STR-A6061HZ Equivalent & Substitute Parts

Part Overview

The STR-A6061HZ is an AC/DC converter integrated circuit manufactured by Sanken Electric USA Inc., classified as a Power Management (PMIC) component. This offline flyback topology converter operates at 100kHz switching frequency and delivers 35W of power output with isolated topology. The device is currently in active product status with 699 units in stock.

Substitute parts are necessary when the primary component becomes unavailable, when design requirements demand alternative power ratings, or when supply chain optimization requires selection from multiple qualified sources within the same parametric family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STR-A6061HZ is determined by strict parametric alignment across the following critical criteria:

Mandatory Matching Parameters:

• Topology: Flyback
• Voltage - Breakdown: 700V
• Voltage - Supply (Vcc/Vdd): 8.5V ~ 32V
• Frequency - Switching: 100kHz
• Duty Cycle: 75%
• Output Isolation: Isolated
• Internal Switch(s): Yes
• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads
• Mounting Type: Through Hole
• Operating Temperature: -40°C ~ 125°C (TA)
• Fault Protection: Current Limiting, Over Load, Over Temperature, Over Voltage
• Control Features: Soft Start
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameters (Allowable Differences):

• Power (Watts): 30W, 35W, 40W
• Voltage - Start Up: 15V, 47V

The substitute parts listed below maintain all mandatory parameters while permitting variation in power output and startup voltage specifications. These variations reflect different design points within the same integrated circuit family, enabling selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full compliance with ROHS3 and REACH regulations. Selection among equivalent parts should be based on the following criteria:

For 35W Power Requirement (Direct Equivalents):

• STR-A6061HZ: 47V startup voltage, 699 units available
• STR6A161HVD: 47V startup voltage, 949 units available
• STR6A161HZ: 15V startup voltage, 850 units available

The STR6A161HZ variant offers reduced startup voltage (15V versus 47V), which may provide operational advantages in low-voltage supply applications. The STR6A161HVD maintains the 47V startup specification matching the primary part.

For 40W Power Requirement:

• STR-A6063HZ: 47V startup voltage, 725 units available

This part delivers increased power capacity while maintaining all other parametric specifications.

For 30W Power Requirement:

• STR-A6069HZ: 47V startup voltage, 3514 units available
• STR6A169HZ: 15V startup voltage, 1050 units available

These parts provide reduced power output specifications. The STR-A6069HZ maintains 47V startup voltage, while STR6A169HZ operates with 15V startup voltage.

All parts share identical package configuration (8-DIP through-hole), thermal operating range (-40°C to 125°C), and protection features, ensuring direct functional substitution within the specified parametric boundaries.

Frequently Asked Questions (FAQ)

Q: Can STR-A6063HZ (40W) be used as a substitute for STR-A6061HZ (35W)?

A: Yes. The STR-A6063HZ is a parametric equivalent with higher power capacity. All electrical specifications, package configuration, and protection features are identical. The increased power rating (40W versus 35W) does not prevent substitution in applications designed for 35W operation.

Q: What is the difference between STR6A161HVD and STR6A161HZ?

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

Q: Are the 30W variants (STR-A6069HZ and STR6A169HZ) suitable replacements for the 35W STR-A6061HZ?

A: These parts are parametric equivalents but with reduced power output. They are suitable substitutes only when the application power requirement does not exceed 30W. The 30W rating represents a design point variation within the same integrated circuit family.

Q: Do all substitute parts use the same 8-DIP package?

A: Yes. All listed substitute parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with 7 leads. Direct board-level substitution is possible without layout modifications.

Q: Are there compliance or regulatory differences between the substitute parts?

A: No. All parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance is uniform across all substitute options.

Q: What determines whether a part can substitute for the STR-A6061HZ?

A: Substitution eligibility requires matching topology (Flyback), voltage breakdown (700V), supply voltage range (8.5V ~ 32V), switching frequency (100kHz), duty cycle (75%), isolation (Isolated), package (8-DIP through-hole), operating temperature range (-40°C ~ 125°C), and protection features. Power output and startup voltage may vary within the specified ranges.

Q: Which substitute part has the highest inventory availability?

A: STR-A6069HZ has the highest inventory with 3514 units in stock, followed by STR-A6063HZ with 725 units. The primary part STR-A6061HZ has 699 units available.

Q: Can I use a lower power-rated part (30W) in a design that requires 35W?

A: No. Using a lower power-rated part in an application exceeding its power specification will result in thermal stress, reduced efficiency, and potential device failure. Power rating selection must match or exceed the application requirement.
