Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-3700#300 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Output configuration: Single channel Darlington output
• Maximum output voltage: 20V
• Output current per channel: 30mA
• Switching timing: 4µs turn-on, 10µs turn-off
• Input capability: AC and DC compatible
• Package type: 8-DIP Gull Wing surface mount
• Temperature range: -40°C to 85°C
• Moisture sensitivity: MSL 1

The HCPL-3700-300E meets all electrical and mechanical parameters required for direct substitution. Both parts share identical base product designation (HCPL-3700) and are manufactured by Broadcom Limited.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3700-300E serves as a direct functional equivalent to the HCPL-3700#300 with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and supply availability:

The HCPL-3700#300 is RoHS non-compliant and suitable for applications without RoHS restrictions. The HCPL-3700-300E is ROHS3 compliant and required for applications subject to RoHS directives or customer specifications mandating RoHS compliance. Both parts maintain REACH Unaffected status and identical MSL ratings. The HCPL-3700-300E offers higher inventory availability at 2400 units compared to 656 units for the HCPL-3700#300.

Frequently Asked Questions (FAQ)

Q: Are HCPL-3700#300 and HCPL-3700-300E electrically interchangeable?

A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical specifications including 3750Vrms isolation, single-channel Darlington output, 20V maximum output voltage, 30mA output current, and switching timing characteristics.

Q: What is the primary difference between these two parts?

A: The HCPL-3700-300E is ROHS3 compliant, while the HCPL-3700#300 is RoHS non-compliant. All other electrical and mechanical parameters are identical.

Q: Can I use HCPL-3700-300E as a replacement for HCPL-3700#300 in existing designs?

A: Yes. The HCPL-3700-300E is a direct substitute with no design modifications required. The identical package type (8-DIP Gull Wing), pinout, and electrical performance ensure drop-in compatibility.

Q: Are there any packaging or handling differences?

A: Both parts share identical moisture sensitivity level (MSL 1 - Unlimited) and surface mount packaging specifications. No differences in storage, handling, or assembly requirements exist.

Q: Which part should I select for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS compliance, specify HCPL-3700-300E. For applications without RoHS restrictions, either part is acceptable based on availability and cost considerations.
