TE Connectivity AMP Connectors 282963-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 282963-3 is a 3 Position Terminal Block Header with male pins, shrouded on 2 sides, designed for vertical through-hole mounting with 0.295" (7.50mm) pitch spacing. This component is part of the Buchanan series and is actively manufactured. The part operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by electrical compatibility and mechanical fit within the PCB assembly. The primary criteria for equivalency are:

Electrical Parameters:

• Current rating (UL): 15 A minimum
• Voltage rating (UL): 300 V minimum
• Contact mating finish: Tin
• Material flammability rating: UL94 V-0

Mechanical Parameters:

• Number of positions: 3
• Header orientation: Vertical
• Mounting type: Through hole
• Termination style: Solder
• Pitch spacing: 0.295" (7.50mm) to 0.300" (7.62mm) range

Compliance Parameters:

• RoHS compliance status
• ECCN classification: EAR99

The substitute part ELFH03450 meets the electrical requirements and maintains vertical through-hole solder termination. The pitch variance of 0.005" (0.12mm) between 7.50mm and 7.62mm falls within acceptable tolerance for standard PCB layout spacing in this component category. The substitute features 4-side shrouding compared to the main part's 2-side shrouding, providing enhanced mechanical protection.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity AMP Connectors 282963-3 and the Amphenol PCD ELFH03450 are active products with current manufacturing status and full regulatory compliance. Selection between these parts is based on the following engineering considerations:

282963-3 Selection Criteria:

• Primary sourcing option with established supply chain
• 2-side shrouding design for standard applications
• Operating temperature range of -40°C to 110°C
• RoHS Compliant certification
• Moisture Sensitivity Level 1 (Unlimited)

ELFH03450 Selection Criteria:

• Alternative sourcing with higher inventory availability (1405 Pcs vs. 861 Pcs)
• Enhanced mechanical protection with 4-side shrouding
• ROHS3 Compliant certification (updated RoHS standard)
• Pitch spacing of 0.300" (7.62mm) requires PCB layout verification
• Maximum operating temperature of 105°C

Both parts satisfy the electrical requirements of 15 A at 300 V with UL94 V-0 flammability rating and tin contact mating finish. The pitch difference of 0.005" (0.12mm) must be evaluated against specific PCB design constraints. The substitute part's 4-side shrouding provides additional mechanical robustness compared to the main part's 2-side configuration.

Frequently Asked Questions (FAQ)

Q: Can ELFH03450 be used as a direct replacement for 282963-3 in existing designs?

A: Electrical compatibility is confirmed; both parts operate at 15 A and 300 V with identical contact finish and flammability ratings. However, the pitch spacing differs by 0.005" (7.50mm vs. 7.62mm). PCB layout verification is required to confirm that the 0.12mm spacing variance does not conflict with existing hole patterns or trace routing.

Q: What is the difference between 2-side and 4-side shrouding?

A: The main part features 2-side shrouding, providing lateral protection. The substitute part features 4-side shrouding, which provides protection on all four sides of the header. This affects the mechanical envelope and insertion force characteristics. Physical fit verification in the target assembly is necessary.

Q: Are both parts RoHS compliant?

A: Yes. The 282963-3 is RoHS Compliant. The ELFH03450 is ROHS3 Compliant, which represents the updated RoHS standard. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature difference between these parts?

A: The 282963-3 operates from -40°C to 110°C. The ELFH03450 specifies a maximum operating temperature of 105°C. For applications requiring operation at temperatures between 105°C and 110°C, the main part is the appropriate selection.

Q: How do the contact materials differ?

A: The 282963-3 uses Copper Alloy contacts. The ELFH03450 uses Brass contacts. Both materials with tin mating finish provide equivalent electrical performance for this application category.

Q: What packaging differences exist between these parts?

A: The 282963-3 is supplied in standard packaging. The ELFH03450 is supplied in Bulk packaging. Packaging format may affect handling, storage, and integration into manufacturing processes.

Q: Are both parts suitable for solder termination?

A: Yes. Both parts use solder termination style and are designed for through-hole PCB mounting. Soldering parameters and thermal profiles should follow the respective manufacturer specifications.
