DEMM9SDA197 D-Sub 9-Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The DEMM9SDA197 is a 9-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, featuring female sockets with right-angle solder termination and panel mount through-hole installation. This connector is classified as active product status and is designed for signal applications requiring robust mechanical and electrical performance in industrial and commercial environments.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers that meet equivalent electrical and mechanical specifications. The substitute parts listed maintain functional compatibility through matching connector geometry, pin configuration, termination method, and core electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMM9SDA197 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• 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
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Current rating: Substitute must meet or exceed 7.5A requirement
• Operating temperature range: Substitute must encompass or exceed -55°C ~ 150°C
• Contact material: Copper Alloy or Phosphor Bronze acceptable
• Shell material finish: Steel with tin or tin-nickel plating acceptable

The three substitute parts (1-106505-2, 5-106505-2, and 8-1393480-1) satisfy the primary matching criteria. Secondary parameter variations exist and are documented in the Parameter Comparison table below.

Engineering Selection Recommendations

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

These parts are functionally equivalent substitutes for applications where the operating temperature requirement does not exceed 105°C and current demand does not exceed 6A. Both parts maintain the same connector geometry, pin configuration, and solder termination compatibility. The primary distinction between these two parts is packaging format: 1-106505-2 is supplied in tray packaging, while 5-106505-2 is supplied in bulk packaging.

Both parts achieve ROHS3 compliance, providing regulatory advantage over the non-compliant DEMM9SDA197. The reduced contact finish thickness (30.0µin versus 50.0µin) remains within acceptable gold plating specifications for signal-level applications. The phosphor bronze contact material provides equivalent electrical performance to copper alloy contacts.

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

This part is a substitute only for applications with current requirements not exceeding 2.2A and operating temperatures within -55°C ~ 125°C. The significantly reduced current rating (2.2A versus 7.5A) restricts this part to low-current signal applications. The gray color and unspecified contact finish thickness represent additional deviations from the original specification. This part achieves RoHS compliance and is suitable only when current and temperature constraints are confirmed compatible with application requirements.

Compliance Considerations

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 classification. The TE Connectivity parts provide improved RoHS compliance status compared to the ITT Cannon original part. Selection should account for regulatory requirements in the target application environment.

Frequently Asked Questions (FAQ)

Q: Can 1-106505-2 or 5-106505-2 be used as direct replacements for DEMM9SDA197?

A: Yes, for applications where operating temperature does not exceed 105°C and current demand does not exceed 6A. Both parts maintain identical connector geometry, pin configuration, shell size (DE/E), and solder termination. The primary functional difference is the reduced current rating and operating temperature range. Verify application requirements before substitution.

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

A: These parts are electrically and mechanically identical. The only difference is packaging: 1-106505-2 is supplied in tray packaging, while 5-106505-2 is supplied in bulk packaging. Select based on procurement and inventory management requirements.

Q: Is 8-1393480-1 suitable as a substitute?

A: 8-1393480-1 is a substitute only for low-current applications (maximum 2.2A). The current rating is significantly lower than the original part (2.2A versus 7.5A). This part is not suitable for applications requiring the full 7.5A current capacity of the DEMM9SDA197. Confirm application current requirements before selection.

Q: What are the key differences in operating temperature ranges?

A: The DEMM9SDA197 operates from -55°C to 150°C. The TE Connectivity 1-106505-2 and 5-106505-2 operate from -55°C to 105°C, limiting their use in high-temperature applications. The 8-1393480-1 operates from -55°C to 125°C. Verify application temperature requirements to ensure substitute compatibility.

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The DEMM9SDA197 is RoHS non-compliant. All three substitute parts (1-106505-2, 5-106505-2, and 8-1393480-1) are RoHS compliant. If RoHS compliance is required for the application, all substitute parts meet this requirement.

Q: Does the contact finish thickness difference affect performance?

A: The DEMM9SDA197 has 50.0µin (1.27µm) gold plating, while 1-106505-2 and 5-106505-2 have 30.0µin (0.76µm). Both thicknesses are within acceptable specifications for signal-level D-Sub connectors. The thinner plating on substitute parts remains suitable for standard signal applications.

Q: Can I mix connector colors in my assembly?

A: The DEMM9SDA197 and 1-106505-2 and 5-106505-2 are black. The 8-1393480-1 is gray. Color consistency may be a design or assembly requirement. Verify color specifications for your application before selecting 8-1393480-1.
