Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717DFC37PC is permitted with equivalent parts that maintain the following critical parameters:

Mandatory Matching Parameters:

• Connector type: D-Sub Plug with male pins
• Position count: 37 positions
• Row configuration: 2 rows
• Shell size: 4 (DC, C)
• Mounting configuration: Panel mount, through-hole, right-angle orientation
• Termination: Solder
• Contact type: Signal
• Flange feature: Housing/Shell (Unthreaded)
• Contact material: Brass with gold finish
• Flammability rating: UL94 V-0

Parameters Permitting Variation:

• Current rating: Substitute parts rated at 5A are acceptable for applications not exceeding 5A
• Voltage rating: Substitute parts without specified voltage rating are acceptable for signal-level applications
• Operating temperature range: Substitute parts with -50°C to 100°C range are acceptable for applications within this narrower band
• Shell material finish: Nickel plating is acceptable as alternative to tin plating
• Contact finish thickness: Flash coating is acceptable as alternative to 20.0µin specification
• Backset spacing: Variation from 0.319" to 0.283" is acceptable within connector design tolerances
• Dielectric material: Polyamide (PA6T) Nylon 6T is acceptable alternative to thermoplastic glass-filled material
• Flange configuration: Female screwlock mating side feature is acceptable addition

The identified substitute parts (173-E37-113R001 and 173-E37-113R141) from NorComp Inc. meet all mandatory matching parameters and are therefore electrically and mechanically compatible for direct substitution in applications operating within the narrower environmental and electrical specifications of the substitute parts.

Parameter Comparison

Engineering Selection Recommendations

L717DFC37PC (Amphenol ICC DF Series): Select this part for applications requiring the full specified operating temperature range (-55°C to 155°C), maximum current rating of 7.5A, and 300V voltage rating. This connector is suitable for industrial environments with extended temperature requirements and higher power signal applications. RoHS compliance and UL94 V-0 flammability rating are confirmed.

173-E37-113R001 (NorComp 173-E M Series): Select this part for applications operating within -50°C to 100°C temperature range and maximum 5A current requirements. This connector provides equivalent mechanical and electrical compatibility for standard signal-level applications. ROHS3 compliance and UL94 V-0 flammability rating are confirmed. Nickel-plated steel shell provides corrosion resistance alternative to tin plating. Suitable for commercial and industrial environments within specified temperature and current limits.

173-E37-113R141 (NorComp 173-E M Series with Screwlock): Select this part for applications requiring the same electrical and mechanical specifications as 173-E37-113R001 with the addition of female screwlock mating side feature (4-40) and mounting brackets. This configuration provides enhanced mechanical retention and simplified panel mounting. Operating within -50°C to 100°C temperature range and 5A maximum current. ROHS3 compliance and UL94 V-0 flammability rating are confirmed.

All three parts are active products with confirmed inventory availability and meet applicable regulatory compliance standards for their respective specifications.

Frequently Asked Questions (FAQ)

Q: Can the L717DFC37PC be directly replaced with 173-E37-113R001 or 173-E37-113R141?

A: Direct substitution is permitted when the application operates within the narrower specifications of the NorComp parts. The substitute parts maintain identical connector type, position count, row configuration, shell size, mounting orientation, and termination method. Substitution is valid for applications not exceeding 5A current and operating within -50°C to 100°C temperature range. Applications requiring the full 7.5A rating, 300V voltage specification, or -55°C to 155°C temperature range must use the L717DFC37PC.

Q: What are the differences in shell material finish between these connectors?

A: The L717DFC37PC features a tin-plated steel shell, while both NorComp substitute parts feature nickel-plated steel shells. Both finishes provide corrosion resistance and are suitable for standard industrial environments. Nickel plating offers enhanced corrosion resistance in certain chemical environments compared to tin plating.

Q: Does the female screwlock feature on 173-E37-113R141 affect compatibility?

A: The female screwlock (4-40) mating side feature on 173-E37-113R141 is an addition that does not affect electrical or mechanical compatibility with standard D-Sub receptacles. This feature provides enhanced mechanical retention during mating and is compatible with standard D-Sub plug connectors. The mounting brackets on this variant simplify panel installation.

Q: Are there temperature limitations when substituting these parts?

A: Yes. The L717DFC37PC operates from -55°C to 155°C, while both NorComp substitute parts operate from -50°C to 100°C. Applications requiring operation below -50°C or above 100°C must use the L717DFC37PC. Applications within the -50°C to 100°C range may use either part.

Q: What is the significance of the contact finish thickness difference?

A: The L717DFC37PC specifies 20.0µin (0.51µm) gold contact finish thickness, while the NorComp parts specify flash gold coating. Flash coating provides adequate contact resistance and durability for signal-level applications. The thicker specification on the L717DFC37PC may provide extended contact life in high-cycle mating applications, but both finishes are suitable for standard industrial signal applications.

Q: Are all three parts RoHS compliant?

A: Yes. The L717DFC37PC is RoHS Compliant. Both NorComp parts (173-E37-113R001 and 173-E37-113R141) are ROHS3 Compliant. All three parts meet applicable RoHS requirements for their respective compliance standards.

Q: What is the difference in backset spacing between these connectors?

A: The L717DFC37PC has 0.319" (8.10mm) backset spacing, while both NorComp parts have 0.283" (7.20mm) backset spacing. This variation is within connector design tolerances and does not affect mechanical or electrical compatibility. Backset spacing refers to the distance from the mating face to the rear of the connector housing.

Q: Can these connectors be used interchangeably in existing designs?

A: Interchangeability depends on application specifications. For applications designed for the L717DFC37PC operating at 7.5A, 300V, or -55°C to 155°C, the NorComp substitutes are not interchangeable. For applications designed within the NorComp specifications (5A maximum, -50°C to 100°C), either NorComp part is interchangeable with the other, with 173-E37-113R141 providing additional screwlock and bracket features.
