Weidmüller 1775932001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1775932001 is a 3-position terminal block header with male pins, shrouded on 4 sides, designed for vertical through-hole mounting with 5.08mm pitch. This component is part of the Omnimate SL series and maintains active product status. Alternative components may be required due to inventory constraints, regional availability, or specific application requirements where compatible electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 1775932001 are identified based on the following critical parameters that determine functional compatibility:

• Number of Positions: 3 positions (fixed requirement)
• Pitch Tolerance: 0.200" (5.08mm) nominal, with 0.198" (5.03mm) acceptable within standard connector tolerances
• Mounting Configuration: Vertical through-hole solder termination
• Shrouding: 4-side shrouded design
• Connector Type: Header with male pins or compatible contact configuration
• Electrical Performance: Current and voltage ratings must meet or exceed application requirements
• Flammability Rating: UL94 V-0 or equivalent material classification
• RoHS Compliance: Required for regulatory alignment

The Molex 3099 series components (0010181033 and 0010181038) meet these substitution criteria through compatible pitch spacing, 3-position configuration, vertical through-hole mounting, and 4-wall shrouding design.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1775932001 remains the primary specification component with active product status, RoHS compliance, and UL94 V-0 flammability rating. This part is suitable for applications requiring the highest material flammability classification and extended low-temperature operation to -50°C.

Molex 0010181033 provides functional equivalence with 3-position, vertical through-hole configuration and 4-wall shrouding. This part maintains UL94 V-0 flammability rating and ROHS3 compliance. The 0.198" pitch represents a 0.002" (0.05mm) deviation from the primary specification, which falls within standard connector manufacturing tolerances. This substitute is appropriate where inventory availability or lead time considerations apply.

Molex 0010181038 offers the same mechanical and electrical configuration as 0010181033 with documented operating temperature range of -40°C to 105°C and specified current rating of 5A at 250V. The material flammability rating is UL94 V-2, which represents a lower classification than the primary part. This substitute is suitable for applications where the reduced flammability rating is acceptable and the narrower low-temperature limit (-40°C minimum) meets operational requirements.

Frequently Asked Questions (FAQ)

Q: Can Molex 0010181033 and 0010181038 be used interchangeably with the Weidmüller 1775932001?

A: Both Molex parts provide functional substitution based on matching 3-position configuration, vertical through-hole mounting, 5.03mm pitch spacing (within tolerance of 5.08mm), and 4-wall shrouding. Pitch tolerance of ±0.05mm is standard in connector design. Selection between these parts depends on specific flammability and temperature requirements of the application.

Q: What is the significance of the pitch difference between 5.08mm and 5.03mm?

A: The 0.05mm difference represents a 1% deviation and falls within standard connector manufacturing tolerances. This spacing is compatible with standard PCB layouts designed for 0.200" (5.08mm) pitch headers, as connector design standards accommodate this tolerance range.

Q: Why does Molex 0010181038 have a UL94 V-2 rating instead of V-0?

A: Material flammability classification is determined by the insulation material composition. The Weidmüller part uses Liquid Crystal Polymer (LCP) with glass fill rated UL94 V-0, while Molex 0010181038 uses Polyester rated UL94 V-2. Applications requiring V-0 classification must use either the primary Weidmüller part or Molex 0010181033.

Q: Are there temperature operating range limitations when substituting parts?

A: The Weidmüller 1775932001 operates from -50°C to 100°C. Molex 0010181038 operates from -40°C to 105°C. If the application requires operation below -40°C, the Weidmüller part or Molex 0010181033 must be used. Both substitute parts maintain ROHS3 compliance and are suitable for standard industrial temperature ranges.

Q: Do all three parts have equivalent electrical ratings?

A: The Weidmüller part specifies 27.5A at 400V (IEC) and 18.5A at 300V (UL). Molex 0010181038 specifies 5A at 250V. For applications requiring the higher current and voltage ratings of the Weidmüller specification, verify that substitute parts meet the electrical requirements of the specific application circuit.
