RC6432F304CS Equivalent & Substitute Parts

Part Overview

The RC6432F304CS is a 300 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 maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 866 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for functionally compatible alternatives from different manufacturers that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RC6432F304CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 300 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 ~ 155°C (exact match required)

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (required)

All substitute parts listed meet these criteria without exception. Substitute parts may include additional features such as automotive AEC-Q200 qualification, which represents enhanced reliability specifications beyond the base requirements of the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC6432F304CS - Samsung Electro-Mechanics): The RC6432F304CS remains the primary choice for new designs and ongoing production. This part maintains active product status with established supply availability (866 pieces in stock) and meets all baseline compliance requirements including ROHS3 and unlimited moisture sensitivity rating.

Upgrade Alternative (AC2512FK-07300KL - YAGEO): The AC2512FK-07300KL serves as a direct upgrade substitute with identical electrical and mechanical specifications. This part adds automotive AEC-Q200 qualification and maintains active product status. Supply availability is higher (1864 pieces in stock). Selection of this part is appropriate when automotive-grade reliability is required or when supply chain optimization favors YAGEO inventory.

Legacy Alternative (ERJ-1TNF3003U - Panasonic Electronic Components): The ERJ-1TNF3003U meets all electrical and mechanical equivalence criteria and includes automotive AEC-Q200 qualification. However, this part carries "Not For New Designs" product status. This part is suitable only for replacement, repair, or maintenance of existing assemblies where design continuity is required. New designs should not incorporate this part number.

Active Alternative (RMCF2512FT300K - Stackpole Electronics Inc): The RMCF2512FT300K provides full electrical and mechanical equivalence with active product status and automotive AEC-Q200 qualification. Supply availability is substantial (4882 pieces in stock). This part is suitable for new designs and represents a viable alternative when Stackpole supply chain relationships are preferred.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC6432F304CS with any of the listed alternatives without circuit redesign?

A: Yes. All listed substitute parts meet identical electrical parameters (300 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (2512 package, 2 terminations). Direct substitution is electrically and mechanically compatible without circuit modification.

Q: What is the difference between the main part and the substitute parts?

A: The RC6432F304CS, AC2512FK-07300KL, and RMCF2512FT300K are functionally identical with active product status. The ERJ-1TNF3003U is functionally identical but carries "Not For New Designs" status. The AC2512FK-07300KL, ERJ-1TNF3003U, and RMCF2512FT300K include automotive AEC-Q200 qualification, which the RC6432F304CS does not specify. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Q: Why is the ERJ-1TNF3003U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy support only. New product designs should not incorporate this part number. However, it remains suitable for replacement and maintenance of existing assemblies using this component.

Q: Are there packaging differences between these parts?

A: All parts use the 2512 (6432 Metric) package format. Dimensional variations are minor and within standard manufacturing tolerances. The RC6432F304CS and RMCF2512FT300K share identical length (0.248" / 6.30mm) and width (0.126" / 3.20mm). The AC2512FK-07300KL has slightly larger dimensions (0.250" L x 0.122" W / 6.35mm x 3.10mm). The ERJ-1TNF3003U has slightly larger dimensions (0.252" L x 0.126" W / 6.40mm x 3.20mm). These dimensional differences do not affect PCB footprint compatibility for standard 2512 land patterns.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select either AC2512FK-07300KL (YAGEO), ERJ-1TNF3003U (Panasonic), or RMCF2512FT300K (Stackpole). All three include automotive AEC-Q200 qualification. Avoid ERJ-1TNF3003U for new automotive designs due to its "Not For New Designs" status. AC2512FK-07300KL and RMCF2512FT300K are both suitable for new automotive designs.

Q: What is the inventory status for each part?

A: RC6432F304CS: 866 pieces. AC2512FK-07300KL: 1864 pieces. ERJ-1TNF3003U: 14903 pieces. RMCF2512FT300K: 4882 pieces. Inventory levels should be confirmed with the supplier for current availability.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and are REACH unaffected. All parts carry unlimited moisture sensitivity rating (MSL 1).
