RCS3216F515CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F515CS is a 5.1 MOhm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative qualified sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F515CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.1 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All four substitute parts listed meet these mandatory parameters. Dimensional variations within the 1206 package specification and additional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution but represent enhanced feature sets available from alternative manufacturers.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS3216F515CS based on electrical specifications and package compatibility. Selection among these alternatives should be based on the following criteria:

AC1206FR-075M1L (YAGEO): This part carries AEC-Q200 automotive qualification and is available in Tape & Reel packaging. It is suitable for applications requiring automotive-grade reliability with high inventory availability (10,867 pcs).

CRCW12065M10FKEA (Vishay Dale): This part provides AEC-Q200 automotive qualification and maintains identical dimensional specifications to the main part. It is appropriate for automotive and industrial applications with moderate inventory levels (4,233 pcs).

KTR18EZPF5104 (Rohm Semiconductor): This part combines AEC-Q200 automotive qualification with high-voltage capability. It offers the highest inventory availability (24,263 pcs) and is suitable for applications requiring enhanced voltage performance within the specified operating parameters.

RC1206FR-075M1L (YAGEO): This part provides moisture-resistant characteristics without automotive certification and is available in Cut Tape and Digi-Reel packaging formats. It is suitable for general industrial applications with high inventory availability (10,378 pcs).

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-075M1L replace RCS3216F515CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (5.1 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and the same 1206 package footprint. Dimensional variations (3.10mm vs 3.20mm length) fall within standard 1206 package tolerances and do not affect PCB placement or soldering.

Q: What is the difference between the YAGEO AC1206FR-075M1L and RC1206FR-075M1L?

A: The AC1206FR-075M1L includes AEC-Q200 automotive qualification and is supplied in Tape & Reel format. The RC1206FR-075M1L lacks automotive certification and is supplied in Cut Tape and Digi-Reel formats. Both share identical electrical performance and moisture-resistant characteristics.

Q: Is KTR18EZPF5104 suitable for non-automotive applications?

A: Yes. The KTR18EZPF5104 meets all electrical and mechanical requirements for the RCS3216F515CS. The AEC-Q200 automotive qualification and high-voltage capability represent additional features that do not restrict use in general industrial or consumer applications.

Q: Do all substitute parts require the same storage and handling conditions?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard ESD precautions and room-temperature storage apply uniformly across all listed parts.

Q: Can packaging format (Tape & Reel vs Cut Tape) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and assembly line compatibility. Electrical and mechanical performance of the resistor element is independent of packaging format.

Q: Are there dimensional constraints that would prevent substitution?

A: No. All parts conform to the 1206 (3216 Metric) package specification. Maximum height variations (0.60mm to 0.66mm) and length variations (3.10mm to 3.20mm) remain within standard package tolerances and do not affect PCB assembly or component clearance.
