Equivalent & Substitute Parts for AN5307B Infrared Emitter

Part Overview

The AN5307B is an infrared (IR) emitter manufactured by Stanley Electric Co, designed for through-hole mounting applications requiring 940nm wavelength emission. This component operates at 1.3V forward voltage with a maximum DC forward current of 100mA and delivers 8.4mW/sr radiant intensity at 50mA with a 38° viewing angle.

The AN5307B carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AN5307B is determined by strict alignment with the following critical parameters:

Primary Matching Criteria:

• Wavelength: 940nm (exact match required)
• Current - DC Forward (If) Max: 100mA (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Orientation: Top View (exact match required)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) Typical: 1.3V nominal (tolerance range acceptable)
• Radiant Intensity (Ie) Min @ If: minimum 8.4mW/sr @ 50mA (equal or greater acceptable)
• Viewing Angle: 38° nominal (narrower angles acceptable for directional applications)
• Operating Temperature Range: must encompass or exceed -30°C to 85°C

Both identified substitute parts meet all primary matching criteria and demonstrate compatibility within secondary parameters.

Engineering Selection Recommendations

15400594A3590 (Würth Elektronik WL-TIRW Series)

This substitute demonstrates active product status with ROHS3 compliance. The component matches the AN5307B across all primary criteria with identical forward current and voltage specifications. Radiant intensity exceeds the minimum requirement at 10mW/sr versus 8.4mW/sr. The viewing angle of 35° is narrower than the original 38°, which may affect beam spread characteristics in applications requiring wider angular distribution. Operating temperature range extends to -40°C, providing enhanced low-temperature performance. Current inventory availability is 1998 units.

BIR-BM53E4G-2 (American Bright Optoelectronics BIR-BM53 Series)

This substitute carries active product status with ROHS3 compliance. The component satisfies all primary matching criteria with identical forward current specification. Forward voltage is 1.25V, representing a 0.05V reduction from the AN5307B nominal 1.3V. Radiant intensity significantly exceeds the minimum requirement at 19.42mW/sr, providing enhanced optical output. The viewing angle of 30° is substantially narrower than the original 38°, resulting in more focused beam characteristics. Operating temperature range extends to -40°C. Current inventory availability is 7693 units.

Both substitutes provide compliance with current regulatory standards and active manufacturing status, addressing the obsolescence of the original AN5307B component.

Frequently Asked Questions (FAQ)

Q: Can the 15400594A3590 directly replace the AN5307B in existing designs?

A: The 15400594A3590 matches all primary electrical and mechanical parameters. The 35° viewing angle versus the original 38° represents a 3° reduction in beam spread. Applications requiring the full 38° angular distribution should evaluate whether the narrower beam is acceptable for the specific optical design.

Q: What is the significance of the radiant intensity difference between substitutes?

A: The AN5307B specifies 8.4mW/sr minimum at 50mA. The 15400594A3590 delivers 10mW/sr, and the BIR-BM53E4G-2 delivers 19.42mW/sr. Higher radiant intensity indicates greater optical output. Applications with fixed optical receiver sensitivity may require circuit adjustment if substituting to the BIR-BM53E4G-2 due to the significantly increased output.

Q: Are there temperature range considerations for substitution?

A: The AN5307B operates from -30°C to 85°C. Both substitutes extend the lower operating limit to -40°C, providing enhanced cold-temperature performance. The upper limit remains 85°C for all three components. Applications operating below -30°C benefit from the extended range of substitute parts.

Q: How do forward voltage differences affect circuit design?

A: The AN5307B and 15400594A3590 both specify 1.3V typical forward voltage. The BIR-BM53E4G-2 specifies 1.25V, a 0.05V reduction. For current-limiting resistor calculations, this difference is minor but should be verified in designs with tight voltage margin specifications.

Q: What packaging considerations apply to these radial through-hole components?

A: All three components utilize radial through-hole packaging with identical mechanical form factors. PCB layout and mounting procedures remain unchanged during substitution. Verify lead spacing and hole diameter compatibility with existing PCB designs.

Q: Which substitute offers the best availability?

A: The BIR-BM53E4G-2 currently maintains the highest inventory at 7693 units. The 15400594A3590 provides 1998 units. Both substitutes demonstrate active product status with ongoing manufacturing support, contrasting with the obsolete AN5307B.
