Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717SDCG37POL2RM5G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: D-Sub Plug with Male Pins
• Number of Positions: 37
• Number of Rows: 2
• Shell Size / Connector Layout: 4 (DC, C)
• Mounting Type: Through Hole
• Termination Method: Solder
• Contact Material: Brass
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Connector Style: D-Sub

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional compatibility:

• Voltage Rating: Substitute parts rated at 125V are acceptable for applications requiring 250V operation, as the lower rating represents a design constraint of the substitute, not a functional incompatibility
• Current Rating: Substitute parts rated at 6A exceed the 3A requirement and are acceptable
• Operating Temperature Range: Substitute parts with -55°C ~ 105°C range are acceptable for applications operating within this narrower band
• Shell Material Finish: Yellow Chromate Plated Zinc or Tin Plated finishes are acceptable alternatives
• Contact Finish Thickness: Flash or 30.0µin (0.76µm) are acceptable alternatives
• Dielectric Material: Thermoplastic Glass Filled, Polybutylene Terephthalate (PBT) Glass Filled, or Polyamide (PA) Nylon Glass Filled are acceptable alternatives
• Flange Feature: Board Side (M3) or Housing/Shell (Unthreaded) are acceptable alternatives
• Packaging: Tray, Bulk, or Tube are acceptable alternatives
• RoHS Status: Both RoHS Compliant and RoHS3 Compliant parts are acceptable; RoHS non-compliant parts require design review

Three substitute parts meet these criteria: TE Connectivity AMP Connectors 205714-7, 5205714-7, and 5745413-1.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: L717SDCG37POL2RM5G (Amphenol ICC)

The L717SDCG37POL2RM5G remains the primary component choice. This connector is Active product status, RoHS Compliant, and rated for 250V operation with -55°C ~ 125°C temperature range. The connector includes Board Lock and Grounding Indents features. Current inventory of 1005 units supports immediate procurement.

Secondary Selection: 5205714-7 (TE Connectivity AMP Connectors)

The 5205714-7 is the preferred substitute when L717SDCG37POL2RM5G availability is constrained. This part is RoHS Compliant, Active product status, and packaged in Tube format. The 6A current rating exceeds the 3A requirement. Operating temperature range is -55°C ~ 105°C, which is acceptable for applications not requiring the full 125°C upper limit. Inventory of 2240 units provides strong availability. The 125V voltage rating is a design constraint; applications requiring 250V operation must be evaluated for voltage margin requirements.

Tertiary Selection: 5745413-1 (TE Connectivity AMP Connectors)

The 5745413-1 is an acceptable substitute with ROHS3 Compliant status and Grounding Indents feature matching the primary part. Operating temperature range is -55°C ~ 105°C. Inventory of 1058 units is available. The 125V voltage rating applies the same constraint as 5205714-7.

Not Recommended: 205714-7 (TE Connectivity AMP Connectors)

The 205714-7 is RoHS Non-Compliant and does not meet RoHS requirements for new designs. This part is listed for reference only and should not be selected for new applications or designs requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can 5205714-7 or 5745413-1 be used in applications rated for 250V when these parts are only rated for 125V?

A: The 125V rating on substitute parts represents the maximum voltage specification for those components. Applications requiring 250V operation must verify that the substitute part's 125V rating provides adequate margin for the actual operating voltage. If the application circuit operates at or above 125V, the substitute parts are not suitable. Design review is required.

Q: What is the difference between the three TE Connectivity substitute parts?

A: The three TE Connectivity parts differ in packaging, RoHS status, and dielectric material. 5205714-7 is packaged in Tube with RoHS Compliant status and PBT dielectric. 5745413-1 is packaged in Tube with ROHS3 Compliant status and Polyamide dielectric, and includes Grounding Indents. 205714-7 is packaged in Bulk with RoHS Non-Compliant status. For new designs, 5205714-7 or 5745413-1 are preferred.

Q: Are the flange features interchangeable between Board Side (M3) and Housing/Shell (Unthreaded)?

A: The flange features differ in mechanical mounting configuration. Board Side (M3) uses M3 threaded mounting holes on the board. Housing/Shell (Unthreaded) uses unthreaded shell mounting. PCB layout and mechanical design must accommodate the specific flange feature. Verify board design compatibility before substitution.

Q: Does the difference in shell material finish (Tin Plated vs. Yellow Chromate Plated Zinc) affect electrical performance?

A: Both finishes provide corrosion protection and electrical conductivity. Tin Plated and Yellow Chromate Plated Zinc finishes are functionally equivalent for signal integrity. Environmental exposure conditions and specific application requirements may influence finish selection, but electrical performance is not affected.

Q: What is the significance of Contact Finish Thickness (Flash vs. 30.0µin)?

A: Both Flash and 30.0µin (0.76µm) gold finishes provide adequate contact surface for signal transmission. Flash plating is a thin, economical coating. 30.0µin represents a thicker gold layer. For standard signal applications, both are functionally equivalent. High-reliability or high-cycle mating applications may benefit from thicker plating, but this is not a substitution barrier for the specified parameters.

Q: Can the L717SDCG37POL2RM5G operate at the full -55°C ~ 125°C range if substituted with parts rated -55°C ~ 105°C?

A: Substitute parts rated -55°C ~ 105°C are limited to that temperature range. Applications requiring operation above 105°C must use the primary L717SDCG37POL2RM5G or equivalent parts rated to 125°C. Verify application temperature requirements before substitution.

Q: Is packaging format (Tray, Bulk, Tube) a factor in connector compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Packaging is a logistics and handling consideration. Tray, Bulk, and Tube formats contain identical connectors. Packaging selection is based on procurement quantity, storage, and handling requirements.
