RC6432F6190CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F6190CS is a 619 Ohms ±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 level (MSL 1). The part is currently in active production status with 682 pieces available in inventory.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6190CS is determined by strict equivalence across the following parameters:

Mandatory Matching Criteria:

• Resistance value: 619 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package format: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

All three substitute parts listed meet these mandatory criteria. Dimensional variations within the 2512 package specification and differences in product status or certifications do not disqualify substitution eligibility when all electrical and core mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Upgrade Path): AC2512FK-07619RL (YAGEO)

The AC2512FK-07619RL is the recommended primary substitute. It maintains full electrical and mechanical equivalence to the RC6432F6190CS while offering active product status and automotive AEC-Q200 qualification. The Tape & Reel packaging format provides advantages for automated assembly processes. Inventory availability of 2603 pieces supports production continuity.

Secondary Substitute (High Availability): RMCF2512FT619R (Stackpole Electronics Inc)

The RMCF2512FT619R is the secondary substitute option, offering the highest current inventory level at 15337 pieces. This part maintains active product status and includes automotive AEC-Q200 qualification. Stackpole Electronics Inc is an established supplier with consistent product availability.

Legacy Substitute (Restricted Use): ERJ-1TNF6190U (Panasonic Electronic Components)

The ERJ-1TNF6190U is electrically and mechanically equivalent but carries a "Not For New Designs" product status designation. This part is suitable only for replacement, repair, or continuation of existing designs. New product development should not incorporate this part number. Panasonic's automotive AEC-Q200 qualification remains valid for legacy applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC6432F6190CS with AC2512FK-07619RL in my existing design?

A: Yes. Both parts are electrically identical (619 Ohms ±1%, 1W, ±100ppm/°C) and mechanically compatible in the 2512 package. The primary difference is packaging format (bulk versus Tape & Reel) and supplier. No circuit redesign is required.

Q: What is the difference between the three substitute parts?

A: All three substitutes meet the mandatory electrical specifications (619 Ohms ±1%, 1W, -55°C to 155°C operation). The differences are: (1) AC2512FK-07619RL and RMCF2512FT619R are active products; ERJ-1TNF6190U is not for new designs; (2) AC2512FK-07619RL and RMCF2512FT619R include automotive AEC-Q200 qualification; (3) inventory levels vary significantly; (4) packaging formats differ (Tape & Reel versus bulk).

Q: Why is ERJ-1TNF6190U marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent, Panasonic has directed customers toward alternative sources for new product development. The part remains suitable for replacement and repair applications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 2512 package specification. Length ranges from 0.248" to 0.252" (6.30mm to 6.40mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and height from 0.026" to 0.028" (0.65mm to 0.70mm). These variations fall within standard 2512 package tolerances and do not affect circuit performance or PCB layout compatibility.

Q: Which substitute should I choose for automated assembly?

A: AC2512FK-07619RL and RMCF2512FT619R are both supplied in Tape & Reel format, which is standard for automated pick-and-place assembly. RC6432F6190CS is supplied in bulk format. If your assembly process requires Tape & Reel packaging, select either AC2512FK-07619RL or RMCF2512FT619R.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All four parts (RC6432F6190CS, AC2512FK-07619RL, ERJ-1TNF6190U, and RMCF2512FT619R) are rated MSL 1 (Unlimited), meaning they have unlimited shelf life and require no special moisture control during storage or handling.

Q: Are all substitutes RoHS compliant?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
