RC6432F1150CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1150CS is a 115 Ohms ±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 784 units available in inventory.

Equivalent and substitute parts are identified when applications require alternative sourcing due to supply constraints, inventory availability, or specific certification requirements while maintaining identical electrical and mechanical performance within the defined parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1150CS is determined by strict equivalence across all critical electrical and mechanical parameters. The following criteria establish valid substitutes:

Mandatory Equivalence Parameters:

• Resistance value: 115 Ohms (exact)
• Tolerance: ±1% (exact)
• Power rating: 1W (exact)
• Package designation: 2512 (6432 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature coefficient: ±100ppm/°C (exact)
• Operating temperature range: -55°C to 155°C (exact)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity level: 1 (Unlimited) (exact)

Dimensional Tolerance Allowance: Physical dimensions (length, width, height) may vary within standard manufacturing tolerances for the 2512 package classification. Variations in seated height up to 0.028" (0.70mm) are acceptable within industry standards for this package type.

Certification Considerations: Substitute parts may include additional certifications (such as AEC-Q200 automotive qualification) beyond the base requirements. These represent enhanced specifications and do not disqualify substitution.

Product Status Consideration: Parts designated "Not For New Designs" remain electrically and mechanically equivalent but may have restricted availability or planned discontinuation timelines.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW2512115RFKEG manufactured by Vishay Dale is the preferred substitute for the RC6432F1150CS. Both components maintain active production status, ensuring long-term availability and supply chain stability. The Vishay part includes AEC-Q200 automotive qualification, providing enhanced reliability documentation suitable for demanding applications. Inventory availability of 2567 units supports immediate procurement requirements.

Alternative Selection (Legacy Status): The ERJ-1TNF1150U from Panasonic Electronic Components meets all electrical and mechanical equivalence criteria. However, this part carries a "Not For New Designs" designation, indicating potential future discontinuation. Selection of this part is appropriate only when existing inventory must be maintained or when legacy system compatibility is required. The highest current inventory level (8681 units) may provide short-term sourcing advantages despite the product status restriction.

Compliance Verification: All three parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, confirming suitability for standard industrial and commercial applications without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512115RFKEG be used as a direct replacement for RC6432F1150CS?

A: Yes. Both components are electrically and mechanically equivalent with identical resistance (115 Ohms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The Vishay part includes additional AEC-Q200 automotive certification, which does not restrict its use in non-automotive applications.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF1150U?

A: This designation indicates that Panasonic has classified this part as legacy or end-of-life. While the component remains electrically and mechanically equivalent and is currently in stock, manufacturers typically assign this status when planning production discontinuation. New designs should prioritize parts with "Active" status (RC6432F1150CS or CRCW2512115RFKEG) to ensure long-term supply availability.

Q: Are there dimensional differences between these three parts?

A: Minor dimensional variations exist within standard 2512 package tolerances. The RC6432F1150CS and ERJ-1TNF1150U share identical length (0.248" / 6.30mm and 0.252" / 6.40mm respectively) and width specifications. The CRCW2512115RFKEG width is 0.124" (3.15mm) compared to 0.126" (3.20mm) for the other two parts. All seated heights remain within 0.026" to 0.028" (0.66mm to 0.70mm). These variations are within standard PCB footprint design tolerances for the 2512 package and do not affect interchangeability.

Q: What packaging format differences exist, and do they affect substitution?

A: The RC6432F1150CS is supplied in bulk packaging, while CRCW2512115RFKEG and ERJ-1TNF1150U are supplied in Tape & Reel (TR) format. Packaging format does not affect component performance or electrical equivalence. Selection between bulk and tape & reel depends on assembly process requirements and procurement volume, not on technical substitution criteria.

Q: Are all three parts suitable for the full -55°C to 155°C operating range?

A: Yes. All three components are rated for identical operating temperature ranges of -55°C to 155°C with ±100ppm/°C temperature coefficient. No thermal performance differences exist between the parts.

Q: Do these parts require special handling or storage conditions?

A: No. All three components carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating unlimited shelf life and standard storage conditions without desiccant requirements or bake-out procedures.
