50003-1216E Equivalent & Substitute Parts

Part Overview

The 50003-1216E is a 216-position high-density backplane connector receptacle manufactured by Amphenol ICC (FCI). This through-hole, right-angle mounted connector features female sockets with gold-plated contacts and is part of the HPC™ series. The part is currently obsolete, making identification of compatible substitutes essential for legacy system maintenance and board redesigns. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct PCB compatibility without layout modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1216E is determined by strict equivalence across the following parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Total position count (216 positions)
• High-density connector style classification
• Contact pitch (0.100" / 2.54mm)
• Row and column configuration (4 × 54)
• Mounting orientation (Through Hole, Right Angle)
• Solder termination method
• Contact material and finish specification (Gold, 30.0µin)
• Presence of mating guide feature
• Series designation (HPC™)

The 50003-1216ELF qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status and regulatory compliance, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1216ELF is the direct functional equivalent of the 50003-1216E. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, and contact finish. The 50003-1216ELF is the preferred selection for new designs and component replenishment due to its active product status and RoHS compliance. For legacy systems requiring the original 50003-1216E, the 50003-1216ELF provides complete interchangeability without PCB redesign or layout modification. The RoHS compliance of the 50003-1216ELF aligns with current regulatory requirements for electronic components in most markets.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1216ELF be used as a direct replacement for the 50003-1216E on existing PCBs?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including connector type, position count, pitch, mounting type, and contact specifications. No PCB modifications are required.

Q: What is the difference between the 50003-1216E and 50003-1216ELF?

A: The parts are functionally equivalent. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. compliant). All connector specifications remain unchanged.

Q: Are there any compatibility concerns when substituting the 50003-1216ELF for the 50003-1216E?

A: No compatibility concerns exist. The parts maintain identical mating interface geometry, contact pitch, and termination method. Mating connectors designed for the 50003-1216E will function identically with the 50003-1216ELF.

Q: Does the RoHS compliance of the 50003-1216ELF affect its electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics.

Q: What is the availability difference between these parts?

A: The 50003-1216E is obsolete with limited remaining inventory (977 pcs). The 50003-1216ELF is active production with current availability (832 pcs). For ongoing supply requirements, the 50003-1216ELF is the recommended selection.
