LR1F3K01 Equivalent & Substitute Parts

Part Overview

The LR1F3K01 is a 3.01 kOhms ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C. The component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR1F3K01 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 3.01 kOhms
• Tolerance: ±1%
• Power rating: 0.6W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Compatibility Criteria:

• Package type: Axial
• Number of terminations: 2
• Physical form factor: Through-hole

All substitute parts listed meet these criteria and are manufactured by Vishay Beyschlag/Draloric/BC Components in the MRS25 series. Both substitute parts maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both MRS25000C3011FRP00 and MRS25000C3011FCT00 are direct electrical and functional equivalents to the LR1F3K01. Selection between these options is determined by packaging requirements and inventory availability.

MRS25000C3011FRP00 (Vishay Beyschlag/Draloric/BC Components):

• Packaging: Cut Tape (CT)
• Inventory: 13,368 Pcs New Original In Stock
• REACH Status: REACH Unaffected
• Suitable for high-volume production environments requiring tape packaging

MRS25000C3011FCT00 (Vishay Beyschlag/Draloric/BC Components):

• Packaging: Cut Tape (CT)
• Inventory: 2,403 Pcs New Original In Stock
• REACH Status: REACH Unaffected
• Suitable for applications requiring cut tape format

Both substitute parts maintain identical electrical specifications, temperature performance, and regulatory compliance (ROHS3, EAR99 classification, HTSUS 8533.21.0090). Physical dimensions differ slightly between the TE Connectivity LR1F3K01 and Vishay MRS25 series components; verification of board layout clearances is necessary when substituting in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Are the MRS25000C3011FRP00 and MRS25000C3011FCT00 electrically identical to the LR1F3K01?

A: Yes. Both Vishay parts match the LR1F3K01 in resistance value (3.01 kOhms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). Metal film composition and axial package type are identical across all three parts.

Q: What is the difference between MRS25000C3011FRP00 and MRS25000C3011FCT00?

A: Both parts are electrically equivalent. The difference is in packaging format: MRS25000C3011FRP00 is supplied in Cut Tape (CT) with 13,368 units in stock, while MRS25000C3011FCT00 is also Cut Tape (CT) with 2,403 units in stock. Selection depends on procurement volume and packaging requirements.

Q: Do the physical dimensions differ between the LR1F3K01 and substitute parts?

A: Yes. The LR1F3K01 measures 0.091" Dia x 0.244" L (2.30mm x 6.20mm), while both Vishay MRS25 substitutes measure 0.098" Dia x 0.256" L (2.50mm x 6.50mm). These dimensional differences must be evaluated for board layout compatibility, particularly in space-constrained designs.

Q: Are all three parts RoHS compliant?

A: Yes. The LR1F3K01, MRS25000C3011FRP00, and MRS25000C3011FCT00 are all ROHS3 compliant. Both Vishay parts carry REACH Unaffected status.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical substitution is direct. Mechanical substitution requires verification of physical dimensions and board layout clearances due to the size differences noted above. All three parts are classified as Active products with identical regulatory compliance.
