Amphenol ICC 89074-141 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89074-141 is a 48-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 89074-141 carries an obsolete product status, which necessitates identification of active equivalent alternatives to ensure design continuity and procurement availability. The substitute part 89074-141LF provides functional equivalence while maintaining active product status and improved compliance posture.

Key Parameters

Substitute Part Grouping Explanation

The 89074-141LF qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Identical 48-position, 4-row header with 0.079" (2.00mm) pitch
• Electrical Characteristics: Matching 1A current rating and operating temperature range (-55°C to 125°C)
• Physical Interface: Through-hole mounting with press-fit termination ensures PCB compatibility
• Contact Properties: Gold plating at 30.0µin (0.76µm) thickness maintains electrical performance
• Reliability Standards: Both parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification

The primary distinction is product lifecycle status: 89074-141 is obsolete, while 89074-141LF is active. Additionally, 89074-141LF achieves RoHS compliance, whereas the original part does not.

Parameter Comparison

Engineering Selection Recommendations

The 89074-141LF is the appropriate selection for new designs and procurement activities. This part maintains complete electrical and mechanical compatibility with the obsolete 89074-141 while offering the following advantages:

• Active Product Status: Ensures long-term availability and manufacturer support
• RoHS Compliance: Meets current environmental and regulatory requirements for commercial and industrial applications
• Identical Electrical Performance: Maintains 1A current rating and full operating temperature specification
• Preserved Physical Interface: Through-hole press-fit termination and 2.00mm pitch ensure direct PCB compatibility without redesign

For existing designs currently specified with 89074-141, direct substitution with 89074-141LF requires no circuit modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can 89074-141LF be used as a direct replacement for 89074-141 in existing assemblies?

A: Yes. Both parts share identical connector configuration (48 positions, 4 rows, 2.00mm pitch), electrical ratings (1A, -55°C to 125°C), and physical mounting interface (through-hole, press-fit). No PCB modifications are required.

Q: What is the significance of the "LF" designation in 89074-141LF?

A: The "LF" suffix indicates lead-free construction, which correlates with RoHS compliance. The 89074-141LF meets current environmental regulations, whereas the original 89074-141 does not.

Q: Are there packaging differences between these parts?

A: Yes. The 89074-141 is supplied in bulk packaging, while 89074-141LF is packaged in tubes. This difference does not affect electrical or mechanical performance but may influence handling and storage procedures.

Q: Why is the original 89074-141 marked as obsolete?

A: Product obsolescence typically reflects manufacturer lifecycle decisions and the transition to compliant alternatives. The 89074-141LF represents the active equivalent within the Metral® series.

Q: Do both parts meet the same reliability and flammability standards?

A: Yes. Both the 89074-141 and 89074-141LF are rated UL94 V-0 for material flammability and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent reliability performance.
