PK10M-080P-TH4-DA Equivalent & Substitute Parts

Part Overview

The PK10M-080P-TH4-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 suitable substitute components essential for ongoing system maintenance and new design implementations. The part is designed for applications requiring high-density interconnection with gold-plated contacts and board-level retention features.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PK10M-080P-TH4-DA is based on the following critical parameters:

• Connector Type: Plug configuration with center strip contacts
• Position Count: 80-position capacity
• Mounting Configuration: Through-hole, right-angle orientation
• Contact Material: Gold plating for electrical performance
• Board-Level Features: Board lock and solder retention capability
• Environmental Classification: MSL 1 rating for unlimited moisture exposure

The TX25-80P-LT-H1E from JAE Electronics meets these core functional requirements. Differences in pitch specification (0.050" vs. 0.039") and height above board (0.354" vs. 0.421") represent design variations within the 80-position, right-angle plug category and do not preclude substitution where mechanical envelope constraints permit.

Parameter Comparison

Engineering Selection Recommendations

The TX25-80P-LT-H1E is an active product with current manufacturing support and ROHS3 compliance, addressing the obsolescence status of the PK10M-080P-TH4-DA. Both connectors maintain MSL 1 classification and support 80-position, right-angle through-hole applications.

Selection of the TX25-80P-LT-H1E requires verification that the pitch difference (0.050" vs. 0.039") and reduced height above board (0.354" vs. 0.421") are compatible with the target application's PCB layout and mechanical envelope. The TX25-80P-LT-H1E omits the solder retention feature present in the original part; applications dependent on this feature require design review.

Frequently Asked Questions (FAQ)

Q: Can the TX25-80P-LT-H1E directly replace the PK10M-080P-TH4-DA?

A: Direct replacement is possible only if the application tolerates the pitch difference (0.050" vs. 0.039") and the reduced height above board (0.354" vs. 0.421"). PCB layout and mechanical clearance must be evaluated for compatibility.

Q: What is the significance of the pitch difference?

A: Pitch defines the center-to-center spacing between adjacent contact positions. The TX25-80P-LT-H1E uses a larger pitch (0.050"), resulting in a wider connector footprint. This difference affects PCB routing density and mechanical fit.

Q: Does the TX25-80P-LT-H1E provide equivalent electrical performance?

A: Both connectors feature gold-plated contacts and support 80-position configurations. The TX25-80P-LT-H1E specifies a defined gold thickness (4.00µin), whereas the original part specifies flash plating. Both maintain MSL 1 environmental classification.

Q: What is the impact of the missing solder retention feature?

A: The PK10M-080P-TH4-DA includes solder retention; the TX25-80P-LT-H1E includes board lock only. Solder retention prevents contact displacement during wave soldering. Applications using selective or reflow soldering may not require this feature.

Q: Is the TX25-80P-LT-H1E RoHS compliant?

A: Yes, the TX25-80P-LT-H1E is ROHS3 compliant. RoHS compliance status for the original PK10M-080P-TH4-DA is not specified in available documentation.
