Amphenol ICC 50003-1120H Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1120H is a 120-position high-density backplane connector receptacle with female sockets, designed for through-hole, right-angle PCB mounting. This connector features a 0.100" (2.54mm) pitch configuration across 4 rows and 30 columns, with gold-plated contacts and integral mating guide.

The 50003-1120H carries an obsolete product status. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new production builds where this connector specification remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1120H is determined by strict equivalence across the following parameters:

• Connector type (Receptacle, Female Sockets)
• Position count (120 positions)
• Connector style (High Density)
• Pitch specification (0.100" / 2.54mm)
• Row and column configuration (4 × 30)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Series designation (HPC™)

The substitute part 50003-1120HLF meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1120HLF is the direct substitute for the obsolete 50003-1120H. Both parts share identical electrical and mechanical specifications, ensuring form, fit, and function compatibility.

The primary distinction is product lifecycle status: the 50003-1120H is obsolete, while the 50003-1120HLF is active and currently manufactured. Additionally, the 50003-1120HLF achieves RoHS compliance, whereas the 50003-1120H does not.

For new designs or ongoing production requiring this 120-position high-density backplane connector specification, the 50003-1120HLF is the appropriate selection. For legacy system maintenance where the original part number must be retained, the 50003-1120H remains available in existing inventory (961 pieces).

Frequently Asked Questions (FAQ)

Q: Are the 50003-1120H and 50003-1120HLF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), position count (120), pitch (0.100"), and row/column configuration (4 × 30). They are mechanically interchangeable.

Q: Are the 50003-1120H and 50003-1120HLF electrically interchangeable?

A: Yes. Both connectors feature identical contact finish (gold, 30.0µin), termination method (solder), and series designation (HPC™). They are electrically interchangeable.

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