RC5025F102CS Equivalent & Substitute Parts

Part Overview

The RC5025F102CS is a 1 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with 0.667W power rating. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the original manufacturer part experiences supply constraints, extended lead times, or when design requirements call for enhanced specifications such as higher power ratings or automotive-grade certifications. The substitute parts listed maintain electrical equivalence while offering alternative sourcing options and, in some cases, upgraded performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)

Secondary Compatibility Factors:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher satisfy the 0.667W requirement of the main part
• RoHS and REACH compliance status
• Moisture Sensitivity Level: MSL 1 (Unlimited) maintained across all substitutes
• Product status and availability

All substitute parts listed meet or exceed the primary substitution criteria. Differences in power rating, manufacturer, and certifications are noted in the parameter comparison table.

Engineering Selection Recommendations

Preferred Substitutes (Active Status, ROHS3 Compliant):

AC2010FK-071KL, RC2010FK-071KL, CRCW20101K00FKEF, and RMCF2010FT1K00 are suitable direct substitutes. All maintain electrical equivalence with the RC5025F102CS while offering 0.75W power rating, providing design margin above the original 0.667W specification. AC2010FK-071KL, CRCW20101K00FKEF, and RMCF2010FT1K00 include AEC-Q200 automotive qualification, beneficial for applications requiring automotive-grade component reliability.

Conditional Substitute:

CRCW20101K00FKTF is electrically equivalent but carries RoHS non-compliant status and REACH Affected designation. This part is suitable only for applications where RoHS3 compliance is not a requirement.

Legacy Status:

ERJ-12SF1001U is marked "Not For New Designs" by Panasonic. While electrically equivalent and ROHS3 compliant with AEC-Q200 certification, this part should not be selected for new product development. Existing designs currently using this part may continue sourcing until end-of-life.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC5025F102CS with a higher power-rated resistor?

A: Yes. All listed substitute parts are rated at 0.75W (3/4W), which exceeds the original 0.667W requirement. Higher power ratings provide thermal margin and do not affect electrical performance in the circuit. Physical dimensions remain identical at 2010 (5025 Metric) package.

Q: What is the difference between the YAGEO AC2010FK-071KL and RC2010FK-071KL?

A: Both are YAGEO 1 kOhms ±1% 0.75W 2010 package resistors with identical electrical specifications. AC2010FK-071KL includes AEC-Q200 automotive qualification; RC2010FK-071KL does not. Selection depends on whether automotive-grade certification is required for your application.

Q: Why is CRCW20101K00FKTF marked as RoHS non-compliant?

A: CRCW20101K00FKTF is RoHS non-compliant and REACH Affected. This part should be used only in applications or regions where RoHS3 compliance is not mandated. For new designs, select CRCW20101K00FKEF (RoHS3 compliant) instead.

Q: Should I use ERJ-12SF1001U for new designs?

A: No. ERJ-12SF1001U is marked "Not For New Designs" by Panasonic. This designation indicates the manufacturer is phasing out this part. For new product development, select from AC2010FK-071KL, RC2010FK-071KL, CRCW20101K00FKEF, or RMCF2010FT1K00.

Q: Are all substitute parts available in the same packaging formats?

A: Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Verify packaging availability with your supplier before finalizing procurement. All parts maintain the same 2010 (5025 Metric) physical package.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts carrying this certification meet stringent reliability and performance requirements for automotive applications. AC2010FK-071KL, CRCW20101K00FKEF, ERJ-12SF1001U, and RMCF2010FT1K00 include this certification.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes. All substitute parts are electrically equivalent with identical resistance, tolerance, temperature coefficient, and operating temperature range. Mixing different manufacturers on the same board is acceptable from an electrical standpoint. Verify procurement and inventory management procedures with your supply chain team.
