DF1B-14DP-2.5DSA Equivalent & Substitute Parts

Part Overview

The DF1B-14DP-2.5DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting with 14 positions at 2.5mm pitch. This connector features a shrouded 4-wall design with push-pull fastening and solder termination for board-to-cable/wire applications. The main part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1B-14DP-2.5DSA is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and fastening mechanism (Header, Male Pin, Push-Pull)
• Position count and row configuration (14 positions, 2 rows)
• Pitch and row spacing (0.098" / 2.50mm)
• Mounting method and termination (Through Hole, Solder)
• Shrouding design (Shrouded - 4 Wall)
• Operating temperature range (-35°C ~ 85°C)
• Voltage rating (250V)
• Flammability rating (UL94 V-0)
• Insulation material (Polyamide/Nylon)

The substitute parts identified maintain full electrical and mechanical compatibility with the original specification while differing in product status, RoHS compliance, and contact finish specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-14DP-2.5DSA is classified as obsolete. Two active substitute parts are available:

DF1BZ-14DP-2.5DSA is the direct functional equivalent with identical electrical and mechanical specifications. This part is ROHS3 compliant and maintains the same tin contact finish as the original. The DF1BZ variant designation indicates an updated product line within the DF1B series.

DF1B-14DP-2.5DSA(01) is the manufacturer-recommended substitute, also ROHS3 compliant. The primary distinction is the gold contact finish on the mating surface (8.00µin / 0.203µm thickness) compared to the tin finish of the original part. Gold plating provides enhanced corrosion resistance and contact reliability in applications requiring extended service life or exposure to corrosive environments.

Both substitute parts maintain full compatibility with the original specification across all critical parameters: connector geometry, pitch, row configuration, mounting method, termination, fastening mechanism, operating temperature range, voltage rating, and flammability classification.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-14DP-2.5DSA be used as a direct replacement for DF1B-14DP-2.5DSA?

A: Yes. The DF1BZ-14DP-2.5DSA maintains identical electrical and mechanical specifications. The DF1BZ designation indicates an updated product line variant within the DF1B series. Both parts share the same 14-position, 2-row configuration at 2.5mm pitch, through-hole mounting, push-pull fastening, and tin contact finish.

Q: What is the difference between DF1BZ-14DP-2.5DSA and DF1B-14DP-2.5DSA(01)?

A: Both are active substitutes with identical connector geometry and electrical ratings. The primary difference is the contact finish: DF1BZ-14DP-2.5DSA uses tin plating, while DF1B-14DP-2.5DSA(01) uses gold plating (8.00µin thickness) on the mating contact surface. Gold plating offers superior corrosion resistance and contact durability.

Q: Are all three parts RoHS compliant?

A: The original DF1B-14DP-2.5DSA is RoHS non-compliant. Both substitute parts, DF1BZ-14DP-2.5DSA and DF1B-14DP-2.5DSA(01), are ROHS3 compliant.

Q: Do these connectors support the same mating cycles and fastening force?

A: Yes. All three parts feature identical push-pull fastening mechanisms and are rated for the same operating conditions within the -35°C to 85°C temperature range at 250V.

Q: What is the packaging difference between these parts?

A: The original DF1B-14DP-2.5DSA was supplied in unspecified packaging. Both substitute parts are supplied in bulk packaging.

Q: Are there any mechanical dimension differences between these parts?

A: No. All three parts share identical mechanical dimensions: contact length (mating 0.177", post 0.142"), overall contact length 0.417", insulation height 0.374", and mated stacking height 14mm.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. DF1BZ-14DP-2.5DSA is suitable for standard applications requiring RoHS3 compliance. DF1B-14DP-2.5DSA(01) is recommended for applications requiring enhanced contact reliability and corrosion resistance through gold plating.
