Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OP200 are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 880nm (primary specification)
• Package / Case: 0805 (2012 Metric) surface mount
• Current - DC Forward (If) (Max): 50mA
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Considerations:

• Voltage - Forward (Vf) (Typ): Tolerance within circuit design margins
• Operating Temperature Range: Must encompass application requirements
• Radiant Intensity (Ie) Min @ If: Application-dependent performance metric

The substitute parts identified maintain the same package form factor, maximum forward current rating, and wavelength specification as the OP200, ensuring direct replacement capability in existing PCB layouts and circuit designs.

Engineering Selection Recommendations

XZTHI54W (SunLED) - Primary Substitute

The XZTHI54W maintains exact wavelength specification (880nm) and package compatibility with the OP200. This part is classified as active product status, ensuring long-term availability and supply chain continuity. The XZTHI54W is ROHS3 compliant and operates across an extended temperature range (-40°C ~ 85°C), providing broader environmental tolerance than the original OP200. Forward voltage is reduced to 1.3V, which may reduce power dissipation in circuit designs. Moisture sensitivity level is rated at MSL 3 (168 Hours), requiring standard moisture control during storage and handling.

XZTNI54W (SunLED) - Alternative Substitute

The XZTNI54W provides an alternative for applications where 940nm wavelength operation is acceptable. This part shares identical package form factor, maximum forward current rating, and surface mount characteristics with the OP200. The XZTNI54W is active product status with ROHS3 compliance and extended operating temperature range (-40°C ~ 85°C). Forward voltage is further reduced to 1.2V. Wavelength difference (940nm versus 880nm) requires application-level assessment for spectral compatibility with optical sensors and detection circuits.

Frequently Asked Questions (FAQ)

Q: Can the XZTHI54W directly replace the OP200 in existing designs?

A: The XZTHI54W maintains identical wavelength (880nm), package form factor (0805), and maximum forward current (50mA) specifications. Direct PCB replacement is feasible. Forward voltage reduction from 1.5V to 1.3V may require circuit verification to confirm current-limiting resistor adequacy.

Q: What is the difference between XZTHI54W and XZTNI54W?

A: The primary difference is wavelength specification. XZTHI54W operates at 880nm (matching the OP200), while XZTNI54W operates at 940nm. Both share identical package, current rating, and mounting characteristics. Wavelength selection depends on optical sensor spectral response requirements.

Q: Are there moisture handling differences between the OP200 and substitute parts?

A: The OP200 is rated MSL 1 (Unlimited), while both SunLED substitutes are rated MSL 3 (168 Hours). MSL 3 classification requires moisture control during storage and handling. Standard moisture barrier packaging and bake-out procedures apply before reflow soldering.

Q: Do the substitute parts support the same operating temperature range?

A: The OP200 operates from -25°C to 85°C. Both XZTHI54W and XZTNI54W extend the lower temperature limit to -40°C, providing broader environmental tolerance. Upper temperature limit remains 85°C for all three parts.

Q: What is the viewing angle difference between the OP200 and substitutes?

A: The OP200 specifies 150° viewing angle, while both SunLED substitutes specify 120° viewing angle. This represents a narrower beam concentration in the substitute parts. Application-level assessment is required if beam divergence is a critical optical parameter.
