TLP127(MAT-M-TPL,F) Equivalent & Substitute Parts

Part Overview

The TLP127(MAT-M-TPL,F) is a single-channel optoisolator with Darlington output manufactured by Toshiba Semiconductor and Storage. This component provides 2500Vrms isolation voltage and is designed for DC input applications requiring galvanic isolation. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP127(MAT-M-TPL,F) is determined by the following critical parameters:

• Single-channel Darlington output optoisolator configuration
• Minimum isolation voltage of 2500Vrms
• Current transfer ratio minimum of 1000% @ 1mA
• Maximum output voltage of 300V
• Maximum output current of 150mA per channel
• DC input type
• Surface mount technology
• Operating temperature range compatibility

The TLP187(TPL,E) qualifies as a direct substitute based on these parameters. While it offers enhanced isolation voltage (3750Vrms) and extended temperature range (-55°C ~ 110°C), all critical electrical and mechanical specifications meet or exceed the requirements of the original part.

Engineering Selection Recommendations

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

• The TLP187(TPL,E) maintains active product status with Toshiba, ensuring long-term availability and supply chain continuity.
• All critical electrical parameters are equivalent or superior to the original part.
• The substitute provides higher isolation voltage (3750Vrms vs. 2500Vrms), offering additional safety margin in isolation-critical applications.
• Extended operating temperature range (-55°C ~ 110°C) provides broader environmental compatibility.
• Both parts carry identical ECCN classification (EAR99) and MSL rating (1 - Unlimited).
• RoHS3 compliance of the substitute ensures regulatory alignment with current manufacturing standards.

Package differences exist between the original 6-MFSOP (Gull Wing) and substitute 6-SOP configuration. PCB layout and footprint modifications are required for implementation.

Frequently Asked Questions (FAQ)

Q: Can the TLP187(TPL,E) be used as a direct pin-for-pin replacement?

A: The TLP187(TPL,E) is electrically equivalent but not a pin-for-pin replacement. The original part uses a 6-MFSOP (4 Leads) Gull Wing package, while the substitute uses a 6-SOIC (0.173", 4.40mm Width) package. PCB footprint redesign is required.

Q: What are the key differences between these parts?

A: The primary differences are isolation voltage (2500Vrms vs. 3750Vrms), operating temperature range (-55°C ~ 100°C vs. -55°C ~ 110°C), package type (6-MFSOP vs. 6-SOP), and product status (Obsolete vs. Active). All critical electrical performance parameters are identical.

Q: Is the higher isolation voltage of the TLP187(TPL,E) a concern for compatibility?

A: No. Higher isolation voltage is a beneficial characteristic that exceeds the original specification. Applications designed for 2500Vrms isolation will operate safely with 3750Vrms isolation.

Q: Are there any compliance or certification differences?

A: Both parts share identical ECCN (EAR99) and MSL (1 - Unlimited) classifications. The TLP187(TPL,E) includes RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Q: What inventory considerations apply to this substitution?

A: The TLP187(TPL,E) has 2250 pieces in stock as new original inventory, compared to 935 pieces for the obsolete TLP127(MAT-M-TPL,F). The active product status ensures ongoing availability.
