Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3DZ-3P-2H(51) is determined by strict equivalence across the following critical parameters:

• Connector series and manufacturer (Hirose Electric DF3 series)
• Contact configuration: 3-position, male pin header
• Pitch specification: 0.079" (2.00mm) mating pitch
• Mounting method: Surface mount, right-angle orientation
• Shrouding design: Shrouded 4-wall construction
• Termination type: Solder connection
• Fastening mechanism: Push-pull engagement
• Environmental ratings: Operating temperature range -55°C to 105°C
• Compliance: RoHS compliant, UL94 V-0 flammability rating

The DF3EA-3P-2H(51) qualifies as a direct substitute based on full alignment with these parameters. The primary distinction is product status: DF3EA-3P-2H(51) is currently active in inventory, whereas DF3DZ-3P-2H(51) is discontinued.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-3P-2H(51) is the direct equivalent for applications currently using DF3DZ-3P-2H(51). Selection is based on the following factors:

Product Status: DF3EA-3P-2H(51) maintains active status with 10,424 pieces in stock, whereas DF3DZ-3P-2H(51) is discontinued. For new designs and ongoing production, DF3EA-3P-2H(51) ensures supply continuity.

Compliance and Certification: Both parts maintain identical RoHS compliance, UL94 V-0 flammability rating, and EAR99 export classification. No compliance gaps exist between the two parts.

Electrical and Mechanical Equivalence: All critical parameters—contact configuration, pitch, mounting orientation, shrouding design, termination method, and operating temperature range—are identical. Direct board-level substitution is supported without design modification.

Packaging Consideration: DF3EA-3P-2H(51) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Verify packaging requirements for your production environment.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-3P-2H(51) be used as a direct replacement for DF3DZ-3P-2H(51) without PCB redesign?

A: Yes. Both connectors share identical electrical and mechanical specifications, including contact configuration, pitch, mounting type, and operating temperature range. No PCB layout modifications are required.

Q: What is the primary difference between these two part numbers?

A: The DF3DZ-3P-2H(51) is discontinued, while DF3EA-3P-2H(51) is currently active with available inventory. The DF3EA variant also includes solder retention features and is supplied in Tape & Reel packaging.

Q: Are the contact ratings identical between both parts?

A: The DF3DZ-3P-2H(51) specifies a fixed 3A current rating. The DF3EA-3P-2H(51) current rating varies by wire gauge. For applications requiring the fixed 3A specification, verify wire gauge compatibility with the DF3EA variant.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS compliant, rated UL94 V-0 for flammability, classified as EAR99 for export, and maintain MSL 1 (Unlimited) moisture sensitivity level. Operating temperature range is identical at -55°C to 105°C.

Q: What packaging format is DF3EA-3P-2H(51) supplied in?

A: DF3EA-3P-2H(51) is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. Confirm compatibility with your assembly equipment and processes.

Q: Are there any design considerations when transitioning from DF3DZ to DF3EA?

A: No design changes are required. Both connectors use identical shrouded 4-wall construction, push-pull fastening, and solder termination. Verify that your assembly process accommodates Tape & Reel packaging if transitioning from bulk packaging.
