Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LC75806PT-H is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 100-TQFP (14x14) surface mount package to ensure PCB footprint and assembly process compatibility.

Interface Type: Serial interface requirement must be maintained for signal protocol compatibility with existing system designs.

Display Configuration: The substitute must support segment configurations compatible with or exceeding the 231/304 segment capability of the original part.

Voltage Supply Range: The substitute operating voltage must overlap with or encompass the 4.5V ~ 6V supply range of the LC75806PT-H.

Operating Temperature Range: The substitute must support the -40°C ~ 85°C operating temperature specification.

Regulatory Compliance: RoHS3 compliance and MSL rating equivalence ensure manufacturing and environmental compatibility.

The BU97530KVT-ME2 from Rohm Semiconductor meets these substitution criteria through identical package geometry, serial interface architecture, compatible voltage operation, matching temperature range, and equivalent regulatory certifications.

Enhanced Electrical Performance: The substitute offers lower supply current consumption (130 µA vs. 1.4 mA) and extended voltage supply range (2.7V ~ 6V vs. 4.5V ~ 6V), providing design flexibility for power-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the BU97530KVT-ME2 directly replace the LC75806PT-H on existing PCBs?

A: Yes. Both devices use the 100-TQFP (14x14) surface mount package with identical pin configurations and footprints. No PCB layout modifications are required for physical substitution.

Q: Are there differences in segment configuration between these parts?

A: The BU97530KVT-ME2 supports 445 segments compared to the LC75806PT-H's 231/304 segment capability. The substitute's higher segment count is compatible with applications designed for the original part's segment range.

Q: What is the voltage supply compatibility between these devices?

A: The LC75806PT-H operates at 4.5V ~ 6V, while the BU97530KVT-ME2 operates at 2.7V ~ 6V. The substitute's extended lower voltage range encompasses the original part's operating window, ensuring compatibility with existing power supply designs.

Q: Does the BU97530KVT-ME2 have the same operating temperature range?

A: Yes. Both devices operate across the -40°C ~ 85°C temperature range, ensuring thermal compatibility in equivalent application environments.

Q: What are the supply current differences between these parts?

A: The LC75806PT-H draws 1.4 mA supply current, while the BU97530KVT-ME2 draws 130 µA. The substitute's significantly lower current consumption may provide power efficiency benefits in battery-powered or power-constrained applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the LC75806PT-H and BU97530KVT-ME2 are ROHS3 compliant with identical MSL ratings of 3 (168 Hours), ensuring equivalent environmental and manufacturing compliance.

Q: What is the product availability status for each part?

A: The LC75806PT-H is obsolete and no longer manufactured. The BU97530KVT-ME2 is actively produced by Rohm Semiconductor, providing reliable long-term supply chain availability.
