Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OVSAGBC2R8 are identified based on the following critical parameters:

• Color and Wavelength: Green LED indication (527nm dominant wavelength)
• Electrical Characteristics: Forward voltage range 3.6V–3.9V, test current 30mA
• Optical Performance: Brightness rating (700mcd–1800mcd), 120° viewing angle
• Mechanical Compatibility: Surface mount 4-PLCC package, dimensions 3.20mm L x 2.80mm W, height ≤2.10mm
• Regulatory Compliance: ROHS3 compliant, REACH unaffected, EAR99 classification
• Product Status: Active alternatives preferred for obsolete part replacement

Two substitute parts meet these criteria:

1. OVSA1GBC2R8 (TT Electronics/Optek Technology) – Manufacturer-recommended substitute with improved brightness (1800mcd) and lower forward voltage (3.6V)
2. HSMM-A400-U4QM2 (Broadcom Limited) – Parametric equivalent with comparable electrical and optical characteristics

Parameter Comparison

Engineering Selection Recommendations

OVSA1GBC2R8 is the manufacturer-recommended substitute for OVSAGBC2R8. Both parts are manufactured by TT Electronics/Optek Technology and maintain identical wavelength (527nm), viewing angle (120°), and test current (30mA) specifications. OVSA1GBC2R8 is active in production with higher brightness output (1800mcd versus 700mcd) and lower forward voltage (3.6V versus 3.9V), reducing power consumption in LED indication circuits. The package configuration differs (4-SMD, J-Lead versus 4-PLCC), requiring PCB layout verification. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

HSMM-A400-U4QM2 (Broadcom Limited) serves as a parametric equivalent for applications requiring identical 4-PLCC package geometry. This part maintains the same dominant wavelength range (525nm versus 527nm), forward voltage (3.8V), test current (30mA), and viewing angle (120°). Brightness output (788mcd) closely matches the original specification. The primary distinction is improved moisture sensitivity (2A, 4 Weeks versus 5A, 24 Hours), beneficial for high-humidity storage and assembly environments. Maximum height increases to 2.10mm, requiring clearance verification in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can OVSA1GBC2R8 directly replace OVSAGBC2R8 without PCB modification?

A: OVSA1GBC2R8 uses a 4-SMD, J-Lead package configuration compared to the original 4-PLCC package. While dimensions are similar (3.20mm L x 2.70mm W versus 3.20mm L x 2.80mm W), the lead geometry differs. PCB footprint verification is required before implementation.

Q: What is the wavelength difference between OVSAGBC2R8 and HSMM-A400-U4QM2?

A: OVSAGBC2R8 has a dominant wavelength of 527nm, while HSMM-A400-U4QM2 is specified at 525nm. This 2nm difference falls within the green LED spectrum and is imperceptible to human vision in indication applications.

Q: Does HSMM-A400-U4QM2 fit the same PCB footprint as OVSAGBC2R8?

A: Yes. Both parts use the 4-PLCC package with identical dimensions (3.20mm L x 2.80mm W). HSMM-A400-U4QM2 has a maximum height of 2.10mm versus 1.95mm for OVSAGBC2R8, requiring clearance verification in designs with height constraints.

Q: Which substitute part has better moisture sensitivity performance?

A: HSMM-A400-U4QM2 has superior moisture sensitivity (MSL 2A, 4 Weeks) compared to both OVSAGBC2R8 and OVSA1GBC2R8 (MSL 5A, 24 Hours). This provides extended shelf life and reduced risk of moisture-induced failures in humid environments.

Q: Are all three parts ROHS3 compliant?

A: Yes. OVSAGBC2R8, OVSA1GBC2R8, and HSMM-A400-U4QM2 are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is the brightness difference between the substitute parts?

A: OVSA1GBC2R8 provides 1800mcd (2.57x brighter than original), while HSMM-A400-U4QM2 provides 788mcd (1.13x brighter than original). Circuit design must account for increased brightness in OVSA1GBC2R8 applications to prevent over-illumination.
