DF3Z-2P-2H(51) Equivalent & Substitute Parts

Part Overview

The DF3Z-2P-2H(51) is a rectangular connector header manufactured by Hirose Electric Co., Ltd., designed for surface mount, right-angle board-to-board or cable applications. This connector features a 2-position configuration with 2.00mm pitch and is classified as a shrouded 4-wall header with solder termination and push-pull fastening.

The DF3Z-2P-2H(51) is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement. The substitute part DF3E-2P-2H(51) maintains electrical and mechanical compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the DF3Z-2P-2H(51) with the DF3E-2P-2H(51) is based on equivalence across all critical electrical and mechanical parameters:

Matching Parameters:

• Connector type, contact type, and position count (Header, Male Pin, 2-position)
• Mating pitch (0.079" / 2.00mm)
• Mounting configuration (Surface Mount, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Insulation height (0.220" / 5.60mm)
• Contact geometry and material (Circular, Brass with Gold finish)
• Insulation composition (Polyamide/Nylon)
• Operating temperature range (-55°C ~ 105°C)
• Flammability rating (UL94 V-0)
• Regulatory compliance (RoHS Compliant, MSL 1)

The DF3E variant represents an active product line continuation within the DF3 series, maintaining full mechanical and electrical interchangeability with the discontinued DF3Z model.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-2P-2H(51) is the direct functional equivalent for the discontinued DF3Z-2P-2H(51). Both components share identical electrical and mechanical specifications, including connector architecture, contact configuration, operating temperature range, and regulatory certifications.

Selection of the DF3E-2P-2H(51) is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Full compliance with RoHS directives and UL94 V-0 flammability requirements
• Identical MSL classification (1 - Unlimited) eliminating moisture sensitivity concerns
• Matching ECCN and HTSUS classifications for regulatory consistency
• Equivalent performance across all specified electrical and mechanical parameters

The DF3E variant maintains the same base product line designation (DF3 series) and represents the current production equivalent within Hirose Electric's connector portfolio.

Frequently Asked Questions (FAQ)

Q: Are the DF3Z-2P-2H(51) and DF3E-2P-2H(51) mechanically interchangeable?

A: Yes. Both connectors feature identical mounting type (Surface Mount, Right Angle), shrouding configuration (Shrouded - 4 Wall), insulation height (0.220" / 5.60mm), and contact geometry. They are direct mechanical replacements.

Q: Do these connectors have the same electrical specifications?

A: Yes. Both maintain identical contact material (Brass), contact finish (Gold), operating temperature range (-55°C ~ 105°C), and flammability rating (UL94 V-0). The mating pitch (0.079" / 2.00mm) and position count (2) are identical.

Q: What is the difference between the DF3Z and DF3E variants?

A: The DF3Z-2P-2H(51) is discontinued at DiGi Electronics, while the DF3E-2P-2H(51) maintains active product status. Both are part of the DF3 series and share all critical electrical and mechanical parameters. The DF3E represents the current production line continuation.

Q: Are there packaging differences between these parts?

A: The DF3Z-2P-2H(51) packaging is not specified in available data. The DF3E-2P-2H(51) is supplied in Tape & Reel (TR) format. Confirm packaging requirements with your procurement specifications.

Q: Do both connectors meet RoHS compliance requirements?

A: Yes. Both the DF3Z-2P-2H(51) and DF3E-2P-2H(51) are RoHS Compliant with MSL classification of 1 (Unlimited), indicating no moisture sensitivity limitations.

Q: Can I use the DF3E-2P-2H(51) as a direct replacement in existing designs?

A: Yes. The DF3E-2P-2H(51) is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications are required for substitution.
