Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-20P-2.5DSA is determined by the following critical parameters:

• Connector type (Header)
• Number of positions (20)
• Pitch specification (0.098" / 2.50mm)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Voltage rating (250V)
• Operating temperature range (-35°C ~ 85°C)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

The substitute part DF1BZ-20P-2.5DSA maintains identical specifications across all critical parameters, ensuring mechanical and electrical compatibility with applications designed for the original DF1B-20P-2.5DSA connector.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-20P-2.5DSA is a direct functional equivalent to the obsolete DF1B-20P-2.5DSA. Both connectors share identical mechanical and electrical specifications across all critical parameters including connector geometry, contact configuration, voltage rating, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The DF1BZ-20P-2.5DSA maintains active production status with Hirose Electric Co Ltd and carries RoHS compliance certification, whereas the original DF1B-20P-2.5DSA is obsolete and RoHS non-compliant. For new designs or ongoing component procurement, the DF1BZ-20P-2.5DSA is the appropriate selection.
