• Voltage - Supply (Vcc/Vdd): 8.5V ~ 32V (identical range)
• Frequency - Switching: 100kHz (uniform across all parts)
• Duty Cycle: 75% (consistent specification)
• Output Isolation: Isolated (maintained across all substitutes)
• Internal Switch(s): Yes (all parts include internal switching)
• Fault Protection: Current Limiting, Over Load, Over Temperature, Over Voltage (identical protection suite)
• Control Features: Soft Start (uniform across all parts)

Mechanical Parameters for Substitution:

• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads (identical across all parts)
• Mounting Type: Through Hole (consistent)
• Supplier Device Package: 8-DIP (uniform)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (all parts meet this requirement)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (consistent)
• REACH Status: REACH Unaffected (uniform)
• Product Status: Active (all substitutes are active)

Variable Parameters (Allowable Differences):

• Voltage - Start Up: 15V or 47V (acceptable variation)
• Power (Watts): 30W, 35W, or 40W (acceptable variation within application tolerance)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—STR-A6063HZ, STR-A6069HZ, STR6A161HVD, and STR6A161HZ—maintain Active product status and full compliance with RoHS3 and REACH requirements, identical to the STR6A169HZ. These parts are suitable for direct substitution in applications where the electrical and mechanical parameters align with circuit design specifications.

Selection Criteria Based on Power Requirements:

For applications requiring 30W output power, the STR6A169HZ and STR-A6069HZ are directly equivalent. The STR-A6069HZ offers higher startup voltage (47V versus 15V), which may be advantageous in certain input supply configurations.

For applications requiring 35W output power, both STR6A161HVD and STR6A161HZ provide this specification. The STR6A161HZ matches the STR6A169HZ startup voltage of 15V, while STR6A161HVD operates at 47V startup voltage.

For applications requiring 40W output power, the STR-A6063HZ is the sole option among the substitute parts, operating at 47V startup voltage.

Selection Criteria Based on Startup Voltage:

Applications designed for 15V startup voltage can utilize STR6A169HZ, STR6A161HZ, or substitute with higher power-rated alternatives if circuit design permits.

Applications designed for 47V startup voltage can utilize STR-A6063HZ, STR-A6069HZ, or STR6A161HVD.

All substitute parts maintain identical package configuration (8-DIP through-hole), operating temperature range (-40°C to 125°C), and protection features, ensuring mechanical and thermal compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can STR-A6063HZ replace STR6A169HZ in a 30W application?

A: STR-A6063HZ is rated for 40W output power, exceeding the 30W requirement of STR6A169HZ. However, the startup voltage differs (47V versus 15V). Substitution is permissible only if the application circuit design accommodates the higher startup voltage specification.

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

A: Both parts share identical electrical specifications except for startup voltage. STR6A161HZ operates at 15V startup, while STR6A161HVD operates at 47V startup. Both deliver 35W output power. Selection depends on the input supply voltage configuration of the application.

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

A: Yes. All parts listed—STR6A169HZ, STR-A6063HZ, STR-A6069HZ, STR6A161HVD, and STR6A161HZ—utilize identical 8-DIP (0.300", 7.62mm) packaging with 7 leads and through-hole mounting. PCB footprints are directly compatible.

Q: Do substitute parts maintain the same protection features?

A: Yes. All substitute parts include identical fault protection: Current Limiting, Over Load, Over Temperature, and Over Voltage protection. Soft Start control feature is uniform across all parts.

Q: What compliance certifications apply to all substitute parts?

A: All parts maintain RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited). All parts are classified as Active product status.

Q: Can STR-A6069HZ be used as a direct replacement for STR6A169HZ?

A: STR-A6069HZ is a direct parametric equivalent for 30W applications. Both parts deliver 30W output power and maintain identical electrical specifications. The primary difference is startup voltage (47V versus 15V). Substitution is valid if the application circuit accommodates the higher startup voltage.

Q: Which substitute part should be selected for maximum power output?

A: STR-A6063HZ delivers the highest power output at 40W among all substitute parts. This part operates at 47V startup voltage and is suitable for applications requiring higher power capacity within the same package and topology constraints.

Q: Are operating temperature ranges identical across all parts?

A: Yes. All parts operate across the identical temperature range of -40°C to 125°C (TA), ensuring thermal compatibility in equivalent application environments.
