RCS3216F182CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F182CS is a 1.8 kOhms ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor 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 (Unlimited) rating and is currently in active production status with 811 pieces in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design requirements necessitate different power ratings or automotive certifications while maintaining the same electrical specifications.

Tolerance: ±1% (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Power rating: 0.25W minimum (equal or higher acceptable)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)

Engineering Selection Recommendations

Preferred Direct Equivalents (Identical Specifications):

AC1206FR-071K8L (YAGEO), CR1206-FX-1801ELF (Bourns Inc.), CRCW12061K80FKEA (Vishay Dale), and RC1206FR-071K8L (YAGEO) are direct electrical and mechanical equivalents to the RCS3216F182CS. All maintain 1.8 kOhms ±1% resistance, 0.25W power rating, 1206 package, and identical temperature specifications. All are ROHS3 compliant and in active production status. These parts are suitable for direct substitution in new designs and existing applications.

Functional Equivalent with Enhanced Power Rating:

CRCW12061K80FKEAHP (Vishay Dale) provides identical electrical specifications with an increased power rating of 0.75W (3/4W) in the same 1206 package. This part is suitable for applications requiring higher pulse withstanding capability or thermal margin while maintaining the same footprint and resistance value. ROHS3 compliance and active production status are confirmed.

Legacy Application Consideration:

ERJ-8ENF1801V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable only for legacy system maintenance, repair, or replacement in existing fielded equipment where continuity with original component specifications is required.

Compliance Restriction:

CRCW12061K80FKTA (Vishay Dale) is electrically and mechanically equivalent but is RoHS non-compliant and REACH affected. This part is restricted for use in applications subject to RoHS3 or REACH regulatory requirements and should not be selected for new designs or regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute AC1206FR-071K8L for RCS3216F182CS in my design?

A: Yes. AC1206FR-071K8L is a direct equivalent with identical resistance (1.8 kOhms ±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel vs. Bulk) and manufacturer (YAGEO vs. Samsung Electro-Mechanics).

Q: What is the difference between CRCW12061K80FKEA and CRCW12061K80FKEAHP?

A: Both parts are manufactured by Vishay Dale with identical resistance, tolerance, package, and temperature specifications. The key difference is power rating: CRCW12061K80FKEA is rated 0.25W (1/4W), while CRCW12061K80FKEAHP is rated 0.75W (3/4W). The higher power rating provides increased thermal capability and pulse withstanding performance in the same physical package. Selection depends on circuit power dissipation requirements.

Q: Why is ERJ-8ENF1801V marked "Not For New Designs"?

A: ERJ-8ENF1801V carries a "Not For New Designs" status from Panasonic, indicating the manufacturer is phasing out this product line. While electrically and mechanically equivalent to RCS3216F182CS, this part should be used only for maintenance and repair of existing equipment. New designs should select from active production alternatives such as AC1206FR-071K8L, CR1206-FX-1801ELF, or CRCW12061K80FKEA.

Q: Can I use CRCW12061K80FKTA as a substitute?

A: CRCW12061K80FKTA is electrically and mechanically equivalent but is RoHS non-compliant and REACH affected. Use is restricted to applications not subject to RoHS3 or REACH regulatory requirements. For RoHS3-compliant designs, select alternative parts such as AC1206FR-071K8L, CR1206-FX-1801ELF, or CRCW12061K80FKEA.

Q: Are all substitute parts available in the same package format?

A: No. RCS3216F182CS is supplied in Bulk packaging. Substitute parts are available in multiple formats: Tape & Reel (AC1206FR-071K8L, CR1206-FX-1801ELF, CRCW12061K80FKEAHP, CRCW12061K80FKTA, ERJ-8ENF1801V, RC1206FR-071K8L) and Cut Tape & Digi-Reel (CRCW12061K80FKEA). Packaging format selection depends on assembly process requirements and order quantity.

Q: Do all substitute parts have automotive certification?

A: No. AC1206FR-071K8L, CRCW12061K80FKEA, CRCW12061K80FKEAHP, CRCW12061K80FKTA, and ERJ-8ENF1801V carry AEC-Q200 automotive certification. RCS3216F182CS, CR1206-FX-1801ELF, and RC1206FR-071K8L do not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, select from the certified alternatives.

Q: What is the physical size difference between substitute parts?

A: All parts use the 1206 (3216 Metric) package with nominal dimensions of 3.20mm length × 1.60mm width. Minor variations in seated height exist: RCS3216F182CS (0.66mm), AC1206FR-071K8L (0.65mm), CR1206-FX-1801ELF (0.75mm), CRCW12061K80FKEA (0.60mm), CRCW12061K80FKEAHP (0.65mm), CRCW12061K80FKTA (0.60mm), ERJ-8ENF1801V (0.70mm), RC1206FR-071K8L (0.65mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.
