Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F63R4CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 63.4 Ohms
• Tolerance: ±1%
• Power rating: 1W (minimum)
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Manufacturer identity
• Packaging format (Tape & Reel vs. bulk)
• Physical dimensions within 2512 package tolerance
• Additional certifications (e.g., AEC-Q200 automotive qualification)
• Product status (Active or Not For New Designs)

The identified substitutes AC2512FK-0763R4L (YAGEO) and ERJ-1TNF63R4U (Panasonic Electronic Components) meet all mandatory parameters and are therefore electrically and mechanically interchangeable with the RC6432F63R4CS.

Parameter Comparison

Engineering Selection Recommendations

AC2512FK-0763R4L (YAGEO) - Upgrade Substitute: This part is recommended as the primary substitute. It maintains all electrical and mechanical specifications of the RC6432F63R4CS while offering AEC-Q200 automotive qualification, ROHS3 compliance, and active production status. The Tape & Reel packaging format supports automated assembly processes. Higher inventory availability (2762 pieces) provides supply chain security.

ERJ-1TNF63R4U (Panasonic Electronic Components) - Alternative Substitute: This part meets all core electrical and mechanical requirements and carries AEC-Q200 automotive qualification. However, it is designated "Not For New Designs," indicating end-of-life status. The significantly higher inventory level (18264 pieces) may support legacy system maintenance or high-volume legacy production requirements. Use is appropriate only when new design adoption is not a consideration.

Selection between these substitutes should be based on product lifecycle requirements, supply chain strategy, and packaging format compatibility with manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0763R4L be used as a direct replacement for RC6432F63R4CS in new designs?

A: Yes. Both parts share identical electrical specifications (63.4 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), identical package geometry (2512/6432 Metric), and equivalent compliance certifications (ROHS3, MSL 1). The AC2512FK-0763R4L additionally carries AEC-Q200 automotive qualification. Physical dimensions are within 2512 package tolerance. No circuit redesign is required.

Q: What is the difference between the packaging formats listed?

A: RC6432F63R4CS is supplied in bulk packaging. AC2512FK-0763R4L and ERJ-1TNF63R4U are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly. Both formats contain identical components; packaging format selection depends on manufacturing process requirements.

Q: Why is ERJ-1TNF63R4U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and Panasonic does not recommend its use in new product development. It remains available for legacy system support and maintenance. For new designs, AC2512FK-0763R4L or RC6432F63R4CS are appropriate selections.

Q: Are the physical dimensions identical across all three parts?

A: Physical dimensions are within 2512 package specification tolerance. RC6432F63R4CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" max height. AC2512FK-0763R4L measures 0.250" L × 0.122" W (6.35mm × 3.10mm) with 0.026" max height. ERJ-1TNF63R4U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" max height. All dimensions fall within standard 2512 package tolerance and are PCB footprint compatible.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, carry MSL 1 (Unlimited) moisture sensitivity rating, and share ECCN EAR99 and HTSUS 8533.21.0030 classifications. AC2512FK-0763R4L and ERJ-1TNF63R4U additionally carry AEC-Q200 automotive qualification, which is not specified for RC6432F63R4CS.

Q: Can these parts be used interchangeably in automotive applications?

A: AC2512FK-0763R4L and ERJ-1TNF63R4U carry explicit AEC-Q200 automotive qualification. RC6432F63R4CS does not specify automotive qualification. For applications requiring AEC-Q200 compliance, AC2512FK-0763R4L or ERJ-1TNF63R4U are appropriate selections. For non-automotive applications, all three parts are functionally equivalent.
