Substitute Part Grouping Explanation

Substitute parts for the Bourns 4624-RC are identified based on the following critical electrical and mechanical parameters:

• Inductance Value: 15 µH (exact match required)
• Current Rating: 1 A (minimum requirement)
• DC Resistance: 170 mOhm maximum (performance threshold)
• Mounting Type: Through Hole (form factor compatibility)
• Package / Case: Axial (physical compatibility)
• Physical Dimensions: 0.290" Dia x 0.875" L (board layout compatibility)
• Shielding Configuration: Unshielded (electromagnetic environment match)

The Hammond Manufacturing 1532B meets all critical substitution criteria and maintains functional equivalence with the obsolete Bourns component.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1532B is a direct functional substitute for the obsolete Bourns 4624-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

The Hammond 1532B maintains active product status, ensuring ongoing availability and supply chain stability. The component shares identical electrical specifications for inductance value, current rating, and DC resistance, with matching physical dimensions and mounting configuration.

The inductance tolerance specification for the Hammond 1532B is ±10% compared to ±5% for the Bourns component. This tolerance difference must be evaluated against application requirements where inductance precision is critical to circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1532B be used as a direct replacement for the Bourns 4624-RC?

A: Yes. Both components share identical inductance values (15 µH), current ratings (1 A), DC resistance specifications (170 mOhm max), physical dimensions (0.290" Dia x 0.875" L), and mounting configurations (through-hole axial). Electrical performance characteristics including Q factor and self-resonant frequency are equivalent.

Q: What is the difference in inductance tolerance between these parts?

A: The Bourns 4624-RC specifies ±5% inductance tolerance, while the Hammond 1532B specifies ±10%. Applications requiring tighter inductance tolerance control must account for this specification difference during circuit design validation.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the Bourns 4624-RC and Hammond 1532B are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the physical compatibility between these components?

A: Both components are identical in physical dimensions (0.290" Dia x 0.875" L / 7.37mm x 22.22mm), mounting type (through-hole), and package configuration (axial). No PCB layout modifications are required for substitution.

Q: Why is the Bourns 4624-RC listed as obsolete?

A: The Bourns 4624-RC has reached end-of-life status. The Hammond 1532B maintains active product status and provides equivalent electrical and mechanical functionality for ongoing design requirements.
