TE Connectivity AMP Connectors 5-146283-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5-146283-3 is an active rectangular connector header designed for through-hole board-to-board applications. This unshrouded, breakaway connector features 3 positions with 0.100" (2.54mm) pitch spacing and is part of the AMPMODU Mod II series. The connector utilizes male pins with gold-plated mating contacts and tin-plated solder posts, constructed from copper alloy with liquid crystal polymer (LCP) insulation.

Substitute parts are identified to address inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility within the defined parameter tolerance range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility:

Primary Compatibility Criteria:

• Connector Type: Header, Breakaway (form factor match)
• Contact Type: Male Pin (mating interface match)
• Pitch - Mating: 0.100" (2.54mm) (mechanical interchangeability)
• Number of Positions: 3 (circuit configuration match)
• Number of Rows: 1 (layout match)
• Mounting Type: Through Hole (assembly method match)
• Termination: Solder (connection method match)
• Fastening Type: Push-Pull (mating mechanism match)
• Contact Finish - Mating: Gold (electrical performance match)
• Contact Finish - Post: Tin (solder joint compatibility)

Secondary Compatibility Parameters:

• Operating Temperature Range: Substitute must meet or exceed the minimum range of -65°C ~ 105°C
• Shrouding: Unshrouded (physical form factor)
• Style: Board to Board or Board to Board/Cable (application compatibility)

Allowable Variations:

• Contact material composition (copper alloy vs. phosphor bronze) within electrical performance equivalence
• Insulation material (LCP vs. PBT) within mechanical and thermal performance equivalence
• Contact length specifications within functional tolerance
• Insulation height within mechanical tolerance
• Contact finish thickness within performance specification

The substitute part PBC03SAAN from Sullins Connector Solutions meets all primary and secondary compatibility criteria and is therefore classified as an equivalent substitute.

Engineering Selection Recommendations

Primary Selection: TE Connectivity 5-146283-3

Use the original TE Connectivity AMP Connectors 5-146283-3 when:

• AMPMODU Mod II series specification is required
• Copper alloy contact material is specified in design documentation
• LCP insulation material is required for specific application constraints
• Exact contact post length of 0.090" (2.29mm) is critical to PCB layout
• Original manufacturer part traceability is required for quality assurance

Substitute Selection: Sullins PBC03SAAN

Use the Sullins Connector Solutions PBC03SAAN as an equivalent substitute when:

• TE Connectivity 5-146283-3 is unavailable or subject to extended lead times
• Inventory availability is a primary constraint
• Operating temperature range up to 125°C is acceptable or beneficial
• Phosphor bronze contact material meets application requirements
• PBT insulation material is acceptable for the application
• Slightly increased contact post length (0.120" vs. 0.090") is compatible with PCB design
• Board-to-board or board-to-cable application flexibility is beneficial
• RoHS3 compliance and UL94 V-0 flammability rating are required

Compliance Considerations:

Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The Sullins substitute provides additional compliance documentation including RoHS3 compliance and UL94 V-0 material flammability rating, which may be advantageous for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can PBC03SAAN be used as a direct replacement for 5-146283-3 in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (3), row configuration (1), contact type (male pin), and mating contact finish (gold). The mechanical and electrical interfaces are compatible. Variations in contact post length (0.120" vs. 0.090") and insulation height (0.100" vs. 0.090") are within functional tolerance for standard through-hole PCB applications.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Contact material: copper alloy vs. phosphor bronze; (2) Insulation material: LCP vs. PBT; (3) Operating temperature upper limit: 105°C vs. 125°C; (4) Contact post length: 0.090" vs. 0.120"; (5) Insulation height: 0.090" vs. 0.100"; (6) Contact finish thickness on mating surface: 5.00µin vs. 10.0µin. These variations do not affect compatibility for standard board-to-board applications.

Q: Are there any packaging differences between these parts?

A: Yes. The TE Connectivity 5-146283-3 packaging specification is not provided in the data. The Sullins PBC03SAAN is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Does the Sullins substitute have any compliance advantages?

A: The Sullins PBC03SAAN includes documented RoHS3 compliance and UL94 V-0 material flammability rating. The TE Connectivity 5-146283-3 material flammability rating is not specified in the provided data. If these certifications are required for your application, the Sullins part provides explicit compliance documentation.

Q: Can I mix these connectors in the same assembly?

A: Both connectors are mechanically and electrically compatible for board-to-board mating. However, mixing different manufacturers in a single assembly may complicate traceability and quality documentation. Standardize on a single part number per assembly when possible.

Q: What is the current rating for these connectors?

A: The TE Connectivity 5-146283-3 current rating is not specified in the provided data. The Sullins PBC03SAAN is rated for 3A per contact. Confirm current requirements with your circuit design specifications before selection.

Q: Are voltage ratings specified for these connectors?

A: Voltage ratings are not specified in the provided data for either connector. Consult the manufacturer datasheets or contact technical support for voltage rating information if this parameter is critical to your application.

Q: What is the temperature operating range difference?

A: The TE Connectivity 5-146283-3 operates from -65°C to 105°C. The Sullins PBC03SAAN operates from -65°C to 125°C. The Sullins substitute provides a 20°C higher upper temperature limit, which may be beneficial for high-temperature applications but is not required for standard industrial temperature ranges.
