Substitute Part Grouping Explanation

Substitution for the 16R090BPR is determined by strict equivalence across the following critical parameters:

• Voltage rating: 16V maximum
• Hold current: 900 mA
• Trip current: 1.8 A
• Maximum current: 40 A
• Time to trip: 1.2 s
• Initial resistance: 70 mOhms minimum
• Post-trip resistance: 180 mOhms maximum
• Operating temperature range: -40°C to 85°C
• Mounting configuration: Through hole radial disc package
• Component type: Polymeric PTC resettable fuse

The identified substitute parts maintain identical electrical performance characteristics and mechanical form factors within acceptable dimensional tolerances. Packaging format differences (cut tape versus tape & reel) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

RUSBF090-2 (Littelfuse) is the primary substitute for 16R090BPR. This part maintains active product status with higher inventory availability (7893 pcs) compared to the obsolete original. Both components are manufactured by Littelfuse within the same product family (PolySwitch® and POLY-FUSE® series respectively), ensuring design continuity. Certifications include CSA, TUV, and UL approval, with ROHS3 compliance and REACH unaffected status.

PTR016V0090-TR (Eaton - Electronics Division) serves as an alternative substitute with active product status. This part is certified by TUV and maintains ROHS3 compliance. The Eaton component provides cross-manufacturer equivalence with identical electrical specifications and mechanical compatibility.

Both substitute parts are suitable for direct replacement in applications currently using 16R090BPR, with no circuit redesign required.

Frequently Asked Questions (FAQ)

Q: Can RUSBF090-2 directly replace 16R090BPR in existing designs?

A: Yes. RUSBF090-2 maintains identical electrical parameters (16V, 900 mA hold current, 1.8 A trip current, 1.2 s trip time) and mechanical form factor (through hole radial disc package). The parts are functionally equivalent.

Q: What is the difference between the packaging formats listed?

A: 16R090BPR uses standard packaging format, RUSBF090-2 is supplied in cut tape (CT), and PTR016V0090-TR is supplied in tape & reel (TR). These differences affect procurement and assembly processes but do not impact component performance or compatibility.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. Lead spacing differs slightly: 16R090BPR at 0.201" (5.10mm), RUSBF090-2 at 0.199" (5.05mm), and PTR016V0090-TR at 0.197" (5.00mm). Width dimensions vary marginally: 16R090BPR at 0.118" (3.00mm) versus 0.122" (3.10mm) for both substitutes. These variations remain within standard PCB pad tolerances for through-hole radial components.

Q: Which substitute offers better long-term availability?

A: RUSBF090-2 carries active product status with significantly higher inventory levels (7893 pcs), making it the preferred choice for new designs and long-term production support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts (16R090BPR, RUSBF090-2, and PTR016V0090-TR) are ROHS3 compliant.
