Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPF352A is determined by the following critical parameters:

• Wavelength: 850nm (required match)
• Connector Type: ST (required match)
• Current - DC Forward (If) Maximum: 100 mA (required match)
• Voltage - DC Reverse (Vr) Maximum: 1V (required match)
• RoHS Compliance: ROHS3 Compliant (required match)

The OPF372A qualifies as a manufacturer-recommended substitute. While spectral bandwidth differs (35nm versus 50nm) and forward voltage is higher (2V versus 1.8V), these parameters remain within acceptable substitution criteria for this product category. The OPF372A maintains identical wavelength, connector type, maximum forward current, reverse voltage rating, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The OPF372A is the manufacturer-recommended substitute for the obsolete OPF352A. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The OPF372A is currently in active production status, providing supply chain continuity and availability advantages over the obsolete OPF352A.

The primary electrical difference is the forward voltage specification: OPF372A operates at 2V typical versus 1.8V for the OPF352A. This 0.2V increase must be evaluated within the context of the application circuit design. The narrower spectral bandwidth of the OPF372A (35nm versus 50nm) represents improved wavelength definition, which may enhance system performance in wavelength-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the OPF372A directly replace the OPF352A in existing designs?

A: The OPF372A is the manufacturer-recommended substitute and shares critical electrical parameters including wavelength, connector type, maximum forward current, and reverse voltage rating. Circuit design must accommodate the 0.2V higher forward voltage specification of the OPF372A.

Q: What is the significance of the spectral bandwidth difference?

A: The OPF352A has 50nm spectral bandwidth while the OPF372A has 35nm. The narrower bandwidth of the OPF372A indicates more concentrated wavelength output, which may improve performance in systems requiring precise wavelength definition.

Q: Are both components RoHS compliant?

A: Yes, both the OPF352A and OPF372A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the OPF352A listed as obsolete?

A: The OPF352A is no longer in active production. The OPF372A represents the current active alternative from the manufacturer for this application category.

Q: Does the connector type remain the same?

A: Yes, both components use ST connectors, ensuring mechanical compatibility in existing fiber optic systems.
