Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT13BW104KC is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitutes:

Electrical Parameters (Must Match):

• Capacitance: 0.1 µF
• Tolerance: ±10%
• Voltage Rating: 50V (minimum)
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 200°C (minimum)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package Type: Axial
• Lead Style: Straight

The ARA25B104KWS meets all electrical and mechanical requirements for direct substitution. Both components are manufactured by KEMET and share identical electrical specifications. The primary distinction is product status: the HT13BW104KC is obsolete while the ARA25B104KWS is active, making the latter the appropriate replacement for ongoing applications.

Parameter Comparison

Engineering Selection Recommendations

The ARA25B104KWS is the direct substitute for the HT13BW104KC. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components provide identical electrical performance with 0.1 µF capacitance, 50V rating, X7R temperature coefficient, and -55°C to 200°C operating range. No functional differences exist in circuit operation.

Mechanical Compatibility: Both components utilize axial through-hole mounting with straight leads, ensuring PCB layout compatibility without modification.

Product Status: The ARA25B104KWS is active and currently in production, providing assured long-term availability. The HT13BW104KC is obsolete and subject to inventory depletion.

Compliance Alignment: Both components share identical RoHS non-compliance status, maintaining consistency with existing design documentation and supply chain requirements.

Physical Dimensions: While dimensional specifications differ slightly (HT13BW104KC: 3.43mm x 7.26mm versus ARA25B104KWS: 2.54mm x 6.86mm), both components are axial packages suitable for standard through-hole PCB applications. PCB layout verification is recommended to confirm lead spacing compatibility with existing footprints.

Frequently Asked Questions (FAQ)

Q: Can the ARA25B104KWS directly replace the HT13BW104KC without circuit modification?

A: Yes. Both components share identical electrical specifications (0.1 µF, 50V, X7R, -55°C to 200°C) and mechanical mounting characteristics (through-hole axial). No circuit modifications are required.

Q: Are there physical size differences between these components?

A: Yes. The HT13BW104KC measures 0.135" diameter x 0.286" length (3.43mm x 7.26mm), while the ARA25B104KWS measures 0.100" square x 0.270" length (2.54mm x 6.86mm). The ARA25B104KWS is physically smaller. Verify PCB footprint compatibility before implementation.

Q: Why is the HT13BW104KC listed as obsolete?

A: The HT13BW104KC is no longer in active production. The ARA25B104KWS represents the current active equivalent from KEMET's product line.

Q: Do both components have the same RoHS compliance status?

A: Yes. Both the HT13BW104KC and ARA25B104KWS are RoHS non-compliant, maintaining identical regulatory status.

Q: What is the tolerance specification for these capacitors?

A: Both components carry ±10% tolerance, meaning the actual capacitance value will fall within 0.09 µF to 0.11 µF at rated conditions.

Q: Are these components suitable for high-temperature applications?

A: Yes. Both components operate across -55°C to 200°C with X7R temperature coefficient, providing stable capacitance performance across this extended temperature range for high-temperature industrial applications.

Q: What is the voltage derating consideration for these 50V components?

A: Both components are rated for 50V maximum. Circuit design should account for appropriate voltage derating margins based on application requirements and reliability standards.
