Substitute Part Grouping Explanation

Substitute parts for RC3216F1822CS are qualified based on the following critical parameters that determine functional equivalence:

Electrical Parameters (Must Match Exactly):

Resistance value: 18.2 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

Package type: 1206 (3216 Metric)
Number of terminations: 2
Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

RoHS3 Compliant
REACH Unaffected
MSL 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product status or additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution eligibility when core electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-1822ELF (Bourns Inc.), RC1206FR-0718K2L (YAGEO), RMCF1206FT18K2 (Stackpole Electronics Inc), CRCW120618K2FKEA (Vishay Dale), and KTR18EZPF1822 (Rohm Semiconductor) are all qualified direct substitutes with Active product status. These components maintain identical electrical specifications and 1206 package compliance. Selection among these options may be based on availability, packaging format (Tape & Reel or Cut Tape), or supply chain requirements.

Secondary Substitute (Legacy Status):

ERJ-8ENF1822V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" product status. This component is suitable for replacement in existing production runs or field service applications where the original RC3216F1822CS is unavailable, but should not be selected for new circuit designs.

Automotive Applications:

RMCF1206FT18K2, CRCW120618K2FKEA, and KTR18EZPF1822 include AEC-Q200 automotive qualification. These components are appropriate for automotive or high-reliability applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1822ELF directly replace RC3216F1822CS without circuit redesign?

A: Yes. Both components share identical resistance (18.2 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: Active status indicates the manufacturer continues production and recommends the component for new circuit designs. "Not For New Designs" indicates the manufacturer may discontinue production or has released a newer alternative. ERJ-8ENF1822V carries this status but remains functionally equivalent for replacement applications.

Q: Are there dimensional differences between substitute parts?

A: Minor variations exist within 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility or circuit function.

Q: Which substitute should be selected for automotive applications?

A: RMCF1206FT18K2 (Stackpole Electronics Inc), CRCW120618K2FKEA (Vishay Dale), or KTR18EZPF1822 (Rohm Semiconductor) are recommended for automotive applications, as all three carry AEC-Q200 automotive qualification. The original RC3216F1822CS does not specify AEC-Q200 certification.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. All substitute parts maintain identical electrical specifications regardless of packaging configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts and the original RC3216F1822CS are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
