DF3DZ-6P-2H(21) Equivalent & Substitute Parts

Part Overview

The DF3DZ-6P-2H(21) is a surface mount, right-angle rectangular connector header manufactured by Hirose Electric Co Ltd. This 6-position connector operates at 3A current rating with a 2.00mm pitch and is designed for board-to-board or cable applications. The part is discontinued at DiGi Electronics, making identification of equivalent alternatives essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

The DF3EA-6P-2H(21) qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Both parts are male pin headers with identical 6-position, single-row configuration
• Pitch & Mating Dimensions: Both maintain 0.079" (2.00mm) pitch spacing, ensuring mechanical compatibility with mating connectors
• Mounting & Orientation: Both are surface mount, right-angle designs with shrouded 4-wall construction
• Electrical Ratings: Both support 3A current rating and operate across -55°C ~ 105°C temperature range
• Compliance & Safety: Both are RoHS compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity
• Termination Method: Both use solder termination with push-pull fastening

The primary distinction is product status: DF3DZ-6P-2H(21) is discontinued, while DF3EA-6P-2H(21) remains active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-6P-2H(21) is the appropriate substitute for the discontinued DF3DZ-6P-2H(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The DF3EA-6P-2H(21) offers the additional advantage of active product status with significantly higher inventory availability (2,896 pcs vs. 932 pcs), ensuring supply chain continuity. Both parts carry RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications. The DF3EA-6P-2H(21) includes solder retention features and is supplied in Tape & Reel packaging, which may provide cost and handling benefits for production environments.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-6P-2H(21) and DF3EA-6P-2H(21) mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (2.00mm), position count (6), mounting orientation (surface mount right-angle), and shrouding configuration (4-wall). They are mechanically interchangeable without PCB redesign.

Q: Do these parts have the same electrical ratings?

A: Both parts operate at -55°C ~ 105°C and support 3A current rating. They use identical contact materials (brass with tin finish) and insulation materials (polyamide/nylon). Electrical performance is equivalent.

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

A: The primary difference is product lifecycle status. DF3DZ-6P-2H(21) is discontinued, while DF3EA-6P-2H(21) is active. The DF3EA variant includes solder retention features and is packaged in Tape & Reel format. Both are from the same DF3 series by Hirose Electric.

Q: Are there any compliance differences?

A: No. Both parts are RoHS compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. Regulatory compliance is identical.

Q: Can I use DF3EA-6P-2H(21) in existing designs specified for DF3DZ-6P-2H(21)?

A: Yes. The DF3EA-6P-2H(21) is a direct functional equivalent with no design modifications required. It maintains all critical electrical and mechanical parameters.

Q: What packaging format is available for the substitute part?

A: The DF3EA-6P-2H(21) is supplied in Tape & Reel (TR) packaging, which is standard for production environments and automated assembly processes.
