Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the HFE4020-313 is based on the following criteria:

Functional Category: Fiber optic transmission components operating in the infrared spectrum

Key Substitution Parameters:

• Fiber optic signal transmission capability
• Operating wavelength compatibility (850nm range)
• Electrical specifications (voltage and current ratings)
• Packaging form factor compatibility
• Environmental compliance (RoHS, MSL ratings)

The OPF345A qualifies as a substitute based on its classification as an active fiber optic transmitter with defined electrical and optical parameters suitable for applications requiring 850nm wavelength transmission.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement:

The OPF345A represents an active substitute for the discontinued HFE4020-313. Selection of this substitute is supported by:

• Product Status Alignment: OPF345A maintains active manufacturing status, ensuring continued availability and supply chain reliability
• Compliance Certification: Both components meet RoHS compliance requirements; OPF345A carries ROHS3 Compliant designation
• Environmental Rating: Identical MSL rating (1 - Unlimited) indicates equivalent moisture handling and storage requirements
• Functional Category: Both components operate within the fiber optic transmission domain with defined electrical parameters

Inventory Consideration: Current stock of HFE4020-313 (1120 Pcs) is available; OPF345A inventory (1150 Pcs) provides alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Why is the HFE4020-313 classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production. This status necessitates identification of active substitute components for system continuity and future procurement.

Q: What are the primary substitution criteria for fiber optic transceiver modules?

A: Substitution is determined by operating wavelength, electrical specifications (forward voltage and current ratings), reverse voltage ratings, packaging compatibility, and environmental compliance certifications (RoHS, MSL).

Q: Is the OPF345A a direct functional equivalent?

A: The OPF345A is classified as a fiber optic transmitter with specified 850nm wavelength operation. Functional equivalence depends on application-specific requirements including wavelength compatibility, electrical parameter matching, and connector type requirements.

Q: What is the significance of MSL rating 1 (Unlimited)?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions without requiring special moisture control measures. Both HFE4020-313 and OPF345A share this rating.

Q: Are there packaging differences between these components?

A: HFE4020-313 packaging is not specified in available data. OPF345A is supplied in Bulk packaging with TO46 form factor. Packaging compatibility must be verified for specific application requirements.

Q: What compliance certifications apply to these components?

A: HFE4020-313 is RoHS Compliant. OPF345A is ROHS3 Compliant and REACH Unaffected. Both meet environmental regulatory requirements for their respective manufacturing periods.
