LR1F22R1 Equivalent & Substitute Parts

Part Overview

The LR1F22R1 is a 22.1 Ohms ±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 Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F22R1 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 22.1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Compliance: ROHS3 compliant (exact match required)

The identified substitute parts MRS25000C2219FCT00 and MRS25000C2219FRP00 from Vishay Beyschlag/Draloric/BC Components meet all electrical specifications and compliance requirements. These parts differ only in packaging format (Cut Tape versus Tape & Reel) and physical dimensions within acceptable mechanical tolerances for axial resistor installation.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C2219FCT00 or MRS25000C2219FRP00 be used as direct replacements for LR1F22R1?

A: Yes. Both Vishay parts are electrically and mechanically equivalent to the TE Connectivity LR1F22R1. All three components share identical resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and compliance certifications.

Q: What is the difference between MRS25000C2219FCT00 and MRS25000C2219FRP00?

A: Both parts are electrically identical. The difference is packaging format: MRS25000C2219FCT00 is supplied in Cut Tape (CT) format, while MRS25000C2219FRP00 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly lines, while Cut Tape is suitable for lower-volume or manual assembly processes.

Q: Are there physical dimension differences between these parts?

A: The LR1F22R1 has dimensions of 0.091" Dia x 0.244" L (2.30mm x 6.20mm). The Vishay MRS25 series parts have dimensions of 0.098" Dia x 0.256" L (2.50mm x 6.50mm). These dimensional variations are within acceptable mechanical tolerances for axial resistor installation on standard PCB layouts and do not affect electrical performance or circuit compatibility.

Q: Do all three parts meet the same compliance standards?

A: Yes. LR1F22R1, MRS25000C2219FCT00, and MRS25000C2219FRP00 are all ROHS3 compliant, classified under ECCN EAR99, and share the same HTSUS code 8533.21.0090. Moisture sensitivity is not applicable to any of these parts.

Q: Which part should be selected for high-volume production?

A: MRS25000C2219FRP00 is recommended for high-volume production due to Tape & Reel packaging compatibility with automated assembly equipment and the highest available inventory (14460 pieces).

Q: Are there any temperature performance differences between these parts?

A: No. All three parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C, ensuring equivalent thermal performance in all applications.
