RCS3216F1273CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1273CS is a 127 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 status and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package type, dimensions, termination count) match the main part. Substitutes may differ in specific features (such as automotive qualification) or product status, which are documented for engineering selection purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict matching of the following parameters:

Core Electrical Parameters:

• Resistance value: 127 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Core Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

All four substitute parts listed meet these core criteria. Variations in features (such as automotive AEC-Q200 qualification for AC1206FR-07127KL, CRCW1206127KFKEA, and ERJ-8ENF1273V) and product status do not disqualify substitution but are noted for application-specific requirements. Minor dimensional variations within the 1206 package specification are acceptable.

Parameter Comparison

Engineering Selection Recommendations

AC1206FR-07127KL (YAGEO): Active product status with AEC-Q200 automotive qualification. Suitable for applications requiring automotive-grade components. Dimensions 3.10mm x 1.60mm with 0.65mm seated height.

CRCW1206127KFKEA (Vishay Dale): Active product status with AEC-Q200 automotive qualification. Dimensions 3.20mm x 1.60mm with 0.60mm seated height. Lowest seated height among substitutes.

ERJ-8ENF1273V (Panasonic): Product status is "Not For New Designs." This part is suitable only for legacy system maintenance or replacement in existing applications. AEC-Q200 automotive qualified. Dimensions 3.20mm x 1.60mm with 0.70mm seated height.

RC1206FR-07127KL (YAGEO): Active product status without automotive qualification. Suitable for general industrial and consumer applications. Dimensions 3.10mm x 1.60mm with 0.65mm seated height.

All substitutes are ROHS3 compliant and REACH unaffected, matching the main part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07127KL replace RCS3216F1273CS in any application?

A: AC1206FR-07127KL meets all core electrical and mechanical specifications. The primary difference is AEC-Q200 automotive qualification, which the main part does not carry. Substitution is valid for electrical performance; application requirements determine if automotive qualification is necessary.

Q: What is the significance of "Not For New Designs" status for ERJ-8ENF1273V?

A: This designation indicates the manufacturer does not recommend this part for new product development. It remains suitable for replacement in existing systems or legacy applications where the part is already in use. New designs should select from Active status alternatives.

Q: Are dimensional variations between substitutes significant?

A: All substitutes conform to the 1206 (3216 Metric) package specification. Seated height variations (0.60mm to 0.70mm) fall within standard package tolerances and do not affect electrical performance. PCB layout and assembly processes accommodate these variations.

Q: Does the absence of AEC-Q200 in RC1206FR-07127KL affect substitution validity?

A: RC1206FR-07127KL is electrically and mechanically equivalent to RCS3216F1273CS. AEC-Q200 is an additional qualification not present in the main part. Substitution is valid for non-automotive applications; automotive applications should specify AEC-Q200 qualified alternatives.

Q: Can these substitutes be used interchangeably in existing designs?

A: Yes, all four substitutes are electrically and mechanically interchangeable with RCS3216F1273CS based on matching core parameters. Procurement should verify availability and lead times, as inventory levels vary by manufacturer and distributor.

Q: What packaging format is standard for these substitutes?

A: All substitutes are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The main part RCS3216F1273CS packaging format is not specified in the provided data.
