Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1802880000 is based on the following critical parameters derived from the provided specifications:

• Pitch: 0.200" (5.08mm) — determines mechanical and electrical compatibility with mating connectors
• Number of Positions: 7 positions — defines circuit capacity and footprint
• Termination Style: Screw-based clamping mechanism — ensures secure wire retention
• Wire Entry Orientation: 180° free-hanging configuration — specifies spatial installation requirements
• Electrical Ratings: Current and voltage specifications must meet or exceed application requirements
• Compliance Standards: RoHS and REACH compliance status must be maintained
• Environmental Specifications: Operating temperature range and moisture sensitivity level

The substitute part 1944140000 maintains compatibility across these critical parameters, enabling direct functional replacement in applications requiring 7-position, 5.08mm pitch terminal block connectivity.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1944140000 serves as the primary substitute for the obsolete 1802880000 based on the following engineering criteria:

Compliance Alignment: Both components maintain identical RoHS Compliant and REACH Unaffected status, ensuring regulatory continuity in applications subject to environmental and hazardous substance restrictions.

Electrical and Mechanical Compatibility: The substitute part preserves critical interface parameters including 7-position configuration, 5.08mm pitch spacing, 180° wire entry orientation, and screw-clamping termination methodology. These parameters ensure direct mechanical and electrical interchangeability within existing circuit designs and PCB layouts.

Active Product Status: The 1944140000 maintains Active product status with current inventory availability, providing supply chain continuity and long-term component sourcing reliability compared to the Obsolete 1802880000.

Environmental Specifications: Identical operating temperature range (-50°C to 100°C) and Moisture Sensitivity Level (MSL 1) confirm suitability for equivalent environmental conditions and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1944140000 directly replace the 1802880000 in existing installations?

A: Yes. Both components share identical pitch (5.08mm), position count (7), wire entry orientation (180°), and termination methodology (screw-clamping). Mechanical and electrical compatibility is maintained across these critical parameters.

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

A: The 1944140000 provides IEC ratings of 23A at 400V and UL ratings of 20A at 300V. Verify that your application requirements do not exceed these specifications before implementation.

Q: Are there packaging differences between the main part and substitute?

A: The 1802880000 packaging is unspecified in available documentation. The 1944140000 is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both components meet the same compliance standards?

A: Yes. Both the 1802880000 and 1944140000 are RoHS Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8536.90.4000.

Q: What wire gauges are compatible with the 1944140000?

A: The substitute part accepts wire gauges from 12-30 AWG or 0.2-4mm². Confirm your application wire specifications fall within this range.

Q: Is the 1944140000 suitable for the same temperature operating range?

A: Yes. Both components operate across -50°C to 100°C, maintaining identical environmental specifications for thermal cycling and extreme temperature applications.
