Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1782490000 is based on the following critical parameters that must remain compatible:

• Pitch spacing: 0.200" (5.08mm) - determines PCB footprint compatibility
• Position count: 15 positions - maintains electrical connectivity requirements
• Mounting type: Through Hole - ensures mechanical installation compatibility
• Voltage rating: Minimum 300 V - maintains electrical safety margins
• RoHS compliance: Required for regulatory alignment
• Connector interface: Wire-to-board terminal block category

The substitute part 1330850000 maintains compatibility across these critical parameters while offering enhanced electrical performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 1330850000 substitute part is suitable for applications requiring replacement of the obsolete 1782490000 based on the following engineering criteria:

Compliance and Status: The 1330850000 maintains active product status with Weidmüller, ensuring continued availability and technical support. Both parts are RoHS compliant and carry identical REACH and ECCN classifications, maintaining regulatory alignment.

Electrical Compatibility: The substitute part exceeds the voltage and current specifications of the original part (300 V / 20 A versus 300 V / 10 A), providing enhanced electrical performance margins. Wire gauge compatibility spans 12-24 AWG for the substitute versus 14-26 AWG for the original, with overlap in the 14-24 AWG range.

Mechanical Considerations: The primary design difference is mating orientation (horizontal versus vertical) and wire termination method (screwless push-in spring versus screw clamp). PCB footprint compatibility is maintained through identical pitch spacing (5.08mm) and position count (15). Through-hole mounting type remains consistent.

Thermal Performance: The substitute part extends the upper operating temperature limit to 120°C compared to 100°C for the original part, providing improved thermal margin for high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the 1330850000 be used as a direct replacement for the 1782490000?

A: The 1330850000 maintains electrical and mechanical compatibility through identical pitch spacing, position count, voltage rating, and through-hole mounting. However, the mating orientation differs (horizontal versus vertical), requiring PCB layout verification. Wire termination method also differs (push-in spring versus screw clamp), necessitating assembly procedure changes.

Q: What are the key differences in wire termination between these parts?

A: The 1782490000 uses screw-type TOP clamp termination requiring torque application of 0.4-0.5 Nm with M2.5 screws. The 1330850000 uses screwless leg spring and push-in spring termination, eliminating screw fastening requirements and reducing assembly time.

Q: Are there wire gauge compatibility concerns?

A: The 1782490000 accepts 14-26 AWG wire, while the 1330850000 accepts 12-24 AWG wire. The overlap range of 14-24 AWG is fully compatible. Applications using 25-26 AWG wire with the original part require verification that 24 AWG maximum rating is acceptable.

Q: Does the horizontal mating orientation of the substitute part affect PCB design?

A: Yes. The 1782490000 features vertical mating orientation (connector enters from above the board), while the 1330850000 features horizontal mating orientation (connector enters from the side). PCB layout, connector positioning, and cable routing must be verified for compatibility with the horizontal orientation.

Q: Are both parts suitable for the same operating temperature range?

A: The 1330850000 extends the upper operating temperature to 120°C compared to 100°C for the 1782490000. Both parts maintain the lower limit of -50°C. Applications operating above 100°C benefit from the substitute part's enhanced thermal rating.
