Key Parameters

Substitute Part Grouping Explanation

Substitution of the 72902-264LF is determined by the following critical parameters that must align between the original and substitute component:

Primary Matching Criteria:

• Connector type: Receptacle with female sockets
• Number of positions: 96
• Pitch: 0.100" (2.54mm)
• Number of rows: 3
• Mounting type: Through hole
• Contact finish: Gold or gold-based plating
• Insulation material: PBT or compatible polymer

Secondary Compatibility Factors:

• Termination method compatibility with PCB assembly processes
• Moisture sensitivity level
• Regulatory compliance (REACH, ECCN classification)

The substitute part 1-1393642-6 meets all primary matching criteria and maintains compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1-1393642-6 substitute part is suitable for applications requiring replacement of the obsolete 72902-264LF based on the following factors:

Mechanical Compatibility: Both connectors share identical pitch (0.100"), position count (96), row configuration (3), and through-hole mounting architecture, ensuring direct physical compatibility with existing PCB layouts.

Electrical Compatibility: Both components feature gold-based contact finishes and PBT insulation materials, maintaining signal integrity and environmental protection equivalent to the original design.

Product Status Advantage: The substitute part carries active product status with ROHS3 compliance and UL94 V-0 flammability rating, providing enhanced regulatory alignment for new designs and long-term availability assurance.

Termination Consideration: The substitute employs wire wrap termination versus the original solder termination. Assembly process compatibility must be evaluated based on specific manufacturing capabilities and design requirements.

Temperature and Compliance: The substitute specifies an operating temperature range of -55°C to 125°C and includes formal flammability certification, providing documented performance parameters absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 1-1393642-6 be used as a direct replacement for the 72902-264LF in existing assemblies?

A: Physical and electrical compatibility is confirmed through matching connector geometry, position count, pitch, and contact finish specifications. However, termination method differences (wire wrap versus solder) require assessment of assembly process compatibility and PCB design implementation.

Q: What is the significance of "Number of Positions Loaded" differing between the two parts?

A: The original part has 48 positions loaded while the substitute has all 96 positions loaded. This indicates the substitute provides full position availability. Compatibility depends on whether the application utilizes only the 48 loaded positions or requires the additional capacity.

Q: Does the substitute part meet current regulatory requirements?

A: The 1-1393642-6 carries ROHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory standards. The original 72902-264LF does not specify these certifications, making the substitute advantageous for applications requiring documented compliance.

Q: Are there differences in contact finish specifications?

A: The original specifies gold plating at 78.7µin (2.00µm) thickness. The substitute specifies gold or gold-palladium finish without thickness specification. Both finishes provide equivalent corrosion resistance and signal integrity for backplane connector applications.

Q: What is the impact of different insulation materials?

A: Both parts use PBT as the primary insulation material. The substitute additionally specifies glass-filled polyester, which enhances mechanical strength and thermal stability. This represents an improvement over the original specification.

Q: How does the operating temperature specification affect substitution?

A: The substitute specifies -55°C to 125°C operating range while the original does not specify temperature limits. For applications operating within this range, the substitute provides documented thermal performance. Applications requiring operation outside this range require specific evaluation.
