DF3DZ-11P-2H(21) Equivalent & Substitute Parts

Part Overview

The DF3DZ-11P-2H(21) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle board-to-board or cable applications. This 11-position connector operates at 0.079" (2.00mm) pitch with a 3A current rating and operates across -55°C to 105°C. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3DZ-11P-2H(21) is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 11
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder

Two substitute parts meet these core electrical and mechanical requirements:

1. DF3EA-11P-2H(21) - Direct Hirose Electric equivalent within the DF3 series, maintaining identical pitch, position count, and mounting configuration with active product status.

2. S11B-PH-SM4-TB - JST Sales America alternative meeting core dimensional and electrical specifications, though with operational parameter variations requiring evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

DF3EA-11P-2H(21) is the primary substitute for the DF3DZ-11P-2H(21). Both connectors are manufactured by Hirose Electric within the DF3 series and maintain identical electrical and mechanical specifications. The DF3EA-11P-2H(21) carries active product status with RoHS compliance and UL94 V-0 flammability rating. This part provides direct functional equivalence with the added feature of solder retention and is available in Tape & Reel packaging.

S11B-PH-SM4-TB serves as an alternative substitute from JST Sales America. While this connector meets the core dimensional requirements (11 positions, 0.079" pitch, surface mount right-angle configuration), it operates within a reduced temperature range (-25°C to 85°C versus -55°C to 105°C) and carries a lower current rating (2A versus 3A). The S11B-PH-SM4-TB features a detent lock fastening mechanism and square contact geometry, differing from the push-pull fastening and circular contacts of the original part. This substitute is suitable for applications within its specified operating parameters and offers the highest inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-11P-2H(21) be used as a direct replacement for DF3DZ-11P-2H(21)?

A: Yes. Both connectors share identical pitch (0.079"), position count (11), row configuration (1), mounting type (surface mount right-angle), shrouding (4-wall), and termination method (solder). Both operate across -55°C to 105°C and carry UL94 V-0 flammability rating. The DF3EA-11P-2H(21) is the recommended substitute due to active product status and direct series compatibility.

Q: What are the limitations of S11B-PH-SM4-TB as a substitute?

A: The S11B-PH-SM4-TB operates within a narrower temperature range (-25°C to 85°C) and carries a lower current rating (2A). Applications requiring the full -55°C to 105°C operating range or 3A current capacity must use DF3EA-11P-2H(21). Additionally, the S11B-PH-SM4-TB uses detent lock fastening rather than push-pull, requiring mechanical interface verification.

Q: Are all three connectors RoHS compliant?

A: Yes. DF3DZ-11P-2H(21) and DF3EA-11P-2H(21) are RoHS Compliant. S11B-PH-SM4-TB is ROHS3 Compliant. All three meet RoHS requirements for lead-free construction.

Q: What packaging options are available for substitute parts?

A: DF3EA-11P-2H(21) is supplied in Tape & Reel (TR) packaging. S11B-PH-SM4-TB is also supplied in Tape & Reel (TR) packaging. Original DF3DZ-11P-2H(21) packaging is not specified in available data.

Q: How do contact geometry differences affect compatibility?

A: DF3DZ-11P-2H(21) and DF3EA-11P-2H(21) both use circular brass contacts. S11B-PH-SM4-TB uses square copper alloy contacts. Contact geometry differences may affect mating force and connector durability characteristics. Mechanical interface compatibility with mating connectors must be verified before substitution.

Q: What is the moisture sensitivity level for these connectors?

A: All three connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
