MBA02040C2940FRP00 Equivalent & Substitute Parts

Part Overview

The MBA02040C2940FRP00 is a 294 Ohms ±1% 0.4W through-hole resistor in axial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components. This metal film resistor meets automotive AEC-Q200 qualification standards and operates across the temperature range of -55°C to 155°C. The component is actively produced and stocked, with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when the original part becomes unavailable, when procurement lead times are excessive, or when alternative packaging formats better suit assembly requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBA02040C2940FRP00 is determined by the following critical parameters:

• Resistance value: 294 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 and REACH status (exact match required)

The identified substitute part SFR2500002940FR500 satisfies all mandatory electrical parameters and regulatory requirements. Physical dimensions and packaging format differ (Cut Tape versus Tape & Reel), but both configurations deliver identical electrical performance in axial through-hole applications. Temperature coefficient variation (±50ppm/°C versus ±100ppm/°C) remains within acceptable tolerance for standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both MBA02040C2940FRP00 and SFR2500002940FR500 are active production components with identical electrical specifications and regulatory compliance. Selection between these parts depends on procurement and assembly requirements rather than electrical performance.

The MBA02040C2940FRP00 in Tape & Reel packaging is optimized for high-volume automated assembly operations. The SFR2500002940FR500 in Cut Tape packaging provides flexibility for lower-volume builds, prototype development, and manual assembly workflows. Both components meet ROHS3 and REACH requirements for regulated markets.

Physical dimension differences (1.60mm versus 2.50mm diameter; 3.60mm versus 6.50mm length) must be evaluated against PCB layout constraints and mechanical clearance requirements. The larger SFR25 series body may require design accommodation in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can SFR2500002940FR500 replace MBA02040C2940FRP00 in existing designs?

A: Yes. Both components deliver identical electrical performance with 294 Ohms ±1% resistance, 0.4W power rating, and -55°C to 155°C operating range. Physical dimensions differ, requiring verification of PCB layout compatibility and mechanical clearance.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly at high volumes. Cut Tape (CT) packaging provides individual tape segments, suitable for lower-volume orders and manual assembly. Both formats contain identical components.

Q: Does the temperature coefficient difference affect circuit performance?

A: The MBA02040C2940FRP00 specifies ±50ppm/°C while SFR2500002940FR500 specifies ±100ppm/°C. For most standard applications, this difference remains negligible. Critical precision circuits requiring tight temperature stability should evaluate this parameter against specific design tolerances.

Q: Are both parts automotive qualified?

A: The MBA02040C2940FRP00 carries AEC-Q200 automotive qualification. The SFR2500002940FR500 does not list automotive qualification features. For automotive applications requiring AEC-Q200 compliance, the MBA02040C2940FRP00 is the specified choice.

Q: What inventory considerations apply to these parts?

A: MBA02040C2940FRP00 maintains 755 pieces in stock. SFR2500002940FR500 maintains 15,009 pieces in stock. Higher SFR25 series inventory may provide procurement advantages for extended lead-time mitigation.
