Key Parameters

Substitute Part Grouping Explanation

The DF3E-3P-2H(54) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Series Match: Both parts belong to the DF3 series from Hirose Electric Co Ltd
• Connector Configuration: Identical 3-position header with male pin contacts
• Pitch Specification: Both maintain 0.079" (2.00mm) mating pitch
• Mounting and Orientation: Both are surface mount, right-angle configurations
• Shrouding Design: Both feature shrouded 4-wall construction
• Termination Method: Both use solder termination with push-pull fastening
• Electrical Ratings: Both rated for 250VAC operation
• Temperature Range: Both operate across -55°C ~ 105°C
• Flammability Compliance: Both meet UL94 V-0 material flammability rating
• Moisture Sensitivity: Both classified as MSL 1 (Unlimited)

The primary distinction between these parts is product status: DF3E-3P-2H(50) is obsolete, while DF3E-3P-2H(54) is active with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-3P-2H(54) is the direct active equivalent for the obsolete DF3E-3P-2H(50). Selection of the substitute part is based on:

• Product Status Alignment: The DF3E-3P-2H(54) maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute part carries explicit ROHS3 compliance certification, meeting current environmental and material restriction requirements
• Identical Electrical and Mechanical Specifications: All critical parameters including connector configuration, pitch, mounting orientation, termination method, and operating ratings are identical
• Packaging Availability: The substitute is supplied in tube packaging with higher current inventory levels (1303 units versus 867 units)
• Certification Maintenance: Both parts maintain identical REACH unaffected status and EAR99 export classification

No design modifications or PCB layout adjustments are required when transitioning from DF3E-3P-2H(50) to DF3E-3P-2H(54).

Frequently Asked Questions (FAQ)

Q: Can DF3E-3P-2H(54) be used as a direct replacement for DF3E-3P-2H(50) without PCB modifications?

A: Yes. Both parts share identical mechanical and electrical specifications including pitch, mounting type, shrouding configuration, and contact arrangement. No PCB layout changes are necessary.

Q: What is the difference between the insulation colors (Beige vs. Natural)?

A: Insulation color is a cosmetic specification that does not affect electrical performance or mechanical compatibility. Both colors represent the same material composition and functional characteristics.

Q: Does the DF3E-3P-2H(54) meet RoHS requirements?

A: Yes. The DF3E-3P-2H(54) is ROHS3 compliant. The original DF3E-3P-2H(50) RoHS status was not specified in available documentation.

Q: Are there any differences in contact finish specifications between these parts?

A: Both parts feature gold-plated mating contacts. The DF3E-3P-2H(54) specifies additional contact finish thickness data (8.00µin / 0.203µm) for both mating and post contacts, providing more detailed specification information.

Q: What is the packaging difference between these parts?

A: The DF3E-3P-2H(54) is supplied in tube packaging. The original part packaging specification was not provided. Tube packaging is standard for surface mount connector components.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -55°C ~ 105°C and maintain identical UL94 V-0 flammability ratings.
