Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE5455-004 is determined by the following critical parameters:

Primary Matching 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)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Typ): Tolerance range 1.7V to 1.75V
• Viewing Angle: Range 18° to 20°
• Operating Temperature Range: Minimum -55°C, Maximum 125°C or broader

All four substitute parts (OP130, OP131, OP132, OP133) manufactured by TT Electronics/Optek Technology meet the primary matching criteria. Variations in radiant intensity (Ie), forward voltage, and viewing angle represent performance differences within acceptable substitution parameters for 935nm infrared emitter applications.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status:

All substitute parts (OP130, OP131, OP132, OP133) are ROHS3 compliant and carry REACH Unaffected status, providing enhanced regulatory alignment compared to the obsolete SE5455-004. All parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring consistent export and tariff treatment.

Product Availability:

The SE5455-004 is obsolete with limited inventory (883 pcs). All substitute parts are active products with substantially higher inventory levels: OP130 (1738 pcs), OP131 (1900 pcs), OP132 (2049 pcs), and OP133 (3400 pcs). This availability differential supports long-term supply chain continuity.

Electrical Compatibility:

Forward voltage variation (1.7V to 1.75V) represents a 2.9% increase across substitute options. Operating temperature range expansion to -65°C minimum provides broader environmental coverage. All parts maintain 100mA maximum forward current and 935nm wavelength specifications.

Optical Performance Differentiation:

Radiant intensity varies across substitute parts: OP130 (1mW/cm²), OP131 (3mW/cm²), OP132 (4mW/cm²), and OP133 (5mW/cm²). Viewing angle narrows from 20° (SE5455-004) to 18° (all substitutes). Selection should align with application-specific optical output requirements.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP131, OP132, and OP133 be used interchangeably with SE5455-004?

A: These parts share identical wavelength (935nm), maximum forward current (100mA), package type (TO-46-2 Metal Can), and mounting configuration (through-hole). Substitution is electrically and mechanically compatible. Differences in radiant intensity and viewing angle must be evaluated against specific application requirements.

Q: What is the significance of the radiant intensity differences among the substitute parts?

A: Radiant intensity (Ie) quantifies optical power output per unit solid angle. OP130 provides 1mW/cm², OP131 provides 3mW/cm², OP132 provides 4mW/cm², and OP133 provides 5mW/cm² at 100mA. Applications requiring higher optical output should select OP132 or OP133. Applications with lower optical requirements may use OP130 or OP131.

Q: How does the viewing angle difference affect substitution?

A: SE5455-004 specifies a 20° viewing angle, while all substitute parts specify 18°. This 2° reduction narrows the angular distribution of infrared emission. Applications requiring wider angular coverage should account for this specification change during optical system design validation.

Q: Are there compliance or certification differences between the main part and substitutes?

A: SE5455-004 is RoHS Compliant. All substitute parts are ROHS3 Compliant with REACH Unaffected status, representing enhanced regulatory compliance. Both compliance levels are acceptable for most applications; ROHS3 represents a more current standard.

Q: What is the forward voltage tolerance between SE5455-004 and the substitute parts?

A: SE5455-004 specifies 1.7V typical forward voltage. All substitute parts specify 1.75V typical forward voltage, representing a 0.05V (50mV) increase. This variation is within typical circuit design tolerances for infrared emitter applications and does not require circuit redesign.

Q: Why is the operating temperature range broader for substitute parts?

A: SE5455-004 specifies -55°C to 125°C. All substitute parts specify -65°C to 125°C, extending the minimum operating temperature by 10°C. This expanded range provides additional environmental flexibility for applications operating in lower temperature conditions.

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

A: Selection depends on optical output requirements. OP133 (5mW/cm²) provides maximum radiant intensity with highest inventory availability (3400 pcs). OP132 (4mW/cm²) offers balanced performance. OP131 (3mW/cm²) and OP130 (1mW/cm²) serve lower optical output applications. All are active products with long-term availability.

Q: Is the TO-46-2 Lens Top Metal Can package functionally equivalent to the TO-46-2 Metal Can package?

A: Both packages are TO-46-2 form factors with through-hole mounting compatibility. The "Lens Top" designation indicates integrated optical focusing. Mechanical fit and electrical connectivity are equivalent. Optical performance characteristics differ due to lens integration in substitute parts.
