Amphenol ICC 51915-068 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51915-068 is a 51-position receptacle connector featuring female sockets and blade sockets for board edge, through-hole, right-angle mounting in blade power applications. This connector is part of the PwrBlade® series and is designed for backplane interconnect systems with a contact layout of 48 signal and 3 power positions.

The 51915-068 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where legacy compatibility is required or where active production alternatives are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 51915-068 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle with female sockets and blade sockets
• Position Count: 51 total positions with 47 loaded
• Pitch and Geometry: 0.100" (2.54mm) pitch, 4-row configuration
• Mounting Configuration: Board edge, through-hole, right-angle orientation
• Electrical Characteristics: 48 signal and 3 power contact layout
• Contact Specifications: Gold or Gold GXT™ finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range
• Series Compatibility: PwrBlade® series designation

The substitute part 51915-068LF maintains identical electrical, mechanical, and environmental specifications while differing in product status (active vs. obsolete) and compliance certifications (RoHS compliant vs. non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 51915-068LF is the direct functional equivalent of the 51915-068. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on the following criteria:

For Legacy System Maintenance: The 51915-068 remains available in inventory (956 pcs) and maintains full compatibility with existing designs. This part is appropriate for direct replacement in systems already deployed with the original connector.

For New Designs and Compliance Requirements: The 51915-068LF is the preferred selection. It carries active product status, ensuring long-term availability and supply chain continuity. The 51915-068LF is RoHS compliant and REACH affected, meeting current regulatory requirements for electronic components in most jurisdictions. This part is packaged in trays, supporting standard manufacturing workflows.

Compliance Considerations: The 51915-068 is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the 51915-068LF.

Frequently Asked Questions (FAQ)

Q: Are the 51915-068 and 51915-068LF electrically interchangeable?

A: Yes. Both connectors have identical electrical specifications including contact layout (48 signal, 3 power), contact finish (Gold or Gold GXT™), and operating temperature range (-20°C to 105°C). They are direct electrical equivalents.

Q: Are the 51915-068 and 51915-068LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 51 positions with 47 loaded, 0.100" (2.54mm) pitch, 4-row configuration, board edge through-hole right-angle mounting, and black color. They are direct mechanical equivalents.

Q: What is the difference between these two parts?

A: The primary differences are product status, compliance certifications, and packaging. The 51915-068 is obsolete and RoHS non-compliant, while the 51915-068LF is active, RoHS compliant, and REACH affected. The 51915-068LF is packaged in trays versus bulk packaging for the 51915-068.

Q: Can I use the 51915-068LF as a replacement for the 51915-068 in existing designs?

A: Yes. The 51915-068LF is a direct substitute with identical electrical and mechanical characteristics. No design modifications are required.

Q: Which part should I specify for new designs?

A: Specify the 51915-068LF for new designs. It is the active product with current compliance certifications and ensures supply chain continuity.

Q: What does RoHS compliance mean for this connector?

A: RoHS compliance indicates the connector meets the Restriction of Hazardous Substances directive, limiting the use of specific hazardous materials. The 51915-068LF meets these requirements; the 51915-068 does not.

Q: Are there any performance differences between these connectors?

A: No. Both connectors meet the same UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and operating temperature specifications. Performance is equivalent.
