RC6432F3162CS Equivalent & Substitute Parts

Part Overview

The RC6432F3162CS is a 31.6 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. 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 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, 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 RC6432F3162CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 31.6 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Critical Mechanical Parameters:

• Package type: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Both identified substitute parts meet all critical parameters. The CRCW251231K6FKEG (Vishay Dale) and RMCF2512FT31K6 (Stackpole Electronics Inc) are functionally equivalent to the RC6432F3162CS and are qualified for direct substitution in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RC6432F3162CS, CRCW251231K6FKEG, and RMCF2512FT31K6—are active production components with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on:

Availability: RMCF2512FT31K6 (Stackpole) has the highest inventory at 8,836 pieces, followed by CRCW251231K6FKEG (Vishay Dale) at 3,488 pieces, and RC6432F3162CS (Samsung) at 767 pieces.

Automotive Qualification: CRCW251231K6FKEG and RMCF2512FT31K6 both carry AEC-Q200 automotive qualification ratings, making them suitable for automotive and high-reliability applications. The RC6432F3162CS does not specify AEC-Q200 qualification.

Packaging: RC6432F3162CS and RMCF2512FT31K6 share identical dimensions (0.248" L x 0.126" W / 6.30mm x 3.20mm). CRCW251231K6FKEG has a slightly narrower width (0.124" W / 3.15mm). All three have compatible height specifications for standard PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can CRCW251231K6FKEG or RMCF2512FT31K6 be used as direct replacements for RC6432F3162CS?

A: Yes. Both substitute parts meet all critical electrical parameters (31.6 kOhms, ±1% tolerance, 1W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range), mechanical specifications (2512 package, thick film composition), and compliance requirements (ROHS3, MSL 1). They are functionally equivalent and suitable for direct substitution.

Q: What is the difference between the three parts?

A: The electrical and mechanical specifications are identical. The primary differences are manufacturer (Samsung, Vishay Dale, Stackpole), packaging format (bulk vs. Tape & Reel), inventory availability, and automotive qualification status. CRCW251231K6FKEG and RMCF2512FT31K6 include AEC-Q200 automotive qualification; RC6432F3162CS does not specify this rating.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: RC6432F3162CS and RMCF2512FT31K6 have identical dimensions (6.30mm L x 3.20mm W). CRCW251231K6FKEG is slightly narrower (6.30mm L x 3.15mm W). All three have compatible maximum seated heights (0.66mm to 0.70mm). For standard PCB layouts, all three are mechanically compatible.

Q: Which part should be selected for automotive applications?

A: CRCW251231K6FKEG (Vishay Dale) and RMCF2512FT31K6 (Stackpole Electronics Inc) both carry AEC-Q200 automotive qualification. Either part is suitable for automotive-grade applications. RC6432F3162CS does not specify AEC-Q200 qualification.

Q: What is the moisture sensitivity level, and why does it matter?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying supply chain and assembly processes.

Q: Are all three parts RoHS compliant?

A: Yes. RC6432F3162CS, CRCW251231K6FKEG, and RMCF2512FT31K6 are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and global markets.
