Amphenol ICC 89073-183 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89073-183 is a 24-position PCB header connector from the Metral® series, designed for through-hole mounting applications. This connector features male pins with press-fit termination and gold-plated contacts rated for 1A continuous current operation across an extended temperature range of -55°C to 125°C.

The 89073-183 carries an obsolete product status, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The substitute part 89073-183LF provides functional equivalence while maintaining active product availability and improved compliance posture.

Key Parameters

Substitute Part Grouping Explanation

The 89073-183LF qualifies as a direct functional substitute based on the following critical parameters:

• Connector Configuration: Identical 24-position, 4-row header with 0.079" (2.00mm) pitch
• Electrical Performance: Matching 1A current rating and gold contact finish specification
• Mechanical Interface: Through-hole mounting with press-fit termination ensures PCB compatibility
• Environmental Ratings: Identical operating temperature range (-55°C to 125°C) and UL94 V-0 flammability classification
• Moisture Sensitivity: Both parts classified as MSL 1 with unlimited shelf life

The primary distinction between these parts is product status and regulatory compliance. The 89073-183LF transitions from obsolete to active status and achieves RoHS compliance, making it the preferred selection for new designs and production continuity.

Parameter Comparison

Engineering Selection Recommendations

The 89073-183LF is the appropriate selection for all new designs and production applications requiring a 24-position, 2.00mm pitch PCB header connector. This part maintains complete electrical and mechanical compatibility with the obsolete 89073-183 while providing the following advantages:

• Active Product Status: Ensures long-term availability and supply chain continuity
• RoHS Compliance: Meets current regulatory requirements for lead-free manufacturing and environmental standards
• REACH Compliance: Addresses chemical substance restrictions in manufacturing and distribution
• Improved Packaging: Tube packaging provides better component protection and handling efficiency compared to bulk packaging

Existing designs currently utilizing the 89073-183 can transition to the 89073-183LF without modification to PCB layouts, assembly processes, or mating connector specifications. The identical pitch, position count, mounting method, and electrical ratings ensure direct interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the 89073-183 and 89073-183LF mechanically interchangeable?

A: Yes. Both connectors feature identical 24-position configuration, 0.079" (2.00mm) pitch, 4-row layout, and through-hole press-fit termination. PCB footprints and mating connector interfaces are identical.

Q: What is the difference between these two part numbers?

A: The 89073-183LF is the active production equivalent of the obsolete 89073-183. The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and packaging format (tube vs. bulk). All electrical and mechanical specifications remain identical.

Q: Can I use the 89073-183LF as a direct replacement in existing assemblies?

A: Yes. The 89073-183LF provides complete functional equivalence and can be used as a direct replacement without design modifications or assembly process changes.

Q: Why should I transition from the 89073-183 to the 89073-183LF?

A: The 89073-183 is obsolete and subject to supply discontinuation. The 89073-183LF ensures ongoing availability, meets current RoHS and REACH regulatory requirements, and is the recommended part for all new production.

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

A: No. Both parts share identical current rating (1A), contact finish specification (gold, 30.0µin), operating temperature range (-55°C to 125°C), and flammability classification (UL94 V-0).

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance, reflecting the transition to environmentally compliant manufacturing standards.
