Key Parameters

Substitute Part Grouping Explanation

The DF3E-8P-2V(24) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical pitch specification: 0.079" (2.00mm)
• Identical number of positions: 8
• Identical connector type: Header with male pin contacts
• Identical mounting type: Surface Mount
• Identical shrouding configuration: Shrouded - 4 Wall
• Identical termination method: Solder
• Identical fastening type: Push-Pull
• Identical voltage rating: 250VAC
• Identical operating temperature range: -55°C ~ 105°C
• Identical material flammability rating: UL94 V-0
• Same base product number: DF3

The substitution is valid across all electrical and mechanical interfaces. Differences in packaging format (Tube for DF3E-8P-2V(24)) and insulation color (Black vs. Beige) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-8P-2V(24) is a direct functional equivalent to the DF3E-8P-2V(20) for all electrical and mechanical applications. Selection of the substitute part is supported by:

• Identical electrical specifications across all rated parameters
• Identical mechanical interface dimensions and mounting requirements
• Improved product status (Last Time Buy vs. Obsolete) providing extended procurement window
• RoHS Compliance certification on the substitute part, meeting modern regulatory requirements
• Identical UL94 V-0 flammability rating and MSL classification

The insulation color difference (Black vs. Beige) and packaging format (Tube vs. unspecified) present no functional impact on circuit performance or board assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF3E-8P-2V(24) be used as a direct replacement for DF3E-8P-2V(20) in existing designs?

A: Yes. All electrical and mechanical parameters are identical, including pitch, position count, voltage rating, temperature range, and contact specifications. The parts are functionally interchangeable at the circuit and assembly level.

Q: What is the significance of the product status change from Obsolete to Last Time Buy?

A: The Obsolete status of DF3E-8P-2V(20) indicates end-of-life with no further manufacturing. The Last Time Buy status of DF3E-8P-2V(24) indicates a defined final procurement window before discontinuation. This provides a transition path for designs requiring this connector type.

Q: Does the insulation color difference affect compatibility?

A: No. Insulation color is a visual identifier only and does not affect electrical performance, mechanical fit, or functional operation. Both parts use identical Polyamide (PA) Nylon material.

Q: What is the impact of the packaging difference?

A: Packaging format (Tube for DF3E-8P-2V(24)) affects logistics and handling but does not impact the connector's electrical or mechanical performance. Assembly compatibility remains unchanged.

Q: Is RoHS Compliance a requirement for substitution?

A: RoHS Compliance is specified for DF3E-8P-2V(24) but not documented for DF3E-8P-2V(20). If RoHS compliance is required for your application, DF3E-8P-2V(24) meets this regulatory requirement.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts share identical operating temperature range (-55°C ~ 105°C), voltage rating (250VAC), contact material (Brass with Tin finish), and current rating specifications.
