RC6432F2431CS Equivalent & Substitute Parts

Part Overview

The RC6432F2431CS is a 2.43 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 700 pieces available in inventory.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements shift toward automotive-qualified components, or when alternative sourcing strategies are implemented to optimize procurement costs and lead times while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2431CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (2.43 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical. Operating temperature range must encompass or equal -55°C to 155°C.

Mechanical Parameters: Package designation must be 2512 (6432 Metric) with two terminations. Physical dimensions and height specifications must be compatible with the original footprint.

Material & Composition: Thick film construction is required. Moisture resistance characteristics must meet or exceed the original specification.

Compliance & Certification: RoHS3 compliance and MSL 1 rating are mandatory. REACH unaffected status must be maintained.

The identified substitute part ERJ-1TNF2431U from Panasonic Electronic Components meets all electrical and mechanical equivalence criteria. This part carries additional automotive AEC-Q200 qualification, which represents an enhancement rather than a deviation from the base specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC6432F2431CS remains the preferred choice for new designs due to its active product status and direct availability from the original manufacturer Samsung Electro-Mechanics.

Substitute Selection: ERJ-1TNF2431U from Panasonic Electronic Components is electrically and mechanically equivalent and qualifies as a direct substitute. This part carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. However, the product status is listed as "Not For New Designs," indicating that Panasonic may be phasing this part from active production.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) format, whereas the primary part is supplied in bulk packaging. This difference affects procurement logistics and assembly processes but does not impact electrical or mechanical performance.

Compliance Verification: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings, ensuring regulatory equivalence across supply chain transitions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2431U be used as a direct replacement for RC6432F2431CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (2.43 kOhms ±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 2512 package format. The primary difference is packaging format (Tape & Reel versus bulk) and the addition of AEC-Q200 automotive qualification on the Panasonic part.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF2431U?

A: This designation indicates that Panasonic is not recommending this specific part number for incorporation into newly developed products. However, it remains functionally equivalent and available in inventory. This status does not affect compatibility or performance in existing applications.

Q: Are there dimensional differences between these two parts?

A: Minor dimensional variations exist. The RC6432F2431CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with a maximum seated height of 0.026" (0.66mm). The ERJ-1TNF2431U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with a maximum seated height of 0.028" (0.70mm). These differences are within typical PCB footprint tolerances for 2512 package components and do not require layout modifications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and high-volume production. The electrical and mechanical properties of the component are identical; only the delivery format differs.
