Key Parameters

Substitute Part Grouping Explanation

The DF33C-5P-3.3DSA(24) qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Both parts maintain identical 5-position, single-row, 3.3mm pitch header architecture
• Electrical Specifications: Current rating (5A) and voltage rating (500V) are identical
• Mechanical Interface: Through-hole mounting, shrouded 4-wall design, and solder termination are preserved
• Environmental Performance: Operating temperature range (-35°C ~ 85°C) and UL94 V-0 flammability rating match
• Regulatory Compliance: Both parts are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity

The primary distinction is product status: DF33-5P-3.3DSA(24) is obsolete, while DF33C-5P-3.3DSA(24) is active. Material and finish specifications differ (Copper Alloy vs. Brass contact material; Polyamide vs. Polybutylene Terephthalate insulation), but these variations remain within acceptable substitution parameters for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-5P-3.3DSA(24) is the appropriate substitute for the obsolete DF33-5P-3.3DSA(24). Both connectors maintain identical electrical and mechanical specifications, ensuring functional compatibility in board-to-cable/wire applications requiring 5-position, 3.3mm pitch headers with through-hole mounting.

The DF33C variant is currently in active production status, providing assured supply chain availability and ongoing manufacturer support. Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for industrial and commercial applications.

Material composition differences (Copper Alloy vs. Brass contact material; Polyamide vs. Polybutylene Terephthalate insulation) do not affect substitution validity, as both configurations deliver equivalent electrical performance and environmental durability within the specified operating temperature range of -35°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can DF33C-5P-3.3DSA(24) be used as a direct replacement for DF33-5P-3.3DSA(24)?

A: Yes. Both connectors share identical pitch (3.3mm), position count (5), mounting method (through-hole), electrical ratings (5A, 500V), and operating temperature range (-35°C ~ 85°C). The DF33C variant is the active production equivalent.

Q: What is the primary reason to transition from DF33-5P-3.3DSA(24) to DF33C-5P-3.3DSA(24)?

A: The DF33-5P-3.3DSA(24) is obsolete. The DF33C-5P-3.3DSA(24) is the active production part from Hirose Electric, ensuring continued availability and manufacturer support.

Q: Are there differences in contact material between these parts?

A: Yes. DF33-5P-3.3DSA(24) uses Copper Alloy contacts, while DF33C-5P-3.3DSA(24) uses Brass contacts. Both materials are tin-finished and deliver equivalent electrical performance for this connector class.

Q: Do the insulation materials differ?

A: Yes. DF33-5P-3.3DSA(24) uses glass-filled Polyamide (PA/Nylon), while DF33C-5P-3.3DSA(24) uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range.

Q: Is packaging different between these parts?

A: Yes. DF33C-5P-3.3DSA(24) is supplied in Tray packaging, while DF33-5P-3.3DSA(24) packaging is not specified. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS compliant?

A: Yes. Both DF33-5P-3.3DSA(24) and DF33C-5P-3.3DSA(24) are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What are the electrical specifications for these connectors?

A: Both parts are rated for 5A current and 500V voltage, suitable for low to medium-power signal and power distribution applications in board-to-cable/wire configurations.
