Weidmüller 1775332001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1775332001 is a 12-position terminal block header from the Omnimate SL series, designed for through-hole solder mounting applications. This shrouded male pin header operates at 27.5A (IEC) / 18.5A (UL) and 400V (IEC) / 300V (UL), with a 0.200" (5.08mm) pitch and 90° right-angle orientation. The component is actively produced and RoHS compliant, making it suitable for industrial control and power distribution applications. Equivalent substitute parts may be required due to inventory constraints, design standardization across product lines, or specific application requirements where alternative electrical or mechanical specifications remain within acceptable operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1775332001 is determined by the following critical parameters:

Position Count & Pitch Compatibility: The substitute part must maintain 12 positions with a pitch within the 5.00mm to 5.08mm range to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Electrical Ratings: The substitute must support minimum current and voltage ratings of 12A (IEC) / 15A (UL) and 400V (IEC) / 300V (UL) respectively. The main part's higher current rating (27.5A IEC) establishes the upper performance threshold; substitutes with lower ratings remain acceptable for applications not requiring maximum current capacity.

Mechanical Configuration: Both parts must feature 90° right-angle orientation, male pin headers with shrouded (4-side) design, and through-hole solder termination to maintain form factor and assembly compatibility.

Regulatory Compliance: Both parts must maintain UL94 V-0 flammability rating and RoHS compliance status to satisfy industrial safety and environmental standards.

The Phoenix Contact 1776799 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The Weidmüller 1775332001 remains the specified component for applications requiring the full 27.5A (IEC) current rating and Omnimate SL series integration.

Substitute Selection Criteria: The Phoenix Contact 1776799 is electrically and mechanically compatible for applications operating at or below 12A (IEC) / 15A (UL). Both components maintain identical voltage ratings (400V IEC / 300V UL), UL94 V-0 flammability certification, and active product status. The 0.08mm pitch variance (5.08mm vs. 5.00mm) falls within standard manufacturing tolerances for connector mating interfaces.

Compliance Assurance: Both parts satisfy RoHS requirements and maintain equivalent safety certifications. The Phoenix Contact component carries ROHS3 compliance, which supersedes earlier RoHS standards and confirms continued regulatory alignment.

Application Suitability: Substitution is appropriate for industrial control circuits, power distribution modules, and signal switching applications where current demand does not exceed the Phoenix Contact part's 12A (IEC) / 15A (UL) specification.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1776799 directly replace the Weidmüller 1775332001 in all applications?

A: Direct replacement is suitable only for applications operating at 12A (IEC) or below. If your circuit requires the full 27.5A (IEC) capacity of the Weidmüller part, the Phoenix Contact substitute is not appropriate. Verify your actual current requirements before substitution.

Q: What is the significance of the 0.08mm pitch difference between the two parts?

A: The pitch variance (5.08mm vs. 5.00mm) is within standard connector manufacturing tolerances. Both parts are designed to mate with industry-standard 5.0mm and 5.08mm pitch connector systems. Mechanical compatibility is maintained for standard PCB layouts and mating connector interfaces.

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

A: The Weidmüller 1775332001 specifies -50°C to 100°C operating temperature. The Phoenix Contact 1776799 does not provide an explicit operating temperature range in the available data. For applications requiring confirmed temperature performance across the full -50°C to 100°C range, the Weidmüller part is the specified choice.

Q: Do both parts carry the same safety certifications?

A: Both parts carry UL94 V-0 flammability ratings and maintain RoHS compliance. The Phoenix Contact component is ROHS3 compliant, which represents current regulatory standards. Both parts are suitable for industrial applications requiring these certifications.

Q: What is the difference in housing material between these parts?

A: The Weidmüller 1775332001 uses Liquid Crystal Polymer (LCP) glass-filled housing, while the Phoenix Contact 1776799 uses Polybutylene Terephthalate (PBT). Both materials provide UL94 V-0 flammability performance and are standard for industrial terminal block applications.

Q: Can I use the Phoenix Contact part in a high-current application?

A: No. If your application requires sustained current above 12A (IEC) or 15A (UL), the Phoenix Contact 1776799 is not suitable. The Weidmüller 1775332001 with its 27.5A (IEC) rating must be used for high-current circuits.
