Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QBSS560R is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Display Type: 7-Segment (exact match required)
• Number of Characters: 1 (exact match required)
• Digit/Alpha Size: 0.56 inches / 14.22mm (exact match required)
• Common Pin Configuration: Common Anode (exact match required)
• Color: Red (exact match required)
• Package / Case: 10-SMD, No Lead (exact match required)
• Packaging Type: Tape & Reel (TR) (exact match required)

Allowable Parameter Variation Ranges:

• Voltage - Forward (Vf): 1.95V to 2.0V (±2.5% tolerance acceptable for common anode red LED displays)
• Current - Test: 20mA (standard test current for this category)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)

The substitute part LDS-SMHTA5604RISIT from Lumex Opto/Components Inc. meets all critical matching parameters and operates within the allowable voltage variation range, qualifying it as a direct substitute for the QBSS560R.

Engineering Selection Recommendations

Primary Part: QBSS560R

The QBSS560R remains the primary selection when available. This part is Active in product status with established inventory (792 units in stock) and meets all regulatory requirements including ROHS3 compliance and REACH unaffected status. The part carries ECCN classification EAR99 and HTSUS code 8541.41.0000.

Substitute Part: LDS-SMHTA5604RISIT

The LDS-SMHTA5604RISIT from Lumex Opto/Components Inc. is qualified as a direct substitute. This part maintains Active product status with higher inventory availability (1,803 units in stock). It meets identical regulatory compliance standards (ROHS3 Compliant, REACH Unaffected, EAR99, HTSUS 8541.41.0000).

Selection Basis:

Both parts are Active products with full regulatory compliance. The substitute part operates at a forward voltage of 1.95V compared to the primary part's 2.0V, representing a 2.5% reduction within acceptable tolerance for common anode red LED display modules. Both parts are packaged identically as 10-SMD, No Lead components in Tape & Reel format, ensuring mechanical and electrical compatibility in surface-mount applications.

The substitute part exhibits lower power dissipation (60mW vs. 70mW) and lower millicandela rating (6mcd vs. 25mcd), which may be relevant for applications with specific brightness requirements. Selection between these parts should be based on application-specific brightness and power budget constraints.

Frequently Asked Questions (FAQ)

Q: Can the LDS-SMHTA5604RISIT replace the QBSS560R in existing designs?

A: Yes. Both parts are 0.56-inch single-character red 7-segment displays with common anode configuration in 10-SMD, No Lead packages. The forward voltage difference (1.95V vs. 2.0V) is within acceptable tolerance for this display category. Mechanical dimensions are compatible for PCB mounting.

Q: What is the difference in brightness between these two parts?

A: The QBSS560R has a millicandela rating of 25mcd at 625nm peak wavelength. The LDS-SMHTA5604RISIT has a millicandela rating of 6mcd at 640nm peak wavelength. The QBSS560R provides higher brightness output. Applications requiring specific brightness levels should account for this difference.

Q: Are there differences in physical dimensions?

A: The QBSS560R measures 0.748" H x 0.492" W x 0.152" D (19.00mm x 12.50mm x 3.85mm). The LDS-SMHTA5604RISIT measures 0.669" H x 0.492" W x 0.154" D (17.00mm x 12.50mm x 3.90mm). The height and depth differ slightly, but both fit the 10-SMD, No Lead package format. Verify PCB layout clearances for your specific application.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and carry HTSUS code 8541.41.0000. Both are suitable for applications requiring these compliance certifications.

Q: What is the moisture sensitivity level for each part?

A: The QBSS560R has MSL 2A (4 Weeks). The LDS-SMHTA5604RISIT has MSL 3 (168 Hours). The QBSS560R has a longer moisture sensitivity window. Consider storage and handling procedures accordingly.

Q: Can I use these parts interchangeably in production?

A: Both parts are qualified substitutes with identical electrical test current (20mA), matching display type, character count, size, and package format. Forward voltage tolerance is within acceptable range for this component category. Verify brightness requirements and physical clearances for your specific PCB design before implementing production changeover.
