Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F1744CS are qualified based on strict equivalence of the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.74 MOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 1206 (3216 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

All identified substitutes meet these criteria. Packaging format (Tape & Reel vs. other formats) does not affect electrical or mechanical compatibility and represents a supply chain variable only.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

RC3216F1744CS (Samsung Electro-Mechanics): Primary specification. Moisture-resistant thick film construction. Current inventory: 862 units.

RC1206FR-071M74L (YAGEO): Direct equivalent with identical electrical specifications and moisture-resistant features. Supplied in Tape & Reel format. Current inventory: 10,712 units. Suitable for high-volume production environments requiring automated assembly.

CRCW12061M74FKEA (Vishay Dale): Direct equivalent with identical electrical specifications. Includes AEC-Q200 automotive qualification rating. Supplied in Tape & Reel format. Current inventory: 18,588 units. Recommended for applications requiring automotive-grade component certification.

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M74L replace RC3216F1744CS in existing designs?

A: Yes. Both parts share identical electrical specifications (1.74 MOhms, ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package format (1206 / 3216 Metric). Both are thick film, moisture-resistant, ROHS3 compliant, and have MSL 1 rating.

Q: What is the difference between RC1206FR-071M74L and CRCW12061M74FKEA?

A: Electrical and mechanical specifications are identical. The primary difference is that CRCW12061M74FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Both are supplied in Tape & Reel packaging.

Q: Does packaging format (Tape & Reel vs. other formats) affect compatibility?

A: No. Packaging format is a supply chain and assembly process variable. It does not affect electrical performance, mechanical fit, or thermal characteristics. All three parts are mechanically compatible in the same PCB footprint.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist within tolerance. RC3216F1744CS and CRCW12061M74FKEA are specified at 0.126" L x 0.063" W (3.20mm x 1.60mm). RC1206FR-071M74L is specified at 0.122" L x 0.063" W (3.10mm x 1.60mm). Height variations range from 0.024" to 0.026" (0.60mm to 0.66mm). These variations are within standard 1206 package tolerances and do not affect PCB assembly or electrical function.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and supply chain strategy. For general applications, any of the three parts is suitable. For automotive applications, CRCW12061M74FKEA is specified due to AEC-Q200 qualification. For high-volume production, parts with larger inventory (YAGEO or Vishay Dale) may offer supply chain advantages.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.
