L17DCFRBA37S D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The L17DCFRBA37S is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC, designed for IDC ribbon cable termination in free-hanging inline applications. This connector features female sockets with tin-plated steel shell and gold-plated contacts, rated for 3A at 250V across an operating temperature range of -55°C to 105°C. The product maintains active status with full RoHS compliance and MSL Level 1 rating.

Substitute parts are identified when equivalent D-Sub receptacle connectors share critical electrical and mechanical parameters while differing in specific design aspects such as mounting configuration, current rating, or contact material composition. Alternative components may be necessary due to inventory availability, application-specific mounting requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L17DCFRBA37S is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Termination Type: IDC, Ribbon Cable
• Operating Temperature Range: -55°C to 105°C
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Mounting Type (Free Hanging vs. Panel Mount)
• Current Rating (3A vs. 1A)
• Contact Material (Brass vs. Copper Alloy)
• Contact Finish Thickness (Flash vs. 30.0µin)
• Dielectric Material composition (Thermoplastic Glass Filled vs. PBT/Polyester Glass Filled)
• Wire Gauge tolerance (26 AWG vs. 26-28 AWG)
• Shell Color (Black vs. Gray)
• Packaging format (Tray vs. Bulk)

The substitute part 8337-6009 (3M) qualifies as an equivalent component based on matching all mandatory parameters while differing in mounting configuration and current rating specifications.

Engineering Selection Recommendations

L17DCFRBA37S Selection Criteria:

• Applications requiring free-hanging inline mounting configuration
• Systems demanding 3A current capacity per contact
• Designs specifying 250V voltage rating
• Implementations utilizing 26 AWG ribbon cable exclusively
• Assemblies requiring brass contact material specifications

8337-6009 Selection Criteria:

• Applications requiring panel-mount connector configuration
• Systems with maximum 1A current requirement per contact
• Designs accommodating 26-28 AWG ribbon cable flexibility
• Implementations utilizing copper alloy contact material
• Assemblies where gray connector color is specified

Both components maintain active product status with full compliance to RoHS and UL94 V-0 flammability standards. The 8337-6009 provides ROHS3 compliance certification. Both connectors support MSL Level 1 rating with unlimited moisture sensitivity tolerance. Selection between these components depends on specific mounting requirements and current load specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 8337-6009 directly replace the L17DCFRBA37S in existing designs?

A: Direct replacement is not recommended without design review. While both connectors share identical 37-position D-Sub receptacle configuration with IDC ribbon cable termination, the 8337-6009 features panel-mount design versus the L17DCFRBA37S free-hanging inline mounting. Additionally, the 8337-6009 current rating of 1A is lower than the L17DCFRBA37S 3A specification. Applications operating above 1A require the L17DCFRBA37S.

Q: What are the key electrical differences between these connectors?

A: The L17DCFRBA37S provides 3A current rating at 250V, while the 8337-6009 supports 1A with unspecified voltage rating. Both operate across -55°C to 105°C temperature range. Contact finish thickness differs: L17DCFRBA37S uses flash gold plating; 8337-6009 specifies 30.0µin (0.76µm) gold plating.

Q: Are there compatibility concerns with ribbon cable gauge?

A: The L17DCFRBA37S specifies 26 AWG ribbon cable. The 8337-6009 accommodates 26-28 AWG range. When substituting, confirm that existing ribbon cable gauge falls within the substitute connector's specified range.

Q: Do both connectors meet the same compliance standards?

A: Both connectors achieve UL94 V-0 flammability rating and MSL Level 1 moisture sensitivity classification. The L17DCFRBA37S carries RoHS Compliant status; the 8337-6009 carries ROHS3 Compliant status. Both are active products suitable for current production applications.

Q: What mounting considerations apply when selecting between these parts?

A: The L17DCFRBA37S features free-hanging inline mounting with cable-side M3 flange. The 8337-6009 features panel-mount configuration with unthreaded housing flange. Application mechanical design must accommodate the selected mounting style.

Q: How do contact materials differ between these connectors?

A: The L17DCFRBA37S uses brass contacts with flash gold plating. The 8337-6009 uses copper alloy contacts with 30.0µin gold plating. Both materials provide suitable conductivity for signal-level applications within their respective current ratings.
