LR1F402R Equivalent & Substitute Parts

Part Overview

The LR1F402R is a 402 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 classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met for applications requiring alternative sourcing or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR1F402R are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match Exactly):

• Resistance value: 402 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 Requirements:

• RoHS3 compliance
• ECCN classification: EAR99
• HTSUS code: 8533.21.0090

The identified substitute parts MRS25000C4020FCT00 and MRS25000C4020FRP00 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 within acceptable tolerance for axial through-hole component placement in standard PCB designs.

Parameter Comparison

Engineering Selection Recommendations

All three resistor options—LR1F402R, MRS25000C4020FCT00, and MRS25000C4020FRP00—are Active product status components with full ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by packaging availability and inventory requirements rather than electrical performance differences.

The LR1F402R is supplied in Tape & Box packaging with 740 pieces in stock. The MRS25000C4020FCT00 is supplied in Cut Tape packaging with 1,267 pieces in stock. The MRS25000C4020FRP00 is supplied in Cut Tape packaging with 15,777 pieces in stock. Both Vishay substitute parts carry REACH Unaffected status, while the TE Connectivity part lists REACH status as Vendor Undefined.

Physical dimensions of the Vishay parts (0.098" Dia x 0.256" L) are marginally larger than the TE Connectivity part (0.091" Dia x 0.244" L), but both conform to standard axial resistor form factors and are compatible with conventional through-hole PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C4020FCT00 and MRS25000C4020FRP00 be used interchangeably with LR1F402R?

A: Yes. Both Vishay parts meet all electrical and mechanical specifications required for direct substitution. The primary difference is packaging format: MRS25000C4020FCT00 is supplied in Cut Tape, while MRS25000C4020FRP00 is also supplied in Cut Tape. The TE Connectivity LR1F402R is supplied in Tape & Box format.

Q: What is the difference between MRS25000C4020FCT00 and MRS25000C4020FRP00?

A: Both parts are identical in electrical specifications, composition, and physical dimensions. The difference lies in packaging and inventory availability. MRS25000C4020FRP00 has significantly higher stock levels (15,777 pieces versus 1,267 pieces).

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

A: No. The dimensional difference (0.098" Dia x 0.256" L for Vishay versus 0.091" Dia x 0.244" L for TE Connectivity) is within standard axial resistor tolerances and does not affect PCB hole sizing or component placement in conventional through-hole assembly.

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

A: All three parts are ROHS3 compliant and classified as EAR99 for export control purposes. Both Vishay parts carry REACH Unaffected status. The TE Connectivity part lists REACH status as Vendor Undefined.

Q: What packaging format should be selected for high-volume assembly?

A: MRS25000C4020FRP00 in Cut Tape format is suitable for automated tape-fed assembly equipment. MRS25000C4020FCT00 is also available in Cut Tape format. LR1F402R in Tape & Box format is suitable for manual or semi-automated assembly processes.
