Parameter Comparison

Engineering Selection Recommendations

All three parts—RC6432F31R6CS, CRCW251231R6FKEG, and RMCF2512FT31R6—are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability, packaging format, and application-specific requirements:

RC6432F31R6CS (Samsung Electro-Mechanics): Primary choice when Samsung sourcing is preferred. Moisture-resistant thick film construction. 900 pieces in current inventory.

CRCW251231R6FKEG (Vishay Dale): Qualified for automotive applications with AEC-Q200 certification. Supplied in Tape & Reel packaging. 8257 pieces in current inventory. Dimensions: 0.248" L x 0.124" W (6.30mm x 3.15mm), Height 0.028" (0.70mm).

RMCF2512FT31R6 (Stackpole Electronics Inc): Qualified for automotive applications with AEC-Q200 certification. Supplied in Tape & Reel packaging. 4353 pieces in current inventory. Dimensions: 0.248" L x 0.126" W (6.30mm x 3.20mm), Height 0.028" (0.70mm).

All parts comply with ROHS3 and REACH requirements. Substitution is valid across all three parts without electrical or mechanical compromise.

Frequently Asked Questions (FAQ)

Q: Can CRCW251231R6FKEG replace RC6432F31R6CS in any application?

A: Yes. Both parts share identical electrical specifications (31.6 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), identical package type (2512), and equivalent compliance status (ROHS3, REACH Unaffected, MSL 1). The primary difference is packaging format (Tape & Reel for CRCW vs. standard for RC) and minor dimensional variation in width (3.15mm vs. 3.20mm) and height (0.70mm vs. 0.66mm), which remain within 2512 footprint tolerance.

Q: What is the difference between the Vishay and Stackpole substitute parts?

A: CRCW251231R6FKEG and RMCF2512FT31R6 are functionally equivalent. Both are AEC-Q200 qualified thick film resistors with identical electrical parameters. Dimensional differences are minimal: Vishay width is 3.15mm vs. Stackpole 3.20mm; both have 0.70mm seated height. Both are supplied in Tape & Reel format. Selection depends on supplier availability and inventory levels.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW251231R6FKEG and RMCF2512FT31R6 both carry AEC-Q200 automotive qualification. RC6432F31R6CS does not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, use CRCW251231R6FKEG or RMCF2512FT31R6.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All three parts have MSL 1 rating, meaning they can be stored and handled without special moisture-protective packaging or baking procedures.

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

A: All three parts conform to the 2512 (6432 Metric) package standard. Seated heights vary slightly (0.66mm for RC6432F31R6CS vs. 0.70mm for both substitutes), and width varies minimally (3.20mm vs. 3.15mm). These variations remain within standard 2512 package tolerances and do not affect PCB footprint compatibility.

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

A: Tape & Reel packaging is used for automated assembly processes and high-volume production. Standard packaging may refer to bulk or alternative formats. Both packaging types contain identical components; the difference is in handling and assembly method. Verify your assembly process requirements before selecting based on packaging format.
