Weidmüller 1774872001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1774872001 is a 13-position terminal block header with male pins, shrouded on 2 sides, designed for 0.200" (5.08mm) pitch right-angle through-hole mounting. This component is part of the Omnimate SL series and maintains active product status. Substitute parts may be required due to inventory constraints, design modifications for enhanced mechanical protection, or specific application requirements for alternative shrouding configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1774872001 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 13 positions at 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
• Header Orientation & Mounting: Right-angle through-hole configuration must be preserved for mechanical fit
• Electrical Ratings: Voltage and current ratings must meet or exceed application requirements
• Termination Style: Solder termination is required for direct PCB integration
• Series Compatibility: Omnimate SL series designation ensures connector family consistency
• Compliance: RoHS compliance and operating temperature range must be maintained

The substitute part 1155700000 qualifies based on these criteria, with the primary design difference being enhanced shrouding (4-side vs. 2-side) and corresponding adjustments to mechanical dimensions and housing material.

Parameter Comparison

Engineering Selection Recommendations

Both the 1774872001 and 1155700000 maintain active product status and full RoHS compliance, qualifying them for equivalent use in applications requiring 13-position, 5.08mm pitch terminal block headers with right-angle through-hole mounting.

The 1774872001 is suitable for applications where 2-side shrouding provides adequate mechanical protection and space constraints limit component height to 0.335" (8.51mm).

The 1155700000 offers enhanced mechanical protection through 4-side shrouding and interlocking features, accommodating applications requiring increased robustness. The increased insulation height of 0.472" (12.00mm) and longer contact tail length of 0.126" (3.20mm) must be verified against PCB layout and clearance requirements. The IEC current rating of 24A remains suitable for most industrial applications, though designs operating above 24A IEC should retain the 1774872001.

Both parts operate across the identical temperature range (-50°C to 100°C) and maintain equivalent UL electrical ratings (18.5A, 300V).

Frequently Asked Questions (FAQ)

Q: Can 1155700000 directly replace 1774872001 on existing PCBs?

A: Direct replacement requires verification of mechanical clearance. The 1155700000 has a taller insulation height (0.472" vs. 0.335") and longer contact tail (0.126" vs. 0.059"), which may conflict with adjacent components or through-hole spacing. PCB layout review is necessary before substitution.

Q: What is the functional difference between 2-side and 4-side shrouding?

A: The 1774872001 provides shrouding on two sides, while the 1155700000 provides complete 4-side shrouding with interlocking features. The 4-side configuration offers enhanced protection against accidental contact and improved mechanical stability in high-vibration environments.

Q: Are there current rating limitations when substituting?

A: The 1155700000 has an IEC current rating of 24A compared to the 1774872001's 27.5A. Applications requiring currents between 24A and 27.5A IEC must retain the original part number. Both parts share identical UL ratings (18.5A, 300V).

Q: Do both parts use the same PCB footprint?

A: Both parts maintain identical pitch (5.08mm) and position count (13), ensuring footprint compatibility. However, the increased mechanical dimensions of the 1155700000 require clearance verification for surrounding components.

Q: Are both parts suitable for industrial control applications?

A: Yes. Both parts are RoHS compliant, operate across -50°C to 100°C, and maintain UL and IEC certifications suitable for industrial control, automation, and power distribution applications.
