Substitute Part Grouping Explanation

Substitution eligibility for the ILQ2-X007T is determined by the following critical parameters:

Voltage - Isolation: 5300Vrms (exact match required)
Output Type: Transistor (exact match required)
Voltage - Output (Max): 70V (exact match required)
Current - Output / Channel: 50mA (exact match required)
Current Transfer Ratio range: 100% - 500% @ 10mA (exact match required)
Package / Case: 16-SMD, Gull Wing (exact match required)
Input Type: DC (exact match required)

The ILQ2-X007T features 4 channels. Substitute parts from Isocom Components 2004 LTD (ILQ2SM, ILQ2SMT&R, ILQ2XSM, ILQ2XSMT&R) are single-channel variants that meet all electrical specifications but differ in channel configuration. The parametric equivalent ILQ2-X009T from Vishay maintains identical electrical characteristics and 4-channel configuration, differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Engineering Selection Recommendations

ILQ2-X009T (Parametric Equivalent): This Vishay part maintains full electrical and functional equivalence to the ILQ2-X007T with identical 4-channel configuration. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both parts carry Last Time Buy status. Selection of ILQ2-X009T is appropriate for applications where packaging format compatibility with existing procurement processes is acceptable.

ILQ2SM, ILQ2SMT&R, ILQ2XSM, ILQ2XSMT&R (Isocom Components): These single-channel variants from Isocom Components 2004 LTD meet all critical electrical specifications including isolation voltage, output voltage, current ratings, and current transfer ratio. These parts carry Active product status, ensuring long-term availability. The primary design consideration is channel count: applications requiring 4-channel isolation must implement four separate single-channel devices in place of one ILQ2-X007T. Operating temperature range is -25°C ~ 100°C (versus -40°C ~ 100°C for the main part). All parts are ROHS3 compliant and carry REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can ILQ2SM or ILQ2SMT&R directly replace the ILQ2-X007T?

A: Electrical substitution is valid for single-channel applications. The ILQ2SM and ILQ2SMT&R meet all electrical specifications. However, the ILQ2-X007T is a 4-channel device. Applications requiring 4-channel isolation must use four separate single-channel parts or select the 4-channel ILQ2-X009T equivalent.

Q: What is the difference between ILQ2SM and ILQ2SMT&R?

A: Both parts are electrically identical. The difference is packaging: ILQ2SM is supplied in Tube packaging, while ILQ2SMT&R is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly process requirements.

Q: What is the difference between ILQ2XSM and ILQ2XSMT&R?

A: Both parts are electrically identical. The difference is packaging: ILQ2XSM is supplied in Tube packaging, while ILQ2XSMT&R is supplied in Tape & Reel (TR) format.

Q: Does the operating temperature difference affect substitution?

A: The Isocom parts operate from -25°C ~ 100°C, while the ILQ2-X007T operates from -40°C ~ 100°C. Applications requiring operation below -25°C must use the ILQ2-X009T or original ILQ2-X007T.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ILQ2-X009T and all Isocom variants (ILQ2SM, ILQ2SMT&R, ILQ2XSM, ILQ2XSMT&R) are ROHS3 compliant.

Q: Why is the ILQ2-X007T marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The ILQ2-X009T from Vishay and the Isocom variants provide electrical equivalence for ongoing design requirements.
