Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA6287F-E2 is determined by the following core parameters: brushed DC motor control capability, fully integrated driver architecture with control and power stages, half-bridge output configuration, and bipolar technology. All substitute parts must maintain these functional characteristics.

The substitute parts are grouped into two categories based on interface type and voltage rating:

Category 1: On/Off Interface (Lower Voltage Range)

• TA7267BP(O): Parallel interface control, 6V-18V supply range, 1A output current, through-hole mounting

Category 2: Advanced Control Interface (Higher Voltage Range)

• TB6549FG(O,EL): PWM/Serial interface, 10V-27V supply range, 4.6A output current, surface mount
• TB6549PG(O): PWM/Serial interface, 10V-27V supply range, 4.6A output current, through-hole mounting

All substitute parts share the half-bridge output configuration, brushed DC motor capability, and fully integrated driver architecture required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Lowest Design Impact): The TA7267BP(O) provides the closest functional match with equivalent 1A output current and overlapping voltage range (6V-18V encompasses the BA6287F-E2 operating window of 4.5V-15V). However, this part requires through-hole mounting versus the original surface mount configuration. The parallel interface differs from the on/off control of the BA6287F-E2, requiring control circuit adaptation.

For Higher Current Applications: The TB6549 series (both FG and PG variants) offers 4.6A output current capability with active product status and advanced PWM/Serial control interfaces. These parts operate at higher voltage ranges (10V-27V) and require circuit redesign for control signal implementation. The TB6549FG(O,EL) maintains surface mount compatibility, while the TB6549PG(O) provides through-hole mounting.

Compliance Considerations: All substitute parts maintain RoHS compliance and EAR99 export classification consistent with the original BA6287F-E2. The TA7267BP(O) and TB6549 variants are all classified as Active products, ensuring long-term availability and production support compared to the Not For New Designs status of the BA6287F-E2.

Frequently Asked Questions (FAQ)

Q: Can the TA7267BP(O) be used as a direct pin-for-pin replacement? A: No. While both are half-bridge brushed DC motor drivers with 1A output current, the TA7267BP(O) uses a 7-pin SIP through-hole package versus the 8-pin SOP surface mount package of the BA6287F-E2. Additionally, the control interface differs (parallel versus on/off), requiring circuit modifications.

Q: What is the minimum voltage requirement for substitute parts? A: The TA7267BP(O) operates from 6V minimum, which exceeds the BA6287F-E2 minimum of 4.5V. The TB6549 series requires 10V minimum. Applications requiring operation below 6V must use the original BA6287F-E2 or identify alternative solutions.

Q: Are the TB6549 variants suitable for 1A applications? A: Yes. The TB6549FG(O,EL) and TB6549PG(O) are rated for 4.6A output current, making them suitable for applications requiring 1A or less. However, the higher voltage range (10V-27V) and advanced control interfaces (PWM/Serial) require circuit redesign compared to the BA6287F-E2.

Q: What are the key differences between TB6549FG(O,EL) and TB6549PG(O)? A: Both variants share identical electrical specifications (10V-27V supply, 4.6A output, PWM/Serial interface, -20°C to 85°C operating range). The primary difference is mounting type: TB6549FG(O,EL) is surface mount (20-BSOP with heat tabs), while TB6549PG(O) is through-hole (16-DIP).

Q: Do all substitute parts maintain the same operating temperature range? A: No. The BA6287F-E2 operates to 150°C (TJ), while the TA7267BP(O) operates to 75°C (TA) and TB6549 variants to 85°C (TA). Applications requiring extended temperature operation above 85°C may not be compatible with these substitutes.

Q: Are there inventory considerations for these substitute parts? A: Yes. Current inventory levels are: BA6287F-E2 (125,400 pcs), TA7267BP(O) (1,114 pcs), TB6549FG(O,EL) (853 pcs), and TB6549PG(O) (786 pcs). The original part has significantly higher availability.
