Amphenol ICC 51915-072 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51915-072 is a 20-position blade power receptacle connector designed for board edge, through-hole mounting applications. This connector features female sockets and blade sockets in a right-angle configuration with black housing. The part is classified as obsolete, making identification of suitable alternatives essential for ongoing system support and new design implementations.

The 51915-072 serves applications requiring reliable power distribution and signal connectivity in backplane environments, with a contact layout of 12 signal and 8 power positions. Due to its obsolete status, sourcing equivalent or substitute components is necessary for procurement and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 51915-072 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Number of positions: 20
• Pitch: 0.100" (2.54mm)
• Number of rows: 4
• Mounting configuration: Board edge, through-hole, right-angle
• Termination method: Solder
• Contact layout: 12 signal, 8 power positions
• Contact finish: Gold or Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Housing color: Black
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C to 105°C
• Features: Board lock and guide pin

The substitute part 51915-072LF meets all these criteria and is manufactured by the same supplier within the same PwrBlade® series.

Parameter Comparison

Engineering Selection Recommendations

The 51915-072LF is a direct functional equivalent to the 51915-072 across all electrical and mechanical parameters. The primary distinctions are:

Product Status: The 51915-072LF carries an active product status, ensuring ongoing manufacturer support and availability, whereas the 51915-072 is obsolete.

Compliance: The 51915-072LF is RoHS compliant and REACH affected, providing compliance with current environmental regulations. The 51915-072 is RoHS non-compliant.

Packaging: The 51915-072LF is supplied in tray packaging, which is standard for active production components.

For new designs and ongoing procurement, the 51915-072LF is the appropriate selection. For legacy system maintenance where the original 51915-072 specification is required, the 51915-072LF provides full functional compatibility with improved regulatory compliance.
