Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF33-10DP-3.3DSA(24) is determined by strict equivalence across the following critical parameters:

• Number of positions: 10
• Number of rows: 2
• Pitch - mating: 0.130" (3.30mm)
• Row spacing - mating: 0.228" (5.80mm)
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Through Hole
• Voltage rating: 500V
• Operating temperature range: -35°C ~ 85°C
• Shrouding: Shrouded - 4 Wall
• Fastening type: Locking Ramp

The DF33C-10DP-3.3DSA(24) meets all these criteria and qualifies as a direct substitute. Variations in contact material, insulation material color, and product status do not affect functional compatibility within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-10DP-3.3DSA(24) is the qualified substitute for the obsolete DF33-10DP-3.3DSA(24). Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility.

The DF33C variant offers the advantage of active product status, providing ongoing availability and manufacturer support. The DF33C-10DP-3.3DSA(24) carries ROHS3 compliance, representing current regulatory alignment. Both parts meet UL94 V-0 flammability requirements and operate across the same temperature range with equivalent voltage ratings.

Contact material differs between the two parts (Copper Alloy in the original versus Brass in the substitute); however, both materials maintain equivalent electrical performance within the specified 500V rating and operating temperature range. Insulation material composition and color variations do not affect functional compatibility for board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can the DF33C-10DP-3.3DSA(24) be used as a direct replacement for the DF33-10DP-3.3DSA(24)?

A: Yes. Both parts share identical pitch (3.3mm), position count (10), row configuration (2), voltage rating (500V), operating temperature range (-35°C ~ 85°C), and mechanical mounting specifications. The parts are functionally equivalent for board-to-cable/wire applications.

Q: What is the difference in contact material between these two parts?

A: The DF33-10DP-3.3DSA(24) uses Copper Alloy contacts, while the DF33C-10DP-3.3DSA(24) uses Brass contacts. Both materials provide equivalent electrical performance within the 500V rating and specified operating conditions.

Q: Does the packaging difference affect compatibility?

A: No. The original part has unspecified packaging, while the substitute is supplied in Tray packaging. Packaging affects logistics and handling only; it does not impact electrical or mechanical compatibility.

Q: Why is the original part obsolete?

A: The DF33-10DP-3.3DSA(24) is listed as obsolete by the manufacturer. The DF33C series represents the current active product line for this connector configuration.

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

A: The DF33-10DP-3.3DSA(24) is RoHS Compliant, while the DF33C-10DP-3.3DSA(24) is ROHS3 Compliant. Both meet current regulatory requirements. The DF33C variant also carries REACH Unaffected status.
