SA04-12YWA Equivalent & Substitute Parts

Part Overview

The SA04-12YWA is a 7-segment LED display module manufactured by Kingbright, featuring a single yellow character with 0.40" digit height in a 10-DIP package configuration. This display operates as a common anode device with a forward voltage of 2.1V and test current of 20mA. The product is currently active and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that maintain functional and electrical compatibility within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA04-12YWA is determined by the following critical parameters:

Mandatory Matching Criteria:

• Display Type: 7-Segment
• Number of Characters: 1
• Digit/Alpha Size: 0.40" (10.16mm)
• Common Pin Configuration: Common Anode
• Package Type: 10-DIP

Allowable Variation Parameters:

• Forward Voltage (Vf): ±0.1V tolerance acceptable
• Test Current: 20mA fixed requirement
• Color: Yellow or Yellow-Green (within visible spectrum compatibility)
• Millicandela Rating: Higher brightness acceptable
• Wavelength - Peak: 572nm to 590nm range acceptable
• Power Dissipation: Within maximum rating of 75mW
• Physical Dimensions: Minor variations acceptable within DIP package standard

The INND-TS40YGAB substitute part meets all mandatory matching criteria and operates within allowable variation parameters for electrical and optical characteristics.

Engineering Selection Recommendations

SA04-12YWA (Kingbright) - Primary Selection

Use the SA04-12YWA when yellow color specification (590nm wavelength) is a design requirement. This part is actively manufactured and maintains full RoHS3 compliance. The 6.3mcd brightness rating is suitable for standard display applications with typical ambient lighting conditions.

INND-TS40YGAB (Inolux) - Substitute Selection

The INND-TS40YGAB serves as a direct functional substitute when SA04-12YWA availability is constrained. This part maintains identical 7-segment, single-character, 0.40" format with common anode configuration. The forward voltage differential of 0.1V (2.0V vs. 2.1V) is within standard circuit design tolerance and requires no modification to existing current-limiting resistor calculations. The higher millicandela rating (15mcd vs. 6.3mcd) provides increased brightness margin without exceeding maximum power dissipation limits. The yellow-green color (572nm) represents a minor spectral shift within the yellow family and is visually compatible with standard yellow display applications. Both parts carry identical RoHS3 compliance and active product status.

Compliance Verification

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.41.0000. Moisture sensitivity level (MSL 1) is unlimited for both components, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the INND-TS40YGAB replace the SA04-12YWA in existing circuit designs without modification?

A: Yes. Both parts operate at 20mA test current with forward voltages within 0.1V tolerance (2.1V vs. 2.0V). Standard current-limiting resistor calculations remain valid. The 10-DIP package pinout is identical, enabling direct socket substitution.

Q: What is the visual difference between the yellow SA04-12YWA and yellow-green INND-TS40YGAB?

A: The SA04-12YWA emits at 590nm (pure yellow), while the INND-TS40YGAB emits at 572nm (yellow-green). Both colors fall within the yellow spectrum family. The INND-TS40YGAB appears slightly more green-tinted under observation. Color perception depends on ambient lighting and observer sensitivity.

Q: Is the higher brightness of the INND-TS40YGAB (15mcd vs. 6.3mcd) a concern for circuit compatibility?

A: No. Higher brightness does not create compatibility issues. The 15mcd rating is achieved within the same 20mA test current and 70mW maximum power dissipation, both within or below the SA04-12YWA specifications. Circuit operation remains unchanged.

Q: Are there physical dimension differences between these parts?

A: Minor differences exist within standard DIP package tolerance. The SA04-12YWA measures 0.738" H x 0.386" W x 0.200" D, while the INND-TS40YGAB measures 0.508" H x 0.379" W x 0.250" D. Both fit standard 10-DIP sockets. The height difference reflects different internal LED die positioning but does not affect PCB mounting or electrical function.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both parts carry MSL 1 (unlimited) moisture sensitivity rating, indicating no special moisture control or baking requirements. Standard component storage at room temperature and normal humidity is acceptable for both parts.

Q: What is the packaging difference between these parts?

A: The SA04-12YWA is supplied in standard packaging (not specified), while the INND-TS40YGAB is supplied in tube packaging. This affects only receiving, storage, and handling logistics and does not impact electrical or functional performance.

Q: Are both parts suitable for long-term production use?

A: Yes. Both parts maintain active product status with full RoHS3 compliance and REACH unaffected designation, indicating ongoing manufacturer support and regulatory compliance for current and future production applications.
