Equivalent & Substitute Parts for Bourns 5620-RC 100µH Wirewound Inductor

Part Overview

The Bourns 5620-RC is a 100µH unshielded drum core wirewound inductor rated for 9.8A continuous current with a maximum DC resistance of 27mOhm. This through-hole radial component operates across the -55°C to 105°C temperature range and is designed for applications requiring fixed inductance in power supply filtering, energy storage, and signal conditioning circuits.

The 5620-RC series has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for legacy systems and new designs requiring compatible performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Bourns 1140-101K-RC: This substitute offers enhanced performance within the same manufacturer ecosystem. The increased current rating (10.5A versus 9.8A) and reduced DC resistance (25mOhm versus 27mOhm) provide operational margin in current-limited applications. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and REACH unaffected status maintain regulatory alignment with the original component.

Hammond Manufacturing 1539M20: This substitute maintains electrical equivalence at the specified 9.8A current rating with improved DC resistance (25mOhm). Active product status supports ongoing procurement. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements. Physical dimensions match the original component (1.500" diameter, 1.110" seated height), ensuring mechanical compatibility in existing PCB layouts.

Both substitutes are suitable for direct replacement in applications designed for the 5620-RC. Selection between them depends on supply chain preference, procurement lead times, and design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1140-101K-RC replace the 5620-RC in all applications?

A: Yes. The 1140-101K-RC meets or exceeds all electrical specifications of the 5620-RC. The higher current rating (10.5A) and lower DC resistance (25mOhm) are compatible with designs specified for 9.8A at 27mOhm maximum. Physical package dimensions are identical.

Q: What is the difference between the Bourns and Hammond substitutes?

A: Both parts maintain the 100µH inductance and ±10% tolerance. The Bourns 1140-101K-RC provides 10.5A current capacity; the Hammond 1539M20 provides 9.8A. Both achieve 25mOhm maximum DC resistance. The Bourns part specifies -55°C to 105°C operating range; Hammond specifications do not include operating temperature data in the provided documentation.

Q: Are there mechanical compatibility concerns when substituting?

A: No. All three parts share identical package configurations: radial, vertical cylinder mounting with 1.500" diameter and 1.110" seated height. Through-hole mounting compatibility is maintained across all substitutes.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both the Bourns 1140-101K-RC and Hammond 1539M20 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 5620-RC.

Q: Why is the 5620-RC marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The listed substitutes are active products from the same or equivalent manufacturers, ensuring continued availability for replacement and new designs.
