5512-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5512-RC is a 68 µH unshielded drum core wirewound inductor rated for 7.3 A with a maximum DC resistance of 34 mOhm. This through-hole component is designed for radial, horizontal cylinder mounting in applications requiring fixed inductance values with moderate current handling capability. The 5512-RC is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5512-RC is determined by the following critical parameters:

• Inductance Value: 68 µH (exact match required)
• Current Rating: 7.3 A (minimum requirement)
• DC Resistance: 34 mOhm maximum (electrical performance constraint)
• Shielding Configuration: Unshielded (electromagnetic environment compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial, Horizontal Cylinder (physical footprint and orientation)
• Size / Dimension: 0.880" Dia x 1.120" L (22.35mm x 28.45mm) (board layout constraint)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The Hammond Manufacturing 1538M12 meets all substitution criteria across these parameters, establishing it as a direct equivalent for the obsolete 5512-RC.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M12 is the direct equivalent substitute for the obsolete Bourns 5512-RC. Both components satisfy identical electrical specifications (68 µH inductance, 7.3 A current rating, 34 mOhm maximum DC resistance) and physical form factors (0.880" Dia x 1.120" L radial horizontal cylinder). The 1538M12 maintains full compliance with ROHS3 and REACH standards, ensuring regulatory continuity in applications previously using the 5512-RC.

The 1538M12 offers a tighter inductance tolerance (±10% versus ±20%), which may provide improved circuit performance in applications sensitive to inductance variation. Both components are rated for the same operating temperature range and test frequency, ensuring functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M12 be used as a direct replacement for the Bourns 5512-RC without PCB modifications?

A: Yes. Both components share identical physical dimensions (0.880" Dia x 1.120" L), mounting type (through-hole radial), and package configuration (horizontal cylinder). No PCB layout changes are required.

Q: Are there electrical performance differences between the 5512-RC and 1538M12?

A: Both components deliver 68 µH inductance at 1 kHz with 7.3 A current rating and 34 mOhm maximum DC resistance. The 1538M12 features a tighter inductance tolerance (±10% versus ±20%), which may reduce circuit performance variation in tolerance-sensitive applications.

Q: What is the compliance status of the 1538M12 substitute?

A: The 1538M12 is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 5512-RC component.

Q: Is the 1538M12 currently available for procurement?

A: Yes. The 1538M12 is classified as active product status with documented inventory availability, unlike the obsolete 5512-RC.

Q: Are there any shielding or electromagnetic compatibility differences?

A: Both the 5512-RC and 1538M12 are unshielded wirewound inductors. Electromagnetic environment compatibility remains unchanged when substituting between these components.
