Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2671CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.67 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)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 compliance (mandatory)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match)
• REACH Unaffected status (maintained)

Substitute parts are classified as follows:

Upgrade Substitute: AC2512FK-072K67L (YAGEO) — Meets all electrical and mechanical equivalence criteria with additional automotive AEC-Q200 qualification.

Similar Substitute: ERJ-1TNF2671U (Panasonic Electronic Components) — Meets all electrical and mechanical equivalence criteria with automotive AEC-Q200 qualification; however, product status is "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production): The RC6432F2671CS remains the preferred choice for new designs when Samsung Electro-Mechanics sourcing is established and inventory is available.

Upgrade Alternative (Recommended for Automotive Applications): The AC2512FK-072K67L (YAGEO) is the recommended substitute when automotive-grade qualification is required. This part maintains full electrical and mechanical equivalence while providing AEC-Q200 certification. Higher inventory availability (7445 units) supports supply chain continuity.

Legacy Alternative (Restricted Use): The ERJ-1TNF2671U (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria and carries AEC-Q200 qualification. However, its "Not For New Designs" status restricts application to legacy product support and field replacements only. This part should not be selected for new design implementations.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory and handling compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-072K67L be used as a direct replacement for RC6432F2671CS?

A: Yes. The AC2512FK-072K67L meets all electrical specifications (2.67 kOhms, ±1%, 1W), mechanical requirements (2512 package, thick film), and environmental ratings (operating temperature -55°C ~ 155°C, MSL 1). Both parts are ROHS3 compliant. The YAGEO part includes additional AEC-Q200 automotive qualification.

Q: Why is ERJ-1TNF2671U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued this part for new applications. While the part remains electrically and mechanically equivalent, it should be used only for field replacements or legacy product support. New designs should select RC6432F2671CS or AC2512FK-072K67L.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within tolerance. RC6432F2671CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" max height. AC2512FK-072K67L measures 0.250" L × 0.122" W (6.35mm × 3.10mm) with 0.026" max height. ERJ-1TNF2671U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" max height. All dimensions remain within 2512 package specification and are PCB footprint compatible.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry standard for passive components. Parts carrying this qualification have undergone enhanced reliability testing for automotive applications. AC2512FK-072K67L and ERJ-1TNF2671U both carry AEC-Q200 certification, making them suitable for automotive-grade designs.

Q: Does moisture resistance differ between these parts?

A: RC6432F2671CS and AC2512FK-072K67L are both specified as moisture resistant. ERJ-1TNF2671U does not explicitly specify moisture resistance in the provided data. All three parts maintain MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity during handling and storage.

Q: Which part should be selected for maximum supply availability?

A: AC2512FK-072K67L (YAGEO) offers the highest inventory availability at 7445 units, compared to 964 units for RC6432F2671CS and 4644 units for ERJ-1TNF2671U. For applications requiring supply chain security, AC2512FK-072K67L is the optimal choice.
