Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F2610CS is determined by strict equivalence across the following parameters: resistance value (261 Ohms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts meet these core electrical and mechanical requirements. Dimensional variations within supplier tolerances and differences in product status or feature sets (such as automotive qualification) do not disqualify substitution eligibility when core parameters align.

Engineering Selection Recommendations

All three substitute parts—RC1206FR-07261RL (YAGEO), CRCW1206261RFKEA (Vishay Dale), and ERJ-8ENF2610V (Panasonic)—satisfy the core electrical and mechanical requirements for direct substitution with the RC3216F2610CS.

RC1206FR-07261RL and CRCW1206261RFKEA are both in active production status and carry full ROHS3 compliance with MSL 1 rating. CRCW1206261RFKEA includes automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

ERJ-8ENF2610V is marked as "Not For New Designs" and should be used only in existing production or legacy applications where supply continuity is required. This part also carries AEC-Q200 qualification but is not recommended for new design implementations.

Selection between active-status alternatives should be based on availability, packaging preferences, and any application-specific requirements such as automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07261RL (YAGEO) be used as a direct replacement for RC3216F2610CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (261 Ohms, ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), feature ±100ppm/°C temperature coefficient, and are packaged in 1206 (3216 Metric) format. Both are ROHS3 compliant with MSL 1 rating. Dimensional variations (length 3.10mm vs. 3.20mm, height 0.65mm vs. 0.66mm) fall within standard PCB layout tolerances for 1206 components.

Q: What is the difference between CRCW1206261RFKEA and the other substitutes?

A: CRCW1206261RFKEA is qualified to automotive AEC-Q200 standard, whereas RC3216F2610CS and RC1206FR-07261RL do not carry this designation. All other electrical and mechanical parameters are equivalent. The AEC-Q200 qualification indicates enhanced reliability testing and is applicable for automotive applications.

Q: Why is ERJ-8ENF2610V marked "Not For New Designs"?

A: ERJ-8ENF2610V carries a "Not For New Designs" status from Panasonic Electronic Components, indicating that the manufacturer is phasing out this part number. While it meets all electrical and mechanical requirements and remains in stock, it should be used only for sustaining production or legacy applications. For new designs, RC1206FR-07261RL or CRCW1206261RFKEA are preferred alternatives.

Q: Are there any dimensional concerns when substituting these parts on existing PCBs?

A: Dimensional variations are minimal and within standard PCB design tolerances for 1206 components. The length ranges from 3.10mm to 3.20mm, width is consistent at 1.60mm, and height ranges from 0.60mm to 0.70mm. These variations do not affect PCB footprint compatibility or soldering performance on standard 1206 land patterns.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the main part RC3216F2610CS and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-07261RL (YAGEO) has the highest inventory with 112,050 pieces in stock, compared to 13,474 pieces for CRCW1206261RFKEA and 58,620 pieces for ERJ-8ENF2610V.
