Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L717DCH37PCVF2 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for substitution eligibility:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 37
• Number of rows: 2
• Shell size, connector layout: 4 (DC, C)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Contact type: Signal
• Contact material: Brass
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• Dielectric material: Thermoplastic, Glass Filled or equivalent

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional compatibility:

• Manufacturer and part number
• Shell material finish (Tin Plated vs. Nickel Plated)
• Contact finish thickness (8.00µin vs. Flash)
• Current rating (7.5A vs. 5A)
• Voltage rating (300V vs. not specified)
• Operating temperature range (-55°C ~ 125°C vs. -50°C ~ 100°C)
• Backset spacing (0.319" vs. 0.283")
• Flange feature configuration
• Color
• RoHS compliance generation (RoHS Compliant vs. ROHS3 Compliant)
• Packaging format

The substitute parts 173-E37-113R001 and 173-E37-113R141 (both NorComp Inc.) meet all critical matching parameters and are therefore qualified as functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: L717DCH37PCVF2 (Amphenol ICC)

The L717DCH37PCVF2 is the specified component and should be used when available. This part is in active product status with established supply (854 units in stock). It provides the highest current rating (7.5A) and the widest operating temperature range (-55°C ~ 125°C), making it suitable for demanding applications. RoHS compliance and MSL 1 rating support unrestricted storage and handling.

Substitute Option 1: 173-E37-113R001 (NorComp Inc.)

This substitute is qualified for applications where the flange feature configuration permits housing/shell (unthreaded) mounting. The part meets all critical electrical and mechanical parameters. The reduced current rating (5A vs. 7.5A) and narrower operating temperature range (-50°C ~ 100°C) must be evaluated against application requirements. ROHS3 compliance and active product status support long-term availability. Backset spacing difference (0.283" vs. 0.319") requires PCB layout verification.

Substitute Option 2: 173-E37-113R141 (NorComp Inc.)

This substitute is qualified for applications requiring mating side female screwlock (4-40) configuration. The part includes mounting brackets as an additional feature. All critical electrical and mechanical parameters align with the primary part. The reduced current rating (5A vs. 7.5A) and narrower operating temperature range (-50°C ~ 100°C) must be evaluated against application requirements. ROHS3 compliance and active product status support long-term availability. Backset spacing difference (0.283" vs. 0.319") requires PCB layout verification.

Compliance Considerations:

All three parts are RoHS compliant (RoHS Compliant or ROHS3 Compliant) and carry UL94 V-0 flammability ratings. The substitute parts from NorComp Inc. are REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can 173-E37-113R001 or 173-E37-113R141 be used as direct replacements for L717DCH37PCVF2?

A: Both NorComp parts are functionally equivalent for 37-position D-Sub plug applications with solder termination and male pins. However, differences in current rating (5A vs. 7.5A), operating temperature range (-50°C ~ 100°C vs. -55°C ~ 125°C), backset spacing (0.283" vs. 0.319"), and flange feature configuration require application-specific evaluation. PCB layout and mounting requirements must be verified before substitution.

Q: What is the difference between 173-E37-113R001 and 173-E37-113R141?

A: Both parts are NorComp 37-position D-Sub plugs with identical electrical specifications. The primary difference is the flange feature: 173-E37-113R001 has housing/shell (unthreaded) mounting, while 173-E37-113R141 has mating side female screwlock (4-40) configuration and includes mounting brackets. Selection depends on the specific mounting and mating interface requirements of the application.

Q: Are there temperature or current limitations when substituting with NorComp parts?

A: Yes. The NorComp substitute parts (173-E37-113R001 and 173-E37-113R141) have a maximum current rating of 5A compared to 7.5A for the L717DCH37PCVF2. The operating temperature range is also narrower (-50°C ~ 100°C vs. -55°C ~ 125°C). Applications requiring the full 7.5A current capacity or extended temperature operation must use the primary Amphenol part or confirm that the reduced specifications are acceptable.

Q: What is the impact of backset spacing differences?

A: Backset spacing (0.319" for L717DCH37PCVF2 vs. 0.283" for NorComp parts) affects the distance from the connector mounting surface to the contact plane. This difference requires PCB layout verification to ensure proper component placement, clearance, and mating alignment. Mechanical drawings and assembly documentation must be reviewed before substitution.

Q: Are the shell material finishes interchangeable?

A: The L717DCH37PCVF2 uses tin-plated steel, while the NorComp substitutes use nickel-plated steel. Both finishes provide corrosion resistance and are suitable for signal applications. The choice between tin and nickel plating depends on environmental exposure, contact resistance requirements, and application-specific standards. No functional incompatibility exists for standard signal applications.

Q: What packaging formats are available?

A: The L717DCH37PCVF2 packaging format is not specified in the provided data. The NorComp substitute parts (173-E37-113R001 and 173-E37-113R141) are supplied in trays. Packaging format should be confirmed with the supplier based on procurement and assembly requirements.

Q: Are all parts RoHS compliant?

A: Yes. The L717DCH37PCVF2 is RoHS Compliant. The NorComp substitute parts (173-E37-113R001 and 173-E37-113R141) are ROHS3 Compliant. Both compliance levels meet current regulatory requirements. The NorComp parts are also REACH Unaffected.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: The L717DCH37PCVF2 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The NorComp substitute parts list MSL as Not Applicable, indicating they do not require moisture-controlled storage. Both approaches support standard handling and storage practices.
