Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1850530000 is determined by the following critical parameters:

• Pitch and Position Count: 0.300" (7.62mm) pitch with 10 positions per level ensures mechanical and electrical compatibility with existing PCB layouts
• Mounting Configuration: Through-hole vertical mounting maintains identical board integration
• Wire Termination Method: Screw-clamp TOP termination ensures functional equivalence
• Operating Temperature Range: -50°C ~ 100°C operational envelope must be maintained
• Housing and Contact Materials: Polyamide nylon housing with tin-plated copper contacts ensures environmental and electrical performance
• Compliance Standards: RoHS compliance and REACH unaffected status required for regulatory alignment

The substitute part 1786570000 meets these core substitution criteria while offering enhanced specifications in wire gauge range and current capacity.

Parameter Comparison

Engineering Selection Recommendations

The 1786570000 is the active equivalent for the obsolete 1850530000. Both components maintain identical pitch, position count, mounting orientation, and operating temperature specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 1786570000 provides enhanced specifications including expanded wire gauge compatibility (10-26 AWG versus 14-26 AWG) and documented electrical ratings (30 A at 300 V). Both parts maintain RoHS compliance and REACH unaffected status, supporting regulatory requirements.

The screw thread specification differs between the two parts (M2.5 versus M3), reflecting design evolution within the TOP series. This change does not affect functional substitution for applications using the original 1850530000.

Frequently Asked Questions (FAQ)

Q: Can the 1786570000 directly replace the 1850530000 in existing designs?

A: Yes. Both parts share identical pitch (0.300" / 7.62mm), position count (10), mounting type (through-hole vertical), and wire termination method (screw-clamp TOP). PCB layouts and connector interfaces remain compatible.

Q: What is the significance of the wire gauge range difference?

A: The 1786570000 accepts wire gauges from 10-26 AWG, compared to 14-26 AWG for the 1850530000. This expanded range provides greater flexibility for applications requiring heavier gauge conductors. Existing designs using 14-26 AWG wire remain fully compatible.

Q: Why do the screw threads differ between these parts?

A: The M2.5 thread (1850530000) and M3 thread (1786570000) reflect design improvements in the TOP series evolution. The larger M3 thread in the substitute part provides enhanced clamping force and reliability. Both thread sizes are standard for their respective series.

Q: Are there packaging differences between these parts?

A: The 1850530000 was supplied with unspecified packaging, while the 1786570000 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1850530000 and 1786570000 are RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
