RCS3216F240CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F240CS is a 24 Ohm ±1% 0.25W (1/4W) thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status and features anti-sulfur and moisture-resistant construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package type, dimensions, termination count). Alternative sources become necessary for supply chain continuity, inventory availability, or application-specific requirements such as automotive qualification or enhanced pulse withstanding capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F240CS is determined by the following mandatory parameters:

Core Electrical Parameters:

• Resistance value: 24 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W) minimum
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance required
• MSL 1 (Unlimited) acceptable

All identified substitute parts meet these core parameters. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (automotive AEC-Q200 qualification, pulse withstanding capability), and minor dimensional tolerances do not disqualify substitution but may introduce application-specific considerations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-0724RL (YAGEO), CR1206-FX-24R0ELF (Bourns Inc.), CRCW120624R0FKEA (Vishay Dale), and RC1206FR-0724RL (YAGEO) are direct electrical and mechanical equivalents to the RCS3216F240CS. All maintain Active product status and ROHS3 compliance. These parts are suitable for new designs and ongoing production.

Automotive-Qualified Alternatives:

AC1206FR-0724RL, CRCW120624R0FKEA, and CRCW120624R0FKEAHP carry AEC-Q200 automotive qualification. These parts are appropriate for applications requiring automotive-grade component certification.

Enhanced Power Rating Option:

CRCW120624R0FKEAHP provides 0.75W (3/4W) power rating with pulse withstanding capability while maintaining the 24 Ohm resistance and ±1% tolerance. This part is suitable for applications requiring higher transient power dissipation within the 1206 package footprint.

Legacy Status Consideration:

ERJ-8ENF24R0V (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically and mechanically equivalent, this part is not recommended for new product development. Use only for replacement or maintenance of existing systems.

Frequently Asked Questions (FAQ)

Q: Can CRCW120624R0FKEAHP (0.75W) be used as a direct replacement for RCS3216F240CS (0.25W)?

A: Yes. The CRCW120624R0FKEAHP maintains identical resistance (24 Ohms), tolerance (±1%), package (1206), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W vs. 0.25W) provides additional thermal margin and does not create incompatibility. Physical dimensions remain within acceptable tolerances for PCB assembly.

Q: Are there packaging format restrictions for substitution?

A: No. Tape & Reel (TR), Cut Tape (CT), and Digi-Reel formats are interchangeable from an electrical and mechanical standpoint. Packaging format selection depends on assembly process requirements and inventory management practices, not component functionality.

Q: What is the significance of AEC-Q200 qualification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts carrying this certification (AC1206FR-0724RL, CRCW120624R0FKEA, CRCW120624R0FKEAHP, ERJ-8ENF24R0V) have undergone additional reliability testing. Use AEC-Q200 qualified parts in automotive applications or systems requiring automotive-grade component assurance.

Q: Why is ERJ-8ENF24R0V marked "Not For New Designs"?

A: This product status indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. ERJ-8ENF24R0V remains available for replacement and maintenance applications but should not be selected for new development projects.

Q: Are dimensional variations between substitute parts significant?

A: Minor dimensional variations exist within the 1206 package specification. All listed substitutes conform to the 1206 (3216 Metric) standard. Height variations (0.024" to 0.030" seated maximum) fall within PCB assembly tolerances and do not affect functionality or compatibility.

Q: Can substitute parts be mixed within a single assembly?

A: Yes. All substitute parts meet identical electrical specifications (24 Ohms ±1%, 0.25W minimum, ±100ppm/°C, -55°C ~ 155°C). Mixed sourcing from multiple manufacturers is electrically and mechanically compatible within a single PCB assembly.
