A-DD 09 B-2 Equivalent & Substitute Parts

Part Overview

The A-DD 09 B-2 is a 9-position D-Sub stacked connector manufactured by Assmann WSW Components, configured as a plug with male pins and receptacle with female sockets in a right-angle through-hole mounting configuration. This connector is designed for signal applications with a current rating of 3A and voltage rating of 250V, operating across a temperature range of -55°C to 105°C.

The A-DD 09 B-2 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the A-DD 09 B-2 is determined by strict equivalence across the following critical parameters:

• Connector style: D-Sub - Stacked configuration
• Position count and row configuration: 9 positions, 2 rows
• Shell size and layout: 1 (DE, E) for both plug and receptacle
• Connector type: Plug with male pins and receptacle with female sockets
• Mounting configuration: Through-hole, right-angle orientation
• Termination method: Solder
• Operating temperature range: -55°C to 105°C
• Material flammability: UL94 V-0 compliance
• Contact finish: Gold plating

The substitute part 179-009-413R491 manufactured by NorComp Inc. meets all these critical parameters. While the substitute exhibits differences in shell material finish (nickel plated versus tin plated), current rating (5A versus 3A), and dielectric material composition, these represent improvements or alternative specifications that do not prevent functional substitution in the original application context.

Parameter Comparison

Engineering Selection Recommendations

The 179-009-413R491 from NorComp Inc. is the primary substitute for the obsolete A-DD 09 B-2. This recommendation is based on the following engineering factors:

The substitute part maintains full mechanical and electrical compatibility across all critical connector parameters, including position count, shell size, connector type, mounting configuration, and termination method. Both parts operate across the identical temperature range of -55°C to 105°C and meet UL94 V-0 flammability requirements.

The substitute part carries active product status, ensuring ongoing availability and supply chain support. The 179-009-413R491 is RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

The substitute exhibits a higher current rating (5A versus 3A), which provides additional electrical capacity margin for the application. The nickel-plated shell finish on the substitute offers equivalent corrosion resistance compared to the tin-plated finish of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 179-009-413R491 be used as a direct replacement for the A-DD 09 B-2 in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, shell size, position count, connector type, and mounting configuration. Both parts use solder termination and operate across the same temperature range with equivalent flammability ratings.

Q: What is the difference in current rating between these parts?

A: The A-DD 09 B-2 is rated for 3A, while the 179-009-413R491 is rated for 5A. The higher rating on the substitute part does not create compatibility issues; it represents increased electrical capacity that is backward compatible with applications designed for 3A operation.

Q: Are there packaging differences between the original and substitute part?

A: The A-DD 09 B-2 packaging specification is not provided in the available data. The 179-009-413R491 is supplied in tray packaging. Packaging format does not affect connector functionality or mechanical compatibility.

Q: What is the significance of the shell material finish difference?

A: The original part features a tin-plated steel shell, while the substitute features a nickel-plated steel shell. Both finishes provide corrosion protection and electrical conductivity suitable for signal connector applications. Nickel plating offers equivalent or superior environmental resistance in standard operating conditions.

Q: Does the substitute part meet current regulatory compliance standards?

A: Yes. The 179-009-413R491 is RoHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Q: Are there any mechanical mounting differences?

A: The substitute part supports both board edge and through-hole mounting options, while the original part specifies through-hole, right-angle mounting only. This expanded mounting capability does not affect compatibility when used in the original through-hole configuration.
