Substitute Part Grouping Explanation

Substitution of the obsolete 282819-2 is based on electrical and mechanical compatibility within the terminal block header category. The substitute part must satisfy the following critical parameters:

Electrical Compatibility:

Current rating: 15 A (UL)
Voltage rating: 600 V (UL)
Contact material: Copper Alloy with Tin mating finish

Mechanical Compatibility:

Number of positions: 2
Pitch: 0.400" (10.16mm)
Header orientation: 90°, Right Angle
Mounting type: Through Hole
Termination style: Solder
Contact tail length: 0.138" (3.50mm)

Environmental & Compliance:

Operating temperature range: -40°C ~ 110°C
Material flammability rating: UL94 V-0
Moisture sensitivity level: 1 (Unlimited)

The substitute part 1776159-2 meets all critical electrical and mechanical parameters. Variations in housing material specification (Polyamide PA versus Polyamide PA66) and insulation height do not affect functional substitution when the core electrical ratings, pitch, position count, and mounting characteristics remain identical.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1776159-2 is the direct functional substitute for the obsolete 282819-2 terminal block header. Both components share identical electrical ratings (15 A at 600 V), mechanical configuration (2 positions, 10.16mm pitch, 90° right angle), and environmental operating range (-40°C to 110°C).

Product Status Advantage: The 1776159-2 carries Active product status, ensuring ongoing availability and supply chain support. The obsolete 282819-2 presents supply constraints and long-term sourcing risk.

Compliance Status: The 1776159-2 is RoHS Compliant, meeting current regulatory requirements for electronic component manufacturing and distribution. The 282819-2 lists RoHS status as Not applicable, reflecting its obsolete classification.

Physical Considerations: The substitute part features a greater insulation height (0.472" versus 0.329"), which does not compromise electrical or mechanical function but may require verification of clearance in space-constrained PCB layouts. The housing material specification differs slightly (PA versus PA66), though both are polyamide-based materials meeting UL94 V-0 flammability requirements.

Color Differentiation: The substitute is available in black housing versus the original green. This cosmetic difference does not affect electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1776159-2 be used as a direct replacement for the 282819-2 in existing designs?

A: Yes. The 1776159-2 meets all critical electrical and mechanical specifications of the 282819-2, including current rating (15 A), voltage rating (600 V), pitch (10.16mm), position count (2), and mounting type (through-hole solder). The components are functionally equivalent for terminal block header applications.

Q: What is the significance of the different insulation heights?

A: The 1776159-2 has an insulation height of 0.472" compared to 0.329" for the 282819-2. This dimension affects the vertical profile of the component on the PCB. Designs with tight vertical clearance constraints should verify that the increased height does not interfere with adjacent components or enclosure geometry.

Q: Does the housing material difference affect performance?

A: No. Both the original PA66 (Nylon 6/6) and the substitute PA (Nylon) housing materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-40°C to 110°C). The material change does not impact electrical performance or mechanical reliability.

Q: Why is the 282819-2 listed as Obsolete?

A: The 282819-2 has reached end-of-life status within TE Connectivity's product portfolio. The 1776159-2 represents the current active equivalent, ensuring continued availability and compliance with modern regulatory standards including RoHS.

Q: Is the color difference between green and black significant?

A: The color difference is cosmetic and does not affect electrical or mechanical function. Component color is typically used for visual identification or organizational purposes in manufacturing and assembly. The functional performance remains identical.

Q: What is the inventory status for each part?

A: The 282819-2 shows 739 pieces in stock as new original inventory. The 1776159-2 shows 1114 pieces in stock as new original inventory. For long-term production planning, the active status of the 1776159-2 provides greater supply chain assurance compared to the obsolete 282819-2.

Q: Are there any electrical parameter differences between the two parts?

A: No. Both parts maintain identical electrical specifications: 15 A current rating (UL), 600 V voltage rating (UL), copper alloy contacts with tin mating finish, and -40°C to 110°C operating temperature range. Electrical performance is equivalent.

Q: Can the 282819-2 be substituted with other terminal block headers from different manufacturers?

A: Substitution with non-TE Connectivity components requires independent verification of electrical ratings, mechanical dimensions, pitch, position count, and mounting type. The 1776159-2 is the direct equivalent within the TE Connectivity Buchanan series and is the recommended substitute.
