TE Connectivity 1-557089-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-557089-3 is an 80-position receptacle connector with free hanging (in-line) mounting and IDC termination. This connector features outer shroud contacts, gold-plated contact finish, and is part of the CHAMP .050 I series. The part is classified as obsolete, making identification of active equivalent components necessary for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-557089-3 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• 80-position connector configuration
• 2-row arrangement
• IDC (Insulation Displacement Contact) termination technology
• Gold contact finish material

Mechanical Specifications:

• Free hanging (in-line) mounting orientation
• Outer shroud contact style
• CHAMP .050 I series compatibility

Environmental Specifications:

• Moisture Sensitivity Level 1 (Unlimited)

The substitute part 1734098-8 maintains full equivalence across all electrical and mechanical parameters. The primary distinction between the main part and substitute is product status (obsolete versus active) and packaging configuration (bulk versus tube).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1734098-8 is the direct equivalent for the obsolete 1-557089-3. Both components share identical electrical and mechanical specifications across all critical parameters including connector configuration, termination method, mounting style, and contact materials.

Product Status Consideration: The 1734098-8 maintains active product status with TE Connectivity, ensuring ongoing availability and supply chain continuity. The 1-557089-3 is classified as obsolete and should not be specified for new designs or long-term procurement strategies.

Compliance Consideration: The 1734098-8 is ROHS3 compliant, whereas the 1-557089-3 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 1734098-8 is the appropriate selection.

Packaging Consideration: The 1734098-8 is supplied in tube packaging, while the 1-557089-3 was supplied in bulk packaging. Packaging differences do not affect electrical or mechanical performance and are determined by procurement volume and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1734098-8 directly replace the 1-557089-3 in existing applications?

A: Yes. The 1734098-8 is electrically and mechanically equivalent to the 1-557089-3. Both connectors feature identical 80-position, 2-row configurations with IDC termination, free hanging mounting, and gold-plated outer shroud contacts within the CHAMP .050 I series.

Q: What is the primary reason to transition from 1-557089-3 to 1734098-8?

A: The 1-557089-3 is classified as obsolete. The 1734098-8 is an active product with TE Connectivity, providing assured long-term availability and supply chain reliability. Additionally, the 1734098-8 is ROHS3 compliant, addressing regulatory requirements not met by the obsolete part.

Q: Are there differences in contact finish between these parts?

A: Both parts feature gold contact finish. The 1-557089-3 specifies 30.0µin (0.76µm) contact finish thickness, while the 1734098-8 specifies flash gold plating. Both finishes are suitable for IDC termination applications and provide equivalent electrical performance.

Q: Does packaging affect connector performance or compatibility?

A: No. The 1-557089-3 (bulk packaging) and 1734098-8 (tube packaging) are functionally identical. Packaging differences relate only to handling, storage, and procurement logistics and do not impact electrical or mechanical performance.

Q: Are both parts suitable for the same environmental conditions?

A: Yes. Both the 1-557089-3 and 1734098-8 are rated at Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental performance across moisture exposure conditions.

Q: What is the inventory status for the substitute part?

A: The 1734098-8 has 1017 pieces in new original stock, providing immediate availability for procurement. The 1-557089-3 has 853 pieces in stock but is obsolete and should not be specified for new applications.
