RC5025F56R2CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F56R2CS is a 56.2 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, and power rating), mechanical compatibility (package dimensions and termination count), and environmental performance characteristics. While the RC5025F56R2CS remains in active production, substitute options provide alternative sourcing channels, enhanced power ratings, or automotive-grade certifications for applications requiring higher reliability standards.

Substitute Part Grouping Explanation

Substitution logic for the RC5025F56R2CS is based on the following criteria:

Electrical Compatibility: All substitute parts maintain the identical 56.2 Ohm resistance value and ±1% tolerance specification. This ensures direct functional equivalence in circuit applications without requiring design modifications.

Mechanical Compatibility: All substitute parts utilize the 2010 (5025 Metric) package format with identical footprint dimensions (0.197" L × 0.098" W / 5.00mm × 2.50mm) and two-terminal configuration. Maximum seated heights range from 0.026" to 0.028", ensuring compatibility with standard PCB assembly processes and clearance requirements.

Thermal Performance: Substitute parts are rated for 0.75W (3/4W) power dissipation, which exceeds the original 0.667W specification. This provides enhanced thermal margin and allows operation in higher-power applications without derating.

Environmental Specifications: All substitute parts maintain the -55°C to 155°C operating temperature range, ±100ppm/°C temperature coefficient, MSL 1 rating, and ROHS3 compliance. These parameters ensure equivalent environmental performance and regulatory compliance.

Automotive Certification: Four of the five substitute parts carry AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade component specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F56R2CS): Maintain use of the original Samsung Electro-Mechanics RC5025F56R2CS for applications where the 0.667W power rating is sufficient and standard industrial-grade specifications meet design requirements. This part maintains Active product status with established supply channels and full RoHS3 compliance.

Upgrade Path (AC2010FK-0756R2L, CRCW201056R2FKEF, RMCF2010FT56R2): Select YAGEO AC2010FK-0756R2L, Vishay Dale CRCW201056R2FKEF, or Stackpole Electronics RMCF2010FT56R2 for applications requiring enhanced thermal performance (0.75W rating), automotive-grade AEC-Q200 certification, or alternative sourcing. All three parts maintain Active product status and provide identical electrical and mechanical compatibility with superior power handling capability.

Legacy Consideration (ERJ-12SF56R2U): The Panasonic Electronic Components ERJ-12SF56R2U is classified as "Not For New Designs" and should not be selected for new product development. This part remains available for legacy system support and repair applications only.

Compliance Verification: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature specifications (-55°C to 155°C). No additional compliance verification is required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the RC5025F56R2CS be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical resistance (56.2 Ohms), tolerance (±1%), package format (2010 / 5025 Metric), and environmental specifications. Direct PCB-level substitution is supported without circuit design modifications. The substitute parts offer equal or superior power ratings (0.75W vs. 0.667W).

Q: What is the primary difference between the RC5025F56R2CS and its substitutes?

A: The main difference is power rating and automotive certification. The RC5025F56R2CS is rated for 0.667W (2/3W) without automotive qualification. Four of the five substitute parts are rated for 0.75W (3/4W) and carry AEC-Q200 automotive certification, providing enhanced thermal margin and reliability documentation for automotive applications.

Q: Are there any height or footprint differences that could affect PCB assembly?

A: Maximum seated heights vary slightly: RC5025F56R2CS at 0.026" (0.66mm), AC2010FK-0756R2L at 0.026" (0.65mm), and the remaining substitutes at 0.028" (0.70mm). These variations are within standard PCB assembly tolerances and do not affect component placement or clearance in typical applications. Footprint dimensions remain identical across all parts (0.197" L × 0.098" W).

Q: Should the ERJ-12SF56R2U be used for new designs?

A: No. The ERJ-12SF56R2U carries a "Not For New Designs" product status designation. This part should be reserved for legacy system support and repair applications only. For new product development, select from the Active-status alternatives: AC2010FK-0756R2L, CRCW201056R2FKEF, or RMCF2010FT56R2.

Q: Do all substitute parts meet the same environmental and compliance requirements?

A: Yes. All substitute parts maintain identical operating temperature range (-55°C to 155°C), temperature coefficient (±100ppm/°C), MSL 1 rating, and ROHS3 compliance. Environmental and regulatory performance is equivalent across all options.

Q: Which substitute part offers the best availability?

A: Based on provided inventory data, Panasonic ERJ-12SF56R2U shows the highest stock level at 12,376 pieces, followed by Vishay Dale CRCW201056R2FKEF at 8,598 pieces. However, ERJ-12SF56R2U is not recommended for new designs. Among Active-status parts, CRCW201056R2FKEF offers the highest inventory availability.

Q: Can substitute parts with higher power ratings (0.75W) be used in applications designed for 0.667W?

A: Yes. Higher power ratings provide additional thermal margin and are fully compatible with applications designed for lower power specifications. No circuit modifications are required. The 0.75W-rated substitutes will operate safely in any application previously using the 0.667W RC5025F56R2CS.
