LR1F33R2 Equivalent & Substitute Parts

Part Overview

The LR1F33R2 is a 33.2 Ohm ±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 and is classified as an active product with ROHS3 compliance. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F33R2 is determined by strict equivalence across the following parameters:

  • Resistance Value: 33.2 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)
  • Termination Count: 2 (exact match required)
  • Regulatory Compliance: ROHS3 Compliant (exact match required)

The substitute part MRS25000C3329FRP00 manufactured by Vishay Beyschlag/Draloric/BC Components meets all electrical and mechanical criteria for direct substitution. Physical dimensions vary slightly within acceptable tolerances for axial resistor form factors.

Engineering Selection Recommendations

Both the LR1F33R2 and MRS25000C3329FRP00 are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts is based on availability and packaging format:

  • LR1F33R2: Supplied in Tape & Box (TB) packaging with 947 units in stock
  • MRS25000C3329FRP00: Supplied in Cut Tape (CT) packaging with 1594 units in stock

The MRS25000C3329FRP00 exhibits marginally larger physical dimensions (0.098" diameter × 0.256" length versus 0.091" diameter × 0.244" length). These dimensional differences remain within standard tolerances for axial resistor mounting on printed circuit boards and do not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C3329FRP00 be used as a direct replacement for LR1F33R2?

A: Yes. Both parts share identical electrical specifications: 33.2 Ohms ±1% tolerance, 0.6W power rating, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are metal film axial resistors with ROHS3 compliance.

Q: Are there physical compatibility concerns with the dimensional differences?

A: No. The LR1F33R2 measures 0.091" diameter × 0.244" length, while the MRS25000C3329FRP00 measures 0.098" diameter × 0.256" length. These variations are within standard tolerances for axial through-hole resistor mounting and do not affect PCB layout or thermal performance.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging supplies components on tape wound in a box, suitable for automated assembly in larger quantities. Cut Tape (CT) packaging supplies components on tape cut to specific lengths, suitable for smaller batch orders or manual assembly. Both formats contain identical components.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both LR1F33R2 and MRS25000C3329FRP00 are ROHS3 compliant and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0090).

Q: Can either part be used in high-temperature applications?

A: Yes. Both parts operate across the full temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C, making them suitable for industrial and automotive applications requiring extended temperature performance.
