DF1-6P-2.5DSA(05) Equivalent & Substitute Parts

Part Overview

The DF1-6P-2.5DSA(05) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This vertical 6-position connector operates at 2.5mm pitch with a 3A current rating and 250V voltage rating. The part is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1-6P-2.5DSA(05) is determined by the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.098" (2.50mm)
• Number of Positions: 6
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Voltage Rating: 250V
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part DF1B-6P-2.5DSA(01) meets all critical substitution criteria. Variations in secondary parameters such as shrouding design, fastening mechanism, contact finish, and insulation height do not prevent functional substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-6P-2.5DSA(01) is a qualified substitute for the DF1-6P-2.5DSA(05). Both parts maintain identical electrical specifications (250V voltage rating, 2.5mm pitch, 6-position configuration) and comply with ROHS3 and UL94 V-0 flammability requirements. The DF1B variant offers the advantage of Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

Design considerations include the DF1B's enhanced shrouding (4-wall versus 1-wall) and gold contact finish, which provide improved mechanical protection and contact reliability. The operating temperature range of the DF1B (-35°C ~ 85°C) exceeds that of the DF1-6P-2.5DSA(05) (-30°C ~ 85°C), offering broader environmental compatibility. The push-pull fastening mechanism of the DF1B differs from the friction lock design of the original part; this change requires verification of mating connector compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the DF1B-6P-2.5DSA(01) be used as a direct replacement for the DF1-6P-2.5DSA(05)?

A: Yes, the DF1B-6P-2.5DSA(01) meets all critical electrical and mechanical substitution criteria. Both parts share identical pitch (2.5mm), position count (6), voltage rating (250V), and flammability compliance (UL94 V-0). Mating connector compatibility must be confirmed, as the fastening mechanism differs between the two parts.

Q: What are the key differences between these two connectors?

A: Primary differences include shrouding design (1-wall versus 4-wall), fastening type (friction lock versus push-pull), contact finish (tin versus gold), and insulation height (7.50mm versus 9.50mm). The DF1B also provides a wider operating temperature range (-35°C to 85°C versus -30°C to 85°C).

Q: Why is the DF1-6P-2.5DSA(05) marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part. The DF1B-6P-2.5DSA(01) is the recommended active alternative within the Hirose DF1 series family.

Q: Are both parts RoHS compliant?

A: Yes, both the DF1-6P-2.5DSA(05) and DF1B-6P-2.5DSA(01) are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the impact of the different contact finishes?

A: The DF1-6P-2.5DSA(05) uses tin contact finish, while the DF1B-6P-2.5DSA(01) uses gold. Gold finish provides superior corrosion resistance and contact reliability, particularly in environments with higher humidity or corrosive atmospheres.

Q: Does the 4-wall shrouding of the DF1B affect compatibility?

A: The enhanced 4-wall shrouding of the DF1B provides improved mechanical protection and keying slot functionality. This design change requires confirmation that the mating connector or cable assembly is compatible with the DF1B shrouding geometry.
