STR-A6061MZ Equivalent & Substitute Parts

Part Overview

The STR-A6061MZ is an AC/DC converter integrated circuit manufactured by Sanken Electric USA Inc., designed for offline flyback topology applications. This isolated power management IC operates at 67 kHz switching frequency with a maximum power output of 31 W and includes integrated protection features for current limiting, overload, over-temperature, and over-voltage conditions. The device is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STR-A6061MZ are identified based on strict electrical and mechanical parameter matching within the AC/DC converter IC category. The substitution logic is based on the following critical parameters that must remain constant:

• Topology: Flyback converter architecture
• Output Isolation: Isolated configuration
• Voltage - Breakdown: 700V rating
• Voltage - Supply Range: 8.5V ~ 32V
• Voltage - Start Up: 47V
• Frequency - Switching: 67 kHz
• Duty Cycle: 75%
• Fault Protection: Current Limiting, Over Load, Over Temperature, Over Voltage
• Control Features: Soft Start
• Operating Temperature Range: -40°C ~ 125°C
• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads
• Mounting Type: Through Hole
• Compliance: RoHS3 Compliant, REACH Unaffected

The STR-A6069MZ meets all these criteria and is classified as a parametric equivalent. The primary difference is the maximum power output rating (26W versus 31W for the main part), which represents a lower power capability and does not prevent substitution in applications requiring 26W or less.

Parameter Comparison

Engineering Selection Recommendations

Both the STR-A6061MZ and STR-A6069MZ are active products manufactured by Sanken Electric USA Inc. with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by application power requirements:

STR-A6061MZ is selected for applications requiring maximum power output of 31W. This part is suitable for higher-power flyback converter designs within the specified electrical parameters.

STR-A6069MZ is selected for applications requiring maximum power output of 26W or less. This part provides equivalent electrical and mechanical compatibility with reduced power capability. The STR-A6069MZ maintains higher inventory availability (3300 pieces versus 911 pieces), which may support supply chain objectives.

Both parts share identical electrical characteristics including breakdown voltage, supply voltage range, switching frequency, duty cycle, protection features, and operating temperature range. Both employ 8-DIP through-hole packaging with identical lead configuration and spacing. Substitution is valid when application power requirements do not exceed 26W.

Frequently Asked Questions (FAQ)

Q: Can the STR-A6069MZ replace the STR-A6061MZ in all applications?

A: The STR-A6069MZ can replace the STR-A6061MZ only in applications where the maximum required power output does not exceed 26W. The STR-A6069MZ has a lower power rating (26W) compared to the STR-A6061MZ (31W). All other electrical and mechanical parameters are identical.
