DEMM9SH D-Sub 9 Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The DEMM9SH is a 9 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, featuring female sockets with panel mount, through hole solder termination. This connector is classified as an active product with full RoHS compliance and operates across an industrial temperature range of -55°C to 150°C. The part is designed for signal applications requiring reliable D-Sub connectivity in panel-mounted configurations.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the original part becomes unavailable or when alternative packaging or termination methods are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMM9SH is determined by the following critical parameters:

• Connector Style & Type: All substitutes must be D-Sub receptacles with female sockets
• Position Count & Layout: 9 positions in 2-row configuration, shell size 1 (DE, E)
• Contact Type: Signal contact application
• Flammability Rating: UL94 V-0 compliance required
• RoHS Compliance: All substitutes must meet RoHS requirements
• Termination Method: Solder or press-fit termination acceptable for through-hole mounting

The identified substitute parts meet these core criteria while differing in shell material finish, contact material composition, and operating temperature ranges. Termination method variations (solder versus press-fit) are acceptable substitutions for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Solder Termination Substitutes:

7-1393740-0 (TE Connectivity AMPLIMITE HD-20) provides the closest functional match with solder termination identical to the DEMM9SH. This part carries ROHS3 compliance and includes a ground strap feature. Operating temperature specification is not provided for this part.

D09S24A6RV22LF (Amphenol ICC Delta D) offers solder paste termination suitable for automated assembly processes. This part specifies 5A per contact current rating and 300V voltage rating. Operating temperature is limited to -55°C minimum specification.

Press-Fit Termination Alternatives:

5747091-2 and 5786143-1 (both TE Connectivity AMPLIMITE HD-20 series) provide press-fit termination as an alternative to solder attachment. Both parts are RoHS compliant with operating temperature range of -55°C to 105°C. The 5786143-1 variant is packaged in trays and carries REACH Affected status, while 5747091-2 is supplied in bulk packaging.

Temperature Consideration:

The DEMM9SH operates to 150°C. Substitute parts 5747091-2 and 5786143-1 are rated only to 105°C, and D09S24A6RV22LF specifies -55°C minimum. Applications requiring the full 150°C upper temperature range of the original part should confirm substitute part thermal performance with the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can press-fit termination parts substitute for solder termination?

A: Yes. Press-fit and solder termination methods are functionally equivalent for through-hole mounting applications. Selection depends on assembly process capability and PCB design. Press-fit termination (5747091-2, 5786143-1) eliminates solder reflow requirements, while solder termination (DEMM9SH, 7-1393740-0) and solder paste termination (D09S24A6RV22LF) require thermal processing.

Q: What is the difference between the TE Connectivity press-fit options?

A: Parts 5747091-2 and 5786143-1 are electrically and mechanically identical AMPLIMITE HD-20 series connectors. The primary difference is packaging: 5747091-2 is supplied in bulk, while 5786143-1 is supplied in trays. The 5786143-1 carries REACH Affected regulatory status, whereas 5747091-2 status is vendor undefined.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts meet RoHS requirements. The DEMM9SH and most substitutes carry RoHS Compliant status. Part 7-1393740-0 carries ROHS3 Compliant status, which represents an updated RoHS directive compliance level.

Q: What are the current rating differences?

A: The DEMM9SH is rated at 7.5A. The D09S24A6RV22LF specifies 5A per contact. Parts 5747091-2, 5786143-1, and 7-1393740-0 do not provide current rating specifications in available documentation.

Q: Does shell material finish affect substitution?

A: Shell material finish differences (yellow chromate plated zinc on DEMM9SH versus tin or nickel plating on substitutes) do not prevent functional substitution. Material finish selection depends on environmental corrosion requirements and application-specific specifications. All parts maintain gold contact finish for signal integrity.

Q: Can I use D09S24A6RV22LF in high-temperature applications?

A: The D09S24A6RV22LF specifies -55°C as the operating temperature limit. This part is not suitable for applications requiring sustained operation above -55°C. For applications requiring the DEMM9SH's full -55°C to 150°C range, 7-1393740-0 or direct DEMM9SH sourcing is recommended, pending confirmation of 7-1393740-0 temperature specifications with the manufacturer.
