RC5025F1273CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F1273CS is a 127 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is currently in stock with 878 pieces available.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The RC5025F1273CS can be substituted with components that maintain identical resistance value, tolerance, package dimensions, and operating temperature range while meeting the same compliance standards.

Substitute Part Grouping Explanation

Substitution logic for the RC5025F1273CS is based strictly on the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Resistance value: 127 kOhms (exact match required)
• Tolerance: ±1% (substitute must meet or exceed this specification)
• Package designation: 2010 (5025 Metric) (physical footprint compatibility)
• Composition: Thick Film (electrical behavior consistency)
• Temperature coefficient: ±100ppm/°C (performance stability)
• Operating temperature range: -55°C ~ 155°C (environmental suitability)
• RoHS3 compliance (regulatory requirement)

Acceptable Variation:

• Power rating: Substitute must equal or exceed 0.667W minimum
• Physical dimensions: Must conform to 2010 package standard (0.197" L x 0.098" W / 5.00mm x 2.50mm)
• Moisture Sensitivity Level: MSL 1 or better acceptable

The identified substitute ERJ-12SF1273U meets all mandatory criteria with a higher power rating (0.75W) and maintains identical electrical specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC5025F1273CS): The RC5025F1273CS maintains Active product status from Samsung Electro-Mechanics, indicating ongoing manufacturing support and suitability for new design implementations. This component is recommended for new applications where long-term availability and manufacturer support are required. Current inventory of 878 pieces supports immediate procurement needs.

Substitute Component (ERJ-12SF1273U): The ERJ-12SF1273U from Panasonic Electronic Components is electrically and mechanically equivalent to the RC5025F1273CS. However, this component carries "Not For New Designs" product status, indicating that Panasonic has discontinued active development and support for this part number. The ERJ-12SF1273U is suitable only for replacement, repair, or maintenance applications where the component is already in use within existing designs.

Compliance Considerations: Both components maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both components are classified under ECCN EAR99 and HTSUS 8533.21.0030, indicating equivalent export and tariff classification.

Selection Criteria:

• For new designs: Use RC5025F1273CS (Active status)
• For replacement or repair: ERJ-12SF1273U is acceptable if supply of primary component is unavailable
• Both components are suitable for applications requiring -55°C ~ 155°C operating temperature range
• Both components support unlimited moisture handling (MSL 1)

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1273U be used as a direct replacement for RC5025F1273CS in new designs?

A: No. While ERJ-12SF1273U meets all electrical and mechanical specifications, it carries "Not For New Designs" product status. For new designs, RC5025F1273CS is the appropriate selection. ERJ-12SF1273U is suitable only for replacement or repair of existing applications.

Q: What is the significance of the different power ratings (0.667W vs 0.75W)?

A: The ERJ-12SF1273U has a higher power rating (0.75W) than the RC5025F1273CS (0.667W). A higher power rating is acceptable in substitution because it provides equal or greater thermal capability. The substitute will not create thermal stress in applications designed for the lower-rated component.

Q: Are the physical dimensions identical between these two components?

A: The components share identical length and width dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and both use the 2010 (5025 Metric) package designation. The seated height differs slightly (0.026" vs 0.028"), but this variation remains within standard package tolerances and does not affect PCB assembly compatibility.

Q: Do both components meet the same compliance standards?

A: Yes. Both RC5025F1273CS and ERJ-12SF1273U are ROHS3 compliant, REACH Unaffected, and classified under identical ECCN and HTSUS codes. Both maintain MSL 1 (Unlimited) moisture sensitivity level, indicating equivalent handling and storage requirements.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: "Active" status indicates the manufacturer continues production and provides full support for the component. "Not For New Designs" indicates the manufacturer has discontinued active development but may continue limited production for existing customer applications. This distinction affects long-term availability and manufacturer support, not electrical performance.

Q: Can these components be used interchangeably in existing applications?

A: Yes, for replacement or repair purposes. Both components have identical resistance, tolerance, temperature coefficient, and operating temperature range. The higher power rating of the substitute provides equivalent or improved thermal performance.

Q: What inventory considerations should be evaluated?

A: RC5025F1273CS has 878 pieces in stock (Active status), while ERJ-12SF1273U has 2591 pieces available (Not For New Designs status). For immediate procurement, ERJ-12SF1273U offers higher availability, but for long-term supply assurance in new designs, RC5025F1273CS is the appropriate selection.
