Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5615-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 250 µH
• Inductance tolerance: ±10%
• Current rating: 4.6 A minimum
• DC resistance: 83 mOhm maximum
• Core type: Ferrite, unshielded drum core
• Mounting configuration: Through-hole, radial vertical cylinder
• Physical dimensions: 1.220" diameter and 1.110" height (within manufacturing tolerances)
• Regulatory compliance: ROHS3 compliant

The Hammond Manufacturing 1539M15 meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1539M15 is the qualified substitute for the Bourns 5615-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Hammond part maintains active product status, ensuring ongoing availability and supply chain continuity. Electrical specifications, physical dimensions, and thermal operating range are equivalent between the two components. The negligible dimensional variance (0.01 mm diameter difference) is within standard manufacturing tolerances and does not affect mechanical fit or electrical performance in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M15 be used as a direct replacement for the Bourns 5615-RC?

A: Yes. Both components share identical electrical specifications (250 µH, 4.6 A, 83 mOhm DCR), core material (ferrite), shielding configuration (unshielded), and physical package (radial vertical cylinder through-hole). Dimensional compatibility is confirmed within manufacturing tolerances.

Q: What is the primary reason for substitution?

A: The Bourns 5615-RC is classified as obsolete. The Hammond 1539M15 is an active product with equivalent specifications, providing procurement continuity and long-term availability.

Q: Are there any compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory status is identical.

Q: Does the Hammond part fit the same PCB footprint?

A: Yes. Both components use identical through-hole radial vertical cylinder packaging with equivalent dimensions (1.220" diameter, 1.110" height). PCB layout compatibility is maintained.

Q: What parameters must remain constant for substitution to be valid?

A: Inductance (250 µH), tolerance (±10%), current rating (4.6 A), DC resistance (83 mOhm max), core material (ferrite), shielding (unshielded), and mounting type (through-hole radial vertical cylinder) must all match. Any deviation from these specifications invalidates the substitution.
