PS8602L1-A Equivalent & Substitute Parts

Part Overview

The PS8602L1-A is an optoisolator with transistor output, featuring 5000Vrms isolation voltage for single-channel DC input applications. Manufactured by CEL in a through-hole 8-DIP package, this component is classified as obsolete, necessitating identification of active substitute parts for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution for PS8602L1-A is based on the following critical parameters: 5000Vrms isolation voltage, single-channel configuration, DC input type, transistor output topology, 8-DIP through-hole package form factor, 8mA output current capacity, and compatible operating temperature range. The active substitute parts are grouped into two categories:

Group 1: Transistor Output Type (Direct Functional Equivalent)

• HCNW4504 and HCNW4504-000E (Broadcom Limited) maintain the same transistor output topology as the PS8602L1-A, with identical isolation voltage, channel count, input/output specifications, and package dimensions.

Group 2: Transistor with Base Output Type (Enhanced Functionality)

• 6N135M and 6N136M (onsemi) feature transistor with base output, providing additional circuit design flexibility while maintaining 5000Vrms isolation, single-channel operation, DC input, 8mA output current, and 8-DIP package compatibility. These parts differ in package body dimensions (7.62mm vs 10.16mm) and operating temperature range (-40°C ~ 100°C minimum).

Parameter Comparison

Engineering Selection Recommendations

HCNW4504 and HCNW4504-000E are the primary active substitutes for PS8602L1-A due to identical output transistor topology and package body dimensions (0.400", 10.16mm). Both parts maintain the same isolation voltage, channel count, and output current specifications. HCNW4504-000E provides RoHS3 compliance and maintains the full -55°C to 100°C operating temperature range of the original part, making it suitable for applications requiring environmental compliance and extended temperature operation. HCNW4504 covers the same temperature range but is not RoHS-compliant.

6N135M and 6N136M offer viable substitution with the added feature of base output on the transistor, allowing enhanced circuit control. These active onsemi parts maintain 5000Vrms isolation and 8mA output current but operate within a narrower temperature range (-40°C minimum). The smaller package body dimension (0.300", 7.62mm) may require board layout modification. 6N136M provides higher minimum current transfer ratio (19% vs 7%) compared to 6N135M, offering more consistent performance at -16mA test conditions.

All substitute parts maintain REACH compliance designation (REACH Unaffected or Affected) and share identical HTSUS and ECCN classifications as the PS8602L1-A.

Frequently Asked Questions (FAQ)

Q: Can HCNW4504 directly replace PS8602L1-A in existing PCB designs? A: Yes. Both parts share identical package body dimensions (0.400", 10.16mm), 8-DIP through-hole configuration, and output transistor topology. No board redesign is required.

Q: What is the difference between the onsemi 6N135M and 6N136M? A: Both parts feature transistor with base output and maintain 5000Vrms isolation. The 6N136M specifies a higher minimum current transfer ratio (19% @ 16mA) compared to 6N135M (7% @ 16mA), providing tighter performance characteristics. Both operate within -40°C to 100°C range.

Q: Why do onsemi parts (6N135M, 6N136M) have smaller package dimensions? A: The onsemi 6N135M and 6N136M use 8-DIP packages with 0.300" (7.62mm) body width compared to 0.400" (10.16mm) for the PS8602L1-A and Broadcom HCNW4504 variants. This requires PCB footprint verification before substitution in existing designs.

Q: Are there compliance differences between HCNW4504 and HCNW4504-000E? A: HCNW4504-000E maintains RoHS3 compliance and operates at -55°C to 85°C. HCNW4504 is RoHS non-compliant but supports the full -55°C to 100°C operating range. Select based on environmental compliance requirements and temperature operation of your application.

Q: Does the transistor with base output affect circuit compatibility? A: The base output on 6N135M and 6N136M provides additional design flexibility for output circuit control but does not prevent substitution into standard transistor output applications. Base terminal can be left unconnected for transparent operation equivalent to standard transistor output.

Q: What inventory availability should I consider? A: HCNW4504-000E (1221 pcs), HCNW4504 (2023 pcs), 6N136M (88925 pcs), and 6N135M (3684 pcs) are in stock. 6N136M offers the highest inventory quantity.
