Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PK10M-050PP-THR-DA is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the Pak 10 (PK10M) series to ensure mechanical and electrical interchangeability
• Position Count: 50-position configuration must be maintained
• Pitch Specification: 0.039" (1.00mm) pitch is mandatory for contact alignment
• Row Configuration: 2-row arrangement must be preserved
• Connector Type: Center strip contact design must remain consistent
• Orientation: Right-angle mounting orientation is required
• Contact Finish: Gold plating with flash thickness ensures equivalent electrical performance
• Moisture Sensitivity: MSL 1 rating provides equivalent environmental reliability

The primary distinction between the main part and substitute relates to mounting technology: the main part uses through-hole mounting, while the substitute employs surface-mount technology. This difference affects board integration methodology but does not alter electrical or mechanical compatibility within the PK10M series framework.

Parameter Comparison

Engineering Selection Recommendations

The PK10M-050PP-SMR-DA serves as the active-status equivalent within the PK10M series. Selection between through-hole and surface-mount variants depends on board design requirements:

Through-Hole Mounting (PK10M-050PP-THR-DA): Suitable for applications requiring mechanical robustness and rework capability. This part is obsolete and procurement may face supply constraints.

Surface-Mount Mounting (PK10M-050PP-SMR-DA): Recommended for new designs and ongoing production. This part maintains active product status, ensuring continued availability. The substitute carries RoHS compliance certification, meeting current regulatory requirements. Height above board differs by 0.016" (0.40mm), which may require PCB layout adjustment.

Both variants maintain identical electrical specifications, contact configuration, and environmental ratings within the PK10M series framework.

Frequently Asked Questions (FAQ)

Q: Can the PK10M-050PP-SMR-DA directly replace the PK10M-050PP-THR-DA?

A: Electrical and mechanical compatibility is maintained across all critical parameters: position count, pitch, row configuration, connector type, orientation, and contact finish. The primary difference is mounting technology (surface mount versus through hole), which requires corresponding PCB design modifications.

Q: What is the significance of the product status difference?

A: The main part is classified as obsolete, indicating discontinued manufacturing. The substitute maintains active product status, ensuring ongoing availability and supply chain reliability for new procurements and production runs.

Q: Are there compliance differences between these parts?

A: The substitute part carries RoHS compliance and REACH unaffected status certifications. The main part specifications do not include these compliance designations. Both parts maintain MSL 1 rating and identical ECCN and HTSUS classifications.

Q: How does the height above board difference affect selection?

A: The substitute is 0.016" (0.40mm) lower than the main part. This dimensional variance requires PCB layout verification to ensure clearance compatibility with mating connectors and surrounding components.

Q: Are both parts within the same connector series?

A: Both parts belong to the Pak 10 (PK10M) series, ensuring mechanical and electrical interchangeability within the series framework. The base product number PK10M is identical for both variants.
