Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F2743CS is determined by strict equivalence across the following parameters: resistance value (274 kOhms), tolerance (±1%), power rating (1W), package type (2512 / 6432 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts match these core electrical and mechanical specifications. Composition remains thick film across all alternatives. RoHS3 compliance and MSL 1 rating are maintained. Substitute parts are grouped by manufacturer and product status, with variations in packaging format (Tape & Reel versus Cut Tape) and optional automotive AEC-Q200 certification noted where applicable.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512274KFKEG (Vishay Dale) is suitable for applications requiring automotive-grade components with AEC-Q200 certification. This part maintains Active product status and is available in Tape & Reel packaging format. Electrical and thermal specifications are fully equivalent to the RC6432F2743CS.

RMCF2512FT274K (Stackpole Electronics Inc) is suitable for high-volume production environments. This part maintains Active product status, carries AEC-Q200 automotive certification, and is available in Cut Tape packaging. Dimensional and electrical specifications are equivalent to the RC6432F2743CS.

ERJ-1TNF2743U (Panasonic Electronic Components) carries AEC-Q200 automotive certification but is designated as Not For New Designs. This part is suitable only for legacy system maintenance or replacement applications where existing design qualification has been established. Electrical specifications remain equivalent.

All three substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical parameters (274 kOhms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C operating range).

Frequently Asked Questions (FAQ)

Q: Can CRCW2512274KFKEG directly replace RC6432F2743CS in existing designs?

A: Yes. Both parts share identical electrical specifications (274 kOhms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C), package type (2512 / 6432 Metric), and compliance ratings (ROHS3, MSL 1). Dimensional variations are within standard PCB layout tolerances. The primary difference is packaging format (Tape & Reel versus bulk) and optional AEC-Q200 automotive certification on the Vishay part.

Q: What is the difference between the RC6432F2743CS and RMCF2512FT274K?

A: Both parts are electrically and thermally equivalent with identical resistance (274 kOhms ±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The RC6432F2743CS is manufactured by Samsung Electro-Mechanics with moisture resistant features. The RMCF2512FT274K is manufactured by Stackpole Electronics Inc with AEC-Q200 automotive certification. Packaging differs (bulk versus Cut Tape). Both maintain ROHS3 compliance and MSL 1 rating.

Q: Why is ERJ-1TNF2743U marked as "Not For New Designs"?

A: The ERJ-1TNF2743U carries a "Not For New Designs" product status designation from Panasonic Electronic Components. This indicates the part is in mature or declining production phase. While electrically and mechanically equivalent to the RC6432F2743CS, it is recommended for legacy system support only. For new designs, CRCW2512274KFKEG or RMCF2512FT274K are preferred alternatives with Active product status.

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

A: Dimensional variations exist within standard tolerances. The RC6432F2743CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. Substitute parts measure 0.248-0.252" L x 0.124-0.126" W with 0.028" max height. These variations fall within standard PCB design margins for 2512 package footprints and do not affect functional interchangeability.

Q: Which substitute part offers the best inventory availability?

A: RMCF2512FT274K (Stackpole Electronics Inc) shows the highest inventory level at 16,545 pieces. CRCW2512274KFKEG (Vishay Dale) has 2,641 pieces available. ERJ-1TNF2743U (Panasonic) has 3,333 pieces available. Inventory levels are subject to change and should be verified with current supplier data.

Q: Do all substitute parts meet automotive specifications?

A: CRCW2512274KFKEG and RMCF2512FT274K both carry AEC-Q200 automotive certification. The RC6432F2743CS does not specify automotive rating. ERJ-1TNF2743U carries AEC-Q200 but is marked "Not For New Designs." For automotive applications requiring AEC-Q200 compliance, CRCW2512274KFKEG or RMCF2512FT274K are appropriate selections.
