DF3Z-9P-2V(20) Equivalent & Substitute Parts

Part Overview

The DF3Z-9P-2V(20) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with 9 positions at 2.00mm pitch. This connector features shrouded 4-wall construction, solder termination, and push-pull fastening for board-to-board or cable connections. 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-9P-2V(20) is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 9 positions at 0.079" (2.00mm) mating pitch
• Mounting Technology: Surface mount construction
• Shrouding Design: Shrouded 4-wall configuration
• Termination Method: Solder termination
• Current Capacity: 3A minimum rating
• Material Compliance: UL94 V-0 flammability rating
• Contact Material & Finish: Brass with tin plating

The substitute part 1775470-9 from TE Connectivity AMP Connectors meets these core substitution criteria. Both parts share identical position count, pitch, mounting type, shrouding, termination method, current rating, and flammability compliance. Variations in operating temperature range, insulation material composition, and contact geometry do not preclude functional substitution when application requirements fall within the substitute's specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The 1775470-9 from TE Connectivity AMP Connectors is an active product suitable for replacing the obsolete DF3Z-9P-2V(20). Both parts comply with UL94 V-0 flammability requirements and share identical electrical and mechanical substitution criteria: 9-position, 2.00mm pitch, surface mount, shrouded 4-wall header with 3A current rating and solder termination.

Design considerations for substitution:

• Operating Temperature: The substitute operates within -25°C to 85°C. Applications requiring the original part's extended lower temperature range (-55°C) require thermal validation.
• Insulation Material: The substitute uses PA9T nylon composition versus the original PA nylon. Both materials meet UL94 V-0 compliance.
• Contact Geometry: The substitute features square contacts with 0.138" (3.50mm) mating length and increased tin plating thickness (80.0µin versus 39.4µin). These differences do not affect functional compatibility for standard board-to-cable applications.
• Packaging: The substitute is supplied in Tape & Reel format, supporting automated assembly processes.
• Availability: The substitute maintains active production status with documented inventory, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1775470-9 directly replace the DF3Z-9P-2V(20) in existing designs?

A: Yes, for applications operating within -25°C to 85°C. Both connectors share identical position count (9), pitch (2.00mm), mounting type (surface mount), shrouding (4-wall), termination (solder), and current rating (3A). Designs requiring operation below -25°C require thermal analysis to confirm the substitute's suitability.

Q: What are the key differences between these two connectors?

A: Primary differences include operating temperature range, contact shape (circular versus square), contact finish thickness, and insulation material composition. The substitute provides higher tin plating thickness and uses advanced PA9T nylon insulation. These differences do not affect electrical or mechanical compatibility for standard applications.

Q: Are both connectors RoHS compliant?

A: The DF3Z-9P-2V(20) compliance status is not specified in available documentation. The 1775470-9 is ROHS3 compliant, meeting current regulatory requirements for electronic components.

Q: What is the impact of different contact shapes (circular versus square)?

A: Contact shape does not affect mating compatibility or electrical performance. Both circular and square contact geometries provide equivalent contact pressure and current-carrying capacity at the specified 3A rating.

Q: Does the substitute support the same packaging and assembly methods?

A: The substitute is supplied in Tape & Reel (TR) packaging, optimized for automated surface mount assembly. The original part packaging is not specified. Both support standard solder reflow processes.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and EAR99 export classification. The substitute includes ROHS3 compliance documentation. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.
