Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0382190253 is determined by strict equivalence across the following critical parameters:

• Terminal block type: Barrier block configuration
• Circuit count: 4 circuits
• Pitch specification: 0.563" (14.30mm)
• Row configuration: 2 rows
• Electrical ratings: 30A current, 300V voltage
• Termination method: Screw-based top termination with closed bottom
• Barrier configuration: 2-wall (dual) barrier design
• Mounting compatibility: Chassis and panel mounting capability

The TE Connectivity AMP Connectors part 1546310-4 meets all these core substitution criteria. While this substitute introduces enhanced specifications in wire gauge range (10-22 AWG versus 10-18 AWG), operating temperature range (-40°C to 120°C), material specifications (PBT insulation, nickel-plated steel screws), and flammability rating (UL94 V-0), these represent functional improvements rather than incompatibilities. The substitute maintains identical mechanical and electrical interface characteristics, ensuring direct form-fit-function replacement capability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1546310-4 is the primary substitute for the obsolete Molex 0382190253. Selection is justified on the following engineering grounds:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and identical ECCN/HTSUS classifications, ensuring regulatory equivalence for procurement and deployment.

Product Lifecycle: The TE Connectivity part carries active product status with confirmed inventory availability (3603 units), whereas the Molex component is obsolete. For new designs or system replenishment, the active substitute eliminates supply chain risk.

Functional Equivalence: Identical electrical ratings (30A, 300V), mechanical pitch (0.563"), circuit configuration (4-circuit, 2-row), and termination method (screw-based) ensure direct replacement without circuit redesign or mechanical rework.

Enhanced Specifications: The substitute provides extended wire gauge accommodation (10-22 AWG), defined operating temperature range (-40°C to 120°C), specified insulation material (PBT), and UL94 V-0 flammability rating. These enhancements represent functional improvements that do not compromise backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1546310-4 directly replace the Molex 0382190253 in existing assemblies?

A: Yes. Both components share identical pitch (0.563"), circuit count (4), row configuration (2), electrical ratings (30A/300V), and screw termination method. Mechanical and electrical interfaces are equivalent, enabling direct substitution without assembly modification.

Q: What is the significance of the wire gauge difference (10-18 AWG versus 10-22 AWG)?

A: The substitute accepts a broader wire gauge range. Existing installations using 10-18 AWG wire remain fully compatible. The extended range to 22 AWG provides additional flexibility for future applications but does not affect current designs.

Q: Why is the Molex part listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The TE Connectivity substitute maintains active production status with established supply channels, making it the recommended choice for ongoing procurement.

Q: Are there compliance or certification differences between these components?

A: Both components are ROHS3 compliant with identical ECCN and HTSUS classifications. The TE Connectivity part includes specified material certifications (PBT insulation, UL94 V-0 flammability rating) and operating temperature range, providing enhanced documentation for regulated applications.

Q: What inventory considerations apply to this substitution?

A: The Molex 0382190253 has 846 units in stock (obsolete status). The TE Connectivity 1546310-4 has 3603 units available with active product status, ensuring long-term supply availability for production and maintenance requirements.
