Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5973301202F is determined by the following critical parameters: wavelength range (green spectrum 560-572nm), forward voltage compatibility (2.0-2.1V), surface mount package type (2-PLCC or equivalent 2-SMD), 120° viewing angle, and RoHS3 compliance. Parts meeting these criteria can function as direct replacements in LED indication circuits. The substitute parts identified are grouped as follows:

Direct Manufacturer Equivalent: Dialight 5973301202NF maintains identical electrical specifications and package compatibility while offering higher brightness (98mcd) and active product status.

Cross-Manufacturer Alternative: Vishay VLMP3102-GS08 provides functional equivalence with minor parameter variations within acceptable tolerance for green LED indication applications, including slightly different wavelength peak (555nm vs 572nm) and reduced brightness (4.95mcd).

Parameter Comparison

Engineering Selection Recommendations

Dialight 5973301202NF is the primary substitute for the obsolete 5973301202F. Both parts are manufactured by Dialight, maintain identical forward voltage (2V) and viewing angle (120°), and share the same 2-PLCC package footprint. The 5973301202NF is currently in active production status with higher brightness output (98mcd vs 19.6mcd), making it suitable for applications where increased luminous intensity is acceptable. Both parts are RoHS3 compliant with identical moisture sensitivity levels.

Vishay VLMP3102-GS08 serves as a cross-manufacturer alternative when Dialight parts are unavailable. This part maintains green wavelength output (560nm dominant), 120° viewing angle, and surface mount configuration. The forward voltage is marginally higher at 2.1V, and brightness is significantly lower at 4.95mcd. The package designation differs (2-SMD, J-Lead vs 2-PLCC), though both are surface mount compatible. This part is active in production and RoHS3 compliant. Selection of this alternative requires circuit-level evaluation of voltage tolerance and brightness requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5973301202NF directly replace the obsolete 5973301202F without circuit modifications?

A: Yes. Both parts share identical forward voltage (2V), current rating (10mA), viewing angle (120°), and 2-PLCC package footprint. The primary difference is increased brightness (98mcd vs 19.6mcd), which does not require circuit changes but may alter visual indication intensity.

Q: What are the key differences between the Dialight and Vishay substitutes?

A: The Dialight 5973301202NF maintains exact electrical and package compatibility. The Vishay VLMP3102-GS08 differs in forward voltage (2.1V vs 2V), brightness (4.95mcd vs 19.6mcd), package type (2-SMD, J-Lead vs 2-PLCC), and wavelength peak (555nm vs 572nm). The Vishay part requires evaluation for circuit compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both the Dialight 5973301202NF and Vishay VLMP3102-GS08 are RoHS3 compliant and REACH unaffected, matching the compliance status of the original 5973301202F.

Q: Does the package difference between 2-PLCC and 2-SMD, J-Lead affect PCB compatibility?

A: Package footprints differ between 2-PLCC and 2-SMD, J-Lead configurations. PCB layout and solder pad design must accommodate the specific package type. Verify footprint compatibility before selecting the Vishay alternative.

Q: What is the brightness difference between substitutes, and does it matter for indication applications?

A: The 5973301202NF provides 98mcd (5x brighter than original), while the VLMP3102-GS08 provides 4.95mcd (0.25x original brightness). Selection depends on application requirements for visual indication intensity and ambient lighting conditions.
