Substitute Part Grouping Explanation

Substitution eligibility for the MF-RHT1300-0 is determined by the following critical parameters:

Voltage rating must equal or exceed 16V maximum
Current hold (Ih) rating must equal 13A
Mounting type must be through-hole radial disc configuration
Operating temperature range must encompass -40°C to 125°C
RoHS3 compliance is required

The identified substitute parts meet these core electrical and mechanical criteria, enabling direct functional replacement in circuit applications designed for the MF-RHT1300-0.

Engineering Selection Recommendations

Both RHEF1300 and AHRF1300 are qualified substitutes for the MF-RHT1300-0 based on matching voltage, hold current, and operating temperature specifications. All three parts maintain ROHS3 compliance and active product status.

RHEF1300 provides the closest electrical match with identical current trip (24A) and time to trip (13s) characteristics, along with matching initial resistance (4.1 mOhms). This part carries additional agency approvals including CSA, TUV, and UL certifications.

AHRF1300 meets all core substitution criteria with slightly different trip characteristics (27A trip current, 15s time to trip) and lower initial resistance (3.4 mOhms). Lead spacing differs at 0.400" compared to the MF-RHT1300-0 at 0.215", requiring PCB layout verification for through-hole pad compatibility.

Frequently Asked Questions (FAQ)

Q: Can RHEF1300 and AHRF1300 be used interchangeably with MF-RHT1300-0?

A: Both parts meet the core electrical requirements (16V, 13A hold current, -40°C to 125°C operation). However, lead spacing differences must be verified against PCB design. RHEF1300 maintains identical lead spacing (0.215") to the original part, while AHRF1300 uses 0.400" spacing.

Q: What is the significance of the different trip current values?

A: MF-RHT1300-0 and RHEF1300 both trip at 24A, while AHRF1300 trips at 27A. This 3A difference affects the overcurrent threshold. Selection depends on circuit protection requirements and whether the higher trip point is acceptable for the application.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: What certifications should I consider for my application?

A: MF-RHT1300-0 carries AEC-Q200 rating. RHEF1300 includes CSA, TUV, and UL approvals in addition to AEC-Q200 compliance. Application requirements and regional standards should guide certification selection.

Q: How do initial resistance values affect circuit performance?

A: MF-RHT1300-0 and RHEF1300 both specify 4.1 mOhms minimum initial resistance, while AHRF1300 specifies 3.4 mOhms. Lower resistance reduces voltage drop across the fuse during normal operation. All three maintain identical post-trip resistance (10 mOhms maximum).
