Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE3455-001 is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 935nm (exact match required)
• Type: Infrared (IR) Emitter
• Mounting Type: Through Hole
• Orientation: Top View

Secondary Compatibility Parameters:

• Current - DC Forward (If) (Max): 100mA or greater
• Voltage - Forward (Vf) (Typ): Within acceptable circuit design tolerance
• Viewing Angle: 90° preferred for direct replacement
• Package / Case: TO-46-2 Metal Can preferred; alternative packages acceptable if mechanical fit permits
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• RoHS Compliance: Required for regulatory alignment

Two substitute parts meet the wavelength and functional requirements:

OP130W (TT Electronics/Optek Technology): Matches wavelength (935nm), current rating (100mA), package (TO-46-2 Metal Can), and viewing angle (50°). Forward voltage is 1.75V. Operating temperature range is -65°C ~ 125°C. Product status is Active.

OP165W (TT Electronics/Optek Technology): Matches wavelength (935nm), package type (through-hole), and viewing angle (90°). Current rating is 50mA (lower than SE3455-001). Forward voltage is 1.6V. Package is T-1 (different from TO-46-2). Operating temperature range is -40°C ~ 100°C. Product status is Active.

Parameter Comparison

Engineering Selection Recommendations

OP130W Selection Criteria:

The OP130W is the closest functional equivalent to the SE3455-001. Both components share identical wavelength (935nm), maximum forward current (100mA), package type (TO-46-2 Metal Can), and mounting configuration (through-hole). The forward voltage differential (1.75V vs. 1.7V) is 0.05V, which is within typical circuit design tolerance. The OP130W viewing angle is 50° compared to the SE3455-001's 90°, representing a narrower emission pattern. The OP130W operating temperature range (-65°C ~ 125°C) exceeds the SE3455-001 specification (-55°C ~ 125°C), providing extended low-temperature capability. The OP130W holds Active product status and ROHS3 compliance, ensuring ongoing availability and regulatory alignment.

OP165W Selection Criteria:

The OP165W is a secondary substitute option with matching wavelength (935nm), viewing angle (90°), and through-hole mounting. However, the OP165W maximum forward current is 50mA, which is 50% lower than the SE3455-001's 100mA rating. This current limitation restricts the OP165W to applications requiring lower emission intensity. The OP165W package is T-1 (different from TO-46-2 Metal Can), requiring mechanical redesign or adapter consideration. The operating temperature range (-40°C ~ 100°C) is narrower than the SE3455-001, with a lower maximum temperature (100°C vs. 125°C). The OP165W is suitable only for applications where reduced current and narrower temperature range are acceptable.

Compliance and Availability:

Both substitute parts are ROHS3 compliant and carry REACH Unaffected status, meeting current regulatory requirements. Both are classified as Active products with documented inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the OP130W directly replace the SE3455-001 without circuit modification?

A: The OP130W is mechanically and electrically compatible with the SE3455-001 in most applications. Both use TO-46-2 Metal Can packaging and support 100mA forward current. The forward voltage difference (1.75V vs. 1.7V) is 0.05V and typically accommodated by standard circuit design margins. The primary difference is viewing angle (50° vs. 90°), which affects the spatial distribution of infrared emission. Applications requiring the full 90° emission pattern must account for the OP130W's narrower 50° angle.

Q: Why is the OP165W current rating lower than the SE3455-001?

A: The OP165W is designed for lower-power applications with a maximum forward current of 50mA, compared to the SE3455-001's 100mA. This is a fundamental design characteristic of the OP165W and reflects its intended application range. The OP165W is not suitable for circuits designed to operate the SE3455-001 at full 100mA current.

Q: What is the impact of the OP130W's 50° viewing angle versus the SE3455-001's 90° angle?

A: Viewing angle determines the spatial distribution of infrared emission. The SE3455-001's 90° angle provides a wider emission cone, distributing light across a broader area. The OP130W's 50° angle concentrates emission into a narrower cone, resulting in higher intensity within that cone but reduced coverage outside it. Applications using proximity sensors, optical communication, or wide-area detection may require the 90° pattern. Applications using focused beam or narrow-angle detection can utilize the OP130W's 50° pattern.

Q: Are both substitute parts RoHS compliant?

A: Yes. The SE3455-001 is RoHS Compliant. Both OP130W and OP165W are ROHS3 Compliant, which represents the current RoHS standard. ROHS3 compliance encompasses RoHS requirements and is suitable for new designs and legacy system updates.

Q: What is the temperature range difference between the SE3455-001 and OP165W?

A: The SE3455-001 operates from -55°C to 125°C. The OP165W operates from -40°C to 100°C. The OP165W has a narrower range, with a higher minimum temperature (-40°C vs. -55°C) and lower maximum temperature (100°C vs. 125°C). Applications requiring operation below -40°C or above 100°C cannot use the OP165W.

Q: Can the OP165W be used in a circuit designed for the SE3455-001?

A: The OP165W can be used only if the application circuit is redesigned to accommodate its 50mA maximum current (versus 100mA for SE3455-001) and its T-1 package (versus TO-46-2 Metal Can). The narrower operating temperature range (-40°C ~ 100°C) must also be verified as acceptable for the intended application. Mechanical mounting changes are required due to package differences.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These components do not require special moisture-controlled storage, handling, or baking procedures prior to soldering. All three parts (SE3455-001, OP130W, OP165W) carry MSL 1 rating.
