Bourns 1130-8R2M Fixed Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 1130-8R2M is an 8.2 µH unshielded drum core wirewound inductor rated for 21 A continuous current with a maximum DC resistance of 4 mOhm. This through-hole radial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring stable inductance at 1 kHz test frequency.

The 1130-8R2M is classified as obsolete. Equivalent substitute parts are available to maintain design continuity and ensure procurement flexibility for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1130-8R2M are classified based on electrical and mechanical parameter alignment:

Direct Substitutes maintain identical electrical specifications (8.2 µH inductance, 21 A current rating, 4 mOhm DCR) and physical form factor (radial, vertical cylinder through-hole package). These parts are interchangeable without circuit redesign.

Similar Substitutes share the same inductance value (8.2 µH), DC resistance (4 mOhm), and physical package configuration but operate at a reduced current rating (17.6 A versus 21 A). These parts are suitable for applications where the lower current rating meets design requirements.

The critical parameters determining substitution eligibility are:

• Inductance value: 8.2 µH
• DC Resistance: 4 mOhm Max
• Package type: Radial, Vertical Cylinder Through Hole
• Physical dimensions: 1.100" Dia × 0.840" Height
• Operating temperature range: -55°C to 105°C

Engineering Selection Recommendations

For Direct Replacement (1130-8R2M-RC): This Bourns part is the primary substitute for the obsolete 1130-8R2M. It provides identical electrical and mechanical specifications with the advantage of active product status and RoHS3 compliance. This part is suitable for all applications previously using the 1130-8R2M without circuit modification.

For Similar Substitution (IHB3BV8R2M or IHB3EB8R2M): These Vishay Dale inductors are suitable only when the application current requirement does not exceed 17.6 A. Both parts maintain the same inductance (8.2 µH) and DC resistance (4 mOhm) specifications. Selection between these two Vishay parts should be based on inventory availability and procurement lead times.

Compliance Considerations: The 1130-8R2M-RC offers RoHS3 compliance, making it the preferred choice for new designs and applications subject to environmental regulations. The original 1130-8R2M is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 1130-8R2M-RC be used as a direct replacement for the 1130-8R2M?

A: Yes. The 1130-8R2M-RC is electrically and mechanically identical to the 1130-8R2M, with identical inductance (8.2 µH), current rating (21 A), DC resistance (4 mOhm), and physical dimensions. No circuit redesign is required.

Q: What is the difference between the Bourns 1130-8R2M-RC and the Vishay Dale IHB3EB8R2M?

A: Both parts share the same inductance (8.2 µH) and DC resistance (4 mOhm). The primary difference is the current rating: the Bourns part is rated for 21 A, while the Vishay Dale part is rated for 17.6 A. The Bourns part is suitable for higher current applications.

Q: Are the Vishay Dale IHB3BV8R2M and IHB3EB8R2M interchangeable?

A: Both Vishay Dale parts have identical electrical specifications (8.2 µH, 17.6 A, 4 mOhm) and physical package configuration. Selection should be based on inventory availability and procurement lead times.

Q: What packaging options are available for these inductors?

A: The 1130-8R2M is supplied in standard through-hole radial, vertical cylinder configuration. The 1130-8R2M-RC is available in bulk packaging. All parts maintain the same physical form factor: 1.100" diameter × 0.840" height.

Q: Are these inductors suitable for high-temperature applications?

A: Yes. All parts in this family operate across the temperature range of -55°C to 105°C, making them suitable for industrial and automotive applications within this range.

Q: What is the inductance tolerance for these parts?

A: The Bourns 1130-8R2M and 1130-8R2M-RC are specified with ±20% inductance tolerance at 1 kHz test frequency. Tolerance specifications for the Vishay Dale parts are not provided in the available data.
