RCS3216F243CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F243CS is a 24 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 properties. The part operates across -55°C to 155°C temperature range and complies with ROHS3 standards.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or enhanced power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F243CS is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• Resistance value: 24 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power Rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant

Secondary Considerations:

• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Automotive certification (AEC-Q200) when specified by design requirements

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the primary component. Dimensional variations within supplier tolerances do not affect PCB assembly or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

For applications requiring automotive AEC-Q200 certification, select from:

• AC1206FR-0724KL (YAGEO) - Active status, AEC-Q200 qualified, 10,552 units in stock
• CRCW120624K0FKEA (Vishay Dale) - Active status, AEC-Q200 qualified, 25,100 units in stock
• CRCW120624K0FKEAHP (Vishay Dale) - Active status, AEC-Q200 qualified, enhanced 0.75W power rating, 10,712 units in stock

For applications without automotive certification requirements, select from:

• CR1206-FX-2402ELF (Bourns Inc.) - Active status, 25,789 units in stock
• RC1206FR-0724KL (YAGEO) - Active status, highest inventory availability at 140,347 units

Not Recommended for New Designs:

ERJ-8ENF2402V (Panasonic Electronic Components) carries "Not For New Designs" product status designation. This part is electrically and mechanically compatible but should not be selected for new circuit designs due to manufacturer lifecycle status.

Power Rating Consideration:

CRCW120624K0FKEAHP provides 0.75W power rating compared to the standard 0.25W specification. This higher rating is suitable for applications requiring enhanced thermal margin but does not affect electrical compatibility in circuits designed for 0.25W operation.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F243CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical resistance (24 kOhms), tolerance (±1%), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct substitution on PCB assembly is mechanically and electrically compatible.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing and traceability requirements. Parts with AEC-Q200 (AC1206FR-0724KL, CRCW120624K0FKEA, CRCW120624K0FKEAHP, ERJ-8ENF2402V) are suitable for automotive applications. Parts without AEC-Q200 (RCS3216F243CS, CR1206-FX-2402ELF, RC1206FR-0724KL) are suitable for industrial and consumer applications.

Q: Why is ERJ-8ENF2402V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. While the part remains electrically compatible and is currently in stock, it should not be selected for new product development.

Q: What is the significance of the CRCW120624K0FKEAHP having 0.75W power rating?

A: The 0.75W rating provides three times the power dissipation capability compared to the standard 0.25W specification. This part is suitable for circuits requiring higher thermal margin or operating in elevated ambient temperature conditions. It is fully compatible with circuits designed for 0.25W operation.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within supplier tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width is consistent at 0.063" (1.60mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within PCB assembly process tolerances and do not affect functionality or placement.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-0724KL (YAGEO) has the highest inventory at 140,347 units in stock, followed by CR1206-FX-2402ELF (Bourns Inc.) at 25,789 units and CRCW120624K0FKEA (Vishay Dale) at 25,100 units.

Q: Can I use CRCW120624K0FKEAHP as a direct replacement in all applications?

A: Yes. The higher 0.75W power rating is backward compatible with circuits designed for 0.25W operation. The part occupies the same 1206 package footprint and maintains all other electrical specifications.
