TLP127(CANO-U,F) Equivalent & Substitute Parts

Part Overview

The TLP127(CANO-U,F) is a photocoupler optoisolator with Darlington output manufactured by Toshiba Electronic Devices and Storage Corporation. This component provides galvanic isolation up to 2500Vrms with a single channel configuration in a 6-MFSOP surface mount package. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLP127(CANO-U,F) is determined by the following critical parameters:

• Isolation Voltage: Minimum 2500Vrms (equal or higher acceptable)
• Number of Channels: 1 channel (single channel configuration required)
• Output Type: Darlington configuration
• Current Transfer Ratio: Minimum 1000% @ 1mA
• Maximum Output Voltage: 300V or higher
• Output Current Capability: 150mA or higher per channel
• Switching Characteristics: Turn-on/turn-off times of 50µs/15µs or faster
• Mounting Type: Surface mount technology
• Input Type: DC input

The TLP187(TPL,E) meets all substitution criteria with enhanced isolation voltage (3750Vrms), extended operating temperature range, and active product status. Package differences require PCB layout evaluation but do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The TLP187(TPL,E) is the qualified substitute for the obsolete TLP127(CANO-U,F). Selection is based on the following engineering factors:

• Product Availability: The TLP187(TPL,E) maintains active manufacturing status with 2250 units in stock, ensuring supply chain continuity for the obsolete TLP127(CANO-U,F).
• Electrical Equivalence: All critical electrical parameters match or exceed the original specification, including isolation voltage, current transfer ratio, output voltage, and switching characteristics.
• Compliance Status: The TLP187(TPL,E) is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Package Consideration: The TLP187(TPL,E) uses a 6-SOIC package instead of the 6-MFSOP gull wing package. PCB layout modification is required for footprint compatibility.
• Temperature Performance: The extended operating range (-55°C ~ 110°C) of the TLP187(TPL,E) provides additional margin over the original -55°C ~ 100°C specification.

Frequently Asked Questions (FAQ)

Q: Can the TLP187(TPL,E) directly replace the TLP127(CANO-U,F) without PCB modifications?

A: Electrical substitution is direct. However, the package change from 6-MFSOP gull wing to 6-SOIC requires PCB footprint redesign. Pin functionality and electrical characteristics remain compatible.

Q: What is the isolation voltage difference between these parts?

A: The TLP187(TPL,E) provides 3750Vrms isolation compared to 2500Vrms for the TLP127(CANO-U,F). This higher isolation voltage is compatible with applications designed for the lower specification.

Q: Are the switching characteristics identical?

A: Yes. Both parts specify 50µs turn-on time and 15µs turn-off time, with identical 40µs and 15µs rise/fall times.

Q: Does the forward voltage difference affect circuit design?

A: The TLP187(TPL,E) forward voltage is 1.25V compared to 1.15V for the TLP127(CANO-U,F). This 0.1V difference is minimal and does not require circuit redesign for standard DC input applications.

Q: What compliance certifications apply to the substitute part?

A: The TLP187(TPL,E) is ROHS3 compliant and REACH unaffected. The original TLP127(CANO-U,F) compliance status is not specified in available documentation.

Q: Is the moisture sensitivity level the same?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
