Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMM9PB is determined by the following critical parameters:

Core Compatibility Requirements:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 9
• Number of rows: 2
• Shell size, connector layout: 1 (DE, E)
• Termination: Solder

Performance Parameters:

• Current rating: Substitute must meet or exceed 7.5A
• Operating temperature range: Substitute must cover -55°C ~ 150°C or be suitable for the intended application temperature window
• Contact finish: Gold plating required
• Material flammability: UL94 V-0 compliance required

Compliance Parameters:

• RoHS compliance status
• ECCN and HTSUS classifications

Substitute parts are grouped into two categories: direct panel mount through-hole substitutes (172-009-112R911, L717SDEH09POL2RM8, M24308/24-7F) and alternative mounting configuration substitutes with different flange features or termination methods (627-009-220-046, 627-009-220-047, 627-009-220-048, 627-009-222-042).

Parameter Comparison

Engineering Selection Recommendations

Direct Panel Mount Substitutes (Preferred Category):

The 172-009-112R911 (NorComp Inc.) and L717SDEH09POL2RM8 (Amphenol ICC) maintain panel mount through-hole configuration matching the DEMM9PB. The 172-009-112R911 is obsolete product status and should be avoided for new designs. The L717SDEH09POL2RM8 is active status with RoHS compliance and operates to -55°C ~ 125°C, providing adequate thermal range for most applications below 125°C. Current rating of 3A per contact is lower than the DEMM9PB specification of 7.5A.

The M24308/24-7F (TE Connectivity Aerospace, Defense and Marine) maintains panel mount configuration and 5A current rating but carries RoHS non-compliant status and REACH affected designation. This part is suitable only for applications where RoHS compliance is not required.

Alternative Mounting Configuration Substitutes:

The 627-009-220-046, 627-009-220-047, and 627-009-220-048 (Mercury United Electronics, Inc.) feature board-side flange mounting rather than panel mount configuration. These parts are active status with ROHS3 compliance but operate only to -55°C ~ 85°C and provide 3A per contact current rating. These substitutes are applicable only when board-side mounting is acceptable and thermal requirements do not exceed 85°C.

The 627-009-222-042 (Mercury United Electronics, Inc.) features free-hanging in-line mounting with solder cup termination, representing a different mechanical configuration. This part is suitable only when in-line mounting is required.

Compliance Considerations:

For applications requiring RoHS compliance, select from: DEMM9PB (RoHS Compliant), 172-009-112R911 (ROHS3 Compliant, obsolete), 627-009-220-046/047/048 (ROHS3 Compliant), 627-009-222-042 (ROHS3 Compliant), or L717SDEH09POL2RM8 (RoHS Compliant). The M24308/24-7F is not suitable for RoHS-mandated applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower current rating than the DEMM9PB?

A: No. The DEMM9PB is rated for 7.5A. Substitute parts with lower current ratings (3A or 5A) must not be used in applications requiring the full 7.5A specification. Verify actual application current requirements before selecting a substitute with reduced current capacity.

Q: What is the difference between panel mount and board-side flange mounting?

A: Panel mount connectors (DEMM9PB, 172-009-112R911, M24308/24-7F) are installed through a panel opening with the connector body protruding from the panel. Board-side flange mounting (627-009-220-046/047/048) positions the connector on the circuit board surface with a flange for mechanical retention. These are not interchangeable mounting configurations.

Q: Are all substitute parts RoHS compliant?

A: No. The M24308/24-7F is RoHS non-compliant. All other listed substitutes are either RoHS Compliant or ROHS3 Compliant. Verify RoHS compliance requirements for your application before part selection.

Q: What is the significance of contact finish thickness?

A: The DEMM9PB and M24308/24-7F specify 50.0µin (1.27µm) gold plating thickness. Other substitutes specify flash gold plating, which is thinner. Flash plating provides adequate contact performance for signal applications but may have different wear characteristics in high-cycle mating applications.

Q: Can I substitute the DEMM9PB with a part rated for lower operating temperature?

A: No. The DEMM9PB operates from -55°C to 150°C. Substitutes with lower maximum temperature ratings (85°C or 100°C) must not be used in applications requiring operation above their specified maximum temperature. Verify the actual operating temperature range required for your application.

Q: What is the difference between solder and solder cup termination?

A: Solder termination (DEMM9PB and most substitutes) involves soldering individual wires to contact pins. Solder cup termination (627-009-222-042) features cup-shaped contact ends designed for wire insertion and solder filling. These termination methods are not interchangeable and require different assembly processes.

Q: Is the 172-009-112R911 suitable for new designs?

A: No. The 172-009-112R911 is classified as obsolete product status. For new designs, select from active status parts: 627-009-220-046/047/048, 627-009-222-042, L717SDEH09POL2RM8, or M24308/24-7F.

Q: What packaging options are available for substitutes?

A: The DEMM9PB is supplied in unspecified packaging. Substitutes are available in: Tray (172-009-112R911, L717SDEH09POL2RM8, 627-009-220-047), Tube (627-009-220-046), Bulk (627-009-222-042, M24308/24-7F), and 627-009-220-048 (Tray). Verify packaging requirements for procurement and handling procedures.
