L717HDBH44POL2 Equivalent & Substitute Parts

Part Overview

The L717HDBH44POL2 is a 44-position D-Sub high-density plug connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features male pins in a 3-row configuration with a DB/B shell size layout. The connector is designed for signal applications requiring robust electrical performance in industrial and commercial environments. The part maintains active product status with 1019 units in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the connector footprint, pin count, termination method, and environmental ratings are compatible.

Substitute Part Grouping Explanation

Substitute parts for the L717HDBH44POL2 are identified based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Connector type: D-Sub, High Density Plug with Male Pins
Position count: 44 positions
Row configuration: 3 rows
Shell size and layout: 3 (DB, B) High Density
Mounting method: Through Hole
Termination method: Solder
Flange feature: Board Side (4-40)
Contact type: Signal
Material flammability: UL94 V-0
Moisture sensitivity: MSL 1 (Unlimited)

The substitute part HARTING 09563617712 meets all mandatory matching parameters. Variations in shell material finish, contact finish specifications, current rating, voltage rating, and operating temperature range do not preclude substitution when the core mechanical and electrical interface parameters are equivalent.

Engineering Selection Recommendations

Both the L717HDBH44POL2 and HARTING 09563617712 maintain active product status and comply with RoHS and REACH regulatory requirements. Both connectors are classified as EAR99 for export control purposes and share identical HTSUS commodity codes.

Selection between these parts should be based on application-specific requirements:

L717HDBH44POL2 (Amphenol ICC) is suitable for applications requiring:

Extended operating temperature range (-55°C to 105°C)
Higher current capacity (3A per contact)
Tin-plated steel shell finish
Gold contact finish

09563617712 (HARTING) is suitable for applications requiring:

Standard operating temperature range (-40°C to 85°C)
Standard current capacity (2A per contact)
Nickel-plated steel shell finish
Board lock feature for enhanced mechanical retention

Both parts are RoHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09563617712 directly replace L717HDBH44POL2 in existing designs?

A: Direct mechanical and electrical replacement is possible when the application operating temperature does not exceed 85°C and current per contact does not exceed 2A. The 44-position, 3-row high-density configuration, through-hole mounting, and solder termination are identical between both parts.

Q: What are the differences in shell material finish between these connectors?

A: The L717HDBH44POL2 features a tin-plated steel shell, while the HARTING 09563617712 features a nickel-plated steel shell. Both finishes provide corrosion resistance; selection depends on specific environmental exposure and contact material compatibility requirements.

Q: Are there packaging differences between these substitute parts?

A: Yes. The L717HDBH44POL2 is supplied in tray packaging, while the HARTING 09563617712 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: What is the significance of the Board Lock feature on the HARTING part?

A: The HARTING 09563617712 includes a board lock feature in addition to grounding indents. The L717HDBH44POL2 includes grounding indents only. The board lock provides additional mechanical retention on the PCB during mating and unmating cycles.

Q: Are both connectors suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and carry MSL 1 ratings. Selection for high-reliability applications should be based on specific operating temperature, current, and environmental exposure requirements defined in the application specification.

Q: What is the contact material composition for each part?

A: The L717HDBH44POL2 uses brass contacts with gold finish (flash thickness). The HARTING 09563617712 uses copper alloy contacts. Both materials are suitable for signal-level applications with the specified current ratings.
