Bourns 1130-182K Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 1130-182K is a 1.8 mH unshielded drum core wirewound inductor rated for 1.6 A continuous current with a maximum DC resistance of 705 mOhm. This through-hole radial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance values in compact form factors.

The 1130-182K has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this inductor specification.

Substitute Part Grouping Explanation

Substitute parts for the Bourns 1130-182K are identified based on strict electrical and mechanical parameter matching within acceptable tolerances for through-hole radial inductor applications. The substitution criteria are:

Primary Matching Parameters:

• Inductance value: 1.8 mH (±10% tolerance maintained)
• DC resistance: 705 mOhm maximum
• Core type: Ferrite, unshielded wirewound construction
• Mounting: Through-hole radial vertical cylinder package
• Operating temperature range: -55°C to 105°C minimum
• Physical form factor: Compatible radial vertical cylinder dimensions

Substitute Parts Identified:

• Vishay Dale IHB3BV182K
• Vishay Dale IHB3EB182K

Both substitute parts maintain the critical electrical specifications (1.8 mH inductance, 705 mOhm DC resistance) and physical package compatibility required for direct substitution in applications designed for the 1130-182K.

Parameter Comparison

Engineering Selection Recommendations

Current Availability Consideration: The Bourns 1130-182K is obsolete. The Vishay Dale IHB3BV182K and IHB3EB182K substitutes are available in production quantities (1012 and 1004 units respectively), providing reliable supply chain alternatives.

Current Rating Differential: The substitute parts are rated for 1.3 A continuous current, compared to the original 1.6 A rating. Applications operating at or near the 1.6 A maximum must be evaluated to confirm that 1.3 A rating is acceptable for the intended circuit function. If the application requires the full 1.6 A capability, alternative inductors with higher current ratings must be sourced.

Electrical Equivalence: Both substitute parts maintain the 1.8 mH inductance and 705 mOhm DC resistance specifications, ensuring electrical performance compatibility for circuits designed around these parameters.

Compliance and Regulatory Status: The original Bourns 1130-182K is RoHS non-compliant. Compliance requirements for the substitute parts should be verified against current system-level regulatory requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale IHB3BV182K or IHB3EB182K be used as direct replacements for the Bourns 1130-182K?

A: Both Vishay Dale parts maintain the same inductance value (1.8 mH), DC resistance (705 mOhm), and through-hole radial vertical cylinder package configuration. However, the current rating is reduced from 1.6 A to 1.3 A. Direct substitution is valid only if the application circuit operates at or below 1.3 A continuous current.

Q: What is the difference between the IHB3BV182K and IHB3EB182K?

A: Both parts share identical electrical specifications (1.8 mH, 1.3 A, 705 mOhm) and package type. The designation difference (BV vs. EB) reflects internal manufacturing or series variations within the Vishay Dale IHB product line. Selection between these two parts can be based on availability and lead time.

Q: Are there any physical dimension differences between the original and substitute parts?

A: The original Bourns 1130-182K specifies a diameter of 1.100" (27.94 mm) and maximum seated height of 0.840" (21.34 mm). Physical dimensions for the Vishay Dale substitutes are not provided in the available data. PCB layout compatibility should be verified before final component selection.

Q: What should be considered if my application requires the full 1.6 A current rating?

A: The substitute parts are rated for 1.3 A maximum. If the circuit design requires 1.6 A continuous current capability, alternative inductors with higher current ratings and matching inductance specifications must be identified and evaluated.

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

A: The Bourns 1130-182K is RoHS non-compliant. Compliance status for the Vishay Dale IHB3BV182K and IHB3EB182K should be verified against your system-level regulatory requirements and procurement specifications.
