Parameter Comparison

Engineering Selection Recommendations

The BWVS00808040470M00 is a qualified substitute for the 1267AY-470M=P3 based on the following factors:

Electrical Compatibility: Both components maintain 47 µH inductance at ±20% tolerance with ferrite core construction. The substitute provides 1.75 A current rating, exceeding the 1.6 A requirement. DC resistance of 160 mOhm is within acceptable range relative to the 168 mOhm maximum specification.

Compliance Alignment: Both parts are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring equivalent environmental and moisture handling requirements.

Product Status: Both components are Active status, confirming ongoing manufacturer support and availability.

Packaging Consideration: The substitute is supplied in Tape & Reel format, whereas the main part uses nonstandard packaging. Verify tape & reel compatibility with assembly equipment before implementation.

Frequently Asked Questions (FAQ)

Q: Can the BWVS00808040470M00 directly replace the 1267AY-470M=P3 in existing designs?

A: Yes, provided that the Tape & Reel packaging format is compatible with your assembly process. Electrical parameters are equivalent within specification tolerances.

Q: What is the significance of the 1.75 A current rating on the substitute versus 1.6 A on the main part?

A: The higher current rating on the substitute provides additional design margin. If your circuit operates at or near 1.6 A, the substitute offers improved thermal headroom without requiring circuit redesign.

Q: Are there differences in physical dimensions between these parts?

A: Yes. The main part measures 0.327" L x 0.327" W x 0.157" H (8.30mm x 8.30mm x 4.00mm). The substitute measures 0.315" L x 0.315" W x 0.165" H (8.00mm x 8.00mm x 4.20mm). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. MSL rating is identical at level 1 (Unlimited).

Q: What is the inductance tolerance range for these parts?

A: Both parts are specified at ±20% tolerance. At 47 µH nominal, this represents a range of 37.6 µH to 56.4 µH. Verify that your circuit design accommodates this tolerance band.
