Key Parameters

Substitute Part Grouping Explanation

Substitution for the PLA10AS2030R5R2B is determined by the following critical parameters:

• Filter Type: Power Line (all substitutes must be power line common mode chokes)
• Number of Lines: 2-line configuration (mandatory for EMI filtering in dual-conductor applications)
• Mounting Type: Through Hole (mechanical compatibility with existing PCB layouts)
• Package / Case: Vertical, 4 PC Pin (physical and electrical interface requirement)
• Current Rating: Minimum 500mA (electrical load capacity)
• DC Resistance: Maximum 1.8Ohm (power dissipation and insertion loss)
• Voltage Rating: Minimum 250V DC or AC (electrical safety margin)

Three substitute parts meet these criteria with varying performance characteristics and availability status.

Parameter Comparison

Engineering Selection Recommendations

7414-RC (Bourns Inc.): Active product status with higher current rating (600mA) and lower DC resistance (1.11Ohm). ROHS3 compliant. Suitable for applications requiring improved thermal performance and extended temperature range (-55°C ~ 105°C). Voltage rating specified as 250V AC.

ALFT-03A-4 (Abracon LLC): Active product status with matched current rating (500mA) and DC resistance (1.2Ohm) closest to the original specification. ROHS3 compliant. Operating temperature range (-25°C ~ 85°C) aligns with the original part's lower bound. Voltage rating specified as 250V DC.

SS21V-250015 (KEMET): Active product status with significantly higher current capacity (2.5A) and substantially lower DC resistance (100mOhm). ROHS3 compliant. Suitable for applications requiring higher current handling and reduced power dissipation. Operating temperature range extends to 120°C. Voltage rating specified as 250V AC. Moisture sensitivity level not applicable.

All three substitutes maintain the 2-line, through-hole, vertical 4-pin package configuration and power line filter type required for direct mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7414-RC replace the PLA10AS2030R5R2B in all applications?

A: The 7414-RC meets the minimum electrical and mechanical requirements. The higher current rating (600mA vs. 500mA) and lower DC resistance (1.11Ohm vs. 1.8Ohm) provide improved performance margins. Verify that the extended temperature range (-55°C ~ 105°C) and AC voltage rating specification are compatible with your circuit design.

Q: What is the primary difference between ALFT-03A-4 and the original part?

A: The ALFT-03A-4 maintains the same current rating (500mA) and similar DC resistance (1.2Ohm vs. 1.8Ohm). The main differences are the active product status, ROHS3 compliance, and slightly extended operating temperature range to 85°C. Physical dimensions are larger (23.90mm L x 18.00mm W vs. 18.00mm L x 16.00mm W).

Q: When should SS21V-250015 be selected over other substitutes?

A: Select SS21V-250015 when the application requires higher current capacity (2.5A) or significantly reduced power dissipation (100mOhm DCR). This part is suitable for designs with higher thermal constraints or increased current demands beyond the original 500mA specification.

Q: Are all substitutes through-hole mounted with the same pin configuration?

A: Yes. All three substitutes maintain the vertical, 4-pin through-hole package configuration, ensuring direct mechanical compatibility with existing PCB layouts designed for the PLA10AS2030R5R2B.

Q: Do all substitutes meet RoHS compliance requirements?

A: All three active substitutes are ROHS3 compliant. The original PLA10AS2030R5R2B does not specify RoHS status due to its obsolete classification.

Q: What voltage ratings should be verified during substitution?

A: The original part specifies 250V DC. Substitutes specify either 250V DC (ALFT-03A-4) or 250V AC (7414-RC, SS21V-250015). Confirm that your circuit design voltage requirements align with the selected substitute's voltage rating specification.
