APA3010EC Red Surface Mount LED - Equivalent & Substitute Parts

Part Overview

The APA3010EC is a red surface mount light-emitting diode manufactured by Kingbright, designed for indication applications in discrete 2V configurations. This 2-SMD, no-lead component features a clear lens with a rectangle domed top profile and operates at 20mA test current with a dominant wavelength of 625nm. The part is currently in active production status with ROHS3 compliance and is available in tape and reel packaging.

Substitute parts become necessary when the primary APA3010EC experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APA3010EC are classified based on strict adherence to the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Red
• Mounting Type: Surface Mount, Right Angle
• Package / Case: 2-SMD, No Lead
• Voltage - Forward (Vf) (Typ): 2V
• Current - Test: 20mA
• Lens Size: 2.00mm x 1.00mm
• Height (Max): 1.00mm
• Size / Dimension: 3.00mm L x 2.00mm W

Parametric Equivalent Classification: Parts meeting all primary compatibility criteria with identical electrical and mechanical specifications are classified as parametric equivalents. The APA3010EC-GX from Kingbright falls into this category.

Similar Part Classification: Parts that share the same color, mounting type, package configuration, forward voltage, test current, lens size, and physical dimensions but differ in wavelength, millicandela rating, viewing angle, or product status are classified as similar parts. These include BR1101F-TR, HSMC-C680, HSMS-C680, and LTST-S321KRKT.

Parameter Comparison

Engineering Selection Recommendations

APA3010EC-GX (Kingbright): This part is the direct parametric equivalent to the APA3010EC. All electrical and mechanical specifications are identical, including forward voltage, test current, wavelength, millicandela rating, and physical dimensions. Both parts are in active production status with ROHS3 compliance and identical moisture sensitivity levels. This substitute provides the highest level of functional interchangeability.

LTST-S321KRKT (Lite-On Inc.): This part maintains compatibility across all critical parameters: 2V forward voltage, 20mA test current, 2-SMD no-lead package, and identical physical dimensions. The dominant wavelength of 631nm is within the red spectrum range. The part is in active production status with ROHS3 compliance and identical MSL rating. The millicandela rating of 54mcd exceeds the APA3010EC specification of 15mcd, and the viewing angle of 130° is slightly wider than 120°.

HSMC-C680 (Broadcom Limited): This part shares the same forward voltage, test current, package configuration, and physical height. The dominant wavelength of 630nm is within acceptable red spectrum parameters. The part is in active production status with ROHS3 compliance. The millicandela rating of 62.3mcd is significantly higher than the APA3010EC. The physical width dimension is 1.00mm compared to 2.00mm for the APA3010EC. The MSL rating of 2A (4 Weeks) provides superior moisture protection compared to the APA3010EC MSL 3 rating.

HSMS-C680 (Broadcom Limited): This part maintains 2V forward voltage, 20mA test current, and identical package specifications. The dominant wavelength of 621nm is within the red spectrum. The part is in active production status with ROHS3 compliance. The millicandela rating of 5.1mcd is lower than the APA3010EC specification of 15mcd. The physical width dimension is 1.00mm compared to 2.00mm for the APA3010EC. The MSL rating of 2A (4 Weeks) provides superior moisture protection.

BR1101F-TR (Stanley Electric Co): This part is classified as obsolete and carries a forward voltage of 1.7V, which differs from the APA3010EC specification of 2V. The dominant wavelength of 647nm represents a shift toward the far-red spectrum. The millicandela rating of 12.4mcd is lower than the APA3010EC. The MSL rating of 4 (72 Hours) indicates lower moisture tolerance compared to the APA3010EC MSL 3 rating. The obsolete product status and electrical parameter differences limit its suitability as a primary substitute.

Frequently Asked Questions (FAQ)

Q: Can APA3010EC-GX be used as a direct replacement for APA3010EC?

A: Yes. The APA3010EC-GX is a parametric equivalent with identical specifications across all electrical and mechanical parameters. Both parts share the same 2V forward voltage, 20mA test current, 625nm dominant wavelength, 15mcd millicandela rating, and 3.00mm L x 2.00mm W physical dimensions. Both are in active production status with ROHS3 compliance and identical MSL ratings.

Q: What are the key differences between the APA3010EC and LTST-S321KRKT?

A: The LTST-S321KRKT maintains compatibility in forward voltage (2V), test current (20mA), package type (2-SMD, no-lead), and physical dimensions (3.00mm L x 2.00mm W). The primary differences are the dominant wavelength (631nm versus 625nm), millicandela rating (54mcd versus 15mcd), and viewing angle (130° versus 120°). The LTST-S321KRKT provides higher brightness output.

Q: Why do HSMC-C680 and HSMS-C680 have different physical width dimensions?

A: Both Broadcom parts are listed with 3.00mm L x 1.00mm W dimensions, compared to the APA3010EC dimension of 3.00mm L x 2.00mm W. This dimensional difference may affect PCB layout compatibility and should be verified against specific board design requirements before substitution.

Q: Is BR1101F-TR suitable as a substitute for APA3010EC?

A: BR1101F-TR is classified as obsolete and carries a forward voltage of 1.7V, which differs from the APA3010EC specification of 2V. The obsolete status and electrical parameter variance make this part unsuitable as a primary substitute. Active production alternatives are preferred.

Q: What does MSL rating mean in the context of these LED parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions of 30°C and 85% relative humidity before soldering. The APA3010EC carries MSL 3 (168 Hours), while HSMC-C680 and HSMS-C680 carry MSL 2A (4 Weeks), indicating superior moisture tolerance. BR1101F-TR carries MSL 4 (72 Hours), indicating lower moisture tolerance.

Q: Can I substitute based on wavelength alone?

A: No. While all substitute parts are red LEDs, wavelength is only one parameter. Substitution requires compatibility across multiple parameters including forward voltage, test current, package configuration, physical dimensions, and product status. The APA3010EC-GX is the only true parametric equivalent with identical specifications across all parameters.

Q: What is the significance of the "Active" versus "Obsolete" product status?

A: Active status indicates the part is currently in production and available for new designs. Obsolete status indicates the manufacturer has discontinued production. For new designs and long-term supply assurance, active status parts are preferred. BR1101F-TR's obsolete status limits its suitability for new applications.

Q: How do millicandela ratings affect substitution decisions?

A: Millicandela (mcd) rating indicates LED brightness. The APA3010EC is rated at 15mcd. LTST-S321KRKT (54mcd) and HSMC-C680 (62.3mcd) provide higher brightness, while HSMS-C680 (5.1mcd) provides lower brightness. Higher brightness may affect circuit design and current limiting requirements. Application-specific brightness requirements must be considered.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including the APA3010EC and all substitutes, carry ROHS3 compliance certification. This ensures compliance with Restriction of Hazardous Substances regulations across all options.
