Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS3-2US(01) is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the PS3 series to ensure mechanical and electrical interoperability
• Position Count: Substitute parts must maintain 2-position configuration
• Mounting Configuration: Panel mount requirement must be preserved
• Termination Method: Screw termination must be maintained
• Contact Material & Finish: Gold-plated contacts ensure consistent electrical performance
• Flammability Rating: UL94 V-0 compliance must be retained for safety-critical applications
• Operating Temperature Range: -40°C to 105°C operational envelope must be supported
• Connector Type Variation: While the main part is a Plug, compatible Receptacle variants within the same series may serve complementary functions in backplane applications

The PS3-2US(11) qualifies as a substitute based on shared series designation, position count, panel mount configuration, screw termination, gold contact finish, UL94 V-0 rating, and identical operating temperature range. The primary functional difference is connector type (Receptacle vs. Plug), which is appropriate for backplane connector pairing applications.

Parameter Comparison

Engineering Selection Recommendations

The PS3-2US(11) serves as an active substitute for the PS3-2US(01) based on the following engineering criteria:

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and operate within the identical temperature range of -40°C to 105°C, ensuring compliance with safety and environmental specifications.

Series Continuity: Both connectors belong to the PS3 series, guaranteeing mechanical compatibility and standardized interface dimensions within backplane connector applications.

Product Status Advantage: The PS3-2US(11) maintains Active product status, providing assured long-term availability and supply chain stability, whereas the PS3-2US(01) is designated Last Time Buy with limited remaining inventory.

Functional Pairing: The PS3-2US(11) Receptacle variant is designed to mate with Plug connectors such as the PS3-2US(01), making it suitable for complementary backplane connector configurations where both plug and receptacle positions are required.

Current Rating Consideration: The PS3-2US(11) is rated for 1A current versus the PS3-2US(01) at 150A. Selection must verify that application current requirements do not exceed 1A to ensure safe operation.

Frequently Asked Questions (FAQ)

Q: Can the PS3-2US(11) directly replace the PS3-2US(01) in all applications?

A: The PS3-2US(11) is a functional substitute within the PS3 series for backplane connector applications. However, the current rating difference (1A vs. 150A) requires verification that your application current does not exceed 1A. The connector type difference (Receptacle vs. Plug) means it serves a complementary mating function rather than a direct one-to-one replacement.

Q: What parameters must remain constant when selecting a substitute for PS3-2US(01)?

A: Critical parameters include series designation (PS3), position count (2), mounting type (Panel Mount), termination method (Screw), contact finish (Gold), flammability rating (UL94 V-0), and operating temperature range (-40°C to 105°C). Deviations in these parameters indicate incompatibility.

Q: Why is the PS3-2US(01) marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. This designation signals that existing inventory is limited and no future production runs are planned. Identifying active substitute parts such as the PS3-2US(11) ensures design continuity and supply chain planning.

Q: Are there packaging differences between these parts?

A: The PS3-2US(01) is specified as Bulk packaging with 1119 pieces in stock. The PS3-2US(11) packaging specification is not provided in the available data. Confirm packaging requirements with your supplier before procurement.

Q: What is the significance of the Guide Pin feature listed for PS3-2US(11)?

A: The Guide Pin feature on the PS3-2US(11) Receptacle provides mechanical alignment assistance during mating with compatible Plug connectors, enhancing connection reliability in backplane applications.

Q: How do the voltage ratings compare?

A: The PS3-2US(01) voltage rating is not specified in the available data. The PS3-2US(11) is rated for 1000VAC/DC. Verify voltage requirements for your application against available specifications.
