Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IHA202BA are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

• Inductance Value: Must be exactly 50 µH
• Current Rating: Must be rated for 3.1 A minimum
• DC Resistance: Must not exceed 85 mOhm
• Core Configuration: Must be unshielded drum core construction
• Winding Type: Must be wirewound
• Package Format: Must be axial through-hole
• Manufacturer Series: Must belong to the IHA series from Vishay Dale

Only parts meeting all these parameters are considered true electrical and mechanical equivalents suitable for direct substitution without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The IHA202EB is a direct parametric equivalent to the IHA202BA. Both components share identical electrical specifications (50 µH inductance, 3.1 A current rating, 85 mOhm maximum DC resistance) and mechanical construction (unshielded drum core, wirewound, axial through-hole). Selection between these parts should be based on inventory availability and procurement lead times. The IHA202EB currently has higher stock availability (1597 Pcs) compared to the IHA202BA (731 Pcs), making it a viable alternative for immediate sourcing needs.

Frequently Asked Questions (FAQ)

Q: Can the IHA202EB be used as a direct replacement for the IHA202BA?

A: Yes. The IHA202EB meets all electrical and mechanical specifications of the IHA202BA, including inductance value, current rating, DC resistance, core type, winding configuration, and package format. No circuit modifications are required.

Q: What parameters must match for a valid substitution?

A: All of the following must be identical: inductance (50 µH), current rating (3.1 A), maximum DC resistance (85 mOhm), core type (unshielded drum core), winding style (wirewound), and package type (axial through-hole).

Q: Are there any packaging or lead configuration differences between these parts?

A: Both the IHA202BA and IHA202EB use axial through-hole packaging with identical lead configurations, ensuring mechanical compatibility in PCB layouts.

Q: What is the difference between the IHA202BA and IHA202EB designations?

A: The different suffix letters (BA vs. EB) indicate different manufacturing batches or revisions within the IHA series, but both parts maintain identical electrical and mechanical specifications.

Q: Can I mix IHA202BA and IHA202EB components in the same production run?

A: Yes. Since both parts are parametric equivalents with identical specifications, they can be used interchangeably in the same circuit design and production environment.
