Key Parameters

Substitute Part Grouping Explanation

The DF3EA-8P-2V(51) qualifies as a direct substitute based on the following critical parameters that determine functional interchangeability:

• Connector Type, Contact Type, and Position Count: Both parts are 8-position male pin headers
• Pitch and Mating Dimensions: Identical 0.079" (2.00mm) pitch ensures mechanical compatibility
• Mounting and Termination: Both use surface mount with solder termination
• Shrouding and Fastening: Identical 4-wall shrouding and push-pull fastening mechanism
• Insulation Specifications: Matching polyamide nylon material, UL94 V-0 rating, and beige color
• Contact Finish: Gold plating on mating surfaces
• MSL Rating: Both rated MSL 1 (Unlimited)

The DF3EA-8P-2V(51) represents the active production equivalent within the DF3 series, with enhanced specifications and current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-8P-2V(51) is the recommended substitute for the obsolete DF3DZ-8P-2V(51) based on the following factors:

Product Status: The DF3EA-8P-2V(51) maintains active production status with significantly higher inventory availability (3800 pcs vs. 733 pcs), ensuring long-term supply chain reliability.

Compliance and Certifications: The DF3EA-8P-2V(51) carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in most markets.

Mechanical and Electrical Compatibility: All critical parameters determining functional interchangeability are identical, including connector geometry, pitch, shrouding, termination method, and contact configuration.

Enhanced Specifications: The substitute part offers an extended operating temperature range (-55°C ~ 105°C vs. -30°C ~ 85°C) and specified voltage rating (250VAC), providing greater design flexibility for demanding applications.

Contact Material Difference: The DF3EA-8P-2V(51) uses brass contacts versus phosphor bronze in the original part. Both materials with gold plating provide equivalent electrical performance and corrosion resistance for this connector class.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-8P-2V(51) and DF3EA-8P-2V(51) mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), shrouding configuration (4-wall), insulation height (0.232" / 5.90mm), and contact geometry. They are directly interchangeable in board-to-board or cable applications without modification to PCB layouts or mating connectors.

Q: What is the difference in contact material, and does it affect performance?

A: The DF3DZ-8P-2V(51) uses phosphor bronze contacts, while the DF3EA-8P-2V(51) uses brass contacts. Both materials are plated with gold for mating surfaces. For this connector class and typical signal/power applications, both materials provide equivalent electrical conductivity, corrosion resistance, and reliability.

Q: Can I use DF3EA-8P-2V(51) in applications designed for DF3DZ-8P-2V(51)?

A: Yes. The substitute part meets or exceeds the original specifications. The extended operating temperature range (-55°C ~ 105°C) and specified voltage rating (250VAC) make it suitable for all applications within the original part's operating envelope.

Q: What packaging is available for the DF3EA-8P-2V(51)?

A: The DF3EA-8P-2V(51) is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly. The original DF3DZ-8P-2V(51) packaging specification was not provided.

Q: Are there any compliance differences between these parts?

A: The DF3EA-8P-2V(51) carries ROHS3 compliance and REACH unaffected status. Both parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The substitute part meets current regulatory requirements for most markets.

Q: What are the mated stacking heights for the DF3EA-8P-2V(51)?

A: The DF3EA-8P-2V(51) supports mated stacking heights of 7.5mm, 7.7mm, and 8.4mm, providing flexibility for multi-connector board designs.
