L717SDEG09P - D-Sub 9 Position Connector

Part Overview

The Amphenol ICC L717SDEG09P is a 9-position D-Sub plug connector with male pins, designed for signal-level applications requiring solder cup termination. This connector features a free-hanging cable-side mounting configuration with M3 grounding indents and operates across a temperature range of -55°C to 105°C with a 250V voltage rating.

The product is currently active in inventory with 847 pieces available. Due to design evolution, mounting preference variations, and manufacturer transitions, equivalent substitutes from NorComp Inc. are available that maintain compatibility across the critical D-Sub 9-position connector form factor while offering alternatives in mounting style and shell material finishes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717SDEG09P is determined by the following non-negotiable parameters:

• 9-position D-Sub connector configuration with Shell Size 1 (DE, E) layout
• Male pin connector type with 2-row arrangement
• Solder cup termination method
• Stamped contact form with gold finish (flash thickness)
• Steel shell with grounding indents
• Signal contact type with UL94 V-0 flammability rating
• Black color designation

The NorComp Inc. 171 series substitutes (171-009-102L001, 171-009-103L001, 171-009-103L011, 171-009-103L021) satisfy these core electrical and mechanical parameters. Key differences among substitutes involve:

• Mounting style: Panel mount versus free-hanging configuration
• Flange feature: Unthreaded housing, M3 cable-side, or 4-40 cable-side options
• Shell material finish: Tin plated versus nickel plated
• Current rating: 5A (higher than original 3A)
• Dielectric material: Polybutylene Terephthalate (PBT) versus thermoplastic composition
• Operating temperature range: -50°C to 100°C (slightly narrower than original)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute — 171-009-103L021 (NorComp Inc.)

The 171-009-103L021 is the recommended primary substitute for new designs. This part is active in production with the highest inventory availability (3,571 pieces), carries ROHS3 compliance, and REACH Unaffected designation. It provides the most direct functional equivalent with cable-side 4-40 flange mounting, meeting all core D-Sub 9-position connector requirements with higher current capacity (5A vs. 3A).

Alternative Substitute — 171-009-103L011 (NorComp Inc.)

The 171-009-103L011 offers identical electrical and mechanical specifications to the 171-009-103L021, with the same flange configuration (cable-side 4-40) and nickel-plated shell finish. Selection between these two depends on inventory availability and procurement lead times.

Legacy Substitute — 171-009-103L001 (NorComp Inc.)

The 171-009-103L001 remains in active production and is functionally compatible. This part features unthreaded housing/shell flange design rather than cable-side mounting, making it suitable only for panel-mount applications. It maintains all electrical specifications and compliance status equivalent to the primary substitute.

Obsolete Substitute — 171-009-102L001 (NorComp Inc.)

The 171-009-102L001 is marked obsolete and should not be selected for new designs or applications requiring long-term support. Although electrically compatible with a tin-plated steel shell matching the original L717SDEG09P finish, its discontinued status presents supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can I use a 171-009-103L011 or 171-009-103L021 in place of the L717SDEG09P in an existing design?

A: Substitution is possible with mounting consideration. The L717SDEG09P is designed for free-hanging cable-side mounting with M3 threads. The 171-009-103L011 and 171-009-103L021 feature 4-40 cable-side threading, which is mechanically compatible with standard D-Sub mounting hardware. Panel-mount designs (171-009-103L001) require different mounting interfaces and are not suitable for free-hanging in-line applications.

Q: What is the impact of the different shell material finishes (tin-plated vs. nickel-plated)?

A: The L717SDEG09P uses a tin-plated steel shell. Substitute parts employ nickel-plated steel shells (171-009-103L001, 171-009-103L011, 171-009-103L021). Both finishes provide corrosion protection and electromagnetic shielding. Nickel plating offers superior environmental resistance in harsh conditions, while tin plating provides lower contact resistance at assembly. The contact surfaces on all parts maintain identical gold-flash plating, which determines actual signal integrity.

Q: Does the 5A current rating of substitute parts affect compatibility?

A: The substitute parts are rated for 5A versus the original 3A specification. A higher current rating is a superset capability and does not restrict the part's use in 3A applications. The substitute parts are electrically compatible and safe for use at or below the original design's 3A current requirements.

Q: How do the different operating temperature ranges affect selection?

A: The L717SDEG09P operates from -55°C to 105°C. The NorComp substitutes operate from -50°C to 100°C, representing a 5°C narrower range at both extremes. For applications operating within the -50°C to 100°C window, substitutes are fully compatible. Applications requiring -55°C operation must retain the original L717SDEG09P.

Q: What is the significance of ROHS3 versus RoHS Compliant status?

A: RoHS Compliant indicates adherence to Directive 2002/95/EC. ROHS3 Compliant indicates adherence to Directive 2011/65/EU and its amendments, representing the current regulatory requirement in the European Union. ROHS3 is the active standard; ROHS3-compliant parts are preferred for new designs and long-term production support.

Q: Can I use the 171-009-103L001 (panel-mount) as a substitute in a cable-mounted application?

A: No. The 171-009-103L001 features unthreaded housing/shell flange design intended for panel installation, not cable-side or in-line mounting. Using this part in a free-hanging cable application would require custom mechanical adaptation and is not recommended. Select 171-009-103L011 or 171-009-103L021 for cable-side mounting compatibility.

Q: Why do the substitute parts have wider wire gauge specifications (20-28 AWG vs. 20 AWG)?

A: The original L717SDEG09P is specified for 20 AWG termination only. The NorComp substitutes accept a wider range (20-28 AWG) within their solder cup termination design. This expanded range provides design flexibility without compromising compatibility for the original 20 AWG specification.
