Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-7800#300 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Amplifier Type: Isolation
• Number of Circuits: 1
• -3dB Bandwidth: 100 kHz
• Current - Input Bias: 500 nA
• Voltage - Input Offset: 300 µV
• Current - Supply: 10.9 mA
• Current - Output / Channel: 16 mA
• Voltage - Supply Span: 4.5 V to 5.5 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Compatibility Requirements:

• Package / Case: 8-SMD, Gull Wing
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

The HCPL-7800-300E meets all electrical and mechanical equivalence criteria and is therefore classified as a direct substitute for the HCPL-7800#300.

Parameter Comparison

Engineering Selection Recommendations

HCPL-7800#300 Selection Criteria:

• Use when RoHS non-compliant components are acceptable for the application
• Current inventory of 980 units supports immediate procurement
• All electrical and mechanical specifications are identical to the substitute part

HCPL-7800-300E Selection Criteria:

• Use when ROHS3 compliance is required by design specifications or regulatory requirements
• Higher inventory availability (2300 units) supports larger volume orders and supply chain continuity
• Identical electrical performance and mechanical compatibility ensure direct substitution without circuit redesign
• Both REACH Unaffected status and EAR99 ECCN classification are maintained

Both parts are active products from Broadcom Limited with identical functional specifications. Selection between them is determined by compliance requirements and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can HCPL-7800-300E be used as a direct replacement for HCPL-7800#300 in existing designs?

A: Yes. The HCPL-7800-300E is electrically and mechanically equivalent to the HCPL-7800#300. All electrical parameters, operating temperature range, supply voltage specifications, and package configuration are identical. No circuit modifications are required for substitution.

Q: What is the difference between HCPL-7800#300 and HCPL-7800-300E?

A: The primary difference is RoHS compliance status. The HCPL-7800#300 is RoHS non-compliant, while the HCPL-7800-300E is ROHS3 compliant. All other specifications, including electrical performance, operating characteristics, and mechanical packaging, are identical.

Q: Are the packages identical between these two parts?

A: Yes. Both parts use 8-SMD Gull Wing surface mount packaging with identical pin configuration, footprint, and mounting requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the significance of the MSL rating for these components?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and storage procedures for both the HCPL-7800#300 and HCPL-7800-300E.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring ROHS3 compliance, the HCPL-7800-300E is the appropriate choice. For applications without RoHS compliance mandates, either part is functionally suitable. The HCPL-7800-300E offers higher inventory availability for supply chain planning.

Q: Are there any temperature or supply voltage differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and require supply voltage between 4.5 V and 5.5 V. Operating characteristics and performance specifications are fully equivalent.
