M80-8350722 Equivalent & Substitute Parts

Part Overview

The M80-8350722 is a surface mount, right-angle rectangular connector header manufactured by Harwin Inc. as part of the Datamate L-Tek series. This 7-position connector operates at 2.2A and 800V with a 2.00mm pitch and is designed for board-to-board or cable applications. The part is currently listed as obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The M80-8370742 qualifies as a direct substitute for the M80-8350722 based on the following critical parameters:

• Connector Type & Configuration: Both are header connectors with male pins, 7 positions, 2.00mm pitch, surface mount right-angle orientation, and 4-wall shrouding
• Electrical Ratings: Identical current (2.2A) and voltage (800V) ratings
• Thermal Range: Matching operating temperature range of -55°C to 125°C
• Material & Construction: Both use copper alloy contacts with gold mating finish and polyphenylene sulfide (PPS) glass-filled insulation
• Mechanical Interface: Same insulation height (0.157" / 4.00mm), contact shape (circular), and board-to-board or cable style
• Compliance: Both carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity level

The primary differences are product status (M80-8370742 is active versus obsolete M80-8350722), fastening mechanism (latch holder versus friction lock), and contact finish post material (tin versus tin-lead), which do not affect functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The M80-8370742 is the appropriate substitute for the obsolete M80-8350722. The substitute part maintains all critical electrical and mechanical parameters required for functional equivalence while offering the advantage of active product status and ROHS3 compliance. The shift from friction lock to latch holder fastening and the change in post contact finish from tin-lead to tin do not compromise electrical performance or mechanical compatibility in standard board-to-board or cable connection applications. For new designs or component refresh cycles, the M80-8370742 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can M80-8370742 be used as a direct replacement for M80-8350722 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (7), electrical ratings (2.2A, 800V), operating temperature range (-55°C to 125°C), and mechanical form factor (surface mount, right-angle, 4-wall shrouded). The fastening mechanism difference (latch holder versus friction lock) and post finish material change do not affect functional compatibility.

Q: What is the significance of the product status change from obsolete to active?

A: The M80-8350722 is no longer manufactured or supported by Harwin Inc. The M80-8370742 is an active product with ongoing manufacturing and availability, ensuring long-term component supply and technical support for new procurements and design revisions.

Q: Does the RoHS compliance difference impact substitution?

A: The M80-8370742 is ROHS3 compliant while the M80-8350722 is non-compliant. For applications subject to RoHS regulations or customer requirements, the M80-8370742 provides regulatory alignment. For legacy systems without RoHS mandates, this difference does not affect electrical or mechanical performance.

Q: Are there packaging differences between these parts?

A: The M80-8350722 packaging is not specified in the available data. The M80-8370742 is supplied in tube packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: What is the difference between friction lock and latch holder fastening?

A: Both fastening types secure the mated connector pair. Friction lock relies on contact pressure, while latch holder uses a mechanical locking feature. Both provide equivalent retention in standard applications. Verify mating connector compatibility if the mating side is not being replaced.
