Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F19R1CS are qualified based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 19.1 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match or Be Compatible):

• Package type: 2512 (6432 Metric)
• Physical dimensions within acceptable tolerance
• Two terminations

Compliance & Environmental Parameters:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)
• Thick film composition

Two substitute parts meet these criteria: ERJ-1TNF19R1U (Panasonic Electronic Components) and RMCF2512FT19R1 (Stackpole Electronics Inc). Both components satisfy all electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RMCF2512FT19R1 (Stackpole Electronics Inc)

The RMCF2512FT19R1 is the preferred substitute for the RC6432F19R1CS. Both components are in active production status, ensuring long-term availability and supply chain stability. The Stackpole part maintains identical electrical specifications and is housed in the same 2512 package. The component carries AEC-Q200 automotive qualification, providing additional reliability assurance for demanding applications. Mechanical dimensions are compatible with the original part, with a maximum seated height of 0.028" (0.70mm) compared to the original 0.026" (0.66mm), which remains within acceptable PCB assembly tolerances.

Secondary Substitute: ERJ-1TNF19R1U (Panasonic Electronic Components)

The ERJ-1TNF19R1U meets all electrical and mechanical requirements for substitution. However, this part carries a "Not For New Designs" product status designation, indicating that Panasonic has discontinued active development for this component. While existing inventory of 3571 units is available, this part should be selected only when RMCF2512FT19R1 is unavailable. The ERJ-1TNF19R1U is supplied in Tape & Reel packaging, whereas the primary substitute is available in Cut Tape format.

Both substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the environmental and compliance profile of the original RC6432F19R1CS.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF19R1U be used as a direct replacement for RC6432F19R1CS?

A: Yes, the ERJ-1TNF19R1U meets all electrical and mechanical substitution criteria. However, its "Not For New Designs" status indicates discontinued development. For new designs, RMCF2512FT19R1 is the recommended choice.

Q: What is the significance of the 0.002" (0.04mm) difference in seated height between the original and substitute parts?

A: The height difference between RC6432F19R1CS (0.026" max) and both substitutes (0.028" max) is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit in standard 2512 package footprints.

Q: Are both substitute parts suitable for automotive applications?

A: Both ERJ-1TNF19R1U and RMCF2512FT19R1 carry AEC-Q200 automotive qualification. The original RC6432F19R1CS does not specify AEC-Q200 rating. If automotive qualification is a design requirement, either substitute part provides this additional assurance.

Q: What packaging formats are available for the substitute parts?

A: RMCF2512FT19R1 is supplied in Cut Tape (CT) format. ERJ-1TNF19R1U is supplied in Tape & Reel (TR) format. The original RC6432F19R1CS packaging format is not specified in the provided data.

Q: Do all three parts share identical RoHS and REACH compliance status?

A: Yes. RC6432F19R1CS, ERJ-1TNF19R1U, and RMCF2512FT19R1 are all ROHS3 compliant and REACH unaffected, with identical MSL rating of 1 (Unlimited).

Q: What is the primary reason to select a substitute part?

A: Substitute parts are selected when the original part becomes unavailable due to supply constraints, discontinuation, or lead time requirements. Both qualified substitutes maintain identical electrical performance and mechanical compatibility with the original RC6432F19R1CS.
