Bourns 1130-100K Equivalent & Substitute Parts

Part Overview

The Bourns 1130-100K is a 10 µH unshielded drum core wirewound inductor rated for 17 A continuous current with a maximum DC resistance of 6 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 in power conversion and filtering circuits.

The 1130-100K carries an 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 legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1130-100K is determined by strict equivalence across the following critical parameters:

• Inductance Value: 10 µH (exact match required)
• Current Rating: 17 A minimum (equal or higher acceptable)
• DC Resistance: 6 mOhm maximum (equal or lower acceptable)
• Tolerance: ±10% (equal or tighter acceptable)
• Core Material & Type: Ferrite, unshielded drum core (exact match required)
• Mounting Configuration: Through-hole radial, vertical cylinder (exact match required)
• Physical Envelope: 1.100" diameter, 0.840" height maximum (exact match required)
• Operating Temperature Range: -55°C to 105°C minimum (equal or wider acceptable)

The 1130-100K-RC qualifies as a direct substitute because it maintains identical electrical specifications, mechanical form factor, and thermal operating range while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 1130-100K-RC is the direct substitute for the obsolete 1130-100K. Both components are manufactured by Bourns Inc. within the same 1130 series and maintain identical electrical and mechanical specifications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 1130-100K carries obsolete status with RoHS non-compliant classification, while the 1130-100K-RC is an active product meeting ROHS3 compliance requirements. For new designs or systems requiring regulatory adherence to current environmental standards, the 1130-100K-RC is the appropriate selection. For legacy system maintenance where the original 1130-100K specification must be preserved, the 1130-100K-RC provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1130-100K-RC be used as a direct replacement for the 1130-100K?

A: Yes. The 1130-100K-RC is a direct substitute. Both parts share identical inductance (10 µH), current rating (17 A), DC resistance (6 mOhm max), tolerance (±10%), core type (ferrite unshielded drum core), mounting configuration (through-hole radial), physical dimensions (1.100" diameter, 0.840" height), and operating temperature range (-55°C to 105°C).

Q: What is the primary difference between these two parts?

A: The 1130-100K is obsolete and RoHS non-compliant, while the 1130-100K-RC is an active product with ROHS3 compliance. Electrical and mechanical performance are identical.

Q: Are there any packaging differences?

A: The 1130-100K is supplied in standard packaging, while the 1130-100K-RC is supplied in bulk packaging. Both maintain the same component specifications and form factor.

Q: Will the 1130-100K-RC fit the same PCB footprint as the 1130-100K?

A: Yes. Both components use identical through-hole radial mounting with the same physical envelope (1.100" diameter, 0.840" maximum height), ensuring direct PCB compatibility without layout modifications.

Q: Is the 1130-100K-RC suitable for applications requiring RoHS compliance?

A: Yes. The 1130-100K-RC meets ROHS3 compliance requirements, making it suitable for applications and markets with mandatory RoHS environmental standards.
