RC6432F6193CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F6193CS is a 619 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 ROHS3 compliant. The part is currently in active production status with 1173 pieces available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained. The primary substitute listed is the ERJ-1TNF6193U from Panasonic Electronic Components, which shares identical resistance, tolerance, power rating, and package dimensions while offering automotive-grade AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6193CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 619 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

Mechanical Specifications:

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

Compliance & Environmental:

• RoHS3 compliance (required for new designs)
• Moisture Sensitivity Level 1 (unlimited shelf life)

The ERJ-1TNF6193U meets all electrical and mechanical equivalence criteria. The primary distinction is its automotive AEC-Q200 qualification and "Not For New Designs" status, which affects application suitability rather than technical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: The RC6432F6193CS is the primary selection. It maintains active product status and is suitable for all new design implementations. Current inventory of 1173 pieces supports production requirements.

For Automotive Applications: The ERJ-1TNF6193U provides AEC-Q200 automotive qualification, making it suitable for automotive-grade applications where this certification is required. However, its "Not For New Designs" status restricts its use to legacy system support or replacement scenarios.

Dimensional Considerations: Minor dimensional variations exist between the two parts. The ERJ-1TNF6193U has a maximum length of 0.252" (6.40mm) compared to 0.248" (6.30mm) for the RC6432F6193CS, and a maximum seated height of 0.028" (0.70mm) versus 0.026" (0.66mm). These differences fall within standard PCB layout tolerances for 2512 package components but should be verified against specific board design constraints.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-1TNF6193U replace the RC6432F6193CS in new product designs?

A: The ERJ-1TNF6193U is electrically and mechanically equivalent but carries a "Not For New Designs" status. For new designs, the RC6432F6193CS is the appropriate selection. The substitute may be used only in legacy system support or replacement applications where the original part is no longer available.

Q: Are there dimensional compatibility issues between these two parts?

A: Both parts use the 2512 (6432 Metric) package. The ERJ-1TNF6193U has slightly larger maximum dimensions (0.252" L vs. 0.248" L and 0.028" H vs. 0.026" H). These differences are within standard 2512 package tolerances. Verify against specific PCB layout requirements, particularly for high-density designs with tight component spacing.

Q: Do both parts meet the same compliance requirements?

A: Both the RC6432F6193CS and ERJ-1TNF6193U are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry Moisture Sensitivity Level 1 (unlimited shelf life). The ERJ-1TNF6193U additionally qualifies to AEC-Q200 automotive standards.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient of ±100ppm/°C indicates the maximum resistance change per degree Celsius across the operating range. Both parts share this specification, ensuring equivalent thermal stability performance in applications spanning -55°C to 155°C.

Q: Can these parts be used interchangeably in existing assemblies?

A: Electrical interchangeability is confirmed across all specified parameters. Mechanical interchangeability depends on PCB layout tolerances. The minor dimensional differences should not affect standard 2512 package footprints, but board-specific design constraints must be evaluated.
