RC6432F2673CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2673CS is a 267 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant. The part is currently in active production status with 677 pieces available in stock.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the main part. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2673CS is determined by strict alignment of the following parameters:

Electrical Parameters:

• Resistance value: 267 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

The ERJ-1TNF2673U from Panasonic Electronic Components meets all electrical and mechanical substitution criteria. This part maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both components use thick film composition and are housed in the 2512 package with equivalent termination configuration.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2673CS (Samsung Electro-Mechanics): Select this part for new designs and applications requiring active production status. The component is currently in active product status with established supply availability. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for industrial and commercial applications.

ERJ-1TNF2673U (Panasonic Electronic Components): This part is designated "Not For New Designs" and should be used only for replacement, repair, or legacy system maintenance where the original Samsung component is unavailable. The Panasonic part carries AEC-Q200 automotive qualification, which provides additional reliability assurance for demanding environments. Electrical and mechanical equivalence is confirmed across all specified parameters.

Selection between these parts depends on application context: use the Samsung part for new designs; use the Panasonic part for field replacement or when automotive-grade reliability is required and the "Not For New Designs" status is acceptable for the application lifecycle.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2673U replace RC6432F2673CS in existing designs?

A: Yes. Both parts share identical electrical specifications (267 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and package (2512). Mechanical dimensions are compatible within standard PCB footprint tolerances. Both are ROHS3 compliant with MSL 1 rating.

Q: What does "Not For New Designs" mean for the Panasonic part?

A: This designation indicates the ERJ-1TNF2673U is in mature or declining production status. The part remains available for replacement and repair applications but should not be selected for new product development. The Samsung RC6432F2673CS, with active status, is the preferred choice for new designs.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RC6432F2673CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" max height. ERJ-1TNF2673U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" max height. Both fit the 2512 package specification and are compatible with standard 2512 PCB footprints.

Q: Does the Panasonic part's AEC-Q200 rating affect substitution?

A: AEC-Q200 is an automotive qualification that indicates enhanced reliability testing and quality assurance. This certification does not prevent substitution; it provides additional assurance for applications requiring automotive-grade components. The Samsung part does not carry this specific certification but meets all equivalent electrical and compliance requirements.

Q: What packaging formats are available?

A: RC6432F2673CS is supplied in standard packaging. ERJ-1TNF2673U is supplied in Tape & Reel (TR) format. Packaging format does not affect electrical or mechanical compatibility; it only impacts handling, storage, and assembly processes.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient. This range supports industrial and commercial high-temperature applications within the specified limits.
