Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT08BB105KN is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 1 µF
• Temperature coefficient: X7R
• Operating temperature range: -55°C ~ 200°C
• Mounting type: Through Hole Radial
• Lead spacing: 0.400" (10.16mm)

Allowable Variation Parameters:

• Voltage rating: May be equal to or greater than 50V
• Tolerance: May be tighter than ±10%
• Physical dimensions: Minor variations acceptable if lead spacing and mounting type remain constant

The ARR08D105JGS meets all mandatory matching criteria while providing enhanced voltage rating (100V) and improved tolerance (±5%), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The ARR08D105JGS is the direct equivalent substitute for the HT08BB105KN based on the following engineering criteria:

Electrical Compatibility: The substitute maintains identical capacitance (1 µF) and temperature coefficient (X7R) with matching operating temperature range (-55°C ~ 200°C). The 100V voltage rating of the substitute exceeds the original 50V specification, providing additional design margin without functional compromise.

Physical Compatibility: Lead spacing (0.400"), mounting type (Through Hole Radial), and package configuration are identical, ensuring direct PCB footprint compatibility.

Product Status: The ARR08D105JGS is listed as Active, ensuring continued availability and supply chain reliability. The original HT08BB105KN is obsolete, making substitution necessary for ongoing production and field replacements.

Compliance: The ARR08D105JGS is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications.

Frequently Asked Questions (FAQ)

Q: Can the ARR08D105JGS be used as a direct replacement for HT08BB105KN in existing designs?

A: Yes. The substitute maintains identical capacitance, temperature coefficient, operating temperature range, lead spacing, and mounting type. The higher voltage rating (100V vs. 50V) and tighter tolerance (±5% vs. ±10%) present no compatibility issues and provide improved performance margins.

Q: What is the significance of the higher 100V voltage rating on the substitute part?

A: The ARR08D105JGS is rated for 100V operation, compared to the original 50V rating. This higher voltage specification provides additional design margin and does not affect circuit operation when used in applications originally specified for 50V.

Q: Are the physical dimensions compatible for PCB assembly?

A: Yes. Both parts are Through Hole Radial packages with identical lead spacing (0.400" / 10.16mm). The ARR08D105JGS has a smaller width dimension (0.100" vs. 0.270"), which presents no assembly or compatibility issues.

Q: What is the difference in tolerance between these parts?

A: The HT08BB105KN has ±10% tolerance, while the ARR08D105JGS has ±5% tolerance. The tighter tolerance of the substitute provides improved capacitance accuracy without affecting circuit compatibility.

Q: Is the ARR08D105JGS available in the same packaging format?

A: The ARR08D105JGS is supplied in Bulk packaging, compared to the original part's standard packaging. Both are identical Through Hole Radial components suitable for the same PCB assembly processes.
