Amphenol ICC 50003-1248E Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1248E is a 248-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 configuration across 4 rows and 62 columns.

The 50003-1248E is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and field service requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1248E is determined by the following critical parameters:

• Manufacturer & Series: Must be Amphenol ICC (FCI) HPC™ series to ensure mechanical and electrical compatibility
• Connector Type & Style: Must be receptacle with female sockets in high-density configuration
• Number of Positions: Must be 248 positions to match pin count requirements
• Pitch & Row/Column Configuration: Must maintain 0.100" (2.54mm) pitch with 4-row layout
• Mounting Type & Termination: Must be through-hole, right-angle with solder termination
• Contact Finish: Must be gold-plated to maintain electrical performance specifications

The substitute part 50003-1248ELF meets all critical mechanical and electrical parameters. However, it differs in column count (48 columns versus 62 columns in the original), which represents a geometric variation within the same connector family while maintaining the 248-position total through a different row-column arrangement.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1248ELF is the primary substitute for the obsolete 50003-1248E. Selection should be based on the following factors:

Product Status: The 50003-1248E is obsolete, while the 50003-1248ELF is active and currently in production. For new designs or ongoing production support, the 50003-1248ELF provides assured long-term availability.

Regulatory Compliance: The 50003-1248ELF is RoHS compliant, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies current environmental compliance standards.

Inventory Availability: The 50003-1248ELF has 691 units in stock, providing immediate availability for component procurement.

Geometric Consideration: The column count difference (48 versus 62) requires PCB layout verification to confirm that the connector footprint and mating interface are compatible with the existing design. This is the primary technical consideration for substitution feasibility.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1248ELF directly replace the 50003-1248E on existing PCBs?

A: Direct replacement depends on PCB layout compatibility. Both connectors maintain 248 positions with 0.100" pitch and 4-row configuration, but the column arrangement differs (48 versus 62 columns). The physical footprint and mounting hole pattern must be verified against the original PCB design before substitution.

Q: What is the significance of the column count difference?

A: The column count reflects the geometric arrangement of the 248 positions. The 50003-1248E uses a 4×62 arrangement, while the 50003-1248ELF uses a 4×48 arrangement. Both maintain the same total position count and pitch, but the connector body dimensions differ. PCB footprint compatibility must be confirmed.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, etc.) in the connector. The 50003-1248ELF's RoHS compliance status makes it suitable for applications subject to RoHS regulations, including EU markets and many OEM requirements. The original 50003-1248E does not meet these standards.

Q: Are the electrical specifications identical between these parts?

A: Both connectors share identical electrical specifications: 248 positions, 0.100" pitch, gold contact finish (30.0µin thickness), and solder termination. Electrical performance is equivalent when used within their respective design parameters.

Q: What should be verified before implementing the 50003-1248ELF as a substitute?

A: Verification should include: PCB footprint compatibility with the 4×48 column arrangement, mating connector compatibility, mechanical clearance for the right-angle mounting, and confirmation that the connector body dimensions do not conflict with adjacent components or enclosure constraints.
