Key Parameters

Substitute Part Grouping Explanation

The DF3E-5P-2H(54) qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Connector Series: Both parts belong to the DF3 series
• Number of Positions: Identical at 5 positions
• Pitch - Mating: Both use 0.079" (2.00mm) pitch
• Mounting Type: Both are surface mount, right-angle configurations
• Shrouding: Both feature shrouded 4-wall construction
• Contact Type: Both use male pin contacts
• Fastening Type: Both employ push-pull fastening
• Voltage Rating: Both rated at 250VAC
• Operating Temperature Range: Both operate from -55°C to 105°C
• Material Flammability Rating: Both meet UL94 V-0
• Termination Method: Both use solder termination

The primary distinction is product status: DF3E-5P-2H(50) is obsolete, while DF3E-5P-2H(54) is listed as Last Time Buy with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-5P-2H(54) is the direct functional equivalent for the obsolete DF3E-5P-2H(50). Selection of the substitute part is based on:

• Electrical Compatibility: Identical electrical specifications including voltage rating, operating temperature range, and contact materials ensure direct functional replacement
• Mechanical Compatibility: Matching pitch, position count, mounting type, and shrouding configuration provide identical PCB footprint compatibility
• Regulatory Compliance: DF3E-5P-2H(54) carries RoHS compliance certification, meeting current environmental and regulatory requirements
• Product Lifecycle Status: DF3E-5P-2H(54) is designated Last Time Buy, providing a defined procurement window before complete discontinuation

For new designs or redesigns, DF3E-5P-2H(54) should be specified. For existing inventory management of DF3E-5P-2H(50), the substitute provides equivalent performance without design modification.

Frequently Asked Questions (FAQ)

Q: Can DF3E-5P-2H(54) be used as a direct replacement for DF3E-5P-2H(50) without PCB redesign?

A: Yes. Both parts share identical pitch (2.00mm), position count (5), mounting type (surface mount right-angle), and shrouding configuration. PCB footprints are compatible without modification.

Q: What is the difference between DF3E-5P-2H(50) and DF3E-5P-2H(54)?

A: The primary differences are product status and compliance certification. DF3E-5P-2H(50) is obsolete, while DF3E-5P-2H(54) is Last Time Buy with RoHS compliance. Electrical and mechanical specifications are identical.

Q: Does DF3E-5P-2H(54) meet RoHS requirements?

A: Yes, DF3E-5P-2H(54) is RoHS compliant. DF3E-5P-2H(50) does not specify RoHS status.

Q: Are the contact finishes identical between the two parts?

A: Both parts feature gold-plated mating contacts. DF3E-5P-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 packaging is available for the substitute part?

A: DF3E-5P-2H(54) is supplied in tube packaging. DF3E-5P-2H(50) packaging is not specified in available documentation.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate identically across the -55°C to 105°C temperature range and are rated for 250VAC. No derating or operational adjustments are required.
