Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HV9910BLG-G are qualified based on the following substitution criteria:

Primary Substitution Parameters:

• Single output LED driver control function
• Analog and/or PWM dimming capability
• Surface mount packaging
• ROHS3 compliance
• Active product status
• Operating temperature range overlap (-40°C minimum)

Topology Flexibility: Substitutes may employ alternative topologies (Step-Up/Boost, SEPIC, Flyback) provided they maintain single-output LED driver control and support the required dimming methods. Topology variation is acceptable when supply voltage range and dimming functionality are preserved.

Voltage Range Consideration: The HV9910BLG-G operates from 8V to 450V. Substitute parts with lower maximum voltage ratings (such as 42V or 100V) are classified as substitutes for applications operating within their specified voltage envelope, not for the full 450V range of the main part.

Parameter Comparison

Engineering Selection Recommendations

AL9910-5SP-13 (Diodes Incorporated): This part maintains the 8-SOIC package footprint compatibility and supports both Analog and PWM dimming. The AC DC Offline Switcher topology with Step-Down and Step-Up capability provides extended application flexibility. Supply voltage range extends to 500V, exceeding the HV9910BLG-G maximum. Operating temperature upper limit is 105°C versus 125°C on the main part. ROHS3 compliant and MSL 1 rating. Suitable for high-voltage offline lighting applications.

LM3409MY/NOPB and LM3409QMYX/NOPB (Texas Instruments): Both variants function as DC DC Controllers with Step-Down topology and support Analog and PWM dimming. Package is 10-HVSSOP, requiring PCB layout modification. Supply voltage range is limited to 6V–42V, restricting use to low-voltage applications. Operating temperature range matches the main part at -40°C to 125°C. LM3409QMYX/NOPB includes AEC-Q100 automotive qualification. MSL rating is 3 (168 Hours). These parts are suitable for automotive and low-voltage LED driver applications only.

LT3756HMSE-2#PBF (Analog Devices Inc.): This DC DC Controller supports multiple topologies (Flyback, SEPIC, Step-Down, Step-Up) in a 16-MSOP-EP package. Supply voltage range is 6V–100V. Frequency range extends to 1MHz. Operating temperature upper limit is 150°C, exceeding the main part. Analog and PWM dimming supported. ROHS3 compliant with MSL 1. Suitable for flexible topology LED driver designs within the 100V maximum supply constraint.

LT3796EFE#TRPBF (Analog Devices Inc.): This DC DC Controller supports SEPIC, Step-Down, and Step-Up topologies in a 28-TSSOP-EP package. Supply voltage range is 6V–100V. Frequency range extends to 1MHz. Operating temperature range is -40°C to 125°C. Analog and PWM dimming supported. ROHS3 compliant with MSL 1. Suitable for multi-topology LED driver applications within the 100V maximum supply constraint.

MAX16819ATT+T (Analog Devices Inc./Maxim Integrated): This DC DC Controller with Step-Down topology is packaged in 6-TDFN (3x3), the smallest footprint among substitutes. Supply voltage range is 4.5V–28V. Frequency is fixed at 2MHz. PWM dimming is supported; Analog dimming is not specified. Operating temperature range is -40°C to 125°C. ROHS3 compliant with MSL 1. Suitable for compact, low-voltage PWM-dimmed LED driver applications only.

Frequently Asked Questions (FAQ)

Q: Can the AL9910-5SP-13 replace the HV9910BLG-G in all applications?

A: The AL9910-5SP-13 is suitable for applications operating within its 15V–500V supply range and requiring Analog or PWM dimming. The 8-SOIC package footprint is compatible. However, the operating temperature upper limit is 105°C versus 125°C on the HV9910BLG-G. Applications requiring the full 8V minimum supply voltage or 125°C upper temperature rating require verification of the AL9910-5SP-13 specifications against design requirements.

Q: Why do the LM3409 variants have a lower maximum supply voltage than the HV9910BLG-G?

A: The LM3409MY/NOPB and LM3409QMYX/NOPB are designed for low-voltage DC DC control applications with a maximum supply voltage of 42V. These parts are not suitable for the high-voltage (450V) applications supported by the HV9910BLG-G. Selection of these parts is restricted to applications operating within the 6V–42V envelope.

Q: What is the significance of the package differences among substitute parts?

A: Package selection affects PCB layout, thermal management, and pin count. The HV9910BLG-G uses 8-SOIC. The AL9910-5SP-13 maintains 8-SOIC compatibility. The LM3409 variants use 10-HVSSOP, requiring layout redesign. The LT3756HMSE-2#PBF uses 16-MSOP-EP, and the LT3796EFE#TRPBF uses 28-TSSOP-EP, both requiring significant layout changes. The MAX16819ATT+T uses 6-TDFN (3x3), the most compact option. Package selection must align with PCB design constraints and thermal requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry REACH Unaffected status, matching the compliance profile of the HV9910BLG-G.

Q: What does MSL rating indicate for component substitution?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. The HV9910BLG-G, AL9910-5SP-13, LT3756HMSE-2#PBF, LT3796EFE#TRPBF, and MAX16819ATT+T all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The LM3409 variants carry MSL 3 (168 Hours), requiring storage and handling within a 168-hour window after moisture exposure. This affects supply chain and manufacturing logistics.

Q: Can PWM-only dimming parts substitute for Analog and PWM dimming requirements?

A: No. The MAX16819ATT+T supports PWM dimming only. Applications requiring Analog dimming capability cannot use this part as a substitute. Verify dimming method requirements before selection.

Q: What is the frequency significance in LED driver IC selection?

A: Switching frequency affects component size, efficiency, and EMI characteristics. The HV9910BLG-G operates at 25kHz or 100kHz. Substitute parts with higher frequencies (LT3756 and LT3796 at 100kHz–1MHz, MAX16819 at 2MHz) may reduce passive component size but require different PCB layout and filtering strategies. Frequency selection must align with application EMI and efficiency requirements.
