Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1546227-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (12 A), voltage rating (300 V), and wire gauge acceptance (14-30 AWG) must remain identical.

Mechanical Compatibility: The 12-position configuration, 3.5mm pitch, horizontal mating orientation, through-hole mounting type, and screw-based rising cage clamp termination must be preserved.

Termination Specifications: Screw thread type (M3) and torque specification (0.25 Nm) must match to ensure proper installation and performance.

Material and Contact Specifications: Housing material (Polyamide PA66), contact plating (Brass - Tin Plated), clamp plating (Brass - Nickel Plated), and screw plating (Brass - Nickel Plated) establish the baseline for acceptable substitutes.

The substitute part 1-284391-2 meets all these criteria while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-284391-2 provides full functional equivalence to the obsolete 1-1546227-2 across all critical electrical and mechanical parameters. Both components share identical specifications for position count, pitch, current and voltage ratings, wire gauge acceptance, mounting configuration, and termination method.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 1-284391-2 is classified as active product with ROHS3 compliance and REACH affected status, whereas the 1-1546227-2 is obsolete with undefined REACH status. For new designs or ongoing procurement, the 1-284391-2 is the appropriate selection due to its active status and current regulatory alignment.

Both parts are manufactured by TE Connectivity within the Buchanan series and maintain identical material specifications, contact plating, and torque requirements. The 1-284391-2 is available in bulk packaging with higher inventory levels (1495 units) compared to the main part (852 units).

Frequently Asked Questions (FAQ)

Q: Can the 1-284391-2 be used as a direct replacement for the 1-1546227-2 in existing designs?

A: Yes. The 1-284391-2 meets all electrical and mechanical specifications of the 1-1546227-2. Both components have identical position count (12), pitch (3.5mm), current rating (12A), voltage rating (300V), wire gauge range (14-30 AWG), mounting type (through-hole), and termination method (screw-based rising cage clamp). PCB layout and assembly procedures remain unchanged.

Q: What is the difference in color between these two parts?
