Amphenol ICC L177DFEG09S1AMN D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The L177DFEG09S1AMN is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, right-angle solder connector features female sockets with board-side M3 flange mounting and is classified as an active product. The connector is designed for signal applications requiring 300V operation across an extended temperature range of -55°C to 125°C.

Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or when design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L177DFEG09S1AMN is determined by strict alignment of the following core parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Mounting type: Right Angle, Through Hole
• Termination method: Solder
• Voltage rating: 300V
• Operating temperature range: -55°C to 125°C
• Shell material and finish: Steel, Tin Plated
• Material flammability rating: UL94 V-0
• RoHS compliance: Compliant

Allowable Variations:

• Flange feature configuration (board-side M3 versus housing/shell unthreaded)
• Current rating per contact (7.5A versus 5A per contact)
• Contact finish thickness (30.0µin versus Flash)
• Backset spacing tolerance (within connector design specifications)
• Dielectric material composition (thermoplastic with or without glass fill)
• Contact material (Copper Alloy versus Phosphor Bronze)
• Packaging format (Tray versus Bulk)

The substitute parts DE09S564TLF and DE09S565MTLF meet all mandatory matching parameters and are therefore qualified as electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three connectors—L177DFEG09S1AMN, DE09S564TLF, and DE09S565MTLF—are active products manufactured by Amphenol ICC with RoHS compliance and UL94 V-0 flammability certification. All operate across the identical temperature range of -55°C to 125°C and support 300V applications.

L177DFEG09S1AMN is the primary specification with board-side M3 flange mounting and a 7.5A current rating. This configuration is suitable for applications requiring dedicated panel-mount installation with higher current capacity.

DE09S564TLF provides electrical and mechanical equivalence with housing/shell unthreaded flange configuration and 5A per contact current rating. This part is supplied in bulk packaging and features flash contact finish thickness. Selection of this substitute is appropriate when bulk packaging accommodates procurement requirements and the 5A per contact rating satisfies application current demands.

DE09S565MTLF provides electrical and mechanical equivalence with housing/shell unthreaded flange configuration, 5A per contact current rating, and phosphor bronze contact material. This part is supplied in tray packaging with 30.0µin contact finish thickness matching the primary specification. Selection of this substitute is appropriate when tray packaging is required and the 5A per contact rating satisfies application current demands.

Frequently Asked Questions (FAQ)

Q: Can DE09S564TLF and DE09S565MTLF be used interchangeably with L177DFEG09S1AMN?

A: Both substitute parts meet the mandatory electrical and mechanical parameters for D-Sub 9-position receptacle connectors. However, flange feature differences exist. The L177DFEG09S1AMN features board-side M3 mounting, while both substitutes feature housing/shell unthreaded flanges. Current rating differences also exist: the primary part supports 7.5A, while substitutes support 5A per contact. Application requirements determine interchangeability.

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

A: DE09S564TLF and DE09S565MTLF differ in three areas: packaging format (bulk versus tray), contact finish thickness (flash versus 30.0µin), and contact material (copper alloy versus phosphor bronze). Both maintain identical electrical ratings, voltage specifications, and temperature operating ranges.

Q: Does the backset spacing variation affect compatibility?

A: Backset spacing differs across the three parts: L177DFEG09S1AMN at 0.406" (10.30mm), DE09S564TLF at 0.409" (10.40mm), and DE09S565MTLF at 0.370" (9.40mm). These variations fall within D-Sub connector design tolerances for the 1 (DE, E) shell size and layout. Mechanical fit and mating compatibility remain within specification.

Q: Are all three parts RoHS compliant?

A: Yes. L177DFEG09S1AMN, DE09S564TLF, and DE09S565MTLF are all RoHS compliant. DE09S565MTLF additionally carries REACH Unaffected status.

Q: What packaging options are available?

A: L177DFEG09S1AMN and DE09S565MTLF are supplied in tray packaging. DE09S564TLF is supplied in bulk packaging. Packaging selection depends on procurement and inventory management requirements.

Q: How do current ratings compare?

A: L177DFEG09S1AMN supports 7.5A total current. DE09S564TLF and DE09S565MTLF support 5A per contact. Applications requiring current levels above 5A per contact require the primary specification L177DFEG09S1AMN.

Q: What is the difference between gold and gold GXT™ contact finishes?

A: L177DFEG09S1AMN features standard gold contact finish at 30.0µin thickness. DE09S564TLF features gold GXT™ finish at flash thickness. DE09S565MTLF features gold GXT™ finish at 30.0µin thickness. All finishes provide equivalent electrical performance for signal applications at 300V.
