Key Parameters

Substitute Part Grouping Explanation

The DF3EA-11P-2V(21) qualifies as a direct substitute based on the following critical parameters:

• Identical connector type, contact type, and position count (11-position header, male pin)
• Matching pitch specification (0.079" / 2.00mm)
• Identical mounting method (surface mount) and shrouding configuration (shrouded 4-wall)
• Matching fastening type (push-pull)
• Identical insulation height (0.232" / 5.90mm)
• Identical contact material (brass) and finish (tin)
• Identical insulation material (polyamide/nylon) and flammability rating (UL94 V-0)
• Matching MSL rating (1 - Unlimited)

The substitute part maintains full mechanical and electrical compatibility while offering enhanced operating temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-11P-2V(21) is the appropriate selection for applications currently using or specifying the obsolete DF3DZ-11P-2V(21). The substitute part maintains identical mechanical and electrical specifications while providing:

• 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), supporting broader environmental applications
• RoHS compliance certification
• Tape & Reel packaging suitable for automated assembly processes

Direct pin-to-pin and footprint compatibility is maintained. No circuit redesign or PCB layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-11P-2V(21) and DF3EA-11P-2V(21) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (11), mounting type (surface mount), shrouding configuration (4-wall), and insulation height (5.90mm). PCB footprints are identical.

Q: What is the primary difference between these parts?

A: The DF3EA-11P-2V(21) is an active product with extended operating temperature range (-55°C to 105°C) and RoHS compliance, while the DF3DZ-11P-2V(21) is obsolete with a narrower temperature range (-30°C to 85°C).

Q: Can I use DF3EA-11P-2V(21) in existing designs specified for DF3DZ-11P-2V(21)?

A: Yes. The substitute part is fully compatible. No design changes are required.

Q: Does packaging differ between these parts?

A: Yes. The DF3DZ-11P-2V(21) is supplied in bulk packaging, while the DF3EA-11P-2V(21) is supplied in Tape & Reel (TR) format, which is standard for automated assembly.

Q: Are there any electrical rating differences?

A: The DF3EA-11P-2V(21) specifies current rating as "Varies by Wire Gauge" and includes a 250VAC voltage rating, while the DF3DZ-11P-2V(21) specifies 3A current rating. Both parts maintain identical contact material (brass) and finish (tin).

Q: Is RoHS compliance a factor in substitution?

A: The DF3EA-11P-2V(21) is RoHS compliant, which may be required for certain applications or markets. The DF3DZ-11P-2V(21) RoHS status is not specified.
