TE Connectivity 205720-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205720-1 is a 104-position receptacle connector with female sockets designed for panel mount applications. This backplane connector features wire wrap termination, gold-plated contacts, and a 0.150" (3.81mm) pitch configuration. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 205720-1 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain the following specifications without deviation:

• Connector Configuration: 104-position receptacle with female sockets
• Pitch Specification: 0.150" (3.81mm) center-to-center spacing
• Mounting Interface: Panel mount configuration
• Termination Method: Wire wrap termination
• Contact Material: Gold plating with flash thickness
• Environmental Rating: UL94 V-0 flammability classification
• Temperature Performance: -55°C to 150°C operating range
• Moisture Sensitivity: MSL 1 (Unlimited)
• Series Designation: M series

The substitute part 205720-9 meets all these criteria and is manufactured by the same supplier, ensuring mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 205720-9 is the direct active substitute for the obsolete 205720-1. Both components share identical electrical and mechanical specifications across all critical parameters, including connector configuration, pitch, mounting interface, termination method, contact material, and environmental ratings.

The primary distinction between these parts is product status and regulatory compliance. The 205720-1 is classified as obsolete and carries RoHS non-compliant status. The 205720-9 maintains full compatibility with the original design while offering ROHS3 compliance, making it suitable for applications subject to current environmental regulations.

For new designs or system upgrades, the 205720-9 should be specified. For legacy system maintenance where the original 205720-1 is required, the 205720-9 provides direct functional equivalence with enhanced compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the 205720-9 be used as a direct replacement for the 205720-1 in existing assemblies?

A: Yes. The 205720-9 is electrically and mechanically identical to the 205720-1 across all specified parameters. Both connectors feature 104 positions, 0.150" pitch, panel mount configuration, wire wrap termination, and identical contact materials and environmental ratings. Direct substitution is supported.

Q: What is the difference between the 205720-1 and 205720-9?

A: The primary differences are product status and regulatory compliance. The 205720-1 is obsolete and RoHS non-compliant. The 205720-9 is an active product with ROHS3 compliance. All electrical and mechanical specifications remain identical.

Q: Are there any compatibility concerns when switching from 205720-1 to 205720-9?

A: No compatibility concerns exist. Both parts are manufactured by TE Connectivity AMP Connectors within the M series and maintain identical specifications for connector type, position count, pitch, mounting method, termination, contact finish, color, temperature range, and flammability rating.

Q: What is the pitch specification for these connectors?

A: Both the 205720-1 and 205720-9 feature a 0.150" (3.81mm) pitch, representing the center-to-center spacing between adjacent contact positions.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both connectors are rated for operation across the -55°C to 150°C temperature range and carry a UL94 V-0 flammability classification, suitable for demanding thermal environments.

Q: What termination method is used for these connectors?

A: Both the 205720-1 and 205720-9 utilize wire wrap termination, a solderless connection method suitable for automated assembly and field maintenance applications.

Q: Is moisture sensitivity a concern for these connectors?

A: No. Both connectors carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
