RC6432F134CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F134CS is a 130 kOhms ±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 is ROHS3 compliant. The part is currently in active production status with 1174 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative qualified sources. The RC6432F134CS has been identified with one direct electrical and mechanical equivalent: the ERJ-1TNF1303U from Panasonic Electronic Components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F134CS is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 130 kOhms (exact match required)
• Tolerance: ±1% (precision class must match)
• Power rating: 1W (minimum; higher ratings acceptable)
• Package: 2512 (6432 Metric) (physical compatibility)
• Composition: Thick Film (technology type)
• Temperature coefficient: ±100ppm/°C (stability specification)
• Operating temperature range: -55°C ~ 155°C (environmental limits)
• Moisture Sensitivity Level: 1 (Unlimited) (handling compatibility)
• RoHS compliance: ROHS3 (regulatory requirement)

The ERJ-1TNF1303U from Panasonic meets all these criteria. While it carries an automotive AEC-Q200 qualification and is marked "Not For New Designs," it maintains electrical and mechanical equivalence to the RC6432F134CS across all specified parameters.

Engineering Selection Recommendations

Primary Selection: RC6432F134CS (Samsung Electro-Mechanics)

The RC6432F134CS is the recommended choice for new designs. It maintains active production status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. With 1174 units in current inventory, immediate procurement is feasible.

Substitute Selection: ERJ-1TNF1303U (Panasonic Electronic Components)

The ERJ-1TNF1303U is electrically and mechanically equivalent to the RC6432F134CS and is suitable for direct substitution in existing designs or when primary part availability is constrained. This part carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. However, its "Not For New Designs" status indicates Panasonic is transitioning this product line. The ERJ-1TNF1303U is available in Tape & Reel packaging with 4973 units in inventory.

Selection Criteria:

• Use RC6432F134CS for new designs requiring long-term support
• Use ERJ-1TNF1303U for legacy design updates or supply contingency
• Both parts are suitable for applications requiring -55°C to 155°C operation
• Both parts meet ROHS3 and MSL 1 requirements
• Dimensional variations (0.04mm length, 0.04mm height) are within standard PCB tolerance

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1303U be used as a direct replacement for RC6432F134CS in existing assemblies?

A: Yes. The ERJ-1TNF1303U meets all electrical specifications (130 kOhms ±1%, 1W, ±100ppm/°C) and operates across the same temperature range (-55°C to 155°C). Physical dimensions are compatible within standard PCB manufacturing tolerances. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF1303U?

A: This designation indicates Panasonic is discontinuing or transitioning this product line. The part remains available and functional but should not be selected for new product development. It is suitable for sustaining production of existing designs or as a temporary supply alternative.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC6432F134CS measures 6.30mm L × 3.20mm W × 0.66mm H (max), while the ERJ-1TNF1303U measures 6.40mm L × 3.20mm W × 0.70mm H (max). These differences fall within standard PCB design tolerances and do not affect interchangeability.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the RC6432F134CS and ERJ-1TNF1303U operate across -55°C to 155°C with identical temperature coefficients of ±100ppm/°C.

Q: What packaging formats are available?

A: The RC6432F134CS is supplied in standard packaging (format not specified in data). The ERJ-1TNF1303U is available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling beyond standard component storage practices.
