DLS3PP5AN23X Equivalent & Substitute Parts

Part Overview

The DLS3PP5AN23X is a 25-position D-Sub stacked plug connector manufactured by Amphenol CONEC, designed for board edge, through-hole, right-angle applications with solder termination. This connector features male pins, gold-plated contacts, and is rated for 7.5A at 125V with an operating temperature range of -55°C to 125°C. The product is actively maintained and ROHS3 compliant. Alternative models are necessary to accommodate different mounting requirements, shell finishes, current ratings, and dielectric materials across various applications and supply chain scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 25-position stacked connectors is determined by compatibility in the following critical parameters:

• Connector Configuration: 25-position, 2-row, D-Sub stacked design with male pins
• Shell Size: 3 (DB, B) dimensional specification
• Termination Method: Solder-based connection
• Contact Type: Signal contacts
• Connector Polarity: Right-angle mounting orientation

The substitute part 178-025-613R571 (NorComp Inc.) qualifies as a functional equivalent based on matching connector type, position count, row configuration, shell size, and termination method. Variations exist in mounting configuration (panel mount vs. board edge), shell finish (nickel vs. tin plated), dielectric material composition, and electrical ratings, which define the scope of acceptable substitution within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The DLS3PP5AN23X offers higher current capacity (7.5A vs. 5A) and extended temperature range to 125°C, making it suitable for higher-power or thermally demanding applications. The 178-025-613R571 is positioned as an alternative for panel-mount applications where board-edge mounting is not required, with availability in larger inventory quantities.

Selection between these parts depends on application-specific electrical requirements, physical mounting constraints, and thermal operating conditions. Both parts are active products with current manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 178-025-613R571 directly replace the DLS3PP5AN23X in all applications? A: Direct substitution requires verification of mounting configuration compatibility. The DLS3PP5AN23X is specified for board-edge, through-hole mounting, while the 178-025-613R571 is configured for panel-mount, through-hole applications. Physical mounting geometry must be confirmed before substitution.

Q: What are the implications of the different current ratings? A: The DLS3PP5AN23X supports 7.5A maximum current, while the 178-025-613R571 is rated for 5A. In applications requiring current draw exceeding 5A, the DLS3PP5AN23X is the appropriate selection. Applications below 5A can utilize either part based on other compatibility criteria.

Q: How do the dielectric materials differ in function? A: The DLS3PP5AN23X uses glass-filled PBT, while the 178-025-613R571 uses nylon 9T polyamide. Both materials provide UL94 V-0 flammability compliance. The different compositions may affect mechanical properties, thermal stability, and environmental resistance depending on specific application exposure conditions.

Q: Are there temperature range considerations for substitution? A: The DLS3PP5AN23X operates to 125°C maximum, while the 178-025-613R571 is specified to 105°C. Applications requiring operation above 105°C must use the DLS3PP5AN23X. Applications within -55°C to 105°C can utilize either part.

Q: What is the significance of the shell finish difference? A: The DLS3PP5AN23X features tin-plated steel, while the 178-025-613R571 is nickel-plated steel. Both finishes provide corrosion protection. Nickel plating may provide enhanced durability in corrosive environments, while tin plating offers advantages in solder compatibility for certain applications.

Q: Are both parts available in tray packaging? A: The DLS3PP5AN23X packaging details are not specified in the provided parameters. The 178-025-613R571 is supplied in tray packaging. Packaging configuration should be verified with the manufacturer or supplier for specific procurement requirements.
