Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 172776-4 is based on the following critical parameters that must align for functional equivalence:

Primary Substitution Criteria:

• Contact type: Socket (female receptacle)
• Termination method: Crimp
• Contact finish: Tin
• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance: RoHS compliance status
• ECCN and HTSUS classification alignment

The identified substitute part, Molex 0002081104, operates as a terminal connector with socket (receptacle) configuration and crimp termination. Both components share identical moisture sensitivity ratings (MSL 1), RoHS compliance frameworks, and matching ECCN/HTSUS classifications. However, the wire gauge specifications differ between the main part (18-22 AWG) and the substitute (24-30 AWG), indicating application-specific wire gauge requirements must be evaluated during selection.

Parameter Comparison

Engineering Selection Recommendations

Active Product Availability: The Molex 0002081104 is classified as an active product with current inventory availability (948 pieces in stock), whereas the TE Connectivity 172776-4 is obsolete. For new designs or system replenishment, the active status of the Molex component provides supply chain continuity.

Regulatory Compliance: Both components maintain RoHS compliance status and share identical ECCN and HTSUS classifications, satisfying regulatory requirements for equivalent substitution in controlled environments.

Wire Gauge Consideration: The primary technical distinction between these components is the wire gauge specification. The TE Connectivity 172776-4 accommodates 18-22 AWG wire, while the Molex 0002081104 is specified for 24-30 AWG wire. Selection between these components must be determined by the actual wire gauge requirements of the application circuit.

Moisture and Environmental Performance: Both components share MSL 1 (Unlimited) ratings, indicating equivalent moisture sensitivity performance and suitability for standard industrial and commercial environments without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0002081104 directly replace the TE Connectivity 172776-4 in existing assemblies?

A: Direct replacement depends on wire gauge compatibility. If the application uses 18-22 AWG wire, the Molex component's 24-30 AWG specification represents a different gauge range. Physical and electrical compatibility must be verified against the specific wire gauge in use.

Q: What is the significance of the obsolete status for the TE Connectivity 172776-4?

A: Obsolete status indicates the component is no longer manufactured or supported by TE Connectivity. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Active alternatives such as the Molex 0002081104 provide sustained availability for future procurement.

Q: Are the RoHS compliance statuses equivalent between these components?

A: Both components are RoHS compliant. The TE Connectivity 172776-4 carries RoHS Compliant status, while the Molex 0002081104 carries ROHS3 Compliant status. Both satisfy RoHS regulatory requirements for lead-free and restricted substance compliance.

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

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These components do not require special moisture control during storage, handling, or assembly, and can be stored under standard industrial conditions without desiccant packaging or time-limited shelf life restrictions.

Q: How do the packaging specifications differ between these parts?

A: The TE Connectivity 172776-4 packaging is not specified in available documentation. The Molex 0002081104 is supplied in bulk packaging. Packaging format may affect procurement quantities and handling procedures for integration into manufacturing workflows.

Q: Are there additional substitute options beyond the Molex 0002081104?

A: Based on the provided data, the Molex 0002081104 is the identified substitute. The Molex component documentation references an additional substitute (350221-1), which may provide further alternatives for evaluation.
