Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L17TF3710102 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Mounting type: Through hole
• Termination method: Press-fit
• Shell material and finish: Steel, tin plated
• Contact finish: Gold
• Flammability rating: UL94 V-0
• Grounding indents feature presence
• Contact type: Signal
• MSL rating: 1 (Unlimited)

The substitute part 5788458-1 manufactured by TE Connectivity AMP Connectors meets all mandatory matching parameters. Both connectors share identical mechanical interfaces, electrical signal handling capabilities, and environmental compliance ratings. The parts are functionally interchangeable within applications requiring 37-position D-Sub plug connectors with press-fit termination and through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Both L17TF3710102 and 5788458-1 are active production parts with full regulatory compliance. The L17TF3710102 carries RoHS Compliant certification, while the 5788458-1 carries ROHS3 Compliant certification, indicating both meet current environmental standards.

Selection Criteria:

The L17TF3710102 features a mating-side female screwlock flange (4-40), providing threaded fastening capability at the mating interface. The 5788458-1 features an unthreaded housing/shell flange, offering a simplified mechanical interface without threaded engagement.

Applications requiring threaded mating-side fastening should specify the L17TF3710102. Applications where unthreaded shell flanges are acceptable or preferred may utilize the 5788458-1.

Both parts are suitable for applications operating within -55°C to 125°C temperature ranges and support signal-level electrical connections. Inventory availability differs between manufacturers: L17TF3710102 has 671 units in stock (tray packaging), while 5788458-1 has 709 units in stock (bulk packaging).

Frequently Asked Questions (FAQ)

Q: Are L17TF3710102 and 5788458-1 mechanically interchangeable?

A: Both connectors share identical shell size (4/DC/C), pin count (37), row configuration (2), and through-hole mounting specifications. The primary mechanical difference is the flange design: L17TF3710102 includes a threaded female screwlock (4-40) on the mating side, while 5788458-1 features an unthreaded housing shell. Interchangeability depends on whether the application requires threaded mating-side fastening.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: PCB footprints designed for the L17TF3710102 will accommodate the 5788458-1 if the unthreaded flange design is compatible with the application's mechanical requirements. If the design specifically incorporates threaded fastening holes for the 4-40 screwlock, the 5788458-1 cannot be used without mechanical redesign.

Q: What are the electrical differences between these parts?

A: Both connectors feature gold-plated contacts, signal-level contact type, and UL94 V-0 flammability ratings. Electrical performance characteristics are equivalent for signal transmission applications.

Q: How do packaging differences affect part selection?

A: L17TF3710102 is supplied in tray packaging (671 units available), while 5788458-1 is supplied in bulk packaging (709 units available). Packaging selection depends on procurement volume requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes. L17TF3710102 is RoHS Compliant, and 5788458-1 is ROHS3 Compliant. Both meet current environmental regulatory requirements for electronic component manufacturing and use.

Q: What is the operating temperature range for these connectors?

A: The L17TF3710102 operates from -55°C to 125°C. Operating temperature specifications for the 5788458-1 were not provided in the available technical data.

Q: Do these connectors support the same current ratings?

A: The L17TF3710102 is rated for 3A per contact. Current rating specifications for the 5788458-1 were not provided in the available technical data.
