RC3216F274CS Equivalent & Substitute Parts

Part Overview

The RC3216F274CS is a 270 kOhms ±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 and is designed for general-purpose applications requiring moisture-resistant thick film construction. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements necessitate alternative manufacturer options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the RC3216F274CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Resistance value: 270 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)
Composition: Thick Film (exact match required)
Number of terminations: 2 (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance Parameters:

RoHS3 Compliance (required for all substitutes)

All substitute parts listed meet these criteria. Dimensional variations within the 1206 package specification are acceptable as they fall within standard PCB footprint tolerances. Additional features such as Automotive AEC-Q200 certification or High Voltage capability represent enhanced specifications and do not prevent substitution for applications not requiring these certifications.

Engineering Selection Recommendations

Active Product Status Substitutes: CR1206-FX-2703ELF (Bourns), CRG1206F270K (TE Connectivity), RC1206FR-07270KL (YAGEO), RMCF1206FT270K (Stackpole), AC1206FR-07270KL (YAGEO), CRCW1206270KFKEA (Vishay Dale), and KTR18EZPF2703 (Rohm) are all classified as Active products and are suitable for new designs and ongoing production applications.

Discontinued Product Status: ERJ-8ENF2703V (Panasonic) carries a "Not For New Designs" status and MCR18ERTF2703 (Rohm) is discontinued at DiGi Electronics. These parts are electrically and mechanically equivalent but should not be selected for new design implementations.

Compliance Considerations: All listed substitutes maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and environmental requirements.

Automotive Certification: Several substitutes carry Automotive AEC-Q200 certification (ERJ-8ENF2703V, RMCF1206FT270K, AC1206FR-07270KL, CRCW1206270KFKEA, KTR18EZPF2703). This certification is an enhanced specification and does not restrict substitution for non-automotive applications. For automotive applications, these certified parts provide additional qualification assurance.

High Voltage Feature: KTR18EZPF2703 includes High Voltage capability as an enhanced feature. This does not prevent its use in standard applications and represents an additional design margin.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC3216F274CS with any of the listed parts without PCB redesign?

A: Yes. All listed substitute parts share identical electrical specifications (270 kOhms, ±1%, 0.25W) and are packaged in the standard 1206 (3216 Metric) footprint. Dimensional variations within the 1206 package specification are within PCB footprint tolerances and do not require layout modifications.

Q: What is the difference between parts marked "Active" and "Not For New Designs"?

A: Parts marked "Active" are currently in production and recommended for new designs. ERJ-8ENF2703V is marked "Not For New Designs," indicating it is in mature phase or transitioning out of production. MCR18ERTF2703 is discontinued at DiGi Electronics. These parts remain electrically equivalent but should not be selected for new product development.

Q: Do I need to select an AEC-Q200 certified part for my application?

A: AEC-Q200 certification is required only for automotive applications. For general-purpose, industrial, or consumer applications, non-certified parts such as CR1206-FX-2703ELF or CRG1206F270K are fully suitable. Selection should be based on application requirements, not on the presence of automotive certification.

Q: What does MSL Level 1 mean?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life and no special moisture control requirements during storage or handling. All listed parts carry MSL Level 1, eliminating the need for dry-pack storage or baking procedures prior to assembly.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. For example, length ranges from 0.120" to 0.126" and height from 0.024" to 0.030". These variations fall within standard PCB footprint tolerances and do not affect assembly or functionality.

Q: Which substitute part has the highest inventory availability?

A: KTR18EZPF2703 (Rohm Semiconductor) has the highest inventory with 199,386 pieces in stock. CR1206-FX-2703ELF (Bourns) has 25,759 pieces, and CRCW1206270KFKEA (Vishay Dale) has 15,769 pieces. Inventory levels should be verified with your supplier for current availability.

Q: Can I use MCR18ERTF2703 in my design?

A: MCR18ERTF2703 is electrically and mechanically equivalent but is discontinued at DiGi Electronics. It should not be selected for new designs due to uncertain long-term availability. Active alternatives such as KTR18EZPF2703, CRCW1206270KFKEA, or RC1206FR-07270KL are recommended.

Q: What packaging options are available for substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) packaging. MCR18ERTF2703 is available in Cut Tape (CT) & Digi-Reel® packaging. Packaging selection depends on production volume and assembly equipment compatibility.
