Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1267AY-100M=P3 are qualified based on the following criteria:

Inductance value must be 10 µH with ±20% tolerance to maintain circuit performance. Shielding type must remain shielded to preserve electromagnetic isolation properties. Core material must be ferrite to ensure equivalent magnetic characteristics. Current rating must meet or exceed 3.3 A to support the application load. DC resistance must not exceed 39.6mOhm to maintain acceptable power dissipation. Mounting type must be surface mount to ensure mechanical compatibility. All parts must be tested at 100 kHz to ensure measurement consistency.

Parameter Comparison

Engineering Selection Recommendations

The BWVS00808040100M00 from Pulse Electronics qualifies as a direct substitute for the 1267AY-100M=P3. Both components maintain identical inductance values and tolerances at the 100 kHz test frequency. The substitute part provides improved current handling capability at 3.8 A versus 3.3 A, with lower DC resistance at 38 mOhm compared to 39.6 mOhm maximum. Both parts are RoHS3 compliant with MSL rating of 1 and REACH unaffected status, meeting equivalent regulatory requirements. The substitute part includes specified operating temperature range of -55°C to 125°C, providing additional environmental specification clarity. Packaging differs between cut tape and tape & reel formats; application requirements determine the appropriate packaging selection.

Frequently Asked Questions (FAQ)

Q: Can BWVS00808040100M00 replace 1267AY-100M=P3 in all applications?

A: Yes, provided the application does not require the specific cut tape packaging format of the original part. The electrical and mechanical parameters are compatible within the specified tolerances.

Q: What is the significance of the current rating difference?

A: The substitute part's higher current rating of 3.8 A versus 3.3 A indicates improved thermal performance and current handling capacity. This provides additional design margin for applications operating near the original part's current limit.

Q: Are there packaging considerations for substitution?

A: The main part is supplied in cut tape format, while the substitute is supplied in tape & reel format. Verify that your assembly process and inventory management systems support the substitute packaging configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level), ensuring equivalent regulatory compliance.

Q: What is the impact of the lower DC resistance in the substitute part?

A: Lower DC resistance reduces power dissipation and heat generation during operation, which is beneficial for thermal management and efficiency in the application circuit.
