Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3EA-4P-2H(50) is determined by strict equivalence across the following critical parameters:

• Series designation (DF3)
• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Mating pitch (2.00mm)
• Mounting configuration (Surface Mount, Right Angle)
• Shrouding style (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability compliance (UL94 V-0)

The DF3EA-4P-2H(54) qualifies as a direct substitute based on full alignment with these parameters. Variations in packaging format, insulation color, and product status do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-4P-2H(54) is a direct functional equivalent to the DF3EA-4P-2H(50) for all circuit and mechanical applications. Selection between these parts should be based on the following factors:

Product Status Consideration: The DF3EA-4P-2H(50) is obsolete, while the DF3EA-4P-2H(54) carries Last Time Buy status, indicating extended availability. For new designs or ongoing production, the DF3EA-4P-2H(54) is the preferred choice.

Compliance and Certification: Both parts meet UL94 V-0 flammability requirements and carry identical electrical ratings. The DF3EA-4P-2H(54) is explicitly RoHS Compliant, which may be required for certain regulatory jurisdictions or customer specifications.

Packaging and Logistics: The DF3EA-4P-2H(54) is supplied in Tube packaging, which may affect inventory management and assembly line integration compared to the unspecified packaging of the DF3EA-4P-2H(50).

Physical Appearance: Insulation color differs between the two parts (Beige versus Black). This variation does not affect electrical performance but may impact visual identification in assembly or maintenance contexts.

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-4P-2H(54) be used as a direct replacement for the DF3EA-4P-2H(50) in existing designs?

A: Yes. The DF3EA-4P-2H(54) is functionally equivalent across all critical electrical and mechanical parameters, including connector type, contact configuration, pitch, voltage rating, temperature range, and flammability compliance. No circuit redesign is required.

Q: What is the significance of the different product status designations?

A: The DF3EA-4P-2H(50) is classified as Obsolete, indicating it is no longer manufactured and existing inventory is depleted. The DF3EA-4P-2H(54) is Last Time Buy status, meaning production will cease but inventory remains available for a defined period. For production continuity, the DF3EA-4P-2H(54) should be selected.

Q: Does the insulation color difference affect connector performance?

A: No. Insulation color is a cosmetic variation that does not impact electrical characteristics, mechanical fit, or thermal performance. Selection between Beige and Black insulation should be based on assembly identification requirements or customer specifications.

Q: Why does the DF3EA-4P-2H(54) specify RoHS Compliance while the DF3EA-4P-2H(50) does not?

A: RoHS Compliance documentation may reflect manufacturing date or regulatory documentation practices. Both parts are from the same DF3 series and share identical material specifications. If RoHS certification is a requirement, the DF3EA-4P-2H(54) provides explicit compliance documentation.

Q: Are there any packaging considerations when switching from DF3EA-4P-2H(50) to DF3EA-4P-2H(54)?

A: The DF3EA-4P-2H(54) is supplied in Tube packaging. Verify that your assembly equipment and inventory management systems are compatible with tube packaging formats. This may require adjustment to feeder configurations or component handling procedures.

Q: Do both parts meet the same electrical and thermal specifications?

A: Yes. Both parts are rated for 250VAC operation, support the same -55°C to 105°C operating temperature range, and feature identical contact materials, finishes, and solder retention features. Electrical performance is equivalent.
