PM628S-150-RC Equivalent & Substitute Parts

Part Overview

The PM628S-150-RC is a 15 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.7 A continuous current with a maximum DC resistance of 78 mOhm. This surface mount component is designed for applications requiring controlled inductance with ferrite core shielding in compact nonstandard packaging. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and environmental ratings can be maintained across alternative manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM628S-150-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 15 µH with ±30% tolerance
• Current rating: 1.7 A minimum continuous current capability
• DC resistance: 78 mOhm maximum
• Core type: Ferrite shielded drum core
• Saturation current: 1.3 A minimum
• Operating temperature range: -40°C to 125°C minimum
• Mounting: Surface mount, nonstandard package
• Physical dimensions: 6.80 mm × 6.80 mm footprint with 3.00 mm maximum height
• Compliance: RoHS3 and REACH requirements

The SRR6028-150Y from Bourns Inc. meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both PM628S-150-RC and SRR6028-150Y are active production components from Bourns Inc. with identical electrical specifications and mechanical compatibility. Selection between these parts may be based on inventory availability and supply chain considerations. The PM628S-150-RC currently has 647 units in stock, while the SRR6028-150Y has 1700 units available. Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting all regulatory requirements for industrial and commercial applications. The negligible 1 MHz difference in self-resonant frequency (23 MHz vs. 22 MHz) does not affect functional equivalence within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SRR6028-150Y be used as a direct replacement for PM628S-150-RC?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including inductance, current rating, DC resistance, core material, shielding, temperature range, and package dimensions. Both are active production components with identical compliance certifications.

Q: Are there any differences in performance between these two parts?

A: The self-resonant frequency differs by 1 MHz (PM628S-150-RC at 23 MHz, SRR6028-150Y at 22 MHz). This difference remains within acceptable tolerance for applications using these inductors within their specified frequency range and does not impact functional equivalence.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching inductance value (15 µH ±30%), current rating (1.7 A), DC resistance (78 mOhm max), core type (ferrite shielded), saturation current (1.3 A), operating temperature range (-40°C to 125°C), surface mount package dimensions (6.80 mm × 6.80 mm × 3.00 mm), and compliance certifications (RoHS3, REACH).

Q: Are both parts suitable for the same PCB layout and footprint?

A: Yes. Both parts have identical package dimensions of 6.80 mm × 6.80 mm with a maximum seated height of 3.00 mm, ensuring compatibility with the same PCB footprint and assembly process.

Q: What is the moisture sensitivity level for these inductors?

A: Both parts have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
