Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2H(54) qualifies as a direct substitute based on the following critical parameters:

• Connector Series & Type: Both parts belong to the DF3 series and function as shrouded headers with identical male pin contact configuration
• Electrical Specifications: Matching 4-position layout, 2.00mm pitch, 250VAC voltage rating, and -55°C ~ 105°C operating temperature range
• Mechanical Compatibility: Identical surface mount, right-angle mounting orientation with shrouded 4-wall design and push-pull fastening
• Material & Compliance: Both feature brass contacts with gold finish, polyamide insulation, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1)
• Termination Method: Both use solder termination with board guide and solder retention features

The primary distinction is product status: DF3E-4P-2H(50) is obsolete, while DF3E-4P-2H(54) is designated Last Time Buy with higher current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2H(54) is the direct functional equivalent for applications currently using DF3E-4P-2H(50). Selection is based on:

• Electrical & Mechanical Equivalence: All critical parameters including pitch, position count, voltage rating, temperature range, and mounting configuration are identical
• Compliance Status: DF3E-4P-2H(54) carries RoHS Compliant certification, providing regulatory advantage for new designs and procurement cycles
• Product Lifecycle: DF3E-4P-2H(54) is designated Last Time Buy with 910 units in current inventory, compared to the obsolete status of DF3E-4P-2H(50)
• Packaging Availability: DF3E-4P-2H(54) is supplied in tube packaging, supporting standard assembly and handling workflows

No design modifications are required for substitution. PCB layouts, mating connector specifications, and electrical circuit parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can DF3E-4P-2H(54) be used as a direct replacement for DF3E-4P-2H(50) without PCB redesign?

A: Yes. Both parts share identical pitch (2.00mm), position count (4), mounting type (surface mount right-angle), and electrical ratings (250VAC, -55°C ~ 105°C). No PCB layout modifications are necessary.

Q: What is the difference between DF3E-4P-2H(50) and DF3E-4P-2H(54)?

A: The primary differences are product status and packaging. DF3E-4P-2H(50) is obsolete, while DF3E-4P-2H(54) is Last Time Buy with RoHS Compliant certification and tube packaging. All electrical and mechanical specifications are equivalent.

Q: Is DF3E-4P-2H(54) RoHS compliant?

A: Yes, DF3E-4P-2H(54) is RoHS Compliant. RoHS status is not specified for DF3E-4P-2H(50).

Q: What packaging is available for DF3E-4P-2H(54)?

A: DF3E-4P-2H(54) is supplied in tube packaging, suitable for standard pick-and-place assembly operations.

Q: Are the contact finishes identical between these parts?

A: Both parts feature gold-plated mating contacts. DF3E-4P-2H(54) specifies additional contact finish thickness data (8.00µin / 0.203µm) for both mating and post contacts, providing enhanced specification documentation.

Q: What is the current inventory status?

A: DF3E-4P-2H(50) has 878 units listed as new original in stock. DF3E-4P-2H(54) has 910 units available. Given the obsolete status of DF3E-4P-2H(50), DF3E-4P-2H(54) is the recommended procurement choice.
