DF3Z-8P-2H(50) Equivalent & Substitute Parts

Part Overview

The DF3Z-8P-2H(50) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle board-to-board or cable applications with 8 positions at 2.00mm pitch. This connector features shrouded 4-wall construction with solder termination and push-pull fastening. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3Z-8P-2H(50) is based on the following critical parameters that must align for functional compatibility:

• Connector Type & Contact Type: Header with male pins
• Position Count & Pitch: 8 positions at 0.079" (2.00mm) mating pitch
• Mounting Configuration: Surface mount, right-angle orientation
• Shrouding: Shrouded 4-wall design
• Termination Method: Solder termination
• Current Rating: 3A minimum
• Insulation Material: Polyamide or Nylon-based
• Contact Material: Brass construction
• Flammability Compliance: UL94 V-0

The substitute part 1775469-8 from TE Connectivity AMP Connectors meets these core functional requirements. Variations in contact finish (gold vs. tin), operating temperature range, and voltage rating do not preclude substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 1775469-8 from TE Connectivity AMP Connectors is a direct functional substitute for the obsolete DF3Z-8P-2H(50). Both connectors share identical core specifications: 8-position, 2.00mm pitch, surface-mount right-angle headers with shrouded 4-wall construction and 3A current rating.

The substitute part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity rating (MSL 1).

Design considerations for substitution:

• The TE Connectivity part operates within -25°C ~ 85°C, which is narrower than the Hirose original (-55°C ~ 105°C). Verify that application temperature requirements fall within the substitute's operating range.
• Contact finish differs (tin vs. gold). Tin plating is suitable for standard solder applications and provides cost efficiency without compromising electrical performance in non-corrosive environments.
• The substitute includes a specified voltage rating of 250V, providing additional electrical specification clarity for design documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1775469-8 be used as a direct replacement for the DF3Z-8P-2H(50)?

A: Yes, the 1775469-8 is functionally equivalent for applications within its operating temperature range (-25°C ~ 85°C). Both connectors share identical pitch, position count, mounting type, shrouding, and current rating specifications.

Q: What is the difference between gold and tin contact finishes?

A: Gold plating provides superior corrosion resistance and is preferred in high-reliability or harsh environments. Tin plating is suitable for standard solder applications and is cost-effective for general-purpose and industrial use. Both finishes are electrically compatible for this connector category.

Q: Are there packaging differences between these parts?

A: The DF3Z-8P-2H(50) packaging is not specified in available data. The 1775469-8 is supplied in Tape & Reel (TR) format, which is standard for surface-mount components and facilitates automated assembly.

Q: Does the narrower operating temperature range of the substitute affect compatibility?

A: The substitute operates from -25°C ~ 85°C, compared to the original's -55°C ~ 105°C range. Substitution is valid only if your application operates within the substitute's temperature limits. Verify application requirements before selection.

Q: Are both parts RoHS compliant?

A: The DF3Z-8P-2H(50) RoHS status is not specified. The 1775469-8 is ROHS3 compliant, meeting current environmental regulations for new designs and production.

Q: What is the significance of MSL 1 (Unlimited) rating?

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