Weidmüller 1776262001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1776262001 is a 15-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the Omnimate SL series and is classified as obsolete. Due to its obsolete status, identifying active equivalent parts is essential for ongoing design support, maintenance, and new production requirements. The substitute part 1838340000 provides functional continuity while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 1776262001 is determined by strict equivalence across the following critical parameters:

Electrical Performance: Current and voltage ratings (IEC and UL standards) must match exactly
Physical Configuration: Number of positions (15), pitch (5.08mm), header orientation (vertical), and shrouding (4-side) must be identical
Mounting and Termination: Through-hole solder termination is mandatory
Material and Compliance: UL94 V-0 flammability rating, RoHS compliance, and contact material (copper alloy) must be maintained
Operating Environment: Temperature range (-50°C ~ 100°C) must be supported

The substitute part 1838340000 meets all these criteria. The primary difference is the contact tail length (1.50mm vs. 3.20mm), which represents a design variation within the same functional family and does not affect electrical or mechanical compatibility in standard applications.

Engineering Selection Recommendations

The 1838340000 is the direct functional equivalent to the 1776262001. Selection of the substitute part is justified on the following grounds:

Product Status: The 1776262001 is classified as obsolete, creating supply chain risk and limiting long-term availability. The 1838340000 maintains active product status, ensuring continued support and procurement reliability.

Compliance and Certifications: Both parts maintain identical RoHS compliance and UL94 V-0 flammability ratings, meeting regulatory requirements for equivalent applications.

Electrical and Mechanical Equivalence: All critical parameters—electrical ratings (IEC and UL), physical configuration, mounting method, and material specifications—are identical between the two parts.

Contact Tail Length Consideration: The 1838340000 features a longer contact tail (3.20mm vs. 1.50mm). This variation is a design improvement within the Omnimate SL family and does not compromise compatibility in standard through-hole PCB applications. The longer tail provides enhanced solder joint reliability and mechanical stability.

Frequently Asked Questions (FAQ)

Q: Can 1838340000 be used as a direct replacement for 1776262001 in existing designs?

A: Yes. The 1838340000 is electrically and mechanically equivalent. All critical parameters match, including position count, pitch, voltage/current ratings, and operating temperature range. The longer contact tail (3.20mm vs. 1.50mm) is a design enhancement that improves solder joint formation without affecting functional compatibility.

Q: What is the primary reason for substitution?

A: The 1776262001 is obsolete. The 1838340000 provides the same functionality with active product status, ensuring availability and ongoing manufacturer support.

Q: Are there packaging differences between these parts?

A: The 1776262001 is listed with unspecified packaging, while the 1838340000 is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, and meet IEC and UL electrical standards. Compliance certifications are equivalent.

Q: Will the longer contact tail of 1838340000 affect PCB layout?

A: No. The longer contact tail (3.20mm) is accommodated within standard through-hole PCB designs. This variation is within the design tolerance of the Omnimate SL series and does not require layout modifications.

Q: Are there any applications where 1776262001 cannot be substituted with 1838340000?

A: No restrictions are identified based on the provided specifications. Both parts operate across the same temperature range (-50°C ~ 100°C) and support identical electrical ratings.
