Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCD-09393 is determined by strict equivalence across the following critical parameters:

Display Specifications: 16x2 character format with 5x8 dot matrix, 32-character total capacity, STN display technology, and transflective operating mode.

Physical Dimensions: Outline dimensions of 103.00mm x 36.00mm x 7.05mm to ensure mechanical compatibility with existing mounting and housing designs.

Electrical Interface: 5V supply voltage, parallel/serial interface capability, and LED backlight configuration.

Operating Conditions: Temperature range of 0°C to 50°C and moisture sensitivity level MSL 1 (unlimited).

Compliance Standards: RoHS compliance status and ECCN/HTSUS classifications for regulatory alignment.

The LCD-09395 qualifies as a direct substitute based on matching all critical parameters. Differences in text/background color (white on black versus black on green) and product status (active versus obsolete) do not affect functional substitutability for applications where display contrast and visibility requirements are met by either color configuration.

Parameter Comparison

Engineering Selection Recommendations

The LCD-09395 is the qualified substitute for the obsolete LCD-09393. Both parts maintain identical electrical, mechanical, and interface specifications, ensuring direct compatibility in existing circuit designs and mechanical assemblies.

Product Status Consideration: The LCD-09393 is obsolete, while the LCD-09395 maintains active product status with current inventory availability (941 pcs in stock). Selection of the LCD-09395 ensures long-term supply chain continuity and access to current manufacturing batches.

Compliance Alignment: Both parts meet RoHS requirements. The LCD-09395 carries ROHS3 compliance, representing the current regulatory standard. The LCD-09395 is the preferred choice for new designs and systems requiring current compliance documentation.

Color Configuration Difference: The primary distinction between these parts is the display color scheme. The LCD-09393 features black text on green background, while the LCD-09395 provides white text on black background. Selection between these configurations depends on application-specific visibility and contrast requirements. Both configurations maintain identical luminance and readability characteristics within the specified operating temperature range.

Packaging: The LCD-09395 is supplied in bulk packaging, suitable for production environments and volume applications.

Frequently Asked Questions (FAQ)

Q: Can the LCD-09395 be used as a direct replacement for the LCD-09393 in existing designs?

A: Yes. The LCD-09395 is electrically and mechanically equivalent to the LCD-09393. All critical parameters including display format, dimensions, voltage supply, interface type, and operating temperature range are identical. No circuit modifications or mechanical redesign is required.

Q: What is the primary difference between the LCD-09393 and LCD-09395?

A: The display color configuration differs. The LCD-09393 displays black text on a green background, while the LCD-09395 displays white text on a black background. Both configurations use identical STN transflective technology and LED backlight. The choice between them depends on application visibility requirements and user preference for contrast.

Q: Why is the LCD-09393 listed as obsolete?

A: The LCD-09393 has been discontinued by the manufacturer. The LCD-09395 is the active equivalent product and is recommended for all new designs and replacement applications.

Q: Are there any compatibility concerns when substituting the LCD-09395 for the LCD-09393?

A: No compatibility concerns exist. Both parts share identical pinout, voltage requirements, interface protocols, and mechanical mounting specifications. Substitution requires no firmware changes, circuit modifications, or mechanical adjustments.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. The LCD-09395 carries ROHS3 certification, making it the preferred choice for systems requiring current compliance documentation.

Q: Can both parts operate across the same temperature range?

A: Yes. Both the LCD-09393 and LCD-09395 operate across the identical temperature range of 0°C to 50°C. No thermal performance differences exist between these parts.

Q: Is packaging a consideration when selecting between these parts?

A: The LCD-09395 is supplied in bulk packaging, suitable for production environments. If specific packaging requirements exist for your application, verify packaging compatibility before procurement. Both parts are functionally identical regardless of packaging configuration.
