PM5022-101M Equivalent & Substitute Parts

Part Overview

The PM5022-101M is a 100 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.7 A continuous current with 190mOhm DC resistance. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within the specified operating parameters while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: inductance value (100 µH), current rating (minimum 1.7 A), DC resistance (190mOhm nominal or maximum specification), saturation current (3.2 A minimum), unshielded configuration, and surface mount nonstandard package with matching physical footprint (18.30mm x 14.00mm x 6.90mm maximum height).

The PM5022-101M-RC qualifies as a direct manufacturer equivalent, differing only in packaging format (Tape & Reel versus cut tape) and product status (Active versus Obsolete). The SDR1806-101KL and UP5-101-R are classified as similar alternatives, meeting all critical electrical parameters with minor variations in inductance tolerance, temperature range, and resonant frequency characteristics that do not affect functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

PM5022-101M-RC is the primary substitute for direct replacement. It maintains identical electrical specifications and physical footprint while offering active product status and ROHS3 compliance. The extended operating temperature range (-40°C to 125°C versus -55°C to 105°C) provides broader environmental coverage for most applications.

SDR1806-101KL serves as an alternative within the Bourns product family, offering tighter inductance tolerance (±10% versus ±20%) and improved frequency characteristics. Physical dimensions remain identical, ensuring PCB compatibility. ROHS3 compliance and active status support long-term supply chain continuity.

UP5-101-R from Eaton Electronics Division qualifies as a cross-manufacturer substitute with equivalent electrical performance. The slightly higher current rating (1.8 A versus 1.7 A) and marginally larger physical footprint (18.40mm x 15.00mm x 7.50mm) require PCB layout verification. RoHS compliance and active product status support procurement flexibility.

Selection between these alternatives depends on supply availability, compliance requirements, and physical space constraints on the target PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can PM5022-101M-RC be used as a direct replacement for PM5022-101M?

A: Yes. Both parts share identical inductance (100 µH), current rating (1.7 A), DC resistance (190mOhm), saturation current (3.2 A), and physical dimensions (18.30mm x 14.00mm x 6.90mm). The difference is packaging format and product status. PM5022-101M-RC is supplied in Tape & Reel format and maintains active manufacturing status.

Q: What are the key differences between SDR1806-101KL and PM5022-101M?

A: Both parts meet the core electrical requirements (100 µH, 1.7 A, 190mOhm DCR, 3.2 A Isat). SDR1806-101KL offers tighter inductance tolerance (±10% versus ±20%) and an extended operating temperature range (-40°C to 125°C). Physical footprint is identical. The SDR1806 series represents an alternative Bourns product line with improved specifications.

Q: Is UP5-101-R compatible with the original PM5022-101M footprint?

A: UP5-101-R has slightly larger dimensions (18.40mm x 15.00mm x 7.50mm versus 18.30mm x 14.00mm x 6.90mm). PCB layout verification is required to confirm clearance and placement compatibility. Electrical performance is equivalent across all critical parameters.

Q: What compliance differences exist between these substitutes?

A: PM5022-101M is RoHS non-compliant. PM5022-101M-RC and SDR1806-101KL are ROHS3 compliant. UP5-101-R is RoHS compliant. For applications requiring regulatory compliance, PM5022-101M-RC or SDR1806-101KL are preferred selections.

Q: Are there temperature range limitations when substituting these parts?

A: PM5022-101M operates from -55°C to 105°C. PM5022-101M-RC and SDR1806-101KL extend to -40°C to 125°C. UP5-101-R operates from -25°C to 105°C. Verify that the substitute part's temperature range meets application requirements, particularly for extreme environment specifications.

Q: How do saturation current ratings affect substitution?

A: PM5022-101M, PM5022-101M-RC, and SDR1806-101KL all specify 3.2 A saturation current. UP5-101-R specifies 3.0 A. For applications operating near saturation limits, the 0.2 A difference may be significant. Verify circuit peak current requirements against the selected substitute's Isat specification.

Q: What packaging considerations apply to these substitutes?

A: PM5022-101M is supplied in cut tape format. PM5022-101M-RC, SDR1806-101KL, and UP5-101-R are supplied in Tape & Reel format. Tape & Reel packaging supports automated assembly processes and is standard for high-volume production. Cut tape format is suitable for manual or low-volume assembly.
