Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF33-4DS-3.3C is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle housing
• Contact type: Female socket
• Number of positions: 4
• Pitch specification: 0.130" (3.30mm)
• Row configuration: 2 rows with 0.228" (5.80mm) spacing
• Mounting method: Free hanging in-line
• Contact termination: Crimp
• Fastening mechanism: Latch lock

The DF33C-4DS-3.3C meets all these criteria and is classified as a direct substitute. This part maintains identical electrical and mechanical interface specifications while offering improved product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-4DS-3.3C is the direct substitute for the obsolete DF33-4DS-3.3C. Both parts maintain identical electrical and mechanical specifications across all critical interface parameters. The substitute part offers the following advantages:

• Active product status with established supply chain availability
• ROHS3 compliance, meeting current regulatory requirements
• Equivalent RoHS compliance and MSL rating
• Identical connector interface specifications ensuring mechanical and electrical compatibility

The color difference (natural versus white) is a cosmetic variation that does not affect functional performance or electrical characteristics. Both parts carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the DF33C-4DS-3.3C be used as a direct replacement for the DF33-4DS-3.3C?

A: Yes. The DF33C-4DS-3.3C is a direct substitute. Both parts share identical specifications for connector type, contact configuration, pitch, row spacing, mounting method, termination type, and fastening mechanism. The parts are mechanically and electrically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and color. The DF33-4DS-3.3C is obsolete, while the DF33C-4DS-3.3C is active. The DF33-4DS-3.3C has a natural color housing, while the DF33C-4DS-3.3C has a white housing. Both parts meet RoHS compliance requirements and carry identical electrical specifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The parts are designed to interface with identical mating connectors and contact configurations. The MSL rating of 1 (Unlimited) is equivalent for both parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the packaging difference?

A: The DF33-4DS-3.3C is listed with no specified packaging information, while the DF33C-4DS-3.3C is supplied in bulk packaging. This difference affects ordering and inventory management but does not impact the functional characteristics of the connector housing.

Q: Do these parts require specific contact types?

A: Both parts are receptacle housings designed for female socket contacts. Contacts are not included with either part and must be sourced separately. The crimp termination specification applies to both parts.
