Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5519-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 68 µH
• Current rating: 10 A minimum
• DC resistance: 23 mOhm maximum
• Mounting type: Through hole
• Package configuration: Radial, horizontal cylinder
• Physical dimensions: 0.940" Dia x 1.380" L (23.88mm x 35.05mm)
• Shielding classification: Unshielded

The Hammond Manufacturing 1538M19 meets all these criteria and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M19 is the direct equivalent for the obsolete Bourns 5519-RC. Both components share identical electrical specifications (68 µH inductance, 10 A current rating, 23 mOhm maximum DC resistance) and mechanical form factors. The Hammond part offers superior tolerance performance (±10% versus ±20%), providing tighter inductance control in circuit applications.

Selection of the Hammond 1538M19 is supported by active product status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and equivalent regulatory certifications (REACH Unaffected, EAR99 ECCN classification), confirming suitability for equivalent applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M19 directly replace the Bourns 5519-RC without PCB modification?

A: Yes. Both components share identical physical dimensions (0.940" Dia x 1.380" L), radial through-hole mounting configuration, and electrical specifications. No PCB layout changes are required.

Q: What is the significance of the tolerance difference between these parts?

A: The Bourns 5519-RC specifies ±20% inductance tolerance, while the Hammond 1538M19 specifies ±10%. The Hammond part provides tighter inductance control, which may improve circuit performance in applications sensitive to inductance variation. Both tolerances are acceptable for standard filtering and energy storage applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS codes. They are equivalent from a regulatory and environmental compliance perspective.

Q: Why is the Bourns 5519-RC classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The Hammond 1538M19 maintains active product status, ensuring continued availability and manufacturing support.

Q: Are the core materials equivalent between these inductors?

A: The Bourns 5519-RC specifies ferrite core material. The Hammond 1538M19 core material is not specified in the provided data. Both components deliver identical electrical performance at the specified test frequency (1 kHz) and operating conditions.
