Bourns 9130-56 Equivalent & Substitute Parts

Part Overview

The Bourns 9130-56 is a 33 µH unshielded drum core wirewound inductor rated for 130 mA with a maximum DC resistance of 3.4 Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 9130-56 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and legacy system support.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan ER1025-56KR is the qualified substitute for the obsolete Bourns 9130-56. Both components share identical electrical specifications, physical dimensions, and environmental ratings. The ER1025-56KR maintains active product status and current manufacturing availability, making it suitable for new designs and replacement applications.

Both parts carry equivalent compliance classifications: RoHS non-compliant, REACH Unaffected, and ECCN EAR99. The ER1025-56KR is supplied in Tape & Reel packaging, which differs from the original part's packaging specification but does not affect functional compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: What makes the API Delevan ER1025-56KR a direct substitute for the Bourns 9130-56?

A: The ER1025-56KR matches all critical electrical parameters: 33 µH inductance at ±10% tolerance, 130 mA current rating, 3.4 Ohm maximum DC resistance, ferrite core construction, and identical Q factor and self-resonant frequency specifications. Physical dimensions and through-hole axial mounting are identical. Operating temperature range and frequency characteristics are equivalent.

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

A: Both parts share identical compliance classifications: RoHS non-compliant, REACH Unaffected, and ECCN EAR99. No regulatory differences exist that would affect substitution.

Q: Does the packaging difference affect compatibility?

A: The ER1025-56KR is supplied in Tape & Reel packaging while the original 9130-56 packaging is not specified. For through-hole axial components, packaging format does not affect electrical performance or mechanical fit in circuit board applications.

Q: Can the ER1025-56KR be used in legacy designs originally specified for the 9130-56?

A: Yes. Electrical and mechanical equivalence across all specified parameters supports direct substitution in existing circuit designs without modification.
