Parameter Comparison

Engineering Selection Recommendations

The BK/HKP-BBHH-R is the direct active equivalent for the obsolete BK/HKP-BBHH. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part is classified as obsolete, while BK/HKP-BBHH-R maintains active product status, ensuring continued availability and manufacturer support.

Compliance and Certifications: Both parts are RoHS compliant. The substitute part carries ROHS3 compliance designation, representing current regulatory alignment. Both parts are classified under ECCN EAR99 and share identical HTSUS coding (8538.90.8180), confirming equivalent trade classification.

Electrical and Mechanical Equivalence: All critical parameters—voltage rating, current rating, fuse size, mounting configuration, and termination style—are identical between the main part and substitute. This ensures direct functional replacement without circuit redesign or panel layout modification.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

The BK/HKP-BBHH-R is suitable for direct substitution in all applications where the BK/HKP-BBHH was originally specified.

Frequently Asked Questions (FAQ)

Q: Can BK/HKP-BBHH-R be used as a direct replacement for BK/HKP-BBHH?

A: Yes. The BK/HKP-BBHH-R is electrically and mechanically equivalent to the BK/HKP-BBHH. Both parts share identical voltage rating (250V), current rating (15A), fuse size (0.25" Dia x 1.26" L), mounting type (Panel Mount), and termination style (Quick Connect - 0.250"). No circuit modifications or panel layout changes are required.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The BK/HKP-BBHH is obsolete, while the BK/HKP-BBHH-R is active. The substitute part also carries ROHS3 compliance, representing current regulatory standards. All functional and electrical specifications remain identical.

Q: Are there packaging differences between BK/HKP-BBHH and BK/HKP-BBHH-R?

A: The BK/HKP-BBHH-R is supplied in bulk packaging, whereas the main part packaging specification is not provided in the technical data. Packaging format does not affect electrical or mechanical compatibility.

Q: What fuse types are compatible with these fuse holders?

A: Both the BK/HKP-BBHH and BK/HKP-BBHH-R accommodate 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (6.35mm x 32mm). These are standard cartridge fuse sizes rated for 250V applications.

Q: Are moisture sensitivity considerations relevant for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These components do not require special moisture control during storage, handling, or installation.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both parts are RoHS compliant. The BK/HKP-BBHH-R carries ROHS3 compliance, representing the current regulatory requirement. Both parts are classified as REACH Unaffected or carry equivalent environmental compliance status.
