Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE5455-001 are qualified based on the following critical parameters that determine functional equivalence:

Core Electrical Parameters:

• Wavelength: 935nm (exact match required)
• Maximum Forward Current: 100mA (exact match required)
• Forward Voltage: Tolerance within typical operating range
• Radiant Intensity: Measured at specified current levels

Mechanical & Environmental Parameters:

• Package Type: TO-46-2 metal can configuration
• Mounting Type: Through-hole compatibility
• Operating Temperature Range: Minimum coverage of -55°C to 125°C
• Viewing Angle: Optical field of view characteristics

Compliance & Quality Parameters:

• RoHS Compliance Status
• Moisture Sensitivity Level (MSL)
• Product Status: Active or equivalent lifecycle stage

The substitute parts OP130, OP131, and OP133 (all manufactured by TT Electronics/Optek Technology) meet the core electrical and mechanical requirements for substitution. These parts maintain the 935nm wavelength, 100mA maximum forward current, TO-46-2 package configuration, and through-hole mounting compatibility. All substitute parts carry active product status and ROHS3 compliance certification.

Engineering Selection Recommendations

OP130 Selection Criteria: The OP130 is suitable for applications where radiant intensity of 1mW/cm² at 100mA is acceptable. This part carries active product status and ROHS3 compliance, providing long-term supply chain stability. The forward voltage of 1.75V represents a 0.05V increase from the SE5455-001, which is within typical circuit tolerance margins for infrared emitter applications. The extended operating temperature range (-65°C to 125°C) provides additional environmental coverage.

OP131 Selection Criteria: The OP131 offers intermediate radiant intensity at 3mW/cm² at 100mA, suitable for applications requiring moderate optical output. Active product status and ROHS3 compliance ensure continued availability. This part is appropriate for designs where the SE5455-001's unspecified radiant intensity requires a defined performance level in the mid-range.

OP133 Selection Criteria: The OP133 provides the highest radiant intensity at 5mW/cm² at 100mA among the substitute options. This part is recommended for applications requiring maximum optical output within the 100mA current constraint. Active product status and ROHS3 compliance certification support production continuity. The 3400-piece inventory level indicates strong supply availability.

General Substitution Considerations: All substitute parts maintain the critical 935nm wavelength and 100mA maximum forward current specifications. The viewing angle difference (20° for SE5455-001 versus 18° for substitutes) represents a minor optical field reduction. The forward voltage increase of 0.05V across all substitutes is negligible for most circuit designs. All substitute parts carry superior compliance certifications (ROHS3) and active product status, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP131, and OP133 be used interchangeably with SE5455-001?

A: These parts share identical wavelength (935nm) and maximum forward current (100mA) specifications, making them functionally equivalent for core infrared emission applications. The primary differences are radiant intensity levels and viewing angle. Selection depends on the specific radiant intensity requirement of the application. All parts maintain TO-46-2 through-hole package compatibility.

Q: What is the significance of the radiant intensity differences between OP130, OP131, and OP133?

A: Radiant intensity (measured in mW/cm²) determines the optical power output at a specified distance. OP130 provides 1mW/cm², OP131 provides 3mW/cm², and OP133 provides 5mW/cm² at 100mA. Applications requiring higher optical output should select OP133, while lower-intensity applications may use OP130. The SE5455-001 does not specify radiant intensity, requiring application-specific evaluation.

Q: How does the viewing angle difference affect substitution?

A: The SE5455-001 has a 20° viewing angle, while all substitute parts have 18° viewing angles. This represents a 2° reduction in optical field of view. For applications where the optical beam pattern is critical, this difference must be evaluated against specific design requirements. In most general-purpose infrared applications, this difference is negligible.

Q: Are there compliance differences between SE5455-001 and the substitute parts?

A: The SE5455-001 carries RoHS Compliant status, while all substitute parts carry ROHS3 Compliant status. ROHS3 represents an updated compliance standard. All parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating. The substitute parts include REACH Unaffected status, providing additional regulatory documentation.

Q: What is the impact of the forward voltage difference?

A: The SE5455-001 specifies 1.7V typical forward voltage, while all substitute parts specify 1.75V. This 0.05V difference is within normal circuit tolerance for infrared emitter applications and should not require circuit redesign in most cases. Circuit designers should verify that current-limiting resistor values accommodate this minor voltage variation.

Q: Why is product status important for this substitution?

A: The SE5455-001 is obsolete, meaning Honeywell no longer manufactures or supports this part. All substitute parts carry active product status, ensuring continued manufacturing, availability, and technical support. Active status provides long-term supply chain security for production applications.

Q: Are the substitute parts available in the same packaging options?

A: The SE5455-001 is specified with standard TO-46-2 metal can packaging. OP130 and OP133 are available in bulk packaging, while OP131 packaging is not specified in the provided data. All parts use TO-46-2 Lens Top Metal Can package configuration, maintaining through-hole mounting compatibility.

Q: Can I use these parts in new designs, or only as replacements?

A: All substitute parts carry active product status and current compliance certifications (ROHS3), making them suitable for both new designs and replacement applications. The active status ensures long-term availability and technical support for ongoing production.
