Amphenol ICC 89074-155 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89074-155 is a 48-position connector header with male pins designed for through-hole PCB mounting. This component belongs to the Metral® series of backplane connectors and features press-fit termination with gold-plated contacts. The 89074-155 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The substitute 89074-155LF provides functional continuity with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

The 89074-155LF qualifies as a direct substitute based on identical electrical and mechanical parameters:

• Position Count & Pitch: Both parts maintain 48 positions at 0.079" (2.00mm) pitch in a 4-row configuration
• Connector Type & Termination: Both are male pin headers with press-fit termination
• Contact Specifications: Identical gold plating thickness (30.0µin) and current rating (1A)
• Environmental Ratings: Both meet UL94 V-0 flammability and operate across -55°C to 125°C
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is product status and compliance: 89074-155 is obsolete with RoHS non-compliant status, while 89074-155LF is active with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 89074-155LF is the appropriate selection for new designs and ongoing production:

• Active Product Status: The 89074-155LF maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• RoHS Compliance: The 89074-155LF meets RoHS requirements, satisfying regulatory mandates for new equipment placed on the market in regulated jurisdictions
• Functional Equivalence: All electrical and mechanical parameters remain identical, ensuring direct PCB compatibility without design modification
• Packaging: The 89074-155LF is supplied in tube packaging, providing organized component handling for production environments

For legacy systems currently using 89074-155, the 89074-155LF provides a direct replacement without performance degradation or circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can 89074-155LF be used as a direct replacement for 89074-155 on existing PCBs?

A: Yes. Both parts share identical position count (48), pitch (0.079"), row configuration (4), connector type (male header), mounting method (through-hole), and electrical ratings (1A, -55°C to 125°C). No PCB layout modification is required.

Q: What is the significance of the "LF" suffix in 89074-155LF?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This reflects the manufacturing process change from the obsolete 89074-155.

Q: Are there any compatibility concerns between these two part numbers?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable. The primary differences are product lifecycle status and regulatory compliance.

Q: What packaging format is each part supplied in?

A: The 89074-155 is supplied in bulk packaging. The 89074-155LF is supplied in tube packaging, which provides better component organization and handling in production workflows.

Q: Why is 89074-155 classified as obsolete?

A: The 89074-155 has been superseded by the 89074-155LF, which offers RoHS compliance and active manufacturing support. Amphenol ICC has transitioned production to the compliant variant.
