L77DFA15P D-Sub 15 Position Panel Mount Plug Connector

Part Overview

The L77DFA15P is a 15 position D-Sub plug connector with male pins, designed for panel mount applications. Manufactured by Amphenol ICC (Commercial Products), this connector features solder cup termination and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing system maintenance, repairs, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L77DFA15P is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 15
• Number of rows: 2
• Shell size and layout: 2 (DA, A)
• Termination method: Solder Cup
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• RoHS compliance status

Secondary Compatibility Parameters:

• Current rating: 7.5A minimum
• Voltage rating: 300V minimum
• Operating temperature range: Must encompass or exceed -55°C to 155°C
• Mounting type: Panel Mount (primary) or Free Hanging (limited compatibility)

Substitute parts are grouped into two categories: MFR Recommended (manufacturer-endorsed active alternatives) and Similar (functionally equivalent parts with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

L717DFA15P (MFR Recommended Substitute)

The L717DFA15P is the primary recommended substitute. This part is manufactured by Amphenol ICC (Commercial Products) and maintains active product status. It matches all critical parameters of the L77DFA15P including connector configuration, termination method, shell material, contact finish, current rating, and voltage rating. The operating temperature range is -55°C to 125°C, which is 30°C lower than the main part. This part is RoHS Compliant and carries MSL 1 rating. Selection of this part is appropriate for applications where the reduced upper temperature limit does not conflict with system requirements.

DAP15P065TXLF (Similar Substitute - Active Status)

The DAP15P065TXLF is an active product manufactured by Amphenol ICC (FCI) that provides functional equivalence with notable enhancements. This part maintains the 15 position, 2 row D-Sub configuration with solder cup termination and gold contact finish. Key differences include free hanging (in-line) mounting versus panel mount, higher voltage rating (1000V versus 300V), and enhanced contact finish thickness (30.0µin versus 20.0µin). Operating temperature range is -55°C to 125°C. This part is suitable for applications requiring higher voltage capability or where in-line mounting is acceptable. RoHS Compliant status is maintained.

172-015-102R001 (Similar Substitute - Obsolete Status)

The 172-015-102R001 is manufactured by NorComp Inc. and carries obsolete product status. While it maintains the core D-Sub 15 position configuration with panel mount and solder cup termination, it presents parameter limitations: current rating is 5A (versus 7.5A), voltage rating is not specified, and operating temperature range is -50°C to 100°C. Contact finish thickness is flash grade. This part is ROHS3 Compliant. Selection of this part is limited to legacy system maintenance where existing inventory exists and performance requirements align with reduced electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can L717DFA15P directly replace L77DFA15P in all applications?

A: L717DFA15P is the manufacturer-recommended substitute and maintains compatibility with the L77DFA15P for the majority of applications. The primary difference is the operating temperature upper limit: L717DFA15P operates to 125°C versus L77DFA15P at 155°C. Verify that your application does not require sustained operation above 125°C before selection.

Q: What is the difference between panel mount and free hanging mounting types?

A: Panel mount connectors (L77DFA15P, L717DFA15P, 172-015-102R001) are designed for installation through a panel with the connector body secured to the panel surface. Free hanging connectors (DAP15P065TXLF) are designed for in-line installation in cable assemblies without panel mounting. These mounting types are not interchangeable without mechanical redesign.

Q: Why does DAP15P065TXLF have a higher voltage rating (1000V) than the main part (300V)?

A: DAP15P065TXLF is from the DP series and is designed for higher voltage applications. The increased voltage rating reflects enhanced dielectric properties and internal spacing. This part can be used in applications requiring 300V operation, but the free hanging mounting type must be accommodated in the mechanical design.

Q: Is 172-015-102R001 suitable as a substitute despite its obsolete status?

A: 172-015-102R001 is obsolete and presents reduced electrical performance (5A current rating versus 7.5A, unspecified voltage rating, and limited temperature range to 100°C). This part is suitable only for legacy system maintenance where existing inventory is available and application requirements do not exceed its electrical specifications.

Q: What does contact finish thickness mean, and why does it vary?

A: Contact finish thickness refers to the plating layer applied to the contact surface. L77DFA15P and L717DFA15P both specify 20.0µin (0.51µm) gold plating. DAP15P065TXLF specifies 30.0µin (0.76µm), providing enhanced durability and wear resistance. 172-015-102R001 specifies flash plating, which is a minimal coating. Thicker plating generally provides longer contact life in high-cycle applications.

Q: Are all substitute parts RoHS compliant?

A: L77DFA15P, L717DFA15P, and DAP15P065TXLF are RoHS Compliant. 172-015-102R001 is ROHS3 Compliant. Both compliance levels meet current regulatory requirements. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use DAP15P065TXLF in a panel mount application?

A: DAP15P065TXLF is designed for free hanging (in-line) mounting and is not mechanically compatible with panel mount installations without custom adapter design. For panel mount applications, select L717DFA15P or 172-015-102R001.
