Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PR33MF51YSLH is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Package / Case: Must be 8-DIP (0.300", 7.62mm), 7 Leads for PCB compatibility and mounting
• Mounting Type: Must be Through Hole to ensure mechanical fit
• Termination Style: Must be PC Pin for solder connection compatibility
• Output Type: Must be AC for load switching capability
• Load Current: Must support minimum 300mA at rated voltage
• Input Voltage: Must be compatible with 1.2VDC control signal (tolerance range 1.2VDC ±10%)
• Load Voltage: Must support 0V ~ 240V minimum range

The AQH0223 from Panasonic Electric Works meets all substitution criteria while offering enhanced load voltage capability (0V ~ 600V), making it a direct functional equivalent with extended operating range.

Parameter Comparison

Engineering Selection Recommendations

Both the PR33MF51YSLH and AQH0223 are active production components with current RoHS compliance certifications. The AQH0223 provides identical electrical performance for the specified 240V load range while supporting extended voltage operation to 600V. Input voltage specifications are equivalent within standard component tolerances (1.2VDC vs. 1.21VDC). Both components maintain identical mechanical form factors, package configurations, and termination styles, ensuring direct PCB compatibility without layout modifications.

Selection between these parts should be based on supply chain availability, lead time requirements, and cost considerations, as both meet the functional requirements for SPST-NO AC relay switching at 300mA.

Frequently Asked Questions (FAQ)

Q: Can the AQH0223 be used as a direct replacement for the PR33MF51YSLH?

A: Yes. Both components share identical circuit configuration (SPST-NO), package type (8-DIP, 7 Leads), mounting method (Through Hole), and load current rating (300mA). The AQH0223 supports the full 240V load range required by the PR33MF51YSLH application.

Q: What is the difference in load voltage capability between these parts?

A: The PR33MF51YSLH is rated for 0V ~ 240V loads, while the AQH0223 supports 0V ~ 600V. For applications requiring only 240V operation, both parts are functionally equivalent. The AQH0223 provides additional voltage margin for higher-voltage applications.

Q: Are the input voltage specifications compatible?

A: Yes. The PR33MF51YSLH requires 1.2VDC input, and the AQH0223 requires 1.21VDC input. This 0.01VDC difference is within standard component tolerance ranges and does not affect circuit compatibility.

Q: Do these parts require any PCB layout modifications for substitution?

A: No. Both components use identical 8-DIP (0.300", 7.62mm) packaging with 7 PC Pin leads. Direct PCB substitution is possible without layout changes.

Q: What compliance certifications apply to both parts?

A: The PR33MF51YSLH is RoHS Compliant. The AQH0223 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions for industrial applications.
