RC6432F2433CS Equivalent & Substitute Parts

Part Overview

The RC6432F2433CS is a 243 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. The part is currently in active production status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F2433CS is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (243 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical
• Package Compatibility: 2512 (6432 Metric) package ensures mechanical and footprint compatibility
• Composition: Thick film construction maintains performance characteristics
• Environmental Ratings: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL 1 rating ensure functional equivalence
• Termination Configuration: 2-terminal configuration is required

The identified substitute ERJ-1TNF2433U meets all these criteria. Dimensional variations within tolerance (length 6.40mm vs. 6.30mm, height 0.70mm vs. 0.66mm) remain within acceptable PCB assembly parameters for the 2512 package class.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC6432F2433CS (Samsung Electro-Mechanics) is the recommended choice for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability.

Substitute Selection: ERJ-1TNF2433U (Panasonic Electronic Components) provides electrical and mechanical equivalence with identical resistance, tolerance, power rating, temperature coefficient, and operating range. This substitute is suitable for applications where Samsung supply is unavailable. However, the Panasonic part carries "Not For New Designs" status, indicating it is maintained for legacy support only. The automotive AEC-Q200 qualification of the Panasonic part provides additional reliability assurance for applications requiring automotive-grade components.

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2433U be used as a direct replacement for RC6432F2433CS?

A: Yes. Both parts share identical electrical specifications (243 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 2512 (6432 Metric) format. Dimensional differences (length 6.40mm vs. 6.30mm, height 0.70mm vs. 0.66mm) fall within standard PCB assembly tolerances for this package class and do not affect functional compatibility.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This designation indicates that Panasonic has discontinued active development and new feature support for the ERJ-1TNF2433U. The part remains available for existing applications and legacy designs but should not be selected for new product development. The RC6432F2433CS, with active status, is the preferred choice for new designs.

Q: Are there packaging differences between these parts?

A: Yes. The RC6432F2433CS is supplied in standard packaging, while the ERJ-1TNF2433U is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical performance once mounted on the PCB.

Q: Do both parts meet automotive standards?

A: The Panasonic ERJ-1TNF2433U carries AEC-Q200 automotive qualification. The Samsung RC6432F2433CS does not list automotive certification in the provided specifications. For automotive applications, the Panasonic part provides documented compliance.

Q: What are the compliance certifications for both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 under ECCN regulations. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
