Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1267AY-2R2N=P3 is determined by the following critical parameters:

• Inductance value of 2.2 µH within the specified tolerance range
• Current rating capability of 7.2 A minimum (96.8% of primary part rating)
• DC resistance not exceeding 13.2 mOhm maximum
• Ferrite core material with shielding
• Surface mount configuration
• 100 kHz test frequency alignment
• RoHS3 compliance certification

The BWVS008080402R2M00 from Pulse Electronics meets these substitution criteria with equivalent inductance, comparable current handling, and superior DC resistance performance.

Parameter Comparison

Engineering Selection Recommendations

The BWVS008080402R2M00 is a qualified substitute for the 1267AY-2R2N=P3 based on the following engineering criteria:

Both components maintain Active product status and full RoHS3 compliance. The substitute part demonstrates superior DC resistance performance at 11.5 mOhm compared to the 13.2 mOhm maximum of the primary part, resulting in lower power dissipation. The current rating differential of 0.2 A (2.7% reduction) remains within acceptable margins for most applications operating below the 7.4 A maximum specification. Inductance tolerance of ±20% on the substitute part is tighter than the ±30% specification of the primary part, providing improved consistency. Both components utilize identical ferrite core material, shielding configuration, and surface mount packaging. The substitute part provides documented operating temperature range (-55°C ~ 125°C) and saturation current specification (9.2 A), offering additional design margin information not specified for the primary part.

Frequently Asked Questions (FAQ)

Q: Can the BWVS008080402R2M00 be used as a direct replacement for the 1267AY-2R2N=P3?

A: Yes, the BWVS008080402R2M00 qualifies as a direct substitute. Both parts share identical inductance values, ferrite core material, shielding, surface mount configuration, and RoHS3 compliance. The substitute part offers improved DC resistance and tighter inductance tolerance.

Q: What is the significance of the 0.2 A current rating difference?

A: The BWVS008080402R2M00 is rated for 7.2 A versus 7.4 A for the primary part. This 2.7% reduction is acceptable for applications not requiring the full 7.4 A specification. Applications operating at or near 7.4 A should retain the primary part.

Q: Are the physical dimensions compatible?

A: Both parts are surface mount components with similar footprints. The primary part measures 0.327" L x 0.327" W (8.30mm x 8.30mm) with 0.157" height, while the substitute measures 0.315" L x 0.315" W (8.00mm x 8.00mm) with 0.165" height. These minor dimensional variations are within standard PCB layout tolerances for surface mount inductors.

Q: What packaging formats are available?

A: The primary part is supplied in Cut Tape (CT) & Digi-Reel format. The substitute part is supplied in Tape & Reel (TR) format. Both formats are standard for surface mount component distribution.

Q: How do the inductance tolerances affect circuit performance?

A: The primary part specifies ±30% tolerance, while the substitute specifies ±20%. The tighter tolerance of the substitute part provides improved consistency in inductance values across production batches, which may benefit applications with tight frequency or impedance requirements.

Q: Is the operating temperature range a consideration for substitution?

A: The substitute part specifies an operating temperature range of -55°C ~ 125°C. The primary part does not provide a specified operating temperature range. If your application requires operation outside this range, the primary part specifications should be confirmed with the manufacturer.
