Substitute Part Grouping Explanation

Substitution of the LR1F165R is permissible with parts that maintain identical electrical specifications across all critical parameters. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match Exactly):

• Resistance value: 165 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 Exactly):

• Package type: Axial
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant

The MRS25000C1650FRP00 manufactured by Vishay Beyschlag/Draloric/BC Components satisfies all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F165R and MRS25000C1650FRP00 are active production components with ROHS3 compliance certification. Selection between these parts is based on the following factors:

LR1F165R (TE Connectivity):

• Supplied in Tape & Box packaging format
• Smaller physical dimensions (0.091" diameter × 0.244" length)
• Current inventory: 859 pieces

MRS25000C1650FRP00 (Vishay):

• Supplied in Tape & Reel packaging format
• Slightly larger physical dimensions (0.098" diameter × 0.256" length)
• Current inventory: 7771 pieces

Both parts are electrically and functionally equivalent. Component selection should be based on packaging requirements, available inventory levels, and procurement lead times. Physical dimension differences are within acceptable tolerances for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C1650FRP00 be used as a direct replacement for LR1F165R in existing designs?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The minor physical dimension differences (0.007" diameter and 0.012" length) are functionally compatible in standard through-hole PCB layouts.

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

A: Tape & Box (TB) packaging supplies components in tape format within a protective box, suitable for smaller quantity orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both LR1F165R and MRS25000C1650FRP00 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: Do the physical dimension differences affect PCB layout compatibility?

A: The dimension differences are minimal and within standard tolerances for axial through-hole resistor footprints. Both parts use identical 2-termination axial package configuration and are compatible with standard PCB hole spacing.

Q: What is the temperature coefficient specification and why is it important?

A: Both parts have a temperature coefficient of ±50ppm/°C, meaning the resistance value changes by a maximum of 50 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision applications requiring stable resistance values across the operating temperature range of -55°C to 155°C.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that packaging format requirements are compatible with your assembly process. If your production line is configured for Tape & Reel format, the MRS25000C1650FRP00 is the appropriate selection. If Tape & Box format is required, the LR1F165R is the appropriate selection.
