Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STR-A6063HZ is determined by the following critical parameters that must remain compatible with the original application:

Mandatory Compatibility Parameters:

• Topology: Flyback (all substitutes must maintain flyback topology)
• Output Isolation: Isolated (all substitutes must provide isolated output)
• Internal Switch(s): Yes (all substitutes must include integrated switching)
• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads (physical and pin compatibility)
• Mounting Type: Through Hole (PCB assembly method)
• Voltage - Supply (Vcc/Vdd): 8.5V ~ 32V (supply voltage range)
• Duty Cycle: 75% (operational duty cycle)
• Fault Protection: Current Limiting, Over Load, Over Temperature, Over Voltage (protection feature set)
• Control Features: Soft Start (control methodology)
• Operating Temperature: -40°C ~ 125°C (TA) (thermal operating range)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (handling requirements)
• REACH Status: REACH Unaffected (regulatory status)

Variable Parameters Allowing Substitution:

• Voltage - Breakdown: 650V or 700V (voltage rating variation)
• Frequency - Switching: 65kHz or 100kHz (switching frequency variation)
• Power (Watts): 30W, 35W, or 40W (power output rating variation)
• Voltage - Start Up: 15V or 47V (startup voltage threshold variation)

All identified substitute parts maintain the mandatory compatibility parameters while offering alternative specifications in the variable parameters category.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status with ROHS3 compliance and REACH unaffected regulatory classification, ensuring equivalent environmental and regulatory standing to the STR-A6063HZ.

STR-A6069HZ provides direct substitution for applications where 30W power output is acceptable. This part maintains identical switching frequency (100kHz), voltage breakdown rating (700V), and startup voltage (47V) specifications. Inventory availability is significantly higher at 3514 units compared to 725 units for the STR-A6063HZ.

STR6A153MV operates at reduced switching frequency (65kHz) with 40W power output matching the original part. The voltage breakdown rating is reduced to 650V. This part is suitable for applications where lower switching frequency is compatible with system design requirements.

STR6A161HVD provides 35W power output at 100kHz switching frequency with 700V breakdown voltage. The startup voltage remains at 47V, maintaining compatibility with original circuit design parameters.

STR6A161HZ offers 35W power output at 100kHz switching frequency with 700V breakdown voltage. This part features reduced startup voltage of 15V compared to the original 47V specification, enabling operation in applications with lower input voltage thresholds.

STR6A169HZ provides 30W power output at 100kHz switching frequency with 700V breakdown voltage and 15V startup voltage. This part combines reduced power output with lower startup voltage requirements.

Selection between substitute parts depends on application-specific power output requirements, switching frequency compatibility, and startup voltage thresholds. All parts maintain identical package configuration, mounting methodology, thermal operating range, and protection feature sets.

Frequently Asked Questions (FAQ)

Q: Can STR-A6069HZ replace STR-A6063HZ in all applications?

A: STR-A6069HZ is suitable for applications where 30W power output meets system requirements. The original STR-A6063HZ is rated for 40W output. Substitution is valid only when the application power demand does not exceed 30W. All other electrical and mechanical parameters remain identical.

Q: What is the primary difference between STR6A161HVD and STR6A161HZ?

A: Both parts operate at 100kHz switching frequency with 35W power output and 700V breakdown voltage. The primary difference is the startup voltage threshold: STR6A161HVD requires 47V startup voltage while STR6A161HZ operates with 15V startup voltage. Selection depends on the input voltage characteristics of the application circuit.

Q: Is STR6A153MV compatible with STR-A6063HZ in terms of package and mounting?

A: Yes. STR6A153MV maintains identical 8-DIP package configuration with 0.300" (7.62mm) spacing and 7-lead through-hole mounting. Physical and electrical pin compatibility is maintained. The primary difference is the reduced switching frequency (65kHz versus 100kHz) and reduced breakdown voltage (650V versus 700V).

Q: Why does STR6A153MV operate at 65kHz instead of 100kHz?

A: STR6A153MV is specified with 65kHz switching frequency as a design variant within the Sanken Electric STR series. This parameter is provided in the component specification and determines substitution eligibility based on application switching frequency requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (STR-A6069HZ, STR6A153MV, STR6A161HVD, STR6A161HZ, STR6A169HZ) maintain ROHS3 compliance and REACH unaffected status, matching the regulatory classification of the original STR-A6063HZ.

Q: What is the significance of the 47V versus 15V startup voltage difference?

A: Startup voltage determines the minimum input voltage level required for the converter to begin operation. STR-A6063HZ, STR-A6069HZ, STR6A153MV, and STR6A161HVD require 47V startup voltage. STR6A161HZ and STR6A169HZ operate with 15V startup voltage. Selection depends on the input voltage characteristics and circuit design requirements.

Q: Can STR6A169HZ replace STR-A6063HZ in high-power applications?

A: No. STR6A169HZ is rated for 30W power output compared to the original 40W specification. Substitution is valid only for applications where power demand does not exceed 30W. Using this part in applications requiring 40W output will result in insufficient power delivery.

Q: Do all substitute parts maintain the same thermal operating range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 125°C (TA), matching the original STR-A6063HZ specification.

Q: What is the Moisture Sensitivity Level (MSL) for all parts?

A: All parts, including the original STR-A6063HZ and all substitute parts, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
