RC6432F1911CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1911CS is a 1.91 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 831 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified alternatives is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1911CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 1.91 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 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

The ERJ-1TNF1911U from Panasonic Electronic Components meets all mandatory electrical and mechanical parameters. While this substitute carries an AEC-Q200 automotive qualification (an additional feature not present in the primary part), this does not disqualify it as a substitute. The part maintains identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1911CS (Primary Part): This component is in active production status and is the preferred selection for new designs. With 831 pieces in current inventory, it provides immediate availability and long-term supply continuity.

ERJ-1TNF1911U (Substitute Part): This Panasonic equivalent meets all electrical and mechanical specifications. However, it carries a "Not For New Designs" status, indicating that Panasonic has discontinued active development for this part number. The ERJ-1TNF1911U is suitable for replacement, repair, or legacy system applications where the primary part is unavailable. The AEC-Q200 automotive qualification present in this substitute provides additional reliability assurance for applications requiring automotive-grade components.

Selection between these parts should be based on availability, supply chain requirements, and design phase. For new designs, the RC6432F1911CS is the recommended choice. For existing systems or when primary supply is constrained, the ERJ-1TNF1911U provides full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1911U be used as a direct replacement for RC6432F1911CS in existing designs?

A: Yes. Both parts share identical electrical specifications (1.91 kOhms ±1%, 1W), identical package dimensions (2512/6432 Metric), and identical operating characteristics (±100ppm/°C, -55°C to 155°C). They are mechanically and electrically interchangeable.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF1911U?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part number. While the part remains functionally equivalent and available in inventory (7539 pieces), it is not recommended for incorporation into new product designs. It is suitable for replacement, repair, or legacy applications.

Q: Are there dimensional differences between the two parts?

A: Both parts use the 2512 (6432 Metric) package. Minor dimensional variations exist: RC6432F1911CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height, while ERJ-1TNF1911U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.028" max height. These variations fall within standard PCB layout tolerances and do not affect interchangeability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC6432F1911CS and ERJ-1TNF1911U are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. The ERJ-1TNF1911U includes additional AEC-Q200 automotive qualification.

Q: What packaging formats are available?

A: RC6432F1911CS is supplied in standard packaging. ERJ-1TNF1911U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly operations.

Q: Which part should be selected for a new product design?

A: The RC6432F1911CS is the recommended choice for new designs due to its active production status and long-term availability assurance.
