Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1B-3P-2.5DSA is determined by strict equivalence across the following critical parameters:

• Connector pitch: 0.098" (2.50mm)
• Number of positions: 3
• Mounting configuration: Through hole
• Shrouding design: Shrouded - 4 wall
• Contact type: Male pin
• Fastening mechanism: Push-pull
• Voltage rating: 250V
• Operating temperature range: -35°C ~ 85°C
• Insulation material: Polyamide (PA), Nylon
• Contact material: Brass with tin finish

The DF1BZ-3P-2.5DSA meets all these criteria and is classified as a direct substitute within the DF1B series.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-3P-2.5DSA is the direct substitute for the obsolete DF1B-3P-2.5DSA. Both components share identical mechanical and electrical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the DF1BZ-3P-2.5DSA is currently in active production and meets ROHS3 compliance requirements, whereas the original part is obsolete and RoHS non-compliant. For new designs or ongoing procurement, the DF1BZ-3P-2.5DSA is the appropriate selection. Both parts are manufactured by Hirose Electric Co Ltd within the same DF1B series and maintain full functional and dimensional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DF1BZ-3P-2.5DSA be used as a direct replacement for the DF1B-3P-2.5DSA?

A: Yes. The DF1BZ-3P-2.5DSA is a direct substitute. All mechanical dimensions, electrical ratings, contact configurations, and mounting specifications are identical between the two parts.

Q: What is the primary reason to transition from DF1B-3P-2.5DSA to DF1BZ-3P-2.5DSA?

A: The DF1B-3P-2.5DSA is obsolete and no longer in production. The DF1BZ-3P-2.5DSA is the active equivalent from Hirose Electric Co Ltd and is available in production quantities.

Q: Are there any compliance differences between these parts?

A: Yes. The DF1BZ-3P-2.5DSA is ROHS3 compliant, while the DF1B-3P-2.5DSA is RoHS non-compliant. For applications requiring RoHS compliance, the DF1BZ-3P-2.5DSA is the required selection.

Q: Will the DF1BZ-3P-2.5DSA fit existing PCB designs intended for the DF1B-3P-2.5DSA?

A: Yes. Both parts have identical through-hole mounting footprints, shrouding dimensions, and contact spacing. No PCB redesign is required.

Q: What is the packaging difference between these parts?

A: The DF1B-3P-2.5DSA packaging is listed as unspecified. The DF1BZ-3P-2.5DSA is supplied in bulk packaging.

Q: Are the contact finishes identical?

A: Both parts feature tin contact finish on the mating surface. The DF1BZ-3P-2.5DSA specifies additional detail: contact finish thickness of 39.4µin (1.00µm) on the mating surface and tin finish on the post.
