LT A6SG-V2AB-35-0-20-R33-Z Equivalent & Substitute Parts

Part Overview

The LT A6SG-V2AB-35-0-20-R33-Z is a green LED indication component manufactured by ams-OSRAM USA INC. in the SIDELED® series. This surface-mount, right-angle LED features a 528nm dominant wavelength with 1350mcd luminous intensity and operates at 3.2V forward voltage with a 20mA test current. The component is housed in a 2-SMD Boomerang package with a 2.40mm diameter round lens and flat top design.

The product status is listed as Obsolete, necessitating identification of equivalent substitute components that maintain functional and mechanical compatibility for ongoing production, repair, and design continuity applications.

Parameter Comparison

Engineering Selection Recommendations

The AA4040ZGS/G from Kingbright is a direct functional substitute for the obsolete LT A6SG-V2AB-35-0-20-R33-Z. Both components share identical electrical specifications (3.2V forward voltage, 20mA test current), mechanical form factors (2-SMD Boomerang package, 4.00mm L x 3.60mm W dimensions), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The AA4040ZGS/G demonstrates superior availability with 14,277 pieces in stock compared to the original part's 1,006 pieces, and maintains Active product status. The substitute exhibits a marginal increase in luminous intensity (1400mcd versus 1350mcd) and a minor wavelength shift (525nm dominant versus 528nm), both within acceptable tolerances for green LED indication applications. The maximum height differential of 0.10mm (4.10mm versus 4.20mm) presents no mechanical constraint for standard PCB assembly processes.

The substitute part is supplied in Tape & Reel packaging format, standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the AA4040ZGS/G replace the LT A6SG-V2AB-35-0-20-R33-Z in existing designs without PCB modification?

A: Yes. Both components share identical mounting type (Surface Mount, Right Angle), package configuration (2-SMD Boomerang), physical dimensions (4.00mm L x 3.60mm W), and electrical specifications (3.2V forward voltage, 20mA test current). No PCB layout changes are required.

Q: What is the wavelength difference between these two parts?

A: The dominant wavelength differs by 3nm (528nm for the original versus 525nm for the substitute). This 0.57% variance is imperceptible in green LED indication applications and does not affect functional performance.

Q: How does the luminous intensity compare?

A: The AA4040ZGS/G provides 1400mcd compared to the original 1350mcd, representing a 3.7% increase in brightness. This enhancement is beneficial for visibility in indication applications.

Q: Are there height constraints for the substitute part?

A: The AA4040ZGS/G has a maximum height of 4.10mm versus 4.20mm for the original part. This 0.10mm reduction presents no assembly or clearance issues for standard PCB designs.

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: The original part carries MSL 2 (1 Year shelf life), while the substitute carries MSL 3 (168 Hours shelf life). Both ratings are within acceptable ranges for standard component storage and handling procedures.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LT A6SG-V2AB-35-0-20-R33-Z and AA4040ZGS/G are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What packaging format is the substitute supplied in?

A: The AA4040ZGS/G is supplied in Tape & Reel (TR) format, standard for automated assembly and high-volume production environments.
