Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L777DA15PC is determined by the following critical parameters that must match or remain compatible:

Mandatory Matching Parameters:

• Connector Type: D-Sub Plug with Male Pins
• Number of Positions: 15
• Number of Rows: 2
• Shell Size / Connector Layout: 2 (DA, A)
• Termination Method: Solder
• Mounting Type: Through Hole, Right Angle

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 7.5A requirement
• Voltage Rating: Substitute must meet or exceed 300V requirement
• Operating Temperature Range: Substitute must encompass or exceed -55°C to 125°C range
• Contact Finish: Gold plating acceptable; alternative finishes require compatibility verification
• Shell Material: Steel construction with alternative plating acceptable
• Flange Feature: Variations permitted if mechanical fit is maintained
• Compliance: RoHS and REACH compliance required

The substitute part 173-E15-113R141 (NorComp Inc.) meets the mandatory matching parameters for connector type, position count, row configuration, shell size, termination method, and right angle mounting. Variations in current rating, voltage rating, operating temperature, and shell finish are noted and documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L777DA15PC): The L777DA15PC remains the primary specification for applications requiring the full operating temperature range of -55°C to 125°C and current rating of 7.5A at 300V. This part is actively produced, RoHS compliant, and maintains REACH unaffected status. The tin-plated steel shell with glass-filled thermoplastic dielectric provides the specified performance envelope.

Substitute Part Selection (173-E15-113R141): The 173-E15-113R141 serves as an equivalent substitute where the following conditions are met:

• Application current requirement does not exceed 5A
• Operating temperature range requirement does not exceed -50°C to 100°C
• Backset spacing of 0.283" (7.20mm) is compatible with PCB layout
• Nickel-plated steel shell and polyamide dielectric are acceptable for the application
• Panel mount capability is beneficial or neutral to the design

Both parts maintain active production status, RoHS compliance, and REACH unaffected designation. Selection between these parts is determined by application-specific electrical and thermal requirements, not by compliance or availability factors.

Frequently Asked Questions (FAQ)

Q: Can the 173-E15-113R141 be used as a direct replacement for the L777DA15PC in all applications?

A: No. The 173-E15-113R141 has a lower current rating (5A versus 7.5A) and narrower operating temperature range (-50°C to 100°C versus -55°C to 125°C). Substitution is valid only when the application requirements fall within the substitute part's specifications. Additionally, backset spacing differs (0.283" versus 0.319"), requiring PCB layout verification.

Q: What is the significance of the different backset spacing values?

A: Backset spacing (0.319" for L777DA15PC and 0.283" for 173-E15-113R141) defines the distance from the mounting plane to the contact centerline. Different spacing values require verification against PCB footprint design. Mechanical fit and electrical performance depend on this parameter matching the PCB layout.

Q: Are the shell plating differences (tin versus nickel) significant for substitution?

A: Shell plating differences affect corrosion resistance and environmental performance. Tin plating (L777DA15PC) and nickel plating (173-E15-113R141) provide different protection characteristics. Selection depends on the application environment. Both materials are acceptable for standard industrial applications; specific environmental conditions may favor one over the other.

Q: What does the contact finish thickness specification mean?

A: Contact finish thickness (20.0µin for L777DA15PC, Flash for 173-E15-113R141) indicates the gold plating depth on the contact surfaces. Thicker plating generally provides enhanced durability and corrosion resistance. Flash plating is a minimal coating. Applications requiring extended contact life or harsh environments may benefit from the thicker plating of the primary part.

Q: Can I use the 173-E15-113R141 in a -55°C application?

A: No. The 173-E15-113R141 operating temperature range is -50°C to 100°C. Applications requiring operation at -55°C must use the L777DA15PC, which is rated to -55°C to 125°C.

Q: What is the difference between the dielectric materials used in these connectors?

A: The L777DA15PC uses thermoplastic with glass filling, while the 173-E15-113R141 uses polyamide (PA6T) nylon 6T. Both materials achieve UL94 V-0 flammability rating. Material selection affects mechanical properties, temperature stability, and environmental resistance. Both are suitable for standard D-Sub applications.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain active production status and full compliance certifications (RoHS, REACH). Selection for high-reliability applications depends on specific performance requirements. The L777DA15PC offers higher current capacity and wider temperature range, making it suitable for more demanding specifications. The 173-E15-113R141 is suitable for applications within its rated parameters.

Q: What does "Moisture Sensitivity Level (MSL)" indicate?

A: MSL 1 (L777DA15PC) indicates unlimited shelf life without moisture control requirements. The 173-E15-113R141 lists MSL as Not Applicable, indicating no moisture sensitivity concern. Both parts are suitable for standard storage and handling without special moisture control measures.
