DF1E-2P-2.5DS(01) Equivalent & Substitute Parts

Part Overview

The DF1E-2P-2.5DS(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 2-position connector operates at 3A current rating with a 2.5mm pitch and features gold-plated brass contacts with polyamide insulation. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

The DF1E-2P-2.5DS(01) has one direct equivalent substitute: DF1E-2P-2.5DS(36). Both parts share identical electrical and mechanical specifications that define substitution compatibility:

• Same series designation (DF1E)
• Identical connector configuration (2-position header, right-angle, through-hole)
• Matching pitch specification (2.50mm)
• Identical contact type, material, and finish (male pin, brass, gold-plated)
• Same current rating (3A) and operating temperature range (-35°C ~ 85°C)
• Identical shrouding design (4-wall shrouded)
• Same insulation material and flammability rating (Polyamide/Nylon, UL94 V-0)

The primary distinction between these parts is product status and packaging configuration, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DF1E-2P-2.5DS(36) is the direct functional equivalent for the obsolete DF1E-2P-2.5DS(01). Selection of the substitute part is based on the following factors:

• Both parts maintain identical electrical and mechanical specifications, ensuring direct pin-for-pin and form-factor compatibility
• The DF1E-2P-2.5DS(36) carries active product status, providing ongoing availability and manufacturing support
• The substitute part holds ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Both parts share identical UL94 V-0 flammability certification and MSL rating
• Bulk packaging of the substitute part supports standard procurement workflows

Frequently Asked Questions (FAQ)

Q: Can DF1E-2P-2.5DS(36) be used as a direct replacement for DF1E-2P-2.5DS(01)?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector configuration, pitch, contact specifications, current rating, and operating temperature range. The primary difference is product status and packaging format.

Q: What is the significance of the part number suffix (01 vs 36)?

A: The suffix designates packaging and distribution configuration. The (01) variant is obsolete, while the (36) variant is active with bulk packaging. The core connector specifications remain unchanged.

Q: Are there any compliance differences between these parts?

A: The DF1E-2P-2.5DS(36) explicitly declares ROHS3 compliance and REACH unaffected status. Both parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (header), contact type (male pin), number of positions (2), pitch (2.50mm), mounting style (through-hole right-angle), shrouding design (4-wall), contact material and finish (brass with gold plating), insulation material (polyamide/nylon), current rating (3A), and operating temperature range (-35°C ~ 85°C).

Q: Is the packaging difference between these parts significant?

A: Packaging format does not affect electrical or mechanical function. The DF1E-2P-2.5DS(36) bulk packaging aligns with standard procurement practices for active components.
