Bourns 4622-RC 10µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 4622-RC is a 10µH unshielded drum core wirewound inductor rated for 1.5A continuous current with 110mOhm maximum DC resistance. Designed for through-hole axial mounting, this component operates across the -55°C to 105°C temperature range and is compliant with ROHS3 and REACH standards.

The 4622-RC carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this inductance value and current rating.

Engineering Selection Recommendations

The Hammond Manufacturing 1532A provides a direct substitute for the obsolete Bourns 4622-RC. Both components share identical electrical specifications for inductance, current rating, and DC resistance, with matching physical dimensions and mounting configuration.

The Hammond 1532A carries active product status, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current applications.

The primary difference is inductance tolerance: the 4622-RC specifies ±5% while the 1532A specifies ±10%. Applications requiring tighter tolerance control should evaluate this specification against circuit performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1532A replace the Bourns 4622-RC in existing designs?

A: Yes. Both inductors share identical inductance values (10µH), current ratings (1.5A), DC resistance (110mOhm max), physical dimensions (0.290" Dia x 0.875" L), and mounting configuration (through-hole axial). The components are electrically and mechanically compatible.

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

A: The Bourns 4622-RC specifies ±5% tolerance while the Hammond 1532A specifies ±10% tolerance. Applications with strict inductance requirements should evaluate whether the wider tolerance of the 1532A affects circuit performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Bourns 4622-RC and Hammond 1532A are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the Bourns 4622-RC listed as obsolete?

A: The 4622-RC has been discontinued by Bourns Inc. The Hammond 1532A, with active product status, provides continued availability for this inductance and current rating specification.

Q: Do these inductors have identical physical footprints?

A: Yes. Both components measure 0.290" diameter by 0.875" length (7.37mm x 22.22mm) in axial configuration, enabling direct board-level substitution without layout modifications.
