Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF63-2P-3.96DSA(01) is determined by strict alignment of the following critical parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 2
• Pitch - mating: 0.156" (3.96mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Latch Holder
• Voltage rating: 600VAC/DC
• Operating temperature range: -55°C ~ 105°C
• Insulation material: Polybutylene Terephthalate (PBT), Glass Filled
• Contact material: Brass
• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0

The substitute part DF63M-2P-3.96DSA(01) maintains all critical electrical and mechanical parameters required for direct substitution. Minor variations in contact post length (0.138" vs. 0.150") and additional compliance certifications do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The DF63M-2P-3.96DSA(01) is the direct substitute for the obsolete DF63-2P-3.96DSA(01). Selection of the substitute part is supported by the following factors:

• Both parts maintain identical electrical specifications: 600VAC/DC voltage rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability rating.
• Both parts share identical mechanical specifications: 2-position, 0.156" (3.96mm) pitch, shrouded 4-wall through-hole header configuration with solder termination and latch holder fastening.
• The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity.
• The substitute part meets ROHS3 compliance, providing enhanced regulatory alignment compared to the obsolete part's RoHS Compliant status.
• Contact post length variation (0.138" vs. 0.150") is within acceptable tolerance for standard solder joint formation on printed circuit boards.
• Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can DF63M-2P-3.96DSA(01) be used as a direct replacement for DF63-2P-3.96DSA(01)?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting method, shrouding, termination, and electrical ratings. The substitute part is functionally compatible for all standard applications.

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

A: The substitute part has a contact post length of 0.138" (4.60mm) compared to 0.150" (3.81mm) on the original part. This 0.012" (0.31mm) difference does not affect solder joint quality or electrical performance in standard through-hole PCB assembly processes.

Q: Why is the original part listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The availability of the active substitute part DF63M-2P-3.96DSA(01) provides a direct path for design continuity.

Q: Are there any compliance differences between the two parts?

A: The substitute part carries ROHS3 Compliant status and includes Glow Wire Compliance certification, providing enhanced regulatory coverage. Both parts maintain UL94 V-0 flammability rating and identical electrical specifications.

Q: What packaging options are available?

A: The original part was supplied in standard packaging. The substitute part is available in Bulk packaging, suitable for production assembly environments.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts are rated for -55°C to 105°C operating temperature, ensuring thermal compatibility across all standard industrial and commercial applications.
