Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F910CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 91 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher satisfy applications requiring 0.667W (2/3W) due to derating margin
• Packaging format: Tape & Reel (TR) acceptable for automated assembly; original part packaging not specified

The identified substitute parts RC2010FK-0791RL and AC2010FK-0791RL meet all mandatory parameters with increased power rating capability. AC2010FK-0791RL additionally includes AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-0791RL (YAGEO): This substitute part provides direct functional equivalence to the RC5025F910CS with identical electrical specifications and package dimensions. The increased power rating of 0.75W (3/4W) versus 0.667W (2/3W) provides additional thermal margin without affecting circuit performance. Both parts maintain ROHS3 compliance, unlimited MSL rating, and identical temperature coefficient characteristics. Selection is appropriate for general industrial and consumer applications requiring 91 Ohm resistive elements.

AC2010FK-0791RL (YAGEO): This substitute part meets all electrical and mechanical equivalence criteria while adding AEC-Q200 automotive qualification. The automotive-grade certification indicates compliance with automotive reliability and environmental stress testing standards. Selection is appropriate for automotive applications, industrial equipment subject to stringent reliability requirements, or designs requiring documented automotive-grade component traceability. The increased power rating of 0.75W (3/4W) applies identically to this variant.

Both substitute parts are Active status components with confirmed inventory availability, supporting immediate procurement and design implementation.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0791RL or AC2010FK-0791RL be used as direct replacements for RC5025F910CS in existing designs?

A: Yes. Both substitute parts are electrically and mechanically equivalent. Identical resistance (91 Ohms), tolerance (±1%), package format (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) ensure direct substitution without circuit redesign. The increased power rating (0.75W versus 0.667W) provides additional thermal capability.

Q: What is the significance of the higher power rating on the substitute parts?

A: The substitute parts are rated for 0.75W (3/4W) compared to the original 0.667W (2/3W). This higher rating indicates greater thermal dissipation capability under continuous operation. For applications requiring 0.667W, the substitute parts operate with additional derating margin, improving reliability and thermal stability without affecting electrical performance.

Q: When should AC2010FK-0791RL be selected over RC2010FK-0791RL?

A: AC2010FK-0791RL includes AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability and environmental testing standards. Selection of AC2010FK-0791RL is appropriate for automotive applications, designs requiring documented automotive-grade component certification, or systems subject to automotive-level reliability requirements. For non-automotive applications, RC2010FK-0791RL provides equivalent electrical and mechanical performance.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts conform to the 2010 (5025 Metric) package format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Maximum seated height is 0.026" (0.66mm for RC5025F910CS, 0.65mm for both YAGEO variants), representing negligible variation within standard PCB assembly tolerances.

Q: Do all parts maintain the same moisture sensitivity level?

A: Yes. RC5025F910CS, RC2010FK-0791RL, and AC2010FK-0791RL all carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. All parts are suitable for standard storage conditions and do not require special moisture-controlled packaging or baking procedures prior to assembly.

Q: Are there any compliance or regulatory differences between the three parts?

A: All three parts are ROHS3 compliant and REACH Unaffected. AC2010FK-0791RL additionally carries AEC-Q200 automotive qualification. For non-automotive applications, compliance profiles are identical. For automotive applications, AC2010FK-0791RL provides documented automotive-grade certification.
