Key Parameters

Substitute Part Grouping Explanation

Substitution of the 282827-2 terminal block header is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Number of Positions: 2
• Pitch: 0.394" (10.00mm)
• Voltage Rating: 600 V UL
• Current Rating: 24 A UL
• Operating Temperature Range: -40°C to 110°C

Mechanical Compatibility:

• Header Orientation: Vertical
• Mounting Type: Through Hole
• Termination Style: Solder
• Type: Header, Male Pins, Shrouded (2 Side)
• Contact Tail Length: 0.138" (3.50mm)

Material & Compliance:

• Contact Material: Copper Alloy
• Housing Material: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must satisfy all parameters listed above. Variations in non-critical parameters such as housing color and insulation height do not preclude substitution when all electrical, mechanical, and compliance requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1776156-2 is a direct substitute for the obsolete 282827-2 terminal block header. Both components are manufactured by TE Connectivity within the Buchanan series and satisfy identical electrical and mechanical specifications.

Compliance & Certification: Both parts maintain UL94 V-0 material flammability rating, RoHS compliance, and MSL 1 (Unlimited) moisture sensitivity level. The 1776156-2 carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete status of the 282827-2.

Functional Equivalence: The 1776156-2 provides equivalent electrical performance with identical voltage (600 V UL) and current (24 A UL) ratings, operating temperature range (-40°C to 110°C), and contact specifications. The contact tail length (0.138" / 3.50mm) and solder termination style remain unchanged, ensuring compatibility with existing PCB layouts and assembly processes.

Non-Critical Variations: Housing color differs (Green vs. Black) and insulation height varies (0.472" vs. 0.329"), neither of which affects electrical or mechanical function. These variations do not impact substitution suitability for standard applications.

Supply Chain Consideration: Selection of the 1776156-2 is supported by Active product status and documented inventory availability, providing superior long-term supply assurance compared to the Obsolete 282827-2.

Frequently Asked Questions (FAQ)

Q: Can the 1776156-2 be used as a direct replacement for the 282827-2 in existing designs?

A: Yes. The 1776156-2 is a direct substitute for the 282827-2. Both components share identical electrical ratings (600 V UL, 24 A UL), mechanical configuration (2 positions, 10mm pitch, vertical through-hole), and material specifications (Copper Alloy contacts, Polyamide housing, UL94 V-0 rating). The contact tail length and solder termination style are identical, ensuring compatibility with existing PCB designs without modification.

Q: What is the significance of the housing color difference between the two parts?

A: Housing color (Green for 282827-2 vs. Black for 1776156-2) is a cosmetic variation that does not affect electrical performance, mechanical function, or compliance certifications. Color selection does not impact substitution suitability for standard applications.

Q: How does the insulation height variation affect compatibility?

A: The insulation height difference (0.472" for 282827-2 vs. 0.329" for 1776156-2) represents a dimensional variation in the housing structure. This variation does not affect electrical performance or mechanical compatibility with standard PCB through-hole mounting. Component selection should be based on specific board layout requirements; however, both dimensions are within standard terminal block specifications for this product category.

Q: Why is the 282827-2 listed as Obsolete?

A: The 282827-2 carries Obsolete product status, indicating that TE Connectivity has discontinued active production and support for this part number. The 1776156-2 represents the current Active equivalent within the Buchanan series, ensuring ongoing availability and supply chain support.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain equivalent compliance certifications: UL94 V-0 material flammability rating, RoHS compliance, MSL 1 (Unlimited) moisture sensitivity level, and identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. No compliance disadvantages exist with the 1776156-2 substitute.

Q: What is the operating temperature range for both parts?

A: Both the 282827-2 and 1776156-2 operate within the identical temperature range of -40°C to 110°C, ensuring thermal compatibility across standard industrial and commercial applications.

Q: Can the 1776156-2 handle the same current and voltage as the 282827-2?

A: Yes. Both parts are rated for 24 A UL current and 600 V UL voltage. Electrical performance specifications are identical, and the 1776156-2 is fully capable of handling equivalent load conditions.
