Key Parameters

Substitute Part Grouping Explanation

Substitution of the Eaton A207306R36 is based on strict alignment of the following critical parameters:

Critical Matching Parameters:

• Terminal block type must be barrier block
• Circuit count must equal 6
• Pitch spacing must be 0.375" (9.53mm)
• Voltage rating must be 300V or higher
• Wire gauge range must accommodate 12-22 AWG
• Top termination must be screw-type
• Bottom termination must be PC pin configuration
• Mounting must support through-hole, right-angle installation
• Barrier construction must be dual-wall (2 Wall)

Important Compatibility Parameters:

• Operating temperature range must encompass -40°C to 105°C
• Material flammability rating must meet UL94 V-0 standard

The Curtis Industries T38170-06-0 satisfies all critical matching parameters and important compatibility requirements, establishing it as a functional equivalent for the obsolete Eaton component.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries T38170-06-0 serves as the functional equivalent for the obsolete Eaton A207306R36 based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical voltage ratings (300V), wire gauge specifications (12-22 AWG), and dual-wall barrier construction. The T38170-06-0 current rating of 20A is lower than the original 30A specification; applications requiring the full 30A capacity must evaluate alternative sources.

Mechanical Compatibility: Pitch spacing (0.375"), circuit count (6), and mounting configuration (through-hole, right-angle) are identical, ensuring direct PCB layout compatibility without redesign.

Compliance Status: Both components achieve UL94 V-0 flammability rating. The Curtis Industries part carries active product status with RoHS3 compliance and REACH unaffected designation, providing supply chain continuity and regulatory alignment for new designs.

Material Considerations: The Curtis Industries substitute uses polypropylene insulation with nickel-plated terminal screws, compared to thermoplastic insulation and zinc-plated screws in the original. Both material systems meet the specified flammability standard.

Temperature Range: The Curtis Industries component specifies 105°C maximum operating temperature, which covers the upper limit of the original -40°C to 105°C range. Applications requiring the full lower temperature specification (-40°C) should confirm compatibility with the substitute's actual minimum operating temperature.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries T38170-06-0 directly replace the Eaton A207306R36 in existing designs?

A: Direct replacement is possible for applications where the 20A current rating of the Curtis Industries component meets system requirements. The 0.375" pitch, 6-circuit configuration, 300V voltage rating, and through-hole mounting are identical. Applications requiring the original 30A capacity must source alternative components.

Q: What is the significance of the pitch specification in barrier block selection?

A: Pitch (0.375" or 9.53mm) defines the center-to-center spacing between circuits and determines PCB layout compatibility. Substitutes must match the original pitch exactly to ensure proper mounting without PCB redesign. Both the Eaton and Curtis Industries components share identical 0.375" pitch.

Q: How do the insulation materials differ between these components?

A: The Eaton A207306R36 uses thermoplastic insulation, while the Curtis Industries T38170-06-0 uses polypropylene (PP). Both materials achieve UL94 V-0 flammability rating. Polypropylene offers chemical resistance and dimensional stability; thermoplastic provides general-purpose performance. Selection depends on specific environmental exposure requirements.

Q: What does the dual-wall (2 Wall) barrier construction provide?

A: Dual-wall barrier construction creates electrical isolation between adjacent circuits, preventing cross-talk and improving safety margins in high-voltage applications. Both components feature this construction, maintaining equivalent electrical isolation performance.

Q: Are there packaging differences between the original and substitute?

A: The Eaton A207306R36 is packaged in standard format with 655 pieces in stock. The Curtis Industries T38170-06-0 is supplied in bulk packaging with 968 pieces available. Bulk packaging typically offers cost advantages for volume applications.

Q: What compliance certifications should be verified for new designs?

A: Both components meet UL94 V-0 flammability requirements. The Curtis Industries T38170-06-0 carries RoHS3 compliance and REACH unaffected status, making it suitable for applications with regulatory compliance requirements. The Eaton component's obsolete status limits its use in new designs requiring current compliance documentation.

Q: How does the current rating difference affect component selection?

A: The Eaton A207306R36 supports 30A per circuit, while the Curtis Industries T38170-06-0 supports 20A per circuit. Applications operating at or below 20A per circuit can use the substitute without derating. Higher-current applications must identify alternative sources or implement circuit-level current management.
