Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6N139#060 is determined by the following critical parameters:

• Package / Case: 8-DIP (0.300", 7.62mm) — mechanical and electrical pin compatibility
• Number of Channels: 1 — functional equivalence
• Output Type: Darlington with Base — circuit interface requirement
• Voltage - Isolation: Minimum 3750Vrms — isolation specification floor
• Current - Output / Channel: 60mA — load-driving capability
• Voltage - Output (Max): 18V — maximum output voltage rating
• Current Transfer Ratio (Min): 500% @ 1.6mA — minimum gain specification
• Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C

Substitute parts meeting all these criteria are functionally interchangeable in applications designed for the 6N139#060.

Engineering Selection Recommendations

6N139-000E (Broadcom Limited) — Direct Replacement

The 6N139-000E is the primary substitute for the discontinued 6N139#060. Both parts share identical electrical specifications, including isolation voltage (3750Vrms), current transfer ratio range (500% to 2600% @ 1.6mA), and switching characteristics (200ns turn-on, 2µs turn-off). The 6N139-000E is currently in active production status with 1749 units in stock. The primary distinction is packaging format (tube versus unspecified for the original part) and RoHS compliance status (ROHS3 Compliant versus non-compliant). This part is the recommended direct replacement for applications where the original 6N139#060 was specified.

6N139 (Texas Instruments) — Parametric Equivalent with Enhanced Specifications

The Texas Instruments 6N139 provides parametric equivalence with enhanced isolation voltage (5300Vrms versus 3750Vrms), supporting applications requiring higher isolation margins. The part maintains identical output characteristics (18V maximum, 60mA per channel) and minimum current transfer ratio (500% @ 1.6mA). Switching performance differs slightly (600ns turn-on, 1.5µs turn-off versus 200ns and 2µs), and the operating temperature range is extended (-55°C ~ 100°C versus -40°C ~ 85°C). This part is suitable for designs where enhanced isolation voltage provides system-level benefits. The part is currently in active production with 81100 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 6N139-000E directly replace the 6N139#060 in existing designs?

A: Yes. The 6N139-000E is electrically and mechanically identical to the 6N139#060. Both parts feature 3750Vrms isolation, identical current transfer ratio specifications (500% to 2600% @ 1.6mA), matching output voltage and current ratings, and the same 8-DIP package. The 6N139-000E is the recommended direct replacement.

Q: What are the differences between the Broadcom 6N139-000E and Texas Instruments 6N139?

A: The primary differences are isolation voltage (3750Vrms versus 5300Vrms), switching speed (200ns/2µs versus 600ns/1.5µs turn-on/turn-off times), and operating temperature range (-40°C ~ 85°C versus -55°C ~ 100°C). Both parts maintain identical output specifications and current transfer ratio minimums. The Texas Instruments part provides higher isolation voltage and extended temperature range.

Q: Are there any RoHS compliance considerations when selecting a substitute?

A: The original 6N139#060 is RoHS non-compliant. The 6N139-000E is ROHS3 Compliant, making it suitable for applications with RoHS requirements. The Texas Instruments 6N139 is RoHS non-compliant. Compliance requirements should be evaluated against system-level specifications.

Q: Can the Texas Instruments 6N139 be used in applications designed for the 6N139#060?

A: Yes, with design review. The Texas Instruments part meets all critical electrical parameters (output voltage, current, isolation voltage minimum, current transfer ratio minimum) and uses the same 8-DIP package. The enhanced isolation voltage (5300Vrms) and extended temperature range provide additional design margin. Switching time differences (600ns versus 200ns turn-on) should be evaluated for timing-critical applications.

Q: What is the significance of the 8-DIP package specification?

A: The 8-DIP (0.300", 7.62mm) package ensures mechanical and electrical pin compatibility across all substitute parts. This package format is standard for through-hole mounting on printed circuit boards and maintains identical pinout and spacing for direct board-level substitution.

Q: Are all substitute parts available in the same packaging format?

A: The 6N139-000E is supplied in tube packaging. The original 6N139#060 packaging format is not specified in the available data. The Texas Instruments 6N139 packaging format is not specified. Packaging format should be confirmed with the supplier for procurement and handling requirements.
