RCS3216J222CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J222CS is a 2.2 kOhms ±5% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status with 995 pieces in stock.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, specific feature requirements such as automotive qualification, improved tolerance specifications, or enhanced power ratings while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the RCS3216J222CS is determined by strict adherence to the following core parameters:

Mandatory Compatibility Parameters:

Resistance value: 2.2 kOhms (exact match required)
Package format: 1206 (3216 Metric) (physical and electrical compatibility)
Composition: Thick Film (material consistency)
Temperature coefficient: ±100ppm/°C (thermal stability equivalence)
Operating temperature range: -55°C to 155°C (environmental specification match)
RoHS3 compliance and MSL 1 rating (regulatory and handling consistency)

Allowable Variation Parameters:

Tolerance: ±5% (primary specification) or ±1% (tighter tolerance acceptable for direct substitution)
Power rating: 0.25W (primary specification) or 0.75W (higher rating acceptable for direct substitution)
Manufacturer: Multiple qualified manufacturers acceptable
Packaging format: Tape & Reel or Cut Tape formats interchangeable
Additional features: Automotive AEC-Q200 qualification, pulse withstanding capability, or enhanced moisture resistance are supplementary features that do not preclude substitution

Substitute parts are grouped into two categories: Direct Equivalents (matching tolerance and power rating) and Enhanced Specifications (improved tolerance or power rating with identical core parameters).

Engineering Selection Recommendations

Direct Equivalents (±5% Tolerance, 0.25W):

AC1206JR-072K2L and RC1206JR-072K2L from YAGEO are direct functional equivalents to RCS3216J222CS. Both maintain identical electrical specifications (2.2 kOhms ±5%, 0.25W) and package format. AC1206JR-072K2L includes automotive AEC-Q200 qualification. Both parts are in active production status with substantial inventory availability (6806 and 111533 pieces respectively).

Enhanced Tolerance Substitutes (±1% Tolerance, 0.25W):

AC1206FR-072K2L, CR1206-FX-2201ELF, CRCW12062K20FKEA, KTR18EZPF2201, and RC1206FR-072K2L provide improved tolerance specification (±1%) while maintaining 0.25W power rating and 1206 package format. These parts are suitable for applications requiring tighter resistance tolerance. All are ROHS3 compliant with MSL 1 rating and active production status. AC1206FR-072K2L, CRCW12062K20FKEA, and KTR18EZPF2201 include automotive AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216J222CS with a ±1% tolerance part?

A: Yes. Parts with ±1% tolerance (AC1206FR-072K2L, CR1206-FX-2201ELF, CRCW12062K20FKEA, KTR18EZPF2201, RC1206FR-072K2L) are direct substitutes. The tighter tolerance specification is compatible with applications designed for ±5% tolerance. No circuit redesign is required.

Q: Are all substitute parts physically identical?

A: All substitute parts use the 1206 (3216 Metric) package format with identical electrical footprint. Physical dimensions vary slightly: most measure 0.122" to 0.126" length and 0.063" width. Height ranges from 0.024" to 0.030" seated maximum. These variations are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: Which substitute parts have automotive qualification?

A: AC1206JR-072K2L, AC1206FR-072K2L, CRCW12062K20FKEA, CRCW12062K20FKEAHP, ERJ-8ENF2201V, and KTR18EZPF2201 carry AEC-Q200 automotive qualification. Selection of AEC-Q200 qualified parts is required for automotive applications.

Q: Can I use CRCW12062K20FKEAHP (0.75W) in place of RCS3216J222CS (0.25W)?

A: Yes. The higher power rating (0.75W) is compatible with applications designed for 0.25W. The part provides additional thermal margin and pulse withstanding capability. No circuit modification is necessary. The 1206 package accommodates the higher power rating without dimensional conflicts.

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

A: Both packaging formats contain identical components. Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel packaging provides the same components in shorter tape lengths or individual reels. Selection depends on assembly process requirements and order quantity. Electrical and mechanical specifications are identical.

Q: Why is ERJ-8ENF2201V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. The part remains available for existing production and legacy system support. For new designs, select from active status alternatives such as KTR18EZPF2201, AC1206FR-072K2L, or RC1206FR-072K2L.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of RCS3216J222CS. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Which substitute has the highest inventory availability?

A: RC1206FR-072K2L from YAGEO has the highest inventory with 167335 pieces in stock, followed by RC1206JR-072K2L with 111533 pieces. Both are active production parts with immediate availability.
