Engineering Selection Recommendations

The 51752-010LF is the direct substitute for the obsolete 51752-010. Both parts are electrically and mechanically identical across all specified parameters, ensuring pin-for-pin and footprint compatibility.

The 51752-010LF offers two significant advantages:

Product Status: The 51752-010LF maintains active product status with ongoing manufacturer support and availability, whereas the 51752-010 is obsolete and subject to supply discontinuation.

Compliance: The 51752-010LF is RoHS Compliant, meeting current environmental and regulatory requirements. The 51752-010 is RoHS non-compliant and may not satisfy procurement or end-use regulations in certain jurisdictions.

For new designs or system refreshes, the 51752-010LF is the appropriate selection. For legacy system maintenance where the original part number is specified, the 51752-010LF provides full functional equivalence with improved compliance and supply chain assurance.

Frequently Asked Questions (FAQ)

Q: Are the 51752-010 and 51752-010LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 94 positions, 0.100" pitch, 4-row configuration, through-hole mounting, and press-fit termination. PCB footprints and mounting hole patterns are identical.

Q: Are the 51752-010 and 51752-010LF electrically interchangeable?

A: Yes. Both connectors have identical electrical specifications: 92 signal and 2 power contact layout, gold or gold GXT™ contact finish at 30.0µin thickness, and identical operating temperature range (-20°C to 105°C).

Q: What is the difference between the 51752-010 and 51752-010LF?

A: The primary differences are product status and RoHS compliance. The 51752-010LF is an active product with RoHS Compliant status, while the 51752-010 is obsolete and RoHS non-compliant. The 51752-010LF is supplied in Tray packaging.

Q: Can I use the 51752-010LF as a direct replacement in existing designs?

A: Yes. The 51752-010LF provides full functional and mechanical equivalence. No design modifications are required for substitution.

Q: Why is the 51752-010 listed as obsolete?

A: Obsolescence is a manufacturer product lifecycle designation. The 51752-010LF represents the current active equivalent in the PwrBlade® series.

Q: Are there any compatibility considerations with PCB assembly?

A: No. Both connectors use identical press-fit termination and through-hole mounting. Assembly processes and equipment settings remain unchanged.
