Substitute Part Grouping Explanation

Substitute parts for the DBP25S064TLF are identified based on strict equivalence of the following critical parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Free Hanging (In-Line)
• Termination method: Solder Cup
• Voltage rating: 300V
• Current rating: 7.5A
• Operating temperature range: -55°C to 125°C
• RoHS compliance: Yes
• Material flammability: UL94 V-0

The substitute part L77DB25S meets all these criteria and is manufactured by Amphenol ICC (Commercial Products division). Both parts maintain identical electrical performance specifications and mechanical compatibility within D-Sub 25-position receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

Both DBP25S064TLF and L77DB25S are active production parts manufactured by Amphenol ICC with full RoHS compliance and UL94 V-0 material flammability certification. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences. The L77DB25S offers higher current inventory (885 units versus 632 units), which may provide supply chain advantages for high-volume applications. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.8000) codes, ensuring consistent regulatory and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are DBP25S064TLF and L77DB25S electrically interchangeable?

A: Yes. Both connectors maintain identical voltage ratings (300V), current ratings (7.5A), and operating temperature ranges (-55°C to 125°C). They are functionally equivalent for signal applications in D-Sub 25-position receptacle circuits.

Q: What are the mechanical compatibility requirements?

A: Both parts feature identical D-Sub shell size 3 (DB, B) configuration with 25 positions arranged in 2 rows. Free hanging in-line mounting and solder cup termination are standard on both parts, ensuring direct mechanical compatibility in existing PCB layouts and connector assemblies.

Q: Do both parts meet the same compliance standards?

A: Yes. Both DBP25S064TLF and L77DB25S are RoHS compliant with UL94 V-0 material flammability ratings. Both carry MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS codes.

Q: What is the difference in contact finish specifications?

A: The DBP25S064TLF specifies gold contact finish with GXT™ treatment at flash thickness. The L77DB25S specifies gold contact finish at 8.00µin (0.203µm) thickness. Both provide gold plating for signal integrity and corrosion resistance in solder cup applications.

Q: Can I use these parts interchangeably in new designs?

A: Yes. Both parts meet all critical D-Sub 25-position receptacle specifications for signal applications. Design compatibility is determined by the D-Sub 25-position standard, which both parts satisfy.

Q: Are there any supply chain considerations?

A: The L77DB25S currently has higher inventory availability (885 units) compared to DBP25S064TLF (632 units). For applications requiring immediate procurement or high-volume orders, inventory status should be verified with your supplier.
