Substitute Part Grouping Explanation

Substitute parts for the RC5025J910CS are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Resistance Value: 91 Ohms (exact match required)
• Package / Case: 2010 (5025 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability equivalence)
• Operating Temperature Range: -55°C ~ 155°C (thermal envelope compatibility)
• Moisture Resistance: Present (environmental protection consistency)
• RoHS Status: ROHS3 Compliant (regulatory alignment)
• MSL Rating: 1 (Unlimited) (handling and storage compatibility)

Allowable Parameter Variations:

• Tolerance: Substitutes may have tighter tolerance (±1% acceptable for ±5% requirement)
• Power Rating: Substitutes may have equal or higher power rating (0.75W acceptable for 0.667W requirement)
• Manufacturer: Different manufacturers permitted when all other parameters align
• Packaging Format: Tape & Reel (TR) acceptable as alternative to standard packaging

The two identified substitute parts meet all mandatory matching criteria while offering improved tolerance specifications and increased power handling capacity, making them suitable direct replacements in applications where the RC5025J910CS is specified.

Parameter Comparison

Engineering Selection Recommendations

Both RC2010FK-0791RL and AC2010FK-0791RL qualify as direct substitutes for the RC5025J910CS based on electrical and mechanical parameter alignment. Selection between alternatives should be based on the following criteria:

RC2010FK-0791RL (YAGEO): This substitute provides improved tolerance specification (±1% versus ±5%) and increased power rating (0.75W versus 0.667W) while maintaining identical thermal and environmental characteristics. The part is ROHS3 compliant and carries MSL 1 rating. This option is suitable for general industrial applications requiring enhanced precision and thermal margin.

AC2010FK-0791RL (YAGEO): This substitute offers the same electrical and mechanical improvements as RC2010FK-0791RL with the additional qualification of AEC-Q200 automotive certification. This part is appropriate for automotive and automotive-grade applications where component qualification to automotive standards is required or preferred.

Both substitute parts are available in Tape & Reel (TR) packaging format, which may require process adjustment if the original design specifies alternative packaging. All three parts maintain identical operating temperature ranges, moisture resistance characteristics, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0791RL or AC2010FK-0791RL be used as direct replacements for RC5025J910CS without circuit modification?

A: Yes. Both substitute parts maintain identical resistance value (91 Ohms), package configuration (2010/5025 Metric), thermal characteristics (±100ppm/°C, -55°C to 155°C), and moisture resistance. The improved tolerance (±1% versus ±5%) and increased power rating (0.75W versus 0.667W) are compatible with applications designed for the original part.

Q: What is the difference between RC2010FK-0791RL and AC2010FK-0791RL?

A: Both parts are electrically and mechanically identical with one distinction: AC2010FK-0791RL carries AEC-Q200 automotive qualification certification, while RC2010FK-0791RL does not. Select AC2010FK-0791RL for automotive applications requiring this certification; either part is acceptable for non-automotive applications.

Q: Are the substitute parts available in the same packaging format as the original RC5025J910CS?

A: The substitute parts are supplied in Tape & Reel (TR) packaging format. If the original design specifies alternative packaging, packaging format compatibility must be confirmed with procurement or manufacturing processes.

Q: Do the substitute parts have the same moisture sensitivity level as the RC5025J910CS?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements.

Q: What is the physical dimension compatibility between the main part and substitutes?

A: All parts share the same 2010 (5025 Metric) package configuration with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.66mm for RC5025J910CS, 0.65mm for substitutes), representing negligible variation within standard PCB assembly tolerances.

Q: Are all three parts RoHS compliant?

A: Yes. RC5025J910CS, RC2010FK-0791RL, and AC2010FK-0791RL are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part should be selected for improved circuit performance?

A: Both substitute parts offer improved tolerance (±1% versus ±5%) and increased power handling (0.75W versus 0.667W). For automotive applications, AC2010FK-0791RL is the appropriate selection. For general industrial applications, either RC2010FK-0791RL or AC2010FK-0791RL is acceptable based on availability and procurement preference.
