Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T110D107K020AS is determined by strict alignment with the following critical parameters:

Critical Matching Parameters:

• Capacitance value: 100 µF (exact match required)
• Rated voltage: 20 V (exact match required)
• Tolerance: ±10% (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Axial (exact match required)
• Operating temperature range: -55°C to 125°C (exact match or wider range acceptable)

Application-Dependent Parameters:

• ESR (Equivalent Series Resistance): 600 mOhm specification applies to the main part; substitute parts with unspecified ESR values remain functionally compatible if all critical parameters align
• Encapsulation type (hermetically sealed vs. molded): Both construction methods are acceptable for general-purpose applications; selection depends on environmental exposure requirements

The substitute part 173D107X9020YWE3 (Vishay Sprague TANTALEX™ 173D series) satisfies all critical matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The T110D107K020AS and 173D107X9020YWE3 are electrically and mechanically equivalent for applications requiring 100 µF capacitance at 20 V with ±10% tolerance in through-hole axial configuration. Both components maintain identical operating temperature specifications (-55°C to 125°C) and are classified as Active products.

Compliance Considerations:

The 173D107X9020YWE3 (Vishay Sprague) offers ROHS3 compliance, whereas the T110D107K020AS (KEMET) is RoHS non-compliant. Selection between these parts should account for regulatory requirements applicable to the end application and target market.

Construction Type Variance:

The T110D107K020AS employs hermetically sealed construction, while the 173D107X9020YWE3 uses molded construction. Both construction methods are suitable for general-purpose applications. Hermetically sealed designs provide enhanced moisture barrier properties; molded designs offer compact form factors. Selection depends on environmental exposure conditions and space constraints within the circuit board layout.

Physical Dimensions:

The 173D107X9020YWE3 exhibits a smaller physical footprint (0.280" Dia x 0.550" L) compared to the T110D107K020AS (0.351" Dia x 0.786" L). This dimensional difference may influence board layout compatibility and should be verified against mechanical constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 173D107X9020YWE3 be used as a direct replacement for the T110D107K020AS?

A: Yes. Both components share identical electrical specifications (100 µF, 20 V, ±10% tolerance) and mounting characteristics (through-hole axial). The substitute part is functionally equivalent for general-purpose applications. Physical dimensions differ; verify board layout compatibility before implementation.

Q: What is the significance of the ESR difference between these parts?

A: The T110D107K020AS specifies 600 mOhm ESR; the 173D107X9020YWE3 does not provide an ESR specification. For applications where ESR is a critical design parameter (high-frequency filtering, low-impedance power supply decoupling), the unspecified ESR of the substitute part requires verification against application requirements before selection.

Q: Does the construction type difference (hermetically sealed vs. molded) affect substitution eligibility?

A: Both construction types are acceptable for general-purpose applications. Hermetically sealed construction (T110D107K020AS) provides superior moisture protection in high-humidity or corrosive environments. Molded construction (173D107X9020YWE3) offers compact dimensions. Selection depends on environmental exposure and space constraints specific to the application.

Q: Are there RoHS compliance implications when substituting these parts?

A: Yes. The T110D107K020AS is RoHS non-compliant; the 173D107X9020YWE3 is ROHS3 compliant. Applications subject to RoHS regulations (EU markets, certain industries) require the compliant substitute. Applications without RoHS requirements may use either part.

Q: How do the physical dimensions affect PCB layout?

A: The 173D107X9020YWE3 is physically smaller (0.280" Dia x 0.550" L vs. 0.351" Dia x 0.786" L). This allows for more compact board layouts but requires verification that the smaller footprint does not conflict with existing component placement, lead spacing, or mechanical clearance requirements in the target circuit board design.

Q: Are both parts suitable for the full operating temperature range of -55°C to 125°C?

A: Yes. Both the T110D107K020AS and 173D107X9020YWE3 are rated for identical operating temperature ranges (-55°C to 125°C) and are suitable for applications requiring operation across this full temperature spectrum.

Q: What packaging formats are available for these parts?

A: The T110D107K020AS is supplied in Bulk packaging. The 173D107X9020YWE3 is supplied in Cut Tape (CT) packaging. Packaging format selection depends on procurement volume requirements and assembly process compatibility.
