Altech Corporation 40.003 Eurostyle Terminal Strip - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 40.003 is a 3-circuit Eurostyle terminal strip connector with 0.315" (8.00mm) pitch spacing, designed for industrial control and power distribution applications. This component features screw-type termination on the top and a closed bottom configuration, suitable for chassis and panel mounting. The part is currently active in production with 888 units in stock. Alternative components may be required due to inventory constraints, application-specific voltage or current requirements, or regional compliance preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Altech 40.003 is determined by the following critical parameters:

Core Compatibility Requirements:

• Terminal block type: Eurostyle Terminal Strip
• Number of circuits: 3
• Pitch spacing: 0.315" (8.00mm)
• Wire gauge compatibility: 12-22 AWG
• Termination method: Screw-type top termination
• Bottom configuration: Closed

Allowable Variations:

• Current rating: Substitute must meet or exceed 20A
• Voltage rating: Substitute must meet or exceed 300V
• Operating temperature range: Substitute must cover the application's required temperature window
• Flammability rating: Substitute must meet or exceed UL94 V-0
• RoHS compliance: ROHS3 Compliant status required

The TE Connectivity AMP Connectors part number 1776293-3 qualifies as a substitute based on matching core mechanical and electrical parameters, with noted differences in current capacity, voltage rating, and flammability classification that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Altech 40.003 Selection Criteria:

• Applications requiring 300V voltage rating
• Applications requiring UL94 V-0 flammability classification
• Standard 20A current capacity is sufficient
• Preferred when maximum safety margin for voltage and flame resistance is required

TE Connectivity 1776293-3 Selection Criteria:

• Applications with voltage requirements at or below 250V
• Applications where UL94 V-2 flammability rating is acceptable
• Applications requiring current capacity up to 30A
• Preferred when higher current capacity is beneficial and voltage/flammability specifications permit
• Both parts maintain ROHS3 compliance and active production status

The selection between these parts must be based on the specific voltage and flammability requirements of the target application. The TE Connectivity substitute provides superior current handling but operates at reduced voltage and flammability ratings compared to the Altech original.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1776293-3 be used in place of Altech 40.003 in all applications?

A: No. The TE Connectivity part has a 250V voltage rating versus the Altech part's 300V rating, and a UL94 V-2 flammability rating versus UL94 V-0. Substitution is only valid when the application's voltage requirement does not exceed 250V and the flammability specification permits V-2 classification.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts share identical pitch spacing (0.315"/8.00mm), circuit count (3), wire entry configuration (6), and row arrangement (2). Mechanical interchangeability is confirmed for chassis and panel mounting applications.

Q: What is the wire gauge compatibility for both parts?

A: Both the Altech 40.003 and TE Connectivity 1776293-3 accept wire gauges from 12 AWG to 22 AWG, ensuring consistent termination capability across the substitution pair.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both parts are ROHS3 Compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the primary difference in current rating between these parts?

A: The Altech 40.003 is rated for 20A maximum current, while the TE Connectivity 1776293-3 is rated for 30A. The TE Connectivity part provides 50% additional current capacity, which may be advantageous in high-load applications where the voltage and flammability specifications are compatible.

Q: Are there temperature operating range differences?

A: Yes. The Altech 40.003 operates from -30°C to 125°C, while the TE Connectivity 1776293-3 operates from -35°C to 100°C. Application temperature requirements must be verified against the selected part's operating range.
