Key Parameters

Substitute Part Grouping Explanation

The DF33C-3S-3.3C qualifies as a direct substitute for the DF33-3S-3.3C based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both are receptacle housings with female socket contacts
• Position Count & Pitch: Both feature 3 positions at 0.130" (3.30mm) pitch
• Mounting & Termination: Both use free-hanging in-line mounting with crimp termination and latch lock fastening
• Row Configuration: Both are single-row designs
• Compliance Standards: Both meet RoHS requirements and have MSL rating of 1 (Unlimited)

The primary difference is product status: DF33C-3S-3.3C is active production, while DF33-3S-3.3C is obsolete. The DF33C variant also includes specified operating temperature range and insulation material documentation.

Parameter Comparison

Engineering Selection Recommendations

The DF33C-3S-3.3C is the appropriate substitute for the obsolete DF33-3S-3.3C. Selection is based on:

• Functional Equivalence: All critical electrical and mechanical parameters match, ensuring direct compatibility in existing applications
• Active Production Status: DF33C-3S-3.3C is in active production, providing reliable long-term availability and supply chain continuity
• Enhanced Compliance: DF33C-3S-3.3C meets ROHS3 compliance, representing current regulatory standards
• Documented Specifications: DF33C-3S-3.3C includes specified operating temperature range (-35°C ~ 85°C) and insulation material (PBT), providing complete technical documentation for design verification

Frequently Asked Questions (FAQ)

Q: Can DF33C-3S-3.3C directly replace DF33-3S-3.3C in existing assemblies?

A: Yes. Both connectors share identical electrical and mechanical specifications: 3-position receptacle housings with 0.130" (3.30mm) pitch, female socket contacts, crimp termination, and latch lock fastening. The substitution is functionally direct.

Q: What is the significance of the color difference (Natural vs. White)?

A: Color is a cosmetic attribute and does not affect electrical or mechanical function. Selection between Natural and White depends on application requirements or assembly documentation specifications.

Q: Why is DF33C-3S-3.3C preferred over the original part?

A: DF33-3S-3.3C is obsolete and no longer manufactured. DF33C-3S-3.3C is in active production, ensuring availability and supply chain reliability. Additionally, DF33C-3S-3.3C meets current ROHS3 compliance standards.

Q: Are the contacts included with these connector housings?

A: No. Both DF33-3S-3.3C and DF33C-3S-3.3C are housings only. Contacts must be sourced separately and crimped into the housing.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both connectors have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the operating temperature range critical for substitution?

A: DF33C-3S-3.3C specifies -35°C ~ 85°C operating temperature. This parameter should be verified against application requirements to ensure compatibility with the intended thermal environment.
