RC6432J914CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432J914CS is a 910 kOhms ±5% 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 1028 units available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. The primary substitute identified is the ERJ-1TNF9103U from Panasonic Electronic Components, which shares the same resistance value, power rating, and package dimensions while offering improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432J914CS is determined by strict alignment with the following core parameters:

Electrical Parameters (Critical):

• Resistance value: 910 kOhms (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or wider range acceptable)

Mechanical Parameters (Critical):

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match or better acceptable)

The ERJ-1TNF9103U from Panasonic meets all critical electrical and mechanical parameters. While this substitute offers ±1% tolerance (superior to the ±5% specification of the main part), it remains functionally compatible for applications where the RC6432J914CS is specified. The substitute maintains identical power rating, temperature coefficient, operating temperature range, package dimensions, and composition type.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (RC6432J914CS): The RC6432J914CS maintains active production status and is recommended for new design implementations. This Samsung component is available in quantity (1028 units in stock) and carries full ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute Part (ERJ-1TNF9103U): The ERJ-1TNF9103U from Panasonic is electrically and mechanically compatible with the RC6432J914CS. This substitute carries AEC-Q200 automotive qualification and offers superior tolerance specification (±1% versus ±5%). However, this part is designated "Not For New Designs," limiting its application to legacy system support, repair operations, or situations where primary part availability is constrained.

Selection between these components should be based on design phase requirements and supply chain constraints. For new designs, the RC6432J914CS is the appropriate choice. For existing systems or temporary supply situations, the ERJ-1TNF9103U provides functional equivalence with enhanced tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-1TNF9103U replace the RC6432J914CS in existing circuit designs?

A: Yes. The ERJ-1TNF9103U maintains identical electrical specifications (910 kOhms, 1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2512 package, thick film composition). The superior ±1% tolerance of the substitute does not create incompatibility with designs specified for ±5% tolerance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF9103U?

A: This designation indicates that Panasonic has discontinued active development and new production allocation for this part number. While the component remains functionally available, it should not be selected for new circuit designs. The RC6432J914CS, with active production status, is the appropriate choice for new implementations.

Q: Are the physical dimensions identical between these two parts?

A: The parts are mechanically compatible within standard PCB assembly tolerances. The RC6432J914CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" maximum seated height. The ERJ-1TNF9103U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" maximum seated height. These dimensional variations fall within standard PCB footprint design margins for the 2512 package format.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RC6432J914CS and ERJ-1TNF9103U are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both maintain MSL 1 (Unlimited) moisture sensitivity rating. The ERJ-1TNF9103U additionally carries AEC-Q200 automotive qualification, which does not conflict with general industrial applications.

Q: What packaging formats are available for these parts?

A: The RC6432J914CS is supplied in standard packaging format. The ERJ-1TNF9103U is available in Tape & Reel (TR) format, which is standard for high-volume automated assembly operations. Packaging format selection depends on assembly process requirements and order quantity.
