Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2H(51) qualifies as a direct substitute based on the following critical parameters:

• Series alignment: Both parts belong to the DF3 series
• Connector configuration: 2-position header with male pin contacts
• Pitch specification: Identical 0.079" (2.00mm) mating pitch
• Mounting and orientation: Surface mount, right-angle configuration
• Shrouding design: Shrouded 4-wall structure
• Termination method: Solder termination with push-pull fastening
• Operating temperature range: -55°C ~ 105°C
• Material compliance: UL94 V-0 flammability rating
• Moisture sensitivity: MSL 1 (Unlimited)
• Contact material and finish: Brass with gold plating

The primary distinction is product status: DF3DZ-2P-2H(51) is discontinued, while DF3EA-2P-2H(51) is active with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2H(51) is the direct functional equivalent for applications currently using DF3DZ-2P-2H(51). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The DF3EA variant offers the advantage of active product status with substantially higher inventory levels, supporting both immediate procurement and long-term supply chain continuity.

The DF3EA-2P-2H(51) is supplied in Tape & Reel packaging, suitable for automated assembly processes. Both parts carry equivalent compliance certifications: RoHS compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. The upgrade from RoHS to ROHS3 compliance in the substitute part reflects current regulatory standards without affecting functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-2P-2H(51) and DF3EA-2P-2H(51) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3A current rating, operating temperature range of -55°C to 105°C, contact material (brass with gold plating), and termination method (solder with push-pull fastening).

Q: What are the mechanical differences between these parts?

A: There are no mechanical differences. Both connectors feature 2-position headers with 2.00mm pitch, surface mount right-angle mounting, shrouded 4-wall design, and 0.220" insulation height.

Q: Does packaging affect compatibility?

A: Packaging does not affect functional compatibility. The DF3DZ-2P-2H(51) packaging is unspecified, while DF3EA-2P-2H(51) is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly and does not alter the connector's electrical or mechanical performance.

Q: Why is the DF3DZ variant discontinued?

A: Product discontinuation is a manufacturer decision typically driven by market consolidation or product line rationalization. The DF3EA-2P-2H(51) serves as the active continuation within the DF3 series.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The DF3EA-2P-2H(51) carries ROHS3 compliance, representing the current regulatory standard. Both maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What is the inventory situation for each part?

A: DF3DZ-2P-2H(51) has 807 pieces available. DF3EA-2P-2H(51) has 27,430 pieces in stock, providing significantly greater availability for production requirements.
