PS7341L-1A Equivalent & Substitute Parts

Part Overview

The PS7341L-1A is a solid-state relay (SSR) manufactured by CEL, configured as SPST-NO (1 Form A) with a 6-SMD gull wing package. The device is rated for 150 mA load current at 0–400 V AC/DC output with 1.2 VDC input control voltage and 30 Ohms maximum on-state resistance. This part carries an obsolete product status with RoHS non-compliant designation. Due to the obsolete status and limited availability for long-term supply chain assurance, equivalent substitute parts are necessary to ensure continued system functionality and compliance with current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following key parameters: circuit configuration (SPST-NO or SPST-NC), output voltage range (minimum 0–400 V requirement), load current capacity (minimum 150 mA requirement), input voltage compatibility (1.14 VDC or lower control voltage), mounting type (surface mount), termination style (gull wing), and package footprint compatibility.

Primary substitutes maintain identical or superior electrical specifications within the 6-SMD package form factor. The AQV214EHA and AQV214HA from Panasonic Electric Works PhotoMOS™ AQV series are direct pin-compatible replacements with active product status and RoHS compliance. Additional substitutes from the PhotoMOS™ AQW and AQY series provide alternative package configurations (8-SMD and 4-SMD respectively) for circuit designs with flexibility in board layout. The AQY414EHA represents a functionally different substitute with SPST-NC (1 Form B) circuit configuration and is suitable only for applications requiring normally-closed relay behavior.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring pin-compatible replacement within existing 6-SMD footprints and maximum performance retention, AQV214EHA and AQV214HA are the primary selections. Both maintain SPST-NO circuit configuration, support 0–400 V output voltage operation, and provide active product status with RoHS compliance certifications. AQV214EHA offers ROHS3 compliance and is recommended for design implementations subject to strict environmental standards.

For load current requirements less demanding than 150 mA, AQV210EHA provides equivalent functionality with 0–350 V voltage capability and 130 mA current rating while maintaining active product status and ROHS3 compliance within the identical 6-SMD package form factor.

For applications with board layout flexibility, AQY214EHA offers a compact 4-SMD package alternative with active status and ROHS3 compliance, rated for 0–400 V output at 120 mA load current. AQW214EHA provides a dual-channel 8-SMD configuration supporting 0–400 V output at 100 mA per channel when SPST-NO functionality is required across two independent circuits.

AQY414EHA substitution is limited to applications requiring SPST-NC (normally-closed) relay operation. This part differs from the PS7341L-1A in circuit configuration and is not suitable for direct functional replacement in standard SPST-NO applications.

Frequently Asked Questions (FAQ)

Q: Can AQV214EHA replace PS7341L-1A in existing designs? A: AQV214EHA is physically and functionally compatible as a pin-for-pin replacement within the same 6-SMD gull wing package footprint. Output voltage range (0–400 V) and input voltage control (1.14 VDC) are compatible. Load current capacity is 120 mA versus the original 150 mA specification; verify system load requirements do not exceed this rating.

Q: What is the difference between AQV214EHA and AQV214HA? A: Both parts provide identical electrical specifications (SPST-NO circuit, 0–400 V output, 120 mA load current, 6-SMD package). AQV214EHA carries ROHS3 compliance designation, while AQV214HA carries standard RoHS compliance. Selection depends on regulatory requirements for your application.

Q: Why do AQW and AQY series substitutes have different load current ratings? A: AQW and AQY series employ different internal architectures and package densities. AQW210EHA and AQY210EHA are rated for 120 mA and 130 mA respectively due to distinct thermal and component design characteristics. AQW214EHA is rated for 100 mA per channel, reflecting its dual-channel architecture within the 8-SMD package.

Q: Can I use AQY214EHA as a drop-in replacement? A: AQY214EHA provides functional electrical equivalence (SPST-NO, 0–400 V, 120 mA, 1.14 VDC input) but requires board layout revision due to its compact 4-SMD package versus the original 6-SMD footprint. Pinout compatibility must be verified before substitution.

Q: When is AQY414EHA appropriate for use? A: AQY414EHA is suitable only for applications where normally-closed (SPST-NC) relay behavior is required. It is not a substitute for standard normally-open (SPST-NO) circuit implementations.

Q: How do output voltage ranges affect substitution? A: PS7341L-1A operates at 0–400 V output. AQV210EHA and AQW210EHA are limited to 0–350 V maximum output. In applications exceeding 350 V, these models cannot be used. AQV214EHA, AQV214HA, AQW214EHA, and AQY214EHA support the full 0–400 V range and are suitable for high-voltage applications.
