Key Parameters

Substitute Part Grouping Explanation

Substitution of the THF107K020P1G-F is determined by the following electrical and mechanical equivalence criteria:

Required Electrical Parameters:

• Capacitance: 100 µF (fixed requirement)
• Voltage Rating: 20 V (minimum acceptable)
• Tolerance: ±10% (electrical matching tolerance)
• Type: Hermetically Sealed (for reliability and environmental protection)
• Operating Temperature Range: -55°C to 125°C (environmental compatibility)

Required Mechanical Parameters:

• Mounting Type: Through Hole (PCB interface requirement)
• Package / Case: Axial (form factor constraint)
• Physical Dimensions: 0.351" Dia × 0.786" L (board layout compatibility)

The substitute part 150D107X9020S2B from Vishay Sprague meets all specified electrical and mechanical parameters, ensuring direct functional equivalence within the stated application constraints.

Engineering Selection Recommendations

The 150D107X9020S2B is the specified direct substitute for the obsolete THF107K020P1G-F. Selection of this alternative is driven by the following technical factors:

Product Status: The original THF107K020P1G-F is classified as obsolete, making the active-status 150D107X9020S2B essential for new procurement and system repair.

Electrical Equivalence: Both parts share identical capacitance (100 µF), voltage rating (20 V), tolerance (±10%), type (hermetically sealed), and operating temperature range (-55°C to 125°C), ensuring direct functional substitution.

Mechanical Compatibility: Both components are through-hole axial packages with identical physical dimensions (0.351" Dia × 0.786" L), permitting direct board-level replacement without layout modification.

Compliance: Both parts carry EAR99 ECCN classification. The substitute carries REACH Unaffected status, while RoHS compliance differs between the two manufacturers' specifications.

Availability: The 150D107X9020S2B maintains active inventory status from Vishay Sprague, ensuring supply reliability for ongoing applications.

Frequently Asked Questions (FAQ)

Q: Can the 150D107X9020S2B replace the THF107K020P1G-F in existing assemblies?

A: Yes. Both parts meet identical electrical specifications (100 µF, 20 V, ±10%, hermetically sealed) and mechanical parameters (through-hole axial, 0.351" Dia × 0.786" L). Direct PCB substitution is supported without circuit modification.

Q: Are there dimensional differences between these parts?

A: No. Both components share identical physical dimensions (0.351" Dia × 0.786" L / 8.92 mm × 19.96 mm), ensuring equivalent board spacing and lead positioning.

Q: What is the difference in ESR between the parts?

A: The THF107K020P1G-F specifies 75 mOhm ESR. The ESR value for the 150D107X9020S2B is not provided in the available specifications. Circuit-level ESR performance differences, if any, should be evaluated against application ripple current and frequency requirements.

Q: Do these parts have different temperature ratings?

A: No. Both components operate across the same temperature range (-55°C to 125°C), providing equivalent thermal performance.

Q: What is the difference in manufacturing series?

A: The THF107K020P1G-F belongs to the THF series (CDE). The 150D107X9020S2B is part of the TANTALEX™ 150D series (Vishay Sprague). These series designations reflect manufacturer product lines but do not affect functional compatibility.

Q: Are there RoHS compliance differences?

A: Yes. The THF107K020P1G-F is ROHS3 compliant, while the 150D107X9020S2B is listed as RoHS non-compliant. Component selection should account for application regulatory requirements.

Q: What is the availability of the substitute part?

A: The 150D107X9020S2B maintains active product status with 989 pieces in current inventory. The original THF107K020P1G-F is obsolete, making the Vishay substitute the current sourcing option.
