RCS3216F685CS Equivalent & Substitute Parts

Part Overview

The RCS3216F685CS is a 6.8 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 ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently active in production with 1054 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F685CS are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Resistance value: 6.8 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 or Exceed):

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

Both identified substitute parts meet all mandatory electrical, mechanical, and compliance requirements. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel) do not affect functional substitution when mounted in standard PCB applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS3216F685CS, CRCW12066M80FKEA, and RC1206FR-076M8L—are active production components with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on:

Samsung RCS3216F685CS: Primary choice when anti-sulfur and moisture-resistant properties are specified in design documentation. Suitable for general industrial applications requiring these specific protective features.

Vishay Dale CRCW12066M80FKEA: Qualified for automotive applications under AEC-Q200 standard. Select this part when automotive-grade reliability and qualification documentation are required by application specifications.

YAGEO RC1206FR-076M8L: Suitable for applications requiring moisture-resistant thick film construction. Offers highest inventory availability (23,460 units) among the three options.

All parts are electrically and mechanically interchangeable within standard PCB assembly processes. Physical dimension variations (maximum 0.006" length difference, 0.01" height difference) are within typical PCB design tolerances and do not affect circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW12066M80FKEA replace RCS3216F685CS in non-automotive applications?

A: Yes. The CRCW12066M80FKEA meets all electrical and mechanical parameters required for substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. All core specifications—resistance, tolerance, power rating, temperature range, and package—are identical.

Q: What is the significance of the dimension differences between RC1206FR-076M8L and the other parts?

A: The RC1206FR-076M8L has a length of 3.10mm compared to 3.20mm for the other parts, and a height of 0.65mm versus 0.66mm and 0.60mm respectively. These differences fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or circuit performance. Standard 1206 land patterns accommodate all three parts.

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 ±100ppm/°C temperature coefficient. Selection among them for high-temperature applications should be based on availability, cost, or specific manufacturer certifications rather than thermal performance differences.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. These parts can be stored indefinitely under normal conditions without degradation. This classification applies equally to all three substitute parts.

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

A: Yes. All three parts share the 1206 (3216 Metric) package with identical electrical specifications. Existing PCB designs, schematics, and assembly processes require no modification for substitution. Component placement and soldering procedures remain unchanged.

Q: Which part should be selected for cost optimization?

A: Cost comparison should be obtained from authorized distributors. YAGEO RC1206FR-076M8L shows highest inventory availability (23,460 units), which may provide cost advantages through volume availability and shorter lead times.
