Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2H(24) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical series designation (DF3)
• Matching connector type (Header) and contact type (Male Pin)
• Same number of positions (4) and mating pitch (0.079" / 2.00mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching shrouding design (Shrouded - 4 Wall)
• Equivalent electrical ratings (250VAC, -55°C ~ 105°C)
• Same material flammability compliance (UL94 V-0)
• Identical termination method (Solder) and fastening type (Push-Pull)

The substitute part differs only in product status (Last Time Buy versus Obsolete) and packaging format (Tube versus unspecified), with no functional or electrical parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2H(24) is the direct equivalent for the obsolete DF3E-4P-2H(20). Both parts maintain identical electrical and mechanical specifications, including voltage rating, operating temperature range, and material compliance certifications. The DF3E-4P-2H(24) carries Last Time Buy status, indicating limited future availability. For new designs or long-term production requirements, procurement planning should account for this status constraint. Both parts comply with UL94 V-0 flammability standards and carry unlimited moisture sensitivity classification, suitable for standard industrial applications without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can DF3E-4P-2H(24) be used as a direct replacement for DF3E-4P-2H(20)?

A: Yes. Both parts are functionally identical across all electrical and mechanical parameters. The connector type, position count, pitch, mounting configuration, voltage rating, and temperature range are equivalent. Substitution is valid for all applications where the original part was specified.

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

A: The primary differences are product status and packaging. DF3E-4P-2H(20) is obsolete, while DF3E-4P-2H(24) is Last Time Buy status. DF3E-4P-2H(24) is supplied in Tube packaging. No functional or electrical differences exist between the parts.

Q: Are there any compatibility concerns with PCB layout or mating connectors?

A: No. Identical pitch (2.00mm), shrouding design, and contact configuration ensure full compatibility with existing PCB layouts and mating connector designs. No redesign is required.

Q: What does Last Time Buy status mean for DF3E-4P-2H(24)?

A: Last Time Buy indicates this part will be discontinued after a specified date. Procurement should plan accordingly for long-term production needs, as future availability will be limited.

Q: Are both parts RoHS compliant?

A: DF3E-4P-2H(24) is explicitly marked as RoHS Compliant. DF3E-4P-2H(20) RoHS status is not specified in available documentation.
