Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F36R5CS are qualified based on the following criteria:

Electrical Equivalence:

• Identical resistance value: 36.5 Ohms
• Identical tolerance: ±1%
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C

Mechanical Compatibility:

• Identical package designation: 2010 (5025 Metric)
• Identical composition: Thick Film
• Identical number of terminations: 2
• Compatible physical dimensions and height specifications

Regulatory & Compliance Alignment:

• ROHS3 Compliant status maintained
• Moisture Sensitivity Level 1 (Unlimited) maintained
• REACH Unaffected status maintained

Power Rating Consideration: Substitute parts rated at 0.75W (3/4W) exceed the original 0.667W (2/3W) specification and are electrically compatible for applications where the original power rating is sufficient. Higher power ratings provide design margin without affecting electrical performance at the specified operating point.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW201036R5FKEF (Vishay Dale)

The CRCW201036R5FKEF is the preferred substitute for the RC5025F36R5CS. Both components maintain Active product status, ensuring continued availability and manufacturing support. The Vishay Dale part carries AEC-Q200 automotive qualification, providing additional reliability assurance. The 0.75W power rating exceeds the original specification, offering design margin. All electrical parameters, package dimensions, and regulatory compliance requirements are met. This part is suitable for new designs and production applications.

Secondary Substitute: ERJ-12SF36R5U (Panasonic Electronic Components)

The ERJ-12SF36R5U meets all electrical and mechanical compatibility requirements. However, this part carries a "Not For New Designs" product status designation, indicating that Panasonic has discontinued active development and support for this component. While existing inventory is available (6600 Pcs), this part should be reserved for legacy system maintenance, repair, or applications where design freeze conditions apply. New design implementations should prioritize the CRCW201036R5FKEF.

Compliance & Certification:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can CRCW201036R5FKEF replace RC5025F36R5CS in existing designs?

A: Yes. The CRCW201036R5FKEF is electrically and mechanically equivalent. Both components share identical resistance (36.5 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2010 package designation. The higher power rating (0.75W vs. 0.667W) is compatible with applications designed for the original part.

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

A: The seated height differs slightly. RC5025F36R5CS has a maximum seated height of 0.026" (0.66mm), while both CRCW201036R5FKEF and ERJ-12SF36R5U have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect mechanical compatibility in standard applications.

Q: Why is ERJ-12SF36R5U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has transitioned this product to end-of-life status. While current inventory exists, the manufacturer no longer actively supports or develops this component. For new product designs, CRCW201036R5FKEF is the recommended choice to ensure long-term supply chain stability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC5025F36R5CS, CRCW201036R5FKEF, and ERJ-12SF36R5U are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What does the ±100ppm/°C temperature coefficient mean for substitution?

A: The temperature coefficient specifies the resistance change per degree Celsius. All three parts share identical ±100ppm/°C specifications, ensuring equivalent thermal stability across the -55°C ~ 155°C operating range. This parameter is critical for precision applications and confirms full substitution compatibility.

Q: Can I use a 0.75W rated resistor in place of a 0.667W rated resistor?

A: Yes. A higher power rating indicates greater thermal dissipation capability. If your circuit design requires only 0.667W, using a 0.75W component provides additional thermal margin without affecting electrical performance. The component will operate within safe limits at the lower power requirement.
