RC5025F3573CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3573CS is a 357 kOhms ±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) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and resistance value, allowing for direct board-level replacement in applications where the primary part becomes unavailable or when design requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3573CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 357 kOhms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Package / Case: 2010 (5025 Metric) (identical footprint required)
• Composition: Thick Film (same technology type)
• Temperature Coefficient: ±100ppm/°C (equal or better stability)
• Operating Temperature Range: -55°C to 155°C (minimum coverage required)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Flexible Parameters:

• Power Rating: Minimum 0.667W; higher ratings (0.75W, 1W, etc.) are acceptable as they provide additional thermal margin
• MSL Rating: Must be MSL 1 or equivalent; higher MSL classes acceptable
• Packaging Format: Tape & Reel (TR) or bulk packaging acceptable for equivalent electrical performance

The RMCF2010FT357K from Stackpole Electronics Inc qualifies as a direct substitute based on matching all mandatory parameters while providing an increased power rating of 0.75W (3/4W), which exceeds the minimum requirement.

Engineering Selection Recommendations

Primary Part: RC5025F3573CS (Samsung Electro-Mechanics)

Selection criteria: Use when Samsung sourcing is specified, when existing inventory supports supply chain continuity, or when the 0.667W power rating is the design-limiting specification.

Substitute Part: RMCF2010FT357K (Stackpole Electronics Inc)

Selection criteria: Use when Samsung supply is unavailable, when higher power margin is beneficial for thermal design, or when AEC-Q200 automotive qualification is required for application compliance. The increased power rating of 0.75W provides additional thermal headroom without affecting circuit performance. Both parts maintain identical electrical characteristics, package footprint, and regulatory compliance status.

Both parts are Active products with established supply availability. The RMCF2010FT357K carries AEC-Q200 automotive qualification, which may be advantageous for applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT357K replace RC5025F3573CS directly on the PCB?

A: Yes. Both components share identical 2010 (5025 Metric) package footprints with matching length and width dimensions (5.00mm x 2.50mm). The maximum seated height difference (0.66mm vs 0.70mm) is negligible and does not impact PCB assembly or clearance requirements.

Q: Does the higher power rating of RMCF2010FT357K (0.75W vs 0.667W) affect circuit operation?

A: No. Power rating indicates thermal capability, not electrical output. A higher-rated component provides additional thermal margin and does not alter resistance value, tolerance, or frequency response. The circuit will function identically.

Q: Are both parts compliant with RoHS and REACH regulations?

A: Yes. Both RC5025F3573CS and RMCF2010FT357K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification indicates that the resistance value will drift by a maximum of 100 parts per million for each degree Celsius change in operating temperature. Both parts maintain identical temperature stability across the -55°C to 155°C operating range, ensuring consistent circuit performance across environmental conditions.

Q: Does MSL 1 (Unlimited) rating affect storage or handling procedures?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. Both parts can be stored and handled without special moisture control measures, desiccant requirements, or bake-out procedures prior to assembly.

Q: Is the AEC-Q200 qualification on RMCF2010FT357K relevant for non-automotive applications?

A: AEC-Q200 is an automotive industry qualification standard. For non-automotive applications, this certification is not required but does not negatively impact performance. Both parts are suitable for general industrial, consumer, and commercial applications.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Yes, provided the design does not specifically require Samsung sourcing or exclude Stackpole components. The electrical and mechanical parameters are equivalent, and both parts meet identical compliance standards. No circuit re-analysis is required for substitution.
