RC6432F4222CS 42.2kΩ 1W Chip Resistor 2512 Equivalent & Substitute Parts

Part Overview

The RC6432F4222CS is a 42.2 kOhms ±1% 1W thick film chip resistor in 2512 (6432 metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with moisture resistant characteristics and unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, suitable for general industrial and commercial applications requiring precision resistive elements with moderate power dissipation.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type, dimensions, termination count), and environmental operating parameters. Substitute components maintain identical or functionally equivalent performance characteristics within the defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4222CS is determined by strict equivalence across the following parameter categories:

Electrical Parameters (Critical): Resistance value must be 42.2 kOhms. Tolerance must be ±1%. Power rating must be 1W. Temperature coefficient must be ±100ppm/°C. Operating temperature range must span -55°C to 155°C minimum.

Mechanical Parameters (Critical): Package designation must be 2512 (6432 metric). Number of terminations must be 2. Physical dimensions must be compatible with standard 2512 footprints (length 6.30mm ±tolerance, width 3.15-3.20mm, height ≤0.70mm seated maximum).

Material & Composition (Important): Composition must be thick film. This ensures equivalent electrical behavior and frequency response characteristics.

Compliance Parameters (Important): RoHS3 compliance required. MSL rating of 1 (unlimited) required. REACH unaffected status required. ECCN and HTSUS classifications must align with industrial component standards.

Product Status Consideration: Active status parts are preferred for new designs. Parts with "Not For New Designs" status are functionally equivalent but may have limited future availability.

Identified substitute parts meeting all critical parameters: CRCW251242K2FKEG (Vishay Dale), ERJ-1TNF4222U (Panasonic Electronic Components).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - RC6432F4222CS (Samsung Electro-Mechanics): This is the original specified component with Active product status, indicating full manufacturer support and continued availability. Recommended for new designs and applications requiring long-term supply chain stability.

First Substitute - CRCW251242K2FKEG (Vishay Dale): This component maintains Active product status with identical electrical specifications and package compatibility. The Vishay Dale CRCW series includes automotive AEC-Q200 qualification, providing enhanced reliability documentation. Physical dimensions are equivalent within standard PCB assembly tolerances. Tape & Reel packaging is standard for automated assembly operations. This substitute is suitable for direct replacement in both new designs and existing production.

Second Substitute - ERJ-1TNF4222U (Panasonic Electronic Components): This component provides electrical and mechanical equivalence with identical resistance, tolerance, power rating, and operating temperature range. Panasonic ERJ-1TN series includes automotive AEC-Q200 qualification. However, this part carries "Not For New Designs" product status, indicating the manufacturer is phasing out this component line. This substitute is appropriate only for maintenance, repair, and obsolescence mitigation of existing products. The physical dimension variance (length 6.40mm vs. 6.30mm) remains within standard 2512 package tolerances and does not affect PCB footprint compatibility.

Compliance Verification: All three components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, confirming regulatory and environmental compatibility across all options.

Frequently Asked Questions (FAQ)

Q: Can CRCW251242K2FKEG be used as a direct replacement for RC6432F4222CS?

A: Yes. Both components share identical electrical specifications (42.2 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), identical package type (2512/6432 metric), and equivalent physical dimensions. CRCW251242K2FKEG maintains Active product status and ROHS3 compliance. Direct substitution is supported without circuit redesign.

Q: What is the difference between the Samsung RC6432F4222CS and Vishay CRCW251242K2FKEG?

A: The primary differences are manufacturer and packaging format. Samsung RC6432F4222CS is specified with standard packaging (-), while Vishay CRCW251242K2FKEG is supplied in Tape & Reel (TR) format for automated assembly. Vishay's component includes automotive AEC-Q200 qualification. Electrical performance and package footprint are equivalent.

Q: Why is ERJ-1TNF4222U marked "Not For New Designs"?

A: "Not For New Designs" status indicates that Panasonic is discontinuing this product line. While the component is functionally equivalent and currently in stock, the manufacturer recommends using alternative parts for new product development to ensure long-term availability. This part is suitable for sustaining production of existing designs.

Q: Are there dimensional compatibility issues between these three parts?

A: All three components conform to the 2512 (6432 metric) package standard. Minor dimensional variations exist: RC6432F4222CS and CRCW251242K2FKEG have 6.30mm length, while ERJ-1TNF4222U has 6.40mm length. These variations fall within standard PCB footprint tolerances and do not affect assembly or electrical performance. Height differences (0.66mm to 0.70mm seated maximum) are similarly within acceptable assembly clearance ranges.

Q: Can these parts be used in automotive applications?

A: CRCW251242K2FKEG and ERJ-1TNF4222U both carry automotive AEC-Q200 qualification, confirming suitability for automotive applications. RC6432F4222CS does not specify AEC-Q200 qualification; automotive application suitability should be confirmed with Samsung Electro-Mechanics for specific use cases.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture-controlled storage or handling. These parts can be stored under standard industrial conditions without desiccant packaging or time-limited shelf life restrictions.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC6432F4222CS, CRCW251242K2FKEG, and ERJ-1TNF4222U are all ROHS3 compliant and REACH unaffected, confirming compliance with current EU environmental and hazardous substance regulations.
