Engineering Selection Recommendations

For Standard Applications (Non-Automotive): CR1206-FX-1820ELF (Bourns Inc.) or RC1206FR-07182RL (YAGEO) are direct substitutes meeting all electrical and mechanical requirements with Active product status and ROHS3 compliance. Both parts maintain identical electrical specifications and operating temperature range.

For Automotive Applications (AEC-Q200 Required): AC1206FR-07182RL (YAGEO) or CRCW1206182RFKEA (Vishay Dale) provide automotive-grade equivalents with AEC-Q200 certification. Both maintain Active product status and ROHS3 compliance. These parts are suitable for automotive circuit applications requiring enhanced reliability qualification.

For Legacy System Maintenance: CRCW1206182RFKTA (Vishay Dale) provides functional equivalence with AEC-Q200 certification but carries RoHS non-compliant status. This part is suitable only for replacement in existing systems where RoHS compliance is not mandated.

Obsolescence Consideration: ERJ-8ENF1820V (Panasonic Electronic Components) is marked "Not For New Designs" and should not be selected for new product development. This part is available for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1820ELF replace RC3216F1820CS in any application?

A: CR1206-FX-1820ELF is a direct electrical and mechanical equivalent. Both parts share identical resistance (182 Ω), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Substitution is valid for applications not requiring automotive certification.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (CR1206-FX-1820ELF, RC1206FR-07182RL) meet all core electrical and mechanical specifications without additional certifications. Upgrade substitutes (AC1206FR-07182RL, CRCW1206182RFKEA, CRCW1206182RFKTA) include AEC-Q200 automotive qualification, providing enhanced reliability for automotive applications.

Q: Is CRCW1206182RFKTA suitable for new designs?

A: CRCW1206182RFKTA is functionally equivalent but carries RoHS non-compliant status. This part is suitable for replacement in existing systems only. For new designs, select ROHS3-compliant alternatives such as AC1206FR-07182RL or CRCW1206182RFKEA.

Q: Why is ERJ-8ENF1820V marked "Not For New Designs"?

A: ERJ-8ENF1820V is classified as "Not For New Designs" by the manufacturer, indicating the part is in end-of-life status. While electrically equivalent, this part should be used only for legacy system maintenance and repair. New product development should utilize Active-status alternatives.

Q: Are all substitute parts available in Tape & Reel packaging?

A: CR1206-FX-1820ELF, RC1206FR-07182RL, AC1206FR-07182RL, CRCW1206182RFKEA, CRCW1206182RFKTA, and ERJ-8ENF1820V are all supplied in Tape & Reel (TR) packaging. The original RC3216F1820CS is supplied in standard packaging. Tape & Reel format is standard for high-volume manufacturing applications.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts share this MSL rating, ensuring equivalent moisture sensitivity characteristics.

Q: Can these parts be used interchangeably on the same PCB?

A: All substitute parts are mechanically compatible with 1206 footprints. Physical dimensions vary slightly (length 0.122" to 0.126", height 0.024" to 0.030"), but all fall within standard 1206 package tolerances and are compatible with standard 1206 PCB land patterns.
