Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2V(51) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Series Compatibility: Both parts belong to the Hirose DF3 series, ensuring mechanical and electrical interchangeability
• Connector Configuration: Identical 4-position header with male pin contact type
• Pitch Specification: Both maintain 0.079" (2.00mm) mating pitch
• Mounting Method: Both are surface mount with identical shrouded 4-wall design
• Fastening Mechanism: Both use push-pull fastening
• Electrical Characteristics: Both support the required operating temperature range of -55°C ~ 105°C and UL94 V-0 flammability rating
• Environmental Compliance: Both are RoHS compliant with MSL 1 rating

The primary distinction is product status: DF3Z-4P-2V(51) is discontinued, while DF3E-4P-2V(51) is active with superior inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2V(51) is the appropriate substitute for the discontinued DF3Z-4P-2V(51). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The DF3E variant offers the following advantages:

• Active Product Status: DF3E-4P-2V(51) is currently in active production, ensuring long-term availability and supply chain stability
• Enhanced Compliance: ROHS3 compliance provides alignment with current regulatory requirements
• Superior Inventory: 2847 units in stock compared to 881 units of the discontinued variant
• Standardized Packaging: Tape & Reel packaging supports automated assembly processes

Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Are DF3Z-4P-2V(51) and DF3E-4P-2V(51) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (4), shrouding configuration (4-wall), and mounting method (surface mount). They are fully interchangeable in board-level applications.

Q: What is the difference between the DF3Z and DF3E variants?

A: The primary difference is product lifecycle status. DF3Z is discontinued, while DF3E is active. Both maintain identical electrical ratings, operating temperature range (-55°C ~ 105°C), and material specifications (UL94 V-0, RoHS compliant).

Q: Does the packaging difference affect compatibility?

A: No. The DF3E-4P-2V(51) is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components and supports automated pick-and-place assembly. The connector itself is identical regardless of packaging format.

Q: Are there any current rating differences?

A: The DF3Z-4P-2V(51) specifies 3A current rating. The DF3E-4P-2V(51) current rating varies by wire gauge. For standard applications using the same wire gauge as the original design, current handling capacity remains equivalent.

Q: Can I use DF3E-4P-2V(51) in existing designs without PCB modification?

A: Yes. Identical mechanical dimensions, pitch, and mounting specifications ensure direct substitution without PCB redesign or layout changes.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant, UL94 V-0 rated, MSL 1 (unlimited moisture sensitivity), and classified as EAR99 for export purposes. The DF3E variant carries ROHS3 compliance, representing current regulatory alignment.
