Weidmüller 1793470000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1793470000 is an 8-position terminal block header with male pins, shrouded design, and 0.150" (3.81mm) pitch in 90° right-angle configuration. This component is designed for through-hole solder termination applications requiring reliable electrical connections in industrial and commercial equipment. The part is currently active in production with 795 units in stock. Substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements where alternative manufacturers' components meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1793470000 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: 8 positions, 0.150" (3.81mm) pitch, 300 V UL rating, male pin configuration
Mechanical Compatibility: 90° right-angle orientation, through-hole solder termination, shrouded (4-side) design
Material & Safety Compliance: UL94 V-0 flammability rating, tin contact mating finish, mating flange feature
Physical Form Factor: Green color, matching housing and contact materials within acceptable engineering tolerances

The TE Connectivity AMP Connectors part number 284541-8 meets all critical substitution criteria across these parameters.

Engineering Selection Recommendations

Both the Weidmüller 1793470000 and TE Connectivity 284541-8 are active production components with equivalent electrical and mechanical specifications for standard 8-position, 3.81mm pitch terminal block header applications. Selection between these parts should be based on:

Weidmüller 1793470000 is the primary choice when the extended operating temperature range of -50°C to 120°C is required, or when copper alloy contact material is specified in design documentation.

TE Connectivity 284541-8 is suitable as a substitute when the operating temperature range of -40°C to 110°C is acceptable and when phosphor bronze contact material meets application requirements. This part carries a higher UL current rating of 11 A compared to the Weidmüller's 10 A rating, providing additional margin in current-carrying capacity.

Both parts comply with UL94 V-0 flammability requirements and carry appropriate RoHS certifications. Minor dimensional variations in contact tail length and insulation height fall within acceptable mechanical tolerances for standard PCB through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 284541-8 be used as a direct replacement for Weidmüller 1793470000 in existing designs?

A: Yes, for applications operating within the -40°C to 110°C temperature range. Both parts share identical pitch (3.81mm), position count (8), orientation (90° right angle), shrouded design, and UL voltage rating (300 V). Minor differences in contact material (phosphor bronze vs. copper alloy) and housing material specification do not affect functional compatibility in standard applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) operating temperature range (Weidmüller: -50°C to 120°C; TE: -40°C to 110°C), (2) contact material (Weidmüller: copper alloy; TE: phosphor bronze), (3) housing material specification (Weidmüller: PA with glass fill; TE: PA66), (4) current rating (Weidmüller: 10 A; TE: 11 A), and (5) minor dimensional variations in contact tail length and insulation height.

Q: Are there any compatibility concerns with PCB mounting?

A: Minor dimensional differences in contact tail length (0.126" vs. 0.134") and insulation height (0.278" vs. 0.285") are within standard manufacturing tolerances for through-hole terminal block headers. Both parts are designed for standard PCB mounting with 3.81mm pitch spacing.

Q: Which part should be selected for high-temperature applications?

A: The Weidmüller 1793470000 is specified for operation up to 120°C, making it the appropriate choice for applications requiring extended high-temperature performance. The TE Connectivity part is rated to 110°C maximum.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The Weidmüller part carries RoHS Compliant status, while the TE part carries ROHS3 Compliant status. Both meet current regulatory requirements for their respective product lines.
