DF3A-2P-2DS(18) Equivalent & Substitute Parts

Part Overview

The DF3A-2P-2DS(18) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable connections with a 2-position, single-row configuration. This part is classified as obsolete and is no longer in active production. Due to its obsolete status, sourcing original inventory becomes increasingly difficult. The DF3A-2P-2DS serves as the direct active equivalent, maintaining full compatibility with the original design specifications while offering reliable availability from current manufacturing stock.

Key Parameters

Substitute Part Grouping Explanation

The DF3A-2P-2DS is the direct substitute for the obsolete DF3A-2P-2DS(18). Substitution is based on the following critical parameters that must remain identical:

• Connector Type & Contact Configuration: Both are male pin headers with 2 positions in a single row
• Pitch Specification: 0.079" (2.00mm) mating pitch ensures mechanical and electrical compatibility
• Mounting & Termination: Through-hole, right-angle mounting with press-fit and solder termination options
• Electrical Ratings: 3A current rating and operating temperature range of -55°C to 105°C
• Compliance Standards: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating
• Fastening Mechanism: Push-pull fastening type for consistent mating interface

The DF3A-2P-2DS maintains the DF3A base product number series, confirming design continuity and full pin-to-pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-2P-2DS is the appropriate selection for applications currently using the obsolete DF3A-2P-2DS(18). The active substitute maintains identical electrical, mechanical, and thermal specifications, ensuring direct compatibility without design modification.

The DF3A-2P-2DS offers the following advantages for new designs and replacements:

• Active Production Status: Continuous manufacturing availability eliminates supply chain risk
• Enhanced Compliance: ROHS3 certification and explicit MSL 1 rating provide documented regulatory compliance
• Proven Reliability: Hirose Electric Co Ltd manufacturing ensures consistent quality and performance
• Thermal & Electrical Equivalence: Identical operating temperature range (-55°C to 105°C) and current rating (3A) support existing circuit requirements

No design changes are required when transitioning from the obsolete variant to the active DF3A-2P-2DS.

Frequently Asked Questions (FAQ)

Q: Can the DF3A-2P-2DS directly replace the DF3A-2P-2DS(18) without PCB modifications?

A: Yes. Both parts share identical connector type, pitch, mounting configuration, and electrical ratings. Direct substitution is supported without PCB layout changes.

Q: What is the significance of the "(18)" designation in the obsolete part number?

A: The "(18)" suffix typically indicates a specific manufacturing revision or packaging variant of the base DF3A-2P-2DS design. The active substitute DF3A-2P-2DS represents the current production equivalent.

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

A: The active DF3A-2P-2DS includes explicit ROHS3 compliance certification and MSL 1 rating documentation. These certifications confirm regulatory alignment with current environmental and moisture sensitivity standards.

Q: What is the mating pitch, and why is it critical for substitution?

A: The mating pitch is 0.079" (2.00mm), defining the center-to-center distance between connector positions. This specification must remain constant to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Q: Can the DF3A-2P-2DS be used in high-temperature applications?

A: Yes. The operating temperature range of -55°C to 105°C supports both industrial and consumer-grade applications within this thermal envelope.

Q: What termination options are available for the DF3A-2P-2DS?

A: The connector supports both press-fit and solder termination methods, providing flexibility for different assembly processes and PCB design requirements.
