RC6432F4872CS Equivalent & Substitute Parts

Part Overview

The RC6432F4872CS is a 48.7 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4872CS is determined by strict alignment of the following parameters:

Electrical Specifications: Resistance value (48.7 kOhms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance equivalence.

Mechanical Compatibility: Package designation (2512 / 6432 Metric) and number of terminations (2) ensure physical and electrical interface compatibility. Dimensional variations within supplier device package specifications are acceptable provided PCB footprint compatibility is maintained.

Compliance & Environmental: RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) establish regulatory and environmental equivalence. Additional certifications such as AEC-Q200 do not disqualify substitution but indicate enhanced qualification for specific applications.

Product Status Consideration: Active status indicates ongoing manufacturing and supply availability. Substitute parts with "Not For New Designs" status remain functionally equivalent but may have limited future availability.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-1TNF4872U (Panasonic Electronic Components) qualifies as a direct electrical and mechanical substitute for the RC6432F4872CS. All critical parameters—resistance, tolerance, power rating, temperature coefficient, operating temperature range, package type, and compliance certifications—are equivalent.

Dimensional Consideration: The ERJ-1TNF4872U exhibits minor dimensional variations (length 6.40mm vs. 6.30mm; height 0.70mm vs. 0.66mm). These differences remain within standard PCB footprint tolerances for 2512 package components and do not affect functional compatibility.

Product Status: The RC6432F4872CS maintains Active status, indicating current manufacturing and supply continuity. The ERJ-1TNF4872U carries "Not For New Designs" status, indicating Panasonic has discontinued active promotion of this part number. Selection of the RC6432F4872CS is preferred for new designs requiring long-term supply assurance. The ERJ-1TNF4872U remains suitable for replacement, repair, and legacy system applications where supply availability is confirmed.

Certification Alignment: Both parts achieve ROHS3 compliance and REACH unaffected status. The ERJ-1TNF4872U includes AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive and high-reliability applications but does not alter substitution eligibility for general industrial use.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-1TNF4872U replace the RC6432F4872CS in existing designs?

A: Yes. The ERJ-1TNF4872U is electrically and mechanically equivalent. Resistance (48.7 kOhms ±1%), power rating (1W), temperature performance (±100ppm/°C, -55°C ~ 155°C), and package type (2512) are identical. Minor dimensional variations (0.1mm length, 0.04mm height) fall within standard PCB footprint tolerances and do not affect circuit performance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF4872U?

A: This designation indicates Panasonic has concluded active development and promotion of this part number. The component remains functionally equivalent and available from existing inventory. For new product designs requiring extended supply assurance, the RC6432F4872CS (Active status) is the preferred selection. The ERJ-1TNF4872U is suitable for replacement applications and legacy system support where supply confirmation is obtained.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The ERJ-1TNF4872U includes AEC-Q200 automotive qualification, indicating enhanced reliability testing for automotive applications. The RC6432F4872CS is specified as moisture resistant. Both certifications are compatible with general industrial and automotive use; neither restricts substitution.

Q: Do dimensional differences affect PCB layout?

A: No. The dimensional variations (RC6432F4872CS: 6.30mm x 3.20mm; ERJ-1TNF4872U: 6.40mm x 3.20mm) are within standard 2512 package tolerances. Both components use identical PCB footprints and termination spacing. Height differences (0.66mm vs. 0.70mm) do not affect assembly or clearance in standard applications.

Q: What parameters must match for substitution eligibility?

A: Substitution requires identical resistance value (48.7 kOhms), tolerance (±1%), power rating (1W), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). RoHS and REACH compliance status must be equivalent or superior. Moisture Sensitivity Level must be 1 (Unlimited) or equivalent.
