Engineering Selection Recommendations

Both ACR05B103KGS and ACR06B103KGS are direct functional replacements for the obsolete HT55BN103KN. Selection between the two substitute parts should be based on the following factors:

Product Status: Both substitute parts are in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete HT55BN103KN.

Compliance Considerations: Both substitute parts carry identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications as the original part. Both are RoHS non-compliant and REACH Affected, maintaining regulatory alignment with the original component.

Inventory Availability: ACR06B103KGS currently has 891 pieces in stock, while ACR05B103KGS has 792 pieces available. Selection may be influenced by immediate procurement requirements.

Series Designation: Both substitutes belong to the ACR Industrial C0G HT200C series, which is the active equivalent to the obsolete HTHP LDD Industrial C0G HT200C series of the original part.

Frequently Asked Questions (FAQ)

Q: Can ACR05B103KGS and ACR06B103KGS be used interchangeably with HT55BN103KN?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (10000 pF, ±10%, 50V, C0G/NP0) and mechanical dimensions (0.200" lead spacing, radial through-hole package). Direct substitution on the circuit board is possible without design modification.

Q: What is the difference between ACR05B103KGS and ACR06B103KGS?

A: Both parts are electrically and mechanically identical. The difference in base product numbers (ACR05B versus ACR06B) reflects internal KEMET manufacturing or series designation but does not affect functional performance or compatibility.

Q: Are there any compliance differences between the substitute parts and the original HT55BN103KN?

A: No. All three parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications. Both substitutes are RoHS non-compliant and REACH Affected, matching the regulatory profile of the original component.

Q: Why is HT55BN103KN obsolete?

A: The HT55BN103KN has been discontinued by KEMET. The ACR series (ACR05B103KGS and ACR06B103KGS) represents the active product line continuation with equivalent specifications.

Q: Will the substitute parts fit the same PCB footprint as HT55BN103KN?

A: Yes. All three parts have identical lead spacing (0.200" / 5.08mm), physical dimensions (0.200" L x 0.100" W), and radial through-hole package configuration. No PCB layout modification is required.

Q: Are the operating temperature ranges identical?

A: Yes. All three parts operate across the same temperature range of -55°C to 200°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across the full operating envelope.
