Amphenol ICC 55444-101 Backplane Connector Header

Part Overview

The Amphenol ICC 55444-101 is a 60-position Metral® series backplane connector header designed for through-hole PCB mounting with solder termination. This component features male pins configured in a 5-row by 12-column layout with 0.079" (2.00mm) pitch spacing and board guide features for alignment during assembly.

The 55444-101 is classified as obsolete product status. Locating equivalent substitute parts is necessary to support ongoing system maintenance, repair, and production requirements where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 55444-101 is determined by strict equivalence across the following critical parameters:

• Connector type: Header, Male Pins
• Number of positions: 60
• Pitch spacing: 0.079" (2.00mm)
• Number of rows: 5
• Number of columns: 12
• Mounting type: Through Hole
• Termination method: Solder
• Series family: Metral®
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 55444-101LF meets all these criteria and is manufactured by the same supplier (Amphenol ICC). The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 55444-101LF is the direct substitute for the obsolete 55444-101. Both components share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, row/column configuration, mounting method, and termination type.

The 55444-101LF offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the 55444-101LF achieves RoHS compliance, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection of the 55444-101LF is appropriate for new designs, production restocking, and field replacement applications where the original 55444-101 is no longer available.

Frequently Asked Questions (FAQ)

Q: Are the 55444-101 and 55444-101LF mechanically interchangeable?

A: Yes. Both components share identical connector type, position count (60), pitch spacing (0.079" / 2.00mm), row/column configuration (5 rows × 12 columns), mounting type (through hole), and termination method (solder). Physical dimensions and PCB footprints are equivalent.

Q: What is the difference between these two part numbers?

A: The 55444-101LF is the active production variant of the obsolete 55444-101. The primary differences are product status (active vs. obsolete) and RoHS compliance status (compliant vs. non-compliant). All functional and mechanical parameters remain identical.

Q: Can the 55444-101LF be used in legacy systems designed for the 55444-101?

A: Yes. The 55444-101LF maintains full compatibility with systems originally specified for the 55444-101 due to identical electrical and mechanical characteristics.

Q: What packaging is available for the 55444-101LF?

A: The 55444-101LF is supplied in tube packaging. The original 55444-101 packaging specification was not provided in the technical data.

Q: Are there any compliance considerations when substituting the 55444-101 with the 55444-101LF?

A: The 55444-101LF achieves RoHS compliance, which may be required for new designs or systems subject to current regulatory standards. Both components maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.
