DEM9SR D-Sub 9 Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The DEM9SR 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 1020 units in current inventory.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity. Substitutes must maintain functional compatibility across core electrical and mechanical parameters including connector style, position count, mounting configuration, shell size, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DEM9SR are qualified based on strict equivalence across the following mandatory parameters:

• Connector style: D-Sub receptacle configuration
• Position count and row arrangement: 9 positions, 2 rows
• Shell size and layout: Size 1 (DE, E)
• Mounting configuration: Panel mount, through hole, right angle orientation
• Termination method: Solder
• Contact type: Signal contacts
• Material flammability: UL94 V-0 rating

The three identified substitutes (1-106505-2, 5-106505-2, and 8-1393480-1) all satisfy these core functional requirements. Variations exist in secondary parameters including current rating, operating temperature range, shell finish material, contact material composition, and regulatory compliance status. These variations do not preclude substitution but must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and satisfy core functional requirements for D-Sub 9 position receptacle applications. Selection between the DEM9SR and its substitutes depends on specific application constraints:

1-106505-2 and 5-106505-2 (TE Connectivity AMPLIMITE HD-20 Series): These parts are functionally equivalent with the primary distinction being packaging format (Tray versus Bulk). Both feature ROHS3 compliance, reduced current rating (6A versus 7.5A), and lower maximum operating temperature (105°C versus 125°C). The 1-106505-2 includes board lock features and 4-40 flange configuration. These parts are suitable for applications where RoHS3 compliance is required and current demands do not exceed 6A.

8-1393480-1 (TE Connectivity AMPLIMITE HD-20 Series): This part maintains the full -55°C to 125°C operating temperature range of the DEM9SR but features significantly reduced current rating (2.2A). It includes board lock features and 4-40 flange configuration. RoHS compliance is confirmed. This part is suitable for low-current signal applications requiring extended temperature operation.

Applications requiring the full 7.5A current rating of the DEM9SR should retain the original part or evaluate alternative substitutes not listed here. Applications operating above 105°C should confirm compatibility with the DEM9SR's extended temperature range or select the 8-1393480-1 alternative.

Frequently Asked Questions (FAQ)

Q: Can 1-106505-2 or 5-106505-2 be used as direct replacements for DEM9SR in high-current applications?

A: Both TE Connectivity parts are rated for 6A maximum continuous current, compared to the DEM9SR's 7.5A rating. Applications requiring current levels between 6A and 7.5A cannot use these substitutes. Verify actual application current requirements before substitution.

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

A: Both parts are electrically and mechanically identical AMPLIMITE HD-20 series connectors. The primary difference is packaging: 1-106505-2 is supplied in Tray packaging, while 5-106505-2 is supplied in Bulk packaging. Electrical specifications, flange configuration (4-40), and board lock features are identical.

Q: Is 8-1393480-1 suitable for applications currently using DEM9SR?

A: The 8-1393480-1 maintains the full -55°C to 125°C operating temperature range and RoHS compliance of the DEM9SR. However, its 2.2A current rating is significantly lower. This part is suitable only for low-current signal applications. High-current applications cannot use this substitute.

Q: What are the compliance differences between DEM9SR and the TE Connectivity substitutes?

A: The DEM9SR is RoHS non-compliant. Both 1-106505-2 and 5-106505-2 are ROHS3 compliant. The 8-1393480-1 is RoHS compliant. Applications subject to RoHS requirements must use one of the TE Connectivity alternatives.

Q: Does the shell finish difference (Yellow Chromate Plated Zinc versus Tin Plated) affect substitution?

A: Both finishes provide corrosion protection suitable for D-Sub connectors. The choice between finishes depends on environmental exposure and specific application requirements. No functional incompatibility exists between these finish types for standard D-Sub applications.

Q: Can the gray-colored 8-1393480-1 be used in applications specifying black connectors?

A: Color is a cosmetic parameter. The gray 8-1393480-1 is functionally equivalent to black alternatives. Substitution is acceptable unless application documentation explicitly requires black color for identification or assembly purposes.
