DF1B-9P-2.5DS(01) Equivalent & Substitute Parts

Part Overview

The DF1B-9P-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 9-position connector operates at 250V with a 0.098" (2.50mm) pitch and features shrouded 4-wall construction with push-pull fastening. The part is currently active in production with 947 units in stock. Equivalent parts are identified when design requirements permit substitution based on matching electrical and mechanical parameters within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-9P-2.5DS(01) is determined by the following critical parameters:

• Connector Type & Contact Type: Must be Header with Male Pin configuration
• Position Count & Pitch: Must maintain 9 positions at 0.098" (2.50mm) mating pitch
• Mounting & Orientation: Must support through-hole, right-angle mounting
• Shrouding Configuration: Must provide shrouded 4-wall construction
• Electrical Ratings: Must meet or exceed 250V voltage rating
• Compliance: Must maintain UL94 V-0 flammability rating and RoHS compliance

The Molex 0534260910 (Mini-Lock 53426 series) satisfies these substitution criteria across all critical parameters, enabling direct functional equivalence in applications requiring 9-position, 2.5mm-pitch right-angle headers with shrouded construction.

Parameter Comparison

Engineering Selection Recommendations

Both the DF1B-9P-2.5DS(01) and 0534260910 are active production parts with equivalent functional specifications for 9-position, 2.5mm-pitch right-angle header applications. Selection between these parts should be based on:

Hirose DF1B-9P-2.5DS(01): Recommended when push-pull fastening mechanism is specified, square contact geometry is required, or when Hirose series continuity is mandated in the design. RoHS Compliant status applies.

Molex 0534260910: Recommended when locking ramp fastening is preferred, extended operating temperature range (-40°C ~ 105°C) is required, or when Molex Mini-Lock series integration is specified. ROHS3 Compliant status applies. Higher inventory availability (3009 units) supports supply chain continuity.

Both parts meet UL94 V-0 flammability requirements, 250V voltage rating, and MSL 1 moisture sensitivity classification. Contact material and finish differences (Hirose: brass with gold; Molex: phosphor bronze with tin) do not affect functional substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0534260910 directly replace the Hirose DF1B-9P-2.5DS(01) in existing designs?

A: Yes, for applications where the design specifies 9-position, 2.5mm-pitch right-angle headers with shrouded 4-wall construction and 250V rating. The fastening mechanism differs (push-pull vs. locking ramp), so verify connector mating compatibility with the corresponding receptacle before implementation.

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

A: Primary differences include fastening type (push-pull vs. locking ramp), contact material (brass vs. phosphor bronze), contact finish (gold vs. tin), insulation material composition, and operating temperature range. Electrical and mechanical pitch specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. The Hirose DF1B-9P-2.5DS(01) is RoHS Compliant, and the Molex 0534260910 is ROHS3 Compliant. Both meet current RoHS requirements.

Q: What is the packaging difference?

A: The Hirose part does not specify packaging type in the provided data. The Molex 0534260910 is supplied in Tray packaging.

Q: Which part has better availability?

A: The Molex 0534260910 has higher current inventory (3009 units) compared to the Hirose DF1B-9P-2.5DS(01) (947 units).

Q: Can I use these connectors in high-temperature applications?

A: The Molex 0534260910 supports extended operating temperature range (-40°C ~ 105°C), making it suitable for higher-temperature environments. The Hirose DF1B-9P-2.5DS(01) operates within -35°C ~ 85°C range.
