Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACSC56-41SRWA-F01 is based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Display type: 7-Segment configuration
• Number of characters: Single character (1)
• Common pin configuration: Common Cathode
• Color: Red
• Digit size: 0.56" (14.22mm)
• Package type: 10-SMD, No Lead
• Packaging format: Tape & Reel (TR)
• Physical dimensions: 0.669" H x 0.488" W x 0.148" D (17.00mm x 12.40mm x 3.75mm)

Allowable Parameter Variations:

• Forward voltage (Vf): Typical values within the red LED spectrum (1.85V to 1.95V)
• Millicandela rating: Variations permitted based on LED manufacturing specifications
• Wavelength peak: Variations within red spectrum range (650nm to 660nm)
• Product status: Active status preferred over obsolete for ongoing availability

The substitute part ACSC56-41SURKWA-F01 maintains all mandatory matching parameters while offering improved product status and enhanced brightness characteristics.

Engineering Selection Recommendations

Primary Recommendation: ACSC56-41SURKWA-F01

The ACSC56-41SURKWA-F01 is the direct substitute for the obsolete ACSC56-41SRWA-F01. Selection of this substitute part is based on the following engineering criteria:

1. Product Status: The substitute part maintains Active product status, ensuring long-term component availability and supply chain continuity compared to the Obsolete status of the original part.

2. Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for electronic component manufacturing and deployment.

3. Moisture Sensitivity: Identical MSL rating (2A, 4 Weeks) ensures equivalent handling and storage requirements during manufacturing and assembly processes.

4. Mechanical Compatibility: Identical physical dimensions, package type, and SMD configuration ensure direct PCB layout compatibility without design modification.

5. Electrical Compatibility: Forward voltage variation (1.85V to 1.95V) falls within acceptable operating range for common cathode 7-segment display driver circuits. Current test specification remains constant at 20mA. Maximum power dissipation remains at 75mW.

6. Optical Performance: Enhanced brightness (44mcd versus 26mcd) provides improved visibility while maintaining wavelength within the red spectrum range (650nm versus 660nm).

Frequently Asked Questions (FAQ)

Q: Can ACSC56-41SURKWA-F01 be used as a direct replacement for ACSC56-41SRWA-F01 without circuit modification?

A: Yes. The substitute part maintains identical mechanical dimensions, package configuration, common cathode pin arrangement, and electrical test current specification. Forward voltage variation (1.95V versus 1.85V) is within acceptable tolerance for standard 7-segment display driver circuits. No PCB layout or schematic changes are required.

Q: What is the significance of the forward voltage difference between the two parts?

A: The forward voltage difference of 0.10V (1.85V to 1.95V) reflects normal manufacturing variation within red LED specifications. Both values are compatible with standard common cathode display driver circuits that typically operate at 5V or 3.3V logic levels with current-limiting resistors. Circuit design margins accommodate this variation.

Q: Why is the substitute part brighter (44mcd versus 26mcd)?

A: The increased brightness rating reflects improved LED die efficiency and manufacturing process enhancements in the active product line. This enhancement provides superior display visibility without requiring circuit modification. The identical 20mA test current and 75mW maximum power dissipation ensure thermal and electrical compatibility.

Q: Are there any handling or storage differences between the original and substitute parts?

A: No. Both parts share identical Moisture Sensitivity Level (2A, 4 Weeks) and packaging format (Tape & Reel). Storage and handling procedures remain unchanged.

Q: What is the wavelength difference between 660nm and 650nm?

A: Both wavelengths fall within the red spectrum visible range. The 10nm difference reflects manufacturing process variation and does not affect visual appearance or circuit compatibility. Human perception of red color remains consistent across this wavelength range.

Q: Is the substitute part suitable for new design applications?

A: Yes. The ACSC56-41SURKWA-F01 maintains Active product status and full regulatory compliance (ROHS3, REACH unaffected). This part is appropriate for both replacement applications and new design implementations.
