Amphenol ICC 85853-192 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 85853-192 is a 60-position PCB header connector with male pins configured for through-hole mounting. This connector is part of the Metral® series and features press-fit termination with gold-plated contacts. The main part (85853-192) is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The substitute part 85853-192LF provides functional equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 85853-192 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 60 positions, 40 positions loaded, 5-row arrangement
• Electrical Specifications: 1A current rating, gold contact finish at 30.0µin thickness
• Mechanical Interface: 0.079" (2.00mm) pitch, through-hole mounting, press-fit termination
• Environmental Performance: Operating range -55°C to 125°C, UL94 V-0 flammability rating, MSL 1

The substitute part 85853-192LF maintains identical electrical and mechanical specifications while differing only in product status (active vs. obsolete) and color designation (natural/white vs. natural). Both parts share the same base product number (85853) and series designation (Metral®).

Parameter Comparison

Engineering Selection Recommendations

The 85853-192LF is the direct functional equivalent for the obsolete 85853-192. Selection between these parts should be based on the following factors:

Product Status: The 85853-192 is obsolete with limited remaining inventory (720 pcs). The 85853-192LF maintains active product status with higher current inventory (859 pcs), ensuring long-term availability for new designs and production runs.

Regulatory Compliance: The 85853-192LF carries RoHS Compliant certification and REACH Affected status, meeting current environmental regulations. The original part lists REACH Unaffected status, reflecting its obsolete classification. For applications subject to RoHS or REACH requirements, the 85853-192LF is the appropriate selection.

Packaging: The 85853-192LF is supplied in tube packaging, whereas the original part packaging is not specified. Verify packaging requirements for your assembly process.

Electrical and Mechanical Equivalence: Both parts are fully equivalent across all critical parameters including connector configuration, pitch, current rating, temperature range, and contact specifications. No functional differences exist between the parts.

Frequently Asked Questions (FAQ)

Q: Can the 85853-192LF be used as a direct replacement for the 85853-192?

A: Yes. The 85853-192LF is electrically and mechanically equivalent to the 85853-192 across all specified parameters. Both connectors feature identical 60-position configuration, 0.079" pitch, 1A current rating, and operating temperature range. The primary difference is product status (active vs. obsolete) and regulatory compliance certifications.

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

A: The "LF" suffix typically indicates lead-free compliance in connector part numbering. The 85853-192LF carries RoHS Compliant certification, whereas the original 85853-192 does not specify this status.

Q: Are there differences in contact finish between these parts?

A: No. Both parts feature gold-plated contacts with identical finish thickness of 30.0µin (0.76µm). Contact performance and reliability are equivalent.

Q: What packaging format is the 85853-192LF supplied in?

A: The 85853-192LF is supplied in tube packaging. Confirm this packaging format is compatible with your receiving and assembly processes.

Q: Why is the original 85853-192 listed as obsolete?

A: The 85853-192 has been superseded by the 85853-192LF, which maintains identical functionality while meeting current regulatory requirements. Amphenol ICC has transitioned production to the active equivalent part.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.

Q: Can I mix 85853-192 and 85853-192LF connectors in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, verify that your design documentation and procurement specifications permit mixing obsolete and active parts. For consistency and long-term supportability, standardizing on the 85853-192LF is recommended.
