BK60-160-DZ Equivalent & Substitute Parts

Part Overview

The BK60-160-DZ is a polymeric PTC resettable fuse manufactured by YAGEO, designed for through-hole radial mounting in disc configuration. This component operates at 60V maximum voltage with a 1.6 A hold current rating and provides automatic overcurrent protection through thermal response characteristics. The part is currently in active production status with 905 units available in inventory.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and thermal characteristics align with the original specification. Alternative sources provide equivalent functionality for applications requiring component availability, supply chain flexibility, or specific certification requirements.

All identified substitute parts meet these criteria across all specified parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BK60-160-DZ (YAGEO), 0ZRR0160FF1A (Bel Fuse Inc.), and RS60RB-160 (OptiFuse)—are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability, certification requirements, and supply chain considerations.

Certification Profile:

The BK60-160-DZ carries UL approval. The 0ZRR0160FF1A provides expanded certifications including cURus, TUV, and UL, with additional compliance statements including AEC-Q200 rating and ROHS3 compliance. The RS60RB-160 carries cUL, TUV, and UL approvals with ROHS3 compliance.

Inventory Availability:

Current stock levels are: BK60-160-DZ (905 units), 0ZRR0160FF1A (1450 units), and RS60RB-160 (3525 units).

Compliance Considerations:

Applications requiring automotive-grade qualification should reference the AEC-Q200 rating available with the 0ZRR0160FF1A. Applications with RoHS compliance requirements are satisfied by both 0ZRR0160FF1A and RS60RB-160, which carry explicit ROHS3 compliance statements.

Frequently Asked Questions (FAQ)

Q: Can the 0ZRR0160FF1A or RS60RB-160 be used as direct replacements for the BK60-160-DZ?

A: Yes. All three parts share identical electrical parameters (60V maximum voltage, 1.6 A hold current, 3.2 A trip current, 11.4 s time to trip, 90 mOhms initial resistance, 220 mOhms post-trip resistance), identical mechanical dimensions (0.642" diameter x 0.122" thickness, 0.839" seated height, 0.201" lead spacing), and identical mounting configuration (through-hole radial disc). Direct substitution is supported at the circuit board level.

Q: Are there differences in certification or compliance between these parts?

A: The BK60-160-DZ carries UL approval. The 0ZRR0160FF1A carries cURus, TUV, and UL approvals with AEC-Q200 automotive qualification and ROHS3 compliance. The RS60RB-160 carries cUL, TUV, and UL approvals with ROHS3 compliance. Applications with specific certification requirements should select accordingly.

Q: Do these parts have identical thermal characteristics?

A: Yes. All three parts operate across the identical temperature range of -40°C to 85°C and share identical time-to-trip specifications of 11.4 seconds.

Q: Are the physical dimensions identical for PCB layout purposes?

A: Yes. All three parts have identical dimensions: 0.642" diameter x 0.122" thickness (16.30mm x 3.10mm), 0.839" seated height (21.30mm), and 0.201" lead spacing (5.10mm). PCB layouts designed for one part accommodate all three without modification.

Q: Which part should be selected for highest inventory availability?

A: The RS60RB-160 (OptiFuse) currently has the highest inventory level at 3525 units, followed by the 0ZRR0160FF1A (Bel Fuse Inc.) at 1450 units, and the BK60-160-DZ (YAGEO) at 905 units.

Q: Are there differences in moisture sensitivity between these parts?

A: The BK60-160-DZ and RS60RB-160 both carry MSL 1 (Unlimited) rating. The 0ZRR0160FF1A carries Not Applicable moisture sensitivity designation.
