DF3A-3P-2DS(18) Equivalent & Substitute Parts

Part Overview

The DF3A-3P-2DS(18) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable connections with a 3-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 This part is classified as obsolete and has been superseded in active production.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 original form, identifying functionally equivalent active alternatives is essential for ongoing design support, maintenance, and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3A-3P-2DS(18) is determined by the following critical parameters that must remain constant:

• Connector Type: Header (male pin contact orientation)
• Number of Positions: 3 positions
• Pitch - Mating: 0.079" (2.00mm) center-to-center spacing
• Number of Rows: Single row configuration
• Mounting Type: Through Hole, Right Angle orientation
• Manufacturer Series: DF3A series by Hirose Electric Co Ltd

The substitute part DF3A-3P-2DS maintains all these critical parameters while transitioning from obsolete to active product status. This ensures mechanical and electrical compatibility with existing PCB layouts and mating connectors designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-3P-2DS (active substitute) is the direct replacement for the obsolete DF3A-3P-2DS(18). Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active production status with confirmed inventory availability (7976 Pcs), ensuring long-term supply chain reliability compared to the obsolete original.

Compliance & Certifications: The active substitute carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in most markets. The original part's compliance status was not specified.

Mechanical & Electrical Compatibility: All critical dimensions, contact configurations, pitch spacing, and electrical ratings remain identical, ensuring direct PCB footprint compatibility and mating connector interchangeability.

Environmental & Thermal Performance: Both parts operate across the identical temperature range (-55°C ~ 105°C) with matching flammability ratings (UL94 V-0) and current capacity (3A), confirming functional equivalence under specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can DF3A-3P-2DS be used as a direct replacement for DF3A-3P-2DS(18)?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (2.00mm), contact configuration (3-position, single-row header), mounting type (through-hole, right-angle), and electrical ratings. The substitute is the active production equivalent.

Q: What is the difference between DF3A-3P-2DS(18) and DF3A-3P-2DS?

A: The primary difference is product status. DF3A-3P-2DS(18) is obsolete with limited availability. DF3A-3P-2DS is the active equivalent with full production support, improved compliance documentation (ROHS3, REACH), and confirmed inventory.

Q: Are there any packaging differences?

A: The original part packaging was not specified. The active substitute is supplied in bulk packaging, which is standard for this connector category.

Q: Will the substitute part fit existing PCB designs?

A: Yes. The substitute maintains identical footprint dimensions, hole spacing, and mounting orientation, requiring no PCB layout modifications.

Q: What is the MSL rating for the substitute part?

A: The active substitute carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: The active substitute DF3A-3P-2DS is ROHS3 compliant. The original part's RoHS status was not documented.
