PS7214-1A Solid State Relay: Equivalent & Substitute Parts

Part Overview

The PS7214-1A is a Solid State SPST-NO (1 Form A) relay manufactured by CEL in a 4-SOP surface mount package. This component is rated for 400 mA load current at 0–100 V with a 1.2 VDC input trigger and 1.2 Ohms maximum on-state resistance. The PS7214-1A is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Panasonic Electric Works PhotoMOS™ series relays provide active, RoHS3-compliant alternatives that maintain functional compatibility within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7214-1A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Circuit configuration: SPST-NO (1 Form A) maintained across all substitutes
• Output type: AC and DC switching capability required
• Load voltage range: 0–100 V minimum (or compatible subset)
• Input voltage: 1.14–1.25 VDC acceptable range for trigger activation
• Mounting type: Surface mount with gull wing termination
• Package compatibility: 4-SOP or 6-SOP form factors

Substitution Logic: The three Panasonic Electric Works PhotoMOS™ alternatives (AQV215S, AQY215S, AQY225R2S) satisfy the core SPST-NO switching function and load voltage requirements. However, load current ratings vary: AQV215S (300 mA), AQY215S (250 mA), and AQY225R2S (150 mA). Selection depends on application current requirements. All substitutes are active products with RoHS3 compliance, addressing the obsolescence and regulatory status of the PS7214-1A.

Parameter Comparison

Engineering Selection Recommendations

AQV215S Selection Criteria: The AQV215S is the highest-current substitute at 300 mA, suitable for applications requiring load currents between 300–400 mA. This part maintains the 0–100 V load voltage range and operates with 1.14 VDC input. The 6-SOP package requires PCB layout adjustment from the original 4-SOP footprint. RoHS3 compliance and active product status support long-term supply continuity.

AQY215S Selection Criteria: The AQY215S accommodates load currents up to 250 mA in a 4-SMD package compatible with 4-SOP PCB layouts. Input voltage of 1.25 VDC aligns closely with the PS7214-1A specification. This part is suitable for applications with reduced current requirements and provides RoHS3 compliance with active manufacturing status.

AQY225R2S Selection Criteria: The AQY225R2S is rated for 150 mA maximum load current and operates within a 0–80 V load voltage range. This substitute is appropriate only for applications with load voltages not exceeding 80 V and currents below 150 mA. The 4-SOP package matches the original PS7214-1A footprint. RF output capability provides additional functionality for specialized switching applications. RoHS3 compliance and active status ensure supply availability.

Regulatory Compliance: All three substitutes are RoHS3 compliant and REACH unaffected, addressing the non-compliant status of the obsolete PS7214-1A. Selection should prioritize active product status and regulatory alignment with target application requirements.

Frequently Asked Questions (FAQ)

Q: Can the AQV215S directly replace the PS7214-1A on existing PCBs?

A: The AQV215S uses a 6-SOP package versus the PS7214-1A's 4-SOP package. PCB footprint modification is required. Pin configuration and electrical function are compatible within the specified load current range (300 mA maximum).

Q: Which substitute is best for 400 mA load current applications?

A: No substitute maintains the full 400 mA rating of the PS7214-1A. The AQV215S provides the highest current capacity at 300 mA. Applications requiring 400 mA must either use alternative relay architectures or reduce load current to 300 mA maximum.

Q: Are all substitutes compatible with 100 V load voltage?

A: The AQV215S and AQY215S support 0–100 V load voltage ranges. The AQY225R2S is limited to 0–80 V. Verify application load voltage requirements before selecting AQY225R2S.

Q: What is the impact of higher on-state resistance in substitute parts?

A: The PS7214-1A has 1.2 Ohms maximum on-state resistance. Substitutes range from 4 Ohms (AQV215S, AQY215S) to 15 Ohms (AQY225R2S). Higher resistance increases voltage drop across the relay and heat dissipation. Verify thermal and voltage drop performance in target applications.

Q: Do all substitutes support both AC and DC output switching?

A: Yes. AQV215S and AQY215S support AC and DC output. AQY225R2S supports AC, DC, and RF output, providing additional capability for RF switching applications.

Q: What is the input voltage tolerance for trigger activation?

A: PS7214-1A requires 1.2 VDC input. Substitutes operate at 1.14 VDC (AQV215S, AQY225R2S) or 1.25 VDC (AQY215S). All values fall within typical 1.2 VDC ±10% tolerance windows for solid state relay trigger circuits.

Q: Are the Panasonic substitutes available in the same packaging as the original?

A: AQY215S and AQY225R2S use 4-SOP or 4-SMD packages compatible with the PS7214-1A 4-SOP footprint. AQV215S uses a 6-SOP package requiring PCB modification. Verify packaging compatibility with existing designs before component selection.
