DEMD9SD D-Sub 9 Position Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DEMD9SD 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 actively produced and maintains 920 units in current inventory stock. The DEMD9SD serves as a standard interface component in applications requiring robust D-Sub connectivity with gold-plated contacts and UL94 V-0 flammability compliance.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: connector style (D-Sub), type (receptacle with female sockets), position count (9), row configuration (2 rows), shell size (1/DE/E), mounting method (right-angle solder), and contact material specifications. Substitutes must maintain compatibility within these defined parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DEMD9SD are identified through strict alignment with the following core parameters:

Primary Matching Criteria:

• Connector style: D-Sub receptacle
• Position count: 9 positions
• Row configuration: 2 rows
• Shell size: 1 (DE, E)
• Mounting: Right-angle, through-hole, solder termination
• Contact type: Signal, female sockets
• Contact finish: Gold plated

Identified Substitutes:

1. 1-106505-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) - Tray packaged variant with mating-side female screwlock flange and board lock feature
2. 5-106505-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) - Bulk packaged variant with unthreaded housing/shell flange
3. 8-1393480-1 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) - Bulk packaged variant with board lock feature and gray color

All three substitutes maintain the core D-Sub 9-position receptacle architecture with right-angle solder termination and gold contact finish. Variations exist in flange design, packaging format, current rating, and operating temperature range, which are detailed in the parameter comparison table.

Engineering Selection Recommendations

DEMD9SD (Primary Part): Remains the specified component when yellow chromate plated zinc shell finish is required and RoHS non-compliance is acceptable. Supports the full 7.5A current rating and extended operating temperature range to 125°C. Active production status ensures continued availability.

1-106505-2 (TE Connectivity AMPLIMITE HD-20): Suitable for applications requiring ROHS3 compliance and tin-plated steel shell finish. Provides 6A current rating with -55°C to 105°C operating range. Mating-side female screwlock flange and board lock feature offer enhanced mechanical retention. Tray packaging supports controlled component handling.

5-106505-2 (TE Connectivity AMPLIMITE HD-20): Functionally equivalent to 1-106505-2 with identical electrical and thermal specifications. Bulk packaging reduces per-unit cost. Unthreaded housing/shell flange eliminates threaded fastener requirements. ROHS3 compliant.

8-1393480-1 (TE Connectivity AMPLIMITE HD-20): Applicable when gray connector color is acceptable and RoHS compliance is required. Maintains full -55°C to 125°C operating temperature range matching DEMD9SD. Current rating of 2.2A limits use to lower-power signal applications. Board lock feature provides mechanical stability. Copper alloy contact material aligns with DEMD9SD specification.

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. Selection between substitutes depends on specific compliance requirements, current capacity needs, thermal operating range, and mechanical flange design preferences.

Frequently Asked Questions (FAQ)

Q: Can 1-106505-2, 5-106505-2, and 8-1393480-1 be used interchangeably with DEMD9SD?

A: These parts share the core D-Sub 9-position receptacle architecture with right-angle solder termination and gold contact finish. However, differences in current rating, operating temperature range, shell finish, and flange design require application-specific evaluation. The 8-1393480-1 current rating of 2.2A is significantly lower than DEMD9SD (7.5A) and 1-106505-2/5-106505-2 (6A), limiting its use to lower-power applications.

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

A: Both parts are TE Connectivity AMPLIMITE HD-20 series connectors with identical electrical specifications (6A current rating, -55°C to 105°C operating range). The primary difference is packaging: 1-106505-2 is supplied in trays, while 5-106505-2 is supplied in bulk. Additionally, 1-106505-2 features a mating-side female screwlock (4-40) flange, while 5-106505-2 has an unthreaded housing/shell flange.

Q: Does the shell finish difference affect electrical performance?

A: Shell finish (yellow chromate plated zinc on DEMD9SD versus tin plated on TE Connectivity substitutes) does not affect electrical signal integrity or contact performance. The finish provides corrosion resistance and environmental protection. Selection depends on compliance requirements and application environment.

Q: Are all substitute parts RoHS compliant?

A: DEMD9SD is RoHS non-compliant. All three substitute parts (1-106505-2, 5-106505-2, and 8-1393480-1) are RoHS compliant, with 1-106505-2 and 5-106505-2 meeting ROHS3 standards. Applications requiring RoHS compliance must use one of the TE Connectivity substitutes.

Q: What is the significance of the current rating differences?

A: DEMD9SD supports 7.5A per contact, while 1-106505-2 and 5-106505-2 support 6A, and 8-1393480-1 supports 2.2A. Applications requiring current levels above 6A must use DEMD9SD. Applications with current requirements below 2.2A can use any substitute. Current rating determines maximum safe operating current without exceeding contact temperature limits.

Q: Can 8-1393480-1 be used as a direct replacement for DEMD9SD?

A: 8-1393480-1 is not a direct replacement due to significantly reduced current rating (2.2A versus 7.5A) and different contact material (copper alloy versus phosphor bronze in other TE substitutes). However, it maintains the full -55°C to 125°C operating temperature range and copper alloy contact material matching DEMD9SD. Use is limited to applications with current requirements below 2.2A.

Q: What mounting differences exist between these connectors?

A: DEMD9SD and 1-106505-2/5-106505-2 specify panel mount with through-hole right-angle installation. 8-1393480-1 specifies through-hole right-angle installation without explicit panel mount designation. All three use solder termination. Flange design varies: DEMD9SD uses female screwlock (4-40), 1-106505-2 uses female screwlock (4-40), 5-106505-2 uses unthreaded housing/shell, and 8-1393480-1 uses female screwlock (4-40) with board lock feature.

Q: How do dielectric material differences impact connector performance?

A: DEMD9SD uses polycyclohexylenedimethylene terephthalate (PCT), while TE Connectivity substitutes use polyester glass-filled or polybutylene terephthalate (PBT) materials. All materials meet UL94 V-0 flammability requirements. Dielectric material selection affects mechanical strength, thermal stability, and moisture absorption characteristics. Material differences do not affect electrical signal performance for standard D-Sub applications.
