Key Parameters

Substitute Part Grouping Explanation

The CMF5540R200FHEB qualifies as a parametric equivalent to the CMF5540R200FHEA based on identical electrical and mechanical specifications. Substitution is determined by the following key parameters:

• Resistance value: 40.2 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.5W (exact match)
• Composition: Metal Film (exact match)
• Temperature coefficient: ±50ppm/°C (exact match)
• Operating temperature range: -55°C to 175°C (exact match)
• Package type: Axial (exact match)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match)
• Termination count: 2 (exact match)

The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Vishay Dale within the CMF series and maintain identical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CMF5540R200FHEA and CMF5540R200FHEB maintain Active product status with full ROHS3 compliance and identical electrical performance. Selection between these parts should be based on procurement and assembly requirements:

The CMF5540R200FHEA in Tape & Reel packaging is suitable for high-volume automated assembly operations requiring continuous reel feeding. The CMF5540R200FHEB in Cut Tape packaging accommodates lower-volume production runs, manual assembly processes, or applications where smaller quantity increments are required. Both parts satisfy identical circuit design requirements and thermal operating conditions. The REACH Unaffected status of the CMF5540R200FHEB may provide regulatory advantages in specific supply chain contexts, while the CMF5540R200FHEA maintains REACH Affected designation.

Frequently Asked Questions (FAQ)

Q: Can CMF5540R200FHEB be used as a direct replacement for CMF5540R200FHEA in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The 40.2 Ohm resistance value, ±1% tolerance, 0.5W power rating, temperature coefficient, and operating temperature range are identical. Physical dimensions and axial package configuration match exactly, enabling direct substitution in PCB layouts and through-hole assembly processes.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components in tape strips cut to specific lengths, typically used for manual assembly, lower-volume production, or component kitting. Both formats contain identical components with no electrical or mechanical differences.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The CMF5540R200FHEB is REACH Unaffected while the CMF5540R200FHEA is REACH Affected. This distinction may impact supply chain documentation and regulatory reporting requirements depending on end-use application and geographic distribution.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical with matching physical dimensions, they can be used interchangeably within the same circuit board assembly without performance impact or compatibility issues.

Q: What inventory considerations apply to these substitute parts?

A: The CMF5540R200FHEB maintains significantly higher stock availability (9321 Pcs) compared to the CMF5540R200FHEA (867 Pcs). For applications with extended lead time requirements or high-volume procurement needs, the CMF5540R200FHEB may offer supply chain advantages.
