Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF63M-4P-3.96DS(01) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Pitch specification (0.156" / 3.96mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Voltage and temperature ratings (600VAC/DC, -55°C ~ 105°C)
• Material compliance (UL94 V-0, RoHS)

The substitute part DF63-4P-3.96DS(01) maintains full electrical and mechanical compatibility with the main part across all specified parameters. The primary distinction is product status: the main part is Last Time Buy, while the substitute is Active production status.

Parameter Comparison

Engineering Selection Recommendations

The DF63-4P-3.96DS(01) is the direct substitute for the DF63M-4P-3.96DS(01). Both parts are manufactured by Hirose Electric Co Ltd within the EnerBee™ DF63 series and maintain identical electrical and mechanical specifications. The substitute part is currently in Active production status, providing assured long-term availability compared to the Last Time Buy status of the main part.

Both parts meet RoHS compliance requirements and UL94 V-0 flammability standards. The substitute carries RoHS Compliant certification, while the main part specifies ROHS3 Compliant status. Both are rated for identical voltage (600VAC/DC) and temperature (-55°C ~ 105°C) operating ranges.

The packaging difference (Bag versus Bulk) does not affect functional or mechanical compatibility and reflects only distribution format.

Frequently Asked Questions (FAQ)

Q: Can DF63-4P-3.96DS(01) be used as a direct replacement for DF63M-4P-3.96DS(01)?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including connector type, contact configuration, pitch, mounting style, voltage rating, and temperature range. The substitute is the manufacturer-recommended equivalent.

Q: What is the difference between the main part and the substitute?

A: The primary difference is product status. The DF63M-4P-3.96DS(01) is Last Time Buy, indicating discontinued production. The DF63-4P-3.96DS(01) is Active production. Additionally, packaging differs: the main part is supplied in Bag format, while the substitute is supplied in Bulk format. RoHS certification levels differ slightly (ROHS3 versus RoHS Compliant), but both meet regulatory requirements.

Q: Are there any compatibility concerns when switching from the main part to the substitute?

A: No compatibility concerns exist. Both parts share identical electrical ratings (600VAC/DC), temperature operating range (-55°C ~ 105°C), contact configuration (4-position male pin header), pitch (0.156" / 3.96mm), and mounting type (through-hole, right-angle). Mechanical dimensions and contact materials are identical.

Q: Does packaging format affect performance or installation?

A: No. Packaging format (Bag versus Bulk) is a distribution consideration only and does not affect electrical performance, mechanical fit, or installation characteristics.

Q: What compliance certifications apply to both parts?

A: Both parts meet UL94 V-0 flammability standards and RoHS compliance requirements. Both carry MSL 1 (Unlimited) moisture sensitivity rating. Both are rated for 600VAC/DC operation across -55°C to 105°C temperature range.
