Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM12JT2M70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.7 MOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Package: Axial through-hole
• Operating temperature range: -55°C to 155°C
• Temperature coefficient: 0 / -1500ppm/°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The CF12JT2M70 qualifies as a direct substitute based on identical electrical specifications and functional characteristics. Physical dimensions vary within acceptable mechanical tolerances for axial package form factors.

Parameter Comparison

Engineering Selection Recommendations

Both CFM12JT2M70 and CF12JT2M70 are active production parts from Stackpole Electronics Inc with identical electrical performance specifications. Selection between these parts is based on physical space constraints and board layout requirements. The CFM12JT2M70 features a more compact axial form factor (2.30mm diameter × 6.50mm length), while the CF12JT2M70 provides a standard axial configuration (2.70mm diameter × 8.50mm length). Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in equivalent applications. Inventory availability should be considered as a secondary factor in component selection.

Frequently Asked Questions (FAQ)

Q: Can CF12JT2M70 be used as a direct replacement for CFM12JT2M70?

A: Yes. Both parts share identical electrical specifications: 2.7 MOhms resistance, ±5% tolerance, 0.5W power rating, carbon film composition, and operating temperature range of -55°C to 155°C. The primary difference is physical dimension, with CF12JT2M70 being slightly larger in both diameter and length.

Q: What are the physical dimension differences between these parts?

A: CFM12JT2M70 measures 0.091" diameter × 0.256" length (2.30mm × 6.50mm). CF12JT2M70 measures 0.106" diameter × 0.335" length (2.70mm × 8.50mm). Both are axial through-hole packages suitable for standard PCB mounting.

Q: Are both parts RoHS compliant?

A: Yes. Both CFM12JT2M70 and CF12JT2M70 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What determines substitution eligibility for these resistors?

A: Substitution is based on matching resistance value (2.7 MOhms), tolerance (±5%), power rating (0.5W), composition (carbon film), package type (axial), operating temperature range (-55°C to 155°C), and compliance certifications. Physical dimensions are secondary considerations provided the axial package form factor is maintained.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is complete. Physical interchangeability depends on available board space. Applications with space constraints may require the more compact CFM12JT2M70, while standard layouts accommodate either configuration.
