Amphenol ICC 50003-1120F High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1120F is a 120-position high-density backplane connector featuring female sockets in a through-hole, right-angle configuration. This receptacle connector is part of the HPC™ series and is designed for PCB mounting applications requiring high-density interconnection in a 4-row by 30-column layout with 0.100" (2.54mm) pitch spacing.

The 50003-1120F is currently classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

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

• Connector Type & Style: Receptacle with female sockets in high-density configuration
• Position Count & Layout: Exactly 120 positions arranged in 4 rows × 30 columns
• Pitch Spacing: 0.100" (2.54mm) center-to-center contact spacing
• Mounting Configuration: Through-hole, right-angle orientation for PCB mounting
• Termination Method: Solder termination for permanent board attachment
• Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
• Series Designation: HPC™ series compatibility

The substitute part identified below maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence and PCB-level compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1120FLF serves as the direct active-production equivalent to the obsolete 50003-1120F. Both parts share identical electrical and mechanical specifications, ensuring complete functional interchangeability at the PCB level.

The primary distinction between these parts is product lifecycle status and regulatory compliance:

• 50003-1120F: Obsolete status with RoHS non-compliant certification. Suitable for legacy system maintenance where existing inventory is available and regulatory compliance is not a requirement.

• 50003-1120FLF: Active production status with RoHS Compliant certification. Recommended for new designs, ongoing production, and applications subject to RoHS regulatory requirements. Higher inventory availability (1018 units) supports sustained supply chain continuity.

For applications requiring RoHS compliance or long-term component availability, the 50003-1120FLF is the appropriate selection. For legacy system support where RoHS compliance is not mandated, either part may be used interchangeably based on inventory and regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1120FLF be used as a direct replacement for the 50003-1120F?

A: Yes. Both connectors are electrically and mechanically identical across all specified parameters, including position count, pitch spacing, mounting configuration, and contact finish. PCB-level substitution requires no design modification.

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

A: The primary differences are product status and RoHS compliance. The 50003-1120F is obsolete and RoHS non-compliant. The 50003-1120FLF is in active production and RoHS Compliant. All functional specifications are identical.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts maintain identical contact finish, pitch, and electrical characteristics.

Q: Are there any PCB layout or footprint changes between these parts?

A: No. Both connectors share identical mounting type (through-hole, right-angle), position layout (4 rows × 30 columns), and pitch spacing (0.100"). Existing PCB designs require no modification.

Q: Which part should be selected for new designs?

A: The 50003-1120FLF is recommended for new designs due to active production status, RoHS compliance, and superior inventory availability. The 50003-1120F should be reserved for legacy system maintenance only.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
