Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH 4045N E9607 is determined by the following critical parameters:

Core Electrical Parameters:

• Wavelength: 950nm (exact match required)
• Maximum DC Forward Current: 70mA (exact match required)
• Forward Voltage: 1.5V nominal (primary specification)
• Viewing Angle: 18° (exact match required)

Physical & Environmental Parameters:

• Mounting Type: Surface Mount, Right Angle (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

Substitute parts must maintain identical electrical performance characteristics and environmental ratings. Package configuration differences are evaluated based on circuit board layout compatibility and mechanical fit requirements.

Engineering Selection Recommendations

SFH 4045N (Tape & Reel Packaging): This part is the primary active substitute for the obsolete SFH 4045N E9607. It maintains identical electrical specifications including 950nm wavelength, 70mA maximum forward current, 18° viewing angle, and -40°C ~ 85°C operating temperature range. The forward voltage is specified at 1.6V (compared to 1.5V nominal for the main part), representing a 0.1V increase within typical component tolerance ranges. The package configuration differs (2-SMD No Lead versus 2-SMD Flat Lead), requiring circuit board layout verification for mechanical compatibility. This part carries Active product status and ROHS3 compliance certification. Tape & Reel packaging is suitable for high-volume production environments.

SFH 4045N R33: This part provides an alternative substitute maintaining the original 1.5V forward voltage specification and 2-SMD flat lead package configuration identical to the main part. All electrical parameters match the SFH 4045N E9607, including 950nm wavelength, 70mA maximum forward current, 18° viewing angle, and -40°C ~ 85°C operating temperature range. This part carries Active product status and ROHS3 compliance certification. The flat lead package eliminates the need for circuit board layout modifications compared to the original design. This configuration is suitable for applications requiring direct package compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the SFH 4045N (Tape & Reel) be used as a direct replacement for the SFH 4045N E9607?

A: The SFH 4045N provides electrical equivalence with identical wavelength (950nm), forward current (70mA), viewing angle (18°), and operating temperature range (-40°C ~ 85°C). The primary difference is package configuration: 2-SMD No Lead versus 2-SMD Flat Lead. Circuit board layout compatibility must be verified before implementation.

Q: What is the significance of the forward voltage difference between SFH 4045N E9607 (1.5V) and SFH 4045N (1.6V)?

A: The 0.1V difference falls within standard component manufacturing tolerances for infrared emitters. Both specifications are within the same operational envelope and do not affect functional performance in typical circuit applications.

Q: Is the SFH 4045N R33 identical to the original SFH 4045N E9607?

A: The SFH 4045N R33 maintains identical electrical specifications and package configuration (2-SMD Flat Lead) as the SFH 4045N E9607. Both operate at 950nm wavelength with 70mA maximum forward current and 1.5V nominal forward voltage. The primary distinction is product status: SFH 4045N R33 is Active while SFH 4045N E9607 is Obsolete.

Q: What does the "No Lead" designation mean for the SFH 4045N?

A: The 2-SMD No Lead package configuration indicates the component uses a leadless surface mount design. This differs from the Flat Lead configuration, which includes small lead extensions. The No Lead design may require different PCB pad layouts and soldering profiles.

Q: Are all three parts ROHS3 compliant?

A: Yes. The SFH 4045N E9607, SFH 4045N, and SFH 4045N R33 are all ROHS3 Compliant, meeting environmental and hazardous substance restrictions.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: All three parts carry MSL 3 (168 Hours) rating, indicating they require controlled moisture exposure during storage and handling. Components must be stored in dry conditions and used within 168 hours of package opening under standard humidity conditions.

Q: Which substitute part should be selected for new production designs?

A: Selection depends on packaging requirements. For designs requiring the original flat lead configuration, use SFH 4045N R33. For high-volume production with tape & reel packaging, use SFH 4045N. Both are Active products with full ROHS3 compliance.
