RCS3216F2941CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F2941CS is a 2.94 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 with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is currently active in production with 688 pieces in stock inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization requires alternative sourcing, or when design specifications allow for functionally equivalent components from qualified manufacturers. All substitute parts listed maintain identical electrical specifications and package dimensions within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2941CS is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance value: 2.94 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All four substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length and height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but represent secondary differentiators for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

For new designs and ongoing production, select from parts with Active product status: AC1206FR-072K94L (YAGEO), CRCW12062K94FKEA (Vishay Dale), or RC1206FR-072K94L (YAGEO). These three parts are actively manufactured and supported by their respective suppliers.

Secondary Consideration:

ERJ-8ENF2941V (Panasonic) carries a "Not For New Designs" status and should be used only for replacement or maintenance of existing assemblies where design continuity is required. This part remains in inventory but is not recommended for new product development.

Compliance and Certifications:

All substitute parts maintain ROHS3 compliance and MSL 1 rating. AC1206FR-072K94L and CRCW12062K94FKEA include AEC-Q200 automotive qualification, which provides additional assurance for applications requiring automotive-grade reliability. RC1206FR-072K94L does not carry AEC-Q200 certification but meets all base electrical and environmental specifications.

Inventory Availability:

CRCW12062K94FKEA offers the highest inventory level (18,439 pieces), followed by RC1206FR-072K94L (21,509 pieces) and ERJ-8ENF2941V (15,210 pieces). AC1206FR-072K94L maintains 3,462 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-072K94L replace RCS3216F2941CS directly?

A: Yes. AC1206FR-072K94L meets all mandatory electrical and mechanical parameters: 2.94 kOhms ±1%, 0.25W, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The part is ROHS3 compliant with MSL 1 rating. Physical dimensions vary slightly (3.10mm length vs. 3.20mm), but both conform to 1206 package specification. AC1206FR-072K94L includes AEC-Q200 automotive certification, which the primary part does not specify.

Q: What is the difference between CRCW12062K94FKEA and RC1206FR-072K94L?

A: Both parts are electrically and thermally identical. CRCW12062K94FKEA (Vishay Dale) includes AEC-Q200 automotive qualification and is supplied in Cut Tape & Digi-Reel format. RC1206FR-072K94L (YAGEO) does not carry AEC-Q200 certification and is supplied in Tape & Reel format. Physical dimensions differ slightly: CRCW12062K94FKEA is 3.20mm length with 0.60mm maximum height; RC1206FR-072K94L is 3.10mm length with 0.65mm maximum height. Both are within 1206 package tolerance.

Q: Why is ERJ-8ENF2941V marked "Not For New Designs"?

A: ERJ-8ENF2941V carries a "Not For New Designs" status from Panasonic, indicating the manufacturer is phasing out this part number. The part remains functionally equivalent and available in inventory (15,210 pieces), but new product designs should select from actively supported alternatives: AC1206FR-072K94L, CRCW12062K94FKEA, or RC1206FR-072K94L. ERJ-8ENF2941V is suitable for replacement or maintenance of existing assemblies.

Q: Are all substitute parts available in the same packaging format?

A: No. AC1206FR-072K94L, ERJ-8ENF2941V, and RC1206FR-072K94L are supplied in Tape & Reel (TR) format. CRCW12062K94FKEA is supplied in Cut Tape (CT) & Digi-Reel format. Packaging format does not affect electrical performance but may impact procurement, handling, and assembly processes. Verify packaging compatibility with your supply chain and assembly equipment.

Q: Do all substitute parts have identical physical dimensions?

A: No. While all parts conform to the 1206 (3216 Metric) package specification, physical dimensions vary within tolerance:

• RCS3216F2941CS: 3.20mm L × 1.60mm W, 0.66mm max height
• AC1206FR-072K94L: 3.10mm L × 1.60mm W, 0.65mm max height
• CRCW12062K94FKEA: 3.20mm L × 1.60mm W, 0.60mm max height
• ERJ-8ENF2941V: 3.20mm L × 1.60mm W, 0.70mm max height
• RC1206FR-072K94L: 3.10mm L × 1.60mm W, 0.65mm max height

These variations are within 1206 package specification and do not affect PCB layout or assembly compatibility.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select AC1206FR-072K94L or CRCW12062K94FKEA, both of which carry AEC-Q200 automotive qualification. These parts meet automotive-grade reliability and performance standards. RC1206FR-072K94L does not specify AEC-Q200 certification and is suitable for general industrial applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part RCS3216F2941CS.
