Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCS04020C2749FE000 is determined by the following critical parameters:

• Resistance value: 27.4 Ohms (exact match required)
• Package type: 0402 (1005 Metric) form factor
• Power rating: 0.063W minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The CPF0402B27R4E1 meets all substitution criteria. While this part features improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations from the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the MCS04020C2749FE000 and CPF0402B27R4E1 are Active products with ROHS3 compliance and MSL 1 ratings. The CPF0402B27R4E1 provides tighter tolerance specification (±0.1%) and improved temperature coefficient performance (±25ppm/°C) while maintaining identical resistance value, power rating, package form factor, and operating temperature range. Both components are suitable for direct substitution in 0402 thin film resistor applications requiring 27.4 Ohm resistance.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B27R4E1 directly replace MCS04020C2749FE000 in existing designs?

A: Yes. Both parts share identical resistance value (27.4 Ohms), power rating (0.063W), package type (0402), composition (thin film), and operating temperature range (-55°C to 155°C). Physical dimensions are equivalent with negligible height difference (0.37mm versus 0.35mm seated height).

Q: What is the significance of the tolerance difference between these parts?

A: The MCS04020C2749FE000 specifies ±1% tolerance while the CPF0402B27R4E1 specifies ±0.1% tolerance. The substitute part offers improved tolerance performance. Applications requiring tighter resistance accuracy benefit from the CPF0402B27R4E1 specification.

Q: Are there package compatibility concerns?

A: No. Both components use the 0402 (1005 Metric) package with identical footprint dimensions (1.00mm x 0.50mm). PCB layout and reflow profiles remain unchanged.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the MCS04020C2749FE000 and CPF0402B27R4E1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard manufacturing and storage conditions.

Q: What is the temperature coefficient difference and when does it matter?

A: The MCS04020C2749FE000 has ±50ppm/°C temperature coefficient while CPF0402B27R4E1 has ±25ppm/°C. Applications with wide operating temperature ranges or requiring stable resistance across temperature extremes benefit from the lower temperature coefficient of the substitute part.
