Substitute Part Grouping Explanation

Substitution eligibility for the OSTVI044150 is determined by strict alignment across the following critical parameters:

Position Count & Pitch: Substitute must maintain 4 positions at 0.295" (7.50mm) pitch to ensure PCB footprint compatibility
Electrical Ratings: Minimum 16A current and 300V voltage ratings required
Mounting Configuration: Through-hole vertical orientation with board mounting mandatory
Termination Method: Screw-based rising cage clamp termination required
Screw Specification: M3 thread size required for mechanical compatibility
Temperature Range: Operating range of -30°C to 105°C or broader required
Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The ED360/4 meets all substitution criteria across these parameters, establishing it as a direct equivalent for the obsolete OSTVI044150.

Engineering Selection Recommendations

The ED360/4 is the qualified substitute for the obsolete OSTVI044150 based on the following engineering criteria:

Regulatory & Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical & Mechanical Equivalence: The ED360/4 preserves all critical electrical parameters (16A, 300V) and mechanical specifications (4-position, 7.5mm pitch, M3 screw thread, through-hole mounting) required for direct PCB footprint and circuit compatibility.

Product Status Advantage: The ED360/4 carries Active product status with confirmed inventory availability (693 pcs), providing supply chain security for new designs and ongoing production support.

Wire Gauge Consideration: The ED360/4 supports 12-22 AWG wire gauge, which encompasses the majority of the OSTVI044150 range (12-28 AWG). Applications requiring 24-28 AWG termination should verify wire gauge compatibility during design transition.

Frequently Asked Questions (FAQ)

Q: Can ED360/4 be used as a direct replacement for OSTVI044150 in existing designs?

A: Yes. The ED360/4 maintains identical PCB footprint, pitch spacing, electrical ratings, and screw termination specifications. No PCB layout modifications are required for substitution.

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

A: The OSTVI044150 accepts 12-28 AWG wire, while the ED360/4 accepts 12-22 AWG wire. The ED360/4 covers the standard wire gauge range for this terminal block class. If your application uses 24-28 AWG conductors, verify that the ED360/4 cage clamp mechanism accommodates your specific wire diameter before implementation.

Q: Are the housing materials functionally equivalent?

A: Yes. The OSTVI044150 uses thermoplastic housing, while the ED360/4 uses polyamide (PA) nylon. Both materials provide equivalent electrical insulation, mechanical strength, and thermal stability across the -30°C to 105°C operating range. Material selection does not affect electrical performance or compatibility.

Q: Does the ED360/4 maintain the same torque specification?

A: The screw torque differs slightly: OSTVI044150 specifies 0.4 Nm (3.5 Lb-In), while ED360/4 specifies 0.5 Nm (4.4 Lb-In). Both values fall within standard M3 screw assembly practice. Use the ED360/4 torque specification (0.5 Nm) when terminating wires to this substitute component.

Q: Is the ED360/4 available in the same packaging as the OSTVI044150?

A: The OSTVI044150 packaging is not specified in available data. The ED360/4 is supplied in Bulk packaging. Confirm packaging requirements with your procurement process if specific packaging formats are required.

Q: What compliance certifications apply to the ED360/4?

A: The ED360/4 maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the OSTVI044150. Both components are classified under ECCN EAR99 and HTSUS 8536.90.4000.
