Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HTB-22I-R are classified based on the following substitution criteria:

Direct Equivalent (Packaging Variant): The part BK/HTB-22I-R is a direct functional equivalent differing only in packaging format (Box vs. Bulk). This part maintains identical electrical specifications: 20 A, 250V, 1 circuit, cartridge fuse type, and panel mount configuration. The fuse size, termination style (Quick Connect - 0.187"), and mounting compatibility remain unchanged. This substitution is valid for applications where packaging format does not impose constraints.

Similar Part (Electrical Downgrade): The part BK16-HTJ-601I is classified as a similar part rather than a direct substitute due to a reduced current rating of 10 A versus the 20 A rating of HTB-22I-R. While both parts share common parameters (250V voltage rating, 1 circuit, cartridge fuse type, panel mount configuration, 0.25" fuse diameter), the current rating difference represents a functional limitation. This part is suitable only for applications requiring 10 A or lower current protection. Additional differences include termination style (Solder Lug vs. Quick Connect) and contact material specifications (Copper Alloy with Nickel finish vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (HTB-22I-R ↔ BK/HTB-22I-R): The BK/HTB-22I-R is a valid direct substitute when packaging format flexibility is acceptable. Both parts are manufactured by Eaton - Electronics Division, maintain identical electrical and mechanical specifications (20 A, 250V, 1 circuit, Quick Connect termination), and are both active products. The BK/HTB-22I-R carries ROHS3 compliance versus RoHS compliance for the HTB-22I-R, representing an enhanced compliance status. Inventory availability is significantly higher for BK/HTB-22I-R (5840 units vs. 894 units), supporting supply chain continuity.

For Similar Part Consideration (HTB-22I-R vs. BK16-HTJ-601I): The BK16-HTJ-601I is not a direct substitute due to the 10 A current rating limitation. This part is applicable only in circuit designs where the maximum required current protection is 10 A or lower. The reduced current rating represents a functional constraint that must be evaluated against circuit requirements. The termination style difference (Solder Lug vs. Quick Connect) introduces additional installation methodology changes. Selection of BK16-HTJ-601I requires explicit verification that the 10 A rating satisfies the application's protective requirements.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-22I-R replace HTB-22I-R in all applications?

A: Yes. BK/HTB-22I-R is a direct functional equivalent with identical electrical specifications (20 A, 250V), mechanical dimensions (0.25" x 1.26" fuse size), and termination style (Quick Connect - 0.187"). The only difference is packaging format (Box vs. Bulk). Both parts are active products from Eaton - Electronics Division.

Q: What is the primary limitation of BK16-HTJ-601I as a substitute?

A: The current rating of BK16-HTJ-601I is 10 A, compared to 20 A for HTB-22I-R. This represents a 50% reduction in current capacity. BK16-HTJ-601I is suitable only for applications requiring 10 A or lower circuit protection. Additionally, the termination style differs (Solder Lug vs. Quick Connect - 0.187"), requiring different installation methods.

Q: Are all substitute parts RoHS compliant?

A: Yes. HTB-22I-R is RoHS Compliant, BK/HTB-22I-R is ROHS3 Compliant, and BK16-HTJ-601I is RoHS Compliant. All parts meet RoHS requirements. ROHS3 represents an enhanced compliance designation.

Q: What is the fuse size compatibility for these parts?

A: HTB-22I-R and BK/HTB-22I-R both accommodate 0.25" diameter x 1.26" length (6.35mm x 32mm) cartridge fuses, specifically 3AG and 1/4" x 1-1/4" (SFE-20) fuse types. BK16-HTJ-601I accommodates 0.250" diameter (6.35mm) cartridge fuses, with length specifications not provided in available data.

Q: How do inventory levels compare?

A: HTB-22I-R has 894 units in stock (Bulk packaging). BK/HTB-22I-R has 5840 units in stock (Box packaging), providing significantly higher availability. BK16-HTJ-601I has 1794 units in stock (Bulk packaging).

Q: Are all parts single-circuit fuse holders?

A: Yes. HTB-22I-R, BK/HTB-22I-R, and BK16-HTJ-601I are all single-circuit (1 circuit) cartridge fuse holders rated for panel mount applications.
