MST5460C Equivalent & Substitute Parts

Part Overview

The MST5460C is a 3-character green 7-segment LED display module manufactured by onsemi, packaged in a 30-DIP configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The display operates at 2.1V forward voltage with a 20mA test current, suitable for numeric and alphanumeric display applications requiring standard brightness levels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MST5460C are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable tolerances:

• Number of Characters: Must be 3
• Display Type: Must be 7-Segment
• Common Pin Configuration: Must be Common Cathode
• Color: Must be Green
• Digit/Alpha Size: Must be 0.52" (13.21mm)
• Voltage - Forward (Vf): Must be 2.1V
• Current - Test: Must be 20mA
• Package / Case: Must be 30-DIP (0.600", 15.24mm)

The LTC-5336G from Lite-On Inc. meets all these criteria and qualifies as a direct substitute. Minor variations in physical dimensions (0.689" H x 1.490" W versus 0.697" H x 1.496" W) and wavelength peak (565nm versus 570nm) remain within acceptable engineering tolerances for this component category. The LTC-5336G maintains identical electrical specifications and package footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LTC-5336G serves as the primary substitute for the obsolete MST5460C. Selection should be based on the following factors:

Product Status: The LTC-5336G maintains Active product status, ensuring continued availability and manufacturer support. The MST5460C is classified as Obsolete, necessitating transition to an alternative component.

Compliance and Certifications: The LTC-5336G is RoHS3 Compliant, meeting current environmental and regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, simplifying procurement and export documentation.

Electrical Compatibility: Identical forward voltage (2.1V), test current (20mA), and millicandela rating (2.2mcd) ensure direct functional equivalence in existing circuit designs. The 5mW increase in maximum power dissipation (75mW versus 70mW) remains negligible for thermal design considerations.

Physical Compatibility: Both components utilize the 30-DIP (0.600", 15.24mm) package with matching pin configurations. Dimensional variations are within standard manufacturing tolerances and do not affect PCB layout or mechanical assembly.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5336G be used as a direct replacement for the MST5460C without circuit modifications?

A: Yes. The LTC-5336G maintains identical electrical specifications (2.1V forward voltage, 20mA test current), common cathode configuration, and 30-DIP package footprint. No circuit modifications are required for functional substitution.

Q: What is the significance of the wavelength difference (570nm versus 565nm)?

A: Both wavelengths fall within the green spectrum and are visually indistinguishable in typical display applications. The 5nm difference reflects normal manufacturing variation between suppliers and does not affect perceived color or brightness in practical use.

Q: Are there any compliance differences between the two parts?

A: The LTC-5336G is RoHS3 Compliant, while the MST5460C does not specify RoHS compliance. Both share identical ECCN and HTSUS classifications. For applications requiring RoHS compliance, the LTC-5336G is the appropriate selection.

Q: Does the 5mW increase in power dissipation affect thermal design?

A: No. The increase from 70mW to 75mW is negligible and does not require thermal design modifications. Both components operate within standard thermal management parameters for LED display modules.

Q: Is the LTC-5336G available in sufficient quantity for production use?

A: Current inventory data indicates 1,151 pieces of the LTC-5336G are available as new original stock, supporting both prototype and production-volume requirements.

Q: Are there any mechanical assembly considerations when substituting the LTC-5336G?

A: No. Both components use identical 30-DIP (0.600", 15.24mm) packaging. Physical dimensions vary within standard tolerances (0.689" H x 1.490" W for LTC-5336G versus 0.697" H x 1.496" W for MST5460C) and do not affect PCB mounting or mechanical clearances.
