PS7341CL-1A-A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7341CL-1A-A is a solid state relay (SSR) manufactured by CEL, configured as a single-pole single-throw normally open (SPST-NO) device rated for 120 mA load current across 0–400 V. This component features surface mount packaging in a 6-SMD gull wing configuration with a 1.2 VDC input trigger voltage and 35 Ohms maximum on-state resistance.

The PS7341CL-1A-A carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this SSR relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7341CL-1A-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC and DC switching capability
• Load current rating: 120 mA minimum
• Load voltage range: Must support 0–400 V operation
• Mounting type: Surface mount
• Termination style: Gull wing
• Input voltage compatibility: 1.2 VDC or lower trigger voltage

Allowable Variations:

• On-state resistance: Substitute may be lower (improved performance)
• Load voltage maximum: Substitute may exceed 400 V (backward compatible)
• Input voltage: Substitute may require lower trigger voltage (improved sensitivity)
• Package density: Substitute may use fewer SMD pads if electrical performance is maintained
• Product status: Active status preferred for long-term availability

The AQY210HLA from Panasonic Electric Works meets these substitution criteria and is identified as a direct equivalent for the PS7341CL-1A-A.

Engineering Selection Recommendations

Primary Substitute: AQY210HLA

The AQY210HLA is the recommended substitute for the obsolete PS7341CL-1A-A based on the following engineering factors:

1. Functional Equivalence: Both devices provide SPST-NO switching with 120 mA load current and AC/DC output capability. Input and load voltage specifications are compatible for most applications operating below 350 V.

2. Product Status: The AQY210HLA carries active product status, ensuring continued availability and supply chain support. The PS7341CL-1A-A is obsolete and subject to inventory depletion.

3. Compliance & Certifications: The AQY210HLA is RoHS compliant and REACH unaffected, meeting modern regulatory requirements. Both devices share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications.

4. Performance Improvement: The AQY210HLA exhibits lower on-state resistance (25 Ohms vs. 35 Ohms) and lower input trigger voltage (1.14 VDC vs. 1.2 VDC), providing improved switching efficiency and control margin.

5. Package Consideration: The AQY210HLA uses a 4-SMD package versus the 6-SMD package of the PS7341CL-1A-A. PCB footprint compatibility must be verified during design integration. The 0.300" (7.62 mm) pitch remains identical.

6. Load Voltage Limitation: The AQY210HLA maximum load voltage is 350 V compared to 400 V for the PS7341CL-1A-A. Applications requiring operation above 350 V require design review and alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the AQY210HLA directly replace the PS7341CL-1A-A on existing PCBs?

A: Direct replacement depends on PCB footprint design. The AQY210HLA uses a 4-SMD package while the PS7341CL-1A-A uses a 6-SMD package. Both maintain 0.300" (7.62 mm) pitch spacing. Verify that the PCB footprint accommodates the 4-SMD gull wing configuration before substitution. Adapter solutions or PCB redesign may be required.

Q: What is the impact of the 350 V maximum load voltage on the AQY210HLA versus the 400 V rating of the PS7341CL-1A-A?

A: The AQY210HLA is rated for 0–350 V load operation. Applications requiring switching above 350 V cannot use this substitute. Confirm the maximum load voltage in your application circuit. If operation above 350 V is required, alternative components must be evaluated.

Q: Does the lower on-state resistance of the AQY210HLA (25 Ohms vs. 35 Ohms) affect circuit design?

A: Lower on-state resistance reduces voltage drop across the relay during conduction, resulting in lower power dissipation and improved efficiency. This is a performance improvement that does not negatively impact circuit compatibility. Existing circuit designs will function correctly with the AQY210HLA.

Q: Are there compliance or regulatory differences between the PS7341CL-1A-A and AQY210HLA?

A: The AQY210HLA is RoHS compliant and REACH unaffected. The PS7341CL-1A-A is REACH affected. Both share identical ECCN and HTSUS classifications. For applications subject to RoHS or REACH regulations, the AQY210HLA is the preferred choice.

Q: What is the input voltage trigger requirement for the AQY210HLA?

A: The AQY210HLA requires 1.14 VDC input trigger voltage, which is lower than the PS7341CL-1A-A requirement of 1.2 VDC. This lower trigger voltage provides improved control margin and sensitivity. Existing control circuits designed for 1.2 VDC will operate reliably with the AQY210HLA.

Q: Is the AQY210HLA available in the same packaging format as the PS7341CL-1A-A?

A: Both devices use surface mount gull wing termination with 0.300" (7.62 mm) pitch. The AQY210HLA is supplied in tube packaging, while the PS7341CL-1A-A packaging format is not specified in available data. The 4-SMD versus 6-SMD package difference requires footprint verification.
