RC5025F4751CS Equivalent & Substitute Parts

Part Overview

The RC5025F4751CS is a 4.75 kOhm ±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 features moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part maintains Active product status and holds ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value and tolerance), mechanical compatibility (package dimensions and form factor), and thermal characteristics. Substitute components with higher power ratings or automotive-grade certifications provide enhanced performance margins for demanding applications while maintaining functional interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F4751CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 4.75 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistance: Required
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts with equal or higher power ratings (0.75W or greater) are functionally equivalent and provide improved thermal performance margins.

All identified substitute parts meet these criteria. The three substitute components (RC2010FK-074K75L, CRCW20104K75FKEF, and RMCF2010FT4K75) maintain identical electrical and mechanical specifications while offering increased power dissipation capacity at 0.75W (3/4W). Two substitutes include automotive AEC-Q200 certification, providing additional qualification for demanding environments.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RC5025F4751CS and maintain Active product status with full ROHS3 compliance and MSL 1 ratings.

RC2010FK-074K75L (YAGEO): This substitute provides direct electrical and mechanical equivalence with a 0.75W power rating increase. The part is packaged in Tape & Reel format and maintains all core specifications of the original component. Selection is appropriate for standard industrial applications requiring moisture-resistant thick film construction.

CRCW20104K75FKEF (Vishay Dale): This substitute incorporates AEC-Q200 automotive qualification in addition to the base electrical specifications. The 0.75W power rating and identical package dimensions ensure mechanical and thermal compatibility. Selection is appropriate for automotive applications or environments requiring automotive-grade component certification.

RMCF2010FT4K75 (Stackpole Electronics Inc): This substitute also incorporates AEC-Q200 automotive qualification with 0.75W power rating. Packaged in Cut Tape format, this component meets all electrical and mechanical requirements. Selection is appropriate for automotive applications or where automotive-grade reliability standards are specified.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-074K75L replace RC5025F4751CS in any application?

A: Yes. RC2010FK-074K75L maintains identical resistance value (4.75 kOhms), tolerance (±1%), package dimensions (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The increased power rating (0.75W versus 0.667W) provides additional thermal margin without affecting electrical performance.

Q: What is the difference between the three substitute parts?

A: All three substitutes share identical electrical specifications (4.75 kOhms ±1%, 0.75W) and package format (2010). The primary differences are manufacturer identity and certifications. CRCW20104K75FKEF and RMCF2010FT4K75 include AEC-Q200 automotive qualification; RC2010FK-074K75L does not. Packaging format differs: RC2010FK-074K75L uses Tape & Reel, while RMCF2010FT4K75 uses Cut Tape.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts conform to the 2010 (5025 Metric) package standard with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated heights range from 0.026" to 0.028", which falls within standard PCB assembly tolerances and does not affect interchangeability.

Q: Which substitute should I select for automotive applications?

A: CRCW20104K75FKEF (Vishay Dale) or RMCF2010FT4K75 (Stackpole Electronics Inc) are appropriate for automotive applications, as both carry AEC-Q200 certification. Selection between these two depends on packaging preference (Tape & Reel versus Cut Tape) and supplier availability.

Q: Does the higher power rating of substitute parts affect circuit performance?

A: No. Higher power ratings indicate increased thermal capacity and do not alter electrical characteristics. The 0.75W rating of substitute parts provides improved thermal margin compared to the 0.667W original specification, resulting in lower operating temperatures under identical load conditions.

Q: Are all parts RoHS3 compliant?

A: Yes. The RC5025F4751CS and all three substitute parts maintain ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with modern manufacturing and environmental standards.
