RC6432F5232CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F5232CS is a 52.3 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 ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 1039 units in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, package size, and operating temperature range. Alternative sources become necessary for supply chain continuity, design flexibility, or when the primary manufacturer discontinues production.

Engineering Selection Recommendations

Primary Part: RC6432F5232CS (Samsung Electro-Mechanics)

Status: Active production. Recommended for new designs requiring Samsung sourcing or existing supply chain integration. 1039 units currently in stock.

Substitute Part: ERJ-1TNF5232U (Panasonic Electronic Components)

Status: Not For New Designs. This part is suitable for replacement in existing applications or when Samsung supply is unavailable. The Panasonic ERJ-1TN series includes automotive AEC-Q200 qualification, providing additional reliability certification for automotive applications. 2644 units currently in stock.

Selection Criteria:

Use RC6432F5232CS for new designs unless automotive AEC-Q200 qualification is required
Use ERJ-1TNF5232U as a direct substitute in existing designs or when Samsung supply is constrained
Both parts are ROHS3 compliant and suitable for -55°C to 155°C operating environments
Dimensional compatibility is confirmed; PCB layout modifications are not required
Packaging format differs (Samsung: standard; Panasonic: Tape & Reel), which may affect procurement and assembly processes

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF5232U replace RC6432F5232CS in existing circuit designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (52.3 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Package dimensions are compatible for standard PCB footprints.

Q: What is the difference between the two parts?

A: The primary differences are manufacturer (Samsung versus Panasonic), product status (Active versus Not For New Designs), and additional automotive qualification (ERJ-1TNF5232U includes AEC-Q200 certification). Electrical and mechanical specifications are equivalent.

Q: Are there packaging differences?

A: Yes. RC6432F5232CS is supplied in standard packaging, while ERJ-1TNF5232U is supplied in Tape & Reel (TR) format. This affects procurement, storage, and assembly processes but does not impact component performance.

Q: Is the slight dimensional variation (6.30mm vs 6.40mm length) a concern?

A: No. The 0.10mm difference in length is within standard PCB design tolerances for 2512 package footprints. No layout modifications are required.

Q: Can I use these parts in automotive applications?

A: RC6432F5232CS is suitable for automotive use based on operating temperature range and ROHS3 compliance. ERJ-1TNF5232U includes explicit AEC-Q200 automotive qualification, providing additional reliability assurance for automotive-grade applications.

Q: What is the MSL 1 rating significance?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts share this rating, simplifying inventory management.
