RC5025F105CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F105CS is a 1 MOhm ±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) continuous power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 882 units currently in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package format, dimensions, termination count). Alternative sources provide enhanced power ratings or automotive-grade certifications while maintaining core electrical parameters.

Substitute Part Grouping Explanation

Substitute parts for the RC5025F105CS are classified based on electrical and mechanical parameter alignment:

Upgrade Substitutes (AC2010FK-071ML, RC2010FK-071ML): These parts maintain identical resistance value (1 MOhm), tolerance (±1%), package format (2010), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is an increased power rating of 0.75W (3/4W) compared to the original 0.667W (2/3W), providing enhanced thermal headroom in the same physical footprint.

Similar Substitutes (CRCW20101M00FKEF, ERJ-12SF1004U, RMCF2010FT1M00): These parts match all electrical parameters (1 MOhm, ±1%, 0.75W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (2010 package, 2 terminations, MSL 1). Additional features include Automotive AEC-Q200 certification, which is not present in the original part but does not preclude substitution in non-automotive applications.

Substitution Criteria:

• Resistance value: 1 MOhm (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 2010 (5025 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature: -55°C to 155°C (exact match required)
• Power rating: Equal to or greater than 0.667W (upgrade acceptable)
• Composition: Thick Film (exact match required)
• Terminations: 2 (exact match required)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): The RC5025F105CS maintains Active product status with established supply availability. Direct replacement with identical specifications is not available from alternative manufacturers without accepting either increased power rating or automotive certification additions.

For Upgrade Substitution (Enhanced Power Rating): AC2010FK-071ML and RC2010FK-071ML provide 0.75W power rating in the identical 2010 package with matching electrical parameters. Both manufacturers maintain Active product status. AC2010FK-071ML includes Automotive AEC-Q200 certification; RC2010FK-071ML does not. Selection between these depends on application requirements for automotive qualification.

For Automotive-Grade Applications: CRCW20101M00FKEF (Vishay Dale), ERJ-12SF1004U (Panasonic), and RMCF2010FT1M00 (Stackpole) all carry Automotive AEC-Q200 certification with 0.75W power rating. CRCW20101M00FKEF and RMCF2010FT1M00 maintain Active product status. ERJ-12SF1004U carries "Not For New Designs" status, limiting suitability for new development programs.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating identical to the original part. No compliance barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071ML replace RC5025F105CS in existing designs? A: Yes. AC2010FK-071ML matches all critical electrical parameters (1 MOhm, ±1%, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (2010 package, 2 terminations). The increased power rating (0.75W vs. 0.667W) is a beneficial upgrade that does not affect circuit compatibility. The addition of Automotive AEC-Q200 certification does not preclude use in non-automotive applications.

Q: What is the difference between upgrade and similar substitutes? A: Upgrade substitutes (AC2010FK-071ML, RC2010FK-071ML) provide enhanced power rating while maintaining all other specifications. Similar substitutes (CRCW20101M00FKEF, ERJ-12SF1004U, RMCF2010FT1M00) match all specifications including power rating but add Automotive AEC-Q200 certification. Both categories are electrically and mechanically compatible.

Q: Why does ERJ-12SF1004U show "Not For New Designs" status? A: ERJ-12SF1004U carries "Not For New Designs" designation from Panasonic. While electrically and mechanically compatible with RC5025F105CS, this status indicates the manufacturer recommends alternative parts for new development programs. Existing inventory remains available for legacy system support.

Q: Are all substitute parts available in the same packaging format? A: Yes. All substitute parts use the 2010 (5025 Metric) package format with identical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and 2-termination configuration. Physical board layout compatibility is maintained across all alternatives.

Q: What is the significance of MSL 1 rating for all parts? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All parts in this comparison, including the original RC5025F105CS, carry MSL 1 rating, eliminating moisture handling as a substitution constraint.

Q: Can I use CRCW20101M00FKEF in a non-automotive application? A: Yes. Automotive AEC-Q200 certification indicates the part meets automotive industry reliability standards but does not restrict use in non-automotive applications. CRCW20101M00FKEF is fully compatible with RC5025F105CS in any application where the original part was specified.

Q: What inventory levels are available for each substitute? A: AC2010FK-071ML: 6,287 units; RC2010FK-071ML: 8,200 units; CRCW20101M00FKEF: 209,225 units; ERJ-12SF1004U: 14,035 units; RMCF2010FT1M00: 14,311 units. Original RC5025F105CS: 882 units. Substitute parts offer significantly higher availability.
