Substitute Part Grouping Explanation

Substitution of the TE Connectivity 174737-2 is determined by strict equivalence across the following critical parameters:

Terminal Size, Gender, Number of Positions, Terminal Type, Color, Material, Mounting Type, and Style must remain identical between the main part and any substitute. The Positive Lock EX series designation, PVC construction, and Yellow color specification are non-negotiable functional requirements for direct substitution.

The primary distinction between the main part and its substitute lies in Product Status and Packaging configuration. The 174737-2 is Obsolete with unspecified packaging, while the substitute part maintains Active status with defined Bag packaging. Both parts satisfy RoHS compliance requirements, though through different regulatory frameworks (RoHS versus ROHS3).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2391853-2 is the direct functional equivalent to the 174737-2. Selection of the 2391853-2 is supported by the following engineering criteria:

Product Status: The 2391853-2 maintains Active product status, ensuring continued availability and manufacturer support. The 174737-2 is classified as Obsolete, creating supply risk and limiting access to technical resources.

Regulatory Compliance: Both parts satisfy RoHS requirements. The 2391853-2 carries ROHS3 Compliant certification, representing current regulatory alignment. The 174737-2 carries RoHS Compliant status, which reflects earlier compliance frameworks.

Electrical and Mechanical Equivalence: All functional parameters—terminal size, gender, position count, terminal type, color, material, mounting configuration, and style—are identical between the two parts. This equivalence ensures direct functional interchangeability within 0.187" (4.75mm) Quick Connect/Disconnect applications.

Packaging and Inventory: The 2391853-2 is supplied in Bag packaging with 17,458 pieces in stock, providing immediate availability. The 174737-2 has limited inventory (1,060 pieces) and unspecified packaging.

Frequently Asked Questions (FAQ)

Q: Can the 2391853-2 directly replace the 174737-2 in existing applications?

A: Yes. The 2391853-2 is electrically and mechanically equivalent to the 174737-2 across all functional parameters. Both are 1 Position Sleeve Connectors, Female Receptacle, Yellow, 0.187" (4.75mm), Quick Connect/Disconnect terminals within the Positive Lock EX series. Direct substitution is supported.

Q: What is the primary reason for substituting the 174737-2?

A: The 174737-2 is classified as Obsolete. The 2391853-2 is an Active product with superior availability and ongoing manufacturer support, making it the preferred selection for new designs and ongoing production.

Q: Are there differences in RoHS compliance between these parts?

A: Both parts are RoHS compliant. The 174737-2 carries RoHS Compliant certification, while the 2391853-2 carries ROHS3 Compliant certification. Both satisfy current regulatory requirements for lead-free and restricted substance compliance.

Q: Does packaging differ between the main part and substitute?

A: Yes. The 174737-2 has unspecified packaging, while the 2391853-2 is supplied in Bag packaging. This distinction does not affect functional performance or electrical characteristics.

Q: Are contacts included with either part?

A: No. Both the 174737-2 and 2391853-2 are supplied without contacts. Contacts must be sourced separately for 0.187" (4.75mm) Quick Connect applications.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts suitable for the same Quick Connect/Disconnect applications?

A: Yes. Both parts are designed for use with 0.187" (4.75mm) Quick Connects and are functionally equivalent for all related applications.
