RCS3216F1404CS Equivalent & Substitute Parts

Part Overview

The RCS3216F1404CS is a 1.4 MOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across a temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1404CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.4 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

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

Compliance Parameters:

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

All identified substitute parts meet these criteria without exception. Dimensional variations within the 1206 package specification and differences in secondary features (such as automotive qualification or anti-sulfur coating) do not disqualify substitution when core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS3216F1404CS, CRCW12061M40FKEA, and RC1206FR-071M4L—are active products with ROHS3 compliance and identical core electrical specifications. Selection between these parts is based on availability, packaging format, and application-specific requirements:

RCS3216F1404CS (Samsung Electro-Mechanics): Primary choice when anti-sulfur and moisture-resistant properties are explicitly required. Suitable for general industrial applications with standard environmental protection needs.

CRCW12061M40FKEA (Vishay Dale): Appropriate for automotive applications requiring AEC-Q200 qualification. This part carries automotive-grade reliability certification and is packaged in Tape & Reel format.

RC1206FR-071M4L (YAGEO): Suitable for applications requiring moisture-resistant thick film construction. Packaged in Tape & Reel format with high inventory availability.

All parts maintain identical electrical performance, temperature stability, and compliance certifications. Dimensional variations are within 1206 package tolerances and do not affect PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M40FKEA replace RCS3216F1404CS in non-automotive applications?

A: Yes. The CRCW12061M40FKEA meets all electrical and mechanical requirements of the RCS3216F1404CS. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. All core parameters—resistance, tolerance, power rating, temperature coefficient, and operating range—are identical.

Q: What is the significance of the dimensional differences between RC1206FR-071M4L and the other parts?

A: The RC1206FR-071M4L has a length of 3.10mm compared to 3.20mm for the other parts, and a seated height of 0.65mm versus 0.66mm and 0.60mm respectively. These variations fall within the 1206 (3216 Metric) package specification and do not affect PCB footprint compatibility or assembly processes.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. Selection among them is not constrained by thermal performance requirements.

Q: What packaging formats are available for these substitute parts?

A: RCS3216F1404CS is available in standard packaging. CRCW12061M40FKEA and RC1206FR-071M4L are both available in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control requirements during storage and handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The RCS3216F1404CS, CRCW12061M40FKEA, and RC1206FR-071M4L are direct electrical and mechanical equivalents. No circuit redesign or PCB layout modification is required for substitution.
