OPF1412 Equivalent & Substitute Parts

Part Overview

The OPF1412 is a fiber optic transmitter operating at 840nm wavelength with an ST connector interface. Manufactured by TT Electronics/Optek Technology, this component is classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for system redesign, maintenance, and new production implementations. The primary substitute maintains core electrical and mechanical compatibility while offering active product status and improved supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPF1412 is determined by the following critical parameters:

• Connector Type: ST interface required for mechanical compatibility
• Maximum Forward Current: 100 mA operational threshold
• Reverse Voltage Rating: 1.8 V maximum specification
• Capacitance: 55 pF characteristic
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The HFBR-1412Z qualifies as a substitute based on matching connector type (ST), identical maximum forward current (100 mA), identical reverse voltage rating (1.8 V), and identical capacitance (55 pF). Both components maintain ROHS3 compliance and REACH unaffected status. The wavelength difference (840nm vs. 820nm) and forward voltage difference (2.09V vs. 1.7V) represent the primary electrical distinctions between these components.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-1412Z is the manufacturer-recommended substitute for the obsolete OPF1412. Both components maintain identical compliance certifications (ROHS3 compliant, REACH unaffected) and share critical electrical parameters including maximum forward current, reverse voltage rating, and capacitance specifications. The HFBR-1412Z offers active product status with established supply chain availability (1900 units in stock versus 677 units for the OPF1412). The component is supplied in tube packaging format.

Selection of the HFBR-1412Z is appropriate for applications where the 820nm wavelength and 1.7V forward voltage characteristics are compatible with system requirements. The identical ST connector interface ensures mechanical compatibility without redesign of optical coupling interfaces.

Frequently Asked Questions (FAQ)

Q: Can the HFBR-1412Z directly replace the OPF1412 in existing designs?

A: The HFBR-1412Z matches the OPF1412 in connector type (ST), maximum forward current (100 mA), reverse voltage rating (1.8 V), and capacitance (55 pF). The primary differences are wavelength (820nm vs. 840nm) and forward voltage (1.7V vs. 2.09V). Direct substitution is valid only if the receiving system is compatible with these electrical and optical characteristics.

Q: What is the significance of the wavelength difference between 840nm and 820nm?

A: Wavelength determines the optical frequency and is application-specific. Systems designed for 840nm operation may not function identically with 820nm components. Compatibility depends on the receiver specifications and system design parameters.

Q: Are both components compliant with current regulatory standards?

A: Both the OPF1412 and HFBR-1412Z are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in forward voltage between these components?

A: The OPF1412 operates at 2.09V typical forward voltage, while the HFBR-1412Z operates at 1.7V typical forward voltage. This difference affects circuit design, particularly in current-limiting resistor calculations and power supply requirements.

Q: Is the HFBR-1412Z available in different packaging formats?

A: The HFBR-1412Z is supplied in tube packaging. The OPF1412 packaging format is not specified in the available data.
