Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3EA-7P-2V(20) is determined by strict equivalence across the following critical parameters:

• Connector series and base product number (DF3EA)
• Number of positions (7)
• Pitch spacing (0.079" / 2.00mm)
• Connector type (Header)
• Contact type (Male Pin)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Termination method (Solder)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (250VAC)
• Material flammability rating (UL94 V-0)

The DF3EA-7P-2V(24) qualifies as a direct substitute based on identical electrical and mechanical specifications within these parameters. Differences in packaging format and insulation color do not affect functional compatibility in applications requiring the DF3 series 7-position 2.00mm pitch header.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-7P-2V(24) serves as the direct functional equivalent for the obsolete DF3EA-7P-2V(20). Both parts maintain identical electrical and mechanical specifications across all critical parameters governing connector interchangeability.

The DF3EA-7P-2V(24) carries Last Time Buy status, indicating limited future availability. The part is RoHS Compliant, providing enhanced environmental compliance compared to the original part specification. Packaging is supplied in Tube format.

Insulation color differs between the two parts (Beige versus Black); this distinction is cosmetic and does not affect electrical or mechanical performance in applications where color coding is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-7P-2V(24) be used as a direct replacement for DF3EA-7P-2V(20)?

A: Yes. Both parts are identical in all electrical and mechanical parameters that determine connector functionality, including pitch spacing, number of positions, contact configuration, operating temperature range, voltage rating, and mounting specifications.

Q: What is the significance of the different insulation colors?

A: Insulation color (Beige in the original, Black in the substitute) is a cosmetic distinction that does not affect electrical performance or mechanical compatibility. Selection should be based on application requirements for color identification or marking.

Q: Does the RoHS Compliance status of DF3EA-7P-2V(24) affect compatibility?

A: No. RoHS Compliance is an environmental and regulatory attribute that does not alter the connector's electrical or mechanical function. It represents an enhancement in environmental compliance.

Q: Are there differences in mated stacking heights between the two parts?

A: The DF3EA-7P-2V(20) specifies multiple mated stacking heights (7.5mm, 7.7mm, 8.4mm), while DF3EA-7P-2V(24) specifies 8.4mm. Both parts support the 8.4mm stacking height, ensuring compatibility in standard applications.

Q: What is the impact of Last Time Buy status on the substitute part?

A: Last Time Buy status indicates that DF3EA-7P-2V(24) has limited future availability. Procurement planning should account for this status when establishing long-term supply strategies.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tube for the substitute) is a logistics and handling consideration that does not affect the connector's electrical or mechanical specifications or performance in the application.
