Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE5450-013 are identified based on the following critical electrical and mechanical parameters:

Core Compatibility Criteria:

• Wavelength: 935nm (exact match required)
• Current - DC Forward (If) Max: 100mA (exact match required)
• Package / Case: TO-46-2 Metal Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Orientation: Top View (exact match required)

Allowable Parameter Variations:

• Voltage - Forward (Vf) Typical: ±0.05V tolerance acceptable
• Radiant Intensity (Ie) Min @ If: Higher values acceptable (1mW/cm² minimum baseline)
• Viewing Angle: ±2° variation acceptable
• Operating Temperature Range: Extended lower temperature limit acceptable

The substitute parts OP130, OP132, and OP133 (all manufactured by TT Electronics/Optek Technology) meet the core compatibility criteria. These parts maintain identical wavelength, forward current rating, and package specifications while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

OP130 Selection Criteria: OP130 provides direct functional equivalence to SE5450-013 with matching radiant intensity specification (1mW/cm² @ 100mA). This part is recommended for applications requiring minimum optical output performance. OP130 carries active product status and ROHS3 compliance certification, ensuring long-term supply availability and regulatory alignment.

OP132 Selection Criteria: OP132 delivers 4mW/cm² radiant intensity, representing a 4x increase over the SE5450-013 baseline specification. This part is suitable for applications where enhanced optical output is beneficial or where the original design margin permits higher intensity operation. Active product status and ROHS3 compliance are confirmed.

OP133 Selection Criteria: OP133 provides the highest radiant intensity at 5mW/cm² @ 100mA, representing a 5x increase over SE5450-013. This part is applicable to designs requiring maximum optical output within the 100mA current constraint. Active product status and ROHS3 compliance are confirmed.

Voltage and Temperature Considerations: All substitute parts operate at 1.75V typical forward voltage, representing a 0.05V increase from the SE5450-013 specification. This variation remains within standard component tolerance ranges. All substitutes extend the lower operating temperature limit to -65°C, providing enhanced cold-temperature performance compared to the original -55°C specification.

Viewing Angle Consideration: Substitute parts feature an 18° viewing angle compared to the SE5450-013 20° specification. This represents a 2° reduction in beam divergence, resulting in more focused optical output. Circuit designs dependent on the original 20° beam pattern require optical system evaluation.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP132, and OP133 be used interchangeably with SE5450-013?

A: OP130 provides direct functional substitution with identical radiant intensity specification. OP132 and OP133 are mechanically and electrically compatible but deliver higher optical output (4mW/cm² and 5mW/cm² respectively). Selection depends on application optical requirements and circuit design margins.

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

A: Radiant intensity (Ie) measures optical power per unit solid angle. SE5450-013 specifies 1mW/cm² minimum. OP130 matches this specification. OP132 and OP133 guarantee higher minimum values (4mW/cm² and 5mW/cm² respectively), providing greater optical output at identical 100mA forward current. Applications with optical receiver sensitivity margins can accommodate higher intensity parts.

Q: How does the 18° viewing angle of substitute parts compare to the 20° specification of SE5450-013?

A: Viewing angle defines the half-angle at which radiant intensity drops to 50% of peak value. The 18° specification of substitute parts indicates more focused beam concentration compared to the 20° original specification. Optical system designs relying on the broader 20° beam pattern require evaluation of substitute part compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. SE5450-013 carries RoHS Compliant certification. All substitute parts (OP130, OP132, OP133) carry ROHS3 Compliant certification, confirming compliance with current RoHS directives.

Q: What is the package difference between SE5450-013 and substitute parts?

A: SE5450-013 uses TO-46-2 Metal Can package. Substitute parts use TO-46-2 Lens Top Metal Can package. Both are TO-46-2 form factor with through-hole mounting. The lens top variant on substitute parts may affect optical beam characteristics and should be evaluated in optical system context.

Q: Do substitute parts support the full -55°C to 125°C operating range of SE5450-013?

A: Substitute parts support -65°C to 125°C operating range, extending the lower temperature limit by 10°C. This provides enhanced cold-temperature performance. Applications operating within the original -55°C to 125°C range are fully supported by all substitute parts.

Q: What is the forward voltage difference, and does it affect circuit design?

A: SE5450-013 specifies 1.7V typical forward voltage. Substitute parts specify 1.75V typical forward voltage, representing a 0.05V increase. This variation is within standard component tolerance ranges and typically does not require circuit redesign for current-limited applications. Series resistor values may require minor adjustment for voltage-limited designs.

Q: Are substitute parts available in the same packaging format as SE5450-013?

A: All substitute parts are supplied in bulk packaging. SE5450-013 was supplied in unspecified packaging format. Substitute parts maintain identical TO-46-2 through-hole form factor suitable for automated and manual assembly processes.
