LR1F13K Equivalent & Substitute Parts

Part Overview

The LR1F13K is a 13 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 RoHS3 compliant and classified as Active product status. Substitute parts are necessary when the primary part is unavailable from inventory, when alternative packaging formats are required, or when sourcing from multiple manufacturers is required for supply chain resilience.

Substitute Part Grouping Explanation

Substitution of the LR1F13K is permissible with parts that maintain identical electrical specifications across all critical parameters. The following parameters determine substitution eligibility:

Resistance value: 13 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.6W (exact match required)
Composition: Metal Film (exact match required)
Package type: Axial (exact match required)
Temperature coefficient: ±50ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)

All substitute parts listed below meet these criteria. Packaging format (Tape & Box versus Cut Tape) represents a logistical difference and does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All three Vishay Beyschlag/Draloric/BC Components substitute parts (MRS25000C1302FC100, MRS25000C1302FCT00, and MRS25000C1302FRP00) are electrically and mechanically equivalent to the LR1F13K. Each part maintains Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component.

Selection among the three Vishay alternatives is determined by packaging and inventory requirements:

MRS25000C1302FC100: Cut Tape packaging, 1655 units in stock
MRS25000C1302FCT00: Cut Tape packaging, 5308 units in stock
MRS25000C1302FRP00: Cut Tape packaging, 12010 units in stock

The MRS25000C1302FRP00 variant offers the highest inventory availability. All three variants are functionally interchangeable with the original LR1F13K and with each other.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C1302FC100, MRS25000C1302FCT00, and MRS25000C1302FRP00 be used interchangeably with LR1F13K?

A: Yes. All three Vishay parts are direct electrical and mechanical equivalents. They share identical resistance (13 kOhms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), and package type (Axial). All are RoHS3 compliant and Active status.

Q: What is the difference between the three Vishay substitute parts?

A: The three Vishay parts are electrically identical. Differences exist only in packaging designation and inventory levels. All three use Cut Tape packaging. MRS25000C1302FRP00 has the highest inventory availability at 12010 units.

Q: Are there dimensional differences between LR1F13K and the Vishay substitutes?

A: Minor dimensional variations exist. The LR1F13K measures 0.091" Dia x 0.244" L (2.30mm x 6.20mm). The Vishay MRS25 series measures 0.098" Dia x 0.256" L (2.50mm x 6.50mm). These differences do not affect electrical performance or standard PCB mounting applications.

Q: Does packaging format (Tape & Box versus Cut Tape) affect component performance?

A: No. Packaging format is a logistical consideration only. It does not affect electrical characteristics, mechanical compatibility, or performance in circuit applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The LR1F13K and all three Vishay substitute parts are RoHS3 compliant.

Q: Can these parts be used in applications requiring -55°C to 155°C operation?

A: Yes. All parts, including the original LR1F13K and all three Vishay substitutes, are rated for -55°C to 155°C operation.
