Amphenol P28964 Circular Connector Distributor T-Shaped

Part Overview

The Amphenol Sine Systems Corp P28964 is an active-status circular connector distributor configured as a T-shaped adapter with four-position connectivity. This component functions as a one-to-two distribution point, converting from 4-position female sockets to dual outputs: 4-position female sockets and 4-position male pins in a free-hanging, in-line mounting configuration. Finding equivalent alternatives is necessary for supply chain flexibility, procurement cost optimization, and regional availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the P28964 is determined by equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Connector style: Distributor T-shaped configuration
• Contact positions: 4-position input and 4-position dual outputs (2 x 4-position)
• Connector type conversion: Female sockets input with female sockets and male pins outputs
• Mounting configuration: Free-hanging, in-line orientation
• Fastening mechanism: Threaded coupling nut
• Ingress protection rating: IP67 or higher
• Voltage rating: 600VAC/DC minimum
• Orientation: Keyed
• RoHS compliance: ROHS3 minimum

Acceptable Parameter Variance:

• Shell size: Different metric or imperial equivalent designations acceptable if physical and electrical compatibility is maintained
• Housing material: Thermoplastic or Thermoplastic Elastomer (TPE) acceptable
• Current rating: Equal to or greater than 25A
• Operating temperature: Ranges that encompass or extend the -40°C to 90°C specification
• Shielding: Unshielded configurations only

Parameter Comparison

Engineering Selection Recommendations

The Molex 1300680099 from the Brad Quick-Change 130068 series functions as a direct substitute for the Amphenol P28964. Both components maintain active product status and ROHS3 compliance, meeting regulatory and environmental requirements for circular connector distributor applications.

The 1300680099 exceeds the P28964 specification in two measurable parameters: current rating (32A versus 25A) and operating temperature upper limit (105°C versus 90°C). These performance enhancements provide additional headroom in thermal and electrical stress scenarios without requiring design modification.

The primary material variation—Thermoplastic Elastomer (TPE) versus Thermoplastic—represents a material property difference in housing composition. Both housing materials are thermally classified to the required UL94 V-0 or equivalent flammability standard and function identically in the specified application envelope.

Selection between these parts depends on supply availability, cost considerations, and application-specific thermal or electrical stress margins.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1300680099 directly replace the Amphenol P28964 in my current design? A: Yes. The 1300680099 meets all mandatory equivalence parameters: identical T-shaped distributor configuration, 4-position connectivity, female-to-female/male contact arrangement, free-hanging in-line mounting, threaded fastening, IP67 ingress protection, 600VAC/DC voltage rating, keyed orientation, and ROHS3 compliance.

Q: What are the differences between shell sizes M35 and 1 3/8"? A: M35 denotes metric designation (35mm); 1 3/8" is the imperial equivalent measurement. Both designations reference physically and electrically compatible connector sizes suitable for 4-position circular connector contacts.

Q: Does the higher current rating of the 1300680099 (32A) affect compatibility? A: No. A higher current rating indicates enhanced electrical capacity. If your circuit operates at or below 25A, the 1300680099 operates safely with additional margin. Design modifications are not required.

Q: Can I use the 1300680099 in temperature environments outside the P28964 specification? A: The 1300680099 operating range of -20°C to 105°C extends above the P28964 limit of 90°C. If your application operates above 90°C, the 1300680099 provides rated protection. Both parts function identically within the -40°C to 90°C common envelope.

Q: Are housing material differences (Thermoplastic versus TPE) functionally significant? A: Both materials meet UL94 V-0 flammability requirements and perform identically in electrical and mechanical applications. TPE (Thermoplastic Elastomer) provides increased elasticity; Thermoplastic provides standard rigidity. Material selection does not affect substitution compatibility.

Q: What is the difference between the PowerBOSSlite™ M35 and Brad Quick-Change 130068 series? A: These are manufacturer-specific product line designations. Both series produce functionally equivalent T-shaped 4-position distributor connectors with matched electrical and mechanical specifications suitable for identical applications.
