Key Parameters

Substitute Part Grouping Explanation

The DF3EA-9P-2V(21) qualifies as a direct substitute for the DF3DZ-9P-2V(21) based on the following critical parameters:

• Identical connector type, contact type, and number of positions (9)
• Matching pitch specification at 0.079" (2.00mm)
• Identical mounting type (Surface Mount) and shrouding configuration (Shrouded - 4 Wall)
• Matching fastening type (Push-Pull) and termination method (Solder)
• Identical insulation height at 0.232" (5.90mm)
• Matching contact material (Brass) and finish (Tin)
• Identical insulation material (Polyamide/Nylon) and flammability rating (UL94 V-0)
• Same MSL rating (1 - Unlimited)

The DF3EA-9P-2V(21) maintains full mechanical and electrical compatibility while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-9P-2V(21) is the appropriate selection for applications currently using or specifying the obsolete DF3DZ-9P-2V(21). The substitute part maintains identical mechanical and electrical specifications while offering:

• Active product status ensuring long-term availability and supply chain continuity
• Extended operating temperature range (-55°C to 105°C versus -30°C to 85°C), providing broader environmental compatibility
• RoHS compliance certification for regulatory adherence
• Tape & Reel packaging suitable for automated assembly processes

Both parts share identical UL94 V-0 flammability ratings, MSL classifications, and core connector specifications, ensuring direct functional equivalence in board-level applications.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-9P-2V(21) be used as a direct replacement for DF3DZ-9P-2V(21)?

A: Yes. Both connectors share identical pitch (2.00mm), position count (9), mounting type (Surface Mount), shrouding configuration (4-Wall), and contact specifications. Mechanical and electrical compatibility is maintained.

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

A: The DF3DZ-9P-2V(21) is obsolete, while the DF3EA-9P-2V(21) maintains active product status. The DF3EA variant also provides an extended operating temperature range (-55°C to 105°C) and RoHS compliance.
