Key Parameters

Substitute Part Grouping Explanation

Substitution for the PLA10AS2230R4D2B is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration
• Mounting Type: Must be through-hole
• Package Configuration: Must be vertical, 4-pin package
• Current Rating: Substitute must support minimum 400mA
• DC Resistance: Substitute DCR must not exceed 2.7Ohm to maintain equivalent filtering performance
• Voltage Rating: Substitute must support minimum 250V DC or equivalent AC rating
• Filter Type: Must be power line common mode choke

The identified substitutes meet these core electrical and mechanical requirements while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

7414-RC (Bourns Inc.): This substitute provides superior current handling at 600mA versus the original 400mA specification, with significantly lower DC resistance of 1.11Ohm compared to 2.7Ohm. The part maintains 250V AC voltage rating and features an extended operating temperature range of -55°C to 105°C. Product status is active with ROHS3 compliance. Physical dimensions are marginally larger (19.00mm x 17.00mm x 21.00mm maximum height), requiring verification of PCB layout compatibility.

ALFT-03A-3 (Abracon LLC): This substitute matches the original 400mA current rating with improved DC resistance of 1.5Ohm. It maintains 250V DC voltage rating and operates across -25°C to 85°C. Product status is active with ROHS3 compliance. Physical dimensions are larger (23.90mm x 18.00mm x 21.60mm maximum height), requiring PCB layout verification for footprint accommodation.

Both substitutes are active products with established supply chains, addressing the obsolescence of the original PLA10AS2230R4D2B component.

Frequently Asked Questions (FAQ)

Q: Can the 7414-RC substitute the PLA10AS2230R4D2B in all applications?

A: The 7414-RC meets the core substitution criteria: 2-line configuration, through-hole mounting, vertical 4-pin package, and 250V voltage rating. The higher current rating (600mA) and lower DC resistance (1.11Ohm) provide improved performance margins. Physical dimensions are slightly larger; verify PCB layout compatibility before implementation.

Q: What is the primary difference between the two substitute options?

A: The 7414-RC offers higher current capacity (600mA) and lower DC resistance (1.11Ohm), while the ALFT-03A-3 matches the original current rating (400mA) with moderate resistance reduction (1.5Ohm). The 7414-RC has a wider operating temperature range (-55°C to 105°C). The ALFT-03A-3 has larger physical dimensions. Selection depends on thermal requirements and available PCB space.

Q: Are the substitute parts RoHS compliant?

A: Both substitute parts are ROHS3 compliant. The original PLA10AS2230R4D2B does not specify RoHS status.

Q: Will the larger physical dimensions of the substitutes affect my design?

A: The ALFT-03A-3 has the largest footprint (23.90mm x 18.00mm). The 7414-RC dimensions (19.00mm x 17.00mm) are closer to the original (18.00mm x 16.00mm). Verify available PCB space and component placement constraints before selection.

Q: What is the inductance specification for the substitute parts?

A: The 7414-RC is specified at 20 mH @ 1 kHz. The ALFT-03A-3 is specified at 26 mH @ 1 kHz. The original PLA10AS2230R4D2B does not provide inductance data in the available parameters.
