PM5022-151M Equivalent & Substitute Parts

Part Overview

The PM5022-151M is a 150 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.4 A with 250mOhm 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 acceptable tolerances while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM5022-151M is determined by the following critical parameters:

• Inductance Value: 150 µH (tolerance range ±20% acceptable)
• Current Rating: Minimum 1.4 A
• DC Resistance: Maximum 250mOhm to 270mOhm
• Saturation Current: Minimum 2.6 A
• Mounting Type: Surface Mount
• Physical Footprint: 18.30mm x 14.00mm base dimensions
• Shielding Configuration: Unshielded

Two categories of substitutes are identified:

Direct Manufacturer Substitutes (Bourns Inc.): PM5022-151M-RC and SDR1806-151KL maintain identical inductance, current rating, and saturation specifications with compatible physical dimensions and shielding characteristics.

Cross-Manufacturer Substitute (Eaton): UP5-151-R provides equivalent inductance and current handling with compatible DC resistance and physical form factor, though from a different manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

PM5022-151M-RC is the primary direct substitute. It is manufactured by Bourns Inc. within the same PM5022 series, maintains identical electrical specifications, and is currently in active production status. This part achieves ROHS3 compliance and offers an extended operating temperature range (-40°C ~ 125°C) compared to the obsolete original. Tape & Reel packaging supports automated assembly processes.

SDR1806-151KL serves as an alternative Bourns Inc. substitute from the SDR1806 series. It provides tighter inductance tolerance (±10% versus ±20%), identical current and saturation ratings, and ROHS3 compliance. Physical dimensions and height are identical to the main part. This option is suitable where improved inductance accuracy is required.

UP5-151-R is a cross-manufacturer substitute from Eaton's UNI-PAC™ 5 series. It maintains the 150 µH inductance, supports 1.5 A current rating (exceeding the 1.4 A requirement), and provides 250mOhm maximum DC resistance matching the original specification. Physical dimensions are marginally larger (18.40mm x 15.00mm footprint, 7.50mm height). This part is RoHS compliant and suitable for applications where cross-manufacturer sourcing is acceptable.

All three substitutes maintain unshielded configuration, surface mount mounting type, and saturation current of 2.6 A, ensuring functional compatibility within the specified electrical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can PM5022-151M-RC be used as a direct replacement for PM5022-151M?

A: Yes. Both parts share identical inductance (150 µH), current rating (1.4 A), saturation current (2.6 A), and physical dimensions (18.30mm x 14.00mm x 6.90mm). DC resistance increases from 250mOhm to 270mOhm, which remains within acceptable tolerance for most applications. PM5022-151M-RC is active production and ROHS3 compliant.

Q: What is the difference between SDR1806-151KL and PM5022-151M-RC?

A: Both are Bourns Inc. products with identical inductance, current, and saturation specifications. SDR1806-151KL offers tighter inductance tolerance (±10% versus ±20%) and is from a different product series (SDR1806 versus PM5022). Physical dimensions and height are identical. Selection depends on tolerance requirements and series preference.

Q: Can UP5-151-R be used in place of the PM5022-151M?

A: UP5-151-R is compatible for most applications. It maintains 150 µH inductance, supports 1.5 A current (exceeding the 1.4 A requirement), and provides 250mOhm maximum DC resistance. Physical dimensions are slightly larger (18.40mm x 15.00mm footprint, 7.50mm height). Verify PCB layout clearance before substitution.

Q: What is the impact of increased DC resistance in PM5022-151M-RC?

A: DC resistance increases from 250mOhm to 270mOhm, representing an 8% increase. This results in proportionally higher resistive losses and heat dissipation. For applications sensitive to power loss or thermal performance, evaluate the impact on circuit efficiency. For most general-purpose applications, this difference is negligible.

Q: Are all substitute parts RoHS compliant?

A: PM5022-151M-RC and SDR1806-151KL are ROHS3 compliant. UP5-151-R is RoHS compliant. The original PM5022-151M is RoHS non-compliant. All substitutes meet current environmental and regulatory standards.

Q: What is the difference in operating temperature range?

A: PM5022-151M operates -55°C ~ 105°C. PM5022-151M-RC and SDR1806-151KL extend to -40°C ~ 125°C. UP5-151-R operates -25°C ~ 105°C. Select based on application temperature requirements. The extended range of Bourns substitutes provides greater flexibility for extreme environment applications.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) packaging used by all substitutes is a manufacturing and handling format only. Electrical specifications remain identical to bulk packaging. TR format supports automated pick-and-place assembly processes.
