DF3DZ-4P-2V(21) Equivalent & Substitute Parts

Part Overview

The DF3DZ-4P-2V(21) is a surface mount rectangular connector header manufactured by Hirose Electric Co., Ltd., designed for board-to-board or cable applications with 4 positions at 2.00mm pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part features shrouded 4-wall construction, solder termination, and push-pull fastening, suitable for applications requiring reliable low-profile interconnection.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3DZ-4P-2V(21) is determined by the following critical parameters that must remain consistent:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 4
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Material: Brass
• Contact Finish: Tin
• Insulation Material: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The DF3EA-4P-2V(21) from Hirose Electric Co., Ltd. is a direct equivalent within the same manufacturer's DF3 series, maintaining all critical electrical and mechanical parameters while offering active product status and extended operating temperature range. The 292175-4 from TE Connectivity AMP Connectors represents a cross-manufacturer substitute that preserves core mating characteristics and connector geometry, though with variations in contact shape, insulation height, and fastening mechanism.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-4P-2V(21) is the primary substitute for the obsolete DF3DZ-4P-2V(21). Both parts are manufactured by Hirose Electric Co., Ltd. within the DF3 series and maintain identical pitch, position count, shrouding configuration, and contact geometry. The DF3EA-4P-2V(21) offers active product status, extended operating temperature range (-55°C to 105°C versus -30°C to 85°C), ROHS3 compliance, and higher voltage rating (250VAC), making it suitable for designs requiring long-term component availability and enhanced environmental performance.

The 292175-4 from TE Connectivity AMP Connectors serves as an alternative cross-manufacturer substitute when Hirose parts are unavailable. This part maintains the critical 2.00mm pitch and 4-position configuration with identical shrouding and solder termination. However, design integration requires consideration of mechanical differences: increased insulation height (0.307" versus 0.232"), square contact geometry (versus circular), detent lock fastening (versus push-pull), and glass-filled nylon insulation. The 292175-4 carries RoHS compliance and MSL 1 rating, supporting modern manufacturing requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-4P-2V(21) directly replace the DF3DZ-4P-2V(21) without PCB redesign?

A: Yes. Both parts share identical pitch (2.00mm), position count (4), shrouding (4-wall), and solder termination. Footprint compatibility is maintained. The DF3EA-4P-2V(21) is the recommended direct substitute.

Q: What are the key differences between DF3EA-4P-2V(21) and 292175-4?

A: The DF3EA-4P-2V(21) maintains the same manufacturer (Hirose) and identical contact shape (circular). The 292175-4 introduces three mechanical variations: increased insulation height (7.80mm vs. 5.90mm), square contact geometry, and detent lock fastening instead of push-pull. These differences may require PCB layout verification and mating connector compatibility assessment.

Q: Is the 292175-4 suitable for applications requiring push-pull fastening?

A: No. The 292175-4 uses detent lock fastening, which differs from the push-pull mechanism of the original part. Applications dependent on push-pull engagement require the DF3EA-4P-2V(21) or equivalent Hirose DF3 series parts.

Q: What packaging options are available for substitute parts?

A: The DF3EA-4P-2V(21) is supplied in Tape & Reel (TR) packaging. The 292175-4 is also supplied in Tape & Reel (TR) packaging. Both support automated assembly processes.

Q: Are both substitute parts RoHS compliant?

A: Yes. The DF3EA-4P-2V(21) is ROHS3 compliant. The 292175-4 is RoHS compliant. Both meet modern environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All three parts—DF3DZ-4P-2V(21), DF3EA-4P-2V(21), and 292175-4—carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
