Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F18R2CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 18.2 Ohms with ±1% tolerance and 0.25W power rating must be maintained across all substitutes.

Package Compatibility: All substitute parts must use 1206 (3216 Metric) surface mount package format to ensure PCB footprint compatibility without layout modifications.

Environmental Performance: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C define the thermal performance envelope.

Regulatory Compliance: ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for substitution eligibility.

Composition: Thick film construction is required to maintain electrical and thermal characteristics.

Three qualified substitute parts meet these criteria: CRCW120618R2FKEA (Vishay Dale), ERJ-8ENF18R2V (Panasonic Electronic Components), and RC1206FR-0718R2L (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

CRCW120618R2FKEA (Vishay Dale): This substitute maintains Active product status with full electrical and mechanical equivalence to the RCS3216F18R2CS. The part includes Automotive AEC-Q200 qualification, providing enhanced reliability documentation. Seated height of 0.024" (0.60mm) is within acceptable PCB assembly tolerances. Inventory availability of 39624 pieces supports production requirements. Recommended for new designs requiring automotive-grade specifications.

RC1206FR-0718R2L (YAGEO): This substitute maintains Active product status with complete parameter equivalence. Moisture-resistant construction aligns with the original part's environmental protection features. Seated height of 0.026" (0.65mm) matches the original specification within manufacturing tolerances. Inventory of 5100 pieces is available. Suitable for applications where automotive qualification is not required.

ERJ-8ENF18R2V (Panasonic Electronic Components): This part meets all electrical and mechanical specifications with Automotive AEC-Q200 qualification. However, product status is listed as "Not For New Designs," indicating this part is in end-of-life phase. Seated height of 0.028" (0.70mm) remains within acceptable assembly tolerances. Inventory of 59595 pieces is available. Use only for legacy system maintenance or existing design continuity where new design qualification is not applicable.

Frequently Asked Questions (FAQ)

Q: Can CRCW120618R2FKEA directly replace RCS3216F18R2CS without PCB layout changes?

A: Yes. Both parts use identical 1206 (3216 Metric) package format with compatible footprints. Seated height variations (0.024" vs 0.026") fall within standard PCB assembly tolerances and do not require layout modification.

Q: What is the significance of the "Not For New Designs" status on ERJ-8ENF18R2V?

A: This designation indicates the part is in end-of-life phase. While electrically and mechanically equivalent, Panasonic has discontinued new production. Use this part only for maintenance of existing designs or legacy system support where design re-qualification is not feasible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (CRCW120618R2FKEA, ERJ-8ENF18R2V, and RC1206FR-0718R2L) maintain ROHS3 compliance matching the original RCS3216F18R2CS specification.

Q: Do the substitute parts maintain the same temperature performance?

A: Yes. All substitute parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, providing identical thermal performance to the original part.

Q: Which substitute offers the best long-term availability?

A: CRCW120618R2FKEA (Vishay Dale) maintains Active product status with 39624 pieces in inventory. RC1206FR-0718R2L (YAGEO) also maintains Active status with 5100 pieces available. ERJ-8ENF18R2V is in end-of-life phase and should not be selected for new designs.

Q: Is Automotive AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is required only for automotive applications. CRCW120618R2FKEA and ERJ-8ENF18R2V include this certification. RC1206FR-0718R2L does not carry automotive qualification but meets all electrical specifications for general industrial and consumer applications.
