RC6432F1580CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1580CS is a 158 Ohms ±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 maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 661 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when design requirements mandate specific certifications such as AEC-Q200 automotive qualification, or when alternative suppliers offer equivalent electrical and mechanical performance within the same package specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1580CS is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance value: 158 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. bulk)
• Product status (Active vs. Not For New Designs)
• Physical dimensions within tolerance (length ±0.004", height ±0.002")
• Additional certifications (AEC-Q200 automotive qualification)

The two identified substitute parts—ERJ-1TNF1580U (Panasonic) and RMCF2512FT158R (Stackpole)—satisfy all mandatory parameters and are therefore electrically and mechanically interchangeable with the RC6432F1580CS.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1580CS (Samsung Electro-Mechanics): Select this part for new designs requiring active production status and standard industrial-grade thick film resistor performance. The part carries ROHS3 compliance and unlimited moisture sensitivity rating suitable for general commercial applications.

ERJ-1TNF1580U (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification and is suitable for automotive and high-reliability applications. However, the product status is listed as "Not For New Designs," indicating this part is in mature or end-of-life phase. Use only when automotive certification is mandatory and supply chain constraints prevent use of active-status alternatives.

RMCF2512FT158R (Stackpole Electronics Inc): This substitute is recommended as the primary alternative to RC6432F1580CS. It maintains active production status, carries AEC-Q200 automotive qualification for enhanced reliability, and provides equivalent electrical and mechanical performance. Physical dimensions are within acceptable tolerance for PCB layout compatibility.

Selection between RC6432F1580CS and RMCF2512FT158R depends on supplier availability and design requirements. Both are active-status parts with identical core electrical specifications. The Stackpole part offers automotive-grade certification as an additional feature without compromising standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1580U replace RC6432F1580CS in new product designs?

A: ERJ-1TNF1580U is electrically and mechanically equivalent to RC6432F1580CS. However, Panasonic lists this part as "Not For New Designs," indicating it is in mature production phase. For new designs, RMCF2512FT158R is the preferred substitute as it maintains active production status while providing identical electrical performance and additional AEC-Q200 automotive certification.

Q: What is the significance of the physical dimension differences between these parts?

A: RC6432F1580CS and RMCF2512FT158R share identical length (0.248") and width (0.126"). ERJ-1TNF1580U has a slightly longer length (0.252") and greater seated height (0.028" vs. 0.026"). These variations remain within standard 2512 package tolerances and do not affect PCB footprint compatibility or electrical performance. Verify PCB layout clearances if height-constrained applications are present.

Q: Are all three parts suitable for automotive applications?

A: RC6432F1580CS is a standard industrial-grade resistor without automotive certification. ERJ-1TNF1580U and RMCF2512FT158R both carry AEC-Q200 automotive qualification. For automotive applications, select either ERJ-1TNF1580U or RMCF2512FT158R. RMCF2512FT158R is preferred due to active production status.

Q: What does "Not For New Designs" mean for ERJ-1TNF1580U?

A: This designation indicates the part is in mature or declining production phase. Panasonic continues to supply existing inventory but does not recommend this part for new product development. Existing designs using ERJ-1TNF1580U can continue production, but new designs should transition to active-status alternatives such as RMCF2512FT158R.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and are suitable for standard warehouse and manufacturing environments.

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

A: Yes, all three parts are mechanically compatible with 2512 package footprints. Physical dimension variations are within standard tolerances. Verify component placement clearances if height is constrained. Electrical performance is identical across all three parts for standard circuit applications.
