Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the L77DB25P1AMN is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: D-Sub Plug with Male Pins
• Position count: 25 positions
• Row configuration: 2 rows
• Shell size: 3 (DB, B)
• Mounting style: Through Hole, Right Angle
• Termination: Solder
• Flange feature: Housing/Shell (Unthreaded)
• Operating temperature range: -55°C to 125°C
• Connector style: D-Sub
• Series: D

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional equivalence:

• Contact material composition (Brass versus Copper Alloy)
• Contact finish thickness specification (8.00µin versus Flash)
• Current rating per contact (7.5A versus 5A per contact)
• Backset spacing tolerance (0.406" versus 0.409")
• Packaging format (Tray, Bulk, or standard)
• Specific manufacturer division (Commercial Products versus FCI)
• Additional features (Board Lock, Mounting Brackets)
• Voltage rating specification (300V stated versus not specified)

The substitute parts DB25P564CTXLF and DB25P564GTXLF meet all mandatory matching criteria and are therefore electrically and mechanically interchangeable with the L77DB25P1AMN in standard D-Sub connector applications.

Parameter Comparison

Engineering Selection Recommendations

L77DB25P1AMN Selection Criteria: The L77DB25P1AMN is suitable for applications requiring the specified 7.5A current rating per contact and explicit 300V voltage rating. This part carries full RoHS compliance and includes both grounding indents and mounting brackets as standard features. Select this part when the higher current capacity and integrated mounting bracket features are required for the application.

DB25P564CTXLF Selection Criteria: The DB25P564CTXLF is suitable for applications where the 5A per contact current rating is sufficient and packaging in tray format is preferred for automated assembly processes. This part carries ROHS3 compliance and includes grounding indents. The voltage rating is not specified for this variant. Select this part when tray packaging and ROHS3 compliance are procurement requirements.

DB25P564GTXLF Selection Criteria: The DB25P564GTXLF is suitable for applications requiring the 5A per contact current rating with explicit 300V voltage rating specification. This part carries full RoHS compliance and includes both board lock and grounding indents features. Bulk packaging format is standard for this variant. Select this part when board lock retention feature and bulk packaging are required for the application.

Compliance Considerations: All three parts maintain UL94 V-0 flammability rating, unlimited moisture sensitivity level (MSL 1), and operating temperature range of -55°C to 125°C. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040. The L77DB25P1AMN and DB25P564GTXLF both specify 300V voltage rating, while DB25P564CTXLF does not specify this parameter.

Frequently Asked Questions (FAQ)

Q: Can DB25P564CTXLF or DB25P564GTXLF be used as direct replacements for L77DB25P1AMN in existing designs?

A: Yes, both substitute parts are mechanically and electrically compatible with the L77DB25P1AMN. All three connectors share identical connector type, position count, row configuration, shell size, mounting style, and termination method. The substitute parts maintain the same operating temperature range and flammability rating. Verify that the application current requirements do not exceed 5A per contact, as the substitute parts are rated at 5A compared to the L77DB25P1AMN at 7.5A.

Q: What is the difference between the two substitute parts, DB25P564CTXLF and DB25P564GTXLF?

A: Both parts share the same base part number (DB25P564) and are functionally equivalent. The primary differences are packaging format (Tray for DB25P564CTXLF versus Bulk for DB25P564GTXLF), voltage rating specification (not specified for DB25P564CTXLF versus 300V for DB25P564GTXLF), and additional features (DB25P564GTXLF includes board lock retention feature). Select based on packaging requirements and whether explicit voltage rating specification is needed for documentation.

Q: Are there any current rating limitations when substituting with DB25P564CTXLF or DB25P564GTXLF?

A: Yes. The L77DB25P1AMN is rated at 7.5A per contact, while both substitute parts are rated at 5A per contact. Applications requiring current levels between 5A and 7.5A per contact must use the L77DB25P1AMN. Applications operating at or below 5A per contact can use either substitute part without current rating concerns.

Q: What is the backset spacing difference between the main part and substitutes?

A: The L77DB25P1AMN specifies 0.406" (10.30mm) backset spacing, while both substitute parts specify 0.409" (10.40mm). This 0.003" (0.10mm) difference is within standard D-Sub connector tolerance ranges and does not affect mechanical or electrical compatibility in standard applications.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. The L77DB25P1AMN and DB25P564GTXLF are RoHS Compliant. The DB25P564CTXLF is ROHS3 Compliant. All three parts meet RoHS environmental compliance standards. ROHS3 represents an updated compliance designation and is acceptable for applications requiring RoHS compliance.

Q: What packaging options are available for each part?

A: The L77DB25P1AMN packaging format is not specified in the standard documentation. The DB25P564CTXLF is supplied in Tray packaging, suitable for automated pick-and-place assembly. The DB25P564GTXLF is supplied in Bulk packaging. Select based on assembly process requirements and inventory management preferences.

Q: Are the contact materials different between the main part and substitutes?

A: Yes. The L77DB25P1AMN uses Brass contact material, while both substitute parts use Copper Alloy contact material. Both materials are standard for D-Sub connectors and provide equivalent electrical performance. The contact finish is Gold for all three parts, with the L77DB25P1AMN specifying 8.00µin thickness and the substitute parts specifying Flash thickness.

Q: Which part should be selected for new designs?

A: For new designs, select based on specific application requirements. If the application requires 7.5A per contact current capacity, select L77DB25P1AMN. If 5A per contact is sufficient, either substitute part is acceptable. DB25P564GTXLF is recommended when board lock retention and explicit 300V voltage rating specification are required. DB25P564CTXLF is recommended when tray packaging for automated assembly is preferred.
