Substitute Part Grouping Explanation

Substitute parts for the HCPL0700R2 are identified from the HCPL-070 series manufactured by Broadcom Limited. Substitution is based on the following criteria:

Matching Parameters:

Single-channel optoisolator configuration
Darlington output with base connection
8-SOIC surface mount package (0.154", 3.90mm Width)
DC input type
60mA output current per channel
1.25V typical forward voltage
MSL 1 (Unlimited) moisture sensitivity level
REACH Unaffected and EAR99 ECCN classification

Allowable Variations:

Voltage isolation rating: HCPL-070 series provides 3750Vrms, which exceeds the 2500Vrms requirement
Current transfer ratio: HCPL-070 series specifications differ from HCPL0700R2 due to different test conditions (500µA vs 1.6mA)
Turn-on/turn-off timing: HCPL-070 series exhibits different switching characteristics
Maximum output voltage: HCPL-070 series supports 18V versus 7V for HCPL0700R2
Operating temperature range: HCPL-070 series operates 0°C ~ 70°C versus -40°C ~ 85°C for HCPL0700R2

Engineering Selection Recommendations

HCPL-070A-500E is the primary substitute option. This part maintains ROHS3 compliance matching the HCPL0700R2, offers the highest inventory availability at 6420 units, and is supplied in Cut Tape (CT) & Digi-Reel® packaging suitable for automated assembly processes.

HCPL-070A-000E is an alternative substitute with ROHS3 compliance and Tube packaging. Inventory is lower at 1377 units.

HCPL-070A is not recommended for new designs due to RoHS non-compliance, despite adequate inventory levels of 2340 units.

All three Broadcom substitutes exceed the isolation voltage requirement and support higher maximum output voltage, making them suitable for applications where the HCPL0700R2 is specified. The narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can HCPL-070A series parts directly replace HCPL0700R2 in existing designs?

A: Mechanical and electrical compatibility exists for the 8-SOIC package footprint and pin configuration. However, the operating temperature range differs. HCPL-070A series operates 0°C ~ 70°C while HCPL0700R2 operates -40°C ~ 85°C. Applications requiring extended temperature operation must evaluate this limitation.

Q: What is the significance of the higher isolation voltage in HCPL-070A series?

A: The 3750Vrms isolation rating in HCPL-070A series exceeds the 2500Vrms requirement of HCPL0700R2. This provides additional safety margin in high-voltage isolation applications but does not affect functional compatibility for circuits designed around the lower rating.

Q: How do current transfer ratios differ between these parts?

A: HCPL0700R2 specifies current transfer ratio at 1.6mA input current, while HCPL-070A series specifies at 500µA. These different test conditions result in different reported ratios. Direct comparison requires evaluation at identical input current levels for the specific application.

Q: Are there packaging differences between substitute options?

A: HCPL-070A-500E is supplied in Cut Tape (CT) & Digi-Reel® format optimized for automated pick-and-place assembly. HCPL-070A-000E uses Tube packaging. HCPL0700R2 is supplied in Tape & Reel (TR). Packaging selection depends on assembly process requirements.

Q: Which substitute is recommended for RoHS-compliant applications?

A: Both HCPL-070A-500E and HCPL-070A-000E carry ROHS3 compliance certification. HCPL-070A is RoHS non-compliant and should not be used in applications requiring RoHS compliance.
