M80-8370645 Equivalent & Substitute Parts

Part Overview

The M80-8370645 is a surface mount, right-angle rectangular connector header manufactured by Harwin Inc. as part of the Datamate L-Tek series. This 6-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 functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M80-8370645 is determined by the following critical parameters:

• Manufacturer series compatibility (Datamate L-Tek)
• Mating pitch (2.00mm)
• Mounting type (Surface Mount, Right Angle)
• Connector type (Header with Male Pin contacts)
• Shrouding configuration (Shrouded - 4 Wall)
• Electrical ratings (2.2A current, 800V voltage minimum)
• Termination method (Solder)
• Fastening type (Latch Holder)
• Insulation material and flammability rating (PPS, Glass Filled; UL94 V-0)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The M80-8370742 qualifies as a substitute based on matching all critical parameters. The primary difference is the number of positions (7 vs. 6), which represents a functional extension rather than a deviation from core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The M80-8370742 is the manufacturer-recommended substitute for the obsolete M80-8370645. Both connectors maintain identical electrical and mechanical specifications within the Datamate L-Tek series, including current and voltage ratings, operating temperature range, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The M80-8370742 is currently in active production status, ensuring long-term availability and supply chain continuity. The 7-position configuration provides additional contact capacity while maintaining full backward compatibility with the core electrical and mechanical interface parameters.

The only material difference is the post contact finish: the M80-8370645 features gold plating on posts, while the M80-8370742 uses tin plating. Both finishes are compatible with standard solder termination processes and do not affect mating performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the M80-8370742 directly replace the M80-8370645 in existing designs?

A: The M80-8370742 is electrically and mechanically compatible with the M80-8370645 for all core interface parameters. The primary consideration is the increased number of positions (7 vs. 6). If your design uses only 6 positions, the additional position remains unused. If your PCB layout accommodates the 7-position footprint, direct substitution is feasible.

Q: What is the significance of the contact finish difference (Gold vs. Tin)?

A: Both gold and tin finishes are standard for solder termination and provide equivalent electrical performance. The choice between them does not affect mating reliability or signal integrity. Tin plating is more cost-effective and equally suitable for standard applications.

Q: Why is the M80-8370645 listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation decisions based on market demand and product line consolidation. The M80-8370742 represents the active continuation within the Datamate L-Tek series.

Q: Are there any PCB layout considerations when switching from 6-position to 7-position?

A: The 2.00mm pitch remains constant. The 7-position connector requires additional board space for the extra contact position. Verify that your PCB layout can accommodate the extended footprint before implementation.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the M80-8370645 and M80-8370742 are ROHS3 Compliant and REACH Unaffected, with identical UL94 V-0 flammability ratings and operating temperature specifications.
