Substitute Part Grouping Explanation

Substitution eligibility for the LCD-09394 is determined by strict equivalence across the following critical parameters:

Display Format: 16 x 2 character configuration
Number of Characters: 32 total characters
Character Format: 5 x 8 dot matrix
Display Type: STN - Super-Twisted Nematic technology
Display Mode: Transflective operation
Backlight: LED type
Interface: Parallel/Serial dual-mode support
Supply Voltage: 5V operation
Physical Dimensions: 103.00mm x 36.00mm x 7.05mm outline

Engineering Selection Recommendations

The LCD-09395 is a direct functional substitute for the LCD-09394 across all critical electrical and mechanical parameters. The primary distinction is product status: LCD-09394 is obsolete while LCD-09395 is active, making the latter the appropriate choice for new designs and ongoing system support.

Both parts maintain identical compliance certifications relevant to their respective manufacturing dates. LCD-09395 carries ROHS3 compliance, reflecting current regulatory standards, while LCD-09394 carries RoHS compliance consistent with its obsolete status. Both parts share MSL Level 1 (Unlimited) moisture sensitivity classification.

The difference in text color (red versus white) and packaging format (unspecified versus bulk) are cosmetic and logistical variations that do not affect electrical or mechanical interchangeability. Selection between these parts should be based on product availability, supply chain requirements, and visual display preferences for the end application.

Frequently Asked Questions (FAQ)

Q: Can LCD-09395 be used as a direct replacement for LCD-09394 in existing designs?

A: Yes. Both parts share identical display format (16x2), character configuration (32 characters, 5x8 dots), display technology (STN transflective), interface capability (parallel/serial), supply voltage (5V), physical dimensions (103.00mm x 36.00mm x 7.05mm), and operating temperature range (0°C ~ 50°C). No circuit modifications are required.

Q: What is the difference between the text colors of these two parts?

A: LCD-09394 displays red text on a black background, while LCD-09395 displays white text on a black background. This is a visual characteristic only and does not affect electrical performance or interface compatibility.

Q: Are there packaging differences between LCD-09394 and LCD-09395?

A: LCD-09395 is specified as bulk packaging, while LCD-09394 packaging is unspecified in the provided data. Packaging format does not affect functional performance or electrical characteristics.

Q: Why is LCD-09394 listed as obsolete?

A: Product obsolescence is a manufacturer designation indicating that the part is no longer in active production. LCD-09395, as an active product with identical specifications, is the recommended source for new inventory and future designs.

Q: Are both parts RoHS compliant?

A: Yes. LCD-09394 carries RoHS compliance, and LCD-09395 carries ROHS3 compliance. Both meet regulatory requirements for their respective product lifecycles.

Q: What is the moisture sensitivity level for these display modules?

A: Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
