Part Overview

The L17DCFRDA37P is a 37 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins, IDC ribbon cable termination, and free hanging in-line mounting. The part is currently active in production with 880 units in stock.

Substitute parts are identified when equivalent D-Sub 37 position plug connectors share the same connector style, position count, pin configuration, and termination method. Alternatives may differ in mounting type, current rating, or manufacturer while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L17DCFRDA37P are identified based on the following critical parameters that must remain constant:

Mandatory 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)
• Termination: IDC, Ribbon Cable
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parameters Allowed to Vary:

• Manufacturer
• Mounting Type (Free Hanging vs. Panel Mount)
• Current Rating (Amps)
• Voltage Rating
• Contact Finish specifications
• Packaging format (Tray vs. Bulk)
• Product Status (Active vs. Obsolete)

The identified substitute parts maintain the core D-Sub 37 position plug connector architecture with IDC ribbon cable termination. Variations in mounting type and current rating reflect different application requirements while preserving mechanical and electrical compatibility within the D-Sub connector family.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

The L17DCFRDA37P remains the preferred choice for new designs due to its active product status and higher current rating of 3A. This part is manufactured by Amphenol ICC and provides the specified 250V voltage rating with free hanging in-line mounting configuration.

Active Substitute Options:

The 3M 8237 series connectors (8237-6000, 8237-6003, 8237-6009) are active alternatives suitable for applications where panel mount configuration is required. These parts maintain the 37 position D-Sub plug architecture with IDC ribbon cable termination and operate across the same temperature range (-55°C ~ 105°C). Current rating for 3M parts is 1A, which is lower than the main part and must be evaluated against application requirements.

The HARTING 09664286700 is an active alternative with 2A current rating and panel mount configuration. This part provides a mid-range current capacity between the main part and the 3M series.

Obsolete Status Consideration:

The 3M 8237-7000 is marked as obsolete and should not be selected for new designs or long-term production applications. This part is listed for reference only in legacy system documentation.

Compliance Status:

All active substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. RoHS compliance is confirmed across all active alternatives. The HARTING part carries ROHS3 Compliant status with REACH Unaffected designation. The 3M 8237-6003 is REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can the L17DCFRDA37P be replaced with a panel mount D-Sub 37 position connector?

A: Yes, panel mount alternatives such as 3M 8237-6000, 8237-6003, 8237-6009, or HARTING 09664286700 are mechanically and electrically compatible. The primary difference is mounting configuration. Panel mount connectors are secured to an enclosure or backplane, whereas the L17DCFRDA37P uses free hanging in-line mounting for cable-to-cable or cable-to-board connections. Application requirements determine which mounting type is appropriate.

Q: What is the significance of the current rating difference between the L17DCFRDA37P (3A) and substitute parts (1A to 2A)?

A: Current rating indicates the maximum continuous current each contact can safely carry. The L17DCFRDA37P supports 3A per contact, while most 3M alternatives support 1A per contact. The HARTING 09664286700 supports 2A per contact. Selection must be based on actual circuit current requirements. Lower-rated parts cannot be used in applications exceeding their current specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. The L17DCFRDA37P is RoHS Compliant. All identified active substitute parts (09664286700, 8237-6000, 8237-6003, 8237-6009) are ROHS3 Compliant or RoHS Compliant. The obsolete part 8237-7000 is RoHS Compliant but should not be used in new designs.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level (MSL) 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts carry MSL 1 rating, meaning they can be stored under standard warehouse conditions without desiccant packaging or controlled humidity requirements.

Q: Can the L17DCFRDA37P be used in applications requiring 250V?

A: Yes. The L17DCFRDA37P is rated for 250V. Substitute parts from the 3M 8237 series and HARTING 09664286700 do not specify voltage rating in available documentation. If 250V rating is a design requirement, the L17DCFRDA37P is the confirmed choice among the listed parts.

Q: What is the difference between Tray and Bulk packaging?

A: Packaging format affects order quantity and handling. Tray packaging (L17DCFRDA37P, 8237-6000, 8237-6003) typically accommodates smaller quantities per package. Bulk packaging (09664286700, 8237-6009, 8237-7000) is used for larger quantity orders. Packaging does not affect connector performance or compatibility.

Q: Why is the 3M 8237-7000 listed if it is obsolete?

A: The 8237-7000 is included for reference in legacy system documentation and reverse engineering applications. For new designs and ongoing production, active alternatives must be selected. Obsolete parts may have limited availability and no manufacturer support.

Q: Are all substitute parts suitable for the same operating temperature range?

A: The L17DCFRDA37P operates from -55°C to 105°C. The 3M 8237 series (8237-6000, 8237-6003, 8237-6009, 8237-7000) all operate across the same temperature range. The HARTING 09664286700 does not specify operating temperature in available documentation. If extended temperature operation is required, 3M alternatives or the main part are confirmed choices.
