Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT6-X007 is determined by the following critical parameters:

• Number of Channels: Must be 2 (dual-channel configuration)
• Output Type: Must be Transistor
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 8-SMD, Gull Wing
• Voltage - Isolation: Minimum 5000Vrms (MCT6-X007 specifies 5300Vrms)
• Current - Output / Channel: Minimum 30mA
• Vce Saturation (Max): 400mV or lower
• Operating Temperature Range: Must encompass or match -55°C ~ 100°C
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories based on packaging format: Tube packaging (MCT6SM, MCT9001S) and Tape & Reel packaging (MCT6SMT&R, MCT9001SD). All substitute parts maintain the same electrical isolation class, channel configuration, and output characteristics required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain Active product status, ensuring long-term availability and supply chain stability compared to the MCT6-X007 Last Time Buy designation. All substitutes are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting environmental and handling requirements equivalent to the original part.

MCT6SM and MCT6SMT&R (Isocom Components 2004 LTD) provide direct electrical equivalence with 5300Vrms isolation voltage matching the MCT6-X007. These parts differ in packaging format: MCT6SM is supplied in Tube format, while MCT6SMT&R is supplied in Tape & Reel format. Both support higher output current (50mA per channel versus 30mA), providing design margin for applications with increased current demands. Operating temperature range is -25°C ~ 100°C, which covers the upper portion of the MCT6-X007 range but does not extend to -55°C minimum.

MCT9001S and MCT9001SD (onsemi) provide alternative substitution with 5000Vrms isolation voltage, 300Vrms lower than the MCT6-X007. These parts feature higher output voltage capability (55V maximum versus 30V) and improved current transfer ratio (50% @ 5mA versus 20% @ 10mA). Operating temperature range extends to -55°C ~ 100°C, matching the MCT6-X007 specification. MCT9001S is supplied in Tube format, while MCT9001SD is supplied in Tape & Reel format.

Selection between Isocom and onsemi substitutes depends on isolation voltage requirements. Applications requiring 5300Vrms isolation must use MCT6SM or MCT6SMT&R. Applications tolerating 5000Vrms isolation may use MCT9001S or MCT9001SD, which offer superior performance characteristics and extended low-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can MCT6SM or MCT6SMT&R be used as direct replacements for MCT6-X007?

A: MCT6SM and MCT6SMT&R are functionally equivalent to MCT6-X007 for applications operating within the -25°C ~ 100°C temperature range. Both maintain 5300Vrms isolation voltage, dual-channel transistor output configuration, and 8-SMD Gull Wing package compatibility. The primary difference is packaging format: MCT6SM uses Tube packaging, while MCT6SMT&R uses Tape & Reel format. Applications requiring operation below -25°C must use MCT9001S or MCT9001SD.

Q: What is the difference between MCT9001S and MCT9001SD?

A: MCT9001S and MCT9001SD are electrically identical. The difference is packaging format: MCT9001S is supplied in Tube packaging, while MCT9001SD is supplied in Tape & Reel (TR) format. Both provide 5000Vrms isolation voltage, dual-channel transistor output, and 8-SMD Gull Wing package configuration. Selection depends on assembly process requirements and inventory management preferences.

Q: Why does MCT6-X007 show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued the part and existing inventory represents the final production run. This status necessitates identifying active substitute parts to ensure design continuity and supply chain reliability for future production requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All four substitute parts (MCT6SM, MCT6SMT&R, MCT9001S, MCT9001SD) are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of MCT6-X007.

Q: What is the minimum isolation voltage requirement for substitution?

A: The MCT6-X007 specifies 5300Vrms isolation voltage. MCT6SM and MCT6SMT&R maintain this specification. MCT9001S and MCT9001SD provide 5000Vrms isolation, which is 300Vrms lower. Applications with isolation voltage requirements below 5300Vrms may use onsemi parts; applications requiring 5300Vrms must use Isocom parts.

Q: Can MCT9001S or MCT9001SD be used in applications requiring -55°C minimum operating temperature?

A: MCT9001S and MCT9001SD support -55°C ~ 100°C operating temperature range, matching MCT6-X007 specification. MCT6SM and MCT6SMT&R support only -25°C ~ 100°C range. For applications requiring -55°C minimum operation, use MCT9001S or MCT9001SD.
