Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F26R1CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 26.1 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as this represents a higher power capability within the same package footprint, providing equivalent or superior performance in the same circuit application.

The identified substitute parts meet all mandatory electrical and mechanical parameters while maintaining full compliance with environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

CRCW201026R1FKEF (Vishay Dale) is the primary substitute for the RC5025F26R1CS. This part maintains Active product status, ensuring continued manufacturer support and long-term availability. The CRCW201026R1FKEF provides identical electrical specifications with a higher power rating (0.75W versus 0.667W), delivering enhanced thermal margin within the same 2010 package footprint. Automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications. Packaging in Tape & Reel format supports automated assembly processes.

ERJ-12SF26R1U (Panasonic Electronic Components) is a secondary substitute option. While this part meets all electrical and mechanical compatibility requirements, it carries a "Not For New Designs" product status designation. This classification indicates that Panasonic has discontinued active development and marketing of this component line. Selection of ERJ-12SF26R1U is appropriate only for legacy system maintenance, repair, or where existing design validation has already been completed. For new circuit designs, CRCW201026R1FKEF is the recommended alternative.

Both substitute parts maintain full ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical operating temperature specifications (-55°C ~ 155°C), ensuring seamless integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW201026R1FKEF directly replace RC5025F26R1CS in existing circuit boards?

A: Yes. Both parts share identical resistance (26.1 Ohms), tolerance (±1%), package dimensions (2010 / 5025 Metric), and temperature specifications (-55°C ~ 155°C). The CRCW201026R1FKEF's higher power rating (0.75W versus 0.667W) provides equivalent or superior performance. Maximum seated height differs by 0.002" (0.04mm), which does not impact PCB assembly or clearance in standard 2010 package applications.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF26R1U?

A: This designation indicates that Panasonic has transitioned this product line away from active development and marketing. While ERJ-12SF26R1U remains functionally equivalent and available in current inventory, it is intended for sustaining production of existing designs only. For new circuit development, CRCW201026R1FKEF is the recommended substitute to ensure long-term component availability and manufacturer support.

Q: Are there differences in packaging format between these parts?

A: RC5025F26R1CS is supplied in standard packaging format. Both CRCW201026R1FKEF and ERJ-12SF26R1U are supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly. This packaging difference does not affect electrical performance or mechanical compatibility; it reflects modern manufacturing and logistics practices.

Q: Do all three parts meet the same compliance and environmental standards?

A: Yes. RC5025F26R1CS, CRCW201026R1FKEF, and ERJ-12SF26R1U are all ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All three parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficients (±100ppm/°C).

Q: What is the practical impact of the 0.083W power rating difference between RC5025F26R1CS and the substitute parts?

A: The RC5025F26R1CS is rated for 0.667W, while CRCW201026R1FKEF and ERJ-12SF26R1U are rated for 0.75W. In circuit applications where the original part dissipates power below 0.667W, both substitutes operate with additional thermal margin. In applications where power dissipation approaches or exceeds 0.667W, the substitute parts' higher rating ensures continued safe operation. The higher power rating does not degrade performance in lower-power applications.
