Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production):

CR1206-FX-3091ELF (Bourns Inc.) and CRCW12063K09FKEA (Vishay Dale) are recommended as primary substitutes. Both parts are in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Bourns CR1206-FX-3091ELF offers 25,813 pieces in stock inventory. Vishay Dale CRCW12063K09FKEA includes automotive AEC-Q200 qualification with 28,443 pieces available, suitable for applications requiring automotive-grade reliability.

Secondary Selection (Active Production):

RC1206FR-073K09L (YAGEO) is an active production alternative with 4,400 pieces in stock. This part meets all electrical and mechanical specifications with RoHS3 compliance and MSL 1 rating.

Legacy Consideration:

ERJ-8ENF3091V (Panasonic Electronic Components) carries a "Not For New Designs" status despite 120,405 pieces in inventory. This part meets all electrical and mechanical parameters but should be used only for replacement or maintenance of existing designs. New circuit designs should utilize active production alternatives.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-3091ELF directly replace RCS3216F3091CS without PCB modification?

A: Yes. Both parts share identical electrical specifications (3.09 kOhms ±1%, 0.25W, ±100ppm/°C) and 1206 package footprint. Maximum seated heights differ by 0.004" (0.09mm), which is within standard PCB assembly tolerances and does not require layout changes.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: CR1206-FX-3091ELF features moisture-resistant thick film construction. CRCW12063K09FKEA and ERJ-8ENF3091V include automotive AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive applications. Both meet MSL 1 (Unlimited) moisture sensitivity requirements.

Q: Why is ERJ-8ENF3091V marked "Not For New Designs"?

A: This designation indicates the part is in legacy status. While electrically and mechanically equivalent, Panasonic has discontinued active development. New circuit designs should specify CR1206-FX-3091ELF, CRCW12063K09FKEA, or RC1206FR-073K09L to ensure long-term supply chain continuity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, meeting EU Directive 2011/65/EU requirements for restricted substances.

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

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. These parts can be stored indefinitely at standard conditions without degradation, simplifying inventory management and reducing component preparation time before assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting identical thermal performance specifications for applications within this range.
