RCS3216F4223CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F4223CS is a 422 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. The part is ROHS3 compliant and operates across the temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type, dimensions, termination count), and environmental ratings. Substitute components maintain identical or functionally equivalent performance parameters while potentially offering alternative sourcing, packaging options, or enhanced feature sets such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4223CS is determined by strict alignment with the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance: 422 kOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package Type: 1206 (3216 Metric)
• Number of Terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. bulk), and optional automotive certifications (AEC-Q200) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Applications):

• RC1206FR-07422KL (YAGEO): Active product status with moisture-resistant thick film composition. Suitable for general-purpose applications requiring long-term availability and standard industrial compliance.
• AC1206FR-07422KL (YAGEO): Active product status with automotive AEC-Q200 qualification. Recommended for automotive and high-reliability applications where AEC-Q200 certification is required or preferred.
• CRCW1206422KFKEA (Vishay Dale): Active product status with automotive AEC-Q200 qualification and highest inventory availability (16,061 pcs). Recommended for high-volume production and automotive applications.

Secondary Selection (Legacy Applications):

• ERJ-8ENF4223V (Panasonic): Classified as "Not For New Designs" but remains functionally equivalent with automotive AEC-Q200 qualification. Use only for replacement or maintenance of existing designs where this part number is already specified.

Original Manufacturer:

• RCS3216F4223CS (Samsung Electro-Mechanics): Maintains original specification with anti-sulfur and moisture-resistant features. Continue use where Samsung sourcing is contractually required or preferred.

Selection between substitute parts should be based on procurement requirements, supply chain strategy, and application-specific certifications rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F4223CS with AC1206FR-07422KL in automotive applications?

A: Yes. Both parts share identical electrical specifications (422 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), mechanical compatibility (1206 package, 2 terminations), and compliance ratings (ROHS3, MSL 1). AC1206FR-07422KL includes automotive AEC-Q200 qualification, making it suitable for automotive designs.

Q: What is the difference between RC1206FR-07422KL and AC1206FR-07422KL?

A: Both are manufactured by YAGEO with identical electrical and mechanical specifications. The primary difference is that AC1206FR-07422KL includes automotive AEC-Q200 qualification, while RC1206FR-07422KL is specified for general industrial applications. Physical dimensions vary slightly (AC: 3.10mm L vs. RC: 3.10mm L; both 1.60mm W), but both conform to 1206 package specifications.

Q: Why is ERJ-8ENF4223V marked as "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number for new applications. However, the part remains functionally equivalent and is suitable for replacement or maintenance of existing designs where it is already specified. New designs should prioritize parts with Active status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (RC1206FR-07422KL, AC1206FR-07422KL, CRCW1206422KFKEA, ERJ-8ENF4223V) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original RCS3216F4223CS specification.

Q: Can I use CRCW1206422KFKEA as a direct replacement in high-volume production?

A: Yes. CRCW1206422KFKEA is Active status with automotive AEC-Q200 qualification and the highest inventory availability (16,061 pcs). It meets all electrical, mechanical, and compliance requirements for direct substitution in high-volume applications.

Q: What packaging formats are available for these substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The original RCS3216F4223CS packaging format is not specified in the provided data but does not affect functional substitutability.

Q: Do these parts have different failure rates?

A: Failure rate data is not provided for any of the parts in this reference. Selection should be based on manufacturer reliability data sheets and application-specific requirements rather than this parameter.
