RC6432F1912CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1912CS is a 19.1 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is classified as Active product status with full ROHS3 compliance.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative qualified sources. The ERJ-1TNF1912U from Panasonic Electronic Components provides electrical and mechanical compatibility, though it carries a Not For New Designs status and includes automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1912CS is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Parameters (Non-negotiable):

• Resistance value: 19.1 kOhms
• Tolerance: ±1%
• Power rating: 1W minimum
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Non-negotiable):

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 acceptable

The ERJ-1TNF1912U meets all electrical and mechanical requirements. Dimensional variations (0.252" L vs. 0.248" L; 0.028" H vs. 0.026" H) remain within acceptable PCB layout tolerances for 2512 package specifications. The substitute carries automotive AEC-Q200 qualification, which exceeds standard industrial requirements and does not restrict substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1912CS (Samsung Electro-Mechanics) is the primary selection for new designs. The component carries Active product status, indicating full manufacturer support, ongoing production, and availability for long-term supply commitments. This part is suitable for all applications requiring 19.1 kOhms ±1% 1W thick film resistors in 2512 package format.

ERJ-1TNF1912U (Panasonic Electronic Components) is qualified as a direct substitute for existing designs or when supply of the primary part is constrained. This component meets all electrical and mechanical specifications identically. However, the Not For New Designs status indicates Panasonic has discontinued active promotion of this part number for new applications. The automotive AEC-Q200 qualification provides additional reliability assurance and does not restrict use in standard industrial or consumer applications.

Selection between these parts should be based on:

• Availability and lead time requirements
• Existing supply chain relationships
• Design phase (new vs. existing)
• Packaging format preference (Samsung offers standard packaging; Panasonic offers Tape & Reel)

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1912U be used as a direct replacement for RC6432F1912CS on existing PCBs?

A: Yes. Both components share identical electrical specifications (19.1 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and the same 2512 package footprint. Dimensional tolerances (length 0.248" vs. 0.252", height 0.026" vs. 0.028") fall within standard PCB layout margins for this package class and do not require design modification.

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

A: This status indicates Panasonic has transitioned the ERJ-1TNF1912U to end-of-life phase and does not recommend it for new product development. However, the part remains available for existing designs and supply commitments. For new designs, Samsung RC6432F1912CS is the recommended primary selection.

Q: Are there differences in reliability or performance between these parts?

A: Both components are thick film resistors with identical electrical performance parameters. The Panasonic part includes automotive AEC-Q200 qualification, which represents additional qualification testing beyond standard industrial requirements. This qualification does not affect performance in non-automotive applications and may provide additional confidence in reliability.

Q: What packaging formats are available?

A: RC6432F1912CS is supplied in standard packaging format. ERJ-1TNF1912U is available in Tape & Reel (TR) format, which is standard for automated assembly processes. Packaging format selection depends on manufacturing process requirements and volume.

Q: Are both parts RoHS compliant?

A: Yes. Both RC6432F1912CS and ERJ-1TNF1912U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficients of ±100ppm/°C. No derating or performance adjustment is required when substituting between these parts in this temperature range.
