DF11Z-20DP-2V(21) Equivalent & Substitute Parts

Part Overview

The DF11Z-20DP-2V(21) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd, featuring 20 positions arranged in 2 rows with 2.00mm pitch. This connector is designed for board-to-board or cable applications with solder termination and detent lock fastening. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11Z-20DP-2V(21) is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (20 positions, 2 rows)
• Pitch specifications (0.079" / 2.00mm mating pitch and row spacing)
• Mounting technology (Surface Mount)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Electrical ratings (2A current, 250V voltage)
• Operating temperature range (-30°C ~ 85°C)
• Flammability compliance (UL94 V-0)
• RoHS compliance status

The DF11CZ-20DP-2V(27) meets all these criteria and is classified as an active product within the same DF11 series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The DF11CZ-20DP-2V(27) is the appropriate substitute for the obsolete DF11Z-20DP-2V(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, current and voltage ratings, and operating temperature range. The substitute part carries active product status with ROHS3 compliance, providing improved regulatory alignment compared to the original RoHS Compliant designation. The packaging format change from unspecified to Tape & Reel (TR) supports automated assembly processes. The insulation color difference (Natural to Beige) and feature variation (Board Guide to Pick and Place) do not affect functional compatibility in board-to-board or cable connection applications.

Frequently Asked Questions (FAQ)

Q: Are the DF11Z-20DP-2V(21) and DF11CZ-20DP-2V(27) mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (2.00mm), row spacing (2.00mm), position count (20 in 2 rows), insulation height (7.19mm), and mounting type (surface mount). They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete versus active), packaging format (unspecified versus Tape & Reel), insulation color (Natural versus Beige), and assembly features (Board Guide versus Pick and Place). Electrical and mechanical performance are identical.

Q: Does the packaging change affect circuit board design?

A: No. The Tape & Reel packaging of the DF11CZ-20DP-2V(27) is a supply format change that does not alter the connector's physical dimensions, footprint, or electrical characteristics on the circuit board.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 2A current and 250V voltage with identical operating temperature range (-30°C ~ 85°C) and flammability compliance (UL94 V-0).

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 Compliant status on the DF11CZ-20DP-2V(27) indicates compliance with the latest Restriction of Hazardous Substances directive, providing enhanced regulatory alignment for new designs and procurement cycles.

Q: Can the DF11CZ-20DP-2V(27) be used in existing designs specified for DF11Z-20DP-2V(21)?

A: Yes. The substitute part meets all functional and electrical requirements of the original specification. No circuit board redesign is required.
