Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFCF37P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: D-Sub Plug with Male Pins
• Number of Positions: 37
• Number of Rows: 2
• Shell Size / Connector Layout: 4 (DC, C)
• Mounting Type: Panel Mount
• Termination Method: Solder Cup
• Flange Feature: Housing/Shell (Unthreaded)
• Contact Type: Signal

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 Thickness: Flash or thicker finishes are acceptable
• Shell Material Finish: Steel with tin plating is standard; equivalent finishes acceptable
• Dielectric Material: Thermoplastic or polyester-based glass-filled materials acceptable
• Color: Functional equivalence; does not affect electrical performance
• Packaging Format: Bag or tray packaging does not affect connector function

The substitute part 172-037-102R001 manufactured by NorComp Inc. meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Engineering Selection Recommendations

Primary Selection: L717DFCF37P (Amphenol ICC)

The L717DFCF37P is the recommended primary choice for new designs and applications. This connector is in active production status, ensuring long-term availability and supply chain stability. The part meets all specified electrical and mechanical requirements with a current rating of 7.5A, voltage rating of 300V, and operating temperature range of -55°C to 125°C. RoHS compliance and MSL Level 1 (unlimited moisture sensitivity) provide environmental and handling flexibility. Gold contact finish at 20.0µin thickness ensures reliable signal transmission and corrosion resistance.

Secondary Selection: 172-037-102R001 (NorComp Inc.)

The 172-037-102R001 is classified as an obsolete product and should be considered only when the primary part is unavailable and application requirements permit reduced electrical specifications. This substitute exhibits the following limitations:

• Current Rating: 5A (below the 7.5A specification of the primary part)
• Operating Temperature Range: -50°C to 100°C (narrower than the -55°C to 125°C range of the primary part)
• Voltage Rating: Not specified in available documentation
• Product Status: Obsolete (no guarantee of future availability)

The 172-037-102R001 maintains mechanical and connector layout equivalence and shares RoHS compliance status. Applications operating within the reduced current and temperature specifications may utilize this substitute when supply constraints necessitate alternative sourcing. However, applications requiring the full 7.5A current capacity or extended temperature operation must use the primary L717DFCF37P connector.

Frequently Asked Questions (FAQ)

Q: Can the 172-037-102R001 be used as a direct replacement for the L717DFCF37P in all applications?

A: No. While both connectors share identical mechanical and layout specifications, the 172-037-102R001 has a reduced current rating of 5A compared to the L717DFCF37P's 7.5A rating. Applications requiring the full 7.5A capacity must use the primary part. Additionally, the substitute's operating temperature range (-50°C to 100°C) is narrower than the primary part's range (-55°C to 125°C).

Q: What is the significance of the "Obsolete" product status for the 172-037-102R001?

A: Obsolete status indicates that NorComp Inc. has discontinued production of this connector. While current inventory may be available (1034 pieces noted), future availability is not guaranteed. New designs should specify the active L717DFCF37P to ensure long-term supply chain viability.

Q: Are the packaging differences (Bag vs. Tray) functionally significant?

A: No. Packaging format does not affect connector electrical or mechanical performance. The choice between bag and tray packaging is a logistics and handling consideration only. Both formats protect the connector during storage and transport.

Q: How do the contact finish specifications compare between these connectors?

A: Both connectors feature gold plating on brass contacts. The L717DFCF37P specifies 20.0µin (0.51µm) thickness, while the 172-037-102R001 specifies flash plating. Flash plating provides a thin gold layer sufficient for signal transmission and corrosion protection in most applications. The thicker 20.0µin specification of the primary part offers enhanced durability for high-cycle mating applications.

Q: What does RoHS3 compliance mean for the 172-037-102R001?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive 3, the current version of the RoHS regulation. This is equivalent to or more stringent than standard RoHS compliance. Both connectors meet environmental regulatory requirements for hazardous substance restriction.

Q: Can I use the 172-037-102R001 in applications with temperature extremes?

A: The 172-037-102R001 is rated for -50°C to 100°C operation. Applications requiring operation below -50°C or above 100°C must use the L717DFCF37P, which is rated for -55°C to 125°C. Exceeding the rated temperature range may result in dielectric material degradation or contact reliability issues.

Q: Are there any compliance or certification differences between these parts?

A: Both connectors are RoHS compliant and carry EAR99 ECCN classification. The L717DFCF37P has MSL Level 1 (unlimited moisture sensitivity), while the 172-037-102R001 lists MSL as Not Applicable. Both share the same HTSUS code (8536.69.8000) and UL94 V-0 flammability rating.
