LR1F475R Equivalent & Substitute Parts

Part Overview

The LR1F475R is a 475 Ohm ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor is designed for general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status with 748 units available in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F475R is permissible with parts that maintain identical electrical specifications across all critical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 475 Ohms
• Tolerance: ±1%
• Power rating: 0.6W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Metal Film

Mechanical Parameters (Must Match):

• Package type: Axial
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS3 Compliant status

The MRS25000C4750FRP00 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 LR1F475R and MRS25000C4750FRP00 are active production components with ROHS3 compliance certification. Selection between these parts is based on the following factors:

LR1F475R (TE Connectivity):

• Supplied in Tape & Box packaging format
• Smaller physical dimensions (2.30mm diameter x 6.20mm length)
• Current inventory: 748 units

MRS25000C4750FRP00 (Vishay):

• Supplied in Tape & Reel packaging format
• Slightly larger physical dimensions (2.50mm diameter x 6.50mm length)
• Current inventory: 29,313 units

Both parts are electrically and functionally equivalent. Component selection should be determined by packaging requirements, available inventory levels, and board layout constraints related to physical dimensions.

Frequently Asked Questions (FAQ)

Q: Are the LR1F475R and MRS25000C4750FRP00 electrically interchangeable?

A: Yes. Both parts have identical resistance values (475 Ohms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). They are direct electrical equivalents.

Q: What are the physical dimension differences between these parts?

A: The LR1F475R has a diameter of 0.091" (2.30mm) and length of 0.244" (6.20mm). The MRS25000C4750FRP00 has a diameter of 0.098" (2.50mm) and length of 0.256" (6.50mm). The MRS25000C4750FRP00 is slightly larger in both dimensions.

Q: Do the packaging format differences affect component functionality?

A: No. The LR1F475R is supplied in Tape & Box format while the MRS25000C4750FRP00 is supplied in Tape & Reel format. Both packaging formats contain identical components. Packaging format selection is based on manufacturing process requirements and inventory handling procedures.

Q: Are both parts RoHS compliant?

A: Yes. Both the LR1F475R and MRS25000C4750FRP00 are ROHS3 compliant.

Q: Can the MRS25000C4750FRP00 be used as a direct replacement in existing designs specified for the LR1F475R?

A: Yes, provided that the slightly larger physical dimensions (0.098" diameter x 0.256" length versus 0.091" diameter x 0.244" length) do not create board layout conflicts or clearance issues in the target application.
