Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF1/2DCT52R1001F are qualified based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

All substitute parts listed meet these criteria. Differences in packaging format (Cut Tape vs. Bulk vs. Tape & Reel) and physical dimensions do not affect electrical equivalence but may impact assembly and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the MF1/2DCT52R1001F. Selection among these parts should be based on:

Packaging Availability: MF1/2DC1001F is available in Bulk packaging, while MF1/2DCT52R1001F, CMF551K0000FKEA, and SFR16S0001001FR500 are supplied in Cut Tape format. Choose based on assembly line requirements and inventory management practices.

Compliance Status: All parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for current applications.

Temperature Range: CMF551K0000FKEA extends the operating temperature range to -55°C ~ 175°C, providing additional margin for high-temperature applications compared to the standard -55°C ~ 155°C range of other options.

Inventory Levels: SFR16S0001001FR500 maintains the highest inventory (43,986 pcs), followed by CMF551K0000FKEA (3,603 pcs), MF1/2DCT52R1001F (4,969 pcs), and MF1/2DC1001F (1,715 pcs). Inventory availability may influence selection for high-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can MF1/2DC1001F replace MF1/2DCT52R1001F in production? A: Yes. Both parts are identical in electrical specifications and axial package type. The only difference is packaging format (Bulk vs. Cut Tape). Verify that your assembly process accommodates the bulk packaging format.

Q: Is CMF551K0000FKEA a direct substitute? A: Yes, electrically and mechanically. CMF551K0000FKEA meets all core parameters. Note that it offers an extended operating temperature range (-55°C ~ 175°C) and includes flame retardant coating and moisture resistance features not specified in the original part.

Q: What are the physical dimension differences? A: MF1/2DCT52R1001F measures 0.138" Dia x 0.354" L (4.60mm x 9.00mm). CMF551K0000FKEA is smaller at 0.090" Dia x 0.240" L (2.29mm x 6.10mm). SFR16S0001001FR500 measures 0.075" Dia x 0.138" L (1.90mm x 4.60mm). Verify PCB layout compatibility before substitution.

Q: Are all substitutes RoHS compliant? A: Yes. All listed parts maintain ROHS3 compliance and REACH Unaffected status.

Q: Which substitute has the best availability? A: SFR16S0001001FR500 has the highest inventory at 43,986 pieces in stock.
