Bourns 5622-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5622-RC is a 500 µH unshielded drum core wirewound inductor rated for 5 A continuous current with a maximum DC resistance of 90 mOhm. This through-hole radial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5622-RC carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for legacy system maintenance and new production runs requiring compatible inductance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M22 replace the Bourns 5622-RC in existing designs?

A: Yes. The 1539M22 matches all critical electrical parameters (500 µH inductance, 5 A current rating, 90 mOhm maximum DC resistance) and physical dimensions (1.500" diameter, 1.110" height) of the 5622-RC. Through-hole radial mounting is identical, enabling direct substitution.

Q: Are there differences in operating temperature ranges between these parts?

A: The Bourns 5622-RC specifies -55°C to 105°C operation. The Hammond 1539M22 operating temperature range is not provided in the available specifications. Confirm temperature requirements with Hammond Manufacturing if operation below 0°C or above 85°C is required.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 5622-RC and 1539M22 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the significance of the ±10% inductance tolerance?

A: The ±10% tolerance indicates that actual inductance values may range from 450 µH to 550 µH. Both parts share this tolerance specification, ensuring equivalent circuit behavior across the tolerance band.

Q: Why is the Bourns 5622-RC listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Hammond 1539M22 maintains active status, providing a reliable long-term supply source for equivalent inductance requirements.
