LR1F261R Equivalent & Substitute Parts

Part Overview

The LR1F261R is a 261 Ohms ±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 electronic applications requiring precision resistance values with tight tolerance specifications. The part maintains Active product status with 920 pieces currently in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F261R is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters:

• Resistance value: 261 Ohms
• Tolerance: ±1%
• Power rating: 0.6W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package configuration: Axial
• Number of terminations: 2

Compliance Parameters:

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

The substitute part MRS25000C2610FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components satisfies all critical electrical and mechanical parameters. Physical dimensions vary slightly between the main part and substitute (diameter and length differences within acceptable axial resistor tolerances), and packaging format differs (Tape & Box versus Cut Tape), but these variations do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F261R and MRS25000C2610FCT00 are Active products with ROHS3 compliance and identical electrical specifications. Selection between these parts is based on procurement and application requirements:

LR1F261R Selection Criteria:

• TE Connectivity Neohm series preference
• Tape & Box packaging requirement
• Smaller physical footprint (0.091" diameter, 0.244" length)
• Current inventory availability (920 pieces)

MRS25000C2610FCT00 Selection Criteria:

• Vishay Beyschlag/Draloric/BC Components sourcing preference
• Cut Tape packaging requirement
• Slightly larger physical dimensions (0.098" diameter, 0.256" length)
• Higher inventory availability (4087 pieces)
• MRS25 series specification alignment

Both parts satisfy identical electrical performance requirements, operating temperature ranges, and regulatory compliance standards. Physical dimension differences are within acceptable tolerances for axial resistor applications and do not impact circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C2610FCT00 be used as a direct replacement for LR1F261R?

A: Yes. Both parts share identical electrical specifications: 261 Ohms ±1% tolerance, 0.6W power rating, metal film composition, ±50ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both are ROHS3 compliant with EAR99 classification. Physical dimensions differ slightly, but both are axial configuration with two terminations suitable for through-hole mounting.

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

A: The LR1F261R measures 0.091" diameter × 0.244" length (2.30mm × 6.20mm). The MRS25000C2610FCT00 measures 0.098" diameter × 0.256" length (2.50mm × 6.50mm). These variations are within standard axial resistor tolerances and do not affect circuit board layout compatibility for most applications.

Q: Do packaging format differences affect part selection?

A: Packaging format differs between parts: LR1F261R is supplied in Tape & Box (TB) format, while MRS25000C2610FCT00 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and inventory management preferences. Both formats are standard for through-hole resistor distribution.

Q: Are both parts currently available?

A: Yes. LR1F261R has 920 pieces in stock. MRS25000C2610FCT00 has 4087 pieces in stock. Availability may vary based on procurement timing and supplier inventory levels.

Q: Do these parts have identical compliance certifications?

A: Yes. Both parts are ROHS3 compliant, classified as EAR99 for export control purposes, and assigned HTSUS code 8533.21.0090. Both maintain Active product status.
