HCPL0501V Equivalent & Substitute Parts

Part Overview

The HCPL0501V is a single-channel optoisolator with transistor output manufactured by onsemi. This component provides galvanic isolation up to 2500Vrms and is designed for high-speed switching applications requiring DC input control. The part is currently in Last Time Buy status, making identification of equivalent alternatives essential for ongoing design support and procurement planning. Substitute parts must maintain identical electrical performance and mechanical compatibility across isolation voltage, current transfer ratio, switching speed, and package specifications.

Substitute Part Grouping Explanation

Substitution for the HCPL0501V is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 2500Vrms (mandatory match)
Number of Channels: 1 (mandatory match)
Current Transfer Ratio Range: 19% to 50% @ 16mA (mandatory match)
Switching Speed: Turn On 450ns / Turn Off 300ns (mandatory match)
Output Configuration: Transistor with Base (mandatory match)
Output Voltage & Current Ratings: 20V max, 8mA per channel (mandatory match)
Input Diode Characteristics: Vf 1.45V typical, If 25mA max (mandatory match)
Package: 8-SOIC form factor (mandatory match)
Temperature Range: -40°C to 85°C (mandatory match)

Two substitute parts meet these criteria with identical electrical specifications and mechanical compatibility.

Engineering Selection Recommendations

HCPL0501R2V (Fairchild Semiconductor): This substitute provides full parametric equivalence with identical electrical specifications. Product status is Active, ensuring continued availability. ECCN and HTSUS classifications match the main part. Inventory availability is 6150 units. This part is suitable for direct substitution in applications where Fairchild sourcing is acceptable.

HCPL0501 (onsemi): This substitute maintains complete electrical and mechanical compatibility as a parametric equivalent. Manufactured by the same supplier as the main part, it carries Active product status with 2420 units in stock. RoHS3 compliance and MSL rating are identical to the main part. This option provides continuity within the onsemi product line and is recommended for designs requiring single-source qualification.

Both substitutes are qualified for use in applications currently specified for HCPL0501V without circuit modification, provided that procurement and supply chain requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can HCPL0501R2V be used as a direct replacement for HCPL0501V?

A: Yes. HCPL0501R2V meets all electrical and mechanical specifications of HCPL0501V, including isolation voltage, current transfer ratio, switching speed, output ratings, and 8-SOIC package form factor. No circuit changes are required.

Q: What is the difference between HCPL0501V and HCPL0501?

A: Both parts are manufactured by onsemi and share identical electrical specifications and package configuration. The primary difference is product status: HCPL0501V is Last Time Buy, while HCPL0501 is Active. HCPL0501 is the recommended long-term alternative within the onsemi product family.

Q: Are there packaging differences between the substitutes?

A: The main part (HCPL0501V) is supplied in Tube packaging. HCPL0501R2V is supplied in Bulk packaging, and HCPL0501 is supplied in Box packaging. All three use identical 8-SOIC (0.154", 3.90mm Width) component packages suitable for surface mount assembly.

Q: Do all three parts have the same RoHS and MSL ratings?

A: HCPL0501V and HCPL0501 are both ROHS3 Compliant with MSL 1 (Unlimited). HCPL0501R2V compliance information is not specified in available data.

Q: Which substitute should be selected for new designs?

A: HCPL0501 is recommended for new designs as it maintains onsemi sourcing continuity and carries Active product status with full compliance documentation. HCPL0501R2V is suitable where multi-source qualification is required or Fairchild supply chain preference exists.
