AQV253 Equivalent & Substitute Parts

Part Overview

The AQV253 is a solid-state relay (SSR) manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQV series. This SPST-NO (1 Form A) device operates as a 6-DIP through-hole component with a 200 mA load capacity across 0–250 V AC/DC applications. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AQV253 are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Termination style: PC Pin
• Output type: AC, DC
• Product status: Active
• RoHS compliance: ROHS3 Compliant

Electrical Performance Parameters (Allowed Variation):

• Input voltage: 1.14 VDC (±0.13 VDC tolerance acceptable)
• Load voltage range: 0 V ~ 250 V (or 0 V ~ 200 V minimum)
• Load current: 200 mA minimum (higher ratings acceptable)
• On-state resistance: 8 Ohms maximum (lower values acceptable)

Three substitute parts meet these criteria: LCA127 (Littelfuse), LH1510AT (Vishay Semiconductor Opto Division), and PLA150 (IXYS Integrated Circuits Division).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory and compliance profile of the AQV253.

LCA127 (Littelfuse): Maintains identical load current (200 mA) and load voltage range (0–250 V). Input voltage is 1.2 VDC, within acceptable tolerance. On-state resistance is 10 Ohms, slightly higher than the AQV253. This part is suitable for direct substitution in applications where the 2 Ohm resistance increase is acceptable.

LH1510AT (Vishay Semiconductor Opto Division): Maintains identical load current (200 mA) and circuit configuration. Load voltage range is 0–200 V, which is 50 V lower than the AQV253. Input voltage is 1.27 VDC, within acceptable tolerance. On-state resistance is 15 Ohms, significantly higher than the AQV253. This part is suitable only for applications where the maximum load voltage does not exceed 200 V and where the higher on-state resistance does not impact circuit performance.

PLA150 (IXYS Integrated Circuits Division): Exceeds the AQV253 load current specification at 250 mA, providing additional margin. Load voltage range matches at 0–250 V. Input voltage is 1.2 VDC, within acceptable tolerance. On-state resistance is 7 Ohms, lower than the AQV253, providing improved performance. This part is suitable for direct substitution and offers enhanced electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the LH1510AT replace the AQV253 in all applications?

A: The LH1510AT is suitable only for applications where the maximum load voltage does not exceed 200 V. The AQV253 supports 0–250 V; the LH1510AT supports 0–200 V. If your application requires operation above 200 V, the LH1510AT is not compatible.

Q: What is the significance of on-state resistance differences?

A: On-state resistance affects voltage drop across the relay during conduction. The AQV253 has 8 Ohms maximum; LCA127 has 10 Ohms; LH1510AT has 15 Ohms; PLA150 has 7 Ohms. Higher resistance increases power dissipation and voltage drop. For low-current or low-power applications, these differences may be negligible. For high-current or precision applications, verify that the substitute part's resistance does not exceed circuit requirements.

Q: Are all substitute parts pin-compatible with the AQV253?

A: Yes. All substitute parts use the 6-DIP (0.300", 7.62mm) package with PC pin termination and through-hole mounting, ensuring mechanical and electrical pin compatibility on standard PCBs.

Q: Do all substitute parts meet the same compliance standards as the AQV253?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification, matching the AQV253 regulatory profile.

Q: Which substitute part offers the best performance upgrade?

A: The PLA150 provides the lowest on-state resistance (7 Ohms versus 8 Ohms) and the highest load current rating (250 mA versus 200 mA), while maintaining the full 0–250 V load voltage range. It is suitable for direct substitution with performance enhancement.

Q: Can I use a substitute part with higher load current rating in a 200 mA application?

A: Yes. The PLA150 is rated for 250 mA and can be used in applications requiring 200 mA. Higher current ratings provide design margin and do not create compatibility issues in lower-current applications.
