Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CI33T021PE0 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact type: Socket
• Termination method: Crimp
• Contact finish: Tin
• Pitch: 2.54MM (.100)
• Wire gauge overlap within specified range
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The substitute part 0016021110 (Molex SL 71851 series) qualifies as an equivalent based on matching socket contact type, crimp termination, tin finish, and regulatory compliance. Wire gauge specification for the substitute is 22-24 AWG, which represents a subset of the main part's 22-28 AWG range. This subset compatibility permits substitution in applications utilizing 22-24 AWG wire gauges.

Parameter Comparison

Engineering Selection Recommendations

CI33T021PE0 (Primary Selection): Use this part for applications requiring the full 22-28 AWG wire gauge range. Both the main part and substitute maintain Active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory adherence.

0016021110 (Substitute Selection): This Molex part is suitable for applications limited to 22-24 AWG wire gauges. The substitute provides equivalent socket contact performance with crimp termination and tin finish. The increased contact finish thickness (150.0µin versus 80.0µin) does not affect functional compatibility within the specified wire gauge range. Both parts carry identical regulatory certifications and MSL ratings.

Selection between these parts depends on wire gauge requirements within your application design. Applications utilizing 25-28 AWG wire gauges require the CI33T021PE0. Applications utilizing 22-24 AWG wire gauges permit either part selection based on availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0016021110 substitute for the Cvilux CI33T021PE0 in all applications?

A: The Molex part substitutes only for applications using 22-24 AWG wire gauges. Applications requiring 25-28 AWG wire gauge capability must use the CI33T021PE0, as the substitute's wire gauge specification does not extend to these ranges.

Q: What is the significance of the contact finish thickness difference?

A: The CI33T021PE0 has 80.0µin (2.03µm) tin plating, while the 0016021110 has 150.0µin (3.81µm). Both thicknesses meet industry standards for tin-plated socket contacts. The thicker plating on the Molex part provides additional corrosion resistance but does not affect electrical or mechanical compatibility within the specified wire gauge overlap.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CI33T021PE0 and 0016021110 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: Moisture Sensitivity Level 1 indicates these components have unlimited shelf life and require no special moisture control during storage, handling, or assembly. Both parts carry this rating.

Q: Can these parts be used interchangeably in the same connector housing?

A: Both parts are socket contacts with 2.54MM (.100) pitch designed for wire-to-board crimp applications. Physical compatibility with connector housings depends on housing design specifications. Verify housing compatibility with the connector manufacturer's documentation.

Q: What packaging format is available for both parts?

A: Both CI33T021PE0 and 0016021110 are supplied in Cut Tape (CT) packaging format.
