RCS3216F910CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F910CS is a 91 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component features anti-sulfur and moisture-resistant properties, operating across the temperature range of -55°C to 155°C. The part is currently in active production status with 977 pieces available in new original inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed for production resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F910CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 91 Ohms
• 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
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. other formats), 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 Substitutes (Active Product Status):

AC1206FR-0791RL, CRCW120691R0FKEA, and RC1206FR-0791RL are all active production parts meeting all mandatory electrical and mechanical parameters. AC1206FR-0791RL and CRCW120691R0FKEA carry AEC-Q200 automotive qualification, which provides additional assurance for applications requiring automotive-grade reliability. RC1206FR-0791RL offers moisture-resistant properties aligned with the original RCS3216F910CS specification.

Secondary Substitute (Legacy Status):

ERJ-8ENF91R0V is marked as "Not For New Designs" and should be used only for replacement or maintenance of existing assemblies. While electrically and mechanically equivalent, this part is not recommended for new product development.

Inventory Considerations:

CRCW120691R0FKEA offers the highest inventory availability at 28,030 pieces, followed by RC1206FR-0791RL at 35,103 pieces and ERJ-8ENF91R0V at 68,824 pieces. These inventory levels support high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-0791RL be used as a direct replacement for RCS3216F910CS?

A: Yes. AC1206FR-0791RL meets all mandatory electrical parameters (91 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package specifications (1206 / 3216 Metric). The AEC-Q200 automotive certification is an additional qualification that does not prevent substitution in non-automotive applications.

Q: What is the difference between the YAGEO AC1206FR-0791RL and RC1206FR-0791RL?

A: Both parts are manufactured by YAGEO and meet identical electrical specifications. AC1206FR-0791RL carries AEC-Q200 automotive qualification and moisture-resistant properties. RC1206FR-0791RL is specified as moisture-resistant without automotive certification. Both are suitable substitutes for the RCS3216F910CS.

Q: Why is ERJ-8ENF91R0V marked "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this product line and is not recommending it for new product development. However, the part remains electrically and mechanically equivalent and is suitable for replacement applications or existing design maintenance.

Q: Are there physical dimension differences between these substitute parts?

A: Minor variations exist within the 1206 package specification. RCS3216F910CS and CRCW120691R0FKEA measure 0.126" L × 0.063" W, while AC1206FR-0791RL and RC1206FR-0791RL measure 0.122" L × 0.063" W. Height variations range from 0.024" to 0.028" seated maximum. These differences remain within 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best supply chain stability?

A: CRCW120691R0FKEA from Vishay Dale offers the highest inventory level (28,030 pieces) combined with active product status and AEC-Q200 certification, providing strong supply chain assurance for production planning.

Q: Can these parts be used interchangeably in automotive applications?

A: AC1206FR-0791RL and CRCW120691R0FKEA both carry AEC-Q200 automotive qualification. RCS3216F910CS, RC1206FR-0791RL, and ERJ-8ENF91R0V do not specify automotive certification. Application requirements should determine whether AEC-Q200 qualification is mandatory.
