Frequently Asked Questions (FAQ)

Q: Can the 5788458-1 be used as a direct replacement for the L17TF3710115 in existing designs?

A: Yes. Both connectors are 37-position D-Sub plugs with identical electrical ratings (300V, 3A), mechanical specifications (through-hole press-fit mounting, shell size 4), and regulatory compliance (RoHS, UL94 V-0). The connectors are mechanically and electrically interchangeable.

Q: What are the key differences between these two connector models?

A: The primary differences are manufacturer identity and packaging format. The L17TF3710115 is supplied by Amphenol ICC in tray packaging, while the 5788458-1 is supplied by TE Connectivity in bulk packaging. Both maintain identical electrical performance, mechanical compatibility, and regulatory certifications.

Q: Are there any compatibility concerns with PCB footprints or mating connectors?

A: Both connectors conform to the same D-Sub shell size 4 (DC, C) specification with 37 positions in a 2-row configuration. PCB footprints and mating receptacles designed for one connector are compatible with the other.

Q: What is the significance of the contact finish specifications?

A: Both connectors feature gold-plated contacts, which provide superior corrosion resistance and electrical conductivity compared to unplated or nickel-plated alternatives. This specification is critical for reliable signal transmission in applications requiring consistent contact resistance over extended operational life.

Q: How do the operating temperature ranges compare?

A: Both connectors operate across the identical temperature range of -55°C to 125°C, ensuring consistent performance in thermal cycling applications and extreme environmental conditions.

Q: What does RoHS compliance mean for these connectors?

A: Both connectors comply with Restriction of Hazardous Substances regulations. The L17TF3710115 carries RoHS Compliant status, while the 5788458-1 carries ROHS3 Compliant status. Both designations confirm the absence of restricted substances including lead, cadmium, and hexavalent chromium.

Q: Are these connectors suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity level (MSL 1), indicating suitability for industrial and commercial applications. The press-fit termination method provides secure mechanical retention without solder joints.

Q: What is the difference between tray and bulk packaging?

A: Tray packaging (L17TF3710115) organizes components in individual compartments for automated assembly and reduced handling. Bulk packaging (5788458-1) supplies components in loose form, suitable for manual assembly or high-volume automated processes with component feeders.
