RCS3216F2101CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F2101CS is a 2.1 kOhms ±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 with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental ratings to ensure direct functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2101CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• Resistance value: 2.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) nominal (minor height variations acceptable within manufacturing tolerances)

Compliance & Environmental:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All substitute parts listed meet these criteria and are therefore directly interchangeable with the RCS3216F2101CS in circuit applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The CR1206-FX-2101ELF (Bourns Inc.), CRCW12062K10FKEA (Vishay Dale), and RC1206FR-072K1L (YAGEO) are all Active products with identical electrical specifications and full ROHS3 compliance. These three parts are functionally equivalent to the RCS3216F2101CS and suitable for new designs and production applications. All three maintain the required operating temperature range, tolerance, and power rating specifications.

Secondary Substitute (Legacy Status):

The ERJ-8ENF2101V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable only for replacement or maintenance applications where the original part specification must be maintained. It should not be selected for new circuit designs.

Packaging Considerations:

The RCS3216F2101CS is supplied in standard packaging format. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats depending on manufacturer. Verify packaging format compatibility with assembly equipment and procurement requirements before final selection.

Automotive Applications:

The CRCW12062K10FKEA and ERJ-8ENF2101V include AEC-Q200 automotive qualification ratings. If the application requires automotive-grade components, these two options provide additional certification. The RCS3216F2101CS, CR1206-FX-2101ELF, and RC1206FR-072K1L do not carry explicit automotive ratings but remain compliant with general industrial specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F2101CS with any of the listed equivalent parts without circuit modification?

A: Yes. All listed substitute parts match the critical electrical parameters (2.1 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (1206 package, 2 terminations). Direct substitution is possible without design changes. However, verify product status for your application type (new design vs. replacement).

Q: What is the difference between the substitute parts?

A: All substitute parts are electrically and mechanically identical. The primary differences are: (1) manufacturer identity, (2) product status (Active vs. Not For New Designs), (3) packaging format (Tape & Reel vs. Cut Tape), (4) seated height tolerance (ranging from 0.024" to 0.030"), and (5) automotive certification (AEC-Q200 available for Vishay Dale and Panasonic options).

Q: Why is the ERJ-8ENF2101V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued this product for new applications. While the part remains functionally equivalent and available in inventory, it should only be used for replacement or maintenance of existing assemblies. For new circuit designs, select from the Active status alternatives: CR1206-FX-2101ELF, CRCW12062K10FKEA, or RC1206FR-072K1L.

Q: Are there any height differences that could affect PCB assembly?

A: Yes. Seated heights vary slightly: RCS3216F2101CS (0.66mm), CR1206-FX-2101ELF (0.75mm), CRCW12062K10FKEA (0.60mm), ERJ-8ENF2101V (0.70mm), and RC1206FR-072K1L (0.65mm). These variations are within standard 1206 package tolerances and do not affect electrical performance. Verify with your PCB design and assembly process if height-critical applications exist (such as low-profile designs or confined spaces).

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

A: Yes. All parts, including the RCS3216F2101CS and all substitutes, carry MSL 1 (Unlimited) rating. This means they have unlimited shelf life and do not require special moisture control during storage or handling.

Q: Which substitute should I choose for automotive applications?

A: If AEC-Q200 automotive qualification is required, select either CRCW12062K10FKEA (Vishay Dale) or ERJ-8ENF2101V (Panasonic). The CRCW12062K10FKEA is preferred for new automotive designs due to its Active product status. The ERJ-8ENF2101V is suitable only for replacement applications in existing automotive assemblies.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the RCS3216F2101CS and all four substitute options, are ROHS3 compliant and REACH Unaffected. They meet current environmental and regulatory requirements for commercial and industrial applications.
