Key Parameters

Substitute Part Grouping Explanation

Substitution of the PK10M-080P-TH3-DA is based on the following critical parameters:

• Connector Type & Position Count: Both the main part and substitute maintain 80-position plug configuration with center strip contacts
• Mounting Configuration: Through-hole, right-angle orientation is preserved
• Contact Material & Finish: Gold plating is maintained across all substitute options
• Row Configuration: 2-row arrangement is consistent
• Moisture Sensitivity: MSL 1 rating is maintained, indicating unlimited shelf life

The substitute part TX25-80P-LT-H1E from JAE Electronics meets these core substitution criteria. Variations in pitch (0.050" vs. 0.039") and height above board (0.354" vs. 0.382") represent design trade-offs that must be evaluated within specific application constraints.

Engineering Selection Recommendations

The TX25-80P-LT-H1E represents the primary substitute for the obsolete PK10M-080P-TH3-DA. Selection between these components should be based on the following factors:

Product Status: The PK10M-080P-TH3-DA is obsolete, whereas TX25-80P-LT-H1E maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: TX25-80P-LT-H1E carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic components in regulated markets.

Physical Dimensions: The pitch difference (0.039" vs. 0.050") and height variation (0.382" vs. 0.354") require PCB layout verification to confirm mechanical compatibility within the target application's spatial constraints.

Contact Finish Specification: TX25-80P-LT-H1E provides a defined contact finish thickness of 4.00µin, whereas the original part specifies flash plating. This difference may impact contact resistance characteristics and long-term reliability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Can TX25-80P-LT-H1E be used as a direct replacement for PK10M-080P-TH3-DA?

A: TX25-80P-LT-H1E shares the same connector type, position count, row configuration, mounting style, and contact material. However, the pitch difference (0.050" vs. 0.039") and height above board variation (0.354" vs. 0.382") require PCB layout verification. Direct substitution is possible only if the target PCB accommodates these dimensional changes.

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

A: Pitch determines the spacing between contact positions on the connector. The 0.050" pitch of TX25-80P-LT-H1E is coarser than the 0.039" pitch of the original part. This affects PCB trace routing, contact density, and overall connector footprint. PCB redesign may be necessary for substitution.

Q: Does the contact finish thickness difference affect performance?

A: The original part specifies flash plating, while TX25-80P-LT-H1E provides 4.00µin (0.100µm) thickness. Thicker plating generally provides improved durability in high-cycle mating environments and enhanced corrosion resistance. Flash plating is thinner and suitable for lower-cycle applications.

Q: Is ROHS3 compliance a requirement for this substitution?

A: ROHS3 compliance is mandatory in many regulated markets and industries. TX25-80P-LT-H1E meets this requirement, whereas the original part does not specify compliance status. Verify regulatory requirements for your specific application and market.

Q: What inventory considerations should be evaluated?

A: TX25-80P-LT-H1E has higher current inventory availability (1621 pcs vs. 721 pcs), supporting longer-term supply chain stability. The original part's obsolete status limits future availability.
