Key Parameters

Substitute Part Grouping Explanation

The DF33C-4P-3.3DSA(24) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical connector type (Header) and contact type (Male Pin)
• Matching number of positions (4) and mating pitch (0.130" / 3.30mm)
• Identical mounting method (Through Hole) and termination (Solder)
• Matching electrical ratings: 5A current and 500V voltage
• Identical operating temperature range (-35°C ~ 85°C)
• Equivalent shrouding configuration (Shrouded - 4 Wall)
• Matching fastening type (Locking Ramp) and board guide feature
• Identical mated stacking height (17.6mm)

The substitute part is from the active EnerBee™ DF33C series, providing continuity within the same connector family while maintaining all functional and electrical parameters required for direct replacement.

Engineering Selection Recommendations

The DF33C-4P-3.3DSA(24) is the appropriate substitute for the obsolete DF33-4P-3.3DSA(24). Selection is based on the following factors:

Product Status: The substitute part is active and currently in production, ensuring long-term availability and supply chain continuity. The original part is obsolete, making the substitute necessary for new designs and ongoing production support.

Compliance and Certifications: Both parts maintain identical compliance profiles with UL94 V-0 flammability rating and equivalent RoHS status. The substitute achieves ROHS3 compliance, representing current regulatory alignment. Both parts carry EAR99 export classification and identical HTSUS codes, confirming regulatory equivalence.

Electrical and Mechanical Compatibility: All critical functional parameters are identical, including connector geometry, pitch, contact configuration, electrical ratings, and operating temperature range. The substitute maintains the same through-hole mounting footprint and mated stacking height, enabling direct PCB-level replacement without design modification.

Material Differences: The substitute uses Brass contacts and PBT insulation material in place of Copper Alloy contacts and glass-filled Polyamide insulation. These material changes represent standard evolution within the EnerBee™ connector family and do not affect electrical performance or mechanical compatibility for the specified application parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical connector type, contact configuration, pitch, electrical ratings, operating temperature range, and mounting method. The substitute is functionally equivalent and requires no design changes.

Q: What is the difference between the contact materials?

A: The original part uses Copper Alloy contacts, while the substitute uses Brass contacts. Both materials provide equivalent electrical conductivity and contact performance for the 5A current rating and 500V voltage specification.

Q: Are the insulation materials interchangeable?

A: Yes. The original part uses glass-filled Polyamide insulation, while the substitute uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and maintain identical electrical insulation properties for this application.

Q: Does packaging differ between these parts?

A: The original part packaging is not specified. The substitute is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any compliance differences?

A: Both parts are RoHS compliant. The substitute achieves ROHS3 compliance, representing current regulatory standards. The substitute also carries REACH Unaffected status. Both parts maintain identical ECCN and HTSUS classifications.

Q: What is the inventory status?

A: The original part has 949 pieces in stock. The substitute has 1070 pieces in stock. The substitute's active product status ensures ongoing availability.

Q: Will the PCB footprint remain the same?

A: Yes. Both parts maintain identical through-hole mounting specifications, insulation height (0.453" / 11.50mm), contact post length (0.118" / 3.00mm), and mated stacking height (17.6mm). No PCB redesign is required.
