PM3700-10 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The PM3700-10 is a 200 µH, 2-line common mode choke manufactured by Bourns Inc., designed for surface mount applications with a maximum current rating of 7A and DC resistance of 6mOhm. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The PM3700-10 operates across a temperature range of -55°C to 125°C and is packaged in a horizontal, 4-pad configuration with dimensions of 21.60mm × 21.60mm × 11.43mm maximum height.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM3700-10 is based on strict equivalence across the following critical parameters:

• Inductance value: 200 µH @ 1 kHz
• Number of lines: 2-line configuration
• Current rating: 7A maximum
• DC resistance: 6mOhm maximum
• Mounting type: Surface mount
• Physical footprint: 21.60mm × 21.60mm × 11.43mm
• Package configuration: Horizontal, 4-pad layout

The PM3700-10-RC meets all these criteria and represents a direct functional equivalent. The primary distinction between these parts is packaging format and product status, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The PM3700-10-RC is the direct substitute for the PM3700-10. Both components share identical electrical specifications and mechanical dimensions. The PM3700-10-RC is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance. The PM3700-10-RC is supplied in Tape & Reel format, which is standard for automated assembly processes, whereas the original PM3700-10 was supplied in bulk packaging.

For applications requiring RoHS compliance, the PM3700-10-RC is the only viable option from this substitution group. Both parts maintain equivalent performance across the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the PM3700-10-RC be used as a direct replacement for the PM3700-10?

A: Yes. The PM3700-10-RC is electrically and mechanically identical to the PM3700-10. Both components feature 200 µH inductance, 7A current rating, 6mOhm DCR, and identical physical dimensions. The parts are interchangeable at the circuit level.

Q: What is the difference between the PM3700-10 and PM3700-10-RC?

A: The primary differences are product status, packaging format, and RoHS compliance. The PM3700-10 is obsolete and supplied in bulk packaging with RoHS non-compliant status. The PM3700-10-RC is active, supplied in Tape & Reel format, and ROHS3 compliant.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your process uses manual or semi-automated placement, verify that your equipment supports standard 8mm or 12mm tape widths. The PM3700-10-RC uses standard 4-pad horizontal packaging compatible with conventional pick-and-place systems.

Q: Does the PM3700-10-RC meet RoHS requirements?

A: Yes. The PM3700-10-RC is ROHS3 compliant. If your application requires RoHS compliance, the PM3700-10-RC is the appropriate selection.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both the PM3700-10 and PM3700-10-RC maintain identical operating temperature range (-55°C to 125°C), inductance value (200 µH @ 1 kHz), current rating (7A), and DC resistance (6mOhm).
