Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 172-015-102R021 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the main part specifications:

• Connector style: D-Sub (required match)
• Connector type: Plug with male pins (required match)
• Position count: 15 positions (required match)
• Row configuration: 2 rows (required match)
• Shell size and layout: 2 (DA, A) (required match)
• Mounting type: Panel mount (required match)
• Termination method: Solder cup (required match)
• Material flammability: UL94 V-0 minimum (required match)
• Contact material: Brass (required match)

Acceptable variations include shell material finish (tin-plated or nickel-plated), contact finish specifications, voltage rating (if higher), current rating (if equal or higher), and operating temperature range (if equal or wider). Dielectric material composition may vary provided UL94 V-0 compliance is maintained.

Parameter Comparison

Engineering Selection Recommendations

The 172-015-103R021 is the manufacturer-recommended substitute for the obsolete 172-015-102R021. Both parts are manufactured by NorComp Inc. within the same 172 M Series product line and maintain identical mechanical and electrical specifications. The primary difference is shell material finish (nickel-plated versus tin-plated), which does not affect functional compatibility. The 172-015-103R021 is currently in active production status with confirmed inventory availability.

The L777DFA15P, manufactured by Amphenol ICC, provides an alternative cross-reference option. This part maintains all critical mechanical parameters and connector geometry. The L777DFA15P offers enhanced current rating (7.5A versus 5A) and extended operating temperature range (-55°C ~ 125°C versus -50°C ~ 100°C), making it suitable for applications requiring higher thermal or current performance margins. The contact finish specification differs in thickness (30.0µin versus flash), and the flange feature configuration differs (housing/shell unthreaded versus cable side 4-40). Both parts maintain UL94 V-0 flammability compliance and RoHS certification.

Selection between 172-015-103R021 and L777DFA15P depends on application-specific requirements regarding current capacity, temperature extremes, and flange mounting configuration. Both are active production parts with confirmed inventory.

Frequently Asked Questions (FAQ)

Q: Can the 172-015-103R021 directly replace the obsolete 172-015-102R021?

A: Yes. Both parts are 15-position D-Sub plug connectors with identical pin counts, row configuration, shell size (2 DA/A), panel mount design, and solder cup termination. The nickel-plated shell finish of the 172-015-103R021 does not affect electrical or mechanical compatibility with the tin-plated original.

Q: What are the key differences between the NorComp 172-015-103R021 and the Amphenol L777DFA15P?

A: The primary differences are: current rating (5A versus 7.5A), operating temperature range (-50°C ~ 100°C versus -55°C ~ 125°C), flange feature configuration (cable side 4-40 versus housing/shell unthreaded), and contact finish thickness specification. All other critical parameters including connector type, position count, shell size, and termination method are identical.

Q: Are all three parts RoHS compliant?

A: Yes. The 172-015-102R021 and 172-015-103R021 are ROHS3 compliant. The L777DFA15P is RoHS compliant. All three parts meet applicable regulatory requirements.

Q: Which substitute should be selected for new designs?

A: The 172-015-103R021 is recommended as the primary substitute, as it is the manufacturer-recommended replacement within the same product series. The L777DFA15P is suitable when higher current capacity or extended temperature range is required by the application.

Q: Do these connectors require any special handling or storage considerations?

A: The 172-015-103R021 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. The L777DFA15P also has MSL 1 (Unlimited). Standard component storage practices are sufficient.

Q: What is the difference between flash gold plating and 30.0µin gold plating?

A: Flash gold plating is a very thin coating applied for corrosion protection and solderability. The 30.0µin (0.76µm) specification on the L777DFA15P provides a defined minimum thickness. Both finishes provide adequate contact protection for signal-level applications at the specified current ratings.
