Bourns 1130-102K Equivalent & Substitute Parts

Part Overview

The Bourns 1130-102K is a 1 mH unshielded drum core wirewound inductor rated for 2 A continuous current with a maximum DC resistance of 426 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 standard radial vertical cylinder packaging.

The 1130-102K carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1130-102K are qualified based on the following critical parameters:

• Inductance value: 1 mH (exact match required)
• DC Resistance: 426 mOhm maximum (exact match required)
• Tolerance: ±10% (exact match required)
• Shielding: Unshielded (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Vertical Cylinder (exact match required)
• Physical dimensions: 1.100" Dia (27.94 mm) and 0.840" (21.34 mm) height (exact match required)
• Inductance Test Frequency: 1 kHz (exact match required)

The identified substitute parts meet all these critical parameters. Variations in current rating and operating temperature range are noted but do not disqualify substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Dale IHB3BV102K and IHB3EB102K are direct functional equivalents to the obsolete Bourns 1130-102K. Both substitute parts maintain identical inductance, DC resistance, tolerance, shielding, mounting type, and physical dimensions.

The IHB3BV102K carries ROHS3 compliance status, providing regulatory advantage for new designs and applications subject to RoHS requirements. The operating temperature range of -55°C to 130°C exceeds the original 1130-102K specification, offering extended thermal performance.

Current rating differences exist: the substitute parts are rated at 1.7 A versus the original 2 A rating. Selection between the original specification and substitute parts depends on actual circuit current requirements. Applications drawing 1.7 A or less can use either substitute without derating. Applications requiring the full 2 A rating must evaluate whether the 1.7 A substitute rating is acceptable for the specific design.

Both Vishay Dale parts are currently in active production with confirmed inventory availability, ensuring reliable sourcing for immediate and future requirements.

Frequently Asked Questions (FAQ)

Q: Can the IHB3BV102K or IHB3EB102K be used as direct replacements for the 1130-102K in existing designs?

A: Yes, both parts are direct functional equivalents. They share identical inductance (1 mH), DC resistance (426 mOhm), tolerance (±10%), shielding (unshielded), mounting type (through hole), and physical dimensions (1.100" Dia × 0.840" height). Substitution is valid provided circuit current does not exceed 1.7 A.

Q: What is the impact of the lower current rating on the substitute parts?

A: The substitute parts are rated at 1.7 A compared to the original 2 A rating. If your circuit operates at or below 1.7 A, the substitute parts perform identically. If your circuit requires the full 2 A rating, the substitute parts would operate outside their rated specification and should not be used.

Q: Are there compliance or regulatory differences between the original and substitute parts?

A: The IHB3BV102K is ROHS3 compliant, whereas the original 1130-102K is RoHS non-compliant. For applications subject to RoHS regulations, the IHB3BV102K provides regulatory compliance. The IHB3EB102K compliance status is not specified in available data.

Q: Do the substitute parts fit the same PCB footprint and through-hole spacing?

A: Yes. Both substitute parts maintain the identical radial vertical cylinder package with 1.100" diameter and 0.840" maximum seated height. PCB footprint and through-hole spacing are compatible without modification.

Q: What is the availability status of the substitute parts?

A: Both the IHB3BV102K and IHB3EB102K are active production parts with confirmed inventory. The IHB3BV102K has 876 units in stock, and the IHB3EB102K has 1060 units in stock, ensuring reliable component sourcing.
