Weidmüller 1775142001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1775142001 is a 16-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. Substitute parts must maintain electrical performance, mechanical compatibility, and regulatory compliance to ensure seamless integration into existing or new applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Number of Positions and Pitch: All substitute parts maintain 16 positions. Pitch variations (5.08mm vs. 5.00mm) represent minor mechanical differences within acceptable tolerance for most applications.
• Header Type and Orientation: All candidates are male-pin, four-sided shrouded headers with 90° right-angle orientation, ensuring mechanical and electrical compatibility.
• Termination and Mounting: All parts use solder termination with through-hole mounting, maintaining PCB integration consistency.
• Electrical Ratings: Substitute parts must support the voltage and current requirements of the application. IEC and UL ratings vary across candidates and must be evaluated against specific circuit demands.
• Regulatory Compliance: RoHS and REACH compliance status ensures environmental and regulatory alignment.
• Product Status: Active-status alternatives provide supply chain continuity and long-term availability advantages over the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1780570000 is the primary substitute for the obsolete 1775142001. Both parts share identical pitch (5.08mm), electrical ratings (27.5A IEC, 18.5A UL), operating temperature range (-50°C ~ 100°C), and flammability certification (UL94 V-0). The 1780570000 is active in production, ensuring supply chain continuity. The primary difference is contact tail length (3.20mm vs. 1.50mm), which may require PCB layout verification but does not affect electrical performance. This part is recommended for direct replacement in existing designs.

Phoenix Contact 1776838 provides an alternative within the same product category. It maintains 16 positions, 90° right-angle orientation, and UL94 V-0 flammability rating. However, the pitch is 5.00mm (vs. 5.08mm), and IEC current rating is reduced to 12A. This part is suitable only for applications where current requirements do not exceed 12A IEC and where the 0.08mm pitch tolerance is acceptable. Operating temperature is not specified, requiring clarification before selection.

On-Shore Technology OSTOQ167551 offers a third alternative with 16 positions and 5.00mm pitch. UL voltage rating (300V) is maintained, but IEC current and voltage ratings are not specified. Operating temperature range (-30°C ~ 105°C) differs from the main part. The insulation height (4.00mm) is significantly reduced compared to other candidates, which may impact mechanical fit. This part should be selected only when electrical specifications are confirmed compatible and mechanical constraints permit the reduced insulation height.

Frequently Asked Questions (FAQ)

Q: Can I use the Phoenix Contact 1776838 as a direct replacement for the Weidmüller 1775142001?

A: The Phoenix Contact 1776838 is mechanically compatible (16 positions, 90° right-angle, four-sided shrouded header) but has reduced electrical ratings. The IEC current rating is 12A compared to 27.5A for the original part. Substitution is valid only if your application current requirements do not exceed 12A IEC. The pitch difference (5.00mm vs. 5.08mm) is within typical mechanical tolerance but requires PCB layout verification.

Q: What is the primary advantage of the Weidmüller 1780570000 over the original 1775142001?

A: The 1780570000 is an active product with identical electrical ratings, pitch, and operating temperature range. It provides supply chain continuity and long-term availability. The contact tail length is longer (3.20mm vs. 1.50mm), which may require PCB design adjustment but does not affect electrical performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Weidmüller 1775142001 and 1780570000 are RoHS Compliant. The Phoenix Contact 1776838 and On-Shore Technology OSTOQ167551 are ROHS3 Compliant. All parts meet current RoHS requirements.

Q: What is the impact of pitch variation between 5.08mm and 5.00mm?

A: The 0.08mm difference is a minor mechanical variation. PCB footprints designed for 5.08mm pitch may accommodate 5.00mm pitch components with minimal adjustment, but layout verification is required. Contact spacing and mating connector compatibility must be confirmed before substitution.

Q: Which substitute part has the best long-term availability?

A: The Weidmüller 1780570000 is the recommended choice for long-term availability. It is an active product from the same manufacturer and series as the obsolete original part, ensuring consistent supply and technical support.

Q: Can I use the On-Shore Technology OSTOQ167551 if electrical specifications are not fully specified?

A: No. The OSTOQ167551 has incomplete electrical specifications (IEC current and voltage not specified). Before selection, confirm that the part meets your application's current and voltage requirements. The significantly reduced insulation height (4.00mm vs. 8.51mm) may also impact mechanical fit and must be verified against your PCB design.
