Substitute Part Grouping Explanation

Substitute parts for RCS3216J182CS are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Resistance Value: 1.8 kOhms (exact match required)
Package / Case: 1206 (3216 Metric) (mechanical compatibility)
Power Rating: 0.25W minimum (electrical stress rating)
Temperature Coefficient: ±100ppm/°C (thermal stability)
Operating Temperature Range: -55°C ~ 155°C (environmental compatibility)
Composition: Thick Film (material consistency)
Terminations: 2 (circuit connection points)

Secondary Considerations:

Tolerance: ±5% or tighter (±1%) acceptable for improved accuracy
RoHS Compliance: ROHS3 Compliant preferred for regulatory alignment
Moisture Sensitivity Level: 1 (Unlimited) for handling consistency
Product Status: Active preferred; Not For New Designs acceptable for existing designs

Substitutes with tolerance ±1% provide superior accuracy while maintaining full electrical and mechanical compatibility. Substitutes with higher power ratings (0.75W) remain compatible as they operate within the same thermal envelope. Automotive-rated variants (AEC-Q200) are included where applicable, indicating enhanced reliability qualification.

Q: Why is CRCW12061K80FKTA marked RoHS non-compliant?

A: CRCW12061K80FKTA is RoHS non-compliant and REACH Affected. Use only in applications where legacy compliance status is acceptable or where regulatory exemptions apply. For new designs, select ROHS3 Compliant alternatives.

Q: Is ERJ-8ENF1801V suitable for new designs?

A: ERJ-8ENF1801V carries "Not For New Designs" status. Use only for replacement or maintenance of existing designs. For new designs, select Active status alternatives such as AC1206FR-071K8L, CR1206-FX-1801ELF, or CRCW12061K80FKEA.

Q: Do all substitutes have identical physical dimensions?

A: Dimensions are functionally equivalent within 1206 package specification. Minor variations exist: RCS3216J182CS and CR1206-FX-1801ELF measure 0.126" L × 0.063" W; YAGEO and some Vishay variants measure 0.122" L × 0.063" W. All fit standard 1206 footprints without layout modification.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates the component requires no special moisture protection during storage or handling. All listed substitutes carry MSL 1, ensuring consistent handling procedures.
