DF3Z-8P-2V(51) Equivalent & Substitute Parts

Part Overview

The DF3Z-8P-2V(51) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications. This 8-position connector operates across a wide temperature range of -55°C to 105°C and features a 2.00mm pitch with gold-plated brass contacts rated for 3A current. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The DF3E-8P-2V(51) qualifies as a direct substitute for the DF3Z-8P-2V(51) based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both are header connectors with male pins, 8 positions, and 2.00mm pitch
• Mechanical Compatibility: Identical shrouding (4 wall), surface mount mounting type, and push-pull fastening
• Electrical Specifications: Both feature gold-plated brass contacts, polyamide/nylon insulation, and operate across -55°C to 105°C
• Compliance & Safety: Both are RoHS compliant, UL94 V-0 rated, and MSL 1
• Series Alignment: Both belong to the Hirose DF3 series, ensuring mechanical and electrical interchangeability

The primary distinction is product status: the DF3Z variant is discontinued, while the DF3E variant remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-8P-2V(51) is the appropriate substitute for the discontinued DF3Z-8P-2V(51). Both connectors maintain identical electrical and mechanical specifications within the Hirose DF3 series, ensuring direct interchangeability in board-to-board and cable applications.

Selection should be based on the following factors:

• Product Availability: The DF3E variant is currently active in production with 875 pieces in stock, whereas the DF3Z is discontinued
• Compliance Alignment: Both parts meet RoHS compliance and UL94 V-0 flammability requirements
• Packaging Consideration: The DF3E-8P-2V(51) is supplied in Tape & Reel (TR) packaging, which may differ from the original part's packaging specification
• Electrical Performance: Current rating specifications differ between the two variants; the DF3Z is rated at 3A, while the DF3E rating varies by wire gauge

Frequently Asked Questions (FAQ)

Q: Are the DF3Z-8P-2V(51) and DF3E-8P-2V(51) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 8-position configuration, 2.00mm pitch, 4-wall shrouding, surface mount mounting, and push-pull fastening. They are directly interchangeable in board-to-board and cable applications.

Q: What is the primary reason for substitution?

A: The DF3Z-8P-2V(51) is discontinued at DiGi Electronics. The DF3E-8P-2V(51) provides functional equivalence while remaining in active production.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DF3Z and DF3E variants are RoHS compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference in packaging between these two parts?

A: The DF3E-8P-2V(51) is supplied in Tape & Reel (TR) packaging. The original DF3Z packaging specification is not provided in the technical data.

Q: Are there differences in current rating between the two parts?

A: Yes. The DF3Z-8P-2V(51) is rated for 3A current, while the DF3E-8P-2V(51) current rating varies by wire gauge. Verify wire gauge specifications for your application to ensure adequate current capacity.

Q: Do both parts operate across the same temperature range?

A: Yes. Both connectors operate across -55°C to 105°C, ensuring thermal compatibility in equivalent applications.
