DEMZ9SN D-Sub 9 Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The DEMZ9SN is a 9 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through hole solder applications. This connector features female sockets with a board side flange and board lock feature, operating across -55°C to 125°C. The part is currently active in production with 731 units in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative connector configurations that maintain functional compatibility within the same D-Sub category and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMZ9SN is determined by strict alignment with the following core parameters:

• Connector Style & Type: Must be D-Sub receptacle with female sockets
• Position & Row Configuration: Must maintain 9 positions in 2 rows
• Shell Size & Layout: Must be Size 1 (DE, E) to ensure mechanical compatibility with mating plugs
• Contact Type: Must be signal contacts
• Termination Method: Solder termination is the primary requirement; press-fit alternatives may be considered where mechanical mounting compatibility is maintained
• Flange Configuration: Board side or mating side flanges are acceptable provided through-hole mounting is supported
• Material Compliance: UL94 V-0 flammability rating required
• Operating Temperature Range: Minimum -55°C to 125°C or equivalent
• Contact Material & Finish: Gold-plated contacts with copper alloy base material

The substitute parts identified below meet these core substitution criteria while maintaining functional equivalence within D-Sub 9 position receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

7-1393740-0 (TE Connectivity AMPLIMITE HD-20) is the primary substitute for solder termination applications. This part maintains identical termination methodology, shell size, position configuration, and contact type. Both parts are UL94 V-0 rated and support unlimited moisture sensitivity handling. The 7-1393740-0 carries ROHS3 compliance, providing regulatory advantage in applications where RoHS compliance is required. The contact material differs (phosphor bronze vs. copper alloy), which does not affect functional substitution within signal contact applications.

5786143-1 (TE Connectivity AMPLIMITE HD-20) is suitable for applications where press-fit termination is acceptable as an alternative to solder attachment. This part shares identical position, row, shell size, and contact type specifications. Press-fit termination eliminates soldering requirements and may reduce assembly time. The operating temperature range is -55°C to 105°C, which is 20°C lower than the DEMZ9SN maximum. This part is RoHS Compliant and carries REACH Affected status.

Both substitute parts are from the TE Connectivity AMPLIMITE HD-20 series and maintain mechanical compatibility with standard D-Sub 9 position plugs (Size 1, DE/E layout). Selection between these substitutes depends on termination method requirements and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can 5786143-1 be used in place of DEMZ9SN in existing designs?

A: 5786143-1 is mechanically and electrically compatible as a D-Sub 9 position receptacle. However, it uses press-fit termination instead of solder. PCB layout and assembly process must accommodate press-fit contact insertion. The operating temperature maximum is 105°C versus 125°C for DEMZ9SN; verify this meets application requirements.

Q: What is the difference between board side and mating side flanges?

A: Board side flanges (DEMZ9SN) mount directly to the PCB surface. Mating side flanges (5786143-1, 7-1393740-0) position the flange at the connector mating interface. Both configurations support through-hole mounting; flange position affects panel cutout and mechanical assembly approach.

Q: Are the substitute parts compatible with existing D-Sub 9 position plugs?

A: Yes. All three parts maintain Size 1 (DE, E) shell layout, which is the standard D-Sub 9 position configuration. Mating with standard D-Sub 9 position plugs is assured across all listed parts.

Q: Why does 7-1393740-0 show no operating temperature specification?

A: Operating temperature data was not provided in the component specification. Verify with TE Connectivity technical documentation or contact the manufacturer for complete thermal operating range before selection in temperature-critical applications.

Q: What is the significance of RoHS compliance differences?

A: DEMZ9SN is RoHS non-compliant. Both substitute parts (5786143-1 and 7-1393740-0) are RoHS compliant or ROHS3 compliant. If the application or end market requires RoHS compliance, substitutes provide regulatory alignment. Existing designs using DEMZ9SN may not require RoHS compliance; verify regulatory requirements before substitution.

Q: Can these parts be used interchangeably in the same assembly?

A: Mechanical and electrical interchangeability is confirmed for all three parts within D-Sub 9 position receptacle applications. However, termination method differences (solder vs. press-fit) require process-specific validation. Assembly procedures, PCB design, and quality control methods must be adapted to the selected termination technology.
