Key Parameters

Substitute Part Grouping Explanation

Substitution of the A201404RC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal Block Type: Barrier Block
• Number of Circuits: 4
• Pitch: 0.375" (9.53mm)
• Number of Rows: 1
• Voltage Rating: 300V
• Wire Gauge: 12-22 AWG
• Top Termination: Screws
• Bottom Termination: Solder Turret, Insulated
• Barrier Type: 2 Wall (Dual)
• Mounting Type: Chassis, Panel
• Material Flammability Rating: UL94 V-0

The T38320-04-0 manufactured by Curtis Industries meets all mandatory matching parameters. This part is classified as active product status with current availability, providing a direct functional equivalent for the obsolete A201404RC.

Parameter Comparison

Engineering Selection Recommendations

The T38320-04-0 serves as a direct functional equivalent for the obsolete A201404RC across all critical mechanical and electrical parameters. Both components share identical circuit count, pitch spacing, voltage rating, wire gauge compatibility, and termination methods.

Current Rating Consideration: The T38320-04-0 is rated for 20A maximum current, compared to the A201404RC rating of 30A. Circuit designs operating at currents between 20A and 30A require evaluation against actual application requirements.

Compliance Advantage: The T38320-04-0 holds ROHS3 compliance status, whereas the A201404RC is non-compliant. For applications subject to RoHS regulations, the T38320-04-0 provides regulatory alignment.

Product Availability: The T38320-04-0 maintains active product status with documented inventory availability, eliminating obsolescence risk associated with the A201404RC.

Frequently Asked Questions (FAQ)

Q: Can the T38320-04-0 directly replace the A201404RC in existing designs?

A: The T38320-04-0 matches all critical mechanical and electrical parameters including circuit count, pitch, voltage rating, wire gauge, and termination type. Direct mechanical and electrical substitution is supported. Current rating differences must be evaluated for specific applications.

Q: What is the significance of the current rating difference between these parts?

A: The A201404RC is rated for 30A maximum current, while the T38320-04-0 is rated for 20A. Applications requiring currents exceeding 20A must be assessed against actual circuit requirements. Applications operating at 20A or below are unaffected by this difference.

Q: Are there packaging differences between these parts?

A: The A201404RC is supplied in standard packaging, while the T38320-04-0 is supplied in bulk packaging. Both are suitable for the same mounting applications.

Q: Does the insulation material difference affect compatibility?

A: The A201404RC uses thermoplastic insulation, while the T38320-04-0 uses polypropylene (PP) insulation. Both materials achieve UL94 V-0 flammability rating and are compatible with the specified operating temperature range and voltage rating.

Q: What is the advantage of selecting the T38320-04-0 for new designs?

A: The T38320-04-0 provides active product status, eliminating obsolescence concerns. ROHS3 compliance supports regulatory requirements in jurisdictions with RoHS mandates. Documented inventory availability ensures supply chain continuity.
