DF1B-5P-2.5DSA Equivalent & Substitute Parts

Part Overview

The DF1B-5P-2.5DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This connector features 5 positions at 2.5mm pitch with shrouded 4-wall construction and push-pull fastening. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1B-5P-2.5DSA is determined by strict equivalence across the following parameters: connector type (header), contact type (male pin), number of positions (5), mating pitch (2.5mm), mounting method (through hole), shrouding configuration (4-wall), fastening mechanism (push-pull), voltage rating (250V), operating temperature range (-35°C to 85°C), and flammability classification (UL94 V-0). All identified substitutes maintain these core electrical and mechanical specifications. Variations in contact finish material and RoHS compliance status do not affect functional interchangeability in applications where the original part was specified.

Parameter Comparison

Engineering Selection Recommendations

Both DF1BZ-5P-2.5DSA and DF1B-5P-2.5DSA(01) are active product alternatives to the obsolete DF1B-5P-2.5DSA. Selection between these substitutes depends on regulatory and compliance requirements specific to the application.

The DF1BZ-5P-2.5DSA maintains tin contact finish and achieves ROHS3 compliance, providing a direct functional replacement with modern regulatory status.

The DF1B-5P-2.5DSA(01) features gold contact finish with ROHS3 compliance. Gold plating provides enhanced corrosion resistance and contact reliability in applications subject to environmental exposure or extended storage periods.

Both substitutes are available in active inventory with equivalent electrical and mechanical specifications to the original part.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-5P-2.5DSA and DF1B-5P-2.5DSA(01) be used interchangeably with DF1B-5P-2.5DSA?

A: Both parts are electrically and mechanically equivalent. They maintain identical connector type, position count, pitch, mounting configuration, voltage rating, and operating temperature range. The primary differences are contact finish material and RoHS compliance status, which do not affect functional interchangeability.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish affects corrosion resistance and long-term contact reliability. Tin finish is suitable for standard applications with controlled environmental conditions. Gold finish provides superior corrosion resistance and is specified for applications with extended storage, high humidity exposure, or demanding reliability requirements.

Q: Are all three parts compatible with the same mating connectors?

A: Yes. All three parts share identical mechanical dimensions, pitch, shrouding configuration, and fastening mechanism. They are compatible with the same mating receptacle connectors designed for the DF1B series at 2.5mm pitch.

Q: Why is the original DF1B-5P-2.5DSA listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. Active alternatives with equivalent specifications are available to support ongoing design and production requirements.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance addresses material composition and environmental impact but does not alter electrical performance. Both RoHS-compliant and non-compliant versions maintain identical electrical ratings and operating characteristics.
