Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LK202-25-USB-FB-E is determined by strict alignment with the following core parameters:

• Display Resolution: 40 characters, 20 x 2 format, 5 x 8 dot matrix
• Interface Protocol: USB connectivity
• Electrical Compatibility: 4.75V ~ 5.25V supply voltage
• Operating Environment: -20°C ~ 70°C temperature range
• Physical Envelope: Dimensions compatible with 116.00mm x 37.00mm footprint
• Base Product Series: LK202 family designation

All four substitute parts (LK202-25-USB-FA-E, LK202-25-USB-FG-E, LK202-25-USB-IY-E, LK202-25-USB-R-E) maintain identical character count, display format, dot matrix structure, USB interface, voltage specification, and operating temperature range. Variations exist only in display technology type, backlight implementation, and color characteristics—parameters that do not affect functional substitution within the LK202 series architecture.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Candidates: LK202-25-USB-FA-E, LK202-25-USB-IY-E, and LK202-25-USB-R-E are direct functional equivalents to the LK202-25-USB-FB-E. All three maintain active product status and carry RoHS compliance certification, providing regulatory advantage over the obsolete original part. These three variants employ LCD monochrome or color display technology with identical electrical and dimensional specifications.

Secondary Substitution Candidate: LK202-25-USB-FG-E employs FFSTN (Double Film Super-Twisted Nematic) display technology with LED green backlight and transmissive display mode. While maintaining identical character count, format, interface, voltage, and temperature specifications, this variant exhibits different physical height (27.70mm versus 29.00mm) and expanded viewing area (83.00mm L x 18.60mm W versus 74.60mm L x 11.50mm W). This part is active and RoHS compliant.

Compliance Advantage: All substitute parts carry RoHS Compliant certification, whereas the original LK202-25-USB-FB-E does not specify RoHS status. For applications subject to environmental or regulatory compliance requirements, active substitute parts provide documented compliance assurance.

Frequently Asked Questions (FAQ)

Q: Can LK202-25-USB-FA-E, LK202-25-USB-IY-E, or LK202-25-USB-R-E be used as direct replacements for the LK202-25-USB-FB-E?

A: Yes. These three parts maintain identical character count (40), display format (20 x 2), character matrix (5 x 8 dots), USB interface, voltage specification (4.75V ~ 5.25V), operating temperature range (-20°C ~ 70°C), and physical footprint (116.00mm x 37.00mm). Differences in text color (amber, yellow, red versus blue) do not affect functional compatibility or electrical interface requirements.

Q: What is the difference between the LK202-25-USB-FG-E and other substitute options?

A: The LK202-25-USB-FG-E uses FFSTN display technology with LED green backlight and transmissive display mode, compared to the monochrome LCD technology of other variants. The FG-E variant has a reduced height (27.70mm versus 29.00mm) and larger viewing area (83.00mm L x 18.60mm W). All other electrical and interface parameters remain identical. Physical dimension differences may affect mechanical fit in existing enclosures.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts (LK202-25-USB-FA-E, LK202-25-USB-FG-E, LK202-25-USB-IY-E, LK202-25-USB-R-E) carry RoHS Compliant certification. The original LK202-25-USB-FB-E does not specify RoHS status.

Q: What is the product status difference between the main part and substitutes?

A: The LK202-25-USB-FB-E is classified as obsolete. All four substitute parts maintain active product status, ensuring ongoing availability and manufacturer support.

Q: Do all parts use the same USB interface protocol?

A: Yes. All parts in this comparison employ USB interface connectivity with identical voltage supply requirements (4.75V ~ 5.25V) and operating temperature specifications (-20°C ~ 70°C).

Q: Can the LK202-25-USB-FG-E be used in applications with strict dimensional constraints?

A: The LK202-25-USB-FG-E has different physical dimensions than the original part. Height is reduced to 27.70mm (versus 29.00mm), and viewing area is expanded to 83.00mm L x 18.60mm W (versus 74.60mm L x 11.50mm W). Mechanical fit verification is required before substitution in space-constrained applications.
