BH1772GLC-E2 Equivalent & Substitute Parts

Part Overview

The BH1772GLC-E2 is an ambient light optical sensor manufactured by Rohm Semiconductor, designed for 550nm wavelength detection with I2C output interface. This component operates within a 2.3V to 3.6V supply voltage range and supports proximity detection functionality. The device is packaged in a 10-VFLGA surface mount configuration with ROHS3 compliance and MSL 3 moisture sensitivity rating.

The BH1772GLC-E2 carries a "Not For New Designs" product status, indicating that Rohm Semiconductor has discontinued active development and support for this model. Organizations requiring equivalent functionality for new applications or seeking to replace existing inventory must evaluate qualified substitute components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the BH1772GLC-E2 must satisfy the following electrical and mechanical criteria to ensure functional equivalence:

Critical Matching Parameters:

• Sensor Type: Ambient light detection
• Wavelength: 550nm spectral response
• Output Interface: I2C digital communication protocol
• Proximity Detection: Supported functionality
• Supply Voltage Compatibility: Overlapping or compatible voltage range
• Operating Temperature Range: Minimum -40°C to 85°C coverage
• RoHS Compliance: ROHS3 certification required
• Moisture Sensitivity: MSL 3 or better

The VCNL4040M3OE from Vishay Semiconductor Opto Division qualifies as a substitute based on matching all critical electrical parameters. Both components operate at 550nm wavelength, support I2C output with proximity detection, maintain ROHS3 compliance, and share identical MSL 3 moisture sensitivity ratings. Operating temperature ranges are equivalent across both devices.

Parameter Comparison

Engineering Selection Recommendations

The VCNL4040M3OE represents a qualified electrical substitute for the BH1772GLC-E2 based on matching sensor specifications, output protocol, and regulatory compliance. The substitute component maintains active product status with ongoing manufacturer support, addressing the obsolescence concern associated with the BH1772GLC-E2.

The primary design consideration involves package form factor transition from 10-VFLGA to 8-SMD Module configuration. This packaging difference necessitates PCB layout modification and footprint redesign. The voltage supply range for the VCNL4040M3OE establishes a minimum threshold of 2.5V, compared to the BH1772GLC-E2 minimum of 2.3V. Applications operating below 2.5V require verification of power supply specifications to ensure compatibility.

Both components maintain identical ROHS3 compliance and MSL 3 moisture sensitivity ratings, supporting equivalent supply chain and manufacturing process requirements.

Frequently Asked Questions (FAQ)

Q: Can the VCNL4040M3OE directly replace the BH1772GLC-E2 without PCB modifications?

A: No. The components use different package types (10-VFLGA versus 8-SMD Module), requiring PCB footprint redesign and layout changes. Pin assignments and physical dimensions differ between the two packages.

Q: Are the I2C communication protocols identical between these components?

A: Both components implement I2C output interface for digital communication. Register maps and command structures may differ between manufacturers. Firmware or software driver updates may be necessary to accommodate protocol variations specific to the Vishay device.

Q: What is the voltage supply overlap between these components?

A: The BH1772GLC-E2 operates from 2.3V to 3.6V, while the VCNL4040M3OE operates from 2.5V to 3.6V. The compatible overlap range is 2.5V to 3.6V. Applications requiring operation below 2.5V cannot use the VCNL4040M3OE as a substitute.

Q: Do both components support proximity detection?

A: Yes. Both the BH1772GLC-E2 and VCNL4040M3OE include proximity detection functionality at 550nm wavelength.

Q: Are there regulatory or compliance differences between these components?

A: Both components maintain ROHS3 compliance, MSL 3 moisture sensitivity ratings, and identical operating temperature ranges. No regulatory barriers exist for substitution from a compliance perspective.

Q: What is the significance of the BH1772GLC-E2 "Not For New Designs" status?

A: This designation indicates that Rohm Semiconductor has discontinued active development and support for this component. New product designs should incorporate the VCNL4040M3OE or equivalent active-status alternatives to ensure long-term availability and manufacturer support.
