Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MST5160C are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Display Configuration: 3-character, 7-segment, common cathode architecture
• Package Type: 30-DIP (0.600", 15.24mm) form factor
• Character Size: 0.52" (13.21mm) digit/alpha size
• Electrical Compatibility: Forward voltage within acceptable operating range (2.0V–2.1V), test current of 20mA
• Color: Red LED emission
• Physical Envelope: Overall dimensions must accommodate 30-DIP package constraints

The LTC-5336HR from Lite-On Inc. meets all substitution criteria, maintaining identical package geometry, character count, display type, and common cathode configuration. Minor variations in forward voltage (2.0V vs. 2.1V), brightness rating (2.2mcd vs. 0.8mcd), and wavelength (635nm vs. 697nm) remain within acceptable substitution tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The MST5160C is classified as obsolete, necessitating transition to active alternatives. The LTC-5336HR provides direct functional substitution with identical package footprint and electrical interface characteristics. The LTC-5336HR maintains active product status and carries RoHS3 compliance certification, supporting modern supply chain and regulatory requirements. Both components share identical moisture sensitivity level (MSL 1 - Unlimited) and ECCN classification (EAR99), ensuring consistent handling and export compliance.

The LTC-5336HR exhibits higher brightness output (2.2mcd vs. 0.8mcd) and operates at a slightly lower forward voltage (2.0V vs. 2.1V), with marginally increased power dissipation (75mW vs. 40mW). These variations remain within acceptable substitution parameters for 7-segment display applications and do not require circuit redesign for standard implementations.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5336HR directly replace the MST5160C without PCB modifications?

A: Yes. Both components use identical 30-DIP package geometry and common cathode configuration. Pin assignments and electrical interface remain compatible. Physical dimensions are equivalent within manufacturing tolerances (height and width variations <0.01").

Q: What is the significance of the forward voltage difference (2.1V vs. 2.0V)?

A: The 0.1V difference is within standard LED operating tolerances. Existing current-limiting resistor calculations remain valid for both components. No circuit redesign is required.

Q: How do the brightness ratings (0.8mcd vs. 2.2mcd) affect substitution?

A: The LTC-5336HR provides higher brightness output. In applications where the original MST5160C brightness was adequate, the LTC-5336HR will display increased luminosity. Brightness adjustment through current limiting resistors is possible if dimming is required.

Q: Are there compliance or certification differences between these parts?

A: The LTC-5336HR carries RoHS3 compliance certification, while the MST5160C does not specify RoHS status. Both components are REACH Unaffected and share identical ECCN (EAR99) and HTSUS classifications.

Q: What is the wavelength difference (697nm vs. 635nm) and does it matter?

A: The MST5160C emits at 697nm (deep red), while the LTC-5336HR emits at 635nm (standard red). Both are red-spectrum LEDs. Visual color difference may be perceptible in side-by-side comparison but remains within red LED classification. Application-specific color matching requirements should be evaluated.

Q: Is the higher power dissipation of the LTC-5336HR (75mW vs. 40mW) a concern?

A: The increased dissipation reflects higher brightness output. For standard 30-DIP package thermal management, this increase does not present thermal design challenges in typical applications.
