Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51730-006 is based on strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins and blades, blade power configuration
• Position Count & Layout: 45 total positions with 32 signal and 13 power arrangement
• Pitch & Row Configuration: 0.100" (2.54mm) pitch with 4-row layout
• Mounting & Termination: Board edge, through-hole, right-angle mounting with solder termination
• Environmental & Compliance Ratings: UL94 V-0 flammability, -20°C to 105°C operating range, MSL 1

The substitute part 51720-10703206AALF maintains full electrical and mechanical compatibility with the 51730-006 across all specified parameters. The primary distinction is product status: the 51730-006 is obsolete, while the 51720-10703206AALF is active production with current availability and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 51720-10703206AALF is the direct substitute for the obsolete 51730-006. Both parts are manufactured by Amphenol ICC and maintain identical electrical and mechanical specifications across all critical parameters.

Selection of the 51720-10703206AALF is supported by the following factors:

• Product Status: Active production status ensures ongoing availability and supply chain continuity
• Compliance Enhancement: RoHS compliant status meets current regulatory requirements, whereas the 51730-006 is non-compliant
• REACH Compliance: The substitute part carries REACH Affected designation, addressing environmental and chemical safety requirements
• Functional Equivalence: Identical connector architecture, contact layout, pitch, mounting configuration, and environmental ratings ensure direct compatibility in existing designs
• Packaging: Supplied in tray packaging suitable for automated assembly and inventory management

No design modifications are required when transitioning from the 51730-006 to the 51720-10703206AALF. The parts are mechanically and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 51730-006 and 51720-10703206AALF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (board edge, through-hole, right-angle), pitch (0.100"), position count (45), and row configuration (4 rows). No PCB redesign or mechanical modification is required.

Q: What is the primary reason for substitution?

A: The 51730-006 is obsolete. The 51720-10703206AALF is the active production equivalent, ensuring supply availability and compliance with current regulatory standards.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 51720-10703206AALF is RoHS compliant. The original 51730-006 is RoHS non-compliant. If RoHS compliance is a design requirement, the substitute part satisfies this requirement.

Q: Are the contact specifications identical?

A: Yes. Both parts feature gold or gold GXT™ contact finish with 30.0µin (0.76µm) thickness, identical contact layout (32 signal, 13 power), and equivalent electrical performance across the operating temperature range of -20°C to 105°C.

Q: What is the difference in packaging?

A: The 51720-10703206AALF is supplied in tray packaging, which is standard for high-volume production and automated assembly processes. The original part packaging specification was not provided.

Q: Can I use the 51720-10703206AALF in new designs?

A: Yes. The substitute part is recommended for all new designs requiring a 45-position PwrBlade® backplane connector with the specified electrical and mechanical characteristics. Active production status ensures long-term availability.
