RC5025J751CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025J751CS is a 750 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when original inventory becomes unavailable, when alternative manufacturers offer improved specifications within the same package footprint, or when design requirements necessitate enhanced tolerance or power ratings while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RC5025J751CS are classified into two categories based on electrical parameter compatibility:

Upgrade Substitutes maintain the 750 Ohm resistance value and identical package dimensions (2010/5025 Metric) while offering improved power rating (0.75W vs. 0.667W) and/or tighter tolerance (±1% vs. ±5%). These parts are direct functional upgrades suitable for applications where the original specification can be exceeded without design impact.

Similar Substitutes provide equivalent electrical performance with automotive-grade AEC-Q200 qualification. These parts maintain 750 Ohm resistance, 0.75W power rating, and ±1% tolerance in the same 2010 package but include automotive reliability ratings.

Key substitution criteria:

• Resistance value: 750 Ohms (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• RoHS/REACH Compliance: ROHS3 Compliant, REACH Unaffected (maintained across all substitutes)

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-07750RL (YAGEO) is suitable for applications requiring tighter tolerance specification (±1% vs. ±5%) with increased power margin (0.75W vs. 0.667W). This upgrade substitute maintains all environmental and compliance certifications of the original part while providing enhanced performance headroom.

RC2010JK-07750RL (YAGEO) maintains the original ±5% tolerance specification while providing increased power rating (0.75W vs. 0.667W). This substitute is appropriate for direct replacement when original inventory is depleted and tolerance requirements remain unchanged.

CRCW2010750RFKEF (Vishay Dale) and RMCF2010FT750R (Stackpole Electronics Inc) are suitable for applications requiring automotive-grade reliability qualification (AEC-Q200). Both parts provide ±1% tolerance and 0.75W power rating with automotive certification. Selection between these two similar substitutes depends on supplier availability and procurement requirements.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing supply chain and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07750RL replace RC5025J751CS in any application?

A: RC2010FK-07750RL is electrically and mechanically compatible with RC5025J751CS. The substitute provides improved tolerance (±1% vs. ±5%) and higher power rating (0.75W vs. 0.667W). Height difference is minimal (0.65mm vs. 0.66mm), presenting no PCB layout constraints. Substitution is valid for all applications where the original part operates within specification.

Q: What is the difference between upgrade and similar substitute categories?

A: Upgrade substitutes (RC2010FK-07750RL, RC2010JK-07750RL) are manufactured by YAGEO and provide enhanced specifications while maintaining the same package footprint and environmental ratings as the original Samsung part. Similar substitutes (CRCW2010750RFKEF, RMCF2010FT750R) are automotive-grade parts with AEC-Q200 qualification, suitable for applications requiring automotive reliability standards.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, identical to the original RC5025J751CS specification.

Q: Does the height difference between main part and substitutes affect PCB design?

A: The height variation is minimal. RC5025J751CS has maximum seated height of 0.66mm, while YAGEO substitutes are 0.65mm and Vishay/Stackpole substitutes are 0.70mm. These differences are within standard PCB assembly tolerances and do not require design modification.

Q: Can RC2010JK-07750RL be used when ±1% tolerance is required?

A: No. RC2010JK-07750RL maintains ±5% tolerance identical to the original part. For applications requiring ±1% tolerance, use RC2010FK-07750RL, CRCW2010750RFKEF, or RMCF2010FT750R.

Q: Which substitute should be selected for automotive applications?

A: CRCW2010750RFKEF (Vishay Dale) or RMCF2010FT750R (Stackpole Electronics Inc) are appropriate for automotive applications, as both carry AEC-Q200 qualification. The original RC5025J751CS and YAGEO substitutes do not include automotive certification.
