Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT08BW105KN is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1 µF
• Tolerance: ±10%
• Voltage rating: 50V minimum
• Temperature coefficient: X7R

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.400" (10.16mm)
• Lead style: Straight

The SR505C105KAA from KYOCERA AVX meets all electrical and mechanical substitution criteria. Physical dimensions may vary within acceptable tolerances for through-hole radial mounting applications, provided lead spacing and mounting footprint compatibility are maintained.

Parameter Comparison

Engineering Selection Recommendations

The SR505C105KAA serves as a direct electrical and mechanical substitute for the obsolete HT08BW105KN. Both components share identical capacitance, tolerance, voltage rating, and temperature coefficient specifications. Lead spacing and radial through-hole configuration are equivalent, ensuring PCB footprint compatibility.

The primary distinction is the operating temperature range. The HT08BW105KN operates to 200°C, while the SR505C105KAA operates to 125°C. Selection of the SR505C105KAA is appropriate for applications where the maximum operating temperature does not exceed 125°C. For applications requiring operation above 125°C, alternative substitutes from the provided list must be evaluated against the extended temperature requirement.

The SR505C105KAA is manufactured by KYOCERA AVX and maintains active product status with ROHS3 compliance, supporting long-term supply chain continuity. The component is available in bulk packaging with confirmed inventory.

Frequently Asked Questions (FAQ)

Q: Can the SR505C105KAA replace the HT08BW105KN in all applications?

A: The SR505C105KAA is electrically and mechanically equivalent for applications operating at or below 125°C. The HT08BW105KN supports operation to 200°C. Verify the maximum operating temperature requirement of your application before substitution.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Both components feature 0.400" (10.16mm) lead spacing and radial through-hole configuration. Physical dimensions vary slightly (HT08BW105KN: 0.500" L x 0.270" W; SR505C105KAA: 0.500" L x 0.200" W), but these differences do not affect PCB footprint compatibility for standard through-hole radial mounting.

Q: What compliance certifications apply to the SR505C105KAA?

A: The SR505C105KAA is ROHS3 compliant and REACH unaffected. Both components carry EAR99 export classification and HTSUS code 8532.24.0060.

Q: Why is the HT08BW105KN classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by KEMET. The SR505C105KAA from KYOCERA AVX provides functional equivalence with active manufacturing status.

Q: Are there additional substitute options available?

A: The SR505C105KAA is the primary substitute meeting all specified parameters. Additional alternatives listed in the substitute chain (SR505C105KAR, C330C105K5R5TA, SR325C105KAA, RDER71H105K2P1H03B, RDER71H105K2K1H03B) may require evaluation against specific application constraints not addressed in this reference.
