Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J391CS is determined by the following mandatory parameters:

Electrical Compatibility:

• Resistance value: 390 Ohms (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or superior required)

Mechanical Compatibility:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Size / Dimension: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Number of Terminations: 2 (exact match required)

Regulatory & Environmental:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match or superior required)

Tolerance & Power Rating Flexibility: Tolerance may be tighter (±1%) than the original specification (±5%), representing an upgrade. Power rating may be equal or higher (0.75W or greater) than the original 0.667W specification, representing an upgrade. These parameters do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-07390RL (YAGEO) - Upgrade Substitute: This part qualifies as a direct upgrade substitute. It maintains all mandatory electrical and mechanical parameters while providing tighter tolerance (±1% versus ±5%) and increased power rating (0.75W versus 0.667W). Active product status and full RoHS3 compliance ensure regulatory alignment. Selection is appropriate for applications requiring improved tolerance performance without design modification.

RC2010JK-07390RL (YAGEO) - Upgrade Substitute: This part qualifies as a direct upgrade substitute. It maintains all mandatory electrical and mechanical parameters while providing increased power rating (0.75W versus 0.667W). Tolerance remains at ±5%, matching the original specification. Active product status and full RoHS3 compliance ensure regulatory alignment. Selection is appropriate for applications requiring increased power dissipation capability.

CRCW2010390RFKEF (Vishay Dale) - Similar Substitute: This part qualifies as a similar substitute with automotive-grade qualification. It maintains all mandatory electrical and mechanical parameters while providing tighter tolerance (±1% versus ±5%) and increased power rating (0.75W versus 0.667W). AEC-Q200 automotive qualification is an additional feature not present in the main part. Height dimension is 0.028" (0.70mm) versus 0.026" (0.66mm) for the main part; this remains within typical PCB assembly tolerances. Active product status and full RoHS3 compliance ensure regulatory alignment. Selection is appropriate for applications requiring automotive-grade reliability or improved tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07390RL replace RC5025J391CS in all applications? A: RC2010FK-07390RL qualifies as a direct substitute. It maintains identical resistance, temperature coefficient, operating temperature range, package dimensions, and regulatory compliance. The tighter tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W) represent improvements. No design modification is required.

Q: What is the difference between RC2010JK-07390RL and RC2010FK-07390RL? A: Both parts are YAGEO 2010 package 390 Ohm resistors with identical electrical and mechanical specifications. The primary difference is tolerance: RC2010JK-07390RL maintains ±5% tolerance matching the original part, while RC2010FK-07390RL provides ±1% tolerance. Both have 0.75W power rating and are suitable substitutes.

Q: Why does CRCW2010390RFKEF have a different height specification? A: CRCW2010390RFKEF has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.66mm) for the main part. This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect mechanical compatibility or board-level functionality. The part remains a valid substitute.

Q: Is CRCW2010390RFKEF suitable for automotive applications? A: CRCW2010390RFKEF carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The main part RC5025J391CS does not carry this certification. Selection of CRCW2010390RFKEF is appropriate when automotive reliability standards are required.

Q: Can I use a substitute part with higher power rating in a design rated for 0.667W? A: Yes. All substitute parts listed have power ratings of 0.75W or higher. Higher power rating indicates greater thermal capability and does not create incompatibility. The component will operate safely within the original design's power dissipation requirements.

Q: Are all substitute parts available in Tape & Reel packaging? A: RC2010FK-07390RL, RC2010JK-07390RL, and CRCW2010390RFKEF are all available in Tape & Reel (TR) packaging, suitable for automated assembly processes. Inventory availability is confirmed for all listed parts.

Q: Do all parts meet RoHS3 compliance? A: Yes. RC5025J391CS, RC2010FK-07390RL, RC2010JK-07390RL, and CRCW2010390RFKEF are all ROHS3 Compliant with MSL 1 (Unlimited) rating, ensuring regulatory alignment and environmental compliance.
