HCNW136 Equivalent & Substitute Parts

Part Overview

The HCNW136 is an optoisolator transistor manufactured by Broadcom Limited, designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This through-hole 8-DIP component integrates a single isolation channel with transistor output and base connection, operating across the industrial temperature range of -55°C to 85°C. The part is currently in active production status with substantial inventory availability (9318 pcs in stock). Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and packaging format options while maintaining functional compatibility within specified electrical parameters.

Substitute Part Grouping Explanation

Substitute parts for the HCNW136 are qualified based on the following critical parameters that define functional interchangeability:

Isolation Voltage: Minimum 5000Vrms (equal or greater)
Package / Case: 8-DIP (0.400", 10.16mm) form factor
Mounting Type: Through Hole
Output Type: Transistor with Base
Number of Channels: 1
Input Type: DC
Current - Output / Channel: 8mA capability

Engineering Selection Recommendations

HCNW136-000E is the preferred direct substitute when supply of the base HCNW136 is constrained. This part maintains identical electrical specifications and packaging while offering improved RoHS3 compliance status and higher inventory availability (17855 pcs). Selection of HCNW136-000E introduces no design modifications and is suitable for drop-in replacement in existing applications.

6N136-X006 is a qualified functional substitute for applications where enhanced performance characteristics are acceptable. This Vishay part provides superior isolation voltage margin (5300Vrms vs 5000Vrms), higher current transfer ratio (19% vs 15%), and faster switching response (200ns vs 1µs). However, the reduced maximum output voltage (15V vs 20V) requires circuit-level verification for applications operating near the 20V output limit. The extended operating temperature range (-55°C to 100°C) provides additional thermal margin. Both substitute parts carry ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can HCNW136-000E be used as a direct replacement for HCNW136?

A: Yes. HCNW136-000E is electrically and mechanically identical to HCNW136, with the same isolation voltage (5000Vrms), current transfer ratio (15% @ 16mA), output voltage rating (20V), and 8-DIP through-hole package. The primary difference is packaging format (tube vs unspecified) and improved RoHS3 compliance status.

Q: What are the key differences between HCNW136 and 6N136-X006?

A: The 6N136-X006 offers higher isolation voltage (5300Vrms), improved current transfer ratio (19% @ 16mA), and faster switching times (200ns vs 1µs). However, it has a lower maximum output voltage (15V vs 20V) and extended operating temperature range (-55°C to 100°C vs -55°C to 85°C). Both use identical 8-DIP through-hole packaging.

Q: Is the 6N136-X006 suitable for all HCNW136 applications?

A: The 6N136-X006 is suitable for most applications. Circuit verification is required only for designs that depend on the full 20V output voltage capability, as this part is rated to 15V maximum output. All other electrical parameters are compatible or superior.

Q: What is the packaging difference between these parts?

A: All three parts (HCNW136, HCNW136-000E, and 6N136-X006) use identical 8-DIP (0.400", 10.16mm) through-hole package format. The primary packaging difference is the supplier delivery format (tube vs bulk), which does not affect circuit performance or PCB mounting.

Q: Are there RoHS compliance considerations for part selection?

A: The HCNW136 is RoHS non-compliant. Both substitute parts (HCNW136-000E and 6N136-X006) are ROHS3 compliant. For applications subject to RoHS requirements, either substitute part is recommended.
