STR-A6063HD Equivalent & Substitute Parts

Part Overview

The STR-A6063HD is an offline switch flyback converter IC manufactured by Sanken Electric USA Inc., designed for isolated power management applications. This active product operates at 100kHz switching frequency with 40W power handling capability and integrated fault protection including current limiting, overload, over-temperature, and over-voltage protection. The device is housed in an 8-DIP through-hole package and is RoHS compliant with unlimited moisture sensitivity rating.

Alternative models become necessary when addressing specific application requirements such as power budget constraints, inventory availability, or design optimization for lower power applications while maintaining electrical and mechanical compatibility.

Allowable Variation:

• Power (Watts): STR-A6062HD rated at 38W versus STR-A6063HD at 40W represents a 2W reduction within acceptable design margins for applications not requiring maximum power capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the STR-A6063HD and STR-A6062HD maintain active product status with identical RoHS compliance and unlimited moisture sensitivity ratings, ensuring equivalent regulatory and environmental qualification across applications.

Selection between these parts depends on power budget requirements. The STR-A6063HD supports 40W applications, while the STR-A6062HD is suitable for designs requiring up to 38W. Both devices share identical electrical characteristics including 700V breakdown voltage, 8.1V–32V supply range, 100kHz switching frequency, and comprehensive fault protection.

Pin-to-pin compatibility is maintained through identical 8-DIP through-hole packaging, enabling direct substitution without PCB redesign when power specifications align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can STR-A6062HD replace STR-A6063HD in existing designs?

A: Yes, provided the application power requirement does not exceed 38W. The 2W power rating difference represents the only electrical variance between these parts. All other parameters including voltage ratings, switching frequency, topology, package, and fault protection are identical.

Q: Are there pin compatibility concerns between these parts?

A: No. Both devices use identical 8-DIP (0.300", 7.62mm) through-hole packaging with 7 leads. Direct PCB substitution is possible without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both STR-A6063HD and STR-A6062HD are RoHS compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory qualification.

Q: What determines substitution eligibility for these parts?

A: Substitution is determined by matching topology (Flyback), output isolation (Isolated), voltage specifications (700V breakdown, 8.1V–32V supply), switching frequency (100kHz), duty cycle (83%), package type (8-DIP through-hole), and operating temperature range (-20°C to 125°C). Power rating variance of 2W is allowable when application requirements permit.

Q: Are there inventory or packaging differences?

A: The STR-A6063HD is available in 666 pieces with standard packaging, while STR-A6062HD is available in 897 pieces with bulk packaging. Both are new original stock from Sanken Electric USA Inc.
