Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L177DFE09SA are identified based on the following critical parameters that determine functional equivalence:

Core Compatibility Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting configuration: Right Angle, Through Hole
• Termination method: Solder
• Voltage rating: 300V
• Operating temperature range: -55°C to 125°C
• Shell material: Steel, Tin Plated
• Contact material: Copper Alloy or Phosphor Bronze
• RoHS compliance: Compliant
• Flammability rating: UL94 V-0

The substitute parts DE09S564TLF and DE09S565MTLF satisfy these core parameters. Variations in current rating per contact, backset spacing, contact finish thickness, and dielectric material composition do not preclude substitution when the application requirements fall within the specified electrical and mechanical tolerances of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

L177DFE09SA Selection Criteria: The L177DFE09SA is suitable for applications requiring a 7.5A current rating per connector. This part features panel mount capability with mounting brackets and maintains a backset spacing of 0.319" (8.10mm). The glass-filled thermoplastic dielectric provides enhanced mechanical stability. Select this part when the application circuit design specifies the higher current capacity and panel-mount configuration is required.

DE09S564TLF Selection Criteria: The DE09S564TLF is suitable for applications with current requirements of 5A per contact maximum. This part is supplied in bulk packaging and features a backset spacing of 0.409" (10.40mm). The thermoplastic dielectric without glass filling provides standard mechanical properties. Select this part when bulk packaging is preferred and the application current requirements do not exceed 5A per contact.

DE09S565MTLF Selection Criteria: The DE09S565MTLF is suitable for applications with current requirements of 5A per contact maximum. This part is supplied in tray packaging and features mounting brackets identical to the L177DFE09SA. The glass-filled thermoplastic dielectric matches the L177DFE09SA specification. The backset spacing is 0.370" (9.40mm), positioned between the L177DFE09SA and DE09S564TLF specifications. Select this part when tray packaging is required, mounting brackets are necessary, and the application current requirements do not exceed 5A per contact.

Compliance Basis: All three parts maintain active product status, full RoHS compliance, UL94 V-0 flammability rating, and identical voltage and temperature specifications. Selection between these parts is determined by current rating requirements, packaging format, backset spacing tolerance, and mounting bracket necessity.

Frequently Asked Questions (FAQ)

Q: Can DE09S564TLF or DE09S565MTLF be used as direct replacements for L177DFE09SA?

A: Both substitute parts are functionally compatible with L177DFE09SA in applications where the circuit current requirement does not exceed 5A per contact. The L177DFE09SA supports 7.5A, while both substitutes are rated for 5A per contact. If the application circuit operates at or below 5A per contact, either substitute part provides equivalent electrical and mechanical performance. Backset spacing and mounting bracket availability differ between parts and must be verified against PCB layout requirements.

Q: What is the difference between the packaging formats?

A: L177DFE09SA and DE09S565MTLF are supplied in tray packaging, suitable for automated assembly processes. DE09S564TLF is supplied in bulk packaging, suitable for manual assembly or alternative handling methods. Packaging format does not affect electrical or mechanical performance.

Q: How do backset spacing differences affect substitution?

A: Backset spacing is the distance from the connector mounting surface to the contact insertion point. L177DFE09SA specifies 0.319" (8.10mm), DE09S565MTLF specifies 0.370" (9.40mm), and DE09S564TLF specifies 0.409" (10.40mm). These differences affect PCB layout and mating connector alignment. Verify that the substitute part's backset spacing is compatible with the existing PCB design and mating connector before selection.

Q: Are mounting brackets available on all substitute parts?

A: L177DFE09SA and DE09S565MTLF both include mounting brackets as a standard feature. DE09S564TLF does not list mounting brackets as a feature. If the application requires mounting brackets for panel installation, select either L177DFE09SA or DE09S565MTLF.

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

A: L177DFE09SA and DE09S565MTLF specify contact finish thickness of 30.0µin (0.76µm). DE09S564TLF specifies flash thickness, which is a minimal plating layer. Both finishes provide gold contact protection. Flash thickness is suitable for applications with standard contact wear expectations, while the 30.0µin specification provides additional contact durability for high-cycle mating applications.

Q: Do dielectric material differences affect performance?

A: L177DFE09SA and DE09S565MTLF use glass-filled thermoplastic dielectric, while DE09S564TLF uses standard thermoplastic dielectric. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range. Glass-filled dielectric provides enhanced mechanical rigidity and dimensional stability. Standard thermoplastic dielectric is suitable for applications without enhanced mechanical stress requirements.

Q: Are all three parts RoHS compliant?

A: Yes. L177DFE09SA, DE09S564TLF, and DE09S565MTLF are all RoHS compliant with MSL rating of 1 (Unlimited). All parts meet identical compliance standards for hazardous substance restrictions.

Q: What determines the choice between Copper Alloy and Phosphor Bronze contact materials?

A: L177DFE09SA and DE09S564TLF use Copper Alloy contacts. DE09S565MTLF uses Phosphor Bronze contacts. Both materials provide equivalent electrical conductivity and contact reliability. Phosphor Bronze offers enhanced spring properties and wear resistance in high-cycle mating applications. Copper Alloy provides standard contact performance. Selection is based on application mating cycle requirements.
