RC5025F1023CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F1023CS is a 102 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). This resistor is designed for general-purpose applications requiring precision tolerance and moisture resistance in compact surface-mount form factors. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the RC5025F1023CS are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Primary Matching Criteria:

• Resistance value: 102 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 2010 (5025 Metric) (exact match required for PCB footprint compatibility)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (substitute must support this range)

Secondary Compatibility Criteria:

• Power rating: Substitute must equal or exceed 0.667W
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Moisture sensitivity: MSL 1 or better (handling compatibility)

The RMCF2010FT102K from Stackpole Electronics Inc qualifies as a substitute because it maintains all primary matching criteria while providing a higher power rating (0.75W vs. 0.667W), which is acceptable for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT102K is electrically and mechanically compatible with the RC5025F1023CS for direct substitution in applications requiring a 102 kOhms ±1% resistor in 2010 package format.

Substitution Basis:

1. Electrical Equivalence: Both parts maintain identical resistance value (102 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

2. Mechanical Compatibility: Both components use the 2010 (5025 Metric) package with matching footprint dimensions (5.00mm x 2.50mm). The seated height difference (0.66mm vs. 0.70mm) is within acceptable PCB assembly tolerances.

3. Power Rating: The RMCF2010FT102K provides 0.75W power rating, which exceeds the RC5025F1023CS requirement of 0.667W, ensuring adequate thermal performance in equivalent or less demanding applications.

4. Regulatory Compliance: Both parts are ROHS3 compliant and carry MSL 1 rating, meeting identical handling and environmental requirements.

5. Product Status: Both components maintain Active product status, ensuring continued availability and manufacturing support.

6. Additional Qualification: The RMCF2010FT102K carries AEC-Q200 automotive qualification, which provides enhanced reliability assurance for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2010FT102K replace the RC5025F1023CS in all applications?

A: Yes, the RMCF2010FT102K is electrically and mechanically equivalent. The higher power rating (0.75W vs. 0.667W) and automotive AEC-Q200 qualification make it suitable for all applications where the RC5025F1023CS is specified.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use identical 2010 (5025 Metric) package dimensions (5.00mm x 2.50mm). The seated height difference of 0.04mm (0.70mm vs. 0.66mm) is negligible for standard PCB assembly processes.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both the RC5025F1023CS and RMCF2010FT102K carry MSL 1 (Unlimited) rating, requiring identical handling, storage, and moisture control procedures.

Q: What is the significance of the AEC-Q200 qualification on the RMCF2010FT102K?

A: AEC-Q200 is an automotive industry qualification standard. The RMCF2010FT102K meets enhanced reliability and performance requirements for automotive applications. This qualification does not restrict use in non-automotive applications.

Q: Are the temperature coefficients identical?

A: Yes. Both parts specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C.

Q: Is there any difference in RoHS compliance between these parts?

A: No. Both the RC5025F1023CS and RMCF2010FT102K are ROHS3 compliant, meeting identical environmental and regulatory requirements.

Q: Can the RMCF2010FT102K be used in high-temperature applications?

A: Yes. The RMCF2010FT102K operates to 155°C maximum, matching the RC5025F1023CS upper temperature limit. Both parts are suitable for applications within this temperature range.
