RC6432F6342CS Equivalent & Substitute Parts

Part Overview

The RC6432F6342CS is a 63.4 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is currently in active production status. Substitute parts are identified based on matching electrical specifications, package dimensions, and environmental compliance requirements. Alternative components may be necessary due to supply chain considerations, inventory availability, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6342CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (63.4 kOhms), tolerance (±1%), and power rating (1W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Package Compatibility: The 2512 (6432 Metric) package designation is mandatory. Physical dimensions and termination count (2 terminations) must align with PCB layout requirements.

Environmental & Compliance Standards: RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status ensure regulatory alignment. Additional certifications such as AEC-Q200 may be present in substitute parts but do not disqualify substitution.

Product Status Consideration: While the main part is Active, substitute parts may carry different product status designations. This does not affect electrical or mechanical compatibility but may influence long-term availability planning.

Parameter Comparison

Engineering Selection Recommendations

RC6432F6342CS (Samsung Electro-Mechanics): This component is designated as Active and represents the primary selection for new designs. It provides standard moisture-resistant thick film construction with full compliance to ROHS3 and REACH requirements. Current inventory of 983 pieces supports immediate procurement.

ERJ-1TNF6342U (Panasonic Electronic Components): This substitute part meets all electrical and mechanical specifications with identical resistance, tolerance, power rating, and temperature characteristics. The component carries Automotive AEC-Q200 certification, indicating qualification for automotive-grade applications. However, the product status is designated as "Not For New Designs," which indicates this part is in mature or declining production phase. Selection of this substitute should be limited to applications requiring automotive qualification or where existing supply chain relationships necessitate its use. Inventory availability is higher at 9,719 pieces.

Dimensional Tolerance: Minor dimensional variations exist between the two parts. The Samsung part measures 6.30mm x 3.20mm with 0.66mm maximum seated height, while the Panasonic part measures 6.40mm x 3.20mm with 0.70mm maximum seated height. These differences remain within standard PCB layout tolerances for 2512 package footprints and do not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6342U be used as a direct replacement for RC6432F6342CS?

A: Yes. Both components share identical electrical specifications (63.4 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and package designation (2512 / 6432 Metric). Minor dimensional variations (0.1mm length difference, 0.04mm height difference) fall within standard PCB layout tolerances and do not affect circuit performance or board assembly.

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

A: This designation indicates the ERJ-1TNF6342U is in a mature production phase with potential for future discontinuation. For new product development, the Samsung RC6432F6342CS (Active status) is the recommended primary selection. The Panasonic part remains suitable for replacement, repair, or applications where automotive AEC-Q200 certification is specifically required.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). The Panasonic part includes additional Automotive AEC-Q200 certification, which is not present in the Samsung part. This certification is beneficial for automotive applications but is not required for general industrial or consumer electronics use.

Q: What packaging formats are available?

A: The Samsung RC6432F6342CS is supplied in standard packaging format. The Panasonic ERJ-1TNF6342U is available in Tape & Reel (TR) format, which is standard for high-volume automated assembly operations.

Q: How do the physical dimensions affect PCB layout?

A: Both parts conform to the 2512 (6432 Metric) package standard. The maximum dimensional differences (0.1mm in length, 0.04mm in height) are negligible for standard PCB footprint design. Existing 2512 footprints accommodate both components without modification.
