Engineering Selection Recommendations

The DF33C-2P-3.3DSA(24) is the direct active equivalent for the DF33-2P-3.3DSA(24). Both connectors maintain identical electrical performance specifications, mechanical dimensions, and thermal operating ranges. The DF33C variant represents the current production continuation of the EnerBee™ DF33 series and carries Active product status, ensuring long-term availability and supply chain continuity.

Material composition differences exist between the two parts: the original uses Copper Alloy contacts with glass-filled Polyamide insulation, while the substitute uses Brass contacts with Polybutylene Terephthalate insulation. Both configurations meet UL94 V-0 flammability requirements and maintain identical electrical ratings. The DF33C-2P-3.3DSA(24) achieves ROHS3 compliance, providing enhanced regulatory alignment for new designs.

For applications requiring component replacement or new procurement, the DF33C-2P-3.3DSA(24) provides full functional and mechanical compatibility with identical pin configuration, pitch spacing, and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can the DF33C-2P-3.3DSA(24) be used as a direct replacement for the DF33-2P-3.3DSA(24)?

A: Yes. Both connectors share identical electrical ratings (5A, 500V), mechanical dimensions (2 positions, 3.30mm pitch, 17.6mm stacking height), operating temperature range (-35°C ~ 85°C), and through-hole solder termination. Pin-to-pin compatibility is complete.

Q: What are the material differences between these two parts?

A: The DF33-2P-3.3DSA(24) uses Copper Alloy contacts with glass-filled Polyamide insulation. The DF33C-2P-3.3DSA(24) uses Brass contacts with Polybutylene Terephthalate insulation. Both materials maintain equivalent electrical performance and UL94 V-0 flammability ratings.

Q: Why is the original part listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. The DF33C-2P-3.3DSA(24) represents the active production equivalent within the same EnerBee™ DF33 connector family.

Q: Are there any compliance differences between the two parts?

A: The DF33-2P-3.3DSA(24) is RoHS Compliant. The DF33C-2P-3.3DSA(24) is ROHS3 Compliant, representing an updated regulatory certification. Both parts carry Moisture Sensitivity Level 1 (Unlimited).

Q: Will the PCB footprint remain the same if I switch to the substitute part?

A: Yes. Both connectors maintain identical through-hole mounting specifications, insulation height (11.50mm), and mated stacking height (17.6mm). PCB layout and footprint design require no modification.

Q: What is the current inventory status for each part?

A: The DF33-2P-3.3DSA(24) has 1144 pieces in stock. The DF33C-2P-3.3DSA(24) has 970 pieces in stock. Both are available as new original components.
