Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L77DFE09SAZ4VF2 are identified based on the following critical compatibility parameters:

• Connector Layout: Shell Size 1 (DE, E) — ensures physical and electrical compatibility with mating plugs
• Position Count: 9 positions in 2-row configuration — maintains identical pinout
• Mounting Configuration: Through Hole, Right Angle orientation — ensures mechanical fit in panel mount applications
• Termination Method: Solder — compatible with PCB assembly processes
• Flange Type: Female Screwlock (4-40) — identical mating interface
• Contact Type: Signal-level with gold finish — electrical performance requirements
• RoHS Compliance: Required for current supply chain and regulatory standards

The substitute part 5745395-3 (TE Connectivity AMPLIMITE HD-20 series) meets these core compatibility criteria. Variations in secondary parameters such as current rating, voltage rating, operating temperature range, and contact finish thickness are documented and require engineering evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active in production and RoHS compliant. Selection between L77DFE09SAZ4VF2 and 5745395-3 depends on application-specific electrical requirements:

The L77DFE09SAZ4VF2 provides higher current rating (7.5A versus 6A) and higher voltage rating (300V versus 125V), with broader operating temperature range (-55°C to 155°C versus -55°C to 105°C). These characteristics make the Amphenol ICC part suitable for higher-power signal applications and extended thermal environments.

The 5745395-3 features thicker gold plating (30.0µin versus 20.0µin), which may offer extended contact wear resistance in high-cycle mating applications. However, the reduced current and voltage ratings, along with narrower operating temperature range, limit this part to lower-power signal distribution applications within standard industrial temperature bands.

Frequently Asked Questions (FAQ)

Q: Can 5745395-3 be substituted for L77DFE09SAZ4VF2 in all applications? A: Physical and electrical compatibility is confirmed for connector layout and pinout. However, application requirements for current rating (6A versus 7.5A), voltage rating (125V versus 300V), and operating temperature range (-55°C to 105°C versus -55°C to 155°C) must be evaluated. Direct substitution is not universal; application electrical and thermal specifications must not exceed the 5745395-3 ratings.

Q: What are the key physical compatibility factors? A: Both connectors share identical shell size (1 / DE, E), position count (9), mounting orientation (right angle through hole), termination method (solder), and screwlock interface (4-40 female). These parameters ensure mechanical fit and mating with standard D-Sub plugs in the same layout class.

Q: Are there packaging differences between these parts? A: L77DFE09SAZ4VF2 packaging is specified as standard; 5745395-3 is supplied in tube packaging. Packaging does not affect electrical or mechanical performance and is relevant only for procurement and assembly handling.

Q: How do contact finish differences affect performance? A: The 5745395-3 provides thicker gold plating (30.0µin versus 20.0µin). Both finishes meet gold contact specifications for signal-level applications. Thicker plating may reduce contact wear in high-cycle mating environments but does not change electrical properties for single-pair contact resistance.

Q: What compliance certifications apply to both parts? A: Both parts are RoHS compliant. Both carry UL94 V-0 flammability rating, meeting safety standards for enclosed applications. Both are classified as EAR99 for export control purposes.
