Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF36-40P-0.4SD is determined by strict equivalence across the following critical parameters:

• Series designation (DF36)
• Connector type (Plug)
• Number of positions (40)
• Contact pitch (0.016" / 0.40mm)
• Contact type (Outer Shroud Contact)
• Cable termination method (Solder)
• Wire gauge compatibility (42-46 AWG)
• Contact finish (Gold)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Latch Holder)

The substitute part DF36-40P-0.4SD(51) maintains identical electrical and mechanical specifications to the main part, with the primary distinction being packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The DF36-40P-0.4SD(51) serves as the direct functional equivalent to the obsolete DF36-40P-0.4SD. Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical connector parameters.

The primary distinction between these parts is product lifecycle status. The DF36-40P-0.4SD(51) is classified as active and carries RoHS compliance certification, making it the appropriate selection for new designs and ongoing procurement. The DF36-40P-0.4SD(51) is supplied in Tape & Reel packaging format, which is standard for production environments.

For applications currently utilizing the obsolete DF36-40P-0.4SD, direct substitution with DF36-40P-0.4SD(51) is supported without design modification, as all functional parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can DF36-40P-0.4SD(51) be used as a direct replacement for DF36-40P-0.4SD?

A: Yes. Both parts are identical in electrical and mechanical specifications. The DF36-40P-0.4SD(51) is the active production variant and can be substituted without design changes.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), and RoHS compliance certification. The connector itself is functionally identical.

Q: Are there any compatibility concerns when switching from DF36-40P-0.4SD to DF36-40P-0.4SD(51)?

A: No compatibility concerns exist. Both parts maintain the same 40-position configuration, 0.016" pitch, solder termination, and gold contact finish. Mechanical and electrical performance are equivalent.

Q: What does the "(51)" designation indicate?

A: The "(51)" suffix indicates the Tape & Reel packaging variant of the base DF36-40P-0.4SD connector series.

Q: Is DF36-40P-0.4SD(51) RoHS compliant?

A: Yes, DF36-40P-0.4SD(51) is RoHS compliant. The original DF36-40P-0.4SD compliance status is not specified in available documentation.

Q: What wire gauges are compatible with these connectors?

A: Both parts support discrete wire termination with 42-46 AWG wire gauge.
