Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the BK/S-8202-1 is determined by strict alignment of electrical and mechanical parameters. The primary substitute, BK/S-8202-1-R, maintains identical specifications across all critical dimensions: 30 A current rating, 600V voltage rating, chassis mount configuration, single circuit design, cartridge fuse type, 0.25" x 1.26" fuse size, and Quick Connect termination. The only variation is the contact finish specification (Tin-Lead versus Tin) and compliance certification update (RoHS3 Compliant with REACH Unaffected status). This part is classified as a Direct Manufacturer substitute and is fully interchangeable.

The secondary substitute, BK2-S-4202-1-R, is classified as a Similar part and operates under different electrical constraints. This part belongs to the S-4000 series and features a reduced current rating of 25 A at 250V, compared to the 30 A at 600V specification of the main part. Additionally, BK2-S-4202-1-R uses Through Hole mounting with PC Pin termination, whereas the main part uses Chassis Mount with Quick Connect termination. These differences indicate that BK2-S-4202-1-R is not a direct substitute but rather a related component for applications with lower voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (BK/S-8202-1-R):

The BK/S-8202-1-R is the appropriate direct substitute for the BK/S-8202-1. Both parts maintain identical electrical ratings (30 A, 600V), mechanical dimensions, mounting configuration, and termination style. The contact finish difference (Tin-Lead to Tin) does not affect functional compatibility. The BK/S-8202-1-R carries RoHS3 Compliant certification with REACH Unaffected status, representing an updated compliance profile. Both parts are Active status products with unlimited moisture sensitivity tolerance. Selection between these two parts is driven by compliance requirements and inventory availability rather than functional differences.

For Alternative Applications (BK2-S-4202-1-R):

The BK2-S-4202-1-R is not suitable as a direct substitute for the BK/S-8202-1 due to fundamental electrical and mechanical differences. This part operates at 250V with a 25 A rating, compared to the 600V and 30 A specifications of the main part. The mounting method differs (Through Hole versus Chassis Mount), and termination uses PC Pin instead of Quick Connect. The contact material is Copper Alloy rather than Spring Bronze. Selection of BK2-S-4202-1-R is appropriate only for applications with lower voltage and current requirements and compatible board-level mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can BK/S-8202-1-R be used as a direct replacement for BK/S-8202-1 in existing designs?

A: Yes. The BK/S-8202-1-R maintains identical electrical ratings (30 A, 600V), fuse size (0.25" x 1.26"), mounting type (Chassis Mount), and termination style (Quick Connect - 0.250"). The contact finish change from Tin-Lead to Tin does not affect electrical performance or mechanical compatibility. Both parts are Active status products manufactured by Eaton - Electronics Division.

Q: What are the key differences between BK/S-8202-1 and BK2-S-4202-1-R?

A: These parts differ in multiple critical parameters. BK2-S-4202-1-R operates at 250V with 25 A rating, whereas BK/S-8202-1 is rated for 600V at 30 A. BK2-S-4202-1-R uses Through Hole mounting with PC Pin termination, while BK/S-8202-1 uses Chassis Mount with Quick Connect termination. Contact material also differs: Copper Alloy versus Spring Bronze. These differences make BK2-S-4202-1-R unsuitable for applications requiring 600V and 30 A specifications.

Q: Are there compliance differences between BK/S-8202-1 and BK/S-8202-1-R?

A: BK/S-8202-1 carries RoHS Compliant certification. BK/S-8202-1-R carries RoHS3 Compliant certification with REACH Unaffected status. Both parts meet regulatory requirements for their respective compliance frameworks. Selection between these parts should consider the specific compliance requirements of the end application.

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

A: All three parts in this comparison accommodate 3AG cartridge fuses with dimensions of 0.25" diameter by 1.26" length (6.35mm x 32mm). Fuse selection must match the current and voltage ratings of the specific fuse block being used.

Q: How do termination styles affect circuit board integration?

A: BK/S-8202-1 and BK/S-8202-1-R use Quick Connect - 0.250" (6.3mm) termination, suitable for chassis-level wiring harnesses and external connections. BK2-S-4202-1-R uses PC Pin termination, designed for direct insertion into printed circuit board holes. These termination differences determine whether a part is suitable for chassis-level or board-level integration.
