Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCD-S401C71TF-1 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Display format: 4 × 1 (4 digits, single row)
• Character format: 7-Segment
• Display type: TN - Twisted Nematic
• Display mode: Transflective
• Backlight configuration: Without Backlight
• Outline dimensions: 69.85mm × 38.10mm × 2.80mm
• Product status: Active

Secondary Compatibility Parameters:

• RoHS compliance status
• Moisture Sensitivity Level (MSL)
• ECCN and HTSUS classifications

The substitute part VI-415-DP-FH-W (Varitronix) meets all primary substitution criteria. Both parts share identical display format, character format, display type, display mode, backlight configuration, and mechanical outline dimensions. Both are ROHS3 compliant with MSL 1 rating and identical ECCN/HTSUS codes, confirming regulatory and compliance alignment.

Parameter Comparison

Engineering Selection Recommendations

LCD-S401C71TF-1 (Lumex Opto/Components Inc.):

• Primary selection for applications with specified 5V supply requirement
• Operating temperature range: 0°C to 50°C
• Active product status with established supply chain (835 pcs in stock)
• ROHS3 compliant, MSL 1 rated

VI-415-DP-FH-W (Varitronix) - Substitute Option:

• Functionally equivalent for 4-digit, 7-segment transflective display applications
• Extended operating temperature range: -10°C to 70°C (broader environmental capability)
• Active product status with higher inventory availability (1,687 pcs in stock)
• ROHS3 compliant, MSL 1 rated
• Character size and viewing area show minor dimensional variations within acceptable tolerance for most mechanical mounting scenarios
• Supply voltage specification not provided in available data; engineering verification recommended for voltage compatibility in specific circuit designs

Both parts are suitable for direct substitution based on display format, character format, display type, display mode, backlight configuration, mechanical outline dimensions, and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: What makes VI-415-DP-FH-W a valid substitute for LCD-S401C71TF-1?

A: Both parts share identical critical specifications: 4-digit, 4 × 1 display format; 7-segment character format; TN twisted nematic display type; transflective display mode; no backlight; 69.85mm × 38.10mm × 2.80mm mechanical outline; ROHS3 compliance; and MSL 1 rating. These parameters define functional and mechanical compatibility for direct replacement.

Q: Are there differences in character size between these parts?

A: Yes. The LCD-S401C71TF-1 has character dimensions of 18.00mm H × 9.00mm W, while the VI-415-DP-FH-W has 17.80mm H × 10.00mm W. These variations are minor and do not affect mechanical mounting or electrical compatibility. Visual appearance may differ slightly due to character aspect ratio differences.

Q: What is the operating temperature difference?

A: The LCD-S401C71TF-1 operates from 0°C to 50°C. The VI-415-DP-FH-W operates from -10°C to 70°C, providing an extended temperature range. For applications within the 0°C to 50°C window, both parts perform equivalently. For applications requiring operation outside this range, the VI-415-DP-FH-W offers broader environmental capability.

Q: Is supply voltage compatibility confirmed for the substitute part?

A: The LCD-S401C71TF-1 specifies 5V supply voltage. The VI-415-DP-FH-W does not provide voltage specification in available technical data. Both parts are transflective TN displays with identical electrical architecture, suggesting voltage compatibility; however, circuit-level verification is necessary for final design confirmation.

Q: What are the packaging differences?

A: The LCD-S401C71TF-1 packaging type is not specified in available data. The VI-415-DP-FH-W is supplied in Box packaging. Packaging differences do not affect electrical or mechanical compatibility for component-level substitution.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for applications where the display format (4 × 1, 7-segment, transflective, no backlight) and mechanical outline (69.85mm × 38.10mm × 2.80mm) are the primary design constraints. Minor character size and viewing area variations do not prevent direct substitution. Voltage compatibility should be confirmed for the VI-415-DP-FH-W in specific circuit implementations.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard 0°C to 50°C operation with confirmed 5V supply, either part is suitable. The VI-415-DP-FH-W is preferred for applications requiring extended temperature range (-10°C to 70°C) or higher inventory availability. The LCD-S401C71TF-1 is preferred when 5V supply voltage must be explicitly confirmed from manufacturer specifications.
