Amphenol ICC 50003-1220F High Density Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1220F is a 220-position high-density backplane connector receptacle with female sockets, designed for through-hole, right-angle PCB mounting. This connector is part of the HPC™ series and features gold-plated contacts with a 0.100" (2.54mm) pitch arranged in a 4-row by 55-column configuration. The part is currently classified as obsolete, making identification of active equivalent models essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1220F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (220 positions)
• Connector style classification (High Density)
• Contact pitch (0.100" / 2.54mm)
• Row and column configuration (4 × 55)
• Mounting orientation and method (Through Hole, Right Angle)
• Termination method (Solder)
• Contact material and finish specification (Gold plating)
• Series designation (HPC™)

The substitute part 50003-1220FLF meets all these criteria and represents an active production equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1220FLF is the direct active production equivalent of the obsolete 50003-1220F. Both parts share identical electrical and mechanical specifications across all defined parameters. The primary distinction is product status: the 50003-1220F is obsolete, while the 50003-1220FLF maintains active manufacturing status.

The 50003-1220FLF additionally carries RoHS compliance certification, which may be required for applications subject to environmental regulations. Current inventory availability for the 50003-1220FLF (752 pieces) exceeds that of the obsolete part (683 pieces), supporting long-term supply chain continuity.

For new designs or production requiring 220-position high-density backplane receptacles with the specified configuration, the 50003-1220FLF is the appropriate selection. For legacy system maintenance where the original 50003-1220F is no longer available, the 50003-1220FLF provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1220F and 50003-1220FLF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), PCB footprint dimensions (4 rows × 55 columns at 0.100" pitch), and contact arrangement. They are direct mechanical substitutes.

Q: What is the significance of the "FLF" suffix in the part number?

A: The "FLF" suffix indicates the active production variant with RoHS compliance. The base part number 50003-1220F identifies the connector family and configuration; the suffix denotes manufacturing status and regulatory compliance level.

Q: Can the 50003-1220FLF be used in applications originally designed for the 50003-1220F?

A: Yes. The 50003-1220FLF meets or exceeds all electrical and mechanical specifications of the original part. RoHS compliance of the substitute part does not restrict its use in applications not requiring RoHS certification.

Q: What are the critical parameters for confirming connector compatibility?

A: Compatibility is determined by: connector type (receptacle vs. plug), gender (male vs. female), position count (220), pitch (0.100"), row/column configuration (4 × 55), mounting method (through-hole, right-angle), and contact finish (gold plating). All these parameters are identical between the two parts.

Q: Is the 50003-1220FLF suitable for new product designs?

A: Yes. The 50003-1220FLF is an active production part with current inventory availability and RoHS compliance, making it the appropriate choice for new designs requiring 220-position high-density backplane receptacles.
