Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Compatibility Parameters:

• Single-channel Darlington output configuration
• Minimum 2500Vrms isolation voltage capability
• 300V maximum output voltage rating
• 150mA output current per channel
• Minimum 1000% current transfer ratio @ 1mA
• Surface mount packaging with 4-lead configuration
• Operating temperature range encompassing -55°C to 100°C

The TLP187(TPL,E meets these substitution criteria while offering enhanced specifications in isolation voltage (3750Vrms) and extended operating temperature range (-55°C to 110°C). Both components maintain identical electrical performance in critical parameters including output voltage, output current, current transfer ratio, and switching characteristics.

Engineering Selection Recommendations

The TLP187(TPL,E is the active substitute for the obsolete TLP127(CANOD-TPL,F. Selection of the TLP187(TPL,E is supported by the following factors:

Product Status: The TLP187(TPL,E maintains active product status with confirmed inventory availability (2250 Pcs), ensuring long-term supply chain viability compared to the obsolete TLP127(CANOD-TPL,F.

Regulatory Compliance: The TLP187(TPL,E carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for component procurement and system deployment.

Electrical Performance: Both components maintain identical performance in critical switching parameters (turn-on/turn-off time, rise/fall time) and output specifications (voltage, current, saturation voltage). The TLP187(TPL,E provides enhanced isolation voltage (3750Vrms versus 2500Vrms), offering additional safety margin in high-voltage isolation applications.

Temperature Range: The TLP187(TPL,E extends the upper operating temperature limit to 110°C, providing improved thermal performance margin for applications operating near the TLP127(CANOD-TPL,F maximum of 100°C.

Package Consideration: The TLP187(TPL,E uses 6-SOIC packaging versus the 6-MFSOP gull wing format of the TLP127(CANOD-TPL,F. PCB layout modifications are required to accommodate the different package footprint.

Frequently Asked Questions (FAQ)

Q: Can the TLP187(TPL,E directly replace the TLP127(CANOD-TPL,F without circuit modifications?

A: Electrical substitution is valid based on identical output voltage, output current, current transfer ratio, and switching characteristics. However, the package format differs (6-SOIC versus 6-MFSOP gull wing), requiring PCB layout and footprint redesign.

Q: What is the significance of the higher isolation voltage rating on the TLP187(TPL,E?

A: The TLP187(TPL,E provides 3750Vrms isolation versus 2500Vrms on the TLP127(CANOD-TPL,F. This represents a 50% increase in isolation capability, offering additional safety margin and design flexibility for high-voltage isolation applications.

Q: Are there any input or output characteristic differences between these components?

A: Input type (DC) and output type (Darlington) are identical. The forward voltage (Vf) differs slightly (1.15V versus 1.25V typical), representing a 0.1V variance within normal component tolerance ranges.

Q: Does the TLP187(TPL,E meet current environmental and regulatory standards?

A: Yes. The TLP187(TPL,E is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The TLP127(CANOD-TPL,F compliance status is not specified.

Q: What packaging considerations apply when substituting these components?

A: The TLP127(CANOD-TPL,F uses 6-MFSOP (4 Lead) gull wing surface mount packaging. The TLP187(TPL,E uses 6-SOIC (0.173", 4.40mm Width) surface mount packaging. Different footprints require PCB redesign and revalidation of assembly processes.

Q: Is the TLP187(TPL,E suitable for applications requiring the full -55°C to 100°C temperature range?

A: Yes. The TLP187(TPL,E operating range of -55°C to 110°C encompasses the full TLP127(CANOD-TPL,F specification range, with additional margin at the upper temperature limit.
