DEMM9SF D-Sub 9 Position Receptacle Connector

Part Overview

The DEMM9SF is a 9 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through hole, right angle solder termination applications. This connector features female sockets in a 2-row configuration with shell size 1 (DE, E) layout. The part is currently active in production with 866 units in stock.

Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging options are required, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMM9SF is determined by the following critical parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Mounting type (Panel Mount, Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish (Gold)
• Material flammability rating (UL94 V-0)

The substitute parts identified—1-106505-2, 5-106505-2, and 8-1393480-1—all share these core mechanical and electrical characteristics. Variations in shell material finish, contact material composition, current rating, operating temperature range, and RoHS compliance status do not prevent functional substitution when the application requirements permit such variations.

Parameter Comparison

Engineering Selection Recommendations

1-106505-2 and 5-106505-2 (TE Connectivity AMPLIMITE HD-20 Series)

These parts are functionally equivalent to the DEMM9SF for applications where the operating temperature range of -55°C to 105°C is acceptable and current requirements do not exceed 6A. Both parts are ROHS3 compliant, offering regulatory advantage over the non-compliant DEMM9SF. The primary difference between these two substitutes is packaging: 1-106505-2 is supplied in trays, while 5-106505-2 is supplied in bulk. The 1-106505-2 includes a board lock feature and specifies 4-40 flange fastening, whereas 5-106505-2 features an unthreaded housing/shell. Both maintain gold contact finish and UL94 V-0 flammability rating.

8-1393480-1 (TE Connectivity AMPLIMITE HD-20 Series)

This part shares the same D-Sub 9-position receptacle configuration and is suitable for applications where current requirements are limited to 2.2A and operating temperatures do not exceed 125°C. The 8-1393480-1 is RoHS compliant and features a board lock with 4-40 flange fastening. The connector is supplied in bulk packaging and is distinguished by its gray color and reduced current rating compared to other substitutes.

All three substitute parts maintain the critical mechanical compatibility (shell size 1 / DE, E layout, 9-position, 2-row configuration, right angle solder termination) required for direct substitution in panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the DEMM9SF be directly replaced with 1-106505-2 or 5-106505-2?

A: Yes, both parts are mechanically and electrically compatible for applications where the operating temperature range of -55°C to 105°C and current rating of 6A meet design requirements. The primary differences are packaging format (tray vs. bulk), flange configuration (4-40 threaded vs. unthreaded), and RoHS compliance status.

Q: What is the key difference between 1-106505-2 and 5-106505-2?

A: Both parts are identical in electrical and mechanical specifications. The difference is packaging: 1-106505-2 is supplied in trays with a board lock feature and 4-40 threaded flange, while 5-106505-2 is supplied in bulk with an unthreaded housing/shell. Select based on your procurement and assembly requirements.

Q: Is 8-1393480-1 suitable as a substitute for high-current applications?

A: No. The 8-1393480-1 has a current rating of 2.2A, significantly lower than the DEMM9SF (7.5A) and the other substitutes (6A). This part is suitable only for low-current signal applications. For applications requiring 6A or higher current capacity, use 1-106505-2 or 5-106505-2.

Q: What are the temperature operating range differences among these parts?

A: The DEMM9SF operates from -55°C to 150°C. The 1-106505-2 and 5-106505-2 operate from -55°C to 105°C. The 8-1393480-1 operates from -55°C to 125°C. Select the substitute based on your application's maximum operating temperature requirement.

Q: Are all substitute parts RoHS compliant?

A: The DEMM9SF is RoHS non-compliant. All three substitutes (1-106505-2, 5-106505-2, and 8-1393480-1) are RoHS compliant, offering regulatory advantage for applications subject to RoHS requirements.

Q: Do the substitute parts maintain the same contact finish specifications?

A: All parts feature gold contact finish. The DEMM9SF specifies 50.0µin (1.27µm) thickness, while 1-106505-2 and 5-106505-2 specify 30.0µin (0.76µm). The 8-1393480-1 does not specify contact finish thickness. For applications with strict contact finish requirements, verify compatibility with your design specifications.
