Molex 0382110118 Equivalent & Substitute Parts

Part Overview

The Molex 0382110118 is an 18-circuit barrier block connector with 0.563" (14.30mm) pitch, rated for 30A at 300V. This component is classified as obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and system upgrades. The barrier block design with dual-wall construction and flange mounting provides reliable electrical isolation and mechanical stability in industrial control and power distribution applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0382110118 is determined by strict equivalence across the following critical parameters:

Circuit Configuration: 18 circuits with 0.563" (14.30mm) pitch and 2-row arrangement
Electrical Ratings: 30A current capacity and 300V voltage rating
Termination Method: Screw-based top termination with closed bottom termination
Mechanical Design: Dual-wall barrier construction with flange for chassis/panel mounting
Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The TE Connectivity AMP Connectors part 1-1546310-8 meets all substitution criteria. Both components share identical circuit count, pitch, electrical ratings, termination style, and barrier configuration. Differences in wire gauge acceptance range (10-22 AWG vs. 10-18 AWG), insulation material (PBT vs. Phenolic), operating temperature range, and terminal finish do not prevent functional substitution in applications designed for the original part.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1546310-8 is a direct functional substitute for the obsolete Molex 0382110118. Both components maintain identical electrical and mechanical specifications across all critical parameters required for barrier block terminal applications.

Product Status Consideration: The Molex part is obsolete, while the TE Connectivity equivalent is active production. Selection of the active part ensures long-term availability and supply chain continuity.

Compliance Alignment: Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial control and power distribution systems.

Physical Compatibility: Identical pitch (0.563"), circuit count (18), row configuration (2), and flange mounting design ensure direct mechanical fit in existing PCB layouts and chassis assemblies.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1546310-8 be used as a direct replacement for the Molex 0382110118?

A: Yes. Both components share identical circuit configuration, electrical ratings (30A, 300V), pitch spacing, termination method, and mounting design. The TE part is mechanically and electrically compatible for direct substitution.

Q: What is the difference in wire gauge acceptance between these parts?

A: The Molex 0382110118 accepts 10-18 AWG wire, while the TE Connectivity 1-1546310-8 accepts 10-22 AWG wire. The TE part accommodates a wider gauge range, making it suitable for applications using either specification.

Q: Are there differences in insulation material between these parts?

A: Yes. The Molex part uses Phenol Formaldehyde (Phenolic) insulation, while the TE part uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and do not affect functional compatibility in standard applications.

Q: What is the operating temperature range for each part?

A: The Molex 0382110118 operates to 150°C. The TE Connectivity 1-1546310-8 operates from -40°C to 120°C. Application requirements determine which temperature range is appropriate.

Q: Do both parts have the same terminal screw finish?

A: No. The Molex part features Zinc with Clear Chromate finish, while the TE part features Nickel finish. Both finishes provide corrosion resistance suitable for industrial environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0382110118 and TE Connectivity 1-1546310-8 are ROHS3 compliant.
