Key Parameters

Substitute Part Grouping Explanation

The MCT61XSM qualifies as a parametric equivalent to the MCT61SM based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Number of Channels: 2 (both parts)
• Voltage - Isolation: 5300Vrms (both parts)
• Current Transfer Ratio (Min): 50% @ 5mA (both parts)
• Output Type: Transistor (both parts)
• Voltage - Output (Max): 30V (both parts)
• Current - Output / Channel: 50mA (both parts)
• Vce Saturation (Max): 400mV (both parts)
• Operating Temperature: -25°C ~ 100°C (both parts)
• Package / Case: 8-SMD, Gull Wing (both parts)
• RoHS Status: ROHS3 Compliant (both parts)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (both parts)

All electrical performance parameters, thermal operating range, and physical packaging specifications are identical between the main part and substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both MCT61SM and MCT61XSM are active production parts manufactured by Isocom Components 2004 LTD with identical electrical specifications and compliance certifications. Selection between these parts should be based on inventory availability and supply chain requirements. The MCT61XSM offers higher stock availability at 1102 units compared to 674 units for the MCT61SM. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The identical electrical performance, thermal operating range, and physical packaging ensure direct functional interchangeability in circuit applications.
