Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025J301CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 300 Ohms (exact match required)
• Package / Case: 2010 (5025 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability)
• Operating Temperature Range: -55°C ~ 155°C (thermal envelope)
• RoHS3 Compliance and MSL 1 rating (regulatory and environmental requirements)

Allowable Variations:

• Tolerance: ±1% or ±5% (tighter tolerance acceptable for ±5% requirement)
• Power Rating: 0.75W (3/4W) or higher (higher power rating acceptable for 0.667W requirement)
• Manufacturer: Different manufacturers acceptable if all parameters align

Identified substitute parts meet all critical parameters while offering enhanced specifications in tolerance and/or power rating. All substitutes maintain identical package dimensions, thermal characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-07300RL (YAGEO Upgrade) This substitute offers improved tolerance specification (±1% versus ±5%) and increased power rating (0.75W versus 0.667W) while maintaining all critical electrical and thermal parameters. Suitable for applications requiring tighter resistance tolerance and higher power dissipation margin. All compliance certifications (RoHS3, MSL 1) are equivalent.

RC2010JK-07300RL (YAGEO Upgrade) This substitute maintains the original ±5% tolerance specification while providing increased power rating (0.75W versus 0.667W). Electrical and thermal characteristics remain identical to the main part. Recommended for direct replacement when higher power margin is required without tolerance modification. All compliance certifications are equivalent.

RMCF2010FT300R (Stackpole Electronics Inc) This substitute provides ±1% tolerance and 0.75W power rating with additional AEC-Q200 automotive qualification. Suitable for applications requiring automotive-grade reliability and tighter tolerance specifications. All thermal and electrical parameters align with the main part. RoHS3 and MSL 1 compliance maintained.

All substitute parts are Active status products with full inventory availability and maintain identical package dimensions, thermal operating ranges, and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07300RL replace RC5025J301CS in all applications? A: RC2010FK-07300RL is electrically and mechanically compatible. It provides ±1% tolerance (tighter than the original ±5%) and 0.75W power rating (higher than the original 0.667W). Both parts share identical package dimensions (2010/5025 Metric), thermal operating range (-55°C ~ 155°C), and compliance certifications. Substitution is valid for direct replacement.

Q: What is the difference between RC2010JK-07300RL and RC2010FK-07300RL? A: Both are YAGEO 2010 package resistors with 300 Ohm resistance and 0.75W power rating. The primary difference is tolerance: RC2010JK-07300RL maintains ±5% tolerance (matching the original part), while RC2010FK-07300RL offers ±1% tolerance. Both are mechanically and thermally identical.

Q: Why is RMCF2010FT300R listed as a substitute if it has AEC-Q200 rating? A: RMCF2010FT300R meets all critical substitution parameters: 300 Ohm resistance, 2010 package, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and RoHS3 compliance. The AEC-Q200 automotive qualification is an additional feature that does not prevent substitution; it indicates enhanced reliability testing and is acceptable for general industrial applications.

Q: Are all substitute parts available in the same packaging format? A: RC2010FK-07300RL and RC2010JK-07300RL are supplied in Tape & Reel (TR) format. RMCF2010FT300R is also supplied in Tape & Reel (TR) format. All three substitutes are compatible with automated assembly equipment designed for 2010 package components.

Q: Do all parts have the same moisture sensitivity level? A: Yes. The main part RC5025J301CS and all substitute parts (RC2010FK-07300RL, RC2010JK-07300RL, RMCF2010FT300R) are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All parts share identical physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm), identical package type (2010/5025 Metric), and identical number of terminations (2). PCB footprints designed for RC5025J301CS accommodate all listed substitutes without modification.
