RC6432F5621CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F5621CS is a 5.62 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 with 669 units in stock. Substitute parts are identified for applications requiring alternative sourcing, inventory availability, or specific automotive certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F5621CS is determined by strict equivalence across the following parameters:

• Resistance Value: 5.62 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Termination Count: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances and differences in packaging format (Tape & Reel vs. bulk) do not affect functional substitution. Automotive AEC-Q200 certification is an additional feature present in substitute parts but not required for substitution.

Parameter Comparison

Engineering Selection Recommendations

CRCW25125K62FKEG (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains active product status, carries AEC-Q200 automotive certification, and has the highest inventory availability (3053 units). It is suitable for both commercial and automotive applications requiring the specified electrical and thermal characteristics.

ERJ-1TNF5621U (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" status. This part is available in high inventory (4794 units) and includes AEC-Q200 certification. Use this part only for legacy system maintenance, repair, or applications where design freeze requirements permit non-active components.

RC6432F5621CS (Samsung Electro-Mechanics) remains the original specification. Select this part when Samsung sourcing is contractually required or when the specific moisture-resistant thick film formulation is mandated by design documentation.

Frequently Asked Questions (FAQ)

Q: Can CRCW25125K62FKEG replace RC6432F5621CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 5.62 kOhms ±1%, 1W power rating, 2512 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The CRCW part includes additional AEC-Q200 automotive certification, which does not restrict its use in non-automotive applications.

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

A: Tape & Reel (TR) packaging is used for automated assembly processes and high-volume production. Bulk packaging is used for manual assembly or lower-volume applications. Both formats contain identical components; packaging selection depends on manufacturing process requirements, not electrical performance.

Q: Why is ERJ-1TNF5621U marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and support for this part number. Existing inventory remains available for maintenance and repair of legacy systems. New product designs should specify CRCW25125K62FKEG or RC6432F5621CS.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. RC6432F5621CS: 6.30mm L × 3.20mm W × 0.66mm H (max). CRCW25125K62FKEG: 6.30mm L × 3.15mm W × 0.70mm H (max). ERJ-1TNF5621U: 6.40mm L × 3.20mm W × 0.70mm H (max). These variations do not affect PCB layout or functional performance in standard 2512 footprints.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. RC6432F5621CS, CRCW25125K62FKEG, and ERJ-1TNF5621U are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH unaffected and classified as EAR99 for export purposes.

Q: Which part should be selected for automotive applications?

A: CRCW25125K62FKEG is recommended for automotive applications due to active product status and AEC-Q200 certification. ERJ-1TNF5621U also carries AEC-Q200 certification but is not recommended for new automotive designs due to its "Not For New Designs" status.
