Key Parameters

Substitute Part Grouping Explanation

The DF3EA-10P-2V(21) qualifies as a direct substitute for the DF3DZ-10P-2V(21) based on the following critical parameters:

• Connector Type & Contact Configuration: Both parts are header connectors with male pin contacts
• Position Count & Pitch: Identical 10-position arrangement at 2.00mm mating pitch
• Mechanical Interface: Matching shrouded 4-wall design, push-pull fastening, and surface mount termination
• Physical Dimensions: Identical insulation height of 0.232" (5.90mm)
• Material & Finish Specifications: Brass contacts with tin finish and polyamide insulation
• Compliance & Safety: Both rated UL94 V-0 and MSL 1
• Series Compatibility: Both belong to the DF3 series family

The DF3EA variant represents an active production alternative with extended operating temperature range and enhanced electrical specifications.

Engineering Selection Recommendations

The DF3EA-10P-2V(21) is the appropriate selection for applications currently using or specifying the obsolete DF3DZ-10P-2V(21). Key advantages include:

• Active Product Status: DF3EA maintains current manufacturing and supply chain support, eliminating obsolescence risk
• Extended Operating Range: Operating temperature range of -55°C to 105°C exceeds the original -30°C to 85°C specification, providing broader environmental compatibility
• RoHS Compliance: DF3EA is explicitly RoHS compliant, meeting modern regulatory requirements
• Mechanical Compatibility: Identical mechanical interface ensures direct PCB layout compatibility without redesign
• Electrical Equivalence: Matching contact materials, finishes, and current handling characteristics maintain electrical performance
• Packaging Availability: Tape & Reel packaging supports automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can DF3EA-10P-2V(21) be used as a direct replacement for DF3DZ-10P-2V(21)?

A: Yes. Both connectors share identical mechanical interfaces, contact configurations, and electrical specifications. The DF3EA variant is the active production equivalent with enhanced temperature range and RoHS compliance.

Q: What are the key compatibility criteria for this connector family?

A: Substitution is valid when the following parameters match: connector type (header), contact type (male pin), position count (10), mating pitch (2.00mm), shrouding (4-wall), mounting type (surface mount), and fastening mechanism (push-pull).

Q: Does the extended operating temperature of DF3EA affect PCB design?

A: No. The extended temperature range (-55°C to 105°C) does not alter mechanical dimensions, pitch, or mounting requirements. PCB layouts designed for DF3DZ are directly compatible with DF3EA.

Q: What is the significance of the packaging difference?

A: DF3DZ packaging is unspecified in available data. DF3EA is supplied in Tape & Reel format, which is standard for automated surface mount assembly. This improves handling efficiency and reduces component damage during manufacturing.

Q: Are there any electrical performance differences between these parts?

A: Both connectors use identical brass contacts with tin finish and polyamide insulation. The DF3EA specifies voltage rating of 250VAC and current rating varies by wire gauge, providing complete electrical equivalence for standard applications.

Q: What does RoHS compliance on DF3EA mean for my design?

A: RoHS compliance ensures the connector meets restrictions on hazardous substances, meeting regulatory requirements for products sold in regulated markets. This is a compliance advantage of the DF3EA over the obsolete DF3DZ.
