Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F4873CS are identified based on the following critical parameters that determine functional interchangeability:

Electrical Specifications: Resistance value (487 kOhms) and tolerance (±1%) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) must be identical or superior.

Package Compatibility: The 2010 (5025 Metric) package format is mandatory. Physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) must align with PCB layout requirements.

Power Rating Consideration: The substitute part power rating may equal or exceed the original specification (0.667W minimum). Higher power ratings provide design margin without affecting circuit function.

Composition & Construction: Thick film construction is required to maintain electrical performance characteristics and temperature stability.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are standard requirements for modern electronic applications.

The CRCW2010487KFKEF from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC5025F4873CS (Samsung Electro-Mechanics) is the original specified component with Active product status and full ROHS3 compliance. Current inventory of 951 pieces supports immediate procurement.

Substitute Selection: CRCW2010487KFKEF (Vishay Dale) is a qualified substitute with Active product status and ROHS3 compliance. This part provides a 0.083W power rating increase (0.75W vs. 0.667W), offering additional thermal margin in the application. The substitute includes AEC-Q200 automotive qualification, which exceeds standard industrial requirements. Inventory availability of 2114 pieces supports high-volume applications. Maximum seated height increases by 0.002" (0.04mm), which remains within typical PCB assembly tolerances for 2010 package components.

Both parts are suitable for direct substitution based on matching electrical specifications, identical package dimensions, and equivalent environmental compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010487KFKEF replace RC5025F4873CS in existing designs?

A: Yes. Both parts share identical resistance value (487 kOhms), tolerance (±1%), package format (2010 / 5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute's higher power rating (0.75W vs. 0.667W) and AEC-Q200 qualification provide additional design margin without affecting circuit performance.

Q: What is the significance of the power rating difference?

A: The CRCW2010487KFKEF is rated for 0.75W compared to the RC5025F4873CS at 0.667W. This 0.083W increase allows the substitute to dissipate more heat under identical operating conditions, reducing junction temperature and extending component life. Applications requiring the full 0.667W specification can safely use the higher-rated substitute.

Q: Are there package compatibility concerns?

A: No. Both parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Maximum seated height differs by 0.002" (0.04mm), which is negligible for standard PCB assembly processes and does not affect placement or soldering.

Q: Do both parts meet current compliance requirements?

A: Yes. Both RC5025F4873CS and CRCW2010487KFKEF are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are classified as Active products with current manufacturing support.

Q: What is the basis for substitution eligibility?

A: Substitution is based on matching electrical specifications (resistance, tolerance, temperature coefficient), identical package dimensions, equivalent thermal operating range, and compliance certifications. The CRCW2010487KFKEF meets all these criteria and is therefore a qualified substitute.
