LCD-H401C71TR Equivalent & Substitute Parts Reference

Part Overview

The LCD-H401C71TR is a 4-digit, 4×1 character display module manufactured by Lumex Opto/Components Inc. This reflective 7-segment TN (Twisted Nematic) display operates without backlight and is designed for applications requiring compact visual output in standard lighting conditions. The module features a 5V supply voltage and operates across an extended temperature range of -30°C to 75°C. Product status is Active with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified when original inventory is unavailable, when packaging requirements differ, or when operating temperature specifications can be relaxed within application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LCD-H401C71TR are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is functional equivalence across the following parameters:

Critical Matching Parameters:

• Number of Characters: 4
• Display Format: 4 x 1
• Character Format: 7-Segment
• Display Type: TN - Twisted Nematic
• Display Mode: Reflective
• Character Size: 18.00mm H x 9.00mm W
• Outline Dimensions: 69.85mm x 38.10mm x 2.80mm
• Viewing Area: 62.23mm L x 22.86mm W
• Backlight: Without Backlight
• Voltage - Supply: 5V
• Background Color: Gray
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameters Allowing Substitution:

• Packaging format (Tube vs. Tray)
• Operating Temperature range (when application constraints permit)
• Inventory availability

The LCD-S401C71TR qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and display characteristics. The primary difference is packaging format and operating temperature specification.

Parameter Comparison

Engineering Selection Recommendations

LCD-H401C71TR Selection Criteria:

• Applications requiring extended low-temperature operation down to -30°C
• Applications requiring extended high-temperature operation up to 75°C
• Tube packaging requirement for specific assembly or handling processes
• Original specification compliance mandatory

LCD-S401C71TR Selection Criteria:

• Applications operating within 0°C to 50°C temperature range
• Tray packaging acceptable for assembly processes
• Higher inventory availability (3093 Pcs vs. 920 Pcs)
• Cost optimization when extended temperature range is not required
• Identical electrical and mechanical performance within specified operating range

Both parts maintain Active product status and full regulatory compliance (RoHS3, REACH unaffected). Selection between these parts depends solely on operating temperature requirements and packaging format compatibility with manufacturing processes. No functional performance differences exist within the LCD-S401C71TR operating temperature specification.

Frequently Asked Questions (FAQ)

Q: Can LCD-S401C71TR replace LCD-H401C71TR in all applications?

A: LCD-S401C71TR is functionally equivalent only for applications operating within 0°C to 50°C. Applications requiring operation below 0°C or above 50°C must use LCD-H401C71TR. All other electrical and mechanical specifications are identical.

Q: What is the difference between Tube and Tray packaging?

A: Tube packaging (LCD-H401C71TR) provides individual component protection in cylindrical containers. Tray packaging (LCD-S401C71TR) arranges components in segmented trays. Packaging selection depends on assembly equipment compatibility and handling requirements. Both provide equivalent moisture protection (MSL 1).

Q: Are there any compatibility issues with PCB mounting?

A: No. Both parts share identical outline dimensions (69.85mm x 38.10mm x 2.80mm) and viewing area specifications (62.23mm x 22.86mm). PCB footprints and mounting interfaces are identical.

Q: Do both parts require identical supply voltage?

A: Yes. Both LCD-H401C71TR and LCD-S401C71TR operate at 5V supply voltage. No voltage regulation adjustments are required when substituting between these parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without desiccant packaging or controlled humidity environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LCD-H401C71TR and LCD-S401C71TR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Which part should be selected for new designs?

A: For new designs, LCD-S401C71TR is preferred when operating temperature range 0°C to 50°C is acceptable, due to higher inventory availability and equivalent performance. LCD-H401C71TR should be selected only when extended temperature operation is a design requirement.
