HF500GS-7-Z Equivalent & Substitute Parts

Part Overview

The HF500GS-7-Z is an offline switch flyback converter IC manufactured by Monolithic Power Systems Inc., designed for isolated power management applications. This active product operates at 65kHz switching frequency with 1.5W power output capability and integrated fault protection including over-load, over-temperature, over-voltage, and short-circuit detection. The device is housed in an 8-SOIC package with 7 leads and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit designs, maintaining functional compatibility while potentially offering different inventory availability or packaging options.

Key Parameters

Substitute Part Grouping Explanation

The HF500GS-15-Z qualifies as a parametric equivalent based on the following matching criteria:

• Identical manufacturer: Monolithic Power Systems Inc.
• Identical base product number: HF500
• Identical topology: Flyback converter
• Identical output isolation: Isolated
• Identical voltage breakdown rating: 700V
• Identical supply voltage range: 12.5V ~ 24V
• Identical power rating: 1.5 W
• Identical fault protection features: Over Load, Over Temperature, Over Voltage, Short Circuit
• Identical control features: Soft Start
• Identical package type: 8-SOIC with 7 leads
• Identical operating temperature range: -40°C ~ 125°C (TJ)
• Identical compliance: ROHS3, REACH Unaffected

The primary difference is the switching frequency: HF500GS-7-Z operates at 65kHz while HF500GS-15-Z operates at 25kHz. Both devices maintain identical electrical and mechanical specifications, allowing substitution based on application frequency requirements.

Parameter Comparison

Engineering Selection Recommendations

Both HF500GS-7-Z and HF500GS-15-Z are active products with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts depends on application-specific switching frequency requirements. The HF500GS-7-Z operates at 65kHz, while the HF500GS-15-Z operates at 25kHz. Both devices maintain identical electrical ratings, fault protection capabilities, and thermal specifications. Component selection should be based on circuit design frequency specifications and transformer design parameters that correspond to the switching frequency of the selected device.

Frequently Asked Questions (FAQ)

Q: Can HF500GS-15-Z replace HF500GS-7-Z in existing designs?

A: Direct replacement is possible only if the application circuit design accommodates the 25kHz switching frequency of the HF500GS-15-Z. The HF500GS-7-Z operates at 65kHz. Transformer and filter component designs are frequency-dependent and must be verified for compatibility with the substitute part's switching frequency.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" width (3.90mm) and 7 leads. PCB footprints and mounting procedures are identical.

Q: Do both parts have the same fault protection capabilities?

A: Yes. Both HF500GS-7-Z and HF500GS-15-Z include identical fault protection: over-load, over-temperature, over-voltage, and short-circuit protection, with soft-start control features.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape for automated assembly equipment. Cut Tape (CT) and Digi-Reel® packaging provides smaller quantities cut from the reel. Both contain identical components; packaging format differs only in supply method and quantity per unit.

Q: Are both parts RoHS compliant?

A: Yes. Both HF500GS-7-Z and HF500GS-15-Z are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
