• Number of Positions: 9 (required match)
• Number of Rows: 2 (required match)
• Shell Size, Connector Layout: 1 (DE, E) (required match)
• Mounting Type: Panel Mount, Through Hole, Right Angle (required match)
• Termination: Solder (required match)
• Shell Material, Finish: Steel, Tin Plated (required match)
• Contact Finish: Gold (required match)
• Material Flammability Rating: UL94 V-0 (required match)

Secondary Compatibility Parameters (allowable variation):

• Current Rating: Substitute must meet or exceed 7.5A requirement
• Operating Temperature: Substitute must support minimum -55°C to 150°C range
• Contact Material: Copper Alloy or Phosphor Bronze acceptable
• Dielectric Material: PCT or Polyester/Glass Filled acceptable

The three identified substitute parts (1-106505-2, 5-106505-2, 8-1393480-1) satisfy all primary compatibility criteria and maintain functional equivalence within the D-Sub 9-position receptacle category.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: DEMM-9S-D

The DEMM-9S-D remains the primary specification when the full operating temperature range of -55°C to 150°C is required. This part is Active and maintains the highest current rating of 7.5A among all options. Selection of the DEMM-9S-D is appropriate for applications requiring extended thermal performance and maximum current capacity.

Secondary Selection: 1-106505-2 (TE Connectivity AMPLIMITE HD-20)

The 1-106505-2 is suitable as a substitute when operating temperature requirements do not exceed 105°C and current requirements do not exceed 6A. This part offers ROHS3 compliance, addressing regulatory requirements not met by the DEMM-9S-D. The 1-106505-2 is packaged in Tray format and includes Board Lock features. Inventory availability is 1990 pieces. This substitute is appropriate for new designs targeting RoHS3 compliance or when supply of the DEMM-9S-D is constrained.

Tertiary Selection: 5-106505-2 (TE Connectivity AMPLIMITE HD-20)

The 5-106505-2 is functionally equivalent to the 1-106505-2 with identical electrical and mechanical specifications. The primary distinction is packaging format (Bulk versus Tray) and REACH status documentation. This part is appropriate when bulk packaging is preferred and operating temperature does not exceed 105°C. Inventory availability is 999 pieces.

Quaternary Selection: 8-1393480-1 (TE Connectivity AMPLIMITE HD-20)

The 8-1393480-1 is a substitute option with significant parameter deviations. The current rating of 2.2A is substantially lower than the DEMM-9S-D (7.5A), and the operating temperature maximum of 125°C does not meet the full -55°C to 150°C requirement. The connector color is Gray rather than Black. This part is suitable only for applications with reduced current requirements (≤2.2A) and operating temperatures not exceeding 125°C. Selection of this part requires explicit verification that application requirements align with these reduced specifications.

Compliance Considerations:

All substitute parts (1-106505-2, 5-106505-2, 8-1393480-1) are RoHS Compliant or ROHS3 Compliant, whereas the DEMM-9S-D is RoHS non-compliant. Applications subject to RoHS regulations must select from the substitute parts. All parts maintain UL94 V-0 flammability rating and are classified as Active products.

Frequently Asked Questions (FAQ)

Q: Can the 1-106505-2 or 5-106505-2 be used as a direct replacement for the DEMM-9S-D in all applications?

A: The 1-106505-2 and 5-106505-2 are functionally equivalent substitutes for applications where the operating temperature does not exceed 105°C and current requirements do not exceed 6A. If your application requires operation at temperatures above 105°C or currents above 6A, these substitutes are not appropriate. The DEMM-9S-D supports -55°C to 150°C and 7.5A; the TE Connectivity parts support -55°C to 105°C and 6A.

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

A: Both parts are from the TE Connectivity AMPLIMITE HD-20 series with identical electrical and mechanical specifications. The primary difference is packaging: 1-106505-2 is supplied in Tray format, while 5-106505-2 is supplied in Bulk format. Both are ROHS3 Compliant and Active products. Selection between these two depends on packaging requirements and inventory management preferences.

Q: Why is the 8-1393480-1 listed as a substitute if it has a lower current rating?

A: The 8-1393480-1 meets all primary compatibility criteria for D-Sub 9-position receptacle connectors (connector style, type, positions, rows, shell size, mounting, termination, shell material, contact finish, and flammability rating). However, the current rating of 2.2A is substantially lower than the DEMM-9S-D (7.5A). This part is a valid substitute only for applications with reduced current requirements. Applications requiring 7.5A cannot use this part.

Q: Are there temperature limitations I should consider when substituting?

A: Yes. The DEMM-9S-D operates from -55°C to 150°C. The TE Connectivity 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. If your application requires operation above 105°C, only the DEMM-9S-D or 8-1393480-1 are suitable. If operation above 125°C is required, only the DEMM-9S-D is suitable.

Q: Does RoHS compliance affect my selection?

A: The DEMM-9S-D is RoHS non-compliant. If your application or regulatory environment requires RoHS compliance, you must select from the substitute parts: 1-106505-2, 5-106505-2, or 8-1393480-1, all of which are RoHS Compliant or ROHS3 Compliant. All parts maintain UL94 V-0 flammability certification.

Q: What is the difference in contact finish thickness between these parts?

A: The DEMM-9S-D specifies 50.0µin (1.27µm) gold contact finish thickness. The 1-106505-2 and 5-106505-2 specify 30.0µin (0.76µm). The 8-1393480-1 does not specify contact finish thickness. Thicker gold plating generally provides enhanced corrosion resistance and contact durability. Applications in corrosive environments may benefit from the DEMM-9S-D's thicker gold finish.

Q: Can I mix DEMM-9S-D and substitute parts in the same assembly?

A: All parts are mechanically and electrically compatible within the D-Sub 9-position receptacle category. However, mixing parts with different current ratings (7.5A, 6A, or 2.2A) in the same assembly requires verification that each connector is used in a circuit segment appropriate to its current rating. Mixing parts with different operating temperature ratings requires verification that each connector operates within its specified temperature range in its installed location.

Q: What packaging options are available?

A: The DEMM-9S-D is supplied in Bulk packaging (1041 pieces in stock). The 1-106505-2 is supplied in Tray packaging (1990 pieces in stock). The 5-106505-2 and 8-1393480-1 are supplied in Bulk packaging (999 and 1827 pieces in stock, respectively). Packaging selection depends on assembly process requirements and inventory management practices.
