Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50645-1150EB is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Number of positions (150)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (3 rows × 50 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Press-Fit)
• Contact finish and material specifications (Gold, UL94 V-0)

The primary substitute identified is the 50645-1150EBLF, which maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance. Both parts share the same base product number (50645) and series designation (HPC™), confirming functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 50645-1150EBLF is the direct functional equivalent of the 50645-1150EB. Both connectors are electrically and mechanically identical across all specified parameters. The primary distinction lies in product lifecycle status and regulatory compliance:

The 50645-1150EB is classified as obsolete, indicating discontinued manufacturing and limited availability. The 50645-1150EBLF maintains active product status with current manufacturing support and improved regulatory alignment through RoHS compliance certification.

For new designs and production applications, the 50645-1150EBLF is the appropriate selection. For legacy system maintenance where the original 50645-1150EB is specified, the 50645-1150EBLF provides direct substitution without design modification or PCB rework.
