Amphenol ICC 50004-1200H Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50004-1200H is a 200-position high-density backplane connector featuring female sockets in a through-hole, right-angle configuration. This receptacle connector is designed for PCB applications requiring high-density interconnection with a 0.100" (2.54mm) pitch across 4 rows and 50 columns.

The 50004-1200H carries an obsolete product status, which necessitates identification of active equivalent parts to ensure continued availability and supply chain continuity for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50004-1200H is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Total position count (200 positions)
• Connector style classification (High Density)
• Contact pitch (0.100" / 2.54mm)
• Physical configuration (4 rows, 50 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold plating)
• Series designation (HPC™)

Parts meeting all these criteria are functionally and mechanically interchangeable. Differences in product status and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1200HLF serves as the direct active equivalent to the obsolete 50004-1200H. Both parts are electrically and mechanically identical across all functional parameters.

Selection between these parts should be based on:

• Product Availability: The 50004-1200HLF maintains active production status with 821 units in stock, while the 50004-1200H is obsolete with limited remaining inventory (958 units).
• Regulatory Compliance: The 50004-1200HLF is RoHS Compliant, whereas the 50004-1200H is RoHS non-compliant. For applications subject to RoHS requirements, the 50004-1200HLF is the mandated choice.
• Supply Chain Continuity: New designs should specify the 50004-1200HLF to ensure long-term component availability and support.

Frequently Asked Questions (FAQ)

Q: Are the 50004-1200H and 50004-1200HLF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including pitch (0.100"), position count (200), configuration (4×50), mounting type (through-hole right-angle), and contact finish (gold). They are direct mechanical substitutes.

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

A: The primary differences are product status and RoHS compliance. The 50004-1200HLF is the active production variant with RoHS Compliant certification, while the 50004-1200H is obsolete and RoHS non-compliant. Electrical and mechanical performance are equivalent.

Q: Can I use the 50004-1200HLF as a replacement in existing designs using the 50004-1200H?

A: Yes. The 50004-1200HLF is a direct functional and mechanical equivalent. No design modifications are required for substitution.

Q: What does the "LF" suffix in 50004-1200HLF indicate?

A: The "LF" designation indicates Lead-Free termination and RoHS compliance, distinguishing this variant from the legacy 50004-1200H.

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

A: No. Both parts are specified with identical contact finish (gold, 30.0µin), pitch, and configuration. Electrical performance characteristics are equivalent.

Q: What is the Moisture Sensitivity Level for both parts?

A: Both the 50004-1200H and 50004-1200HLF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
