TSAL5300 Infrared Emitter 940nm Equivalent & Substitute Parts

Part Overview

The TSAL5300 is a 940nm infrared emitter manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting in radial configuration. This component operates at 100mA forward current with a 1.35V typical forward voltage and delivers 30mW/sr radiant intensity at rated current. The TSAL5300 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSAL5300 is determined by the following critical parameters: wavelength (940nm), maximum forward current (100mA), forward voltage compatibility (1.35V nominal), mounting type (through hole), and package configuration (radial, 5mm diameter). The viewing angle and radiant intensity may vary within acceptable ranges for equivalent functionality in infrared detection and transmission applications.

The identified substitute parts maintain the core electrical and mechanical specifications while differing in radiant intensity output and viewing angle characteristics. These variations are within the tolerance range for equivalent component selection in standard infrared applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete TSAL5300, the TSAL6400 from Vishay Semiconductor Opto Division is the primary substitute. Both components share identical wavelength, forward current rating, forward voltage, mounting type, and package configuration. The TSAL6400 maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The IR333/H0 from Everlight Electronics Co Ltd provides an alternative substitute with compatible wavelength, current rating, and operating temperature range. However, this component exhibits lower radiant intensity (5.6mW/sr versus 30mW/sr) and a narrower viewing angle (40° versus 44°), which may impact performance in applications requiring higher optical output or wider beam dispersion.

Selection between TSAL6400 and IR333/H0 depends on application-specific requirements for radiant intensity and viewing angle. The TSAL6400 maintains closer performance parity with the original TSAL5300 specification.

Frequently Asked Questions (FAQ)

Q: Can the TSAL6400 directly replace the TSAL5300 in existing designs?

A: Yes. The TSAL6400 maintains identical wavelength (940nm), forward current (100mA), forward voltage (1.35V), mounting type (through hole), and package configuration (radial, 5mm diameter). The primary difference is radiant intensity (25mW/sr versus 30mW/sr), which represents a 17% reduction in optical output.

Q: What are the key differences between TSAL6400 and IR333/H0?

A: Both are active 940nm infrared emitters rated for 100mA. The TSAL6400 delivers 25mW/sr radiant intensity with a 50° viewing angle, while the IR333/H0 delivers 5.6mW/sr with a 40° viewing angle. The TSAL6400 provides significantly higher optical output and wider beam dispersion.

Q: Are there compatibility concerns with the IR333/H0 substitute?

A: The IR333/H0 is mechanically and electrically compatible for through-hole mounting. However, the substantially lower radiant intensity (5.6mW/sr) may require circuit-level adjustments in applications sensitive to optical output levels. Verify that the reduced intensity meets application requirements before implementation.

Q: What compliance certifications apply to these substitute parts?

A: The TSAL5300 and TSAL6400 are both ROHS3 compliant. Both are classified as REACH Unaffected and carry ECCN EAR99 designation. Compliance documentation for the IR333/H0 was not provided in the available specifications.

Q: Does viewing angle variation affect substitution suitability?

A: Viewing angle differences (44° for TSAL5300, 50° for TSAL6400, 40° for IR333/H0) may impact beam dispersion characteristics. Applications requiring specific angular coverage should evaluate whether the substitute's viewing angle meets optical design requirements.
