TAS825K075P1F Equivalent & Substitute Parts

Part Overview

The TAS825K075P1F is an 8.2 µF hermetically sealed tantalum capacitor rated for 75 V operation in an axial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system maintenance and new design integration. The combination of obsolete status and the need for continued supply makes substitute part evaluation critical for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS825K075P1F is determined by the following critical parameters:

• Capacitance Value: 8.2 µF (exact match required)
• Tolerance: ±10% (must match or be tighter)
• Voltage Rating: Minimum 75 V (equal or higher acceptable)
• Type: Hermetically sealed tantalum construction
• Mounting: Through-hole axial configuration
• Temperature Range: -55°C to 125°C (must support full range)

The identified substitute, 109D825X9100C2 (Vishay Sprague TANTALEX™ series), meets all substitution criteria with a higher voltage rating (100 V), providing enhanced safety margins in circuit applications. The axial package geometry and hermetic sealing ensure form-factor and reliability equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 109D825X9100C2 is the qualified substitute for the obsolete TAS825K075P1F. This substitution is supported by:

• Product Status: The original part is obsolete; the substitute maintains active production status, ensuring long-term availability.
• Electrical Equivalence: Identical capacitance (8.2 µF) and tolerance (±10%) with a higher voltage rating (100 V vs. 75 V), providing improved safety margins.
• Compliance Alignment: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), with matching RoHS non-compliant status, ensuring regulatory consistency.
• Package Compatibility: Both components are through-hole axial packages with hermetically sealed tantalum construction and identical operating temperature range (-55°C to 125°C).
• Dimensional Consideration: The substitute is slightly smaller (0.219" Dia x 0.608" L versus 0.289" Dia x 0.686" L), offering improved PCB layout flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 109D825X9100C2 directly replace the TAS825K075P1F? A: Yes. Both components share identical capacitance (8.2 µF), tolerance (±10%), and operating temperature range (-55°C to 125°C). The substitute's higher voltage rating (100 V) is electrically compatible with circuits designed for 75 V operation.

Q: Why is the voltage rating different? A: The substitute offers a higher voltage rating (100 V) than the original (75 V). This provides improved safety margins and is electrically compatible for direct substitution in 75 V circuit applications.

Q: Are there physical space concerns with the substitute? A: The substitute is slightly smaller in diameter and length (0.219" Dia x 0.608" L versus 0.289" Dia x 0.686" L). This reduces component footprint and may simplify PCB layout without affecting electrical performance.

Q: What is the difference between hermetically sealed and wet tantalum construction? A: The substitute (109D825X9100C2) is classified as wet tantalum, which is a type of hermetically sealed tantalum capacitor. Both the original and substitute are hermetically sealed; this distinction indicates the internal electrolyte type in the Vishay product line.

Q: Do RoHS and REACH compliance differ between parts? A: Both parts share identical compliance status: RoHS non-compliant and REACH Unaffected. Substitution does not introduce compliance changes.

Q: What is the significance of the ESR value in the substitute? A: The substitute specifies an Equivalent Series Resistance (ESR) of 6 Ohm, which is not specified for the original part. This parameter indicates low impedance characteristics typical of wet tantalum capacitors and does not affect direct substitution compatibility.
