L717SDCG37P Equivalent and Substitute Parts

Part Overview

The L717SDCG37P is a 37-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products), featuring male pins with solder cup termination. This connector is in active product status and is currently in stock with 715 pieces available. The need to identify equivalent and substitute parts arises from supply chain considerations, application-specific mounting requirements, and alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717SDCG37P with the NorComp 171-037-103L001 is evaluated on the basis of the following critical parameters:

Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 37
• Shell size and layout: 4 (DC, C)
• Termination method: Solder Cup
• Material flammability rating: UL94 V-0
• Contact type: Signal
• Grounding indents feature
• Color: Black
• RoHS compliance status (both compliant)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Differing Parameters:

• Mounting type: Free Hanging (In-Line) vs. Panel Mount
• Shell material finish: Steel, Tin Plated vs. Steel, Nickel Plated
• Contact material: Brass vs. Copper Alloy
• Current rating: 3A vs. 5A
• Operating temperature range: -55°C to 105°C vs. -50°C to 100°C
• Wire gauge: 20 AWG vs. 20-28 AWG
• Dielectric material: Thermoplastic, Glass Filled vs. Polybutylene Terephthalate (PBT), Glass Filled

The substitute part is compatible in applications where the mechanical mounting configuration permits panel mounting, temperature operating range does not require sub-50°C operation, and the higher current capacity (5A) meets or exceeds system requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the L717SDCG37P and 171-037-103L001 are active products with compliant certifications (RoHS/ROHS3) and identical Moisture Sensitivity Levels, making either suitable for standard applications. Selection depends on the following application-specific factors:

The L717SDCG37P is appropriate for in-line cable assemblies requiring free-hanging connector configuration and extended low-temperature operation down to -55°C. Its tin-plated steel shell and brass contact material provide specified compatibility for 3A current at 250V.

The 171-037-103L001 is appropriate for panel-mounted installations where the connector is secured to an enclosure. Its higher current rating (5A) accommodates applications with elevated current demands. However, the specified operating temperature range (-50°C to 100°C) excludes applications requiring operation below -50°C.

Both connectors comply with UL94 V-0 flammability standards and feature identical D-Sub geometry, positioning, and solder cup termination, ensuring mechanical and electrical interface compatibility within their respective operational envelopes.

Frequently Asked Questions (FAQ)

Q: Can the 171-037-103L001 (NorComp) substitute for the L717SDCG37P (Amphenol ICC) in all applications?

A: No. Substitution is contingent upon three conditions: (1) the application permits panel mounting rather than requiring free-hanging in-line configuration; (2) the system operates within the temperature range of -50°C to 100°C (not below -50°C); and (3) the circuit current does not exceed the Amphenol connector's 3A rating, or the application can tolerate the NorComp connector's 5A capacity.

Q: What is the functional difference between the mounting types?

A: The L717SDCG37P (free hanging, in-line) is designed for direct cable attachment without mechanical fastening to an enclosure. The 171-037-103L001 (panel mount) is designed for fastening through a panel opening, providing mechanical retention and alignment. These mounting types are not interchangeable in physical layout.

Q: Are the shell materials compatible in terms of shielding and durability?

A: Both connectors use steel shells with plating. The L717SDCG37P employs tin plating; the 171-037-103L001 employs nickel plating. Both finishes provide corrosion resistance and maintain the electromagnetic shielding properties inherent to the D-Sub shell design. Selection depends on environmental exposure and existing fleet requirements.

Q: What is the significance of the wire gauge difference (20 AWG vs. 20-28 AWG)?

A: The L717SDCG37P specifies 20 AWG wire gauge for solder cup termination. The 171-037-103L001 accommodates a broader range (20-28 AWG). This means the NorComp connector provides greater flexibility in cable gauge selection without compromising termination integrity, though both are suitable for standard D-Sub applications.

Q: Do both connectors support the same signal types?

A: Yes. Both connectors are classified as signal contacts with identical position count (37) and shell geometry (size 4, DC/C layout). The functional signal architecture is identical.

Q: What compliance certifications apply to each connector?

A: The L717SDCG37P is RoHS Compliant. The 171-037-103L001 is ROHS3 Compliant. Both standards restrict hazardous substances; ROHS3 represents an updated regulatory framework. Both parts have Moisture Sensitivity Level 1 (Unlimited handling storage requirements). Both connectors carry UL94 V-0 flammability ratings and are assigned ECCN EAR99 classification with HTSUS code 8536.69.8000.
