50645-1240EB Equivalent & Substitute Parts

Part Overview

The 50645-1240EB is a 240-position high-density backplane connector receptacle manufactured by Amphenol ICC (FCI). This component features female sockets in a through-hole, right-angle configuration with press-fit termination and gold-plated contacts. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring this connector type.

Substitute Part Grouping Explanation

Substitution of the 50645-1240EB is determined by strict equivalence across the following electrical and mechanical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count and arrangement (240 positions, 3 rows × 80 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Press-Fit)
• Contact material and finish (Gold plating)
• Physical color and flammability rating (Black, UL94 V-0)

The 50645-1240EBLF meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and RoHS compliance, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 50645-1240EBLF is the direct substitute for the 50645-1240EB. Selection of the substitute part is justified on the following grounds:

• All electrical and mechanical parameters are identical, ensuring pin-for-pin and form-factor compatibility
• The substitute part maintains active product status, ensuring continued availability and supply chain reliability
• The substitute part is RoHS compliant, meeting current environmental and regulatory requirements
• Both parts share identical UL94 V-0 flammability certification and moisture sensitivity classification
• Packaging difference (Tube for the substitute) does not affect functional performance or PCB integration

For applications requiring the 50645-1240EB, the 50645-1240EBLF provides equivalent electrical and mechanical performance with improved compliance and availability status.

Frequently Asked Questions (FAQ)

Q: Are the 50645-1240EB and 50645-1240EBLF electrically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting configuration, and contact specifications. They are direct electrical equivalents.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), and packaging format (standard vs. tube). Electrical and mechanical specifications are identical.

Q: Can I use the 50645-1240EBLF as a replacement in existing designs using the 50645-1240EB?

A: Yes. The substitute part is mechanically and electrically compatible. No PCB redesign or connector interface modification is required.

Q: Does the packaging difference affect installation or performance?

A: No. Packaging format (Tube) affects only handling and storage logistics, not component performance or PCB integration.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part (50645-1240EBLF) is the active equivalent and is recommended for all new designs and ongoing production.

Q: Are both parts certified to the same flammability and moisture sensitivity standards?

A: Yes. Both parts carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification.
