Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2V(21) qualifies as a direct substitute for the DF3DZ-2P-2V(75) based on the following critical parameters that determine functional compatibility:

• Series Alignment: Both parts belong to the DF3 series, ensuring mechanical and electrical compatibility within the connector family
• Position Count & Pitch: Identical 2-position configuration with 0.079" (2.00mm) mating pitch
• Mounting & Fastening: Both are surface mount headers with push-pull fastening mechanisms
• Shrouding & Insulation: Matching shrouded 4-wall design with identical insulation height (0.232" / 5.90mm) and material composition (Polyamide/Nylon)
• Contact Configuration: Both feature male pin contacts with circular contact shape
• Compliance & Safety: Both maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level
• Termination Method: Both use solder termination for PCB attachment

The primary distinction is product status: the DF3DZ-2P-2V(75) is discontinued, while the DF3EA-2P-2V(21) remains active with significantly higher inventory availability (13,145 pcs vs. 696 pcs).

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2V(21) is the appropriate substitute for the discontinued DF3DZ-2P-2V(75). Selection is based on:

• Product Continuity: The DF3EA-2P-2V(21) maintains active status with robust inventory levels, ensuring supply chain reliability for new designs and production runs
• Compliance Equivalence: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity classification
• Enhanced Specifications: The substitute offers an expanded operating temperature range (-55°C ~ 105°C vs. -30°C ~ 85°C) and ROHS3 compliance, providing greater flexibility for diverse application environments
• Mechanical & Electrical Parity: Identical connector geometry, pitch, position count, and fastening mechanisms ensure direct PCB layout compatibility without redesign

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-2P-2V(21) be used as a direct replacement for the DF3DZ-2P-2V(75) without PCB modification?

A: Yes. Both connectors share identical mechanical dimensions, mating pitch (2.00mm), position count (2), shrouding configuration (4-wall), and mounting type (surface mount). PCB footprints and assembly processes remain unchanged.

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

A: The primary differences are product status (discontinued vs. active), packaging format (bulk vs. tape & reel), and operating temperature range. The DF3EA-2P-2V(21) provides an extended temperature specification (-55°C ~ 105°C) compared to the DF3DZ-2P-2V(75) (-30°C ~ 85°C).

Q: Are there any compliance or certification differences?

A: Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity. The substitute carries ROHS3 compliance versus RoHS compliance on the original part, representing an updated regulatory standard.

Q: What packaging options are available for the substitute part?

A: The DF3EA-2P-2V(21) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original DF3DZ-2P-2V(75) packaging format is not specified in available data.

Q: Is the substitute part available in sufficient quantity?

A: Yes. The DF3EA-2P-2V(21) has 13,145 pcs in stock, compared to 696 pcs for the discontinued original part, providing reliable supply for production requirements.
