Key Parameters

Substitute Part Grouping Explanation

The DF3EA-3P-2H(21) qualifies as a direct substitute for the DF3DZ-3P-2H(21) based on the following critical parameters:

• Series Compatibility: Both parts belong to the DF3 series
• Connector Configuration: Identical 3-position header with male pin contact type
• Pitch Specification: Matching 0.079" (2.00mm) mating pitch
• Mounting Geometry: Both feature surface mount, right-angle orientation with shrouded 4-wall design
• Electrical Performance: Identical operating temperature range (-55°C ~ 105°C) and material flammability rating (UL94 V-0)
• Compliance: Both are RoHS compliant with MSL 1 rating
• Termination Method: Both use solder termination with push-pull fastening

The primary distinction is product status: the DF3DZ variant is discontinued, while the DF3EA variant remains active with significantly higher inventory availability (4703 pcs vs. 868 pcs).

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-3P-2H(21) is the appropriate substitute for the discontinued DF3DZ-3P-2H(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector pitch, position count, mounting orientation, and operating temperature range. Both parts satisfy RoHS compliance and UL94 V-0 flammability requirements.

The DF3EA variant offers the advantage of active product status with substantially higher inventory availability, supporting long-term component procurement and supply chain continuity. The Tape & Reel packaging of the DF3EA variant is standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-3P-2H(21) and DF3EA-3P-2H(21) mechanically interchangeable?

A: Yes. Both parts feature identical mounting geometry, pitch specification (2.00mm), and right-angle surface mount orientation. They are mechanically interchangeable in board-level applications.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts operate within the same temperature range (-55°C ~ 105°C) and maintain identical contact material (brass with tin finish) and insulation specifications (polyamide/nylon).

Q: What is the difference between the DF3DZ and DF3EA variants?

A: The primary difference is product lifecycle status. The DF3DZ is discontinued, while the DF3EA remains active. The DF3EA is supplied in Tape & Reel packaging, which is standard for automated assembly. Both parts are functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF3DZ-3P-2H(21) and DF3EA-3P-2H(21) are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use the DF3EA-3P-2H(21) as a direct replacement in existing designs?

A: Yes. The DF3EA-3P-2H(21) is a direct functional and mechanical substitute. No design modifications are required for component substitution.
