Parameter Comparison

Engineering Selection Recommendations

Both the LC75853NWHS-E and LC75857WS-E are classified as obsolete products. The LC75857WS-E presents a viable substitute based on electrical parameter equivalence and mechanical compatibility.

The LC75857WS-E demonstrates compliance with ROHS3 standards, whereas the LC75853NWHS-E is listed as REACH Unaffected. For applications requiring RoHS compliance, the LC75857WS-E offers regulatory advantage.

The expanded voltage supply range of the LC75857WS-E (2.7V ~ 6V versus 4.5V ~ 6V) provides operational flexibility for designs operating at lower supply voltages while maintaining full compatibility within the original specification range.

Both devices share identical supply current specifications, operating temperature ranges, and package configurations, ensuring direct functional substitution in existing circuit designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LC75857WS-E directly replace the LC75853NWHS-E in existing designs?

A: Yes. Both devices share identical electrical specifications for supply current (300 µA), operating temperature range (-40°C ~ 85°C), serial interface configuration, and 64-LQFP package format. The LC75857WS-E supports the required 126-segment configuration and operates within the original supply voltage specification.

Q: What is the difference in voltage supply range between these parts?

A: The LC75853NWHS-E operates at 4.5V ~ 6V, while the LC75857WS-E operates at 2.7V ~ 6V. The LC75857WS-E extends the lower voltage limit, allowing operation in applications with lower supply voltages while remaining fully compatible with the original 4.5V ~ 6V range.

Q: Are there packaging differences between these parts?

A: Both devices use the 64-LQFP package format with 10x10mm dimensions. The LC75857WS-E is available in both 64-SPQFP and 64-SQFP variants, while the LC75853NWHS-E is specified as 64-SQFP. These package designations are functionally equivalent for PCB placement and soldering operations.

Q: What is the significance of the segment configuration difference?

A: The LC75853NWHS-E is configured for 126 segments. The LC75857WS-E supports both 126-segment and 164-segment configurations. For applications requiring 126-segment operation, the LC75857WS-E operates in the compatible mode without functional limitation.

Q: Are there compliance or regulatory differences?

A: The LC75857WS-E is ROHS3 compliant, providing regulatory advantage for applications subject to RoHS requirements. The LC75853NWHS-E is REACH Unaffected. Both devices carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Why are both parts listed as obsolete?

A: Obsolete status indicates these products are no longer in active production. Substitute identification is necessary for system maintenance and procurement planning when original inventory is depleted.
