RC6432F1621CS Equivalent & Substitute Parts

Part Overview

The RC6432F1621CS is a 1.62 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor features moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources provide equivalent functional performance for applications requiring component interchangeability.

Key Parameters

Substitute Part Grouping Explanation

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

• Resistance Value: 1.62 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package Format: 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 and are therefore electrically and mechanically interchangeable with the RC6432F1621CS in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical electrical and mechanical specifications within the parameters provided. Selection between the RC6432F1621CS, CRCW25121K62FKEG, and RMCF2512FT1K62 is based on the following factors:

RC6432F1621CS (Samsung Electro-Mechanics): Features moisture-resistant construction. Active product status. ROHS3 compliant with unlimited MSL rating.

CRCW25121K62FKEG (Vishay Dale): Includes automotive AEC-Q200 qualification. Tape & Reel packaging. Active product status. ROHS3 compliant with unlimited MSL rating. Dimensions: 0.248" L x 0.124" W (6.30mm x 3.15mm), Height 0.028" (0.70mm).

RMCF2512FT1K62 (Stackpole Electronics Inc): Includes automotive AEC-Q200 qualification. Tape & Reel packaging. Active product status. ROHS3 compliant with unlimited MSL rating. Dimensions: 0.248" L x 0.126" W (6.30mm x 3.20mm), Height 0.028" (0.70mm).

All parts are suitable for direct substitution in applications requiring 1.62 kOhms ±1% 1W thick film chip resistors in 2512 package format. Automotive-grade applications benefit from the AEC-Q200 qualified alternatives.

Frequently Asked Questions (FAQ)

Q: Can CRCW25121K62FKEG replace RC6432F1621CS in any application?

A: Yes. Both parts share identical electrical specifications (1.62 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2512 package, 2 terminations). Dimensional variations are within standard manufacturing tolerances for the 2512 package format.

Q: What is the difference between the Samsung and Stackpole versions?

A: The primary difference is manufacturer and qualification level. RMCF2512FT1K62 includes automotive AEC-Q200 qualification, while RC6432F1621CS emphasizes moisture-resistant construction. Electrical and mechanical parameters are identical.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: Does packaging format affect substitution?

A: The RC6432F1621CS is supplied in standard packaging, while CRCW25121K62FKEG and RMCF2512FT1K62 are supplied in Tape & Reel format. Both formats are compatible with the same 2512 package footprint and PCB assembly processes.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, with EAR99 export classification.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements prior to soldering. All three parts share this rating.
