HT05CB102K Equivalent & Substitute Parts

Part Overview

The HT05CB102K is a 1000 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET in a radial through-hole package. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and repair applications. The part operates across an extended temperature range of -55°C to 200°C, making it suitable for high-temperature industrial environments. Equivalent substitutes must maintain identical electrical specifications while accommodating potential physical dimension variations within acceptable assembly tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to core electrical parameters: capacitance value, voltage rating, tolerance, and temperature coefficient. All identified substitutes maintain 1000 pF capacitance, 100V voltage rating, ±10% tolerance, and X7R temperature coefficient specifications.

Physical dimensions and lead configurations are secondary considerations. Substitutes are grouped into two categories based on lead spacing compatibility:

Standard Lead Spacing (0.100" / 2.54mm): Parts MR041C102KAA and SR151C102KAA are directly compatible with PCB layouts designed for the HT05CB102K standard lead spacing.

Alternate Lead Spacing (0.200" / 5.08mm): Part MR051C102KAA features non-standard lead spacing and requires PCB layout verification before substitution.

Operating temperature range variations exist among substitutes. The HT05CB102K operates to 200°C, while KYOCERA AVX alternatives operate to 125°C maximum. Selection must account for application temperature requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SR151C102KAA

The SR151C102KAA from KYOCERA AVX SkyCap® SR series is the preferred substitute. This part maintains identical electrical specifications, standard lead spacing (0.100"), and straight lead configuration. The SR151C102KAA holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Physical dimensions are compact (0.150" L x 0.100" W), facilitating integration into space-constrained layouts. Current inventory of 4946 units supports immediate procurement.

Secondary Recommendation: MR041C102KAA

The MR041C102KAA from KYOCERA AVX Ceralam® MR series provides equivalent electrical performance with standard lead spacing. This part maintains active status and supports general-purpose applications. Physical dimensions (0.190" L x 0.090" W) are slightly larger than SR151C102KAA but remain compatible with standard PCB layouts. Inventory of 954 units is available.

Conditional Recommendation: MR051C102KAA

The MR051C102KAA is suitable only when PCB layouts accommodate 0.200" (5.08mm) lead spacing and formed lead configuration. This part is not recommended as a direct replacement for standard 0.100" lead spacing designs without PCB modification. Inventory of 616 units is available.

Temperature Range Consideration

All KYOCERA AVX substitutes operate to 125°C maximum, compared to the HT05CB102K specification of 200°C. Applications requiring operation above 125°C require alternative sourcing or design modification.

Frequently Asked Questions (FAQ)

Q: Can SR151C102KAA directly replace HT05CB102K without PCB modification?

A: Yes. The SR151C102KAA maintains identical electrical specifications (1000 pF, 100V, ±10%, X7R) and standard lead spacing (0.100"). Physical dimensions are smaller, requiring no PCB layout changes. Straight lead configuration matches the original design.

Q: What is the primary difference between MR041C102KAA and SR151C102KAA?

A: Both parts share identical electrical specifications and lead spacing. The primary differences are physical dimensions and series designation. SR151C102KAA is more compact (0.150" L vs. 0.190" L) and holds ROHS3 compliance, while MR041C102KAA does not.

Q: Is MR051C102KAA compatible with existing PCB designs?

A: MR051C102KAA is compatible only if the PCB layout accommodates 0.200" lead spacing. The original HT05CB102K uses 0.100" spacing. MR051C102KAA also features formed leads rather than straight leads, requiring additional verification of lead bend radius and PCB hole positioning.

Q: What compliance differences exist among substitutes?

A: SR151C102KAA is ROHS3 compliant and REACH unaffected. MR041C102KAA and MR051C102KAA are RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must specify SR151C102KAA.

Q: Can substitutes operate at 200°C like the original part?

A: No. All KYOCERA AVX substitutes are rated to 125°C maximum operating temperature. The HT05CB102K operates to 200°C. Applications requiring 200°C operation cannot use these substitutes without design modification or alternative sourcing.

Q: What is the inventory status for each substitute?

A: SR151C102KAA has 4946 units in stock (highest availability). MR041C102KAA has 954 units. MR051C102KAA has 616 units. The original HT05CB102K has 708 units remaining.

Q: Are all substitutes suitable for general-purpose applications?

A: Yes. All substitutes are rated for general-purpose applications with identical electrical specifications. Selection should be based on PCB layout compatibility (lead spacing), compliance requirements, and temperature range needs.
