Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle connectors is determined by strict alignment of the following critical parameters:

Position and Configuration Match:

• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)

Electrical Compatibility:

• Connector type: Receptacle, Female Sockets
• Termination method: IDC, Ribbon Cable
• Contact finish: Gold plating
• Operating temperature range: -55°C ~ 105°C

Mechanical and Material Specifications:

• Shell material and finish: Steel, Tin Plated
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Regulatory Compliance:

• RoHS compliance status
• ECCN classification: EAR99

The substitute part 8337-6009 (3M) satisfies all core substitution criteria with the following exceptions: mounting type differs (panel mount versus free-hanging), current rating is reduced (1A versus 3A), voltage rating is not specified, and contact material composition differs (copper alloy versus brass). These differences establish application-specific constraints that must be evaluated during component selection.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L17DCFRDA37SC309):

The Amphenol ICC L17DCFRDA37SC309 maintains active product status with established RoHS compliance and UL94 V-0 flammability certification. This connector is specified for applications requiring 3A current capacity and 250V voltage rating with free-hanging, in-line mounting configuration. The part supports 26 AWG wire gauge specification with brass contact material and thermoplastic dielectric composition.

Substitute Part Evaluation (8337-6009):

The 3M 8337-6009 provides functional equivalence for 37-position D-Sub receptacle applications with identical position count, row configuration, and shell size. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity classification. However, the 3M substitute introduces the following constraints:

• Mounting Configuration: Panel mount versus free-hanging in-line. This difference requires mechanical redesign of the connector interface and is not interchangeable without board-level modifications.
• Current Rating: 1A maximum versus 3A. Applications requiring current transmission above 1A per contact cannot use the 3M substitute without exceeding electrical specifications.
• Voltage Rating: Not specified for the 3M part, whereas the Amphenol ICC part is rated for 250V. Voltage compatibility must be independently verified for the 3M connector.
• Contact Material: Copper alloy versus brass. Different contact material composition may affect contact resistance and long-term reliability characteristics.
• Dielectric Material: PBT polyester versus thermoplastic. Different polymer formulations may exhibit different thermal and mechanical properties.

Selection Criteria:

Use the L17DCFRDA37SC309 for applications requiring 3A current capacity, 250V voltage rating, and free-hanging in-line mounting. Use the 8337-6009 only when panel mount configuration is required, current demand does not exceed 1A per contact, and voltage requirements are compatible with unspecified ratings. Both parts satisfy RoHS compliance and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 8337-6009 directly replace the Amphenol ICC L17DCFRDA37SC309 in existing designs?

A: Direct replacement is not possible without design modification. The 3M part features panel mount configuration while the Amphenol ICC part is free-hanging in-line. Mechanical interface redesign is required. Additionally, the 3M part is rated for 1A maximum current versus 3A for the Amphenol ICC part. Verify that your application current requirements do not exceed 1A per contact before considering substitution.

Q: What are the critical parameters that must match for D-Sub 37-position receptacle substitution?

A: The following parameters must match exactly: connector style (D-Sub), connector type (receptacle, female sockets), number of positions (37), number of rows (2), shell size and layout (4, DC, C), and termination method (IDC, ribbon cable). Differences in mounting type, current rating, voltage rating, contact material, or dielectric material composition establish application-specific constraints that must be evaluated independently.

Q: Are both connectors RoHS compliant?

A: Yes. The Amphenol ICC L17DCFRDA37SC309 is RoHS Compliant. The 3M 8337-6009 is ROHS3 Compliant. Both meet RoHS regulatory requirements, though they reference different versions of the RoHS directive.

Q: What is the difference in packaging between these two parts?

A: The Amphenol ICC L17DCFRDA37SC309 is supplied in tray packaging with 950 units in current inventory. The 3M 8337-6009 is supplied in bulk packaging with 1234 units in current inventory. Packaging format affects handling, storage, and component placement procedures in manufacturing environments.

Q: Can I use the 3M 8337-6009 in a high-current application requiring 3A per contact?

A: No. The 3M 8337-6009 is rated for 1A maximum current per contact. Using this connector in applications requiring 3A per contact exceeds the electrical specifications and may result in connector failure, contact degradation, or fire hazard. The Amphenol ICC L17DCFRDA37SC309 is rated for 3A and is the appropriate choice for high-current applications.

Q: What is the operating temperature range for both connectors?

A: Both the Amphenol ICC L17DCFRDA37SC309 and the 3M 8337-6009 operate across the temperature range of -55°C to 105°C. This specification matches for both parts and supports applications requiring extended temperature operation.

Q: Are there differences in contact material between these connectors?

A: Yes. The Amphenol ICC L17DCFRDA37SC309 uses brass contact material. The 3M 8337-6009 uses copper alloy contact material. Both contacts are finished with 30.0µin (0.76µm) gold plating. Different base contact materials may exhibit different contact resistance, corrosion resistance, and long-term reliability characteristics depending on application environment and signal frequency.

Q: What does the shell size designation "4 (DC, C)" mean?

A: Shell size 4 refers to the physical dimensions of the D-Sub connector housing. The designation (DC, C) specifies the connector layout configuration. Both the Amphenol ICC and 3M connectors use identical shell size and layout, ensuring mechanical compatibility for the connector interface itself, though mounting method differences remain.

Q: Is the voltage rating specified for the 3M 8337-6009?

A: No. The 3M 8337-6009 does not have a specified voltage rating in the provided data. The Amphenol ICC L17DCFRDA37SC309 is rated for 250V. If your application requires a specified voltage rating, the Amphenol ICC part is the appropriate choice. Contact the manufacturer for voltage rating information on the 3M connector if required for your application.
