Bourns 5508-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5508-RC is a 5 µH unshielded drum core wirewound inductor rated for 14 A continuous current with a maximum DC resistance of 9 mOhm. This through-hole radial component operates across the temperature range of -55°C to 105°C and is specified at 1 kHz inductance frequency. The 5508-RC carries an obsolete product status, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 5508-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 5 µH
• Current rating: 14 A minimum
• DC resistance: 9 mOhm maximum
• Shielding configuration: Unshielded
• Mounting technology: Through hole
• Physical form factor: Radial, horizontal cylinder with matching dimensions (0.640" Dia x 0.880" L)
• Inductance measurement frequency: 1 kHz
• Regulatory compliance: ROHS3 compliant

The Hammond Manufacturing 1538M08 meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M08 is the qualified substitute for the obsolete Bourns 5508-RC. Both components maintain identical electrical specifications for inductance, current rating, and DC resistance. The 1538M08 offers improved inductance tolerance (±10% versus ±20%), providing tighter performance margins in applications requiring precision inductance values.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The 1538M08 maintains active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete 5508-RC.

Physical form factor and mounting characteristics are identical, permitting direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M08 replace the Bourns 5508-RC in existing designs?

A: Yes. The 1538M08 matches all critical electrical and mechanical parameters: 5 µH inductance, 14 A current rating, 9 mOhm maximum DC resistance, unshielded configuration, through-hole mounting, and identical physical dimensions. PCB layout compatibility is maintained.

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

A: The 5508-RC specifies ±20% tolerance, while the 1538M08 specifies ±10% tolerance. The tighter tolerance of the 1538M08 provides improved inductance accuracy for applications sensitive to component variation.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 5508-RC and 1538M08 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the Bourns 5508-RC listed as obsolete?

A: The 5508-RC carries obsolete product status. The Hammond 1538M08 is an active product with current manufacturing and inventory support, making it the recommended selection for new designs and ongoing procurement.

Q: Are there any differences in core material between these inductors?

A: The 5508-RC specifies ferrite drum core material. The 1538M08 core material is not specified in the provided data. Both components deliver equivalent electrical performance at the specified inductance value and frequency.
