Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5862401205 are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T - 3 1/4
• Color: Red
• Voltage - Forward (Vf): 28V
• Configuration: Single

Substitution Categories:

Direct Manufacturer Equivalent (5862401205F): Identical electrical and mechanical specifications to the main part. Same series (586), same wavelength (630nm), same millicandela rating (525mcd). Differs only in packaging (Bulk vs. standard) and product status (Active vs. Obsolete).

Parametric Equivalents (5855215F, 5855225F, 5855256F): These parts share the same base type, size, color, voltage, and configuration as the main part. They differ in wavelength (660nm vs. 630nm) and millicandela rating (560mcd vs. 525mcd). All are from the 585 series and maintain active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

5862401205F (Direct Equivalent): This part is the primary substitute for the obsolete 5862401205. It maintains identical electrical and optical specifications (630nm wavelength, 525mcd rating) and is currently in active production status. ROHS3 compliance and bulk packaging make this the preferred choice for new designs and ongoing production requirements.

5855215F, 5855225F, 5855256F (Parametric Equivalents): These parts are suitable substitutes when the wavelength shift from 630nm to 660nm and the increased brightness (560mcd vs. 525mcd) are acceptable within system design tolerances. All three maintain the same base type, size, voltage, and configuration. All are ROHS3 compliant and in active production status. Selection among these three should be based on packaging requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5862401205F be used as a direct replacement for 5862401205? A: Yes. The 5862401205F is electrically and optically identical to the main part, differing only in packaging format and product status. The 5862401205F is in active production.

Q: What is the difference between 5862401205 and the 585x series substitutes? A: The primary differences are wavelength (630nm vs. 660nm) and brightness (525mcd vs. 560mcd). Both wavelengths produce red light visible to the human eye. The 585x series parts deliver approximately 7% higher brightness. All parts share identical base type, size, voltage, and configuration.

Q: Are all substitute parts ROHS3 compliant? A: The 5862401205F, 5855215F, 5855225F, and 5855256F are all ROHS3 compliant. The original 5862401205 does not specify RoHS status.

Q: What is the packaging difference between the main part and substitutes? A: The original 5862401205 uses standard packaging. The substitute parts (5862401205F, 5855215F, 5855225F, 5855256F) are supplied in bulk packaging.

Q: Can 5855256F be used interchangeably with 5855215F and 5855225F? A: Yes, from an electrical and mechanical standpoint. All three parts share identical base type, size, voltage, wavelength (660nm), brightness (560mcd), and configuration. Selection should be based on availability and packaging requirements.

Q: Are there any voltage compatibility concerns with these substitutes? A: No. All substitute parts are rated for 28V forward voltage, matching the original 5862401205 specification.
