L117DCFRA37P D-Sub Plug 37 Position IDC Connector

Part Overview

The L117DCFRA37P is a 37 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) with male pins and IDC ribbon cable termination. This free-hanging, in-line connector is designed for signal applications requiring a 250V rating and 3A current capacity across an operating temperature range of -55°C to 105°C. The connector features a tin-plated steel shell with gold-plated brass contacts and is UL94 V-0 rated with RoHS compliance.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative mounting configurations are required (such as panel mount versus free-hanging), or when design specifications allow for compatible alternatives from different manufacturers that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L117DCFRA37P is determined by strict alignment of the following core parameters:

Critical Parameters (Must Match):

• Connector type: D-Sub Plug with male pins
• Number of positions: 37
• Number of rows: 2
• Shell size / connector layout: 4 (DC, C)
• Termination method: IDC, Ribbon Cable
• Contact type: Signal
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Mounting type: Free-hanging (in-line) or panel mount configurations are functionally compatible when the application permits
• Shell material finish: Steel with tin or alternative finishes
• Contact material and finish: Brass or copper alloy with gold or alternative finishes
• Current rating: Substitute parts may have lower current ratings (1A to 3A) depending on application requirements
• Voltage rating: Substitute parts may have unspecified voltage ratings if the application does not exceed 250V
• Operating temperature: Substitute parts with -55°C to 105°C range are compatible
• Contact finish thickness: Variations in gold plating thickness (15.0µin to 30.0µin) are acceptable
• Dielectric material: Thermoplastic glass-filled or polybutylene terephthalate (PBT) polyester glass-filled materials are compatible
• Packaging: Tray or bulk packaging does not affect functional compatibility

Product Status Consideration: The L117DCFRA37P is active status. Substitute parts 8237-7000 is marked obsolete and should be avoided for new designs. Active status parts are preferred for ongoing production and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs):

The 8237-6009 (3M) is the preferred substitute when panel mount configuration is acceptable. This part maintains active product status, ROHS3 compliance, and all critical electrical and mechanical parameters. The 1A current rating is suitable for applications not requiring the full 3A capacity of the L117DCFRA37P. The 30.0µin gold contact finish provides enhanced durability compared to the 15.0µin specification of the main part.

Secondary Substitutes (Active Status):

The 8237-6000 and 8237-6003 (3M) are functionally equivalent alternatives with identical electrical specifications to 8237-6009. The 8237-6003 includes a 4-40 threaded flange feature, providing additional mechanical mounting options. Both maintain active status and ROHS3 compliance.

The 09664286700 (HARTING) is an active status alternative with panel mount configuration. The 2A current rating exceeds the minimum requirements for most applications. Steel shell finish without specified plating is acceptable for applications not requiring tin plating.

Not Recommended for New Designs:

The 8237-7000 (3M) is marked obsolete and should not be selected for new production designs. While electrically and mechanically compatible, obsolete status indicates discontinued manufacturing and limited future availability.

Mounting Configuration Consideration:

The L117DCFRA37P is configured for free-hanging (in-line) mounting. All substitute parts listed are panel mount configurations. Selection of a panel mount substitute requires confirmation that the application design accommodates panel mounting. If free-hanging mounting is mandatory, the L117DCFRA37P remains the only option among the listed parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute a panel mount D-Sub connector for the free-hanging L117DCFRA37P?

A: Panel mount and free-hanging connectors have different mechanical mounting interfaces. Substitution is only possible if the application design can accommodate panel mounting. The electrical and signal characteristics are identical, but the physical installation method differs. Confirm mounting requirements before selecting a panel mount alternative.

Q: What is the significance of the current rating difference between L117DCFRA37P (3A) and the 3M substitutes (1A)?

A: The L117DCFRA37P supports 3A per contact, while 3M alternatives support 1A per contact. Selection depends on actual circuit current requirements. If the application draws less than 1A per contact, the lower-rated substitutes are acceptable. If the application requires 1A to 3A per contact, the L117DCFRA37P or 09664286700 (2A) must be used.

Q: Are the contact finish differences between 15.0µin and 30.0µin significant?

A: Both thicknesses meet UL94 V-0 and RoHS requirements. The 30.0µin gold plating on 3M substitutes provides greater contact durability and corrosion resistance compared to the 15.0µin specification. For applications with frequent mating cycles or harsh environments, the thicker plating is beneficial.

Q: Why is 8237-7000 marked obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While existing inventory may be available, long-term supply cannot be guaranteed. For new designs and ongoing production, active status parts (8237-6009, 8237-6000, 8237-6003, or 09664286700) are recommended.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: ROHS3 refers to compliance with the Restriction of Hazardous Substances Directive 2011/65/EU (recast), which is the current regulatory standard. RoHS Compliant typically refers to the original 2002/95/EC directive. ROHS3 compliance is the current requirement and is preferred for new designs. Both designations indicate restriction of hazardous substances.

Q: Can I use 09664286700 (HARTING) as a direct replacement for L117DCFRA37P?

A: The 09664286700 is electrically and mechanically compatible for signal applications. Key differences are panel mount configuration (versus free-hanging), 2A current rating (versus 3A), and unspecified voltage rating. If the application permits panel mounting and does not exceed 2A per contact, this part is a valid substitute.

Q: Are all listed substitutes compatible with 26 AWG ribbon cable?

A: The L117DCFRA37P specifies 26 AWG wire gauge. Substitute parts do not specify wire gauge in the provided data. IDC termination compatibility is confirmed for all listed parts. Verify ribbon cable gauge compatibility with the connector manufacturer if wire gauge is critical to the application.

Q: What is the difference between the 8237-6000 and 8237-6003?

A: Both are 3M 8200 series 37-position D-Sub plugs with identical electrical specifications. The primary difference is the flange feature: 8237-6000 has an unthreaded housing/shell, while 8237-6003 has a 4-40 threaded flange. The threaded flange on 8237-6003 provides screw-mount capability for panel installations.

Q: Is the L117DCFRA37P available in panel mount configuration?

A: No. The L117DCFRA37P is exclusively configured for free-hanging (in-line) mounting. If panel mount is required, alternative connectors from the substitute list must be evaluated, with confirmation that the application design supports panel mounting.
