Frequently Asked Questions (FAQ)

Q: Can the 5788458-1 be used as a direct replacement for the L17TF3710100 in existing designs?

A: Yes. Both connectors share identical electrical specifications (37 positions, 2 rows, Size 4 shell layout, 3A current rating, 300V voltage rating), mechanical specifications (through-hole mounting, press-fit termination, unthreaded housing), and environmental ratings (UL94 V-0, -55°C to 125°C operating range). Direct substitution is supported without design modification.

Q: Are there differences in contact material between these parts?

A: The L17TF3710100 specifies brass contact material with gold finish (flash thickness). The 5788458-1 specifies copper alloy contact material with gold finish. Both materials with gold plating provide equivalent electrical conductivity and signal integrity for D-Sub applications.

Q: What is the difference between the packaging formats?

A: The L17TF3710100 is supplied in Tray packaging, while the 5788458-1 is supplied in Bulk packaging. Tray packaging typically provides organized component presentation and handling protection. Bulk packaging is suitable for high-volume assembly operations. Packaging format does not affect connector performance or compatibility.

Q: Do both parts meet current RoHS requirements?

A: Yes. The L17TF3710100 is RoHS Compliant. The 5788458-1 is ROHS3 Compliant. Both certifications meet current regulatory standards for restricted substances in electrical and electronic equipment.

Q: Are the operating temperature ranges identical?

A: The L17TF3710100 specifies an operating temperature range of -55°C to 125°C. The 5788458-1 does not specify an operating temperature range in the provided data. For applications requiring confirmed temperature specifications, the L17TF3710100 provides explicit temperature rating documentation.

Q: What is the significance of the grounding indents feature?

A: Both connectors include grounding indents as a standard feature. This design element provides mechanical alignment and electrical grounding continuity between mated connector pairs, ensuring reliable signal integrity and EMI shielding in D-Sub applications.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes. Both connectors have identical through-hole mounting specifications and press-fit termination requirements. PCB footprints designed for the L17TF3710100 accommodate the 5788458-1 without modification, provided the PCB layout follows standard D-Sub Size 4 specifications.
