Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BQ2014HSNG4 are identified based on the following critical parameters:

Parametric Equivalence Criteria:

• Function: Battery Monitor
• Battery Chemistry: Multi-Chemistry support
• Mounting Type: Surface Mount
• RoHS and REACH compliance status
• Manufacturer: Texas Instruments

Substitution Categories:

Parametric Equivalent (Direct Package Match): BQ2010SN-D107 maintains identical package geometry (16-SOIC), operating temperature range (0°C ~ 70°C), and all compliance certifications. This part is suitable for direct PCB replacement without layout modifications.

Manufacturer Recommended Substitute (Enhanced Specification): BQ34Z100PW-G1 offers expanded operating temperature range (-40°C ~ 85°C) and additional interface options (HDQ, I2C), packaged in 14-TSSOP. This substitute requires PCB layout redesign but provides enhanced functionality and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct PCB Replacement (No Layout Changes): Select BQ2010SN-D107. This part maintains identical package dimensions, pin count, and operating temperature specifications as the BQ2014HSNG4. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory continuity. The BQ2010SN-D107 is currently active with substantial inventory availability (39,000 pcs), providing supply chain stability.

For Enhanced Performance and Extended Temperature Range: Select BQ34Z100PW-G1. This part expands the operating temperature range to -40°C ~ 85°C and includes HDQ and I2C interface options. The trade-off is a package change from 16-SOIC to 14-TSSOP, requiring PCB layout redesign. This part is actively manufactured by Texas Instruments with high inventory levels (129,031 pcs), ensuring long-term availability. All compliance certifications (ROHS3, REACH unaffected) are maintained.

Compliance Continuity: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original BQ2014HSNG4 specifications. Moisture sensitivity levels remain consistent at MSL 2 (1 Year) across all three parts.

Frequently Asked Questions (FAQ)

Q: Can BQ2010SN-D107 be used as a direct replacement for BQ2014HSNG4? A: Yes. BQ2010SN-D107 is a parametric equivalent with identical package geometry (16-SOIC), pin configuration, and operating temperature range (0°C ~ 70°C). No PCB modifications are required for this substitution.

Q: What is the primary difference between BQ2010SN-D107 and BQ34Z100PW-G1? A: BQ2010SN-D107 maintains the original 16-SOIC package and operating temperature range, while BQ34Z100PW-G1 uses a 14-TSSOP package with an expanded operating temperature range (-40°C ~ 85°C) and additional communication interfaces (HDQ, I2C). BQ34Z100PW-G1 requires PCB layout redesign.

Q: Are both substitute parts compliant with current regulations? A: Yes. Both BQ2010SN-D107 and BQ34Z100PW-G1 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original BQ2014HSNG4.

Q: Which substitute should I select if my application requires extended temperature operation? A: BQ34Z100PW-G1 supports -40°C ~ 85°C operating temperature, compared to 0°C ~ 70°C for both BQ2014HSNG4 and BQ2010SN-D107. This part is suitable for industrial and automotive applications requiring wider temperature ranges.

Q: What is the package footprint difference between these parts? A: BQ2014HSNG4 and BQ2010SN-D107 both use 16-SOIC (0.154", 3.90mm width). BQ34Z100PW-G1 uses 14-TSSOP (0.173", 4.40mm width), requiring PCB redesign for pin-to-pin compatibility.

Q: Are there inventory concerns with these substitute parts? A: No. BQ2010SN-D107 has 39,000 pcs in stock, and BQ34Z100PW-G1 has 129,031 pcs in stock, providing stable supply for production requirements.
