The CRM1206-FX-R047ELF is a direct functional equivalent to the obsolete CRL1206-FV-R047ELF. Both components satisfy identical electrical specifications for resistance value, tolerance, and power dissipation. The substitute part is manufactured by the same supplier (Bourns Inc.) and maintains full RoHS3 and REACH compliance.

The CRM1206-FX-R047ELF offers an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and improved temperature coefficient performance (±100ppm/°C versus ±400ppm/°C). These enhancements provide superior performance margins without compromising compatibility.

The substitute part is currently in active production status with confirmed inventory availability, ensuring reliable procurement for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the CRM1206-FX-R047ELF be used as a direct replacement for the CRL1206-FV-R047ELF?

A: Yes. Both parts share identical electrical specifications (47 mOhms, ±1% tolerance, 0.5W power rating) and mechanical package (1206/3216 Metric). The substitute maintains all required compliance certifications.

Q: What are the physical dimension differences between these parts?

A: The CRL1206-FV-R047ELF measures 0.126" L × 0.063" W × 0.028" H (3.20mm × 1.60mm × 0.70mm). The CRM1206-FX-R047ELF measures 0.122" L × 0.063" W × 0.026" H (3.10mm × 1.60mm × 0.65mm). Both dimensions fall within the 1206 package specification and are compatible with standard PCB footprints.

Q: Are there temperature performance differences?

A: The CRM1206-FX-R047ELF operates to 155°C maximum versus 125°C for the CRL1206-FV-R047ELF. The substitute also features a lower temperature coefficient (±100ppm/°C versus ±400ppm/°C), providing improved stability across temperature variations.

Q: What packaging formats are available for the substitute part?

A: The CRM1206-FX-R047ELF is supplied in Tape & Reel (TR) format. Confirm packaging requirements for your procurement process.

Q: Do both parts maintain the same compliance status?

A: Yes. Both the CRL1206-FV-R047ELF and CRM1206-FX-R047ELF are RoHS3 compliant and REACH unaffected, with identical Moisture Sensitivity Level 1 (unlimited) ratings.

Q: Why is the main part listed as obsolete?

A: The CRL1206-FV-R047ELF has been discontinued by the manufacturer. The CRM1206-FX-R047ELF represents the active production equivalent for this resistance value and package type.
