Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JA2M00 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 2 MOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Temperature Coefficient: 0 / -1500ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CF14JA2M00 meets all substitution criteria and is classified as a manufacturer-recommended equivalent. Physical dimensions vary between the main part and substitute, but both conform to standard axial package specifications and are functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CFM14JA2M00 and CF14JA2M00 are active production parts from Stackpole Electronics Inc with identical electrical specifications and regulatory compliance status. Selection between these parts should be based on:

• Availability: CFM14JA2M00 maintains higher inventory (883 units) compared to CF14JA2M00 (624 units)
• Physical Footprint: CF14JA2M00 has larger axial dimensions (0.091" Dia x 0.236" L) versus CFM14JA2M00 (0.067" Dia x 0.130" L). PCB layout constraints may dictate preference for the more compact CFM14JA2M00
• Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements for applications subject to these standards
• Series Designation: CFM14JA2M00 belongs to the CFM series; CF14JA2M00 belongs to the CF series. Both are Stackpole carbon film resistor lines with equivalent performance characteristics

Frequently Asked Questions (FAQ)

Q: Can CF14JA2M00 be used as a direct replacement for CFM14JA2M00?

A: Yes. Both parts share identical electrical specifications: 2 MOhms resistance, ±5% tolerance, 0.25W power rating, carbon film composition, and operating temperature range of -55°C to 155°C. Both are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between these two parts?

A: The main difference is physical dimension. CFM14JA2M00 measures 0.067" diameter by 0.130" length, while CF14JA2M00 measures 0.091" diameter by 0.236" length. Both are standard axial through-hole packages. PCB layout requirements may influence selection based on available space.

Q: Are there any compatibility concerns when substituting CF14JA2M00 for CFM14JA2M00?

A: No compatibility concerns exist from an electrical standpoint. Both parts are functionally equivalent. Physical board layout must accommodate the larger dimensions of CF14JA2M00 if space is constrained.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CFM14JA2M00 and CF14JA2M00 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on design constraints. For space-critical applications, CFM14JA2M00 is preferred due to smaller dimensions. For general applications where footprint is not a limiting factor, either part is suitable based on availability and lead time.
