DF3A-10P-2DS Equivalent & Substitute Parts

Part Overview

The DF3A-10P-2DS is a rectangular connector header manufactured by Hirose Electric Co., Ltd., designed for through-hole, right-angle board-to-board or cable applications. This 10-position connector operates across a wide temperature range of -55°C to 105°C and is rated for 3A current capacity. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply constraints, lead time considerations, or specific application requirements that align with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3A-10P-2DS is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — must match exactly for mechanical compatibility
• Number of Positions: 10 — connector must accommodate the same pin count
• Number of Rows: 1 — single-row configuration required
• Mounting Type: Through Hole, Right Angle — board mounting method must be identical
• Connector Type: Header — functional classification must remain consistent
• Contact Type: Male Pin — gender must match the mating interface
• Shrouding Configuration: Shrouded design — protective housing required
• Material Flammability Rating: UL94 V-0 — compliance certification must be maintained
• RoHS Status: ROHS3 Compliant — regulatory requirement must be satisfied

The substitute part 1-292253-0 (TE Connectivity AMP Connectors, CT Series) meets these core substitution criteria. Variations in contact length, insulation height, contact shape, and shrouding wall count are permissible within the scope of equivalent functionality, provided the critical parameters listed above remain aligned.

Parameter Comparison

Engineering Selection Recommendations

Both the DF3A-10P-2DS and 1-292253-0 maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on:

Primary Criteria:

• Availability and lead time requirements
• PCB layout constraints related to insulation height and contact length variations
• Mechanical fit within the application enclosure, accounting for the 3-wall versus 4-wall shrouding difference

Secondary Considerations:

• The TE Connectivity 1-292253-0 features extended contact mating length (4.50mm vs. 3.10mm), which may provide enhanced engagement depth in certain mating scenarios
• The Hirose DF3A-10P-2DS maintains greater insulation height (5.00mm vs. 4.00mm), which may be advantageous in high-density PCB applications requiring additional creepage distance

Both parts satisfy the core electrical and mechanical requirements for 10-position, 2.00mm pitch header applications with equivalent current and temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can the DF3A-10P-2DS be directly replaced with the 1-292253-0?

A: Yes, within the constraints of PCB layout and mechanical fit. Both connectors share identical pitch (2.00mm), position count (10), row configuration (1), and mounting method (through-hole, right-angle). Variations in contact length and insulation height must be evaluated against specific application requirements.

Q: What is the significance of the shrouding wall count difference (4-wall vs. 3-wall)?

A: Shrouding wall count affects mechanical protection and keying. The 4-wall shrouding on the DF3A-10P-2DS provides additional lateral protection, while the 3-wall design on the 1-292253-0 reduces overall connector footprint. Both configurations maintain equivalent electrical performance and compliance ratings.

Q: Are there temperature or current rating differences between these parts?

A: The DF3A-10P-2DS is rated for 3A continuous current. The 1-292253-0 current rating varies by wire gauge, as it is designed for board-to-cable/wire applications. Operating temperature specifications for the 1-292253-0 were not provided in the technical data. Verify temperature requirements against application specifications before substitution.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the DF3A-10P-2DS and 1-292253-0 are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification. ECCN and HTSUS codes are identical for both parts.

Q: What factors should determine which part to select?

A: Selection should prioritize supply availability, lead time, PCB layout compatibility (considering the 0.87mm insulation height difference and 1.40mm contact mating length difference), and mechanical fit within the application enclosure. Both parts are functionally equivalent for standard 10-position, 2.00mm pitch header applications.
