Engineering Selection Recommendations

172-015-103R031 (NorComp Inc., MFR Recommended)

This part is the manufacturer-recommended substitute for the obsolete 172-015-102R031. Both parts share identical electrical and mechanical specifications, including 15-position configuration, panel mount design, and solder cup termination. The 172-015-103R031 maintains ROHS3 compliance and UL94 V-0 flammability rating. The primary difference is shell material finish (nickel plated versus tin plated) and dielectric material composition (Polyamide PA6T versus Polybutylene Terephthalate PBT). This part is currently in active production with confirmed inventory availability.

L777DFA15P (Amphenol ICC, Similar Alternative)

This Amphenol ICC connector provides functional equivalence with enhanced electrical performance characteristics. The L777DFA15P supports a higher current rating of 7.5A compared to the 5A rating of the original part, and offers an extended operating temperature range of -55°C ~ 125°C. The connector maintains the same 15-position D-Sub configuration, panel mount design, and solder cup termination. RoHS compliance and UL94 V-0 flammability rating are confirmed. This part is suitable for applications requiring higher current capacity or extended temperature operation within the same form factor.

Frequently Asked Questions (FAQ)

Q: Can the 172-015-103R031 be used as a direct replacement for the 172-015-102R031?

A: Yes. Both connectors share identical mechanical and electrical specifications for the core functional parameters: 15-position D-Sub plug configuration, panel mount design, solder cup termination, 5A current rating, and operating temperature range of -50°C ~ 100°C. The 172-015-103R031 is the manufacturer-recommended substitute.

Q: What are the differences between the 172-015-103R031 and L777DFA15P?

A: The primary differences are manufacturer (NorComp Inc. versus Amphenol ICC), shell material finish (nickel plated versus tin plated), current rating (5A versus 7.5A), and operating temperature range (-50°C ~ 100°C versus -55°C ~ 125°C). Both maintain D-Sub 15-position configuration and solder cup termination. The L777DFA15P is suitable for higher current or extended temperature applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 172-015-103R031 is ROHS3 compliant, and the L777DFA15P is RoHS compliant. Both meet current environmental compliance requirements.

Q: What is the significance of the shell material finish difference?

A: The 172-015-102R031 and L777DFA15P use tin plating, while the 172-015-103R031 uses nickel plating. Both finishes provide corrosion resistance and are suitable for standard industrial applications. Selection between them depends on specific environmental exposure and existing connector inventory compatibility.

Q: Can the L777DFA15P be used in applications with higher current requirements?

A: Yes. The L777DFA15P supports 7.5A current rating compared to the 5A rating of the original part. It is suitable for applications requiring higher current capacity while maintaining the same connector form factor and pin configuration.

Q: What packaging options are available for these substitute parts?

A: The 172-015-103R031 is supplied in tray packaging, while the L777DFA15P is supplied in bag packaging. Both are suitable for production assembly and repair applications.
