9 are preferred alternatives.

Q: Are there height differences between the main part and substitutes?

A: The original RC5025F61R9CS has a maximum seated height of 0.026" (0.66mm), while substitute parts are rated at 0.028" (0.70mm) maximum. This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect component placement or functionality.

Q: Do substitute parts require different handling or storage procedures?

A: No. All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), identical to the original component. Standard handling and storage protocols apply without modification.

Q: What is the advantage of AEC-Q200 qualification in substitute parts?

A: AEC-Q200 qualification indicates automotive-grade reliability testing and documentation. While the original RC5025F61R9CS does not carry this designation, substitute parts with AEC-Q200 qualification provide enhanced traceability and failure rate documentation suitable for applications requiring higher reliability assurance.
