TIL113300W Equivalent & Substitute Parts
Part Overview
The TIL113300W is an optoisolator with Darlington output and base connection, manufactured by onsemi. This component provides 5300Vrms isolation in a 6-DIP package and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Substitute Part Grouping Explanation
Substitute parts for the TIL113300W are qualified based on the following critical parameters:
- Identical package and pinout: 6-DIP (0.400", 10.16mm) through-hole mounting
- Matching output configuration: Darlington with Base output
- Single channel optoisolator topology
- DC input type
- Operating temperature range: -55°C ~ 100°C
- Isolation voltage rating of 5000Vrms or higher
- Current transfer ratio minimum of 300% @ 10mA or equivalent performance
- Compatible output voltage and saturation characteristics
The TIL113M (Fairchild Semiconductor) and TIL113G (Isocom Components 2004 LTD) meet these substitution criteria and are available from active manufacturers.

Engineering Selection Recommendations
The TIL113M (Fairchild Semiconductor) is the primary substitute for the obsolete TIL113300W. Both components share identical current transfer ratio specifications and operating temperature ranges. The TIL113M maintains active product status and is widely available. The higher maximum output voltage rating (55V vs. 30V) provides additional design margin in applications requiring higher collector voltage operation.
The TIL113G (Isocom Components 2004 LTD) is an alternative substitute that matches the original isolation voltage specification (5300Vrms) and maintains identical package and thermal operating range. This part is RoHS3 compliant and available in tube packaging. The TIL113G is suitable for applications where the original 5300Vrms isolation specification is a critical design requirement.
Both substitute parts are compliant with ECCN EAR99 and HTSUS 8541.49.8000 classifications, matching the regulatory status of the original component.
Frequently Asked Questions (FAQ)
Q: Can TIL113M be used as a direct replacement for TIL113300W?
A: Yes. Both components share the same 6-DIP package, pinout, single-channel Darlington output configuration, and operating temperature range. The TIL113M meets or exceeds the electrical specifications of the TIL113300W and is available from an active manufacturer.
Q: What is the difference between TIL113M and TIL113G?
A: The primary difference is isolation voltage rating. TIL113M provides 5000Vrms isolation, while TIL113G matches the original 5300Vrms specification. Both are functionally compatible in the 6-DIP package. TIL113G is RoHS3 compliant and supplied in tube packaging.
Q: Are there any output voltage limitations when substituting?
A: The TIL113M has a maximum output voltage rating of 55V compared to 30V for the original TIL113300W and TIL113G. Applications operating at or below 30V output voltage will function identically with all three parts. Applications requiring higher output voltages benefit from the TIL113M's higher rating.
Q: Is the package footprint identical across all three parts?
A: Yes. All three components use the 6-DIP (0.400", 10.16mm) through-hole package with identical pinout and mounting requirements. No PCB layout modifications are necessary when substituting between these parts.
Q: What are the key parameters that determine substitutability?
A: Substitutability is determined by matching isolation voltage (5000Vrms minimum), output configuration (Darlington with Base), package type (6-DIP), single-channel topology, DC input type, and operating temperature range (-55°C ~ 100°C). Current transfer ratio and forward voltage characteristics must be compatible with circuit design requirements.
