• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations in Substitute Parts:

• Termination method (Solder vs. Solder Cup)
• Contact finish specification (Gold vs. Gold, GXT™)
• Contact finish thickness (20.0µin vs. Flash or 30.0µin)
• Voltage rating (300V vs. 1000V)
• Operating temperature upper limit (-55°C ~ 155°C vs. -55°C ~ 125°C)
• Mounting type (unspecified vs. Free Hanging In-Line)
• Packaging format (unspecified vs. Tray or Bulk)
• Series designation (DF vs. DP)

The identified substitute parts DEP09S064TLF and DEP09S065TLF satisfy all mandatory matching parameters while offering alternative termination and contact finish specifications suitable for equivalent signal-level D-Sub receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The L77DFE09SMP10 remains the specified component for applications requiring the exact solder termination configuration with the defined operating temperature range of -55°C to 155°C and 300V voltage rating. This part maintains Active product status with established inventory levels.

Substitute Part Selection Criteria:

DEP09S064TLF (Tray Packaging): This substitute is suitable for applications where solder cup termination is acceptable and higher voltage rating (1000V) provides additional design margin. The Flash contact finish thickness meets signal-level requirements. Inventory availability is 1234 units. This part is appropriate when the application operates within the -55°C to 125°C temperature range and does not require the extended upper temperature capability of the primary part.

DEP09S065TLF (Bulk Packaging): This substitute offers identical electrical and mechanical compatibility to DEP09S064TLF with the addition of specified contact finish thickness (30.0µin). Bulk packaging format provides cost efficiency for high-volume applications. Inventory availability is 1069 units. Selection between DEP09S064TLF and DEP09S065TLF depends on packaging requirements and contact finish thickness specifications for the application.

Compliance Basis: All three parts maintain RoHS Compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity classification. All parts are manufactured by Amphenol ICC and carry Active product status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can DEP09S064TLF or DEP09S065TLF be used as direct replacements for L77DFE09SMP10?

A: DEP09S064TLF and DEP09S065TLF are functionally equivalent for signal-level D-Sub receptacle applications. The primary difference is termination method: L77DFE09SMP10 uses solder termination while the substitute parts use solder cup termination. Both termination methods provide equivalent electrical performance for 9-position D-Sub receptacle connections. Selection depends on the PCB or cable assembly design requirements.

Q: What is the difference between the two substitute parts?

A: DEP09S064TLF and DEP09S065TLF differ in packaging format and contact finish thickness specification. DEP09S064TLF is supplied in Tray packaging with Flash contact finish thickness. DEP09S065TLF is supplied in Bulk packaging with 30.0µin (0.76µm) contact finish thickness. Both parts are electrically and mechanically identical otherwise.

Q: Are there temperature limitations when using substitute parts?

A: The substitute parts DEP09S064TLF and DEP09S065TLF have an operating temperature range of -55°C to 125°C, compared to the primary part's -55°C to 155°C range. If the application requires operation above 125°C, the L77DFE09SMP10 must be used. For applications operating within -55°C to 125°C, the substitute parts are fully compatible.

Q: What is the voltage rating difference?

A: The L77DFE09SMP10 is rated for 300V, while DEP09S064TLF and DEP09S065TLF are rated for 1000V. The higher voltage rating of the substitute parts provides additional design margin and is suitable for all applications requiring 300V or less. There is no compatibility issue when substituting a higher-rated part in a lower-voltage application.

Q: Does the contact finish difference affect performance?

A: All three parts feature gold contact finish suitable for signal-level applications. The L77DFE09SMP10 specifies 20.0µin (0.51µm) thickness, DEP09S064TLF specifies Flash thickness, and DEP09S065TLF specifies 30.0µin (0.76µm) thickness. These variations are within acceptable ranges for signal-level D-Sub connectors and do not affect electrical performance or compatibility.

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

A: For new designs, either DEP09S064TLF or DEP09S065TLF can be selected based on packaging requirements. DEP09S065TLF in Bulk packaging is typically preferred for high-volume production due to cost efficiency. DEP09S064TLF in Tray packaging is suitable for lower-volume applications or when tray packaging is required for assembly line compatibility.

Q: Are all parts RoHS compliant?

A: Yes, L77DFE09SMP10, DEP09S064TLF, and DEP09S065TLF are all RoHS Compliant. All parts meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring compliance with industry standards and environmental regulations.
