Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 282819-4 terminal block header are identified based on strict electrical and mechanical parameter matching within the terminal block category. The substitution logic requires equivalence across the following critical parameters:

Electrical Parameters:

• Number of positions: 4
• Pitch spacing: 0.400" (10.16mm)
• Current rating: 15 A (UL)
• Voltage rating: 600 V (UL)
• Contact material: Copper Alloy
• Contact mating finish: Tin

Mechanical Parameters:

• Header orientation: 90°, Right Angle
• Type configuration: Header, Male Pins, Shrouded (2 Side)
• Termination style: Solder
• Mounting type: Through Hole
• Operating temperature range: -40°C ~ 110°C
• Material flammability rating: UL94 V-0
• Contact tail length: 0.138" (3.50mm)

Parts meeting all these criteria are classified as direct substitutes. Variations in housing color, insulation height, or product status do not affect functional substitutability when all electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1776159-4 terminal block header serves as a direct functional substitute for the obsolete 282819-4 model. Both components share identical electrical ratings (15 A at 600 V), mechanical configuration (4-position, 0.400" pitch, 90° right-angle through-hole), and thermal operating range (-40°C ~ 110°C).

Product Status Consideration: The 282819-4 carries obsolete status, while the 1776159-4 maintains active product status with higher inventory availability (1125 pieces in stock versus 749 pieces). Active status ensures continued manufacturer support, documentation access, and supply chain reliability for new designs and ongoing production.

Compliance and Certification: The 1776159-4 is RoHS Compliant, whereas the 282819-4 carries "Not applicable" RoHS status. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 1776159-4 provides regulatory alignment. Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Physical Differences: The insulation height differs between the two models: 282819-4 measures 0.329" (8.36mm) while 1776159-4 measures 0.472" (12.00mm). Housing color also differs (green versus black). These variations do not affect electrical performance or mechanical compatibility in standard through-hole PCB applications but should be verified against specific board layout and clearance requirements.

Selection Basis: For new designs, production continuity, or replacement scenarios, the 1776159-4 is the appropriate selection due to active product status and RoHS compliance. The 282819-4 remains functionally equivalent for legacy system maintenance where existing inventory or design constraints require the original part number.

Frequently Asked Questions (FAQ)

Q: Can the 1776159-4 directly replace the 282819-4 in existing designs?

A: Yes. Both components meet identical electrical specifications (15 A, 600 V), mechanical configuration (4-position, 0.400" pitch, 90° right-angle through-hole solder termination), and operating temperature range (-40°C ~ 110°C). The primary differences are product status (active versus obsolete), RoHS compliance, housing color, and insulation height. Verify that the increased insulation height of the 1776159-4 (0.472" versus 0.329") does not conflict with board layout or component clearance requirements.

Q: What is the significance of the insulation height difference?

A: The 1776159-4 has an insulation height of 0.472" (12.00mm) compared to the 282819-4 at 0.329" (8.36mm). This 0.143" (3.64mm) increase affects the vertical profile of the assembled connector on the PCB. Verify clearance with adjacent components, enclosure walls, or mechanical constraints before substitution.

Q: Does the housing color difference (green versus black) affect functionality?

A: No. Housing color is a cosmetic and identification feature only. Both green (282819-4) and black (1776159-4) housings are constructed from equivalent polyamide materials with identical UL94 V-0 flammability ratings. Color selection does not impact electrical performance, current capacity, voltage rating, or thermal characteristics.

Q: Why is the 282819-4 marked as obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued active production and support for this part number. The 1776159-4 represents the current active equivalent within the Buchanan series. Obsolete parts may have limited inventory and reduced manufacturer support for technical documentation or design assistance.

Q: Is the 1776159-4 RoHS compliant?

A: Yes. The 1776159-4 is RoHS Compliant, meeting Restriction of Hazardous Substances directives. The 282819-4 carries "Not applicable" RoHS status. For applications requiring RoHS compliance or customer specifications mandating RoHS materials, the 1776159-4 is the appropriate selection.

Q: Are there any electrical performance differences between these parts?

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

Q: What is the contact tail length, and is it the same for both parts?

A: Both the 282819-4 and 1776159-4 have a contact tail length of 0.138" (3.50mm). This dimension defines the solder tail penetration depth into the PCB and is identical between the two models, ensuring equivalent through-hole mounting characteristics.

Q: Can I use the 282819-4 if I have existing inventory?

A: Yes, for legacy system maintenance or repair applications where existing inventory is available. The 282819-4 remains functionally equivalent to the 1776159-4 for all electrical and mechanical applications. However, for new designs or long-term production, the active status and RoHS compliance of the 1776159-4 provide supply chain advantages and regulatory alignment.

Q: What is the pitch specification, and why is it important?

A: Both components feature a 0.400" (10.16mm) pitch, which defines the center-to-center spacing between adjacent positions. This pitch is critical for PCB layout compatibility, mating connector selection, and wire termination spacing. Pitch equivalence ensures direct mechanical and electrical compatibility.

Q: Are both parts suitable for 600 V applications?

A: Yes. Both the 282819-4 and 1776159-4 are rated for 600 V (UL). They are suitable for applications requiring this voltage specification and share identical voltage handling characteristics.
