Amphenol ICC 51772-006 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51772-006 is a 34-position receptacle connector featuring female sockets and blade sockets, designed for board edge, through-hole, right-angle mounting in blade power applications. This connector is part of the PwrBlade® series and provides a contact layout of 24 signal and 11 power positions with gold-plated contacts rated for -20°C to 105°C operation.

The 51772-006 carries an obsolete product status, making identification of active equivalent parts essential for new designs and ongoing production support. The substitute part 51772-006LF maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The 51772-006LF qualifies as a direct substitute for the 51772-006 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets and Blade Sockets
• Number of positions: 34
• Pitch: 0.100" (2.54mm)
• Number of rows: 4
• Mounting type: Board Edge, Through Hole, Right Angle
• Termination method: Solder
• Contact layout: 24 Signal, 11 Power
• Contact finish: Gold or Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Color: Black
• Material flammability rating: UL94 V-0
• Operating temperature range: -20°C to 105°C
• Moisture sensitivity level: 1 (Unlimited)

The 51772-006LF maintains complete electrical and mechanical compatibility with the obsolete 51772-006, differing only in product status (Active vs. Obsolete), packaging format (Tray vs. standard), and compliance certifications (RoHS Compliant and REACH Affected status).

Parameter Comparison

Engineering Selection Recommendations

The 51772-006LF is the appropriate selection for new designs and production applications requiring the PwrBlade® 34-position blade power connector. The substitute part provides:

Active Product Status: The 51772-006LF maintains active product status with Amphenol ICC, ensuring continued manufacturing support, availability, and technical documentation access.

Compliance Certifications: The 51772-006LF is RoHS Compliant and REACH Affected, meeting current regulatory requirements for electronic component procurement in regulated markets. The original 51772-006 carries RoHS non-compliant status, which may restrict its use in new designs subject to RoHS directives.

Electrical and Mechanical Equivalence: All functional parameters remain identical between the two parts, including connector type, position count, pitch, mounting configuration, contact layout, and operating temperature range. Direct substitution is supported without design modification.

Packaging Consideration: The 51772-006LF is supplied in Tray packaging, which may differ from the original part's standard packaging. Verify packaging compatibility with receiving and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 51772-006LF be used as a direct replacement for the 51772-006 in existing designs?

A: Yes. The 51772-006LF maintains identical electrical and mechanical specifications, including connector type, 34-position count, 0.100" pitch, board edge through-hole right-angle mounting, solder termination, 24 signal and 11 power contact layout, gold contact finish, and -20°C to 105°C operating temperature range. No design modification is required.

Q: What is the primary difference between these two parts?

A: The 51772-006 is obsolete, while the 51772-006LF is active. Additionally, the 51772-006LF is RoHS Compliant and REACH Affected, whereas the 51772-006 is RoHS non-compliant. Packaging differs, with the 51772-006LF supplied in Tray format.

Q: Are there any compatibility concerns with PCB assembly or connector mating?

A: No compatibility concerns exist. Both parts share identical physical dimensions, mounting footprint, contact pitch, and blade socket configuration. Existing PCB designs and mating connectors are fully compatible with the 51772-006LF.

Q: Does the 51772-006LF meet current regulatory requirements?

A: Yes. The 51772-006LF is RoHS Compliant and REACH Affected, meeting current regulatory standards for electronic component procurement in regulated markets.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix typically indicates lead-free or compliance-enhanced variants. In this case, it denotes the RoHS-compliant version of the base 51772 connector series.

Q: Is the contact finish specification identical between both parts?

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