Amphenol ICC 51752-006 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51752-006 is a 32-position blade power receptacle connector designed for through-hole PCB mounting. This connector features female sockets and blade sockets in a 4-row configuration with 24 signal and 8 power contacts. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

The primary reason for identifying substitute parts is the obsolete status of the 51752-006, which limits long-term availability and supply chain reliability. Active equivalent models ensure continued access to compatible components with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51752-006 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Connector position count (32 positions)
• Row configuration (4 rows)
• Contact pitch (0.100" / 2.54mm)
• Mounting method (through-hole, press-fit termination)
• Contact layout distribution (24 signal, 8 power)
• Contact finish specification (gold plating at 30.0µin thickness)
• Physical color and form factor (black blade power receptacle)
• Operating temperature range (-20°C to 105°C)
• Flammability rating (UL94 V-0)
• Series designation (PwrBlade®)

The 51752-006LF meets all these criteria and is classified as an active product, providing a direct functional and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 51752-006LF is the direct active equivalent for the obsolete 51752-006. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance.

The 51752-006LF offers the following advantages for new designs and ongoing procurement:

• Active product status ensures long-term availability and supply chain continuity
• RoHS compliance meets current environmental and regulatory requirements
• Tray packaging provides improved handling and inventory management compared to bulk packaging
• Identical electrical performance and mechanical compatibility with existing designs

For applications currently using the 51752-006, direct substitution with the 51752-006LF requires no design modifications and maintains full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 51752-006LF be used as a direct replacement for the 51752-006?

A: Yes. The 51752-006LF is a direct equivalent. All electrical and mechanical parameters are identical, including connector type, position count, pitch, mounting method, contact layout, finish specifications, and operating temperature range. No design changes are required.

Q: What is the difference between the 51752-006 and 51752-006LF?

A: The primary differences are product status and regulatory compliance. The 51752-006 is obsolete and RoHS non-compliant, while the 51752-006LF is an active product with RoHS compliance. Packaging differs (bulk versus tray), but electrical and mechanical specifications are identical.

Q: Why is the 51752-006 listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The 51752-006LF represents the active continuation of this product line with improved regulatory compliance.

Q: Are there any compatibility concerns when switching from 51752-006 to 51752-006LF?

A: No compatibility concerns exist. The connectors are mechanically and electrically identical. PCB footprints, mating components, and electrical performance remain unchanged.

Q: What does the "LF" designation in 51752-006LF indicate?

A: The "LF" suffix typically indicates lead-free or RoHS-compliant manufacturing, reflecting current environmental and regulatory standards.

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

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

Q: What packaging options are available?

A: The 51752-006 was supplied in bulk packaging. The 51752-006LF is supplied in tray packaging, which provides better protection and organization for component handling and storage.
