Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFB25P1APN is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Right Angle, Through Hole
• Termination method: Solder
• Shell material and finish: Steel, Tin Plated
• Contact type: Signal
• Flange feature: Housing/Shell (Unthreaded)
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts DB25P564CTXLF and DB25P564GTXLF meet all critical matching parameters. Variations in contact finish specifications (Gold vs. Gold GXT™), contact finish thickness (20.0µin vs. Flash), current ratings (7.5A vs. 5A), backset spacing tolerances (0.406" vs. 0.409"), and packaging format (Tray vs. Bulk) do not preclude substitution when application requirements permit these variations.

Parameter Comparison

Engineering Selection Recommendations

L717DFB25P1APN (Primary Part): This connector is the primary specification and remains the first choice when available. It carries RoHS Compliant status, operates across the full -55°C to 125°C temperature range, and provides a 7.5A current rating per contact. The 20.0µin gold contact finish thickness and brass contact material establish the baseline electrical performance characteristics.

DB25P564GTXLF (Preferred Substitute): This part is the preferred substitute when L717DFB25P1APN is unavailable. It matches all critical mechanical and electrical parameters, including the 300V voltage rating and UL94 V-0 flammability rating. The GXT™ gold finish and copper alloy contact material provide equivalent signal integrity. The 5A per contact current rating is lower than the primary part; applications requiring current levels exceeding 5A per contact must use the primary part. This part is available in bulk packaging and carries 856 units in stock. RoHS Compliant status is confirmed.

DB25P564CTXLF (Secondary Substitute): This part is a secondary substitute option. It meets all critical mechanical parameters and maintains the same operating temperature range and flammability rating. The voltage rating is not specified for this part number, which may present a limitation in applications with defined voltage requirements. The 5A current rating applies. This part is available in tray packaging with 793 units in stock and carries ROHS3 Compliant status.

Selection Criteria:

• For applications requiring 300V voltage rating confirmation: Use L717DFB25P1APN or DB25P564GTXLF
• For applications requiring current levels above 5A per contact: Use L717DFB25P1APN
• For bulk packaging requirements: Use DB25P564GTXLF
• For tray packaging requirements: Use L717DFB25P1APN or DB25P564CTXLF

All three parts satisfy RoHS compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can DB25P564GTXLF be used as a direct replacement for L717DFB25P1APN?

A: DB25P564GTXLF is a functional equivalent when application current requirements do not exceed 5A per contact and when bulk packaging is acceptable. The connector maintains identical mechanical fit, pin configuration, and mounting characteristics. The GXT™ gold finish provides equivalent electrical performance to the standard gold finish of the primary part.

Q: What is the difference between the contact finish specifications?

A: The L717DFB25P1APN specifies 20.0µin (0.51µm) gold plating thickness, while both substitute parts specify flash gold plating with GXT™ technology. Flash plating provides a thinner, more uniform coating optimized for signal integrity in high-frequency applications. Both finishes meet the same electrical performance standards for D-Sub 25-position connectors.

Q: Are there current rating limitations when using substitute parts?

A: Yes. The L717DFB25P1APN is rated for 7.5A per contact, while both DB25P564CTXLF and DB25P564GTXLF are rated for 5A per contact. Applications requiring current levels between 5A and 7.5A per contact must use the primary part number L717DFB25P1APN.

Q: What is the significance of the backset spacing difference?

A: The L717DFB25P1APN specifies 0.406" (10.30mm) backset spacing, while substitute parts specify 0.409" (10.40mm). This 0.003" (0.10mm) difference falls within standard D-Sub connector tolerances and does not affect mechanical compatibility or electrical performance in standard applications.

Q: Does the contact material difference affect performance?

A: The L717DFB25P1APN uses brass contacts, while substitute parts use copper alloy contacts. Both materials provide equivalent electrical conductivity and signal integrity for D-Sub signal applications. The copper alloy contacts in substitute parts are optimized for the GXT™ gold finish technology.

Q: Which substitute part should be selected for new designs?

A: DB25P564GTXLF is the recommended substitute for new designs when the primary part is unavailable. It provides confirmed 300V voltage rating, bulk packaging availability, and RoHS Compliant status. The 5A per contact current rating is suitable for standard D-Sub signal applications.

Q: Are all three parts RoHS compliant?

A: L717DFB25P1APN and DB25P564GTXLF carry RoHS Compliant status. DB25P564CTXLF carries ROHS3 Compliant status. All three parts satisfy RoHS compliance requirements for their respective regulatory frameworks.

Q: What packaging options are available?

A: L717DFB25P1APN is supplied in tray packaging (812 units in stock). DB25P564CTXLF is supplied in tray packaging (793 units in stock). DB25P564GTXLF is supplied in bulk packaging (856 units in stock). Packaging selection depends on assembly process requirements and inventory management practices.

Q: Can these parts be used interchangeably in existing assemblies?

A: Mechanical and electrical interchangeability is confirmed for all three parts in standard D-Sub 25-position applications. The identical connector style, pin configuration, mounting type, and shell size ensure physical fit compatibility. Applications with specific current or voltage requirements must verify that substitute part ratings meet those requirements.
