Key Parameters

Substitute Part Grouping Explanation

The TCK-088 is identified as a substitute based on the following alignment criteria:

• Number of Lines: Both TCK-099 and TCK-088 feature 2-line common mode choke configuration
• Manufacturer Continuity: Both components are manufactured by Traco Power, ensuring design consistency and supply chain reliability
• RoHS3 Compliance: Both parts maintain ROHS3 Compliant status, satisfying regulatory requirements
• REACH Status: Both components are REACH Unaffected, maintaining environmental compliance

The TCK-088 operates as a through-hole mounted alternative with significantly higher inductance (521 µH @ 100 kHz) and includes voltage rating specifications (500V DC) and defined operating temperature range (-40°C ~ 105°C), providing enhanced electrical performance characteristics compared to the obsolete TCK-099.

Parameter Comparison

Engineering Selection Recommendations

Selection of TCK-088 as a substitute for TCK-099 is supported by the following factors:

• Product Status: TCK-088 maintains Active status with 2100 units in stock, ensuring reliable procurement availability compared to the obsolete TCK-099
• Regulatory Compliance: Both components satisfy ROHS3 and REACH requirements, maintaining compliance with current environmental and safety standards
• Manufacturer Support: Traco Power continues to support the TCK-088 product line, providing technical documentation and supply continuity

Design integration requires evaluation of mounting type transition from surface mount to through-hole configuration and accommodation of increased physical dimensions (16.00mm x 16.00mm footprint versus 6.50mm x 6.50mm).

Frequently Asked Questions (FAQ)

Q: What are the primary substitution criteria for TCK-099?

A: The TCK-099 and TCK-088 share identical 2-line common mode choke configuration and are both manufactured by Traco Power with ROHS3 compliance. Both components satisfy the core functional requirement of 2-line EMI filtering architecture.

Q: How do mounting types differ between these components?

A: TCK-099 uses surface mount packaging (6.50mm x 6.50mm), while TCK-088 employs through-hole mounting (16.00mm x 16.00mm with 12.50mm height). PCB layout redesign is required for substitution.

Q: What inductance differences exist between TCK-099 and TCK-088?

A: TCK-099 provides 4.7 µH inductance at 100 kHz, while TCK-088 provides 521 µH at 100 kHz. The significantly higher inductance of TCK-088 affects filtering characteristics and must be evaluated for circuit compatibility.

Q: Are both components compliant with current environmental standards?

A: Yes. Both TCK-099 and TCK-088 are ROHS3 Compliant and REACH Unaffected, satisfying current regulatory requirements.

Q: What is the inventory status for each component?

A: TCK-099 has 896 units in stock but is classified as obsolete. TCK-088 has 2100 units in stock and maintains active product status with ongoing manufacturer support.
