Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBP25S064LORLF is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Receptacle type with 25 female socket positions in 2-row layout, shell size 3 (DB, B)
• Termination Method: Solder cup termination for PCB integration
• Electrical Ratings: Current capacity of 7.5A per contact and voltage rating compatibility
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance
• Operating Conditions: Temperature range of -55°C to 125°C
• Contact Material & Finish: Copper alloy with gold GXT™ finish

The substitute part DBP25S065TLF meets all these criteria while offering active product status and enhanced specifications in certain parameters.

Parameter Comparison

Engineering Selection Recommendations

The DBP25S065TLF is a direct functional substitute for the obsolete DBP25S064LORLF. Both parts share identical connector configuration, termination method, current rating, and temperature operating range. The substitute part offers the following advantages:

• Active Product Status: DBP25S065TLF maintains active manufacturing status, ensuring long-term availability and supply chain reliability
• Enhanced Voltage Rating: Increased voltage rating of 1000V provides greater design margin compared to the 300V rating of the main part
• Improved Contact Finish Specification: Defined contact finish thickness of 30.0µin (0.76µm) versus flash thickness on the main part
• Compliance Continuity: Both parts maintain RoHS compliance and UL94 V-0 flammability rating

Selection of DBP25S065TLF eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs specified for DBP25S064LORLF.

Frequently Asked Questions (FAQ)

Q: Are DBP25S064LORLF and DBP25S065TLF mechanically interchangeable?

A: Yes. Both connectors share identical shell size 3 (DB, B) configuration, 25-position female socket layout, and solder cup termination. Mechanical fit and PCB mounting are equivalent.

Q: What is the difference in voltage rating between these parts?

A: The main part DBP25S064LORLF is rated for 300V, while the substitute DBP25S065TLF is rated for 1000V. The higher voltage rating of the substitute provides additional design margin and does not restrict its use in applications specified for 300V operation.

Q: Can DBP25S065TLF be used as a direct replacement in existing designs?

A: Yes. The substitute part meets or exceeds all critical electrical and mechanical parameters of the main part. No design modifications are required for substitution.

Q: What is the significance of the contact finish thickness difference?

A: The main part specifies flash gold finish, while the substitute specifies 30.0µin (0.76µm) thickness. The defined thickness specification on the substitute provides consistent contact resistance and wear characteristics across production batches.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in available documentation. The substitute part DBP25S065TLF is supplied in tray packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts maintain RoHS compliance?

A: Yes. Both DBP25S064LORLF and DBP25S065TLF are RoHS compliant and suitable for applications requiring restricted substance compliance.
