Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF5522K100FKBF70 is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 22.1 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package type: Axial

Mechanical Parameters (Must Match):

• Physical dimensions compatible with axial through-hole mounting
• Two terminations

Allowable Variations:

• Packaging format (Bulk, Cut Tape, Tape & Reel)
• Temperature coefficient (within acceptable operating range)
• Maximum operating temperature (equal to or exceeding -55°C ~ 175°C)
• Compliance certifications (RoHS, REACH status)

All substitute parts listed maintain identical electrical specifications and mechanical compatibility while differing only in packaging, temperature coefficient, or regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

CMF5522K100FHEB (Vishay Dale, Cut Tape): This substitute offers improved temperature coefficient (±50ppm/°C vs ±100ppm/°C) and ROHS3 compliance with REACH unaffected status. Suitable for applications requiring enhanced regulatory compliance and tighter temperature stability. Cut Tape packaging accommodates automated assembly processes.

CMF5522K100FHEK (Vishay Dale, Bulk): Identical electrical performance to CMF5522K100FHEB with ROHS3 compliance and REACH unaffected status. Bulk packaging matches the original part format. Temperature coefficient improvement (±50ppm/°C) provides enhanced stability for precision circuit applications.

RNMF12FTD22K1 (Stackpole Electronics Inc, Tape & Reel): Cross-manufacturer substitute from Stackpole Electronics Inc RNMF (Mini) series. Maintains all critical electrical parameters with ROHS3 compliance. Physical dimensions show minor variation (0.093" Dia x 0.250" L vs 0.090" Dia x 0.240" L) within acceptable axial through-hole mounting tolerances. Maximum operating temperature limited to 155°C (vs 175°C). Tape & Reel packaging supports high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can CMF5522K100FHEB replace CMF5522K100FKBF70 in existing designs?

A: Yes. Both parts share identical resistance (22.1 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and axial package type. The substitute offers superior temperature coefficient (±50ppm/°C) and improved regulatory compliance (ROHS3, REACH unaffected). Packaging differs (Cut Tape vs Bulk) but does not affect electrical performance.

Q: What is the significance of the temperature coefficient difference?

A: CMF5522K100FKBF70 has ±100ppm/°C while CMF5522K100FHEB and CMF5522K100FHEK have ±50ppm/°C. Lower temperature coefficient indicates reduced resistance variation across the operating temperature range, beneficial for precision analog circuits. Both values remain within acceptable ranges for standard industrial applications.

Q: Is RNMF12FTD22K1 mechanically compatible with the original part?

A: RNMF12FTD22K1 has slightly larger dimensions (0.093" Dia x 0.250" L vs 0.090" Dia x 0.240" L). Both are axial through-hole resistors with two terminations. The dimensional difference is minor and typically accommodated by standard PCB hole spacing and component placement tolerances. Verify PCB layout constraints for space-critical applications.

Q: Why does RNMF12FTD22K1 have a lower maximum operating temperature?

A: RNMF12FTD22K1 operates to 155°C maximum versus 175°C for the Vishay Dale parts. This difference reflects design specifications of the Stackpole RNMF series. For applications operating below 155°C, this substitute remains fully compatible.

Q: What packaging formats are available?

A: CMF5522K100FKBF70 and CMF5522K100FHEK are supplied in Bulk format. CMF5522K100FHEB is supplied in Cut Tape (CT). RNMF12FTD22K1 is supplied in Tape & Reel (TR). Selection depends on assembly process requirements and order quantity.

Q: Are all substitutes RoHS compliant?

A: CMF5522K100FHEB, CMF5522K100FHEK, and RNMF12FTD22K1 are ROHS3 compliant. The original CMF5522K100FKBF70 is RoHS non-compliant. For applications requiring RoHS compliance, use one of the three substitute parts.
