LR1F332R Equivalent & Substitute Parts

Part Overview

The LR1F332R is a 332 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 with a temperature coefficient of ±50ppm/°C. The component is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring environmental compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and composition.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR1F332R are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Resistance value: 332 Ohms
• Tolerance: ±1%
• Power rating: 0.6W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: Axial
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The identified substitute parts MRS25000C3320FCT00 and MRS25000C3320FRP00 from Vishay Beyschlag/Draloric/BC Components meet all electrical and mechanical requirements. Physical dimensions vary slightly (0.098" Dia x 0.256" L versus 0.091" Dia x 0.244" L), which is acceptable within standard axial resistor form factor tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both MRS25000C3320FCT00 and MRS25000C3320FRP00 are direct electrical and mechanical equivalents to the LR1F332R. Selection between these options is determined by packaging requirements:

MRS25000C3320FCT00 is supplied in Cut Tape (CT) packaging with 936 pieces in stock.

MRS25000C3320FRP00 is supplied in Cut Tape (CT) packaging with 15027 pieces in stock.

All three parts maintain identical electrical performance specifications and comply with ROHS3 and REACH requirements. The slight dimensional variation in axial length and diameter falls within acceptable tolerances for through-hole PCB assembly and does not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C3320FCT00 or MRS25000C3320FRP00 be used as direct replacements for LR1F332R?

A: Yes. Both Vishay parts are direct substitutes. They provide identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The axial package type and two-terminal configuration are identical.

Q: What is the difference between MRS25000C3320FCT00 and MRS25000C3320FRP00?

A: Both parts are electrically and mechanically identical. The difference is in packaging format (both Cut Tape) and inventory availability. MRS25000C3320FRP00 has significantly higher stock levels (15027 pieces versus 936 pieces).

Q: Are there dimensional compatibility concerns with the slightly larger axial dimensions of the Vishay parts?

A: No. The Vishay parts measure 0.098" diameter by 0.256" length compared to the TE part at 0.091" diameter by 0.244" length. These variations are within standard axial resistor form factor tolerances and do not affect PCB layout or assembly compatibility for through-hole applications.

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

A: Yes. LR1F332R, MRS25000C3320FCT00, and MRS25000C3320FRP00 are all ROHS3 compliant and REACH unaffected.

Q: What is the temperature coefficient specification, and is it identical across all three parts?

A: The temperature coefficient is ±50ppm/°C for all three parts, ensuring identical thermal stability across the operating range of -55°C to 155°C.
