• 7.5mm (0.295") pitch spacing
• 15 A current rating (UL)
• 300 V voltage rating (UL)
• Copper alloy contact material with tin mating finish

Mechanical Parameters:

• Vertical through-hole mounting orientation
• Male pins with two-side shrouding
• Solder termination style
• 0.138" (3.50mm) contact tail length
• 0.472" (12.00mm) insulation height
• UL94 V-0 flammability rating
• Operating temperature range of -40°C to 110°C

Compliance Parameters:

• Moisture Sensitivity Level 1 (Unlimited)
• ECCN EAR99 classification
• HTSUS 8536.69.4040 tariff code

The substitute part TE Connectivity 1-1776149-0 meets all these criteria and is classified as active product status, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1776149-0 is the direct functional equivalent for the obsolete 1-282963-0 terminal block header. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity, ensuring continued availability, technical support, and manufacturing consistency. The main part's obsolete classification creates supply chain risk that is eliminated through substitution.

Electrical and Mechanical Equivalence: All critical electrical parameters (current rating, voltage rating, contact material, and mating finish) are identical. All mechanical parameters (position count, pitch spacing, orientation, mounting type, contact tail length, and insulation height) are identical. These parameters determine functional interchangeability in circuit applications.

Compliance and Certification: Both parts carry identical UL94 V-0 flammability ratings, ECCN EAR99 classification, and HTSUS tariff codes. The substitute part achieves RoHS compliance, providing enhanced environmental and regulatory alignment for modern manufacturing and end-use applications.

Housing Material Specification: The substitute part specifies polyamide (PA) nylon material, which is functionally equivalent to the main part's polyamide (PA66) nylon 6/6 specification. Both materials meet the UL94 V-0 flammability requirement and maintain identical thermal and electrical performance within the specified operating temperature range.

Color Differentiation: The substitute part is available in black housing versus the main part's green housing. This cosmetic difference does not affect electrical or mechanical function and does not impact circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can the 1-1776149-0 be used as a direct replacement for the 1-282963-0 in existing designs?

A: Yes. The 1-1776149-0 is electrically and mechanically equivalent to the 1-282963-0 across all critical parameters including position count, pitch spacing, current and voltage ratings, contact materials, mounting configuration, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the difference between the green housing of the main part and the black housing of the substitute?

A: Housing color is a cosmetic specification that does not affect electrical performance, mechanical function, or reliability. Both colors are available within the Buchanan series and meet identical performance and compliance standards.

Q: Are there differences in the housing material between these parts?

A: The main part specifies polyamide (PA66) nylon 6/6, while the substitute specifies polyamide (PA) nylon. Both materials are polyamide-based thermoplastics that meet UL94 V-0 flammability requirements and provide equivalent thermal and electrical performance within the -40°C to 110°C operating range.

Q: Does the substitute part meet RoHS compliance requirements?

A: Yes. The 1-1776149-0 is RoHS compliant, whereas the main part's RoHS status is listed as not applicable. This provides enhanced compliance alignment for applications subject to RoHS directives and modern environmental regulations.

Q: Are the contact tail lengths and insulation heights identical?

A: Yes. Both parts maintain identical contact tail length of 0.138" (3.50mm) and insulation height of 0.472" (12.00mm). These dimensions ensure identical PCB footprint compatibility and mounting characteristics.

Q: What is the current availability status of the substitute part?

A: The 1-1776149-0 is classified as active product status with TE Connectivity, ensuring ongoing manufacturing, inventory availability, and technical support. This contrasts with the main part's obsolete status, which creates long-term supply chain uncertainty.

Q: Are both parts rated for the same electrical specifications?

A: Yes. Both parts are rated for 15 A current (UL) and 300 V voltage (UL) with identical copper alloy contact material and tin mating finish. Electrical performance and safety ratings are equivalent.

Q: Can these parts be used interchangeably in new designs?

A: Yes. The 1-1776149-0 can be specified in new designs as the preferred active alternative to the obsolete 1-282963-0. All electrical, mechanical, and compliance parameters support direct interchangeability.
