RC5025F111CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F111CS is a 110 Ohms ±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 full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is suitable for general-purpose applications requiring precision resistive elements in compact surface-mount form factors.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package dimensions, termination count) while maintaining compliance certifications. Substitute parts with higher power ratings (0.75W) provide design margin for thermal performance in demanding applications.

These parts maintain identical electrical parameters (110 Ohms ±1%, 2010 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) while providing increased power rating (0.75W vs. 0.667W). Both are Active product status with ROHS3 compliance and MSL 1 rating.

Similar Substitutes (Equivalent specifications with alternative manufacturers):

CRCW2010110RFKEF (Vishay Dale)
ERJ-12SF1100U (Panasonic Electronic Components)
RMCF2010FT110R (Stackpole Electronics Inc)

These parts match all critical electrical and mechanical parameters. ERJ-12SF1100U carries "Not For New Designs" product status. CRCW2010110RFKEF and RMCF2010FT110R are Active status. All three provide 0.75W power rating with identical package, tolerance, temperature coefficient, and operating range specifications.

Engineering Selection Recommendations

For New Designs: Select AC2010FK-07110RL, RC2010FK-07110RL, CRCW2010110RFKEF, or RMCF2010FT110R. All four parts carry Active product status with full RoHS3 compliance and MSL 1 rating. These substitutes provide identical electrical performance with increased power margin (0.75W vs. 0.667W), supporting thermal design robustness in production environments.

For Existing Designs (Direct Replacement): RC2010FK-07110RL (YAGEO) or AC2010FK-07110RL (YAGEO) are preferred for direct substitution of RC5025F111CS. Both maintain identical package footprint, electrical specifications, and compliance certifications while offering enhanced power rating.

For Automotive Applications: AC2010FK-07110RL, CRCW2010110RFKEF, and RMCF2010FT110R include AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs requiring additional reliability assurance.

Avoid for New Designs: ERJ-12SF1100U carries "Not For New Designs" product status. This part is suitable only for legacy design maintenance or existing production continuity where design changes are not feasible.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification matching the original RC5025F111CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07110RL replace RC5025F111CS directly on the PCB?

A: Yes. Both parts use identical 2010 (5025 Metric) package dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) with 2 terminations. PCB footprint compatibility is confirmed. The substitute provides higher power rating (0.75W vs. 0.667W), which is a non-critical upgrade for thermal performance.

Q: What is the difference between "Upgrade Substitute" and "Similar Substitute" classifications?

A: Upgrade Substitutes (AC2010FK-07110RL, RC2010FK-07110RL) are from the same manufacturer ecosystem (YAGEO) with enhanced power ratings. Similar Substitutes (CRCW2010110RFKEF, ERJ-12SF1100U, RMCF2010FT110R) are from alternative manufacturers with equivalent specifications. All meet the mandatory matching parameters for electrical and mechanical compatibility.

Q: Is the 0.75W power rating of substitute parts compatible with designs specified for 0.667W?

A: Yes. Higher power rating indicates greater thermal capacity. A 0.75W-rated component can operate safely in circuits designed for 0.667W dissipation. This represents a design margin improvement with no negative impact on circuit performance.

Q: Why is ERJ-12SF1100U marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development for this part number. While electrically and mechanically equivalent, it is retained for legacy production support only. New designs should select AC2010FK-07110RL, RC2010FK-07110RL, CRCW2010110RFKEF, or RMCF2010FT110R.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC5025F111CS specification.

Q: What packaging formats are available for these substitutes?

A: AC2010FK-07110RL and RC2010FK-07110RL are supplied in Tape & Reel (TR) format. CRCW2010110RFKEF and ERJ-12SF1100U are available in Tape & Reel (TR). RMCF2010FT110R is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: AC2010FK-07110RL, CRCW2010110RFKEF, and RMCF2010FT110R include AEC-Q200 automotive qualification. These three parts are suitable for automotive-grade designs. RC2010FK-07110RL and ERJ-12SF1100U do not carry AEC-Q200 rating and should be evaluated for automotive use based on specific application requirements.
