Amphenol ICC 89073-181 24-Position PCB Header Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89073-181 is a 24-position PCB header connector with male pins designed for through-hole mounting applications. This connector belongs to the Metral® series and features a 2.00mm pitch configuration with 4 rows of contacts. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning. The 89073-181LF represents the active production equivalent with enhanced compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 89073-181 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with male pins, 24 positions, 4-row arrangement
• Electrical Interface: 2.00mm pitch, 1A current rating, press-fit termination
• Physical Mounting: Through-hole PCB mounting capability
• Environmental & Safety Compliance: UL94 V-0 flammability rating, -55°C to 125°C operating range
• Contact Metallurgy: Gold finish at 30.0µin thickness

The 89073-181LF qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is product status transition from obsolete to active production, accompanied by improved regulatory compliance (RoHS Compliant, REACH Affected versus RoHS non-compliant status of the original part).

Parameter Comparison

Engineering Selection Recommendations

The 89073-181LF is the appropriate selection for new designs and ongoing procurement requirements. This substitute maintains complete electrical and mechanical compatibility with the original 89073-181 while offering the following advantages:

• Active Production Status: The 89073-181LF is in active production, ensuring long-term availability and supply chain stability compared to the obsolete 89073-181.
• Regulatory Compliance: RoHS Compliant status aligns with current environmental regulations and procurement requirements in regulated industries.
• REACH Compliance: REACH Affected designation indicates full regulatory documentation and traceability support.
• Standardized Packaging: Tube packaging provides consistent handling and inventory management.

For legacy systems currently using the 89073-181, direct substitution with the 89073-181LF requires no design modifications, as all functional parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can the 89073-181LF be used as a direct replacement for the 89073-181 in existing designs?

A: Yes. The 89073-181LF is electrically and mechanically identical to the 89073-181. All critical parameters—connector type, position count, pitch, current rating, operating temperature range, and contact finish—are equivalent. No PCB layout or schematic modifications are required.

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

A: The "LF" suffix indicates lead-free compliance. The 89073-181LF meets RoHS requirements and is REACH Affected, reflecting compliance with current environmental and hazardous substance regulations.

Q: Are there packaging differences between these parts?

A: The 89073-181 packaging is not specified in available documentation. The 89073-181LF is supplied in tube packaging, which is standard for production components and provides organized storage and handling.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: connector type (header, male pins), position count (24), pitch (2.00mm), row configuration (4 rows), mounting method (through-hole), termination type (press-fit), contact finish (gold, 30.0µin), current rating (1A), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0).

Q: Is the 89073-181LF suitable for high-reliability applications?

A: The 89073-181LF meets UL94 V-0 flammability requirements and operates across the -55°C to 125°C temperature range, supporting applications with standard environmental and thermal demands. Specific high-reliability qualifications should be confirmed against application requirements.

Q: What is the current inventory status?

A: The 89073-181 has 1,061 pieces in stock (obsolete status). The 89073-181LF has 682 pieces in stock (active production status). For new procurement, the 89073-181LF is the recommended source.
