L177DFEH09SOL2RM8 Equivalent & Substitute Parts

Part Overview

The L177DFEH09SOL2RM8 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, through-hole solder termination connector features female sockets with a board-side flange and board lock mechanism. The connector is actively produced and maintains full stock availability of 1010 pieces. D-Sub receptacle connectors serve as mating interfaces for signal transmission in industrial, telecommunications, and computing applications where standardized 9-position configurations are required. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when specific application requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L177DFEH09SOL2RM8 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and connector layout: 1 (DE, E)
• Termination method: Solder
• Mounting configuration: Through Hole
• Flange feature: Board Side (4-40)
• Contact type: Signal
• Contact material: Copper Alloy
• Contact form: Machined

Allowable Variation Parameters: Substitute parts may differ in the following specifications while maintaining functional compatibility:

• Mounting type (Panel Mount vs. Through Hole only)
• Voltage rating (substitute may be lower than primary part)
• Operating temperature range (substitute may have narrower range)
• Contact finish specifications
• Dielectric material composition
• Packaging format (Tray vs. Bulk)
• Color designation
• Series designation

The substitute part HARTING 09641127235 meets all critical matching parameters and is classified as a functional equivalent for applications where the specified allowable variations are acceptable.

Engineering Selection Recommendations

Primary Part Selection: L177DFEH09SOL2RM8

The L177DFEH09SOL2RM8 maintains active product status with robust inventory availability (1010 pieces in stock). This connector is RoHS Compliant and carries REACH Unaffected designation, meeting current regulatory requirements. The 300V voltage rating and -55°C to 125°C operating temperature range provide extended performance envelope for demanding industrial applications. The UL94 V-0 flammability rating confirms suitability for safety-critical installations.

Substitute Part Selection: HARTING 09641127235

The HARTING 09641127235 qualifies as a functional substitute when the primary part is unavailable. This connector maintains active product status with higher inventory availability (1362 pieces in stock). ROHS3 Compliance and REACH Unaffected status satisfy regulatory requirements. The substitute part exhibits two specification differences:

1. Voltage Rating Reduction: The substitute operates at 100V maximum versus 300V for the primary part. This reduction is acceptable only for applications with voltage requirements not exceeding 100V.

2. Operating Temperature Range Narrowing: The substitute operates from -20°C to 125°C versus -55°C to 125°C for the primary part. This narrower range excludes applications requiring operation below -20°C.

Both connectors share identical current rating (7.5A), flammability classification (UL94 V-0), and mechanical configuration. The substitute includes integrated filter and board lock features. Selection between primary and substitute parts depends on application voltage and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09641127235 directly replace the L177DFEH09SOL2RM8 in all applications?

A: The HARTING 09641127235 functions as a direct mechanical and electrical substitute only for applications operating at or below 100V and within the -20°C to 125°C temperature range. Applications requiring the full 300V rating or operation below -20°C must use the primary L177DFEH09SOL2RM8 part.

Q: What are the critical compatibility factors for D-Sub 9-position receptacle substitution?

A: Critical factors include connector style (D-Sub), connector type (Receptacle, Female Sockets), position count (9), row configuration (2), shell size (1 DE/E), mounting method (Through Hole), termination type (Solder), and flange configuration (Board Side 4-40). All substitute parts must match these parameters exactly.

Q: How do the packaging formats differ between these parts?

A: The L177DFEH09SOL2RM8 ships in Tray packaging, while the HARTING 09641127235 ships in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence inventory management and handling procedures.

Q: Are both parts compliant with current environmental regulations?

A: Yes. The L177DFEH09SOL2RM8 is RoHS Compliant, and the HARTING 09641127235 is ROHS3 Compliant. Both parts carry REACH Unaffected designation and EAR99 export classification. Both meet UL94 V-0 flammability requirements.

Q: What is the significance of the board lock feature on the HARTING substitute?

A: Both the primary and substitute parts include board lock mechanisms. This feature provides mechanical retention on the PCB through the board-side flange (4-40 configuration), preventing accidental disconnection during assembly and operation.

Q: Can these connectors be used interchangeably with other D-Sub shell sizes?

A: No. Both connectors are specified for Shell Size 1 (DE, E) configuration. They are not compatible with other D-Sub shell sizes such as Shell Size 2 (DB, D) or Shell Size 3 (DA, A). Shell size determines physical dimensions and pin spacing.

Q: What contact finish specifications apply to these receptacles?

A: The L177DFEH09SOL2RM8 specifies gold contact finish at 30.0µin (0.76µm) thickness. The HARTING 09641127235 does not provide contact finish specifications in available documentation. Contact finish affects signal integrity and corrosion resistance in high-reliability applications.

Q: Are these parts suitable for high-frequency signal transmission?

A: Both connectors are classified as signal-type contacts with machined copper alloy construction. Suitability for specific high-frequency applications depends on impedance matching, shielding requirements, and signal frequency specifications not provided in the component parameters.
