Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSQC6442C is determined by the following critical parameters:

• Number of Characters: Must be 4-character configuration
• Digit/Alpha Size: Must be 0.56" (14.22mm)
• Display Type: Must be 7-segment LED
• Common Pin Configuration: Must be common cathode
• Color: Must be green
• Voltage - Forward (Vf): Must be 2.1V (typical)
• Current - Test: Must be 20mA
• Millicandela Rating: Must be 2.4mcd

The LTC-5753G-01 from Lite-On Inc. meets all substitution criteria. While minor variations exist in physical dimensions (height: 0.748" vs 0.673"), wavelength (565nm vs 570nm), and power dissipation (75mW vs 70mW), these differences remain within acceptable engineering tolerances for equivalent component selection. The LTC-5753G-01 maintains active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The LTC-5753G-01 is the qualified substitute for the obsolete MSQC6442C. Selection is based on:

• Product Status: The LTC-5753G-01 maintains active product status, ensuring continued availability and manufacturing support, whereas the MSQC6442C is obsolete.
• Compliance: The LTC-5753G-01 is RoHS3 compliant, meeting current regulatory requirements for electronic components.
• Electrical Equivalence: Both components operate at identical forward voltage (2.1V) and test current (20mA) with matching brightness ratings (2.4mcd), ensuring direct functional compatibility in existing circuit designs.
• Physical Compatibility: While the LTC-5753G-01 features a defined 12-DIP package (0.600", 15.24mm) compared to the MSQC6442C's unspecified packaging, the matching digit size (0.56") and similar overall dimensions support PCB layout compatibility with minor adjustments.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5753G-01 directly replace the MSQC6442C in existing designs?

A: Yes. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current, 2.4mcd brightness) and common cathode configuration. The LTC-5753G-01 is electrically and functionally equivalent. PCB layout may require minor adjustments due to the defined 12-DIP package specification of the substitute.

Q: What are the key differences between these two parts?

A: The primary differences are product status (MSQC6442C is obsolete; LTC-5753G-01 is active), wavelength (570nm vs 565nm), maximum power dissipation (70mW vs 75mW), and package definition (unspecified vs 12-DIP). These differences do not affect functional substitution.

Q: Why is wavelength different between the two parts?

A: Both components emit green light within the visible spectrum. The MSQC6442C peaks at 570nm while the LTC-5753G-01 peaks at 565nm. This 5nm difference is imperceptible to the human eye and does not impact visual performance in applications.

Q: Is the LTC-5753G-01 RoHS compliant?

A: Yes. The LTC-5753G-01 is RoHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: What packaging format does the LTC-5753G-01 use?

A: The LTC-5753G-01 is supplied in 12-DIP (0.600", 15.24mm) package format, which is a standard dual inline package configuration suitable for through-hole PCB assembly.
