DF3A-4P-2DS(10) Equivalent & Substitute Parts

Part Overview

The DF3A-4P-2DS(10) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable connections with a 4-position, single-row configuration at 2.00mm pitch. This part is classified as obsolete and has been superseded in active production. Due to its obsolete status and limited availability in legacy configurations, identifying equivalent substitute parts is essential for ongoing system support, repairs, and new designs requiring compatible interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3A-4P-2DS(10) is determined by strict alignment of the following electrical and mechanical parameters:

• Connector pitch: 0.079" (2.00mm) mating pitch
• Position count: 4-position configuration
• Row configuration: Single row
• Connector type: Header with male pin contacts
• Mounting method: Through hole, right angle orientation
• Fastening mechanism: Push-pull engagement
• Current capacity: 3A minimum rating
• Temperature range: -55°C to 105°C operational limits
• Contact material and finish: Brass with tin plating
• Insulation material: Polyamide (PA), Nylon
• Compliance standards: RoHS3 compliance, UL94 V-0 flammability rating

The substitute part DF3A-4P-2DS meets all these criteria and represents the active production equivalent within the DF3 series family.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-4P-2DS serves as the direct active production substitute for the obsolete DF3A-4P-2DS(10). Both parts share identical electrical and mechanical specifications within the DF3 series family, ensuring functional compatibility in applications requiring 4-position, 2.00mm pitch rectangular connectors with through-hole, right-angle mounting.

The active substitute maintains full compliance with RoHS3 regulations and REACH requirements, supporting modern manufacturing and environmental standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Selection of the DF3A-4P-2DS is appropriate for new designs, system repairs, and legacy product support where the original DF3A-4P-2DS(10) configuration is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the DF3A-4P-2DS directly replace the DF3A-4P-2DS(10)?

A: Yes. Both parts are manufactured by Hirose Electric Co Ltd within the DF3 series and share identical mating pitch (2.00mm), position count (4), connector type (header), contact type (male pin), mounting method (through hole, right angle), and fastening mechanism (push-pull). The active substitute maintains the same electrical and thermal specifications.

Q: What is the significance of the "(10)" designation in the obsolete part number?

A: The "(10)" suffix in DF3A-4P-2DS(10) represents a specific packaging or configuration variant. The active substitute DF3A-4P-2DS is supplied in bulk packaging and represents the current production standard for this connector configuration.

Q: Are there any compliance differences between the obsolete and active parts?

A: Both parts are RoHS3 compliant and carry MSL 1 (Unlimited) ratings. The active substitute includes documented REACH Unaffected status and EAR99 export classification, providing additional regulatory clarity for modern supply chain requirements.

Q: What applications are compatible with this connector?

A: The DF3A-4P-2DS is designed for board-to-board or cable interconnection applications requiring 4-position connections at 2.00mm pitch with push-pull engagement. The 3A current rating and -55°C to 105°C operating temperature range support industrial and consumer electronics applications.

Q: Is the contact finish specification critical for substitution?

A: Yes. Both the obsolete and active parts feature tin-plated brass contacts. Tin plating ensures reliable electrical contact and corrosion resistance. Contact finish must remain consistent for proper mating performance and electrical continuity.

Q: What is the moisture sensitivity level, and does it affect storage?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These connectors do not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and logistics.
