DF1E-4P-2.5DS(01) Equivalent & Substitute Parts

Part Overview

The DF1E-4P-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 4-position connector operates at 3A current rating with a 0.098" (2.50mm) pitch and features shrouded design with gold-plated mating contacts. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1E-4P-2.5DS(01) is determined by the following critical parameters:

• Connector Type & Style: Header, board-to-cable/wire configuration
• Contact Configuration: Male pin, 4 positions, single row
• Pitch Specification: 0.098" (2.50mm) mating pitch
• Mounting Method: Through hole, right-angle orientation
• Shrouding Design: Shrouded - 4 wall construction
• Electrical Rating: 3A current capacity
• Termination Method: Solder-compatible termination
• Environmental Compliance: UL94 V-0 flammability rating

Two substitute parts meet these criteria: DF1E-4P-2.5DS(36) from Hirose Electric Co Ltd and S04B-XASK-1 from JST Sales America Inc. Both maintain the core mechanical and electrical parameters required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

DF1E-4P-2.5DS(36) is the primary substitute option. This part maintains identical specifications to the original DF1E-4P-2.5DS(01) while offering active product status from the same manufacturer. The part is RoHS compliant and carries the same series designation, ensuring design continuity. Packaging is available in bulk format.

S04B-XASK-1 serves as a cross-manufacturer alternative from JST Sales America Inc. This part satisfies all core mechanical and electrical requirements with identical pitch, position count, mounting configuration, and current rating. The operating temperature range is -25°C ~ 85°C, which covers the upper operational boundary of the original part. The connector features a locking ramp fastening mechanism and glass-filled nylon insulation. Contact finish differs (tin versus gold), and contact material is copper alloy rather than brass. This part is RoHS compliant and REACH unaffected.

Both substitute parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating, maintaining compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can DF1E-4P-2.5DS(36) be used as a direct replacement for DF1E-4P-2.5DS(01)?

A: Yes. Both parts share identical electrical and mechanical specifications including pitch, position count, current rating, operating temperature range, and mounting configuration. The primary difference is product status: DF1E-4P-2.5DS(36) is active while the original is obsolete.

Q: What are the key differences between the Hirose DF1E-4P-2.5DS(36) and JST S04B-XASK-1?

A: Both parts maintain the same 4-position, 2.50mm pitch header configuration with 3A current rating and through-hole right-angle mounting. Differences include: contact finish (gold versus tin), contact material (brass versus copper alloy), insulation material composition (standard nylon versus glass-filled nylon 6/6), fastening mechanism (latch holder versus locking ramp), and minimum operating temperature (-35°C versus -25°C).

Q: Are there packaging considerations when selecting a substitute?

A: DF1E-4P-2.5DS(36) is available in bulk packaging. S04B-XASK-1 is also available in bulk packaging. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating special storage requirements.

Q: Does the contact finish difference affect compatibility?

A: Contact finish (gold on Hirose parts versus tin on JST part) affects mating surface characteristics but does not prevent mechanical or electrical compatibility. Both finishes are suitable for solder termination and standard PCB applications.

Q: What is the operating temperature difference between substitutes?

A: The original DF1E-4P-2.5DS(01) and DF1E-4P-2.5DS(36) operate from -35°C to 85°C. The JST S04B-XASK-1 operates from -25°C to 85°C. For applications requiring operation below -25°C, the Hirose alternatives are required.
