Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connectors is determined by strict alignment of the following parameters:

Critical Parameters (Must Match):

• Connector type: Plug with male pins
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Termination method: Solder cup
• Contact finish: Gold
• Material flammability rating: UL94 V-0

Allowable Variations:

• Mounting type (free-hanging vs. panel mount) may differ based on application context
• Shell material finish (tin plated vs. nickel plated) is acceptable when both provide corrosion resistance
• Current rating may exceed the minimum requirement (3A baseline)
• Operating temperature range may be narrower if minimum requirements are met
• Dielectric material composition (thermoplastic glass-filled vs. polybutylene terephthalate glass-filled) is acceptable when both meet flammability standards
• Wire gauge range flexibility (20 AWG vs. 20-28 AWG) accommodates different conductor sizes
• Contact material (brass vs. copper alloy) is acceptable when both support gold plating and electrical performance

The substitute part 171-037-103L001 meets these criteria and qualifies as an equivalent component.

Parameter Comparison

Engineering Selection Recommendations

L717SDC37PVFMC309 (Amphenol ICC) Selection Criteria:

• Higher current rating (5A) exceeds the 3A baseline, providing additional capacity margin
• ROHS3 Compliant status reflects updated regulatory compliance framework
• 1162 units in inventory provide alternative sourcing with higher stock levels
• Nickel-plated steel shell offers equivalent corrosion resistance to tin-plated finish
• PBT dielectric material provides alternative thermoplastic composition meeting UL94 V-0 requirements

Both parts maintain Active product status, MSL Level 1 (Unlimited), and identical ECCN/HTSUS classifications, confirming regulatory and export compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the 171-037-103L001 replace the L717SDC37PVFMC309 in a free-hanging in-line application?

A: The 171-037-103L001 is designed for panel mount configuration. While the electrical and mechanical parameters align (37 positions, shell size 4, solder cup termination, gold contact finish, UL94 V-0), the mounting type difference requires mechanical integration assessment. Application-specific mounting requirements must be evaluated before substitution.

Q: What is the significance of the contact finish thickness difference (30.0µin vs. Flash)?

A: Both finishes provide gold plating for signal integrity and corrosion resistance. The L717SDC37PVFMC309 specifies 30.0µin (0.76µm) thickness, while the 171-037-103L001 uses flash plating. Flash plating is a thin, economical coating suitable for signal applications. Selection depends on application durability and environmental exposure requirements.

Q: Are the dielectric materials interchangeable?

A: Both materials are glass-filled thermoplastics meeting UL94 V-0 flammability requirements. The L717SDC37PVFMC309 uses thermoplastic (unspecified resin), while the 171-037-103L001 uses polybutylene terephthalate (PBT). Both compositions provide equivalent electrical insulation and mechanical stability for D-Sub connector applications.

Q: Does the wire gauge range difference affect compatibility?

A: The L717SDC37PVFMC309 specifies 20 AWG, while the 171-037-103L001 accommodates 20-28 AWG. The 171-037-103L001 offers broader conductor size compatibility. If your application uses 20 AWG conductors, both parts are compatible. If smaller gauges (22-28 AWG) are required, only the 171-037-103L001 supports this range.

Q: What is the impact of the operating temperature range difference?

A: The L717SDC37PVFMC309 operates from -55°C to 105°C, while the 171-037-103L001 operates from -50°C to 100°C. The L717SDC37PVFMC309 provides 5°C lower minimum and 5°C higher maximum temperature capability. For applications requiring extreme cold (-55°C) or high heat (105°C), the L717SDC37PVFMC309 is the specified choice.

Q: How do the current ratings affect part selection?

A: The L717SDC37PVFMC309 is rated for 3A, while the 171-037-103L001 is rated for 5A. Both ratings apply per contact. If your application requires 3A or less per contact, both parts are suitable. The 171-037-103L001 provides additional current capacity margin for higher-power signal applications.

Q: Are both parts RoHS compliant?

A: Yes. The L717SDC37PVFMC309 is RoHS Compliant, and the 171-037-103L001 is ROHS3 Compliant. Both meet lead-free and hazardous substance restrictions. ROHS3 represents the updated regulatory framework. Both parts satisfy current environmental compliance requirements.
