Key Parameters

Substitute Part Grouping Explanation

Substitution within the BQ2002 series is determined by parametric equivalence across all critical electrical and mechanical specifications. The following parameters establish substitution validity:

• Battery Chemistry: Multi-Chemistry (all variants)
• Battery Pack Voltage: 2V (all variants)
• Voltage - Supply (Max): 6V (all variants)
• Current - Charging: Constant, Pulsed (all variants)
• Programmable Features: Voltage (all variants)
• Operating Temperature: 0°C ~ 70°C (TA) (all variants)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (all variants)
• Mounting Type: Surface Mount (all variants)
• RoHS Status: ROHS3 Compliant (all variants)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (all variants)

All substitute parts maintain identical electrical performance characteristics and physical form factors, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, BQ2002GSN, BQ2002FSN, and BQ2002CSN are recommended as primary selections due to their Active product status and sustained availability. All three parts maintain full ROHS3 compliance and identical electrical specifications to the BQ2002TSN.

BQ2002TSNG4 is available in limited inventory but carries Discontinued at DiGi Electronics status, making it unsuitable for long-term production commitments. This variant should be reserved for legacy system maintenance or short-term supply bridge applications only.

All substitute parts are REACH Unaffected and classified under ECCN EAR99, maintaining consistent regulatory compliance across the series.

Frequently Asked Questions (FAQ)

Q: Can BQ2002CSN, BQ2002FSN, and BQ2002GSN be used interchangeably with BQ2002TSN?

A: Yes. All three parts are parametric equivalents sharing identical electrical specifications, battery chemistry support, voltage ratings, charging modes, operating temperature range, and 8-SOIC package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between the BQ2002 variant designations (T, C, F, G)?

A: The letter designations represent different manufacturing batches or internal revisions within the BQ2002 series. All variants maintain identical functional performance and electrical characteristics as specified in the parameter comparison table.

Q: Is BQ2002TSNG4 suitable for new production designs?

A: No. BQ2002TSNG4 is Discontinued at DiGi Electronics and should not be selected for new designs. Use BQ2002GSN, BQ2002FSN, or BQ2002CSN instead.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts in this series are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and reliability standards.

Q: What is the maximum supply voltage for all BQ2002 variants?

A: The maximum supply voltage is 6V across all variants. Circuit designs must not exceed this specification.

Q: Can these parts be used in applications requiring different battery chemistries?

A: Yes. All BQ2002 variants support Multi-Chemistry battery charging, enabling use across lithium-ion, nickel-metal hydride, and other compatible battery types within the specified voltage and current parameters.
