Key Parameters

Substitute Part Grouping Explanation

The 51752-012LF qualifies as a direct substitute based on identical electrical and mechanical parameters across all critical substitution criteria:

Matching Parameters:

• Connector type, style, and configuration (43-position receptacle, female sockets and blade sockets)
• Pitch and row configuration (0.100" / 2.54mm, 4 rows)
• Mounting method and termination technology (through-hole, press-fit)
• Contact layout distribution (32 signal, 11 power)
• Contact finish specification and thickness (Gold or Gold, GXT™, 30.0µin)
• Physical housing color (black)
• Operating temperature range (-20°C ~ 105°C)
• Flammability and moisture sensitivity ratings (UL94 V-0, MSL 1)

The primary distinction is product status: 51752-012 is obsolete, while 51752-012LF is active production with enhanced compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 51752-012LF is the direct functional equivalent for applications currently using the 51752-012. Selection of the substitute part is based on the following engineering factors:

Product Status: The 51752-012 is obsolete and no longer in active production. The 51752-012LF maintains identical electrical and mechanical specifications while remaining in active production status, ensuring long-term supply chain availability.

Compliance Status: The 51752-012LF provides enhanced regulatory compliance with RoHS certification and REACH compliance status, addressing modern environmental and regulatory requirements. The original 51752-012 is RoHS non-compliant.

Electrical and Mechanical Compatibility: All critical parameters—connector configuration, pitch, mounting method, contact layout, and operating specifications—are identical between the two parts, ensuring direct functional interchangeability in PCB designs.

Packaging: The 51752-012LF is supplied in tray packaging, which is standard for production environments and supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 51752-012LF be used as a direct replacement for the 51752-012 in existing designs?

A: Yes. The 51752-012LF is electrically and mechanically identical to the 51752-012 across all specified parameters, including connector type, position count, pitch, mounting method, contact layout, and operating temperature range. No design modifications are required.

Q: What is the primary reason for substituting the 51752-012 with the 51752-012LF?

A: The 51752-012 is obsolete and no longer manufactured. The 51752-012LF is the active production equivalent that maintains identical specifications while ensuring continued supply availability.

Q: Are there compliance differences between these parts?

A: Yes. The 51752-012LF is RoHS compliant and REACH affected, while the 51752-012 is RoHS non-compliant. For applications subject to environmental regulations or customer requirements, the 51752-012LF is the appropriate selection.

Q: Do these connectors have the same contact finish specifications?

A: Yes. Both parts feature gold or gold GXT™ contact finish with 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and reliability.

Q: What is the pitch and row configuration for these connectors?

A: Both connectors have a 0.100" (2.54mm) pitch with 4 rows, accommodating 43 total positions distributed as 32 signal and 11 power contacts.

Q: Are there packaging considerations when switching to the 51752-012LF?

A: The 51752-012LF is supplied in tray packaging, which is standard for production environments. Verify that your procurement and assembly processes support tray packaging format.

Q: What is the operating temperature range for these connectors?

A: Both the 51752-012 and 51752-012LF operate across -20°C to 105°C, supporting standard industrial and commercial temperature environments.
