RC6432F1403CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1403CS is a 140 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and maintains ROHS3 compliance with MSL 1 rating. The part is currently in active production status with 827 pieces available in inventory. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1403CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 140 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Requirements:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The CRCW2512140KFKEG manufactured by Vishay Dale satisfies all critical parameters and is therefore classified as a direct equivalent substitute. Both components share identical electrical specifications, mechanical dimensions within acceptable tolerances, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1403CS (Samsung Electro-Mechanics)

Selection criteria: Primary choice when Samsung component availability and supply chain continuity are prioritized. Active production status with 827 units in current inventory. Moisture-resistant thick film construction with MSL 1 rating supports unlimited shelf life storage. ROHS3 and REACH compliance certifications meet standard industrial and commercial application requirements.

CRCW2512140KFKEG (Vishay Dale)

Selection criteria: Direct substitute when Vishay Dale supply chain or automotive-qualified components are required. AEC-Q200 automotive qualification rating provides additional reliability assurance for automotive and harsh-environment applications. Significantly higher inventory availability (231,877 units) supports high-volume production requirements. Tape & Reel packaging format accommodates automated assembly processes. Mechanical dimensions remain within acceptable tolerance for PCB footprint compatibility.

Both components satisfy identical electrical performance specifications and compliance requirements. Selection between them depends on supply chain strategy, packaging format requirements, and application-specific certifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512140KFKEG replace RC6432F1403CS in existing circuit designs?

A: Yes. Both components share identical electrical specifications (140 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical package format (2512/6432 Metric). Mechanical dimension variations (width 3.20mm vs 3.15mm, height 0.66mm vs 0.70mm) remain within standard PCB footprint tolerances and do not affect circuit functionality or board layout compatibility.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW2512140KFKEG carries this certification, indicating compliance with automotive reliability and environmental stress testing requirements. This qualification is not present on the Samsung RC6432F1403CS. Selection of the AEC-Q200 qualified part is necessary only when automotive application standards are specified in design requirements.

Q: Are packaging format differences between the two parts significant?

A: The RC6432F1403CS is supplied in standard packaging format. The CRCW2512140KFKEG is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly equipment. Tape & Reel packaging does not affect component electrical or mechanical performance; it only impacts manufacturing process compatibility and handling procedures.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings. Compliance certifications are equivalent across both parts.

Q: What determines whether a part qualifies as a substitute?

A: Substitution eligibility requires matching of all critical parameters: resistance value (140 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), package format (2512 Metric), composition (thick film), and compliance certifications (ROHS3, MSL 1, REACH unaffected). Mechanical dimension variations within standard PCB footprint tolerances do not disqualify substitution.
