PK10M-080P-TH2-DA Equivalent & Substitute Parts

Part Overview

The PK10M-080P-TH2-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 equivalent substitute parts essential for ongoing system maintenance 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 support without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PK10M-080P-TH2-DA is determined by the following critical parameters:

• Connector Type: Must be Plug with Center Strip Contacts
• Number of Positions: Must be 80
• Number of Rows: Must be 2
• Mounting Type: Must be Through Hole, Right Angle
• Contact Finish: Must be Gold
• Pitch Tolerance: Acceptable variance within connector family specifications
• Height Above Board: Acceptable variance within standard PCB clearance tolerances
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The TX25-80P-LT-H1E meets these substitution criteria. While the pitch specification differs (0.050" versus 0.039"), both connectors maintain the same 80-position, 2-row configuration with identical connector type, mounting orientation, and contact finish. The height above board variance (0.354" versus 0.343") falls within acceptable mechanical tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The TX25-80P-LT-H1E is the qualified substitute for the obsolete PK10M-080P-TH2-DA based on the following factors:

Product Status: The TX25-80P-LT-H1E maintains active production status with 1621 units in current inventory, ensuring long-term availability compared to the obsolete original component.

Compliance: The TX25-80P-LT-H1E is ROHS3 compliant, meeting current regulatory requirements for electronic component procurement. Both parts share identical MSL 1 classification and ECCN/HTSUS codes.

Electrical and Mechanical Compatibility: Both connectors maintain 80-position, 2-row configuration with gold-plated center strip contacts and through-hole right-angle mounting. The pitch and height variations are within acceptable tolerances for standard PCB applications.

Feature Alignment: Both connectors include board lock features. The original component includes solder retention; this feature is not specified for the substitute.

Frequently Asked Questions (FAQ)

Q: Can the TX25-80P-LT-H1E directly replace the PK10M-080P-TH2-DA without PCB modification?

A: The TX25-80P-LT-H1E is mechanically and electrically compatible for most applications. The pitch difference (0.050" versus 0.039") and height variance (0.354" versus 0.343") are within standard tolerances. PCB layout verification is required to confirm clearance and contact alignment for your specific application.

Q: What is the significance of the pitch difference between these connectors?

A: Pitch refers to the center-to-center distance between adjacent contact positions. The 0.050" pitch of the TX25-80P-LT-H1E versus the 0.039" pitch of the original component affects PCB footprint spacing. Both maintain the same 80-position, 2-row configuration but with different overall connector width.

Q: Does the TX25-80P-LT-H1E include solder retention like the original part?

A: The original PK10M-080P-TH2-DA specifies solder retention as a feature. The TX25-80P-LT-H1E specification does not include this feature. Verify solder retention requirements for your application before final component selection.

Q: Are both connectors moisture sensitive?

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply.

Q: What is the inventory status for the substitute part?

A: The TX25-80P-LT-H1E has 1621 units in current stock, providing immediate availability for procurement compared to the obsolete original component.
