Amphenol ICC 51915-064 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51915-064 is a 30-position receptacle connector featuring female sockets and blade sockets, designed for board edge, through-hole, right-angle mounting applications. This connector is part of the PwrBlade® series and provides a contact layout of 24 signal and 6 power positions with gold-plated contacts and guide pin features.

The 51915-064 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this connector specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51915-064 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Position count: 30 positions
• Pitch specification: 0.100" (2.54mm)
• Row configuration: 4 rows
• Mounting method: Board edge, through-hole, right-angle orientation
• Termination method: Solder
• Contact layout distribution: 24 signal, 6 power
• Contact finish specification: Gold or Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Housing color: Black
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C ~ 105°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 51915-064LF meets all these parameters and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 51915-064LF is the direct substitute for the obsolete 51915-064. Both parts share identical electrical and mechanical specifications across all critical parameters that determine connector functionality and compatibility.

The primary distinction between these parts is product status and regulatory compliance. The 51915-064LF carries active product status, ensuring ongoing manufacturer support and availability. Additionally, the 51915-064LF is RoHS compliant, whereas the 51915-064 is RoHS non-compliant. The 51915-064LF also carries REACH affected status.

For new designs and ongoing applications, the 51915-064LF is the appropriate selection. The packaging difference (tray versus bulk) reflects standard distribution practices and does not affect connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 51915-064 and 51915-064LF electrically and mechanically interchangeable?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, mounting method, termination, contact layout, contact finish, flammability rating, and operating temperature range. They are direct functional equivalents.

Q: What is the significance of the "LF" designation in the 51915-064LF part number?

A: The "LF" suffix indicates lead-free compliance. The 51915-064LF is RoHS compliant, whereas the 51915-064 is not. This reflects the shift toward lead-free manufacturing standards in the electronics industry.

Q: Why is the 51915-064 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The 51915-064LF represents the current active equivalent and is the recommended selection for all applications.

Q: Does the packaging difference (tray versus bulk) affect connector performance?

A: No. Packaging is a distribution and handling consideration only. It does not affect the electrical or mechanical performance of the connector itself.

Q: Can the 51915-064LF be used as a direct replacement in existing assemblies designed for the 51915-064?

A: Yes. The identical specifications across all functional parameters ensure direct compatibility. No design modifications are required.

Q: What is the contact finish thickness specification?

A: Both connectors feature a contact finish thickness of 30.0µin (0.76µm), which is consistent with the gold or gold GXT™ finish specification.
