TE Connectivity Erni 423559 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 423559 is a D-Sub receptacle connector with 9 positions, designed for IDC (Insulation Displacement Contact) termination. This connector is classified as obsolete and is no longer in active production. Due to its obsolete status, sourcing original units becomes increasingly difficult. Identifying qualified substitute parts ensures design continuity and maintains supply chain reliability for applications requiring 9-position D-Sub receptacle functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 423559 is based on strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Connector Category: D-Sub, D-Shaped Connectors
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Termination Method: IDC, Discrete Wire
• Shell Size/Connector Layout: 1 (DE, E)

The substitute part 1-747943-5 from TE Connectivity AMP Connectors satisfies all critical parameters. This part maintains functional equivalence while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP 1-747943-5

The part 1-747943-5 is the manufacturer-recommended substitute for the obsolete TE Connectivity Erni 423559. This substitution is supported by:

• Identical connector category, type, and position count
• Matching termination method (IDC, Discrete Wire)
• Identical shell size and connector layout (1 DE, E)
• Active product status with established supply chain
• RoHS compliance certification
• Higher inventory availability (831 units vs. 681 units)
• Documented compliance with EAR99 export classification

The substitute part operates within the same electrical and mechanical parameters required for 9-position D-Sub receptacle applications. The transition from the obsolete Erni series to the active AMPLIMITE HDE-20 series maintains functional compatibility while ensuring long-term component availability.

Frequently Asked Questions (FAQ)

Q: What makes the TE Connectivity AMP 1-747943-5 a direct substitute for the Erni 423559?

A: Both connectors share identical core specifications: 9-position D-Sub receptacle configuration, female socket contacts, IDC termination capability, and shell size 1 (DE, E) layout. These parameters define functional equivalence for D-Sub connector applications.

Q: Why is the Erni 423559 classified as obsolete?

A: The Erni 423559 has reached end-of-life status in TE Connectivity's product portfolio. The AMPLIMITE HDE-20 series (including part 1-747943-5) represents the current active alternative within TE Connectivity's D-Sub connector lineup.

Q: Are there any electrical performance differences between these parts?

A: The substitute part 1-747943-5 provides documented specifications including 250V voltage rating, -55°C to 105°C operating temperature range, and gold-plated contacts. The original Erni 423559 specifications for these parameters were not provided in the available documentation. Both parts support 26-30 AWG wire gauges for IDC termination.

Q: What is the packaging difference?

A: The substitute part 1-747943-5 is supplied in Bulk packaging. Original packaging information for the Erni 423559 was not specified in available data.

Q: Does the substitute part meet current compliance standards?

A: Yes. The TE Connectivity AMP 1-747943-5 is RoHS compliant and classified under ECCN EAR99. The part carries Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life under standard storage conditions.

Q: Can I use the substitute part in existing designs without modification?

A: The substitute part maintains mechanical and electrical compatibility with the original Erni 423559 due to identical connector type, position count, and termination method. No design modifications are required for direct substitution in applications using 9-position D-Sub receptacle connectors with IDC termination.
