Weidmüller 1775392001 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Weidmüller 1775392001 is an 18-position terminal block header with male pins, shrouded on four sides, featuring a 0.200" (5.08mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 27.5A at 400V and UL ratings of 18.5A at 300V, with RoHS compliance and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1775392001 is determined by the following critical parameters:

• Electrical Compatibility: Matching pitch (0.200" / 5.08mm), number of positions (18), and header orientation (90° right angle)
• Mechanical Compatibility: Through-hole mounting, solder termination, shrouded (4-side) design, and male pin configuration
• Electrical Ratings: Voltage and current ratings must meet or exceed the application requirements (IEC 400V / 27.5A or UL 300V / 18.5A)
• Compliance & Safety: RoHS compliance and UL94 V-0 flammability rating
• Environmental Specifications: Operating temperature range and contact mating finish (tin)

The Phoenix Contact 1776663 meets the core mechanical and electrical interface requirements, though with reduced current ratings under IEC specification (12A versus 27.5A).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1776663 provides functional substitution for the obsolete Weidmüller 1775392001 in applications where the reduced IEC current rating (12A versus 27.5A) is acceptable. Both components share identical pitch, position count, orientation, and mounting methodology, ensuring mechanical and electrical interface compatibility.

The Phoenix Contact 1776663 holds active product status, ensuring long-term availability and supply chain continuity. Both parts maintain RoHS compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for equivalent applications.

Selection between these components should be based on application current requirements. If the circuit operates within the Phoenix Contact 1776663 current specifications (12A IEC / 15A UL), substitution is directly applicable. Applications requiring the full 27.5A IEC rating of the original Weidmüller component require alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1776663 be used as a direct replacement for the Weidmüller 1775392001?

A: Mechanical and electrical interface compatibility is confirmed. The critical difference is the reduced IEC current rating (12A versus 27.5A). Direct substitution is valid only if circuit current requirements do not exceed 12A at IEC specification or 15A at UL specification.

Q: What are the key compatibility criteria for these terminal block headers?

A: Compatibility is determined by pitch (0.200" / 5.08mm), position count (18), header orientation (90° right angle), mounting type (through hole), termination style (solder), and shrouded design (4-side). Both parts meet these criteria.

Q: Are there differences in housing material between these components?

A: Yes. The Weidmüller 1775392001 uses Liquid Crystal Polymer (LCP) glass-filled housing, while the Phoenix Contact 1776663 uses Polybutylene Terephthalate (PBT). Both materials provide UL94 V-0 flammability rating and are suitable for equivalent thermal and environmental conditions.

Q: What is the significance of the product status difference?

A: The Weidmüller 1775392001 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The Phoenix Contact 1776663 maintains active status, ensuring ongoing supply and support. This makes the Phoenix Contact component the preferred choice for new designs and long-term system maintenance.

Q: Do both components have identical contact tail lengths?

A: No. The Weidmüller 1775392001 has a contact tail length of 0.059" (1.50mm), while the Phoenix Contact 1776663 has 0.138" (4.60mm). This difference may affect PCB layout and solder joint characteristics and should be evaluated during design integration.
