L717DBF25P D-Sub Connector - Equivalent & Substitute Parts

Part Overview

The L717DBF25P is a 25-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins with solder cup termination and is designed for free-hanging, in-line mounting applications. The part is currently active in production status. Identifying equivalent and substitute parts is necessary for design flexibility, supply chain management, and continuity when the primary part becomes unavailable or when alternative sourcing options are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the L717DBF25P is based on the following critical parameters that must be preserved or compatible:

Mandatory Parameters for Substitution:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Number of positions: 25
• Shell size and layout: 3 (DB, B)
• Termination method: Solder cup
• Contact material: Brass or copper alloy

Allowable Variation Parameters:

• Mounting type (free hanging vs. panel mount) may vary depending on application requirements
• Current rating: Substitute must meet or exceed 5A minimum
• Voltage rating: Substitute must meet or exceed specified application voltage
• Operating temperature range: Substitute must encompass or exceed the application requirements
• Contact finish: Gold plating thickness may vary (flash to 30µin acceptable)
• Product status: Active status preferred but obsolete parts acceptable if otherwise compatible

The identified substitutes (172-025-102R001 and DBP25P065TXLF) maintain the core D-Sub 25-pin configuration with solder cup termination while allowing variation in mounting approach, current capacity, and temperature ratings as defined above.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - L717DBF25P: Select the L717DBF25P for applications requiring active production status, standard RoHS compliance, and established supply chain support. This part provides the baseline specifications for free-hanging in-line applications with 7.5A current capacity.

Secondary Selection - DBP25P065TXLF: The DBP25P065TXLF is suitable as a substitute when higher voltage rating (1000V vs. 300V) is required or when advanced gold plating (GXT™) with increased thickness (30.0µin) is beneficial for improved contact durability. This part maintains identical mounting orientation and current rating while providing ROHS3 compliance. Select this part when supply of the primary part is constrained.

Tertiary Selection - 172-025-102R001: The 172-025-102R001 is available as an alternative for panel-mount applications where the connector mounts directly to the chassis. Note that this part carries obsolete product status and has lower current rating (5A vs. 7.5A) and reduced operating temperature range (-50°C ~ 100°C vs. -55°C ~ 125°C). This selection is acceptable only when panel-mount geometry is required and the reduced electrical specifications align with application demands.

Frequently Asked Questions (FAQ)

Q: Can the 172-025-102R001 replace the L717DBF25P in a free-hanging application?

A: No. The 172-025-102R001 is designed for panel-mount configuration, which provides different mechanical mounting geometry than the free-hanging requirement of the L717DBF25P. For free-hanging applications, use L717DBF25P or DBP25P065TXLF.

Q: What is the difference in gold plating between these connectors?

A: The L717DBF25P has 8.00µin (0.203µm) gold plating, the 172-025-102R001 has flash gold plating, and the DBP25P065TXLF has 30.0µin (0.76µm) gold plating with GXT™ enhancement. All finishes are acceptable for signal-level D-Sub applications; thicker plating on the DBP25P065TXLF provides extended contact life under cycling conditions.

Q: Can I use the DBP25P065TXLF in a 300V application?

A: Yes. The DBP25P065TXLF has a voltage rating of 1000V, which exceeds the 300V requirement of the L717DBF25P application. The higher voltage rating is compatible with lower-voltage applications.

Q: Is the 172-025-102R001 acceptable for new designs given its obsolete status?

A: No. For new designs, use L717DBF25P (active) or DBP25P065TXLF (active). The 172-025-102R001 may be used only in legacy design support or when inventory constraints necessitate usage of remaining stock.

Q: What is the minimum current rating requirement for substitution?

A: The substitute must support at least the current level required by the application circuit. The 172-025-102R001 supports 5A maximum, while L717DBF25P and DBP25P065TXLF both support 7.5A. If the application requires greater than 5A, the 172-025-102R001 is not suitable.

Q: Are there temperature range limitations with the 172-025-102R001?

A: Yes. The 172-025-102R001 operates from -50°C to 100°C, which is narrower than both the L717DBF25P (-55°C ~ 125°C) and DBP25P065TXLF (-55°C ~ 125°C). Applications requiring full -55°C to 125°C range cannot use the 172-025-102R001.
