Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory alignment with the primary STR-A6069HZ device. Selection between substitute options is determined by application-specific power requirements and startup voltage specifications.

STR-A6063HZ provides 40 W output power with 47 V startup voltage, suitable for applications requiring higher power delivery while maintaining identical electrical characteristics and package form factor.

STR6A161HVD delivers 35 W output power with 47 V startup voltage, offering intermediate power capability between the 30 W and 40 W options within the same startup voltage class.

STR6A161HZ provides 35 W output power with reduced 15 V startup voltage, enabling operation in lower supply voltage environments while preserving all protection and control features.

STR6A169HZ matches the 30 W power rating of the primary part with reduced 15 V startup voltage, providing direct functional equivalence with enhanced low-voltage startup capability.

All substitute parts share identical 8-DIP through-hole packaging, enabling direct PCB layout compatibility without redesign. Compliance certifications, fault protection mechanisms, and thermal operating ranges remain constant across all options.

Frequently Asked Questions (FAQ)

Q: Can STR-A6063HZ replace STR-A6069HZ in existing designs?

A: STR-A6063HZ is electrically compatible with identical topology, isolation, switching frequency, and protection features. The primary difference is increased power rating (40 W versus 30 W). Substitution is valid when the application circuit can accommodate the higher power capability. Both parts share identical 8-DIP package specifications and through-hole mounting requirements.

Q: What is the difference between STR6A161HVD and STR6A161HZ?

A: Both parts deliver 35 W output power with identical topology and package specifications. The primary distinction is startup voltage: STR6A161HVD requires 47 V startup while STR6A161HZ operates with 15 V startup. Selection depends on the minimum supply voltage available in the target application circuit.

Q: Are STR6A161HZ and STR6A169HZ interchangeable?

A: Both parts feature 15 V startup voltage and 8-DIP through-hole packaging. The difference is power rating: STR6A161HZ provides 35 W while STR6A169HZ provides 30 W. Substitution of STR6A161HZ for STR6A169HZ is valid when higher power capability is acceptable. Reverse substitution (STR6A169HZ for STR6A161HZ) requires circuit verification to confirm 30 W power delivery meets application requirements.

Q: Do all substitute parts maintain the same fault protection?

A: All listed substitute parts include identical fault protection mechanisms: current limiting, overload protection, over-temperature protection, and over-voltage protection. Soft start control features are present across all options.

Q: Is PCB layout modification required when substituting parts?

A: No PCB layout modification is required. All substitute parts use identical 8-DIP (0.300", 7.62mm) package specifications with 7 leads and through-hole mounting. Direct pin-for-pin substitution is supported without redesign.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the identical temperature range of -40°C to 125°C (TA), ensuring thermal compatibility in applications requiring extended temperature operation.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the regulatory designation of the primary STR-A6069HZ device.

Q: Which substitute part should be selected for lowest startup voltage?

A: Both STR6A161HZ and STR6A169HZ feature 15 V startup voltage, the lowest among all options. STR6A161HZ provides 35 W power while STR6A169HZ provides 30 W. Selection depends on required power delivery for the specific application.
