Bourns 2312-H Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2312-H is a 100 µH unshielded toroidal inductor rated for 7 A continuous current with a maximum DC resistance of 37 mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2312-H is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. Direct equivalents maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2312-H is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical inductance value of 100 µH with ±15% tolerance
• Identical current rating of 7 A
• Identical maximum DC resistance of 37 mOhm
• Identical core material (iron powder)
• Identical shielding configuration (unshielded)
• Identical mounting type (through hole)
• Identical package geometry (radial, horizontal orientation)
• Identical physical dimensions (1.280" diameter, 0.650" height)
• Identical operating temperature range (-55°C to 105°C)

The Bourns 2312-H-RC meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2312-H-RC is the direct equivalent substitute for the obsolete 2312-H. Both parts are manufactured by Bourns Inc. within the 2300 series and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the 2312-H is obsolete and RoHS non-compliant, while the 2312-H-RC is active and ROHS3 compliant. For new designs and ongoing production requiring this 100 µH, 7 A toroidal inductor, the 2312-H-RC provides equivalent performance with improved supply availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 2312-H-RC be used as a direct replacement for the 2312-H in existing designs?

A: Yes. The 2312-H-RC maintains identical electrical specifications (100 µH inductance, 7 A current rating, 37 mOhm maximum DC resistance) and mechanical dimensions (1.280" diameter, 0.650" height). Both are through-hole radial, horizontal toroidal inductors with iron powder cores. No circuit modifications are required.

Q: What is the difference between the 2312-H and 2312-H-RC?

A: The parts are electrically and mechanically identical. The 2312-H is obsolete and RoHS non-compliant. The 2312-H-RC is active production and ROHS3 compliant. The packaging differs: 2312-H uses standard packaging while 2312-H-RC is supplied in bulk packaging.

Q: Are there any compliance considerations when switching from 2312-H to 2312-H-RC?

A: Yes. The 2312-H-RC is ROHS3 compliant, whereas the 2312-H is RoHS non-compliant. Both maintain REACH Unaffected status. If your application or region requires RoHS compliance, the 2312-H-RC is the appropriate choice.

Q: Will the 2312-H-RC fit the same PCB footprint as the 2312-H?

A: Yes. Both parts have identical physical dimensions: 1.280" (32.51 mm) diameter and 0.650" (16.51 mm) height. The radial, horizontal through-hole mounting configuration is identical, ensuring direct PCB compatibility.

Q: What is the operating temperature range for both parts?

A: Both the 2312-H and 2312-H-RC operate across -55°C to 105°C, providing identical thermal performance across industrial and commercial temperature ranges.
