Amphenol ICC L77DFEF09SOL2 D-Sub 9-Position Receptacle

Part Overview

The Amphenol ICC L77DFEF09SOL2 is a 9-position D-Sub receptacle connector with female sockets, rated for panel mount and through-hole solder termination. This connector is Active status and designed for signal transmission applications requiring rated current capacity of 7.5A and operating voltage of 300V. Alternative part sources become necessary when addressing supply chain considerations, specific flange configurations, or compliance requirements within the D-Sub 9-position receptacle category.

Substitute Part Grouping Explanation

Substitute parts for the L77DFEF09SOL2 are grouped based on strict electrical and mechanical compatibility parameters. The primary criteria for substitution include: 9-position connector configuration, D-Sub female receptacle type, Shell Size 1 (DE, E) layout, solder termination, UL94 V-0 flammability rating, and copper alloy contact material with MSL 1 moisture sensitivity.

Differences in current rating, voltage rating, operating temperature range, flange feature configuration, contact form (machined versus stamped), and shell material finish do not preclude functional substitution within applications where those specifications exceed circuit requirements. Packaging format (Tray, Tube, Bulk) represents a supply and logistics variable independent of electrical function.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are compliant with UL94 V-0 flammability requirements. The L77DFEF09SOL2 features the highest voltage rating (300V) and widest operating temperature range (-55°C to 155°C) among the group, supporting applications with extended thermal and electrical demands.

For applications requiring RoHS compliance without exception, parts 1-747150-4 are excluded due to RoHS non-compliant status. The HARTING 09641127230 and 09641127235 variants and HARTING 09661116503, 09661117503, and 09661556513 are ROHS3 Compliant. TE Connectivity variants 1-5747150-3, 1-5747150-4, 1-5747150-6 are RoHS or ROHS3 Compliant. NorComp 191-009-213L571 is ROHS3 Compliant.

Parts with panel mount capability include L77DFEF09SOL2 and 191-009-213L571, suited for direct chassis integration. Remaining variants support through-hole mounting configurations. The selection between flange styles (unthreaded housing, board side, or mating side screwlock) depends on mechanical interface requirements of the specific application.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09641127230 substitute for L77DFEF09SOL2? A: Both connectors feature 9-position configuration, female receptacle sockets, Shell Size 1 (DE, E) layout, solder termination, and copper alloy contacts. The HARTING variant supports 7.5A current rating. Electrical compatibility exists within applications not exceeding 100V or requiring operation below -20°C or above 125°C, as the HARTING part has narrower voltage and temperature specifications.

Q: What is the primary difference between HARTING 09641127235 and 09641127230? A: Both parts are manufactured by HARTING with identical electrical specifications. The 09641127235 variant includes board lock features and operates with a board-side flange (4-40) configuration, compared to the unthreaded housing flange on 09641127230. Mechanical mounting interface requirements determine selection between these variants.

Q: Are TE Connectivity 1-5747150 series connectors suitable replacements? A: TE Connectivity 1-5747150 variants (-3, -4, -6) provide 9-position female receptacle configuration with solder termination and Shell Size 1 layout. Current rating is 6A versus 7.5A for the L77DFEF09SOL2, and voltage rating is 125V versus 300V. These variants operate within -55°C to 105°C range. Selection depends on whether application current and voltage requirements fall within these reduced ratings.

Q: What mounting compatibility exists between substitute parts? A: L77DFEF09SOL2 and NorComp 191-009-213L571 both support panel mount configuration. HARTING variants (09641127230, 09641127235, 09661116503, 09661117503, 09661556513) and TE Connectivity variants support through-hole mounting. Mechanical mounting interface must match application requirements.

Q: How do flange features impact substitution decisions? A: Flange features define the mechanical interface between connector and mating assembly. The L77DFEF09SOL2 uses unthreaded housing flange. HARTING 09641127235 features board-side flange with 4-40 configuration. HARTING 09661116503, 09661117503, and 09661556513 use mating-side female screwlock (4-40). NorComp 191-009-213L571 includes mating-side female screwlock with board lock feature. Application mechanical design determines compatible flange selection.

Q: Does contact finish affect electrical performance in these substitutions? A: Gold-plated contacts are specified on L77DFEF09SOL2 (20.0µin / 0.51µm thickness), 09661556513, and NorComp 191-009-213L571. Contact finish is not specified for HARTING 09641127230, 09641127235, 09661116503, and 09661117503. TE Connectivity variants use gold finish (flash or 30.0µin / 0.76µm). Contact finish affects signal integrity and corrosion resistance but does not prevent electrical function in standard applications.

Q: What packaging considerations apply to these substitute parts? A: L77DFEF09SOL2 is supplied in Tray packaging. HARTING parts are supplied in Bulk. TE Connectivity 1-5747150 variants are supplied in Tube, except 1-747150-4 in Bulk. NorComp 191-009-213L571 is supplied in Tray. Packaging format does not affect connector functionality but influences procurement quantities and logistics handling.
