LR1F56R2 Equivalent & Substitute Parts

Part Overview

The LR1F56R2 is a 56.2 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 classified as Active and maintains ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

The substitute parts MRS25000C5629FCT00 and MRS25000C5629FRP00 from Vishay Beyschlag/Draloric/BC Components meet all electrical specifications and mechanical requirements. Physical dimensions vary slightly (0.098" Dia x 0.256" L versus 0.091" Dia x 0.244" L), which remains within acceptable tolerances for axial through-hole component placement in standard PCB designs.

Parameter Comparison

Engineering Selection Recommendations

All three components—LR1F56R2, MRS25000C5629FCT00, and MRS25000C5629FRP00—are functionally equivalent for applications requiring a 56.2 Ohm ±1% 0.6W axial metal film resistor. Selection between these parts is determined by:

Availability and Inventory: MRS25000C5629FRP00 maintains 7,126 pieces in stock, while MRS25000C5629FCT00 maintains 6,212 pieces. The LR1F56R2 has 800 pieces available.

Packaging Format: LR1F56R2 is supplied in Tape & Box (TB) format. Both Vishay substitutes are supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and handling procedures.

Compliance Status: All parts maintain ROHS3 compliance and EAR99 ECCN classification. Vishay parts carry REACH Unaffected status, while TE Connectivity part status is Vendor Undefined.

Physical Dimensions: Slight dimensional variations exist (LR1F56R2: 0.091" Dia x 0.244" L; Vishay parts: 0.098" Dia x 0.256" L). These differences are acceptable for standard through-hole PCB designs with conventional component spacing.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C5629FCT00 and MRS25000C5629FRP00 be used interchangeably with LR1F56R2?

A: Yes. All three components share identical electrical specifications (56.2 Ohms ±1%, 0.6W, metal film, ±50ppm/°C, -55°C to 155°C operating range) and axial through-hole package configuration. The primary difference is packaging format (Tape & Box versus Cut Tape) and minor physical dimensions.

Q: What is the difference between MRS25000C5629FCT00 and MRS25000C5629FRP00?

A: Both parts are electrically and mechanically identical. The designation difference (FCT00 versus FRP00) reflects packaging tape specifications. Both are supplied in Cut Tape format and maintain equivalent performance characteristics.

Q: Are there any dimensional compatibility concerns when substituting these parts?

A: Physical dimensions vary slightly between manufacturers. LR1F56R2 measures 0.091" Dia x 0.244" L, while Vishay parts measure 0.098" Dia x 0.256" L. These variations remain within acceptable tolerances for standard through-hole PCB designs with conventional component lead spacing and do not affect electrical performance or mechanical fit in typical applications.

Q: Do all substitute parts maintain the same compliance certifications?

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. Compliance requirements for specific applications should be verified against end-use regulations.

Q: Which packaging format should be selected for automated assembly?

A: Cut Tape (CT) format, supplied by both Vishay substitutes, is standard for automated pick-and-place assembly equipment. Tape & Box (TB) format, supplied by TE Connectivity, is suitable for manual assembly or bulk component handling. Selection depends on manufacturing process capabilities.
