TE Connectivity AMP Connectors 2-936321-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-936321-3 is a 32-position rectangular connector housing designed for plug applications in the Multi-Lock series. This component functions as a connector plug housing with female socket contacts and is classified as an active product. The housing accommodates 32 positions arranged in 4 rows and utilizes crimp termination for contact attachment. Identification of equivalent and substitute parts becomes necessary when the primary part is unavailable, when alternative color specifications are required for application-specific wiring schemes, or when inventory constraints necessitate sourcing from available stock alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of rectangular connector housings within the Multi-Lock series is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Equivalence Criteria:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (32)
• Number of rows (4)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Insulation material (Polybutylene Terephthalate)
• Series designation (Multi-Lock)

The substitute part 3-936321-4 maintains identical specifications across all these parameters. The only variation between the main part and its substitute is the housing color: the primary part features gray insulation, while the substitute features brown insulation. This color differentiation does not affect electrical performance, mechanical compatibility, or functional operation. Both parts share the same base product number (936321), confirming their functional equivalence within the Multi-Lock connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part 2-936321-3 and the substitute part 3-936321-4 are active products with full compliance certifications. The 2-936321-3 carries RoHS Compliant status, while the 3-936321-4 carries ROHS3 Compliant status, indicating that the substitute meets current and enhanced regulatory requirements. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity classification, confirming equivalent handling and storage requirements.

Selection between these parts should be based on application-specific requirements:

Select 2-936321-3 (Gray) when the application specifies gray housing color for wiring identification, circuit board layout conventions, or existing system color-coding standards.

Select 3-936321-4 (Brown) when the application specifies brown housing color, when inventory availability of the gray variant is constrained, or when the enhanced ROHS3 compliance status is required for specific regulatory or procurement frameworks.

Both parts are functionally interchangeable from electrical and mechanical perspectives. The choice between them is determined solely by color specification requirements and regulatory compliance preferences.

Frequently Asked Questions (FAQ)

Q: Can the 3-936321-4 (brown) be used as a direct replacement for the 2-936321-3 (gray)?

A: Yes, the 3-936321-4 is a direct functional equivalent. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, position count, row arrangement, termination method, and insulation material. The only difference is housing color. Substitution is valid when color specification is not a critical requirement for the application.

Q: What is the significance of the color difference between these two parts?

A: The color difference (gray versus brown) is a cosmetic and identification feature only. It does not affect electrical performance, mechanical compatibility, contact integrity, or operational characteristics. Color selection is typically driven by application-specific wiring standards, circuit board layout conventions, or system identification schemes.

Q: Are there any compatibility issues when substituting the brown part for the gray part?

A: No compatibility issues exist. Both parts are manufactured by TE Connectivity AMP Connectors within the Multi-Lock series and maintain identical specifications for all functional parameters. They accept the same crimp contacts, mount identically, and operate within the same environmental and electrical parameters.

Q: What does the difference between RoHS Compliant and ROHS3 Compliant mean?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive, which includes additional restricted substances and more stringent requirements. The substitute part 3-936321-4 meets the more current regulatory standard.

Q: Are the contacts included with these connector housings?

A: No. Both the 2-936321-3 and 3-936321-4 are connector housings only. Contacts are not included and must be sourced separately. The housings are designed to accept crimp-terminated contacts that are compatible with the Multi-Lock series.

Q: What is the significance of the base product number 936321?

A: The base product number 936321 identifies the core connector housing design within the Multi-Lock series. Both the main part and substitute share this base number, confirming they are variants of the same fundamental product design. The different suffixes (2-936321-3 and 3-936321-4) distinguish the color variants.

Q: Can these parts be used in applications requiring specific color coding for safety or identification?

A: Yes, but color selection must match application requirements. If the application specifies gray housing for wiring identification or safety standards, the 2-936321-3 must be used. If brown is specified, the 3-936321-4 must be used. These parts are not interchangeable when color coding is a functional requirement.

Q: What is the Moisture Sensitivity Level (MSL) 1 rating?

A: MSL Level 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture control during storage or handling. This is the least restrictive MSL classification and simplifies inventory management and logistics.
