Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5962-8978503KPC is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - Isolation: 1500VDC (mandatory match)
• Package / Case: 8-DIP (0.300", 7.62mm) (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Input Type: DC (mandatory match)
• Output Type: Darlington (mandatory match)
• Current Transfer Ratio (Min): 200% @ 5mA (mandatory match)
• Operating Temperature: -55°C ~ 125°C (mandatory match)

Secondary Compatibility Parameters:

• Voltage - Output (Max): 20V
• Current - Output / Channel: 40mA
• Voltage - Forward (Vf) (Typ): 1.4V
• Current - DC Forward (If) (Max): 10 mA
• Vce Saturation (Max): 110mV

The substitute parts are grouped into two categories based on channel configuration: 2-channel equivalents (5962-8978501PA, HCPL-5730) and 1-channel alternatives (HCPL-5700, HCPL-5701). Channel count variation affects circuit design integration but does not prevent substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

2-Channel Direct Equivalents:

5962-8978501PA and HCPL-5730 are direct parametric equivalents to the 5962-8978503KPC with identical channel configuration. Both maintain all electrical and thermal specifications. The primary distinction is RoHS compliance: 5962-8978501PA is RoHS non-compliant, while HCPL-5730 is ROHS3 compliant. For applications requiring RoHS3 compliance, HCPL-5730 is the appropriate selection. For legacy systems without compliance requirements, 5962-8978501PA provides equivalent functionality.

1-Channel Alternatives:

HCPL-5700 and HCPL-5701 are single-channel variants with identical electrical and thermal parameters. Both are ROHS3 compliant. These parts are suitable for applications requiring only one isolation channel or where circuit design permits independent channel implementation. Channel count reduction does not affect the electrical performance of individual channels.

Compliance Considerations:

All substitute parts except 5962-8978501PA are ROHS3 compliant. Selection should align with production and end-use compliance mandates. All parts maintain identical isolation voltage, current transfer ratio, switching times, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can HCPL-5700 or HCPL-5701 replace the 5962-8978503KPC in a 2-channel application?

A: HCPL-5700 and HCPL-5701 are single-channel devices. Direct replacement in a 2-channel circuit requires two separate components. Electrical performance per channel is identical; circuit design must accommodate dual-package implementation.

Q: What is the difference between 5962-8978501PA and HCPL-5730?

A: Both are 2-channel equivalents with identical electrical specifications. The difference is RoHS compliance: 5962-8978501PA is RoHS non-compliant, while HCPL-5730 is ROHS3 compliant. All other parameters are equivalent.

Q: Are all substitute parts pin-compatible with the 5962-8978503KPC?

A: All substitute parts use the same 8-DIP (0.300", 7.62mm) package and through-hole mounting. Pin compatibility depends on channel configuration: 2-channel parts (5962-8978501PA, HCPL-5730) are directly pin-compatible; 1-channel parts (HCPL-5700, HCPL-5701) have different pinout due to reduced channel count.

Q: Do all parts support the same operating temperature range?

A: Yes. All parts operate across -55°C to 125°C, maintaining identical thermal specifications.

Q: Which substitute part has the highest inventory availability?

A: HCPL-5700 has the highest inventory at 2160 pieces. HCPL-5701 has 1250 pieces. Both 2-channel alternatives (5962-8978501PA and HCPL-5730) have 914 pieces each.

Q: Can I use a 1-channel part in place of a 2-channel part?

A: Only if your circuit design permits independent channel implementation using two separate 1-channel devices. Single 1-channel parts cannot provide 2-channel functionality in designs requiring simultaneous dual-channel operation.
