Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F36K5 is determined by equivalence across the following critical parameters:

• Resistance Value: 36.5 kOhms (exact match required)
• Tolerance: ±1% (precision specification must be maintained)
• Power Rating: 0.6W (thermal dissipation capability)
• Composition: Metal Film (electrical performance characteristics)
• Temperature Coefficient: ±50ppm/°C (stability specification)
• Operating Temperature Range: -55°C ~ 155°C (environmental limits)
• Package Type: Axial (mechanical form factor and PCB compatibility)
• Terminations: 2 (connection configuration)
• Compliance: RoHS3 Compliant (regulatory requirement)

The substitute part MRS25000C3652FCT00 meets all critical electrical and mechanical parameters, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F36K5 and MRS25000C3652FCT00 are Active status products with full RoHS3 compliance. The parts are electrically equivalent across all specified parameters including resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

Physical dimensions differ slightly between the two parts. The LR1F36K5 measures 0.091" diameter by 0.244" length, while the MRS25000C3652FCT00 measures 0.098" diameter by 0.256" length. These dimensional variations are within typical axial resistor manufacturing tolerances and do not affect electrical performance or standard PCB footprint compatibility for through-hole applications.

Packaging format differs: the LR1F36K5 is supplied in Tape & Box format, while the MRS25000C3652FCT00 is supplied in Cut Tape format. Selection between these parts should consider procurement volume requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C3652FCT00 be used as a direct replacement for LR1F36K5?

A: Yes. Both parts are electrically identical with matching resistance value (36.5 kOhms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are metal film axial resistors with two terminations and RoHS3 compliance.

Q: Are there physical size differences between these parts?

A: Yes. The LR1F36K5 has a diameter of 0.091" and length of 0.244", while the MRS25000C3652FCT00 has a diameter of 0.098" and length of 0.256". These differences are minor and do not affect standard through-hole PCB footprint compatibility.

Q: Do packaging format differences affect substitution?

A: Packaging format (Tape & Box versus Cut Tape) affects procurement and handling but does not impact electrical or mechanical performance. Selection should be based on production volume and inventory requirements.

Q: Are both parts RoHS3 compliant?
