Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 205720-2 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 1-205720-0 qualifies as a direct equivalent because it maintains identical specifications in the following key areas:

Electrical Parameters:

• 104-position connector configuration
• 0.150" (3.81mm) pitch spacing
• Gold contact finish with flash thickness
• Wire wrap termination method
• UL94 V-0 flammability rating
• Operating temperature range of -55°C to 150°C

Mechanical Parameters:

• Panel mount installation method
• Female socket receptacle type
• Black housing color
• Mating guide feature
• Series M classification

The primary distinction between the main part and substitute is product status and packaging. The 205720-2 is obsolete, while 1-205720-0 maintains active product status with tray packaging, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-205720-0 is the direct substitute for the obsolete 205720-2 based on complete electrical and mechanical parameter equivalence. Selection of the substitute part is supported by the following engineering factors:

Product Status: The 1-205720-0 maintains active product status with TE Connectivity, ensuring continued manufacturing support, quality assurance, and supply chain availability. The 205720-2 is classified as obsolete and subject to discontinuation.

Compliance and Certifications: Both parts carry identical compliance designations including UL94 V-0 flammability rating, EAR99 export classification, and HTSUS code 8536.69.4030. No compliance gaps exist between the main part and substitute.

Packaging and Logistics: The substitute part is supplied in tray packaging, which provides standardized handling and storage benefits for production environments. This represents an improvement over the unspecified packaging of the obsolete part.

Functional Equivalence: All 104 positions are loaded in both configurations. The wire wrap termination, gold contact finish, panel mount design, and mating guide feature are preserved across both parts, ensuring drop-in compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 1-205720-0 be used as a direct replacement for the 205720-2 in existing designs?

A: Yes. The 1-205720-0 is electrically and mechanically identical to the 205720-2 across all specified parameters.
