Amphenol ICC 50004-1104E High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50004-1104E is a 104-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 26-column layout with 0.100" (2.54mm) pitch spacing.

The 50004-1104E carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing system support and new design implementations. Active equivalent models are available that maintain full electrical and mechanical compatibility while offering current manufacturing support and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 50004-1104E is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets in high-density configuration (HDC, HDI, HPC)
• Position Count & Layout: Exactly 104 positions arranged in 4 rows × 26 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 Specifications: Gold finish at 30.0µin (0.76µm) thickness with mating guide feature
• Base Series: HPC™ series compatibility

The substitute part 50004-1104ELF maintains complete electrical and mechanical equivalence across all specified parameters. The primary distinction lies in product status and regulatory compliance, with the substitute offering active manufacturing status and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1104ELF is the direct functional equivalent for the obsolete 50004-1104E. Selection between these parts should be based on the following criteria:

For New Designs and Current Production: The 50004-1104ELF is the appropriate choice. This part carries active product status, ensuring ongoing manufacturing availability and technical support from Amphenol ICC. The RoHS compliance certification aligns with current environmental regulations and procurement standards applicable to most industries.

For Legacy System Support: The 50004-1104E remains available in current inventory (932 units) for applications where existing designs are locked to the original part number or where non-compliant components are explicitly required by specification.

Compliance Considerations: Organizations subject to RoHS directives, conflict minerals regulations, or similar environmental compliance frameworks should transition to the 50004-1104ELF. The substitute part maintains identical electrical and mechanical specifications while meeting these regulatory requirements.

Both parts share identical MSL ratings, ECCN classifications, and tariff codes, indicating no supply chain or logistics complications associated with substitution.

Frequently Asked Questions (FAQ)

Q: Are the 50004-1104E and 50004-1104ELF mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch spacing (0.100"), position count (104), row/column layout (4×26), mounting type (through-hole right-angle), and contact specifications (gold finish at 30.0µin thickness). Direct PCB footprint compatibility is confirmed.

Q: What is the primary reason for substituting the 50004-1104E?

A: The 50004-1104E carries obsolete product status, indicating discontinued manufacturing. The 50004-1104ELF provides the same electrical and mechanical functionality with active manufacturing support and RoHS compliance certification.

Q: Will the 50004-1104ELF work in existing designs using the 50004-1104E?

A: Yes. The substitute part maintains complete compatibility across all specified electrical and mechanical parameters. No design modifications are required for PCB layouts, mating connectors, or signal integrity specifications.

Q: What is the difference between the part numbers 50004-1104E and 50004-1104ELF?

A: The suffix "LF" in the 50004-1104ELF designation indicates RoHS compliance and lead-free manufacturing processes. The core connector design, position count, pitch, and contact specifications remain identical.

Q: Are there any inventory or lead time considerations?

A: The 50004-1104E has 932 units in current stock but carries obsolete status. The 50004-1104ELF has 744 units available with active product status, ensuring continued availability and shorter lead times for future orders.

Q: Do both parts share the same MSL rating and handling requirements?

A: Yes. Both the 50004-1104E and 50004-1104ELF carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Standard handling procedures for through-hole connectors apply equally to both parts.

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

A: No. Both parts are specified with identical contact finish (gold at 30.0µin thickness), mating guide features, and base product series (HPC™). Electrical performance characteristics are equivalent.
