Amphenol ICC 85854-147 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 85854-147 is a 120-position PCB connector header with male pins designed for through-hole mounting applications. This component belongs to the Metral® series of backplane connectors and features press-fit termination with gold-plated contacts rated for 1A current at operating temperatures between -55°C and 125°C.

The 85854-147 carries an obsolete product status, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The substitute part 85854-147LF provides functional continuity while offering current product availability and improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

The 85854-147LF qualifies as a direct substitute for the 85854-147 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector position count: 120 positions with 36 positions loaded
• Pitch specification: 0.079" (2.00mm)
• Row configuration: 5 rows
• Connector type and gender: Header with male pins
• Mounting method: Through-hole PCB mounting
• Termination style: Press-fit contact system
• Contact material and finish: Gold plating at 30.0µin thickness
• Current capacity: 1A rating
• Temperature operating range: -55°C to 125°C
• Flammability compliance: UL94 V-0

The primary distinction between these parts is product lifecycle status and regulatory compliance posture, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 85854-147LF is the appropriate selection for new designs and ongoing procurement activities. This part maintains complete electrical and mechanical compatibility with the obsolete 85854-147 while offering the following advantages:

Active product status ensures long-term availability and manufacturer support through standard distribution channels. RoHS compliance aligns with current environmental regulations and supply chain requirements for regulated industries. REACH compliance status reflects current chemical substance management standards applicable to European and global markets.

For legacy systems currently using the 85854-147, the 85854-147LF provides direct substitution without circuit redesign or PCB layout modification. The identical pitch, position count, row configuration, and contact specifications ensure mechanical and electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 85854-147LF be used as a direct replacement for the 85854-147 in existing assemblies?

A: Yes. All electrical and mechanical parameters are identical, including connector geometry, contact specifications, current rating, and temperature range. No circuit or layout modifications are required.

Q: What is the significance of the "LF" suffix in the part number 85854-147LF?

A: The "LF" designation indicates lead-free construction, reflecting RoHS compliance. This is the primary technical distinction between the two part numbers.

Q: Are there packaging differences between these parts?

A: The 85854-147 is supplied in bulk packaging, while the 85854-147LF is packaged in tubes. Both contain identical connector components; packaging selection depends on procurement and handling requirements.

Q: Does the RoHS compliance of the 85854-147LF affect performance in high-temperature applications?

A: No. Both parts maintain identical operating temperature specifications of -55°C to 125°C. RoHS compliance does not alter thermal performance characteristics.

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

A: No. Current rating (1A), contact finish (gold at 30.0µin), flammability rating (UL94 V-0), and all other electrical specifications are identical.

Q: What is the practical implication of the 36 loaded positions within the 120-position connector?

A: The connector is manufactured with 120 total position cavities, but only 36 positions are populated with contacts. This configuration allows for future expansion or selective contact utilization within the same connector footprint.
