Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717DB25PC with equivalent parts is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug with Male Pins
• Number of Positions: 25
• Shell Size, Connector Layout: 3 (DB, B)
• Termination Method: Solder
• Contact Type: Signal
• Flange Feature: Housing/Shell (Unthreaded)
• Contact Form: Machined
• Contact Material: Brass

Allowable Variation Parameters:

• Mounting Type: Through Hole configurations with Right Angle orientation
• Current Rating: Substitute parts must meet or exceed application requirements
• Voltage Rating: Substitute parts must meet or exceed application requirements
• Operating Temperature Range: Substitute parts must encompass application operating conditions
• Shell Material Finish: Alternative finishes acceptable if corrosion resistance requirements are met
• Contact Finish Thickness: Variations acceptable within industry standards
• Dielectric Material: Alternative thermoplastic materials acceptable if flammability rating maintained
• Color: Cosmetic variation, does not affect electrical function

The substitute part 173-E25-113R001 manufactured by NorComp Inc. qualifies as an equivalent based on matching all mandatory parameters and maintaining functional compatibility within specified electrical and environmental constraints.

Engineering Selection Recommendations

L717DB25PC Selection Criteria: The L717DB25PC is appropriate for applications requiring the full specified current rating of 7.5A and operating temperature range of -55°C to 125°C. This part is RoHS Compliant and maintains active production status. The tin-plated steel shell provides standard corrosion resistance for general industrial applications. Selection of this part is indicated when the extended temperature range and higher current capacity are required by the application specification.

173-E25-113R001 Selection Criteria: The 173-E25-113R001 is appropriate for applications operating within the -50°C to 100°C temperature range and requiring a maximum current rating of 5A. This part is ROHS3 Compliant and maintains active production status. The nickel-plated steel shell provides alternative corrosion resistance characteristics. The panel mount capability provides additional mounting flexibility. Selection of this part is indicated when the lower current and temperature specifications are sufficient for the application and when panel mount configuration is beneficial.

Compliance Considerations: Both parts maintain active product status and are compliant with current regulatory requirements (RoHS and REACH). Both parts feature UL94 V-0 flammability ratings and are suitable for applications requiring flame-resistant materials.

Frequently Asked Questions (FAQ)

Q: Can the 173-E25-113R001 be used as a direct replacement for the L717DB25PC?

A: The 173-E25-113R001 is functionally equivalent for applications operating within its specified current rating (5A maximum) and temperature range (-50°C to 100°C). Applications requiring the full 7.5A current capacity or extended temperature range (-55°C to 125°C) of the L717DB25PC require the original part or equivalent with matching specifications.

Q: What is the significance of the backset spacing difference between these parts?

A: The backset spacing differs between the two parts (L717DB25PC: 0.319" / 173-E25-113R001: 0.283"). This measurement affects the physical positioning of the connector on the printed circuit board. PCB layout and mechanical clearance requirements must accommodate the specific backset spacing of the selected part.

Q: Are the contact finish thicknesses interchangeable?

A: Both parts feature gold contact finish. The L717DB25PC specifies 8.00µin thickness while the 173-E25-113R001 specifies flash thickness. Both finishes provide electrical conductivity and corrosion resistance suitable for signal-level applications. Flash plating is a thinner application that reduces material cost while maintaining functional performance for standard signal transmission.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: The L717DB25PC features a tin-plated steel shell while the 173-E25-113R001 features a nickel-plated steel shell. Both finishes provide corrosion resistance for the steel substrate. Nickel plating offers enhanced corrosion resistance in harsh environments, while tin plating provides standard protection for general industrial applications. Selection depends on the specific environmental exposure conditions of the application.

Q: Do both parts support panel mount installation?

A: The L717DB25PC is specified for Through Hole and Right Angle mounting. The 173-E25-113R001 is specified for Panel Mount, Through Hole, and Right Angle mounting. The 173-E25-113R001 provides additional panel mount capability, making it suitable for applications requiring direct panel installation.

Q: Are both parts RoHS compliant?

A: Yes. The L717DB25PC is RoHS Compliant. The 173-E25-113R001 is ROHS3 Compliant. Both parts meet current RoHS requirements and are suitable for applications subject to RoHS regulations.

Q: What dielectric materials are used in each part?

A: The L717DB25PC uses Thermoplastic with Glass Filling as the dielectric material. The 173-E25-113R001 uses Polyamide (PA6T), specifically Nylon 6T. Both materials maintain UL94 V-0 flammability ratings and are suitable for applications requiring flame-resistant properties.
