Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1240E 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 240 positions in 4×60 arrangement
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained
• Mounting & Termination: Through-hole, right-angle, solder termination
• Contact Specifications: Gold finish at 30.0µin thickness
• Series Compatibility: HPC™ series designation

The primary distinction between the main part and its substitute is product status and compliance certification. The 50003-1240E is obsolete and RoHS non-compliant, while active alternatives maintain current manufacturing status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1240ELF serves as the direct active equivalent to the obsolete 50003-1240E. Both parts maintain identical electrical and mechanical specifications across all critical connector parameters. The substitution is based on:

Product Status: The 50003-1240ELF is actively manufactured, whereas the 50003-1240E is obsolete. For new designs or system refreshes, the active part number ensures long-term supply chain viability.

Compliance Certification: The 50003-1240ELF is RoHS compliant, meeting current regulatory requirements for electronic component manufacturing and distribution. The 50003-1240E does not meet RoHS compliance standards.

Functional Equivalence: All connector parameters—position count, pitch, mounting configuration, contact finish, and mating features—are identical between both parts, ensuring direct mechanical and electrical interchangeability in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1240ELF be used as a direct replacement for the 50003-1240E in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters. The 50003-1240ELF is the active equivalent and can be substituted without PCB redesign or connector interface modifications.

Q: What is the significance of the "LF" suffix in the 50003-1240ELF part number?

A: The "LF" designation indicates lead-free and RoHS compliance. This reflects the manufacturing process and material composition changes required to meet current environmental and regulatory standards.

Q: Are there any differences in mating compatibility between these two part numbers?

A: No. Both receptacles feature identical 240-position configurations, 0.100" pitch, and mating guide features. They are fully compatible with the same plug connectors and mating interfaces.

Q: Why should I transition from the 50003-1240E to the 50003-1240ELF?

A: The 50003-1240E is obsolete and non-compliant with RoHS regulations. The 50003-1240ELF is actively manufactured, ensuring supply chain continuity, regulatory compliance, and support for current and future applications.

Q: Are the through-hole solder termination specifications identical?

A: Yes. Both parts use identical solder termination methods and through-hole mounting configurations, requiring no changes to PCB layout or assembly processes.
