Key Parameters

Substitute Part Grouping Explanation

The BQ2004ESN qualifies for substitution with the BQ2004SNG4 based on the following critical parameters:

• Package Compatibility: Both parts use 16-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring PCB layout and footprint compatibility
• Electrical Equivalence: Identical maximum supply voltage (5.5V), charging current characteristics (Constant, Pulsed), and programmable voltage features
• Functional Equivalence: Both are multi-chemistry battery charger ICs with identical base product number (BQ2004)
• Operating Range: Matching operating temperature range of -20°C ~ 70°C (TA)
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status

The primary difference is packaging format (Tube vs. Bulk) and manufacturer designation (Texas Instruments vs. Benchmarq), which does not affect electrical or mechanical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the BQ2004ESN and BQ2004SNG4 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Supply Chain Requirements: Both parts maintain active inventory status with comparable stock levels
• Packaging Logistics: BQ2004ESN is supplied in Tube packaging; BQ2004SNG4 is supplied in Bulk packaging. Select based on assembly process requirements and handling procedures
• Regulatory Compliance: Both parts satisfy identical environmental and regulatory requirements for deployment in regulated applications

No additional technical criteria beyond those provided in the parameter set should influence substitution decisions.

Frequently Asked Questions (FAQ)

Q: Can BQ2004SNG4 be used as a direct replacement for BQ2004ESN on the same PCB?

A: Yes. Both parts share identical 16-SOIC package dimensions (0.154", 3.90mm Width) and surface mount footprints. No PCB layout modifications are required.

Q: Are the electrical characteristics identical between BQ2004ESN and BQ2004SNG4?

A: The provided parameters confirm identical electrical specifications: maximum supply voltage (5.5V), charging current modes (Constant, Pulsed), voltage programmability, and operating temperature range (-20°C ~ 70°C).

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging (BQ2004ESN) is used for smaller quantity shipments and manual assembly processes. Bulk packaging (BQ2004SNG4) is used for high-volume automated assembly. The electrical and mechanical properties of the component remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both BQ2004ESN and BQ2004SNG4 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability, packaging requirements, and inventory management needs. Both parts are active production components with equivalent technical specifications.
