PS710CL2-1A-A Equivalent & Substitute Parts

Part Overview

The PS710CL2-1A-A is a solid-state relay (SSR) manufactured by CEL, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switching device. This component provides 2A load switching capability across a 0V to 60V DC/AC output range with a 1.2VDC control input. The PS710CL2-1A-A is classified as obsolete, requiring identification of functionally compatible alternatives for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The AQY272A from Panasonic Electric Works qualifies as a substitute for the PS710CL2-1A-A based on the following substitution criteria:

Critical Parameters (Must Match):

• Circuit configuration: SPST-NO (1 Form A)
• Output capability: AC and DC switching
• Load current rating: 2 A
• Load voltage range: 0 V ~ 60 V
• Mounting type: Surface Mount
• Termination style: Gull Wing

Compatible Deviations (Within Electrical Tolerance):

• Input voltage: 1.16VDC (substitute) vs. 1.2VDC (original) — operationally compatible
• On-state resistance: 180 mOhms (substitute) vs. 150 mOhms (original) — within acceptable switching performance
• Package footprint: 4-SMD (substitute) vs. 6-SMD (original) — functionally equivalent, potentially board-space favorable

Parameter Comparison

Engineering Selection Recommendations

The AQY272A is the primary substitute for the obsolete PS710CL2-1A-A due to product lifecycle considerations. The original PS710CL2-1A-A has reached end-of-life status, and the AQY272A provides equivalent functional performance across all critical switching parameters.

Regulatory Compliance Advantage: The AQY272A offers improved compliance posture with ROHS3 certification and REACH Unaffected status, whereas the PS710CL2-1A-A carries REACH Affected classification. For applications requiring updated regulatory compliance documentation, the AQY272A is the appropriate selection.

Availability and Supply Chain: The AQY272A is designated as active product status, ensuring continued availability and supplier support. The PS710CL2-1A-A, despite current inventory (831 Pcs), is obsolete and subject to discontinuation.

Electrical Performance: The AQY272A operates at a marginally lower input voltage (1.16VDC vs. 1.2VDC) and exhibits slightly higher on-state resistance (180 mOhms vs. 150 mOhms). These differences remain within acceptable operating parameters for SPST-NO 2A relay applications.

Frequently Asked Questions (FAQ)

Q: Can the AQY272A be used directly in place of the PS710CL2-1A-A without board layout modifications?

A: The AQY272A has a 4-SMD footprint compared to the PS710CL2-1A-A's 6-SMD footprint. PCB pad layouts must be verified for compatibility. Both components use identical termination style (Gull Wing) and identical lead spacing (0.300", 7.62mm), but footprint area differs. Board-level redesign may be required.

Q: What is the impact of the on-state resistance difference (150 mOhms vs. 180 mOhms) on circuit operation?

A: The 30 mOhms difference results in increased voltage drop across the relay during conduction. For a 2A load, this represents an additional 60 mV drop (0.030 Ω × 2 A). System power budgets and thermal management must account for this increased on-state losses.

Q: Are the input control voltage specifications compatible?

A: Yes. The AQY272A operates at 1.16VDC input, compared to the PS710CL2-1A-A at 1.2VDC. This 40 mV difference is operationally compatible with standard microcontroller and signal conditioning circuits. Standard 3.3V and 5V logic signaling remains compatible.

Q: What packaging format is the AQY272A available in?

A: The AQY272A is supplied in Tube packaging. The PS710CL2-1A-A packaging format is not specified in available documentation. Verify packaging requirements for downstream assembly processes.

Q: Does the AQY272A support both AC and DC load switching like the PS710CL2-1A-A?

A: Yes. The AQY272A is rated for both AC and DC output switching across the 0V to 60V load voltage range, identical to the PS710CL2-1A-A specifications.
