Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2550CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 255 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product features (such as automotive AEC-Q200 certification or anti-sulfur coating) do not prevent functional substitution when electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Selection (Recommended for New Designs):

• CRCW1206255RFKEA (Vishay Dale): Active product status with automotive AEC-Q200 qualification. Suitable for applications requiring automotive-grade reliability. 10,395 pieces in stock.
• RC1206FR-07255RL (YAGEO): Active product status with moisture-resistant properties matching the original part. 29,131 pieces in stock.

Secondary Selection (Legacy Applications):

• ERJ-8ENF2550V (Panasonic): Marked as "Not For New Designs" but remains functionally equivalent. Automotive AEC-Q200 qualified. 280,086 pieces in stock. Use only for replacement or maintenance of existing designs.

Original Part:

• RCS3216F2550CS (Samsung): Active status with anti-sulfur and moisture-resistant features. 685 pieces in stock.

Selection should prioritize parts with Active product status for new circuit designs. The ERJ-8ENF2550V should be reserved for legacy system maintenance where design continuity is required.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206255RFKEA directly replace RCS3216F2550CS? A: Yes. Both parts share identical electrical specifications (255 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), use the same 1206 package, and meet ROHS3 compliance. Physical dimensions vary slightly within package tolerance, but this does not affect circuit performance.

Q: What is the difference between the substitute parts? A: All substitute parts meet the core electrical and mechanical requirements. CRCW1206255RFKEA and ERJ-8ENF2550V include automotive AEC-Q200 certification. RC1206FR-07255RL emphasizes moisture resistance. RCS3216F2550CS includes anti-sulfur coating. These are feature additions that do not prevent substitution.

Q: Why is ERJ-8ENF2550V marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development for this part. It remains functionally equivalent and suitable for replacement applications, but should not be selected for new circuit designs where active product alternatives exist.

Q: Are there package compatibility concerns? A: All parts use the 1206 (3216 Metric) package with identical footprints. Seated heights vary between 0.024" and 0.028" (0.60mm to 0.70mm), which falls within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Do compliance certifications affect substitution? A: No. All parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Automotive AEC-Q200 certification on some parts is an additional qualification that does not prevent use in non-automotive applications.

Q: What is the inventory status for each part? A: RCS3216F2550CS: 685 pieces. CRCW1206255RFKEA: 10,395 pieces. ERJ-8ENF2550V: 280,086 pieces. RC1206FR-07255RL: 29,131 pieces. Availability should be confirmed with supplier for production requirements.
