RC6432F4322CS Equivalent & Substitute Parts

Part Overview

The RC6432F4322CS is a 43.2 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component is designed for general-purpose applications requiring precision resistive elements with moderate power dissipation. The part maintains Active product status with 740 units currently in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as automotive qualification, or when alternative sourcing strategies are implemented to optimize procurement and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4322CS is determined by strict equivalence across the following parameters:

• Resistance value: 43.2 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The ERJ-1TNF4322U from Panasonic Electronic Components meets all electrical and mechanical substitution criteria. Minor dimensional variations within the 2512 package specification are permissible. The Panasonic part carries automotive AEC-Q200 qualification, which represents an additional certification beyond the base requirements and does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The RC6432F4322CS maintains Active product status and is the primary selection for new designs. The ERJ-1TNF4322U is electrically and mechanically equivalent but carries a "Not For New Designs" status, indicating that Panasonic has transitioned this part to end-of-life management. The Panasonic part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Selection between these parts should be based on supply availability, procurement lead times, and application-specific requirements. The Samsung part is preferred for ongoing production due to its Active status. The Panasonic part remains a valid substitute for existing designs or applications where automotive qualification is beneficial.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF4322U be used as a direct replacement for RC6432F4322CS?

A: Yes. Both parts share identical electrical specifications (43.2 kOhms, ±1%, 1W), identical package designation (2512), and identical environmental ratings. Physical dimensions vary slightly within package tolerance, and both are suitable for PCB assembly without modification.

Q: What does "Not For New Designs" mean for the Panasonic part?

A: This status indicates that Panasonic has discontinued active development and marketing of the ERJ-1TNF4322U. Existing inventory may remain available, but the manufacturer does not recommend this part for new product development. The RC6432F4322CS is the appropriate choice for new designs.

Q: Are there dimensional differences between these parts?

A: Both parts conform to the 2512 (6432 Metric) package specification. The RC6432F4322CS has maximum seated height of 0.026" (0.66mm) with dimensions 0.248" L x 0.126" W. The ERJ-1TNF4322U has maximum seated height of 0.028" (0.70mm) with dimensions 0.252" L x 0.126" W. These variations remain within standard 2512 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Does the AEC-Q200 rating on the Panasonic part restrict its use?

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing. A part with AEC-Q200 qualification can be used in any application, including non-automotive designs. It represents a superset of standard reliability requirements.

Q: What is the moisture sensitivity level, and why is it important?

A: Both parts have MSL 1 (Unlimited), meaning they have unlimited shelf life and require no special moisture control during storage or handling. This is the least restrictive moisture sensitivity classification and simplifies inventory management.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC6432F4322CS and ERJ-1TNF4322U are ROHS3 Compliant, meeting current environmental and hazardous substance restrictions for electronic components.
