L17HTHAS4F4C D-Sub High Density Receptacle 26 Position Connector

Part Overview

The L17HTHAS4F4C is a 26-position D-Sub high density receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole, right-angle solder-terminated connector features female sockets with a mating side female screwlock (4-40) and is designed for signal applications. The connector is actively produced and RoHS compliant, with 685 units currently in stock. Alternative equivalent parts may be required due to inventory constraints, specific packaging requirements, or application-specific compliance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L17HTHAS4F4C is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub, High Density
• Connector type: Receptacle, Female Sockets
• Number of positions: 26
• Number of rows: 3
• Shell size and layout: 2 (DA, A) High Density
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Flange feature: Mating Side, Female Screwlock (4-40)
• Contact type: Signal
• Backset spacing: 0.350" (8.89mm)
• Material flammability rating: UL94 V-0
• Contact material: Copper Alloy
• Features: Board Lock

The substitute parts 09562525613 and 09562527613, both manufactured by HARTING, meet all mandatory matching parameters. Differences exist in shell material finish (nickel plated versus tin plated), current rating (2A versus 3A), operating temperature range, and packaging format. These differences represent trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

L17HTHAS4F4C (Amphenol ICC) is the primary specification. This connector is actively produced, RoHS compliant, and rated for 3A current and 300V voltage. The operating temperature range extends from -55°C to 150°C, supporting extended environmental conditions. The tin-plated steel shell with gold contact finish provides specified corrosion resistance characteristics.

09562525613 (HARTING) is functionally equivalent for applications where the reduced current rating (2A) and narrower operating temperature range (-40°C to 85°C) are acceptable. This part is ROHS3 compliant and available in tray packaging. The nickel-plated shell and gold or gold-palladium contact finish provide alternative surface characteristics. Higher inventory availability (1406 units) supports supply chain flexibility.

09562527613 (HARTING) is functionally equivalent for applications where the reduced current rating (2A) and narrower operating temperature range (-40°C to 85°C) are acceptable. This part is ROHS3 compliant and available in bulk packaging. The nickel-plated steel shell is specified; contact finish details are not provided. Higher inventory availability (1070 units) supports supply chain flexibility.

Selection between these parts depends on application-specific requirements for current capacity, operating temperature range, shell material finish, and packaging format. All three parts satisfy the core D-Sub high density 26-position receptacle specification with identical mechanical and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can 09562525613 or 09562527613 be used as direct replacements for L17HTHAS4F4C?

A: Both HARTING parts are mechanically and electrically compatible for mating and mounting. However, the reduced current rating (2A versus 3A) and narrower operating temperature range (-40°C to 85°C versus -55°C to 150°C) must be evaluated against application requirements. If the application operates within the HARTING temperature range and current draw does not exceed 2A, substitution is valid.

Q: What is the difference between 09562525613 and 09562527613?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is packaging format: 09562525613 is supplied in trays, while 09562527613 is supplied in bulk. Contact finish specifications are provided for 09562525613 (gold or gold-palladium at 30.0µin thickness) but not specified for 09562527613.

Q: Why does the L17HTHAS4F4C have a higher current rating than the HARTING substitutes?

A: Current rating differences reflect design and material choices by each manufacturer. The L17HTHAS4F4C is rated for 3A, while both HARTING parts are rated for 2A. Applications requiring current capacity above 2A must use the L17HTHAS4F4C or confirm HARTING part suitability through direct manufacturer consultation.

Q: Are there temperature limitations when substituting with HARTING parts?

A: Yes. The L17HTHAS4F4C operates from -55°C to 150°C, while both HARTING substitutes operate from -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must use the L17HTHAS4F4C.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: The L17HTHAS4F4C features a tin-plated steel shell, while both HARTING substitutes feature nickel-plated steel shells. Both finishes provide corrosion resistance; the choice depends on application environment and specific corrosion resistance requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The L17HTHAS4F4C is RoHS compliant. Both HARTING parts are ROHS3 compliant, which represents a more recent RoHS standard revision. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: Does packaging format affect connector performance?

A: No. Packaging format (tray versus bulk) affects handling, storage, and logistics but does not affect electrical or mechanical performance. Selection between 09562525613 (tray) and 09562527613 (bulk) depends on procurement and inventory management requirements.

Q: What voltage rating applies to the HARTING substitutes?

A: Voltage rating is not specified for either HARTING part (09562525613 or 09562527613). The L17HTHAS4F4C is rated for 300V. Applications requiring confirmed voltage rating specifications must use the L17HTHAS4F4C or obtain voltage rating confirmation directly from HARTING.
