Frequently Asked Questions (FAQ)

Q: Can CM6296R-304 replace CM6296-304 in existing designs?

A: Yes. The CM6296R-304 provides identical electrical performance (300 µH @ 1 kHz, 7.5A, 20 mOhm DCR) and mechanical compatibility (same footprint, dimensions, and package configuration). The primary difference is RoHS3 compliance certification on the CM6296R-304 variant.

Q: What is the difference between CM6296-304 and CM6296R-304?

A: Both parts are manufactured by API Delevan Inc. and share identical inductance, current rating, DC resistance, operating temperature range, and physical dimensions. The CM6296R-304 carries ROHS3 compliance certification, while the CM6296-304 is RoHS non-compliant. All other specifications, including REACH status and ECCN classification, are identical.

Q: Are the physical footprints identical?

A: Yes. Both parts feature identical dimensions of 1.058" L x 1.058" W (26.87mm x 26.87mm) with a maximum height of 0.423" (10.74mm). Both use Horizontal, 4 PC Pad package configuration, ensuring direct PCB compatibility.

Q: What is the moisture sensitivity level for these parts?

A: Both CM6296-304 and CM6296R-304 have a Moisture Sensitivity Level (MSL) rating of 5A (24 Hours), indicating identical moisture handling requirements during storage and assembly.

Q: Which part should be selected for new product designs?

A: For new designs, CM6296R-304 is recommended due to ROHS3 compliance certification, which aligns with current regulatory standards and environmental requirements. Both parts are in active production status with adequate inventory availability.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range of -55°C ~ 125°C and maintain the same electrical specifications: 300 µH @ 1 kHz inductance, 7.5A maximum current rating, and 20 mOhm maximum DC resistance.
