M80-7172405 Equivalent & Substitute Parts

Part Overview

The M80-7172405 is a 26-position receptacle connector from Harwin Inc.'s Datamate Mix-Tek series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch and through-hole solder termination. This connector features gold-plated contacts, screw lock fastening, and operates across -55°C to 125°C. The product is currently obsolete, making equivalent substitutes necessary for new designs or maintenance applications requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

The MPSC-01-24-01-7.70-01-L-V-LC from Samtec Inc. qualifies as a functional substitute based on the following alignment of critical parameters:

• Position Count & Configuration: Both connectors provide 26 positions (24 + 2 Power) with all positions loaded
• Pitch & Row Spacing: Both maintain 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Both use through-hole solder termination for PCB integration
• Contact Finish: Both feature gold-plated mating contacts
• Operating Temperature Range: Both support -55°C to 125°C operation
• Compliance: Both are ROHS3 compliant and UL94 V-0 rated
• Moisture Sensitivity: Both are MSL 1 (Unlimited)

Differences in fastening type (screw lock vs. push-pull), number of rows (3 vs. 4), contact geometry (circular vs. square), and insulation material do not prevent functional substitution when mechanical envelope and PCB layout accommodate the alternative design.

Parameter Comparison

Engineering Selection Recommendations

The MPSC-01-24-01-7.70-01-L-V-LC is an active product from an established connector manufacturer, providing supply continuity for applications currently using the obsolete M80-7172405. Both connectors meet identical compliance requirements (ROHS3, UL94 V-0) and operate within the same temperature range.

Selection of the Samtec substitute requires verification that the mechanical envelope accommodates the increased insulation height (0.298" vs. 0.247") and the transition from screw lock to push-pull fastening. The change in row configuration from 3 to 4 rows and the different contact geometry necessitate PCB layout review to confirm compatibility with existing mating connectors and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the MPSC-01-24-01-7.70-01-L-V-LC directly replace the M80-7172405 without PCB modifications?

A: Direct replacement requires verification of mechanical fit. The substitute has a taller insulation height (0.298" vs. 0.247") and uses push-pull fastening instead of screw lock. PCB layout and mating connector compatibility must be confirmed before implementation.

Q: Are the contact finishes equivalent between these two connectors?

A: Both use gold-plated mating contacts. The M80-7172405 specifies 12.0µin (0.30µm) thickness, while the MPSC-01-24-01-7.70-01-L-V-LC specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion protection and electrical performance for the specified operating conditions.

Q: What is the difference in contact geometry between these connectors?

A: The M80-7172405 uses circular contacts made from beryllium copper, while the MPSC-01-24-01-7.70-01-L-V-LC uses square contacts made from copper alloy and phosphor bronze. Contact geometry affects mating force and insertion characteristics; compatibility depends on the mating connector design.

Q: Do both connectors support the same operating temperature range?

A: Yes, both connectors operate across -55°C to 125°C and are rated UL94 V-0 for flammability. Thermal performance is equivalent for this temperature range.

Q: What are the packaging differences?

A: The M80-7172405 packaging is not specified in available data. The MPSC-01-24-01-7.70-01-L-V-LC is supplied in trays. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both connectors RoHS compliant?

A: Yes, both are ROHS3 compliant and unaffected by REACH regulations. Both carry EAR99 ECCN classification and the same HTSUS code (8536.69.4040).
