HT55BB103KN Equivalent & Substitute Parts

Part Overview

The HT55BB103KN is a 10000 pF ceramic capacitor manufactured by KEMET, rated for 50V with X7R temperature coefficient and radial through-hole mounting. This component is designed for general-purpose applications requiring high-temperature operation across -55°C to 200°C. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for direct board-level substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55BB103KN is determined by strict equivalence across seven critical parameters: capacitance value, voltage rating, tolerance specification, temperature coefficient classification, operating temperature range, mounting configuration, and lead spacing. These parameters define the functional and physical compatibility of ceramic capacitors within high-temperature applications.

The substitute part C052H103K5R5GA meets all substitution criteria through identical electrical specifications (10000 pF, ±10%, 50V, X7R) and compatible mechanical configuration (through-hole radial, 0.200" lead spacing). The substitute maintains the full operating temperature range of -55°C to 200°C required for the original application.

Parameter Comparison

Engineering Selection Recommendations

The C052H103K5R5GA is the qualified substitute for the obsolete HT55BB103KN based on complete electrical and mechanical parameter equivalence. Both components are manufactured by KEMET and share identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature specifications. The lead spacing of 0.200" (5.08mm) ensures direct PCB footprint compatibility without layout modification.

The substitute part offers two additional advantages: active product status with current manufacturing availability and ROHS3 compliance, compared to the obsolete status and RoHS non-compliance of the original part. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can C052H103K5R5GA be used as a direct replacement for HT55BB103KN without PCB modification?

A: Yes. Both parts share identical lead spacing (0.200" / 5.08mm), radial through-hole configuration, and formed lead style. Physical footprint compatibility is confirmed.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Capacitance (10000 pF), voltage rating (50V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C) are identical.

Q: What is the primary reason for substitution?

A: The HT55BB103KN is obsolete. The C052H103K5R5GA is an active product with current manufacturing availability from KEMET.

Q: Does the substitute part meet modern compliance requirements?

A: The C052H103K5R5GA is ROHS3 compliant, whereas the original part is RoHS non-compliant. Both maintain REACH Unaffected status.

Q: Are there dimensional differences between the parts?

A: Minor dimensional variations exist in body length (0.200" vs 0.190") and height (0.200" vs 0.245"), but lead spacing remains identical at 0.200" (5.08mm), ensuring PCB compatibility.

Q: What applications are supported by the substitute part?

A: The substitute is rated for bypass and decoupling applications in addition to general-purpose use, maintaining full compatibility with the original part's intended function.
