Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STR6A161HZ is determined by strict adherence to the following core parameters:

Fixed Parameters (Must Match Exactly):

• Topology: Flyback
• Voltage - Breakdown: 700V
• Voltage - Supply (Vcc/Vdd): 8.5V ~ 32V
• Frequency - Switching: 100kHz
• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads
• Mounting Type: Through Hole
• Output Isolation: Isolated
• Internal Switch(s): Yes
• Operating Temperature: -40°C ~ 125°C (TA)
• Manufacturer: Sanken Electric USA Inc.
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters (Allowed to Differ):

• Voltage - Start Up: 15V or 47V
• Power (Watts): 30W, 35W, or 40W
• Duty Cycle: 75% (consistent across all parts)

All substitute parts maintain identical electrical isolation, switching characteristics, thermal operating range, and regulatory compliance. Substitution is valid when the application circuit design accommodates the specified voltage startup and power output variations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with full RoHS3 compliance and REACH unaffected regulatory standing. Selection between STR6A161HZ and its equivalents is determined by application-specific requirements for voltage startup behavior and power output capacity.

STR6A161HZ and STR6A169HZ share identical 15V startup voltage specification, differing only in power output (35W versus 30W respectively). These parts are interchangeable in applications where 15V startup is required and power demand does not exceed 30W.

STR-A6063HZ and STR-A6069HZ operate with 47V startup voltage specification. STR-A6063HZ provides 40W output capacity, while STR-A6069HZ delivers 30W. These parts are interchangeable in applications where 47V startup is required and power demand does not exceed 30W.

STR6A161HVD combines 47V startup voltage with 35W power output, providing intermediate specifications between the 15V and 47V startup families.

All parts maintain identical 700V breakdown voltage, 100kHz switching frequency, 8-DIP through-hole package configuration, isolated output topology, and -40°C to 125°C operating temperature range. Component selection must align with the specific voltage startup requirement and maximum power output specification of the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can STR6A161HZ be replaced with STR-A6063HZ?

A: Substitution is valid only if the application circuit design accommodates the 47V startup voltage requirement of STR-A6063HZ. The STR6A161HZ operates with 15V startup, while STR-A6063HZ requires 47V. Both parts share identical 700V breakdown voltage, 100kHz switching frequency, 8-DIP package, and isolated output topology. Power output differs (35W versus 40W), which must be evaluated against application requirements.

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

A: Both parts deliver 35W power output and share identical 700V breakdown voltage, 100kHz switching frequency, 8-DIP package configuration, and isolated output topology. The key difference is startup voltage: STR6A161HZ operates at 15V startup, while STR6A161HVD operates at 47V startup. Selection depends on the specific voltage startup requirement of the application circuit.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts utilize identical 8-DIP (0.300", 7.62mm) through-hole package configuration with 7 leads. PCB footprint and mounting hole spacing are identical across all listed parts. No PCB layout modification is required for substitution.

Q: What determines whether a part can substitute for STR6A161HZ?

A: Substitution eligibility requires matching topology (Flyback), voltage breakdown (700V), supply voltage range (8.5V ~ 32V), switching frequency (100kHz), package type (8-DIP through-hole), output isolation (Isolated), internal switching capability, operating temperature range (-40°C ~ 125°C), and regulatory compliance (RoHS3, REACH unaffected). Voltage startup and power output specifications may vary within the defined substitute family.

Q: Can STR-A6069HZ replace STR-A6063HZ?

A: Both parts operate with 47V startup voltage and share identical 700V breakdown voltage, 100kHz switching frequency, 8-DIP package, and isolated output topology. The primary difference is power output: STR-A6063HZ delivers 40W while STR-A6069HZ delivers 30W. Substitution is valid only if application power requirements do not exceed 30W.

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

A: Startup voltage specifies the minimum supply voltage at which the converter begins operation. STR6A161HZ and STR6A169HZ require 15V startup, while STR-A6063HZ, STR-A6069HZ, and STR6A161HVD require 47V startup. Application circuit design must provide adequate supply voltage to meet the startup requirement of the selected part. This parameter is not interchangeable between parts.

Q: Are all parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tube packaging with 8-DIP (0.300", 7.62mm) through-hole configuration. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
