TE Connectivity AMP Connectors 53416-2 Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 53416-2 is an insulated ring terminal connector designed for circular stud applications. This component is classified as a 14-16 AWG crimp terminal with a 6 stud configuration, manufactured from copper with tin-lead contact finish and PVDF insulation. The part maintains Active product status and is currently available in inventory.

Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable, when packaging requirements differ, or when compliance certifications require updated specifications. Substitutes maintain electrical and mechanical compatibility through matching core parameters including wire gauge, stud size, termination method, and overall dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 53416-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters: Wire gauge (14-16 AWG), contact material (copper), and termination method (crimp) must remain identical to ensure proper current-carrying capacity and connection reliability.

Mechanical Compatibility Parameters: Stud size (6 stud), overall length (0.844"), outer width (0.312"), thickness (0.031"), and insulation diameter range (0.105" ~ 0.150") must match exactly to ensure proper fit within assembly cavities and connection points.

Functional Parameters: Terminal type (circular), mounting configuration (free hanging in-line), and insulation requirement (insulated) must be preserved.

The substitute part 51864-3 maintains equivalence across all critical electrical and mechanical parameters. Variations in contact finish (tin versus tin-lead), insulation material composition (polyamide/nylon versus PVDF), color designation, packaging format, and compliance certifications do not affect functional substitutability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (53416-2): Select the 53416-2 when the application requires tin-lead contact finish specifications or PVDF insulation material properties. This part maintains Active product status with 700 units in current inventory. The tin-lead finish and PVDF insulation provide specific performance characteristics for legacy or specialized applications. Note that this part is RoHS non-compliant.

Substitute Part Selection (51864-3): Select the 51864-3 when RoHS3 compliance is required for the end application. This substitute maintains all critical electrical and mechanical parameters while providing updated compliance certification. The 51864-3 features tin contact finish and polyamide/nylon insulation material. Higher inventory availability (1849 units) and cut tape packaging format support high-volume production requirements. The substitute is suitable for applications where insulation material composition and contact finish variations do not impose functional constraints.

Compliance Considerations: The primary distinction between these parts centers on regulatory compliance status. The 51864-3 achieves ROHS3 compliance, making it the appropriate selection for applications subject to RoHS directives. The 53416-2 remains suitable for applications where RoHS compliance is not mandated or where legacy specifications require tin-lead contact finish.

Frequently Asked Questions (FAQ)

Q: Can 51864-3 be used as a direct replacement for 53416-2 in all applications?

A: The 51864-3 maintains electrical and mechanical compatibility with the 53416-2 across all critical parameters including wire gauge, stud size, termination method, and overall dimensions. However, applications with specific requirements for tin-lead contact finish or PVDF insulation material must retain the 53416-2. Verify that your application does not impose constraints on contact finish composition or insulation material type.

Q: What is the difference between the contact finishes?

A: The 53416-2 features tin-lead contact finish, while the 51864-3 features tin contact finish. Both materials provide electrical conductivity and corrosion resistance suitable for ring terminal applications. The tin-lead finish in the 53416-2 may be specified for legacy applications or specific environmental conditions. The tin finish in the 51864-3 aligns with modern manufacturing standards and RoHS3 compliance requirements.

Q: How do the insulation materials differ?

A: The 53416-2 uses Polyvinylidene Fluoride (PVDF) insulation, while the 51864-3 uses Polyamide (PA) nylon insulation. Both materials provide electrical insulation and mechanical protection for the crimp terminal. PVDF offers specific chemical resistance and temperature performance characteristics. Polyamide nylon provides robust mechanical properties and is widely used in modern connector applications. Select based on your application's environmental and temperature requirements.

Q: What packaging formats are available?

A: The 53416-2 is available in standard packaging format with 700 units in inventory. The 51864-3 is supplied in cut tape (CT) packaging format with 1849 units in inventory. Cut tape packaging supports automated assembly processes and high-volume production environments. Standard packaging may be preferred for manual assembly or lower-volume applications.

Q: Are both parts from the same manufacturer?

A: Both the 53416-2 and 51864-3 are manufactured by TE Connectivity AMP Connectors and belong to the PIDG series. Both parts maintain Active product status and are sourced from the same manufacturer, ensuring consistent quality and reliability standards.

Q: What does RoHS3 compliance mean?

A: RoHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. The 51864-3 meets these regulatory requirements, making it suitable for applications subject to RoHS directives. The 53416-2 is RoHS non-compliant and should be selected only when RoHS compliance is not required.

Q: Can I mix 53416-2 and 51864-3 parts in the same assembly?

A: Both parts are mechanically and electrically compatible and can be used together in the same assembly. However, for consistency and traceability, it is preferable to use a single part number throughout an assembly. If mixing is necessary, document the specific locations and quantities of each part number for quality and compliance records.
