Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPF1412T is determined by the following critical parameters: wavelength, forward voltage, forward current rating, reverse voltage rating, capacitance, connector type, and compliance certifications. The substitute parts identified maintain compatibility through matching or functionally equivalent electrical and mechanical specifications.

OPF1414T qualifies as a direct substitute based on identical wavelength (840nm), forward voltage (2.09V), forward current (100 mA), reverse voltage (1.8V), capacitance (55 pF), and ST connector type. This part is manufactured by the same supplier (TT Electronics/Optek Technology) and maintains active product status with ROHS3 compliance.

HFBR-1412TZ is identified as a manufacturer-recommended alternative despite operating at a different wavelength (820nm). This Broadcom Limited device maintains the same forward current rating (100 mA), reverse voltage (1.8V), capacitance (55 pF), and ST connector type. The wavelength difference (820nm versus 840nm) represents a functional variation that must be evaluated against system requirements.

Parameter Comparison

Engineering Selection Recommendations

OPF1414T is the primary substitute for OPF1412T applications. Both parts maintain identical electrical specifications across all critical parameters and share the same manufacturer. OPF1414T holds active product status, ensuring continued availability and supply chain stability. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

HFBR-1412TZ serves as an alternative substitute when OPF1414T is unavailable. This Broadcom Limited device maintains the same forward current rating, reverse voltage, capacitance, and ST connector interface. The forward voltage differs at 1.7V compared to 2.09V, and the wavelength operates at 820nm rather than 840nm. HFBR-1412TZ is actively manufactured and fully compliant with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can OPF1414T directly replace OPF1412T without circuit modifications?

A: Yes. OPF1414T maintains identical electrical parameters including wavelength (840nm), forward voltage (2.09V), forward current (100 mA), reverse voltage (1.8V), and capacitance (55 pF). The ST connector type is identical. No circuit modifications are required.

Q: What are the key differences between OPF1412T and HFBR-1412TZ?

A: The primary differences are wavelength (840nm versus 820nm) and forward voltage (2.09V versus 1.7V). Both devices maintain identical forward current (100 mA), reverse voltage (1.8V), capacitance (55 pF), and ST connector type. System optical and electrical design must accommodate these parameter variations.

Q: Why is OPF1412T classified as obsolete?

A: OPF1412T is listed as obsolete by the manufacturer. OPF1414T, manufactured by the same supplier, provides an active-status equivalent with identical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. OPF1414T and HFBR-1412TZ both carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory standards.

Q: What is the significance of the ST connector type?

A: The ST connector type is a mechanical and optical interface standard. All listed parts maintain ST connector compatibility, ensuring physical and optical alignment in existing fiber optic systems.

Q: Does moisture sensitivity affect component handling?

A: All parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.
