RC6432F23R7CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F23R7CS is a 23.7 Ohm ±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 maintains ROHS3 compliance with MSL 1 rating. The part is currently in active production status with 818 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, supply chain alternatives, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F23R7CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 23.7 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match or better)

Mechanical Compatibility Requirements:

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

Environmental & Compliance Requirements:

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

All identified substitute parts meet these criteria. Dimensional variations within manufacturing tolerances do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

AC2512FK-0723R7L (YAGEO) and CRCW251223R7FKEG (Vishay Dale) are recommended as primary substitutes. Both parts maintain active production status and carry AEC-Q200 automotive qualification in addition to the base electrical and environmental specifications. These parts are suitable for new designs and long-term supply chain planning.

Secondary Selection (Legacy Status):

ERJ-1TNF23R7U (Panasonic) meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies where the original specification must be maintained. New design implementations should not incorporate this part number.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original RC6432F23R7CS specification. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, eliminating moisture-related handling restrictions.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0723R7L replace RC6432F23R7CS in existing designs?

A: Yes. AC2512FK-0723R7L is electrically and mechanically equivalent. Both parts share identical resistance (23.7 Ohms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Dimensional variations (6.35mm x 3.10mm vs. 6.30mm x 3.20mm) fall within standard PCB pad tolerances for 2512 packages.

Q: What is the difference between the substitute parts?

A: All three substitute parts (AC2512FK-0723R7L, CRCW251223R7FKEG, ERJ-1TNF23R7U) are electrically identical to the main part. The primary differences are manufacturer, packaging format (all use Tape & Reel), and product status. AC2512FK-0723R7L and CRCW251223R7FKEG are active products; ERJ-1TNF23R7U is not recommended for new designs.

Q: Are these parts suitable for automotive applications?

A: AC2512FK-0723R7L and CRCW251223R7FKEG carry AEC-Q200 automotive qualification. The original RC6432F23R7CS does not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, use AC2512FK-0723R7L or CRCW251223R7FKEG.

Q: What is the significance of "Not For New Designs" status for ERJ-1TNF23R7U?

A: This designation indicates the manufacturer is not actively promoting the part for new circuit designs. The part remains available for replacement and repair applications. New product development should prioritize AC2512FK-0723R7L or CRCW251223R7FKEG to ensure long-term supply availability and manufacturer support.

Q: Do packaging differences affect substitution?

A: The RC6432F23R7CS is supplied in bulk packaging, while all substitutes use Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical performance. Tape & Reel packaging is standard for automated assembly environments.

Q: Are there moisture handling differences between these parts?

A: No. All parts, including the main part and substitutes, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. Standard storage conditions apply uniformly across all options.
