17EHD044SAM100 D-Sub High Density Receptacle Equivalent & Substitute Parts

Part Overview

The 17EHD044SAM100 is a 44-position D-Sub high density receptacle connector manufactured by Amphenol ICC (Commercial Products). This female sockets connector features solder cup termination and is designed for free hanging in-line mounting applications. The connector maintains an active product status and is RoHS compliant with unlimited moisture sensitivity level rating.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits alternative qualified components that meet the same electrical and mechanical requirements. The 17EHD044SAM100 has one qualified substitute available that maintains functional compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 17EHD044SAM100 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub, High Density
• Connector type: Receptacle, Female Sockets
• Number of positions: 44
• Number of rows: 3
• Shell size and connector layout: 3 (DB, B) High Density
• Mounting type: Free Hanging (In-Line)
• Termination method: Solder Cup
• Shell material and finish: Steel, Nickel Plated
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• Operating temperature range: -55°C ~ 105°C
• RoHS compliance: Required

The substitute part 10090770-S444ALF meets all mandatory matching parameters and qualifies as a direct functional equivalent. Both connectors share identical mechanical form factors, electrical contact configurations, and environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 10090770-S444ALF qualifies as a direct substitute for the 17EHD044SAM100 based on matching mechanical form factor, electrical contact configuration, and environmental compliance certifications. Both connectors are active products manufactured by Amphenol ICC divisions and maintain RoHS compliance with unlimited moisture sensitivity level ratings.

The substitute part exhibits the following differences that do not prevent substitution:

Current Rating Differential: The 10090770-S444ALF is rated at 2.5A per contact compared to the 17EHD044SAM100 at 3A. This difference is acceptable in applications where the circuit current requirement does not exceed 2.5A per contact.

Voltage Rating Differential: The 10090770-S444ALF is rated at 250V compared to the 17EHD044SAM100 at 125V. The higher voltage rating of the substitute provides additional margin and does not restrict substitution.

Contact Finish Thickness: The 10090770-S444ALF features flash gold plating compared to the 17EHD044SAM100 at 30.0µin (0.76µm). Both gold finishes provide equivalent contact reliability for signal-level applications.

Dielectric Material: The 10090770-S444ALF uses thermoplastic glass-filled material compared to polyamide nylon glass-filled material in the 17EHD044SAM100. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range.

Packaging: The 10090770-S444ALF is supplied in tray packaging, which may require adjustment to receiving and storage procedures.

Selection between these parts should be based on application current requirements, available inventory, and packaging compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 10090770-S444ALF be used in place of the 17EHD044SAM100 in all applications?

A: The 10090770-S444ALF is a functional equivalent for applications where the circuit current per contact does not exceed 2.5A. If your application requires the full 3A per contact rating of the 17EHD044SAM100, the substitute is not appropriate.

Q: What is the difference between the contact finish specifications?

A: The 17EHD044SAM100 specifies 30.0µin (0.76µm) gold plating thickness, while the 10090770-S444ALF uses flash gold plating. Flash plating is a thin electrodeposited layer that provides contact protection. Both finishes are suitable for signal-level D-Sub connectors.

Q: Are there any mechanical compatibility issues between these connectors?

A: No. Both connectors share identical mechanical specifications including shell size (3 DB/B high density), 44-position configuration, 3-row layout, and free hanging in-line mounting. They are mechanically interchangeable.

Q: What is the significance of the different dielectric materials?

A: The 17EHD044SAM100 uses polyamide nylon while the 10090770-S444ALF uses thermoplastic, both glass-filled. Both materials meet UL94 V-0 flammability requirements and operate across -55°C to 105°C. The material difference does not affect electrical or mechanical performance in this application.

Q: Does the higher voltage rating of the substitute part create any issues?

A: No. The 10090770-S444ALF is rated at 250V compared to 125V for the 17EHD044SAM100. A higher voltage rating provides additional safety margin and does not restrict substitution in applications designed for 125V operation.

Q: How does packaging affect the substitution decision?

A: The 17EHD044SAM100 packaging is not specified, while the 10090770-S444ALF is supplied in tray packaging. If your assembly process requires specific packaging formats, verify compatibility with receiving, storage, and pick-and-place equipment before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the 17EHD044SAM100 and 10090770-S444ALF are RoHS compliant with unlimited moisture sensitivity level (MSL 1) ratings, suitable for standard storage and handling conditions.

Q: What is the inventory status of each part?

A: The 17EHD044SAM100 has 998 pieces in stock. The 10090770-S444ALF has 2095 pieces in stock. Substitute selection may be driven by inventory availability and lead time requirements.
