Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2H(21) 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 contact type
• Pitch specification: Identical 0.079" (2.00mm) mating pitch
• Mounting geometry: Surface mount, right-angle orientation
• Shrouding design: Shrouded 4-wall construction
• Insulation height: 0.220" (5.60mm)
• 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 tin plating

The primary distinction is product status: DF3DZ-2P-2H(21) is discontinued, while DF3EA-2P-2H(21) is active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2H(21) is the appropriate selection for new designs and procurement due to active product status and ROHS3 compliance. Both parts meet identical electrical and mechanical specifications within the DF3 series, ensuring direct functional compatibility. The DF3EA variant includes solder retention features and is available in Tape & Reel packaging, supporting automated assembly processes. Inventory levels for the DF3EA-2P-2H(21) significantly exceed the discontinued DF3DZ variant, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-2P-2H(21) replace DF3DZ-2P-2H(21) in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (2), mounting type (surface mount right-angle), shrouding design (4-wall), and operating temperature range (-55°C ~ 105°C). Electrical and mechanical compatibility is direct.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current regulatory standard with updated substance restrictions. Both certifications indicate compliance with hazardous substance limitations. ROHS3 compliance on the DF3EA-2P-2H(21) reflects current manufacturing standards.

Q: Does packaging affect connector performance?

A: No. Tape & Reel (TR) packaging on the DF3EA-2P-2H(21) is a supply format that supports automated pick-and-place assembly. The connector itself performs identically regardless of packaging method.

Q: Are there any current rating differences?

A: The DF3DZ-2P-2H(21) specifies 3A current rating. The DF3EA-2P-2H(21) current rating varies by wire gauge. Both operate within the same thermal and electrical envelope for standard 2-position header applications.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled under standard conditions without special desiccant packaging or baking procedures.
