Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2373CS is determined by strict alignment of the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 237 kOhms (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 wider range acceptable)

Mechanical Compatibility Requirements:

• Package type: 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 lower MSL acceptable)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• REACH Status: REACH Unaffected (minimum requirement)

The identified substitute parts meet all electrical, mechanical, and compliance criteria. Dimensional variations within manufacturing tolerances do not preclude substitution.

Engineering Selection Recommendations

Primary Selection (Active Production): The CRCW2512237KFKEG from Vishay Dale is the preferred substitute. This part maintains active production status, meets all electrical and mechanical specifications, and carries AEC-Q200 automotive qualification. It is available in Tape & Reel packaging with 6174 pieces in inventory.

Secondary Selection (Legacy Status): The ERJ-1TNF2373U from Panasonic Electronic Components meets all electrical and mechanical requirements but carries a "Not For New Designs" product status. This part is suitable only for replacement or maintenance applications in existing designs. It is available in Tape & Reel packaging with 3701 pieces in inventory.

Compliance Verification: All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution and use.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512237KFKEG replace RC6432F2373CS in new designs? A: Yes. The CRCW2512237KFKEG meets all electrical specifications (237 kOhms ±1%, 1W, ±100ppm/°C), operates across the same temperature range (-55°C ~ 155°C), uses identical 2512 package geometry, and maintains ROHS3 compliance. The part is in active production.

Q: What is the difference between the Samsung and Vishay parts? A: Both parts are electrically and mechanically equivalent. The Vishay CRCW2512237KFKEG includes AEC-Q200 automotive qualification and is supplied in Tape & Reel format. The Samsung RC6432F2373CS includes moisture-resistant features and is supplied in bulk packaging. Dimensional tolerances vary slightly within manufacturing standards.

Q: Why is the Panasonic ERJ-1TNF2373U marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development for new applications. The part remains electrically and mechanically equivalent and is suitable for replacement in existing designs or legacy production runs.

Q: Are there packaging format considerations for substitution? A: Yes. The RC6432F2373CS is supplied in bulk packaging, while CRCW2512237KFKEG and ERJ-1TNF2373U are supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes. Bulk packaging may require manual handling or reeling for automated placement equipment.

Q: Do dimensional variations affect substitution eligibility? A: No. All three parts use the 2512 (6432 Metric) package. Dimensional variations (length 6.30mm to 6.40mm, width 3.15mm to 3.20mm, height 0.66mm to 0.70mm) fall within manufacturing tolerances and do not affect PCB footprint compatibility or electrical performance.

Q: What is Moisture Sensitivity Level 1? A: MSL 1 indicates unlimited shelf life without moisture control requirements. All three parts carry this rating, meaning they do not require special desiccant packaging or baking procedures prior to assembly.
