Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the L17DCFRBA37PC309 is determined by the following core parameters that must remain consistent across all alternatives:

Critical 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
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0

Variable Parameters Allowing Substitution:

• Mounting Type (Free Hanging vs. Panel Mount)
• Flange Feature (Cable Side vs. Housing/Shell variations)
• Shell Material Finish (Nickel Plated vs. Tin Plated)
• Contact Finish (Gold vs. alternative finishes)
• Current Rating (5A vs. lower ratings)
• Voltage Rating (250V vs. unspecified)
• Operating Temperature Range
• Manufacturer (Amphenol ICC vs. 3M vs. HARTING)
• Packaging (Tray vs. Bulk)

The substitute parts 8237-6000, 8237-6003, 8237-6009, 8237-7000, and 09664286700 all maintain the critical matching parameters while differing in mounting configuration (panel mount instead of free hanging), flange design, and current rating specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: L17DCFRBA37PC309 (Amphenol ICC)

The L17DCFRBA37PC309 remains the preferred choice for applications requiring free-hanging, in-line mounting with cable-side flange attachment. This connector offers the highest current rating (5A) and specified voltage rating (250V) among all alternatives. The part is in active product status with robust inventory availability (702 units). RoHS compliance is confirmed, and MSL rating of 1 provides unlimited shelf life.

Secondary Selection: 8237-6009 (3M)

The 8237-6009 is suitable for panel-mount applications where the housing/shell flange is required instead of cable-side attachment. This part maintains UL94 V-0 flammability rating and gold contact finish with 30.0µin thickness. The part is in active status with 886 units available. ROHS3 compliance is confirmed. The reduced current rating (1A) requires circuit design verification if the original application demands 5A capacity.

Secondary Selection: 8237-6003 (3M)

The 8237-6003 provides panel-mount capability with a 4-40 threaded flange feature for secure panel attachment. This variant maintains gold contact finish and UL94 V-0 rating. The part is active with 739 units in stock. ROHS3 compliance and REACH Affected status are documented. Current rating of 1A requires application review.

Tertiary Selection: 09664286700 (HARTING)

The 09664286700 offers panel-mount configuration with unthreaded housing/shell flange. This part is in active status with 1034 units available. ROHS3 compliance and REACH Unaffected status are confirmed. The current rating of 2A is intermediate between the primary part (5A) and 3M alternatives (1A). Contact finish specifications are not provided.

Not Recommended: 8237-7000 (3M)

The 8237-7000 is in obsolete product status and should not be selected for new designs or long-term applications. Although inventory is available (1313 units), obsolescence status indicates discontinued manufacturer support and potential supply discontinuation.

Frequently Asked Questions (FAQ)

Q: Can the L17DCFRBA37PC309 be directly replaced with a panel-mount substitute?

A: Direct replacement depends on the mechanical mounting requirements of the application. The L17DCFRBA37PC309 is designed for free-hanging, in-line installation with M3 cable-side flange attachment. Panel-mount alternatives (8237-6000, 8237-6003, 8237-6009, 09664286700) require different mounting hardware and panel cutout specifications. Mechanical redesign of the mounting interface is necessary for substitution.

Q: What is the impact of reduced current rating when substituting with 3M parts?

A: The L17DCFRBA37PC309 is rated for 5A continuous current, while 3M alternatives (8237-6000, 8237-6003, 8237-6009) are rated for 1A. The 09664286700 (HARTING) is rated for 2A. Substitution is only acceptable if the circuit design operates at or below the substitute part's current rating. Applications requiring 5A capacity cannot use 1A-rated alternatives without circuit modification or parallel connector implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The L17DCFRBA37PC309 is RoHS Compliant. All substitute parts carry either RoHS Compliant or ROHS3 Compliant status. ROHS3 represents the updated RoHS Directive 2011/65/EU compliance standard. Both certifications are acceptable for regulatory purposes.

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

A: The 8237-6000 features an unthreaded housing/shell flange, suitable for applications where the connector is secured through friction fit or adhesive methods. The 8237-6003 features a 4-40 threaded flange, allowing mechanical fastening with M3 or equivalent screws for secure panel mounting. Selection depends on the panel attachment method required by the application.

Q: Can the L17DCFRBA37PC309 be substituted with the HARTING 09664286700?

A: Substitution is possible only if the application can accommodate panel-mount configuration and the 2A current rating. The 09664286700 maintains the same 37-position, 2-row D-Sub configuration with IDC ribbon cable termination and UL94 V-0 rating. However, the mounting type change from free-hanging to panel mount requires mechanical redesign. Contact finish specifications for the HARTING part are not provided, which may affect signal integrity in high-frequency applications.

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

A: The 8237-7000 is included in the substitute parts list for historical reference and inventory tracking purposes. The part is in obsolete product status, indicating that 3M has discontinued active manufacturing and support. Although 1313 units are currently in stock, new designs should not incorporate this part. Existing applications using 8237-7000 should transition to active alternatives such as 8237-6009 or 8237-6000.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The L17DCFRBA37PC309 operates from -25°C to 85°C. The 3M alternatives (8237-6000, 8237-6003, 8237-6009, 8237-7000) operate from -55°C to 105°C, providing a wider temperature range. The HARTING 09664286700 does not specify operating temperature. Applications requiring operation below -25°C or above 85°C should use 3M alternatives. Applications with temperature requirements within -25°C to 85°C can use any substitute without thermal limitation.

Q: Is packaging format (Tray vs. Bulk) a factor in substitution?

A: Packaging format does not affect electrical or mechanical compatibility. The L17DCFRBA37PC309 is supplied in Tray packaging, while 8237-6009 and 8237-7000 are supplied in Bulk packaging. The 8237-6000 and 8237-6003 are supplied in Tray packaging. Selection between Tray and Bulk depends on inventory management, handling procedures, and storage requirements rather than functional substitution criteria.
