DEM9SF D-Sub 9 Position Receptacle Connector

Part Overview

The DEM9SF is a 9 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through hole, right angle solder applications. This connector features female sockets with a DE/E shell size (1) and is rated for 7.5A continuous current operation across an operating temperature range of -55°C to 125°C. The part maintains active product status with 778 units currently in stock.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required, or when design requirements permit selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEM9SF is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting configuration: Panel Mount, Through Hole, Right Angle
• Termination method: Solder
• Material flammability rating: UL94 V-0
• Contact finish: Gold
• Operating temperature range: -55°C to 125°C minimum

The substitute parts listed below meet these core requirements. Variations in current rating, shell finish material, dielectric material composition, and contact material are noted in the parameter comparison table and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

1-106505-2 (TE Connectivity AMPLIMITE HD-20 Series, Tray Packaging)

This substitute is suitable for applications where the operating temperature maximum of 105°C is acceptable and current requirements do not exceed 6A. The part is ROHS3 compliant and includes board lock features. The 4-40 threaded flange provides mechanical retention advantages in certain mounting configurations. Tin plating on the steel shell offers corrosion resistance characteristics different from the yellow chromate finish of the primary part.

5-106505-2 (TE Connectivity AMPLIMITE HD-20 Series, Bulk Packaging)

This substitute shares electrical and mechanical specifications with 1-106505-2 but is supplied in bulk packaging format. It is ROHS3 compliant and features an unthreaded housing/shell flange, matching the primary part's flange configuration. Selection of this variant is appropriate when bulk packaging meets procurement requirements and operating temperature is limited to 105°C maximum.

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

This substitute maintains the full -55°C to 125°C operating temperature range of the primary part and is RoHS compliant. However, the current rating of 2.2A is significantly lower than the DEM9SF's 7.5A rating and is not suitable for applications requiring higher current capacity. The backset spacing of 0.371" (9.43mm) differs from the 0.406" (10.30mm) spacing of the other TE Connectivity alternatives. This part includes board lock features and a 4-40 threaded flange. Gray color distinguishes this variant from the black housing of the primary part.

Frequently Asked Questions (FAQ)

Q: Can I use 1-106505-2 or 5-106505-2 as a direct replacement for DEM9SF in all applications?

A: These parts are mechanically and electrically compatible for applications where the maximum operating temperature does not exceed 105°C and current requirements do not exceed 6A. If your application requires operation above 105°C or draws more than 6A, these substitutes are not appropriate. Both parts are ROHS3 compliant, whereas the DEM9SF is RoHS non-compliant.

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

A: Both parts are identical in electrical and mechanical specifications. The primary difference is packaging format: 1-106505-2 is supplied in trays, while 5-106505-2 is supplied in bulk. Selection depends on procurement and inventory management requirements.

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

A: No. The 8-1393480-1 is rated for only 2.2A continuous current, making it unsuitable for applications requiring the 7.5A capacity of the DEM9SF. This part should be selected only for low-current signal applications where its full temperature range capability (-55°C to 125°C) is required.

Q: What are the key differences in shell finish between these parts?

A: The DEM9SF features yellow chromate plated zinc finish. All TE Connectivity substitutes (1-106505-2, 5-106505-2, and 8-1393480-1) feature tin plated steel finish. These finishes provide different corrosion resistance profiles and may affect performance in specific environmental conditions.

Q: Do all these connectors have the same flange configuration?

A: No. The DEM9SF and 5-106505-2 feature unthreaded housing/shell flanges. The 1-106505-2 and 8-1393480-1 feature 4-40 threaded flanges, which provide mechanical retention through threaded fasteners. Mounting configuration must be verified against your application's panel design.

Q: Are there compliance differences I should consider?

A: Yes. The DEM9SF is RoHS non-compliant. The 1-106505-2 and 5-106505-2 are ROHS3 compliant. The 8-1393480-1 is RoHS compliant. If your application or regulatory environment requires RoHS compliance, the TE Connectivity alternatives are appropriate selections.
