Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCM-S02002DTR is determined by strict alignment with the following critical parameters: character count (40), display format (20 x 2), character dot matrix (5 x 8), reflective display mode, 5V supply voltage, parallel interface, and absence of backlight. The substitute part LCM-S02002DSR maintains all critical functional parameters while introducing a variation in display technology from TN to STN (Super-Twisted Nematic) and a physical dimension change in the width dimension (37.00mm versus 28.50mm). Both parts share the same base product number (LCM-S02002), manufacturer, RoHS3 compliance status, and operating temperature range. The substitution is valid where the increased physical width and enhanced contrast characteristics of STN technology are compatible with the application's mechanical and optical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both LCM-S02002DTR and LCM-S02002DSR are active products with full regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection between these parts is determined by mechanical fit and display technology requirements. The LCM-S02002DTR with TN display technology and 28.50mm width is appropriate for applications with space constraints and standard contrast requirements. The LCM-S02002DSR with STN display technology and 37.00mm width provides enhanced contrast characteristics and is suitable for applications where improved visibility is required and the additional 8.50mm width dimension is accommodated within the mechanical design. Both parts maintain identical electrical specifications (5V supply, parallel interface), character capacity (40 characters, 20 x 2 format), and operating temperature range (0°C to 50°C). Component selection should be based on available PCB space and optical performance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can LCM-S02002DSR directly replace LCM-S02002DTR without design modification?

A: Direct replacement requires verification of mechanical fit. The LCM-S02002DSR has a width dimension of 37.00mm compared to 28.50mm for the LCM-S02002DTR. If the PCB layout and enclosure accommodate this 8.50mm width increase, electrical and functional compatibility is maintained. If space is constrained, design modification may be necessary.

Q: What is the functional difference between TN and STN display technologies in these parts?

A: TN (Twisted Nematic) and STN (Super-Twisted Nematic) are both reflective display technologies. STN provides enhanced contrast and wider viewing angles compared to TN. Both operate at identical 5V supply voltage and support the same 20 x 2 character format with 5 x 8 dot matrix. Selection depends on optical performance requirements for the specific application.

Q: Are the electrical interfaces identical between LCM-S02002DTR and LCM-S02002DSR?

A: Yes. Both parts feature parallel interface connectivity, 5V supply voltage, identical character size (5.55mm H x 3.20mm W), and identical dot size (0.60mm W x 0.65mm H). No interface adapter or signal conditioning is required for substitution from an electrical standpoint.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both LCM-S02002DTR and LCM-S02002DSR are ROHS3 Compliant, REACH Unaffected, with MSL Rating 1 (Unlimited). Regulatory compliance is identical between the two parts.

Q: What is the viewing area specification for both parts?

A: Both parts have identical viewing area dimensions of 85.00mm L x 18.60mm W. The difference in overall outline width (28.50mm versus 37.00mm) is due to bezel or mounting frame design, not the active display area.

Q: Are both parts currently in stock?

A: Yes. LCM-S02002DTR has 747 Pcs New Original In Stock. LCM-S02002DSR has 987 Pcs New Original In Stock. Both are classified as active products with full inventory availability.
