Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J242CS is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Resistance value: 2.4 kOhms (exact match required)
• Package / Case: 2010 (5025 Metric) (physical and electrical footprint compatibility)
• Temperature Coefficient: ±100ppm/°C (thermal stability equivalence)
• Operating Temperature Range: -55°C ~ 155°C (environmental operating window)
• Composition: Thick Film (material consistency)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
• RoHS Status: ROHS3 Compliant (regulatory alignment)

Allowable Variation Parameters:

• Tolerance: ±5% (original) to ±1% (tighter tolerance acceptable as upgrade)
• Power Rating: 0.667W (original) to 0.75W (higher power rating acceptable as upgrade)
• Manufacturer: Samsung Electro-Mechanics, YAGEO, Vishay Dale, Stackpole Electronics Inc
• Packaging: Bulk or Tape & Reel (TR)
• Features: Moisture Resistant (standard) or Automotive AEC-Q200 (enhanced specification)

All identified substitute parts maintain identical resistance, package dimensions, temperature characteristics, and regulatory compliance while offering improved tolerance accuracy or increased power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance, Upgraded Power): RC2010JK-072K4L (YAGEO) maintains the original ±5% tolerance specification while providing increased 0.75W power rating in the identical 2010 package. This part is suitable for direct substitution where tolerance requirements remain unchanged and thermal margin improvement is beneficial.

Upgraded Tolerance Selection: RC2010FK-072K4L (YAGEO) and RMCF2010FT2K40 (Stackpole Electronics Inc) both provide ±1% tolerance with 0.75W power rating. These parts are appropriate for applications requiring tighter resistance accuracy while maintaining full thermal and environmental compatibility.

Automotive-Grade Specification: CRCW20102K40FKEF (Vishay Dale) and RMCF2010FT2K40 (Stackpole Electronics Inc) carry AEC-Q200 automotive qualification. These parts are required for automotive applications or systems subject to automotive-grade reliability standards while maintaining ±1% tolerance and 0.75W power rating.

All substitute parts are ROHS3 compliant, MSL 1 rated, and operate across the identical -55°C to 155°C temperature range. Selection between alternatives depends on tolerance requirements, automotive qualification necessity, and manufacturer preference within the supply chain.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072K4L replace RC5025J242CS in any application? A: RC2010FK-072K4L is a direct substitute with identical resistance, package, and operating temperature range. The ±1% tolerance is tighter than the original ±5%, and the 0.75W power rating exceeds the original 0.667W specification. Substitution is valid for all applications where the original part was specified.

Q: What is the difference between RC2010JK-072K4L and RC2010FK-072K4L? A: Both parts are manufactured by YAGEO in the 2010 package with 0.75W power rating and identical thermal characteristics. RC2010JK-072K4L maintains ±5% tolerance matching the original RC5025J242CS. RC2010FK-072K4L provides tighter ±1% tolerance. Selection depends on tolerance requirements of the application.

Q: Are CRCW20102K40FKEF and RMCF2010FT2K40 interchangeable? A: Both parts are functionally equivalent with 2.4 kOhms resistance, ±1% tolerance, 0.75W power rating, 2010 package, and AEC-Q200 automotive qualification. They differ only in manufacturer (Vishay Dale versus Stackpole Electronics Inc). Interchangeability depends on supply chain and procurement specifications.

Q: Why do substitute parts have higher power ratings? A: The substitute parts (0.75W) provide increased thermal margin compared to the original (0.667W) while maintaining identical physical dimensions and package footprint. Higher power rating does not affect circuit operation but improves reliability under thermal stress conditions.

Q: Can I use automotive-grade parts (AEC-Q200) in non-automotive applications? A: Yes. Automotive-grade parts meet or exceed standard industrial specifications. CRCW20102K40FKEF and RMCF2010FT2K40 are fully compatible with non-automotive applications and provide enhanced reliability characteristics.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory alignment and handling compatibility with the original RC5025J242CS.

Q: What packaging options are available for substitute parts? A: Substitute parts are available in Tape & Reel (TR) packaging format. The original RC5025J242CS is available in bulk packaging. Both packaging formats are compatible for PCB assembly processes.
