Parameter Comparison

Engineering Selection Recommendations

The MDLS-20464-LV-G is the direct substitute for the obsolete MDLS-20464-SS-LV-G. Both parts maintain identical electrical specifications, mechanical dimensions, and functional characteristics. The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity.

The MDLS-20464-LV-G is RoHS Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment. Character size variations between the main part (4.70mm H x 2.90mm W) and substitute (4.75mm H x 2.95mm W) are within acceptable tolerances for display readability and do not affect functional compatibility or interface requirements.

Selection of the MDLS-20464-LV-G eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs utilizing the MDLS-20464-SS-LV-G.

Frequently Asked Questions (FAQ)

Q: Can the MDLS-20464-LV-G directly replace the MDLS-20464-SS-LV-G in existing applications?

A: Yes. Both parts share identical display format (20 x 4), character matrix (5 x 8 dots), STN reflective technology, 5V supply voltage, parallel interface, operating temperature range (-5°C ~ 50°C), and mechanical outline dimensions (98.00mm x 60.00mm x 7.10mm). Direct substitution is supported without circuit or firmware modifications.

Q: What is the significance of the character size difference between these parts?

A: The character size variation (4.70mm x 2.90mm versus 4.75mm x 2.95mm) represents a minor dimensional tolerance within the same display family. This difference does not affect electrical performance, interface compatibility, or viewing area specifications (76.00mm x 25.20mm). Both configurations maintain the 5 x 8 dot matrix format and are visually equivalent for standard applications.

Q: Why is the MDLS-20464-SS-LV-G classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production of this specific part number variant. The MDLS-20464-LV-G represents the current active production equivalent within the same MDL(S)-20464 series, ensuring continued component availability and supply chain support.

Q: Does the RoHS Compliance status of the substitute part affect compatibility?

A: No. RoHS Compliance of the MDLS-20464-LV-G indicates adherence to environmental and regulatory standards for hazardous substance restrictions. This status does not alter electrical or mechanical compatibility and is beneficial for applications requiring regulatory compliance documentation.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified, while the substitute part is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance. Bulk packaging is standard for production quantities and does not impact circuit integration or operational characteristics.
