Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F14R3CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 14.3 Ohms, tolerance of ±1%, power rating of 1W, and temperature coefficient of ±100ppm/°C must match exactly.

Mechanical Parameters: Package designation of 2512 (6432 Metric) with two terminations ensures physical and functional compatibility in PCB layouts.

Environmental & Compliance: Operating temperature range of -55°C to 155°C, RoHS3 compliance, and MSL rating of 1 (Unlimited) must be maintained.

Composition: Thick film construction is required for thermal and electrical performance consistency.

The identified substitutes ERJ-1TNF14R3U and RMCF2512FT14R3 satisfy all these criteria and are therefore electrically and mechanically interchangeable with the RC6432F14R3CS.

Parameter Comparison

Engineering Selection Recommendations

RC6432F14R3CS (Samsung Electro-Mechanics): Primary selection for new designs. Active product status ensures long-term availability and supply chain stability. Moisture-resistant thick film construction with unlimited MSL rating provides robust performance in standard industrial and consumer applications.

RMCF2512FT14R3 (Stackpole Electronics Inc): Qualified substitute with active product status. Includes AEC-Q200 automotive qualification, making this part suitable for automotive and high-reliability applications. Dimensions and electrical specifications are identical to the primary part.

ERJ-1TNF14R3U (Panasonic Electronic Components): Qualified substitute with AEC-Q200 automotive qualification. Product status is "Not For New Designs," indicating this part is in mature phase. Suitable for replacement and maintenance applications where existing inventory exists. Slight dimensional variation (0.252" L vs. 0.248" L) is within standard PCB layout tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF14R3U replace RC6432F14R3CS in new product designs?

A: ERJ-1TNF14R3U has a product status of "Not For New Designs." While electrically and mechanically equivalent, RMCF2512FT14R3 or RC6432F14R3CS are preferred for new designs to ensure long-term component availability.

Q: What is the significance of AEC-Q200 qualification on RMCF2512FT14R3 and ERJ-1TNF14R3U?

A: AEC-Q200 is an automotive industry qualification standard. These parts meet enhanced reliability and quality requirements for automotive applications. The RC6432F14R3CS does not carry this designation but remains suitable for non-automotive applications.

Q: Are there dimensional differences between these three parts?

A: All three parts use the 2512 (6432 Metric) package. RC6432F14R3CS and RMCF2512FT14R3 have identical length (0.248" / 6.30mm). ERJ-1TNF14R3U has a length of 0.252" (6.40mm), a 0.02mm difference within standard PCB footprint tolerances. Height variations (0.66mm to 0.70mm) are also within acceptable assembly clearance limits.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life without special moisture control measures. All three substitute parts carry this rating, eliminating moisture-related storage concerns.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts share identical electrical specifications (14.3 Ohms ±1%, 1W, ±100ppm/°C), the same 2512 package footprint, and compatible operating temperature ranges. PCB layouts designed for RC6432F14R3CS accommodate RMCF2512FT14R3 and ERJ-1TNF14R3U without modification.
