Substitute Part Grouping Explanation

Substitution for the CMF556K8100DHRE is based on strict electrical and mechanical parameter matching within the CMF series. The allowed substitution criteria are:

• Identical resistance value: 6.81 kOhms
• Identical tolerance: ±0.5%
• Identical power rating: 0.5W (1/2W)
• Identical composition: Metal Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C to 175°C
• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia × 0.240" L
• Identical features: Flame Retardant Coating, Moisture Resistant, Safety

The CMF556K8100DHR6 meets all electrical and mechanical requirements for direct substitution. The only difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats contain identical components with no functional or performance differences.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF556K8100DHRE and CMF556K8100DHR6 are active production components from Vishay Dale with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on packaging format requirements:

• CMF556K8100DHRE (Tape & Reel): Suitable for automated assembly processes requiring continuous reel feeding
• CMF556K8100DHR6 (Cut Tape): Suitable for manual assembly, small batch production, or applications where individual component handling is preferred

Both parts share identical RoHS non-compliant and REACH Affected compliance status. No functional or performance differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can CMF556K8100DHR6 be used as a direct replacement for CMF556K8100DHRE?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape). Substitution is valid for any application where the CMF556K8100DHRE is specified.

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

A: Tape & Reel (TR) format supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) format supplies components in individual tape segments suitable for manual assembly or lower-volume production. The components themselves are identical.

Q: Are there any performance differences between these two part numbers?

A: No. Both parts have identical resistance (6.81 kOhms), tolerance (±0.5%), power rating (0.5W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 175°C). Performance is equivalent.

Q: What compliance certifications apply to both parts?

A: Both parts share identical compliance status: RoHS non-compliant and REACH Affected. No differences exist in regulatory compliance between the two variants.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process can accommodate the packaging format. Automated assembly lines typically use Tape & Reel format, while manual or semi-automated processes may use Cut Tape format. The physical component dimensions are identical (0.090" Dia × 0.240" L), ensuring mechanical compatibility in all applications.
