Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06BB105KN is determined by strict equivalence in the following parameters: capacitance value (1 µF), temperature coefficient (X7R), operating temperature range (-55°C ~ 200°C), mounting type (through hole), package type (radial), and lead spacing (0.200" / 5.08mm).

Substitute parts are grouped into two categories:

Upgrade Category: Parts with increased voltage rating (100V) that maintain all other core electrical parameters. These provide enhanced voltage margin while preserving capacitance, tolerance, temperature coefficient, and thermal operating range.

Direct Equivalent Category: Parts with identical voltage rating (50V) and electrical specifications but differing in physical dimensions, tolerance precision, or compliance certifications. These maintain full functional compatibility within the same electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ARR06B105KGS

ARR06B105KGS is the direct functional equivalent of HT06BB105KN. Both parts share identical electrical specifications: 1 µF capacitance, ±10% tolerance, 50V voltage rating, X7R temperature coefficient, and -55°C to 200°C operating range. ARR06B105KGS is active in production and maintains ROHS3 compliance, matching the regulatory status of the original part. This substitution requires no circuit redesign and provides direct pin-compatible replacement.

Secondary Recommendation: ARR07B105KGS

ARR07B105KGS provides equivalent electrical performance with ROHS3 compliance and active product status. Physical dimensions differ slightly from the original part, with a narrower body width (0.100" vs. 0.150"), but lead spacing and mounting characteristics remain compatible. This option is suitable when board space constraints permit the reduced footprint.

Upgrade Option: ARR07D105KGS

ARR07D105KGS offers increased voltage rating (100V) while maintaining all other electrical parameters. This upgrade provides enhanced voltage margin for applications where circuit conditions may exceed the original 50V specification. Note that this part is RoHS non-compliant, which may impact regulatory requirements depending on application context.

Alternative with Enhanced Tolerance: ARR06B105JGS

ARR06B105JGS provides tighter tolerance specification (±5% vs. ±10%), offering improved capacitance accuracy. This part is suitable for applications requiring stricter capacitance control. RoHS non-compliance status requires evaluation against project requirements.

Low ESL Alternative: C062H105K5R5GA

C062H105K5R5GA is specified with low ESL characteristics and is designed for bypass and decoupling applications. This part maintains full electrical equivalence with ROHS3 compliance and active status. Physical dimensions are slightly reduced (0.290" L x 0.090" W), providing a compact alternative for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can ARR06B105KGS be used as a direct replacement for HT06BB105KN?

A: Yes. ARR06B105KGS is electrically and mechanically equivalent to HT06BB105KN. Both parts have identical capacitance (1 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 200°C), and lead spacing (0.200" / 5.08mm). The parts are pin-compatible and require no circuit modifications.

Q: What is the difference between the substitute parts listed?

A: Substitute parts differ in three primary aspects: (1) voltage rating—ARR07D105KGS provides 100V versus 50V for others; (2) tolerance—ARR06B105JGS offers ±5% versus ±10% for others; (3) physical dimensions—some parts have body widths of 0.100" versus 0.150", and C062H105K5R5GA has reduced overall dimensions; (4) compliance certifications—some parts are ROHS3 compliant while others are RoHS non-compliant. All maintain identical capacitance, temperature coefficient, and operating temperature range.

Q: Does the physical size difference between substitute parts affect circuit board compatibility?

A: Physical dimensions affect board layout and component spacing. The original HT06BB105KN has dimensions of 0.300" L x 0.150" W. ARR06B105KGS, ARR06B105JGS, ARR06B105KWS, and ARR07B105KGS have dimensions of 0.300" L x 0.100" W, providing a narrower footprint. C062H105K5R5GA has dimensions of 0.290" L x 0.090" W. All parts maintain the same 0.200" lead spacing and 0.300" seated height, ensuring through-hole compatibility. Verify board layout accommodates the selected part's body width.

Q: Should I select the 100V rated ARR07D105KGS instead of the 50V rated alternatives?

A: Selection depends on circuit voltage requirements and design margins. ARR07D105KGS provides increased voltage headroom and is suitable for applications where circuit conditions may approach or exceed 50V. However, the original design specified 50V rating, indicating adequate margin at that voltage level. ARR07D105KGS is RoHS non-compliant, which may conflict with project regulatory requirements. Use the 100V option only when circuit analysis confirms the need for additional voltage margin.

Q: What is the significance of RoHS compliance status in the substitute parts?

A: RoHS compliance status indicates regulatory conformance to hazardous substance restrictions. HT06BB105KN and recommended substitutes ARR06B105KGS, ARR07B105KGS, and C062H105K5R5GA are ROHS3 compliant. ARR07D105KGS, ARR06B105JGS, and ARR06B105KWS are RoHS non-compliant. Selection depends on application regulatory requirements. For applications subject to RoHS directives, select only ROHS3 compliant parts.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All substitute parts maintain the X7R temperature coefficient and -55°C to 200°C operating temperature range of the original HT06BB105KN. All parts are rated for identical thermal performance and are suitable for high-temperature applications within this range.

Q: What is the difference between ARR06B105KGS and ARR07B105KGS?

A: Both parts are electrically identical with 1 µF capacitance, ±10% tolerance, 50V rating, X7R temperature coefficient, and -55°C to 200°C operating range. Both are ROHS3 compliant and active in production. The primary difference is the base product number designation (ARR06B versus ARR07B), which reflects different product series within KEMET's industrial X7R line. Both are functionally equivalent for circuit applications.
