RCS3216F1214CS Equivalent & Substitute Parts

Part Overview

The RCS3216F1214CS is a 1.21 MOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is Active in product status and ROHS3 compliant with MSL 1 rating. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F1214CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 1.21 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel vs. bulk) do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

CRCW12061M21FKEA (Vishay Dale) is qualified as a direct substitute for RCS3216F1214CS. This part carries AEC-Q200 automotive qualification in addition to standard compliance requirements. The CRCW series maintains identical electrical specifications and 1206 package compatibility. Height dimension is 0.024" (0.60mm), which is within acceptable tolerance variance for 1206 package specifications.

RC1206FR-071M21L (YAGEO) is qualified as a direct substitute for RCS3216F1214CS. This part maintains identical electrical specifications and 1206 package compatibility. Physical dimensions are within standard tolerance ranges for the 1206 package form factor. The RC_L series provides moisture-resistant thick film construction consistent with the original part.

Both substitute parts are Active in product status, ROHS3 compliant, and carry MSL 1 rating. Selection between substitutes should be based on availability, packaging format requirements (Tape & Reel vs. bulk), and application-specific needs such as automotive qualification (CRCW series).

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M21FKEA replace RCS3216F1214CS in all applications?

A: Yes. CRCW12061M21FKEA meets all electrical and mechanical parameters required for substitution. The part is electrically identical with 1.21 MOhms ±1% resistance, 0.25W power rating, and identical temperature coefficient. The 1206 package is mechanically compatible. AEC-Q200 qualification provides additional automotive-grade assurance.

Q: What is the difference between the three parts in terms of physical dimensions?

A: All three parts use the 1206 (3216 Metric) package. Length varies slightly: RCS3216F1214CS and CRCW12061M21FKEA are 0.126" (3.20mm), while RC1206FR-071M21L is 0.122" (3.10mm). Height ranges from 0.024" to 0.026" across all three parts. These variations fall within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Are there packaging format differences between these substitutes?

A: RCS3216F1214CS is supplied in standard packaging format. CRCW12061M21FKEA and RC1206FR-071M21L are both supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and is compatible with standard pick-and-place equipment.

Q: Do all three parts have the same compliance certifications?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. CRCW12061M21FKEA additionally carries AEC-Q200 automotive qualification. This additional qualification does not restrict use in non-automotive applications.

Q: What is the temperature coefficient specification and does it differ across parts?

A: All three parts specify ±100ppm/°C temperature coefficient with operating range -55°C to 155°C. This specification is identical across RCS3216F1214CS, CRCW12061M21FKEA, and RC1206FR-071M21L.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts are mechanically and electrically compatible for PCB assembly. The 1206 package footprint is standardized, and all parts have identical lead spacing and termination count (2 terminations). Assembly equipment settings and reflow profiles remain unchanged.
