Weidmüller 1776352001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1776352001 is a 24-position terminal block header with male pins, featuring a shrouded 4-side design and 5.08mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential 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 a temperature range of -50°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1776352001 is determined by the following critical parameters:

• Position Count: Must be 24 positions to maintain PCB layout compatibility
• Pitch Tolerance: Nominal pitch of 5.08mm (0.200") or 5.00mm (0.197") within acceptable mechanical tolerance for through-hole mounting
• Header Type: Male pins with shrouded design (2-side or 4-side shrouding acceptable)
• Orientation: Vertical through-hole mounting configuration
• Termination: Solder termination for PCB integration
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Compliance: RoHS compliance and UL94 V-0 flammability rating required for equivalent functionality

The Phoenix Contact 1753877 qualifies as a substitute based on matching position count, compatible pitch specification, vertical orientation, solder termination, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1753877 serves as an active substitute for the obsolete Weidmüller 1776352001. Both components maintain RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence for applications requiring these standards.

The primary consideration for substitution is the current rating differential. The Weidmüller 1776352001 supports 27.5A (IEC) and 18.5A (UL), while the Phoenix Contact 1753877 is rated for 12A under both standards. Selection of the Phoenix Contact substitute is appropriate for applications where the required current does not exceed 12A. For applications requiring current capacity above 12A, the Weidmüller part specifications must be maintained or alternative components with higher current ratings must be evaluated.

The pitch variance between 5.08mm and 5.00mm represents a 0.08mm difference, which falls within standard mechanical tolerance for through-hole PCB mounting. The reduction in shrouding from 4-side to 2-side does not affect electrical performance but may impact mechanical stability in high-vibration environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753877 be used as a direct replacement for the Weidmüller 1776352001?

A: The Phoenix Contact 1753877 is mechanically and electrically compatible for applications where current requirements do not exceed 12A. The 24-position count, vertical orientation, solder termination, and compliance certifications are equivalent. The pitch difference of 0.08mm is within acceptable mechanical tolerance for through-hole mounting.

Q: What is the significance of the shrouding difference (4-side vs. 2-side)?

A: Shrouding provides mechanical protection and alignment during assembly. The 4-side shrouding of the Weidmüller part offers greater mechanical stability, while the 2-side shrouding of the Phoenix Contact part provides equivalent electrical performance with reduced material. For standard PCB mounting applications, both configurations are functionally equivalent.

Q: Are there current rating limitations when substituting the Phoenix Contact part?

A: Yes. The Phoenix Contact 1753877 is rated for 12A maximum (both IEC and UL standards). If your application requires current capacity exceeding 12A, the Weidmüller 1776352001 specifications must be maintained or alternative components with higher current ratings must be sourced.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Weidmüller 1776352001 and Phoenix Contact 1753877 are RoHS compliant and carry UL94 V-0 flammability certification, ensuring regulatory equivalence for applications requiring these certifications.

Q: What is the impact of the 0.08mm pitch difference on PCB design?

A: The pitch difference between 5.08mm and 5.00mm is within standard mechanical tolerance for through-hole PCB footprints. No PCB redesign is required for substitution. Verify that your PCB footprint accommodates the 5.00mm pitch specification of the Phoenix Contact part.
