Substitute Part Grouping Explanation

Substitution of the 5619-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 50 µH
• Inductance tolerance: ±10%
• Current rating: 14 A minimum
• DC resistance: 12 mOhm maximum
• Core material and shielding: Ferrite, unshielded
• Mounting configuration: Through hole, radial vertical cylinder
• Physical dimensions: 1.500" diameter, 1.110" maximum seated height
• Inductance measurement frequency: 1 kHz

The Hammond Manufacturing 1539M19 meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent for the obsolete 5619-RC.

Parameter Comparison

Engineering Selection Recommendations

All electrical parameters, mechanical dimensions, and mounting configurations are identical between the two parts. Direct substitution is supported without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M19 be used as a direct replacement for the Bourns 5619-RC?

A: Yes. Both components share identical inductance (50 µH), tolerance (±10%), current rating (14 A), DC resistance (12 mOhm max), core type (ferrite, unshielded), and physical dimensions (1.500" diameter, 1.110" max height). Through-hole radial mounting is identical on both parts.

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

A: No. Both the 5619-RC and 1539M19 are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.

Q: What is the primary reason for substitution?

A: The Bourns 5619-RC is obsolete. The Hammond 1539M19 maintains active product status with available inventory, ensuring continued supply for new production and field service applications.

Q: Will the 1539M19 fit the existing PCB layout designed for the 5619-RC?

A: Yes. Identical package configuration (radial, vertical cylinder) and dimensions (1.500" diameter, 1.110" seated height) ensure direct board-level compatibility without layout modification.

Q: Are the inductance measurement conditions the same?

A: Yes. Both components are specified at 1 kHz inductance test frequency, ensuring measurement consistency and performance equivalence.
