5631-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5631-RC is a 5 mH unshielded drum core wirewound inductor rated for 2.2 A continuous current with a maximum DC resistance of 714 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is mounted in a radial, vertical cylinder configuration with a 1.500" diameter and 1.110" seated height.

The 5631-RC is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this inductance value and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5631-RC is determined by strict equivalence across the following parameters:

• Inductance value: 5 mH
• Inductance tolerance: ±10%
• Current rating: 2.2 A minimum
• DC resistance: 714 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Test frequency: 1 kHz

The Hammond Manufacturing 1539M31 meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1539M31 is a qualified substitute for the obsolete Bourns 5631-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 1539M31 is classified as active product status, ensuring ongoing availability and supply chain support.

The primary dimensional difference is seated height: the 5631-RC measures 1.110" while the 1539M31 measures 1.500". This difference must be evaluated against available PCB clearance and mechanical constraints in the target application. All electrical parameters—inductance, current rating, and DC resistance—are identical between the two components.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M31 replace the Bourns 5631-RC in all applications?

A: The 1539M31 is electrically equivalent across all specified parameters. However, the increased seated height (1.500" versus 1.110") requires verification of available vertical clearance on the PCB and within the enclosure.

Q: Are there any compliance differences between these parts?

A: Both components carry identical regulatory certifications: ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification.

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

A: The ±10% tolerance defines the acceptable range of inductance values at the 1 kHz test frequency. Both the 5631-RC and 1539M31 share this tolerance specification, ensuring equivalent circuit performance.

Q: Does the packaging difference affect electrical performance?

A: Packaging format (bulk for 1539M31 versus standard for 5631-RC) does not affect electrical characteristics. The difference is administrative and relates to supplier delivery format only.

Q: What is the DC resistance specification used for?

A: The 714 mOhm maximum DC resistance specification defines the resistive losses in the inductor winding. This parameter is critical for thermal calculations and power dissipation analysis in the application circuit.
