Bourns 5614-RC 100µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5614-RC is a 100µH unshielded drum core wirewound inductor rated for 7A continuous current with 34mOhm maximum DC resistance. This through-hole radial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5614-RC carries obsolete product status. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for legacy systems or new designs requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the 5614-RC are qualified based on the following critical parameters:

Inductance Value: 100 µH (exact match required)
DC Resistance: 34 mOhm Max (exact match required)
Tolerance: ±10% (exact match required)
Core Material & Type: Ferrite, unshielded drum core (exact match required)
Mounting & Package: Through-hole, radial vertical cylinder (exact match required)
Current Rating: Minimum 7A (equal or higher acceptable)
Operating Temperature Range: -55°C ~ 105°C (equal or wider acceptable)

Two substitute parts meet these criteria: the Bourns 1130-101K-RC (higher current rating, active status) and the Hammond Manufacturing 1539M14 (equivalent specifications, active status).

Engineering Selection Recommendations

Bourns 1130-101K-RC: This substitute offers active product status with higher current capacity (9A vs. 7A), providing design margin for applications approaching the original 7A limit. Identical inductance, DCR, and tolerance specifications ensure direct functional equivalence. Smaller physical dimensions (1.100" diameter, 0.840" height) may require PCB layout verification for space-constrained designs. ROHS3 compliance and full temperature range specification (-55°C ~ 105°C) match the original part.

Hammond Manufacturing 1539M14: This substitute provides direct dimensional and electrical equivalence to the 5614-RC, with identical 7A current rating, inductance, and DCR specifications. Active product status ensures long-term availability. Physical dimensions match the original part exactly (1.220" diameter, 1.110" height), eliminating layout concerns. Operating temperature range is not specified in available data. ROHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 1130-101K-RC replace the 5614-RC in all applications?

A: Yes, from an electrical standpoint. The 1130-101K-RC meets all critical parameters: 100µH inductance, 34mOhm DCR, ±10% tolerance, and ferrite unshielded drum core construction. The higher 9A current rating provides additional design margin. However, the smaller physical dimensions (1.100" diameter vs. 1.220") require verification that the component fits within the PCB layout constraints of the original design.

Q: What are the key differences between the two substitutes?

A: The Bourns 1130-101K-RC offers higher current capacity (9A) and smaller physical size. The Hammond 1539M14 maintains identical dimensions and current rating to the original 5614-RC. Both are active products with ROHS3 compliance. Selection depends on available board space and current margin requirements.

Q: Are there any compliance or certification concerns with these substitutes?

A: Both substitutes carry ROHS3 compliance and EAR99 ECCN classification, matching the original part. The 1130-101K-RC explicitly specifies the full operating temperature range (-55°C ~ 105°C). The 1539M14 does not provide operating temperature data in available documentation.

Q: Can these parts be used interchangeably on the same PCB?

A: The 1539M14 can be used as a direct drop-in replacement due to identical dimensions. The 1130-101K-RC requires PCB layout verification due to its smaller footprint (1.100" diameter vs. 1.220"), though the radial through-hole mounting type remains unchanged.

Q: Which substitute should be selected for new designs?

A: Both parts are suitable for new designs. The 1130-101K-RC is recommended for applications where current margin or compact form factor is beneficial. The 1539M14 is recommended when maintaining identical physical dimensions to legacy designs is required.
