Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F53R6CS is based on the following mandatory alignment criteria:

Electrical Parameters (Non-Negotiable):

• Resistance value: 53.6 Ohms (exact match required)
• Tolerance: ±1% (minimum requirement)
• Temperature coefficient: ±100ppm/°C (minimum requirement)
• Operating temperature range: -55°C ~ 155°C (minimum coverage required)

Mechanical Parameters (Non-Negotiable):

• Package / Case: 2010 (5025 Metric) (exact match required for PCB compatibility)
• Composition: Thick Film (technology type match)
• Number of terminations: 2 (standard configuration)

Regulatory & Environmental Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: MSL 1 (minimum requirement)

Power Rating Consideration: The RC5025F53R6CS is rated at 0.667W (2/3W). Substitute parts with equal or higher power ratings (0.75W or greater) are acceptable and provide enhanced thermal margin without affecting circuit function.

Product Status Consideration: Active status parts are preferred for new designs. Parts with "Not For New Designs" status may be used for replacement or legacy system support only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW201053R6FKEF (Vishay Dale)

The CRCW201053R6FKEF is the recommended substitute for the RC5025F53R6CS. This part maintains all critical electrical parameters (53.6 Ohms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and mechanical compatibility (2010 package, identical footprint). The CRCW201053R6FKEF provides enhanced power rating (0.75W versus 0.667W), offering improved thermal margin. Both parts are Active status and ROHS3 compliant with MSL 1 rating. The Vishay Dale part includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

Secondary Substitute: ERJ-12SF53R6U (Panasonic Electronic Components)

The ERJ-12SF53R6U meets all electrical and mechanical substitution criteria with identical resistance, tolerance, temperature coefficient, and operating temperature range. The 2010 package footprint is identical. This part carries AEC-Q200 automotive qualification and ROHS3 compliance with MSL 1 rating. However, the ERJ-12SF53R6U is classified as "Not For New Designs" product status. This part is suitable for replacement applications, legacy system support, or when existing inventory must be utilized, but should not be selected for new circuit designs.

Selection Logic:

For new designs requiring the RC5025F53R6CS specification, select CRCW201053R6FKEF as the primary choice due to Active product status and equivalent or superior performance characteristics.

For replacement or legacy applications where the original RC5025F53R6CS is unavailable, ERJ-12SF53R6U is electrically and mechanically compatible, though product status should be noted for design documentation.

Frequently Asked Questions (FAQ)

Q: Can CRCW201053R6FKEF directly replace RC5025F53R6CS on existing PCBs?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm). The maximum seated height difference (0.028" versus 0.026") is within typical PCB assembly tolerances and does not affect functionality or placement.

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

A: The CRCW201053R6FKEF and ERJ-12SF53R6U are rated at 0.75W (3/4W) compared to the RC5025F53R6CS at 0.667W (2/3W). A higher power rating indicates greater thermal capability and does not negatively affect circuit operation. The component will operate safely at or below the original power specification.

Q: Why is ERJ-12SF53R6U marked "Not For New Designs"?

A: "Not For New Designs" indicates that the manufacturer has discontinued active development and promotion of this part number. While the part remains electrically and mechanically compatible, it should not be selected for new circuit designs. This designation is used for replacement and legacy support only.

Q: Are all substitute parts AEC-Q200 qualified?

A: The CRCW201053R6FKEF and ERJ-12SF53R6U both carry AEC-Q200 automotive qualification. The RC5025F53R6CS does not specify automotive qualification. If automotive-grade reliability is required, the substitute parts provide this additional certification.

Q: Do all parts meet the same regulatory requirements?

A: Yes. The RC5025F53R6CS, CRCW201053R6FKEF, and ERJ-12SF53R6U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the temperature coefficient significance?

A: All three parts share ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating range. This ensures resistance value stability across the full operating temperature spectrum. Substitutes maintain identical thermal performance characteristics.

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

A: Yes, within the specified tolerance. All parts maintain ±1% tolerance, ensuring equivalent accuracy for circuit applications. The ±100ppm/°C temperature coefficient is identical across all three parts, providing consistent performance over temperature variations.
