Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F1153CS are qualified based on the following criteria:

Electrical Equivalence:

• Identical resistance value: 115 kOhms
• Matching tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Compatibility:

• Package format: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Two terminations (standard chip resistor configuration)

Compliance & Environmental:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected classification

Power Rating Consideration: Substitute parts rated at 0.75W (3/4W) exceed the original 0.667W (2/3W) specification and are acceptable for direct substitution in applications where the original power rating is sufficient. The higher power rating of substitute parts provides additional thermal margin without affecting circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F1153CS): The Samsung Electro-Mechanics RC5025F1153CS remains the primary choice for applications requiring the specified 0.667W power rating with moisture-resistant thick film construction. This part is Active status with established supply availability.

Substitute Selection (CRCW2010115KFKEF or RMCF2010FT115K): Both substitute parts are qualified alternatives when supply constraints affect the primary part. The Vishay Dale CRCW2010115KFKEF and Stackpole Electronics RMCF2010FT115K offer identical electrical performance with enhanced power ratings (0.75W). Both substitute parts carry AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and identical environmental ratings (MSL 1). Selection between primary and substitute parts does not introduce compliance risk.

Inventory Considerations: RMCF2010FT115K (Stackpole) shows highest inventory availability at 9152 units, followed by CRCW2010115KFKEF (Vishay Dale) at 4760 units, with RC5025F1153CS (Samsung) at 1158 units.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010115KFKEF or RMCF2010FT115K be used as direct replacements for RC5025F1153CS?

A: Yes. Both substitute parts meet all electrical and mechanical requirements. The 0.75W power rating exceeds the original 0.667W specification, providing additional thermal capacity without affecting circuit operation. Physical dimensions, resistance value, tolerance, and temperature characteristics are identical.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: The substitute parts are rated for higher continuous power dissipation. In applications where the circuit dissipates less than 0.667W through the resistor, both ratings are functionally equivalent. The higher rating of substitute parts does not degrade performance or introduce incompatibility.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW2010115KFKEF and RMCF2010FT115K both carry AEC-Q200 automotive qualification. The original RC5025F1153CS does not specify automotive rating. If automotive qualification is required, substitute parts provide this additional certification.

Q: Do all three parts have identical physical dimensions?

A: Yes. All 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 0.026" (0.66mm) for RC5025F1153CS and 0.028" (0.70mm) for both substitute parts. This 0.002" difference is within standard PCB assembly tolerances.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component requires no special moisture control during storage, handling, or assembly. All three parts carry this rating, eliminating moisture-related compatibility concerns.

Q: Are there any compliance differences between the three parts?

A: No. All three parts are ROHS3 Compliant and REACH Unaffected. Compliance status is identical across all options.

Q: Which substitute part should be selected for new designs?

A: Both CRCW2010115KFKEF and RMCF2010FT115K are qualified for new designs. Selection between them depends on supply availability, packaging preference (both available in Tape & Reel format), and any existing supplier relationships. RMCF2010FT115K offers higher inventory availability.
