Substitute Part Grouping Explanation

Substitute parts for the TIL111 are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

Identical number of channels (1 channel)
Matching isolation voltage rating (7.5Vpk)
Identical current transfer ratio minimum specification (20% @ 16mA)
Matching output type (Transistor with Base)
Identical maximum output voltage (30V)
Identical maximum output current per channel (50mA)
Matching forward voltage (1.2V typical)
Identical maximum forward current (60mA)
Matching Vce saturation specification (400mV maximum)
Identical operating temperature range (-55°C ~ 100°C)
Same package and case format (6-DIP, 0.300", 7.62mm)
Through-hole mounting type
ROHS3 compliance maintained
MSL rating of 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in circuit applications designed for the TIL111.

Engineering Selection Recommendations

All three parts—TIL111, TIL111X, and TIL114X—maintain active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these optoisolators should be based on availability and packaging requirements. The TIL111 is supplied in standard packaging, while TIL111X and TIL114X are supplied in tube packaging. All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The primary distinction between TIL111 and TIL114X is the series designation; however, all electrical and mechanical parameters remain identical, confirming functional interchangeability. Inventory levels vary across the three parts, with TIL111 offering the highest stock availability at 5561 units.

Frequently Asked Questions (FAQ)

Q: Can TIL111X be used as a direct replacement for TIL111?

A: Yes. TIL111X is a parametric equivalent with identical electrical specifications, output characteristics, isolation voltage, current transfer ratio, and 6-DIP package format. The primary difference is packaging type (tube versus standard). Both parts are manufactured by Isocom Components 2004 LTD and maintain the same performance parameters.

Q: What is the difference between TIL111 and TIL114X?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The series designation differs (TIL111 versus TIL114), but all critical parameters including isolation voltage, current transfer ratio, output voltage/current ratings, and package format are identical. Both are suitable for the same circuit applications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 6-DIP (0.300", 7.62mm) package format with through-hole mounting, ensuring identical PCB footprint and pin configuration compatibility.

Q: What packaging options are available?

A: TIL111 is supplied in standard packaging. TIL111X and TIL114X are supplied in tube packaging. The electrical specifications and performance characteristics remain unchanged regardless of packaging type.

Q: Do these parts require special handling or storage conditions?

A: No. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. Standard component storage practices are sufficient.

Q: Are all parts ROHS3 compliant?

A: Yes. TIL111, TIL111X, and TIL114X are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
