Frequently Asked Questions (FAQ)

Q: Can DF33C-4DP-3.3DSA(24) be used as a direct replacement for DF33-4DP-3.3DSA(24)?

A: Yes. Both parts share identical mating pitch (3.3mm), position count (4), row configuration (2 rows), row spacing (5.80mm), voltage rating (500V), operating temperature range (-35°C to 85°C), and mounting specifications. No design modifications are required.

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

A: The primary differences are product status (obsolete vs. active), series designation (DF33 vs. DF33C), contact material (copper alloy vs. brass), insulation material composition, insulation color (natural vs. beige), packaging (unspecified vs. tray), and compliance certifications (RoHS vs. ROHS3). Electrical and mechanical performance remain equivalent.

Q: Are there any PCB layout considerations when switching from DF33-4DP-3.3DSA(24) to DF33C-4DP-3.3DSA(24)?

A: No. Both parts maintain identical through-hole mounting specifications, post length (3.00mm), insulation height (11.50mm), and mated stacking height (17.6mm). Existing PCB footprints and assembly processes remain unchanged.

Q: What is the packaging difference?

A: The DF33-4DP-3.3DSA(24) packaging is unspecified in available documentation. The DF33C-4DP-3.3DSA(24) is supplied in tray packaging. Confirm packaging requirements with your procurement specification.

Q: Are both parts RoHS compliant?

A: Yes. The DF33-4DP-3.3DSA(24) is RoHS compliant. The DF33C-4DP-3.3DSA(24) meets the more recent ROHS3 standard, providing enhanced regulatory compliance.
