DF63-2P-3.96DSA Equivalent & Substitute Parts

Part Overview

The DF63-2P-3.96DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, part of the EnerBee™ DF63 series. This through-hole mounted connector features a 2-position vertical configuration with 0.156" (3.96mm) pitch spacing, designed for board-to-cable/wire applications. The connector is currently listed as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

The DF63M-2P-3.96DSA qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Configuration: Both are header connectors with identical 2-position, single-row configuration
• Pitch Specification: Both maintain 0.156" (3.96mm) mating pitch, ensuring mechanical and electrical compatibility with existing mating connectors
• Mounting & Termination: Both feature through-hole mounting with solder termination
• Shrouding Design: Both employ shrouded 4-wall construction
• Electrical Ratings: Both support 600VAC/DC voltage rating and identical operating temperature range (-55°C ~ 105°C)
• Material & Compliance: Both use PBT glass-filled insulation with UL94 V-0 flammability rating and RoHS compliance
• Contact Material & Finish: Both utilize brass contacts with tin finish

The primary distinction is product status: DF63-2P-3.96DSA is obsolete, while DF63M-2P-3.96DSA is active production.

Parameter Comparison

Engineering Selection Recommendations

The DF63M-2P-3.96DSA is the direct substitute for the obsolete DF63-2P-3.96DSA. Selection of the active part is justified by:

• Product Lifecycle Status: The substitute is in active production, ensuring long-term availability and supply chain stability
• Regulatory Compliance: The substitute meets ROHS3 compliance, representing current regulatory standards, while maintaining all existing certifications (UL94 V-0, EAR99)
• Mechanical Compatibility: Identical pitch, shrouding, and mounting specifications ensure drop-in compatibility with existing mating connectors and PCB layouts
• Electrical Equivalence: Matching voltage and temperature ratings confirm functional equivalence for all specified operating conditions
• Contact Geometry: Minor variation in post contact length (0.150" vs 0.138") remains within acceptable tolerance for standard through-hole solder joint formation

Frequently Asked Questions (FAQ)

Q: Can DF63M-2P-3.96DSA be used as a direct replacement for DF63-2P-3.96DSA?

A: Yes. Both connectors share identical pitch (0.156"), position count (2), mounting type (through-hole), shrouding configuration (4-wall), and electrical ratings (600VAC/DC). The substitute is mechanically and electrically compatible with existing mating connectors and PCB designs.

Q: What is the significance of the contact post length difference?

A: The main part specifies 0.150" (3.81mm) post length, while the substitute specifies 0.138" (3.50mm). This 0.012" (0.31mm) difference is within standard PCB through-hole tolerance and does not affect solder joint integrity or electrical performance for standard board thicknesses.

Q: Are there compliance differences between the two parts?

A: The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard and includes all RoHS requirements. Both parts maintain UL94 V-0 flammability rating and identical electrical specifications.

Q: What is the inventory status for each part?

A: DF63-2P-3.96DSA (obsolete) has 818 pieces in stock. DF63M-2P-3.96DSA (active) has 909 pieces in stock. The active substitute ensures continued availability for future production requirements.

Q: Are there any feature differences?

A: The main part lists "Board Guide" as a feature. The substitute lists "Board Guide" and "Glow Wire Compliant" as features. Glow wire compliance represents an additional safety certification that does not affect mechanical or electrical compatibility.
