Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L717DB25PAM4B are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Number of positions: 25
• Number of rows: 2
• Shell size/layout: 3 (DB, B)
• Mounting type: Through hole, right angle
• Termination: Solder
• Shell material/finish: Steel, tin plated
• Flange feature: Housing/shell (unthreaded)
• Contact type: Signal
• Dielectric material: Thermoplastic
• Operating temperature range: -55°C to 125°C
• Compliance: RoHS compliant, REACH unaffected, EAR99 classification

Allowable Variations: Substitute parts may differ in contact material composition (brass versus copper alloy), contact finish thickness specification (measured versus flash), backset spacing tolerance, current rating per contact, and packaging format (tray versus bulk), provided all mandatory parameters remain equivalent and electrical performance remains within specified ratings.

Parameter Comparison

Engineering Selection Recommendations

L717DB25PAM4B (Primary Part): This connector is the primary selection for applications requiring the specified 7.5A current rating and 0.590" backset spacing. The part maintains active product status with RoHS compliance and carries full voltage rating specification of 300V. The brass contact material with 8.00µin gold plating provides the specified contact finish thickness. This part is suitable for standard D-Sub 25 position applications with through-hole right angle solder termination.

DB25P564GTXLF (Preferred Substitute): This substitute part is functionally equivalent for applications where the 5A per contact current rating is acceptable. The part maintains identical shell size, mounting configuration, and termination method. The GXT™ gold finish with flash thickness specification provides equivalent contact performance. The 300V voltage rating matches the primary part. RoHS compliance is confirmed. The Board Lock feature provides enhanced mechanical retention. This part is suitable where the lower current rating and alternative backset spacing (0.409") are compatible with circuit board layout requirements.

DB25P564CTXLF (Secondary Substitute): This substitute part provides functional equivalence for applications where the 5A current rating is acceptable and voltage rating specification is not critical. The GXT™ gold finish provides equivalent contact performance to the primary part. ROHS3 compliance is confirmed. The 0.409" backset spacing differs from the primary part and requires verification of circuit board layout compatibility. This part is suitable for applications where the lower current rating and alternative backset spacing are compatible with design requirements.

Frequently Asked Questions (FAQ)

Q: Can DB25P564GTXLF and DB25P564CTXLF be used interchangeably with L717DB25PAM4B?

A: Both substitute parts share identical connector type, position count, shell size, mounting configuration, and termination method. However, the current rating differs (5A versus 7.5A), and backset spacing differs (0.409" versus 0.590"). Substitution is valid only when the application current requirements do not exceed 5A per contact and the circuit board layout accommodates the alternative backset spacing.

Q: What is the difference between DB25P564GTXLF and DB25P564CTXLF?

A: Both parts use identical connector specifications and GXT™ gold contact finish. The primary differences are packaging format (DB25P564GTXLF is bulk; DB25P564CTXLF is tray) and voltage rating specification (DB25P564GTXLF specifies 300V; DB25P564CTXLF does not specify voltage rating). For applications requiring 300V rating confirmation, DB25P564GTXLF is the appropriate selection.

Q: Does backset spacing affect connector compatibility?

A: Backset spacing (0.590" for L717DB25PAM4B versus 0.409" for both substitute parts) determines the distance from the connector mounting surface to the contact insertion point. This parameter directly affects circuit board layout and component placement. Substitution requires verification that the alternative backset spacing is compatible with the target application's printed circuit board design.

Q: Are the substitute parts RoHS compliant?

A: Yes. L717DB25PAM4B is RoHS Compliant. DB25P564GTXLF is RoHS Compliant. DB25P564CTXLF is ROHS3 Compliant. All parts meet RoHS requirements and are REACH unaffected.

Q: What is the significance of the GXT™ finish on substitute parts?

A: GXT™ is a proprietary gold plating technology applied as a flash thickness. This finish provides equivalent contact performance to the 8.00µin (0.203µm) gold plating on the primary part. Both finishes deliver the required electrical conductivity and corrosion resistance for signal applications.

Q: Can I substitute based on current rating alone?

A: No. Current rating is one of multiple critical parameters. Substitution requires equivalence across connector type, position count, shell size, mounting configuration, termination method, shell material, and operating temperature range. The lower current rating of substitute parts (5A) is acceptable only when the application design does not require the 7.5A rating of the primary part.

Q: What compliance certifications apply to all three parts?

A: All three parts are UL94 V-0 flammable, EAR99 classified, and REACH unaffected. Operating temperature range is -55°C to 125°C for all parts. All parts are classified under HTSUS 8536.69.4040.
