Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 1850450000 is determined by the following critical parameters that must remain consistent:

• Positions per level: 2
• Pitch spacing: 0.300" (7.62mm)
• Mating orientation: Vertical with Board
• Mounting type: Through Hole
• Wire termination method: Screw - TOP Clamp
• Housing material: Polyamide (PA), Nylon
• Operating temperature range: -50°C ~ 100°C
• RoHS compliance status

The substitute part 0298360000 satisfies all these core requirements. While this substitute belongs to a different series (TOP4GS) and exhibits enhanced electrical ratings and expanded wire gauge compatibility, it maintains mechanical and thermal equivalence with the original component. The substitute is classified as active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The 1850450000 is classified as obsolete, necessitating transition to an active equivalent for new procurements and long-term system support. The substitute part 0298360000 is recommended based on the following factors:

Both components maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements. The substitute is actively manufactured and stocked, ensuring supply chain continuity. Mechanical compatibility is preserved through identical pitch spacing, mounting orientation, and through-hole configuration. Thermal operating range remains unchanged at -50°C to 100°C.

The substitute accommodates a broader wire gauge range (10-26 AWG versus 14-26 AWG), providing design flexibility for applications requiring smaller gauge conductors. The M3 screw thread in the substitute represents a minor mechanical difference from the M2.5 specification of the original part, reflecting the enhanced current-carrying capability (30 A rating) of the substitute design.

Frequently Asked Questions (FAQ)

Q: Can the 0298360000 be used as a direct replacement for the 1850450000 in existing PCB designs?

A: Yes, mechanical compatibility is maintained. Both components share identical pitch spacing (7.62mm), vertical board orientation, and through-hole mounting configuration. PCB footprints designed for the 1850450000 will accommodate the 0298360000 without modification.

Q: What is the significance of the different screw thread specifications (M2.5 versus M3)?

A: The M3 thread in the substitute reflects enhanced mechanical design and increased current capacity. The larger thread diameter provides improved clamping force and contact pressure. This difference does not affect PCB compatibility but may require verification of torque specifications during assembly if automated torque-controlled insertion is employed.

Q: Why does the substitute support a wider wire gauge range (10-26 AWG)?

A: The 0298360000 is designed with enhanced electrical and mechanical specifications. The expanded wire gauge capability reflects improved contact geometry and clamp design, allowing accommodation of smaller conductors while maintaining the original 14-26 AWG range.

Q: Are there packaging differences between these components?

A: The main part 1850450000 is listed with unspecified packaging, while the substitute 0298360000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What is the contact material difference between these parts?

A: The original part uses copper alloy contacts, while the substitute employs electrolytic copper contacts. Both are tin-plated for corrosion resistance and solder compatibility. This material difference reflects manufacturing evolution and does not affect electrical performance in standard applications.
