Parameter Comparison

Engineering Selection Recommendations

Both the 1-284512-4 and 1844333 maintain Active product status, ensuring continued manufacturer support and availability. Selection between these components is based on the following engineering considerations:

Primary Selection Criteria:

The 1-284512-4 (TE Connectivity) and 1844333 (Phoenix Contact) are electrically and mechanically equivalent for applications requiring 14-position terminal block headers with 3.5mm pitch, 90° right-angle configuration, and solder termination.

Compliance Alignment:

Both components satisfy ROHS3 compliance requirements and maintain UL94 V-0 flammability ratings, ensuring regulatory compliance in industrial applications. Both components are classified under ECCN EAR99 and HTSUS code 8536.69.4040.

Electrical Performance:

The 1-284512-4 is rated for 11 A (UL standard) at 300 V. The 1844333 provides 12 A (IEC standard) and 8 A (UL standard) at 300 V (UL) and 250 V (IEC). For applications requiring UL certification at 300 V, both components are suitable. Applications requiring IEC compliance at higher current ratings (12 A) should reference the 1844333 specifications.

Mechanical Compatibility:

Insulation height variance between components (0.287" versus 0.285") is within acceptable manufacturing tolerance and does not affect PCB layout or mechanical fit in standard through-hole applications.

Inventory and Lead Time:

The 1-284512-4 maintains 955 pieces in stock. The 1844333 maintains 1157 pieces in stock. Selection may be influenced by immediate availability requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1844333 (Phoenix Contact) directly replace the 1-284512-4 (TE Connectivity) in existing designs?

A: Yes. Both components share identical pitch (3.5mm), position count (14), orientation (90° right-angle), termination style (solder), and mounting type (through-hole). Electrical ratings (300 V UL) and flammability classifications (UL94 V-0) are equivalent. The 0.002" (0.05mm) difference in insulation height is within standard manufacturing tolerance and does not affect PCB layout compatibility.

Q: What are the key electrical differences between these components?

A: The 1-284512-4 is rated for 11 A at 300 V (UL standard). The 1844333 is rated for 12 A at 250 V (IEC standard) and 8 A at 300 V (UL standard). For applications requiring UL certification at 300 V, both components are suitable. Applications requiring higher current capacity should reference IEC ratings on the 1844333.
