M80-8911601 Equivalent & Substitute Parts

Part Overview

The M80-8911601 is a 16-position receptacle connector from Harwin Inc.'s Datamate L-Tek series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch mating. This connector features through-hole solder termination, gold-plated mating contacts, and tin-lead post finish. The product is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M80-8911601 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Number of positions (16)
• Pitch specification (0.079" / 2.00mm mating pitch)
• Row configuration (2 rows)
• Mounting method (Through Hole)
• Contact finish at mating surface (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)

The M80-8501642 qualifies as a direct substitute based on these parameters. Both connectors share identical mechanical and electrical specifications for mating interface, row spacing, insulation dimensions, and environmental ratings. Differences exist in contact post length, post finish material, insulation material composition, voltage rating, and RoHS compliance status, which do not preclude substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The M80-8501642 is the primary substitute for the obsolete M80-8911601. Both connectors maintain identical mating interface geometry, row configuration, and environmental operating specifications. The substitute part is currently in active production status with improved RoHS3 compliance, addressing regulatory requirements for new designs and system updates.

Key considerations for selection:

Contact post length differs between the two parts (0.051" versus 0.118"), requiring verification of PCB pad depth and solder joint geometry during board layout review. The substitute part features a longer post, providing increased solder fillet engagement.

Voltage rating increases from 120V to 800V in the substitute part, representing an enhancement in electrical capability with no negative impact on applications designed for the original specification.

Post finish material changes from tin-lead to tin in the substitute part. This transition aligns with RoHS3 compliance requirements and does not affect mechanical or electrical performance in standard solder joint applications.

Insulation material composition differs (polyester glass-filled versus polyamide nylon 4/6 glass-filled), with both materials meeting UL94 V-0 flammability requirements and maintaining equivalent thermal and mechanical properties within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can M80-8501642 be used as a direct replacement for M80-8911601 in existing designs?

A: Yes. The substitute part maintains identical mating pitch, row spacing, contact finish at the mating interface, mounting method, and environmental ratings. PCB layout compatibility is confirmed for standard through-hole solder applications. Contact post length variation requires verification of existing pad geometry to ensure adequate solder joint formation.

Q: What is the primary reason for substitution?

A: The M80-8911601 is obsolete. The M80-8501642 provides equivalent functionality with active production status and improved regulatory compliance (RoHS3).

Q: Are there packaging differences between these parts?

A: The M80-8911601 packaging specification is not provided. The M80-8501642 is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the higher voltage rating of M80-8501642 affect compatibility?

A: No. The increased voltage rating (800V versus 120V) represents enhanced electrical capability. Applications designed for 120V operation remain fully compatible.

Q: What impact does the post finish change have on soldering?

A: The transition from tin-lead to tin post finish does not affect solder joint quality or reliability in standard reflow or wave soldering processes. Tin finish is compatible with lead-free and traditional solder alloys.

Q: Are the mated stacking heights identical?

A: Yes. Both connectors provide identical mated stacking heights of 7.23mm and 7.85mm, ensuring mechanical compatibility in board-to-board applications.
