TE Connectivity Erni 423561 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 423561 is a D-Sub receptacle connector with 25 positions, configured for Insulation Displacement Contact (IDC) termination. This connector is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure component availability for new production and field service applications.

The original part functions as a female socket receptacle in D-Sub configurations, supporting signal-level connections with IDC discrete wire termination. Due to its obsolete status, substitute parts from the active TE Connectivity AMP Connectors AMPLIMITE HDE-20 series provide functional equivalence while offering current manufacturing support and compliance certifications.

Connector Configuration Parameters:

• Connector Style: D-Sub
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Contact Type: Signal

Termination & Assembly Parameters:

• Termination Method: IDC, Discrete Wire
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Cable Side, Male Jackscrew (4-40)

Material & Environmental Parameters:

• Shell Material, Finish: Steel, Tin Plated
• Contact Material: Phosphor Bronze
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 250V
• Material Flammability Rating: UL94 V-0

The substitute parts 1-747947-5 and 1-747948-6 are both members of the TE Connectivity AMP Connectors AMPLIMITE HDE-20 series. Part 1-747947-5 is a direct functional equivalent as a 25-position receptacle (female sockets). Part 1-747948-6 is a complementary plug connector (male pins) within the same series, providing mating pair functionality for complete D-Sub assemblies.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1-747947-5

Part 1-747947-5 is the direct functional equivalent for applications requiring a 25-position D-Sub receptacle connector. This part maintains identical electrical and mechanical specifications to the obsolete 423561, including connector configuration, termination method, shell material, contact materials, and environmental ratings. The part is classified as active with current manufacturing support from TE Connectivity AMP Connectors.

Compliance advantages of 1-747947-5 include RoHS compliance certification and EAR99 export classification, providing regulatory alignment for new designs and production environments. Inventory availability of 828 pieces supports both immediate component procurement and long-term supply chain planning.

Complementary Substitute: 1-747948-6

Part 1-747948-6 functions as the mating plug connector within the AMPLIMITE HDE-20 series. This part is specified for applications requiring complete D-Sub cable assemblies or connector pairs. The part shares identical shell size, position count, termination method, and environmental specifications with the receptacle equivalent.

Wire gauge specification for 1-747948-6 is 22-26 AWG, compared to 26-30 AWG for the receptacle 1-747947-5. This difference reflects standard industry practice for male pin contacts versus female socket contacts and does not affect substitution compatibility when properly matched in assembly applications.

Both substitute parts carry active product status, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can 1-747947-5 directly replace the obsolete 423561 in existing designs?

A: Yes. Part 1-747947-5 maintains identical electrical and mechanical parameters across all critical substitution criteria: 25-position D-Sub receptacle configuration, IDC discrete wire termination, shell size 3 (DB, B), steel tin-plated housing, phosphor bronze gold-plated contacts, -55°C to 105°C operating temperature, and 250V voltage rating. The part is functionally interchangeable for receptacle applications.

Q: What is the relationship between 1-747947-5 and 1-747948-6?

A: These parts form a mating pair within the TE Connectivity AMP Connectors AMPLIMITE HDE-20 series. Part 1-747947-5 is a receptacle (female sockets) and 1-747948-6 is a plug (male pins). Both share identical shell configuration, position count, and termination method. They are specified together for complete D-Sub cable assemblies and connector pairs.

Q: Are there wire gauge differences between the substitute parts?

A: Yes. Part 1-747947-5 (receptacle) specifies 26-30 AWG wire gauge, while 1-747948-6 (plug) specifies 22-26 AWG. This difference is standard for D-Sub connector design, where male pin contacts accommodate slightly heavier gauge wire than female socket contacts. Wire gauge selection must match the specific contact type and termination requirements of each connector position.

Q: What compliance certifications apply to the substitute parts?

A: Both 1-747947-5 and 1-747948-6 are RoHS Compliant and carry EAR99 export classification. Both parts meet UL94 V-0 material flammability rating and maintain Moisture Sensitivity Level (MSL) 1 (Unlimited). These certifications support regulatory compliance for new production and design implementations.

Q: Is the obsolete 423561 still available for procurement?

A: Current inventory shows 732 pieces of the original 423561 in stock as new original components. However, due to obsolete product status, long-term availability cannot be assured. Transition to active substitute parts 1-747947-5 or 1-747948-6 is recommended for new designs and ongoing production requirements.

Q: What is the packaging format for substitute parts?

A: Both 1-747947-5 and 1-747948-6 are supplied in Bulk packaging format, consistent with standard D-Sub connector distribution for production and assembly applications.
