RCS3216J201CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J201CS is a 200 Ohm ±5% 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 with unlimited moisture sensitivity level (MSL 1) and operates across -55°C to 155°C temperature range.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count, operating temperature range). Substitute parts may offer enhanced features such as automotive AEC-Q200 qualification, improved tolerance grades, or higher power ratings within the same physical package envelope.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

AC1206JR-07200RL and RC1206JR-07200RL are direct functional equivalents to RCS3216J201CS, matching the ±5% tolerance and 0.25W power rating. Both parts are ROHS3 compliant and Active product status. AC1206JR-07200RL offers higher inventory availability (5357 pcs) in Tape & Reel packaging. RC1206JR-07200RL is available in Cut Tape & Digi-Reel format with lower inventory (1480 pcs).

For Enhanced Tolerance Applications:

AC1206FR-07200RL, CR1206-FX-2000ELF, CRCW1206200RFKEA, and RC1206FR-07200RL provide ±1% tolerance within the same 0.25W power rating and 1206 package. These parts are suitable for applications requiring tighter resistance tolerance. All are ROHS3 compliant and Active status. CR1206-FX-2000ELF offers the highest inventory (124297 pcs).

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a substitute for the ±5% RCS3216J201CS?

A: Yes. Tighter tolerance (±1%) is electrically superior and functionally compatible. The part will perform within the original ±5% specification window while providing better accuracy. No circuit redesign is required.

Q: Are all substitute parts mechanically compatible with the 1206 package footprint?

A: Yes. All listed substitutes use the 1206 (3216 Metric) package with identical termination count (2) and operating temperature range (-55°C ~ 155°C). Physical dimensions vary slightly within the 1206 envelope (length 3.10mm to 3.20mm, width 1.60mm, height 0.60mm to 0.75mm), but all are compatible with standard 1206 PCB footprints.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape in reel format, suitable for automated assembly equipment. Cut Tape & Digi-Reel is supplied in shorter tape segments, suitable for manual assembly or lower-volume production. Both formats contain identical components; packaging choice depends on assembly process requirements.

Q: Can I use CRCW1206200RFKEAHP (0.75W) instead of the 0.25W RCS3216J201CS?

A: Yes. Higher power rating provides thermal derating margin and is electrically compatible. The 0.75W part will operate cooler in the same application. Use this substitution when thermal performance or pulse current handling is a design consideration. No circuit modification is required.

Q: Why is ERJ-8ENF2000V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. While the part remains available in inventory (66277 pcs), it should not be selected for new designs due to potential future availability constraints.

Q: Are all substitute parts RoHS3 compliant?

A: No. CRCW1206200RFKTA is RoHS non-compliant. All other listed substitutes are ROHS3 compliant. For applications requiring RoHS3 compliance, exclude CRCW1206200RFKTA from selection.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics qualification standard. Parts carrying this rating have passed automotive-grade reliability testing and are suitable for automotive applications. Non-automotive parts (RCS3216J201CS, CR1206-FX-2000ELF, RC1206FR-07200RL, RC1206JR-07200RL) lack this qualification but remain suitable for general industrial and consumer applications.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes. All substitute parts meet the same electrical specifications (200 Ohms, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and mechanical compatibility (1206 package, 2 terminations). Mixed sourcing is acceptable from a functional standpoint. Verify procurement and supply chain requirements with your supplier.
