282963-8 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 282963-8 is an 8-position terminal block header with male pins, shrouded on two sides, designed for vertical through-hole mounting with 7.5mm pitch spacing. This component is classified as obsolete, which necessitates identification of functionally equivalent substitute parts for ongoing design support and procurement continuity. The terminal block operates at 15A (UL) and 300V (UL) with an operating temperature range of -40°C to 110°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 282963-8 terminal block header is based on strict electrical and mechanical parameter matching within the Buchanan series. The substitute part 1776149-8 qualifies as a direct equivalent because it maintains identical specifications across all critical parameters: 8-position configuration, 7.5mm pitch, vertical orientation, male pin shrouded header type, through-hole solder termination, 15A UL current rating, 300V UL voltage rating, -40°C to 110°C operating temperature range, copper alloy contacts, polyamide housing, UL94 V-0 flammability rating, 3.50mm contact tail length, and 12.00mm insulation height.

The primary distinction between the main part and substitute is product status and compliance certification. The 282963-8 is obsolete with no RoHS compliance statement, while the 1776149-8 is active and RoHS compliant. The housing color differs (green versus black), which is a cosmetic variation that does not affect electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 1776149-8 terminal block header is the appropriate substitute for the obsolete 282963-8 based on complete electrical and mechanical parameter equivalence. All functional specifications match exactly: 8-position configuration, 7.5mm pitch, vertical through-hole solder termination, 15A/300V ratings, and -40°C to 110°C operating range.

The 1776149-8 provides additional advantages for new designs and procurement: active product status ensures ongoing availability and manufacturer support, and RoHS compliance certification satisfies regulatory requirements for applications subject to RoHS directives. The housing material specification (polyamide/nylon) is equivalent across both parts and maintains the UL94 V-0 flammability rating.

The color difference (black versus green) is a cosmetic variation that does not affect electrical performance, mechanical fit, or thermal characteristics. This substitution is suitable for direct replacement in existing designs without circuit modification or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the 1776149-8 be used as a direct replacement for the 282963-8 in existing designs?

A: Yes. The 1776149-8 maintains identical electrical ratings (15A/300V), mechanical dimensions (8-position, 7.5mm pitch, vertical orientation), contact specifications (copper alloy, tin finish, 3.50mm tail length), and thermal operating range (-40°C to 110°C). No circuit or PCB modifications are required.

Q: Does the color difference between the parts affect compatibility?

A: No. The color difference (green for 282963-8, black for 1776149-8) is a housing cosmetic variation only. It does not affect electrical performance, mechanical fit, thermal characteristics, or functional operation.

Q: What is the significance of the RoHS compliance difference?

A: The 1776149-8 is RoHS compliant, while the 282963-8 has no RoHS status. For applications subject to RoHS directives or customer requirements, the 1776149-8 is the appropriate selection. Both parts use equivalent materials and maintain identical electrical specifications.

Q: Are the housing materials equivalent between the two parts?

A: Yes. Both parts use polyamide (nylon) housing materials with UL94 V-0 flammability rating. The 282963-8 specifies PA66/Nylon 6/6, while the 1776149-8 specifies PA/Nylon. These materials are functionally equivalent for this application.

Q: Why is the 282963-8 classified as obsolete?

A: The 282963-8 is an older product in the Buchanan series. The 1776149-8 represents the current active equivalent, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The parts are mechanically and electrically interchangeable. Identical pitch spacing (7.5mm), contact tail length (3.50mm), insulation height (12.00mm), and solder termination specifications ensure compatibility with the same PCB footprint and connector mating interface.

Q: What is the current inventory status for these parts?

A: The 282963-8 has 627 pieces in stock (obsolete status). The 1776149-8 has 904 pieces in stock (active status). For new procurement, the 1776149-8 is the recommended selection due to active product status and superior availability assurance.
