Bourns 2107-H Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2107-H is a 33 µH unshielded toroidal inductor rated for 5 A continuous current with a maximum DC resistance of 29 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the Bourns 2100 series. The 2107-H has been designated as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2107-H is determined by strict equivalence across the following critical parameters:

• Inductance value: 33 µH
• Inductance tolerance: ±15%
• Current rating: 5 A minimum
• DC resistance: 29 mOhm maximum
• Toroidal core type with unshielded construction
• Through-hole radial, horizontal mounting configuration
• Physical dimensions: 0.860" diameter, 0.450" maximum seated height
• Operating temperature range: -55°C to 105°C
• Test frequency: 1 kHz

The Bourns 2107-H-RC meets all these criteria and serves as the direct active equivalent. Packaging differences (tape and reel versus bulk) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2107-H-RC is the direct equivalent for the obsolete 2107-H. Both parts are manufactured by Bourns Inc. and share identical electrical and mechanical specifications. The primary distinction is product status: the 2107-H is obsolete while the 2107-H-RC remains active in production.

For new designs or ongoing procurement, the 2107-H-RC is the appropriate selection. This part offers the additional advantage of ROHS3 compliance, whereas the original 2107-H is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 export classification.

Packaging format differs between the two parts (the 2107-H-RC is supplied in bulk packaging), but this does not affect electrical performance or mechanical fit in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 2107-H-RC be used as a direct replacement for the 2107-H?

A: Yes. The 2107-H-RC is electrically and mechanically identical to the 2107-H. All critical parameters—inductance, current rating, DC resistance, physical dimensions, and operating temperature range—are equivalent. The primary difference is that the 2107-H-RC is an active product while the 2107-H is obsolete.

Q: What is the difference between the 2107-H and 2107-H-RC?

A: The parts are functionally identical. The 2107-H-RC differs in packaging format (bulk versus tape and reel) and compliance status (ROHS3 compliant versus RoHS non-compliant). Both are manufactured by Bourns Inc. as part of the 2100 series.

Q: Are there any compatibility concerns when substituting the 2107-H-RC for the 2107-H?

A: No compatibility concerns exist. Both parts feature identical through-hole radial, horizontal mounting configurations and physical dimensions. PCB layout and assembly procedures require no modification.

Q: Does the 2107-H-RC meet current regulatory requirements?

A: Yes. The 2107-H-RC is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The obsolete 2107-H does not carry ROHS3 compliance.

Q: What is the inductance tolerance for these parts?

A: Both the 2107-H and 2107-H-RC carry an inductance tolerance of ±15%, measured at 1 kHz.
