Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-16P-2.5DSA is determined by the following critical parameters:

• Connector Type & Series: Must be Header type from the DF1B series
• Position Count & Pitch: Must maintain 16 positions at 0.098" (2.50mm) mating pitch
• Contact Configuration: Male pin contacts with square shape
• Mounting & Termination: Through-hole mounting with solder termination
• Shrouding & Fastening: Shrouded 4-wall construction with push-pull fastening
• Electrical Ratings: 250V voltage rating and UL94 V-0 flammability compliance
• Environmental Range: Operating temperature -35°C ~ 85°C

The DF1BZ-16P-2.5DSA qualifies as a direct substitute, maintaining identical mechanical and electrical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-16P-2.5DSA is a direct functional equivalent to the DF1B-16P-2.5DSA. Both connectors share identical mechanical dimensions, electrical ratings, and performance specifications across all critical parameters. The primary distinction is product lifecycle status: the original DF1B-16P-2.5DSA is obsolete, while the DF1BZ-16P-2.5DSA maintains active production status.

The DF1BZ-16P-2.5DSA additionally provides RoHS compliance, whereas the original part is RoHS non-compliant. Both parts maintain UL94 V-0 flammability certification and identical operating temperature ranges. For new designs or component replenishment, the DF1BZ-16P-2.5DSA is the appropriate selection due to its active availability and regulatory compliance profile.
