RC5025F2053CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2053CS is a 205 kOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package type, dimensions, termination count) while maintaining compliance with applicable standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2053CS are qualified based on the following criteria:

Electrical Compatibility:

• Resistance value: 205 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Compatibility:

• Package type: 2010 (5025 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Regulatory & Environmental:

• RoHS3 Compliance (required)
• Moisture Sensitivity Level 1 (required)

The identified substitute parts meet all electrical and mechanical parameters. Differences in power rating (0.75W vs. 0.667W) and specific feature sets (Automotive AEC-Q200 certification) represent enhancements or specialized qualifications that do not prevent substitution in applications designed for the base specifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010205KFKEF (Vishay Dale) is the primary substitute option. This part maintains Active product status, meets all electrical and mechanical specifications, and carries AEC-Q200 automotive qualification. The increased power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance in applications designed for the base 205 kOhm ±1% specification.

ERJ-12SF2053U (Panasonic Electronic Components) is a secondary substitute option. While this part meets all electrical and mechanical parameters and carries AEC-Q200 qualification, it is designated as "Not For New Designs." This classification restricts its use to legacy system support, field replacements, or applications where existing supply chains are established. New design implementations should prioritize the Vishay Dale CRCW2010205KFKEF alternative.

Both substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010205KFKEF replace RC5025F2053CS in all applications?

A: Yes. The CRCW2010205KFKEF matches all critical electrical parameters (205 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical specifications (2010 package, 2 terminations, thick film composition). The higher power rating (0.75W vs. 0.667W) is a non-limiting enhancement.

Q: Why is ERJ-12SF2053U marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Panasonic has discontinued active development and promotion of this part number. While the part remains functionally equivalent and available in inventory, new circuit designs should specify CRCW2010205KFKEF to ensure long-term supply continuity and manufacturer support.

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

A: Yes. The RC5025F2053CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is negligible for standard PCB assembly and does not affect electrical performance or mechanical fit in typical applications.

Q: Do all parts meet the same compliance standards?

A: Yes. The RC5025F2053CS, CRCW2010205KFKEF, and ERJ-12SF2053U are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both substitute parts additionally carry AEC-Q200 automotive qualification, which exceeds the base specification.

Q: What is the difference between 2/3W and 3/4W power ratings?

A: The RC5025F2053CS is rated at 0.667W (2/3W), while the substitute parts are rated at 0.75W (3/4W). In circuit applications, the substitute parts can dissipate up to 12.5% more power without exceeding rated limits. This provides additional thermal headroom and does not create compatibility issues in designs specified for the lower power rating.
