RC6432F4751CS Equivalent & Substitute Parts

Part Overview

The RC6432F4751CS is a 4.75 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The component maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

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.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4751CS is determined by strict alignment of the following critical parameters:

Electrical Specifications:

• Resistance value: 4.75 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Specifications:

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance & Environmental:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• Thick film composition

The substitute part CRCW25124K75FKEG meets all these criteria and qualifies as a direct equivalent. Both components share identical electrical performance characteristics, package dimensions, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F4751CS and CRCW25124K75FKEG are Active products with identical electrical and mechanical specifications. Selection between these components is based on availability, packaging format, and application-specific requirements.

The CRCW25124K75FKEG is supplied in Tape & Reel (TR) packaging and carries AEC-Q200 automotive qualification. The RC6432F4751CS features moisture-resistant construction. Both components satisfy ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications.

Physical dimensions show negligible variation: RC6432F4751CS measures 0.248" L × 0.126" W with 0.026" maximum seated height, while CRCW25124K75FKEG measures 0.248" L × 0.124" W with 0.028" maximum seated height. These dimensional differences remain within standard PCB footprint tolerances for 2512 package format.

Frequently Asked Questions (FAQ)

Q: Can CRCW25124K75FKEG directly replace RC6432F4751CS in existing designs?

A: Yes. Both components share identical resistance value (4.75 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 2512 package format. Electrical and mechanical compatibility is confirmed.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Samsung Electro-Mechanics vs. Vishay Dale), packaging format (bulk vs. Tape & Reel), and additional qualification (CRCW25124K75FKEG carries AEC-Q200 automotive rating). Electrical performance and compliance status are identical.

Q: Are the physical dimensions identical?

A: Dimensions are functionally equivalent for PCB placement. RC6432F4751CS: 6.30mm L × 3.20mm W × 0.66mm H (max). CRCW25124K75FKEG: 6.30mm L × 3.15mm W × 0.70mm H (max). Variations fall within standard 2512 footprint tolerances.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both RC6432F4751CS and CRCW25124K75FKEG are ROHS3 compliant and REACH unaffected, suitable for regulated markets and applications requiring environmental compliance.

Q: Which part should be selected for automotive applications?

A: CRCW25124K75FKEG carries AEC-Q200 automotive qualification. For non-automotive applications, either component is acceptable based on availability and packaging requirements.

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

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. Both components can be stored and handled without time-sensitive moisture sensitivity constraints, simplifying inventory management and supply chain logistics.
