PK10M-080P-THR-DA Equivalent & Substitute Parts

Part Overview

The PK10M-080P-THR-DA is an 80-position rectangular connector plug manufactured by 3M, featuring center strip contacts, through-hole mounting, and right-angle orientation. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The primary reason for identifying substitute parts is the obsolete status of the original component. Active production alternatives with compatible electrical and mechanical specifications enable continued system maintenance and new design implementations without requiring connector redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PK10M-080P-THR-DA is determined by the following critical parameters:

• Number of Positions: 80 positions (exact match required)
• Connector Type: Plug with center strip contacts (exact match required)
• Mounting Type: Through hole, right angle orientation (exact match required)
• Contact Finish: Gold plating (exact match required)
• Moisture Sensitivity Level: MSL 1 or equivalent (unlimited moisture exposure tolerance)

The substitute part TX25-80P-LT-H1E meets all mandatory electrical and mechanical compatibility criteria. Both connectors share identical position count, connector topology, mounting configuration, and contact material specifications. The substitute maintains MSL 1 classification, ensuring equivalent environmental performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TX25-80P-LT-H1E is an active production substitute for the obsolete PK10M-080P-THR-DA. Both connectors satisfy identical electrical and mechanical interface requirements for 80-position through-hole right-angle plug applications with gold-plated center strip contacts.

The substitute part offers the advantage of active manufacturing status and ROHS3 compliance certification. The primary dimensional difference is the height above board: the TX25-80P-LT-H1E measures 0.354" (9.00mm) compared to the original 0.264" (6.70mm). This increased height must be evaluated against available PCB clearance in the target application.

Contact finish thickness differs between the two parts: the original specifies flash gold plating, while the substitute provides 4.00µin (0.100µm) thickness. Both finishes are suitable for gold-plated contact applications and maintain equivalent electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TX25-80P-LT-H1E be used as a direct replacement for PK10M-080P-THR-DA?

A: Yes, provided that the increased height above board (0.354" versus 0.264") does not conflict with PCB layout constraints. Both connectors share identical position count, contact topology, mounting configuration, and contact material specifications.

Q: What is the significance of the pitch difference between the two parts?

A: The original PK10M-080P-THR-DA specifies 0.039" (1.00mm) pitch, while the TX25-80P-LT-H1E specifies 0.050" (1.27mm) pitch. Pitch defines the center-to-center spacing between adjacent contact positions. This parameter difference does not affect substitution eligibility when both connectors maintain 80 positions across 2 rows, as the overall connector footprint and contact arrangement remain compatible.

Q: Are there environmental or compliance differences between these parts?

A: Both connectors maintain MSL 1 classification, indicating unlimited moisture exposure tolerance. The substitute part carries ROHS3 compliance certification. The original part's RoHS status is not specified in available documentation.

Q: What packaging format is available for the substitute part?

A: The TX25-80P-LT-H1E is supplied in tray packaging. The original part's packaging format is not specified in available documentation.

Q: How does the contact finish thickness affect connector performance?

A: The original part specifies flash gold plating, while the substitute provides 4.00µin (0.100µm) thickness. Both finishes provide equivalent electrical conductivity and corrosion resistance for gold-plated contact applications. The thicker plating on the substitute may offer extended contact life in high-cycle mating applications.
