Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J431CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 430 Ohms
• Tolerance: ±5%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Features: Moisture Resistant
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameter:

• Power Rating: Substitutes with equal or higher power rating (≥0.667W) are acceptable

The RC2010JK-07430RL from YAGEO qualifies as a substitute because it maintains all mandatory parameters while providing an upgraded power rating of 0.75W (3/4W), which exceeds the original 0.667W specification. This upgrade provides enhanced thermal margin without compromising electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC5025J431CS (Samsung Electro-Mechanics) is the primary specification. Selection is appropriate for applications where the 0.667W power rating is sufficient and Samsung sourcing is required.

RC2010JK-07430RL (YAGEO) is a qualified substitute offering increased power dissipation capability at 0.75W. This substitute is suitable for applications requiring enhanced thermal performance or where YAGEO component sourcing is preferred. Both parts maintain identical electrical characteristics, mechanical compatibility, and regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Selection between these parts is based on supply availability, procurement requirements, and thermal margin specifications rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC2010JK-07430RL replace RC5025J431CS in all applications?

A: Yes. The RC2010JK-07430RL maintains all critical electrical and mechanical parameters while providing a higher power rating (0.75W vs. 0.667W). The increased power rating does not create incompatibility; it provides additional thermal margin. Physical dimensions, resistance value, tolerance, temperature coefficient, and operating temperature range are identical.

Q: What is the significance of the power rating difference?

A: The RC2010JK-07430RL is rated for 0.75W compared to the RC5025J431CS at 0.667W. This 12.5% increase in power rating allows the YAGEO part to dissipate more heat without exceeding maximum junction temperature. In applications operating near the thermal limit of the original part, the substitute provides improved reliability margin.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated heights are equivalent at 0.026" (0.66mm for Samsung, 0.65mm for YAGEO), ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC5025J431CS and RC2010JK-07430RL are ROHS3 compliant, REACH Unaffected, and classified as EAR99 under ECCN. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the temperature coefficient specification?

A: Both parts specify ±100ppm/°C temperature coefficient across the operating range of -55°C to 155°C. This parameter is identical and ensures equivalent frequency stability and resistance drift characteristics in temperature-sensitive applications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions, footprint, and termination configuration (2 terminations) ensure direct PCB compatibility. No layout modifications or assembly process changes are required when substituting between these parts.
