Equivalent & Substitute Parts for L717SDEG09PC309

Part Overview

The L717SDEG09PC309 is a 9-position D-Sub plug connector manufactured by Amphenol ICC, featuring male pins with solder cup termination and cable-side mounting. This connector is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating. The device operates across an industrial temperature range of -55°C to 105°C with a 250V voltage rating and 3A current capacity.

Substitute parts are necessary when the original Amphenol ICC component becomes unavailable, when alternative sourcing reduces lead times, or when design flexibility permits selection from qualified equivalent connectors that maintain electrical and mechanical compatibility within the same D-Sub category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717SDEG09PC309 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Termination: Solder Cup
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• Contact Finish: Gold

Allowable Variation Parameters:

• Mounting Type: Free Hanging (In-Line) vs. Panel Mount (functional difference, not electrical incompatibility)
• Shell Material Finish: Tin Plated vs. Nickel Plated (both provide corrosion protection)
• Current Rating: 3A vs. 5A (higher rating acceptable for same voltage/position configuration)
• Operating Temperature Range: -55°C ~ 105°C vs. -50°C ~ 100°C (subset compatibility acceptable if application requirements fall within narrower range)
• Contact Material: Brass vs. Copper Alloy (both acceptable for signal-level D-Sub applications)
• Dielectric Material: Thermoplastic, Glass Filled vs. Polybutylene Terephthalate (PBT), Glass Filled (both meet UL94 V-0)
• Wire Gauge: 20 AWG vs. 20-28 AWG (broader range acceptable)

Compliance Consideration: All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) rating, ensuring environmental and moisture compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs): 171-009-103L021 is the preferred substitute when panel mount configuration is acceptable. This part maintains Active product status, ROHS3 compliance, and unlimited MSL rating. The higher current rating (5A vs. 3A) provides design margin for signal-level applications. Cable-side flange with 4-40 mounting accommodates standard mechanical integration. Inventory availability (3571 pcs) ensures supply continuity.

Secondary Substitute (Active Status, Alternative Flange): 171-009-103L011 provides identical electrical specifications to 171-009-103L021 with alternative cable-side flange configuration (4-40 vs. unthreaded). Selection between these two NorComp variants depends on mechanical mounting requirements. Both maintain Active status and full compliance certifications.

Tertiary Substitute (Active Status, Housing-Mounted Flange): 171-009-103L001 offers panel mount configuration with housing/shell unthreaded flange. This variant is suitable for applications requiring direct shell mounting without cable-side attachment points. Active product status and ROHS3 compliance confirmed.

Obsolete Alternative (Not Recommended for New Designs): 171-009-102L001 carries Obsolete product status and should not be selected for new designs or long-term production. This part is listed for reference only in legacy system documentation.

Temperature Range Consideration: All NorComp substitutes operate within -50°C to 100°C range, which is narrower than the original L717SDEG09PC309 specification (-55°C to 105°C). Substitution is valid only when application operating temperature remains within the -50°C to 100°C envelope.

Frequently Asked Questions (FAQ)

Q: Can 171-009-103L021 directly replace L717SDEG09PC309 in existing assemblies?

A: Electrical compatibility is confirmed across all 9 positions, signal contacts, and solder cup termination. Mechanical compatibility depends on mounting configuration. The original L717SDEG09PC309 uses free hanging (in-line) mounting with M3 cable-side flange, while 171-009-103L021 uses panel mount with 4-40 cable-side flange. Direct PCB-level substitution requires mechanical redesign of mounting brackets and cable attachment points.

Q: What is the significance of the higher 5A current rating on NorComp substitutes versus the 3A rating on the original?

A: The 5A rating on NorComp parts indicates higher current-carrying capacity per contact. For signal-level D-Sub applications (which this connector category represents), the 3A specification of the original part is typically sufficient. The higher NorComp rating does not create incompatibility; it provides additional design margin and is acceptable for direct electrical substitution in signal applications.

Q: Are there temperature range limitations when substituting with NorComp parts?

A: Yes. The original L717SDEG09PC309 operates from -55°C to 105°C. All NorComp substitutes (171-009-102L001, 171-009-103L001, 171-009-103L011, 171-009-103L021) operate from -50°C to 100°C. Substitution is valid only when the application's actual operating temperature remains within the narrower -50°C to 100°C range. Applications requiring the full -55°C to 105°C envelope must retain the original Amphenol ICC part.

Q: What is the difference between the flange features on different NorComp variants?

A: 171-009-103L001 features housing/shell unthreaded flange, suitable for direct panel mounting without external fasteners. 171-009-103L011 and 171-009-103L021 both feature cable-side 4-40 flanges, allowing threaded attachment to cable assemblies or external mounting structures. Selection depends on mechanical integration requirements in the target application.

Q: Why is 171-009-102L001 marked as Obsolete?

A: Obsolete status indicates the manufacturer (NorComp Inc.) has discontinued this part number. While inventory may remain available through distributors, long-term supply cannot be guaranteed. New designs should not incorporate obsolete parts. Use 171-009-103L001, 171-009-103L011, or 171-009-103L021 for current and future production.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original L717SDEG09PC309 is RoHS Compliant. All four NorComp substitutes are ROHS3 Compliant, which represents a more recent and stringent compliance standard. ROHS3 compliance includes RoHS compliance, ensuring environmental and hazardous substance restrictions are met or exceeded.

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

A: The original L717SDEG09PC309 uses steel with tin plating. NorComp substitutes use steel with nickel plating. Both finishes provide corrosion protection for signal-level applications. Nickel plating offers superior corrosion resistance in harsh environments and higher temperature stability. For standard industrial applications, both finishes are functionally equivalent.

Q: Can I use 171-009-103L021 in a free-hanging (in-line) cable assembly application?

A: 171-009-103L021 is designed for panel mount configuration. While the connector itself is electrically compatible, the mechanical design (panel mount flange vs. in-line free hanging) makes direct substitution in existing cable assemblies impractical without mechanical redesign. Consult mechanical design requirements before substitution.
