Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/1A3400-10 are identified based on compatibility within the 1AXXXX series and alignment of critical mechanical and electrical parameters. The primary substitution criteria include:

Mechanical Compatibility:

• Fuse size: 0.394" Dia (10mm)
• Mounting type: Through Hole
• Orientation: Horizontal
• Termination style: PC Pin
• Fuseholder type: Clip
• Number of circuits: 1

Electrical Compatibility:

• Series designation: 1AXXXX
• Fuse type: Cartridge
• For use with 13/32" Dia Fuses

The substitute part BK/1A3400-09-R maintains full mechanical compatibility and operates within the same product family. The primary difference is the current rating specification, which is a design parameter that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The BK/1A3400-09-R is available as an active product from Eaton - Electronics Division, addressing the obsolescence status of the BK/1A3400-10. Both parts maintain identical mechanical specifications and operate within the same product series.

Product Status Consideration: The BK/1A3400-09-R carries active product status with significantly higher inventory availability (16,109 pieces), compared to the obsolete BK/1A3400-10 (948 pieces).

Compliance Status: The BK/1A3400-09-R meets ROHS3 compliance and is REACH unaffected, providing enhanced regulatory alignment for new designs and procurement cycles.

Current Rating Differential: The substitute part is rated for 20 A operation, compared to the 30 A rating of the main part. This parameter difference requires evaluation against circuit protection requirements and application current specifications.

Frequently Asked Questions (FAQ)

Q: Can the BK/1A3400-09-R directly replace the BK/1A3400-10 in existing designs?

A: Mechanical and electrical compatibility is confirmed for the 1AXXXX series. The current rating difference (20 A versus 30 A) must be evaluated against application requirements. Both parts accommodate identical 10mm cartridge fuses, utilize horizontal orientation, and employ PC pin termination.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (30 A versus 20 A), product status (obsolete versus active), contact material (beryllium copper versus spring bronze), contact finish (silver versus tin), and RoHS certification level (RoHS Compliant versus ROHS3 Compliant).

Q: Are there packaging differences between the main part and substitute?

A: The BK/1A3400-10 is supplied without specified packaging designation. The BK/1A3400-09-R is packaged in bags. Packaging requirements should be confirmed with procurement specifications.

Q: Do both parts share the same fuse compatibility?

A: Yes. Both the BK/1A3400-10 and BK/1A3400-09-R are designed for use with 13/32" diameter fuses and accommodate 0.394" (10mm) diameter cartridge fuses.

Q: What is the moisture sensitivity rating for these components?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
