L717DFB25PC Equivalent & Substitute Parts

Part Overview

The L717DFB25PC is a 25-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, through-hole solder connector features male pins and is designed for signal applications in industrial and commercial equipment. The connector is currently in active production status with 701 pieces available in inventory.

D-Sub connectors of this type are essential components in applications requiring standardized, reliable interconnection solutions. Substitute parts become necessary when specific mounting orientations, material specifications, or operational constraints differ from the original design requirements, or when supply chain considerations necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict alignment of core electrical and mechanical parameters. The following parameters must match or be compatible for a part to serve as a substitute:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (25)
• Number of rows (2)
• Shell size and layout (3 / DB, B)
• Contact type (Signal)
• Termination method (Solder)
• Contact material (Brass)
• Contact form (Machined)

Allowable Variations:

• Mounting orientation (panel mount configurations may include right-angle variants)
• Shell material finish (tin plated vs. nickel plated)
• Contact finish thickness (20.0µin vs. flash)
• Dielectric material composition (thermoplastic glass-filled vs. polyamide)
• Current rating (7.5A vs. 5A, where lower rating is acceptable for lower-demand applications)
• Operating temperature range (wider range preferred, narrower range acceptable for limited-temperature applications)
• Color (cosmetic variation)

The substitute part 173-E25-113R001 from NorComp Inc. meets all critical matching parameters and is therefore qualified as an equivalent substitute.

Engineering Selection Recommendations

L717DFB25PC Selection Criteria:

• Applications requiring straight-through panel mounting orientation
• Systems operating across extended temperature ranges (-55°C to 155°C)
• High-current applications up to 7.5A
• Designs specifying 300V voltage rating
• Environments with unlimited moisture exposure (MSL 1)
• Original equipment manufacturer (OEM) specifications calling for Amphenol ICC components

173-E25-113R001 Selection Criteria:

• Applications requiring right-angle connector orientation for space-constrained layouts
• Systems operating within -50°C to 100°C temperature range
• Applications with current requirements up to 5A
• Designs where nickel-plated shell finish is acceptable
• Environments where polyamide dielectric material meets performance requirements
• Supply chain scenarios where NorComp Inc. sourcing is preferred

Both parts maintain active product status and comply with RoHS and EAR99 export control classifications. The 173-E25-113R001 carries ROHS3 compliance, representing current regulatory alignment. Selection between these parts depends on specific mounting geometry requirements and operational temperature/current constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 173-E25-113R001 directly replace the L717DFB25PC in all applications?

A: The 173-E25-113R001 is electrically and mechanically compatible as a substitute for signal-level applications. However, the right-angle mounting orientation differs from the straight-through configuration of the L717DFB25PC. Applications requiring straight-through panel mounting must use the L717DFB25PC. Additionally, the 173-E25-113R001 has a lower current rating (5A vs. 7.5A) and narrower operating temperature range (-50°C to 100°C vs. -55°C to 155°C), which may limit suitability in high-current or extreme-temperature environments.

Q: What is the significance of the shell material finish difference (tin plated vs. nickel plated)?

A: Both tin and nickel plating provide corrosion resistance and electrical conductivity. Tin plating (L717DFB25PC) offers lower contact resistance and is commonly used in general-purpose applications. Nickel plating (173-E25-113R001) provides enhanced corrosion resistance in harsh environments. The choice depends on application environment and specific design requirements.

Q: Does the contact finish thickness difference affect performance?

A: The L717DFB25PC specifies 20.0µin (0.51µm) gold contact finish thickness, while the 173-E25-113R001 specifies flash thickness. Both provide adequate contact resistance and wear characteristics for signal-level applications. Flash plating is a minimal coating applied for corrosion prevention, while the thicker specification on the L717DFB25PC provides additional durability in high-cycle mating applications.

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

A: Both parts carry UL94 V-0 flammability ratings and RoHS compliance, indicating suitability for industrial and commercial applications. The L717DFB25PC offers extended operating temperature range and higher current capacity, making it more suitable for demanding high-reliability environments. The 173-E25-113R001 is suitable for standard commercial applications within its specified operating parameters.

Q: What packaging format is used for both parts?

A: Both the L717DFB25PC and 173-E25-113R001 are supplied in tray packaging, suitable for automated assembly processes and bulk component handling.

Q: Can these connectors be used interchangeably in PCB-mounted applications?

A: These connectors are specified for panel mounting with through-hole termination. They are not designed for direct PCB surface mounting. Both parts require panel cutout preparation and through-hole solder termination to the PCB or backplane.
