RCS3216F4754CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F4754CS is a 4.75 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 construction, 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. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when specific application requirements necessitate alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4754CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.75 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length and height), packaging format (Tape & Reel vs. bulk), and supplementary features (such as automotive qualification) do not disqualify substitution when core electrical and thermal specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS3216F4754CS, CRCW12064M75FKEA, and RC1206FR-074M75L—are electrically and thermally equivalent and suitable for direct substitution in applications requiring a 4.75 MOhms ±1% 1/4W 1206 chip resistor.

Selection Criteria Based on Provided Data:

RCS3216F4754CS (Samsung Electro-Mechanics): Primary choice when anti-sulfur protection is a specified requirement. Active product status with 863 units in stock. ROHS3 compliant, MSL 1 rated.

CRCW12064M75FKEA (Vishay Dale): Suitable for automotive applications requiring AEC-Q200 qualification. Active product status with 17,517 units in stock. Tape & Reel packaging supports high-volume assembly. ROHS3 compliant, MSL 1 rated.

RC1206FR-074M75L (YAGEO): Moisture-resistant construction aligns with general industrial applications. Active product status with 5,397 units in stock. Tape & Reel packaging. ROHS3 compliant, MSL 1 rated.

All parts carry identical electrical specifications, temperature performance, and regulatory compliance. Selection should be based on packaging requirements (bulk vs. Tape & Reel), application-specific certifications (automotive AEC-Q200 for CRCW12064M75FKEA), and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW12064M75FKEA replace RCS3216F4754CS in any application?

A: Yes. Both parts share identical electrical specifications (4.75 MOhms ±1%), power rating (0.25W), package (1206), temperature range (-55°C ~ 155°C), and regulatory compliance (ROHS3, MSL 1). The primary difference is packaging format (Tape & Reel vs. bulk) and the addition of AEC-Q200 automotive qualification on the Vishay part, which does not restrict its use in non-automotive applications.

Q: What is the significance of the AEC-Q200 rating on CRCW12064M75FKEA?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the part has undergone additional reliability testing for automotive environments. For non-automotive applications, this certification provides no restriction and may offer additional confidence in reliability margins.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist. RCS3216F4754CS and RC1206FR-074M75L have maximum seated heights of 0.66mm and 0.65mm respectively, while CRCW12064M75FKEA is 0.60mm. Length dimensions vary slightly (3.20mm, 3.10mm, and 3.20mm respectively). These differences are within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which part should be selected for high-volume production?

A: CRCW12064M75FKEA is supplied in Tape & Reel format with the highest inventory (17,517 units), making it optimal for automated assembly and high-volume manufacturing. RC1206FR-074M75L is also available in Tape & Reel format (5,397 units). RCS3216F4754CS is available in bulk format (863 units).

Q: Are all three parts REACH compliant?

A: Yes. All three parts carry REACH Unaffected status, indicating they are not subject to REACH substance restrictions.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: All three parts meet identical electrical, thermal, and regulatory specifications. Interchangeability is supported by parameter equivalence. Design re-qualification is not required based on the provided technical data.
