OPV320 Equivalent & Substitute Parts

Part Overview

The OPV320 is a laser diode operating at 850nm wavelength with 1.5mW output power in a pill package format. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement. The OPV322 serves as the manufacturer-recommended equivalent, offering the same core optical specifications while maintaining compatibility with the pill package form factor.

Key Parameters

Substitute Part Grouping Explanation

The OPV322 qualifies as a direct substitute for the OPV320 based on the following critical parameters:

• Wavelength Match: Both components operate at 850nm, ensuring optical compatibility in infrared applications
• Power Output Match: Both deliver 1.5mW, maintaining equivalent optical performance
• Package Compatibility: Both use pill package format, allowing mechanical interchangeability
• Moisture Sensitivity: Both rated MSL 1 (Unlimited), indicating identical handling requirements
• Regulatory Compliance: Both maintain REACH Unaffected status and EAR99 ECCN classification

The primary difference lies in operational current requirements: the OPV322 operates at 7mA with 2.2V input, compared to the OPV320's 20mA specification. This represents improved efficiency in the substitute part while maintaining identical optical output.

Parameter Comparison

Engineering Selection Recommendations

The OPV322 is the manufacturer-designated substitute for the obsolete OPV320. Both components maintain identical wavelength and power specifications, ensuring functional equivalence in 850nm infrared applications. The OPV322 carries Active product status with full availability, addressing the supply discontinuation of the OPV320. Both parts maintain REACH Unaffected compliance and EAR99 export classification, supporting equivalent regulatory requirements. The OPV322's reduced current consumption (7mA versus 20mA) represents a design improvement without compromising optical performance.

Frequently Asked Questions (FAQ)

Q: Can the OPV322 directly replace the OPV320 in existing designs?

A: Yes. Both components share identical wavelength (850nm) and power output (1.5mW) specifications with compatible pill package form factors. The OPV322 operates at lower current (7mA) and specified voltage (2.2V), which may require circuit adjustment but maintains optical equivalence.

Q: What is the primary reason for substitution?

A: The OPV320 is classified as obsolete. The OPV322 is the manufacturer-recommended active equivalent, ensuring continued component availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Both components use pill package format. The OPV320 is specified as loose packaging while the OPV322 is supplied in bulk packaging. This affects procurement and handling but does not impact component functionality.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both maintain REACH Unaffected status and EAR99 ECCN classification, supporting identical regulatory compliance profiles.

Q: What is the significance of the current rating difference?

A: The OPV322 operates at 7mA compared to the OPV320's 20mA specification. This reflects improved efficiency in the substitute part. Circuit designs must accommodate the specified 2.2V input voltage for the OPV322.
