HCPL0700R1 Equivalent & Substitute Parts

Part Overview

The HCPL0700R1 is a single-channel optoisolator with Darlington output and base connection, manufactured by onsemi. This component provides 2500Vrms isolation and is designed for DC input applications requiring galvanic isolation in 8-SOIC surface mount packaging. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the HCPL0700R1 is determined by the following critical parameters:

Isolation Voltage: Minimum 2500Vrms (higher values acceptable)
Number of Channels: 1 channel required
Output Configuration: Darlington with Base output
Package: 8-SOIC surface mount form factor
Current Transfer Ratio: Minimum 300% @ 1.6mA
Operating Temperature Range: Must support -40°C ~ 85°C
Input Type: DC operation

Substitutes are grouped into two categories:

Direct Parametric Equivalents maintain identical electrical specifications at the specified test conditions (1.6mA input current).

Enhanced Performance Alternatives provide higher isolation voltage (3750Vrms) or improved current transfer ratios at different test conditions (500µA input current), suitable for applications with higher isolation requirements or different input drive levels.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

HCPL0700R2 is the primary direct substitute, maintaining all electrical specifications of the HCPL0700R1 while offering active product status. This part is suitable for applications requiring no design modification.

HCPL-0700-000E provides an alternative with enhanced isolation voltage (3750Vrms) and faster switching times (200ns, 2µs) while maintaining the same current transfer ratio specifications at 1.6mA test current. This part is ROHS3 compliant and active.

For Enhanced Performance Applications:

HCPL-070A series parts (HCPL-070A, HCPL-070A#500, HCPL-070A#560, HCPL-070A-000E, HCPL-070A-500E) offer higher isolation voltage (3750Vrms), higher maximum output voltage (18V), and significantly higher current transfer ratios (600-8000% @ 500µA). These parts require design evaluation due to different input test current conditions and narrower operating temperature range (0°C ~ 70°C). HCPL-070A-500E and HCPL-070A-000E are ROHS3 compliant.

Compliance Considerations:

For applications requiring RoHS3 compliance, select HCPL-0700-000E, HCPL-070A-000E, or HCPL-070A-500E. The HCPL-070A series variants without explicit RoHS3 designation are RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can HCPL0700R2 be used as a direct drop-in replacement for HCPL0700R1?

A: Yes. HCPL0700R2 maintains identical electrical specifications including isolation voltage (2500Vrms), current transfer ratio (300-2600% @ 1.6mA), switching times (1µs, 7µs), and operating temperature range (-40°C ~ 85°C). The primary difference is product status (active vs. obsolete) and packaging format (bulk vs. original).

Q: What is the difference between HCPL-0700-000E and HCPL-070A series?

A: HCPL-0700-000E maintains the same current transfer ratio test conditions as the original part (300-2600% @ 1.6mA) with enhanced isolation (3750Vrms). HCPL-070A series uses a different test current (500µA) resulting in higher current transfer ratios (600-8000%) and higher maximum output voltage (18V). HCPL-070A also has a narrower operating temperature range (0°C ~ 70°C vs. -40°C ~ 85°C).

Q: Are the HCPL-070A variants interchangeable with each other?

A: HCPL-070A, HCPL-070A#500, HCPL-070A#560, HCPL-070A-000E, and HCPL-070A-500E share identical electrical specifications. Differences are in packaging format (Tube, Tape & Reel, Cut Tape) and RoHS compliance status. Selection depends on procurement requirements and compliance mandates.

Q: What packaging options are available?

A: Substitutes are available in Bulk (HCPL0700R2), Tube (HCPL-0700-000E, HCPL-070A, HCPL-070A-000E), Tape & Reel (HCPL-070A#500, HCPL-070A#560), and Cut Tape & Digi-Reel (HCPL-070A-500E). All maintain the 8-SOIC surface mount form factor.

Q: Is the HCPL-070A suitable for applications requiring -40°C operation?

A: No. HCPL-070A series has a minimum operating temperature of 0°C, making it unsuitable for applications requiring -40°C operation. For full -40°C ~ 85°C range support, use HCPL0700R2 or HCPL-0700-000E.

Q: Which substitute offers the best RoHS3 compliance options?

A: HCPL-0700-000E, HCPL-070A-000E, and HCPL-070A-500E are explicitly ROHS3 compliant. HCPL0700R2 and HCPL-070A series without explicit RoHS3 designation should be verified for compliance requirements.
