Key Parameters

Substitute Part Grouping Explanation

Substitution between CF12JT2M00 and CFM12JT2M00 is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 2 MOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Temperature coefficient: 0 / -1500ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Compatible):

• Package type: Axial (both parts)
• Number of terminations: 2 (both parts)
• Features: Flame Retardant Coating, Safety (both parts)

Compliance Parameters (Identical):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8533.10.0065

The primary difference between these parts is packaging format (Tape & Reel versus Cut Tape) and physical dimensions, which do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT2M00 and CFM12JT2M00 are suitable for direct substitution in circuit applications requiring a 2 MOhms ±5% 0.5W axial resistor. Selection between these parts should be based on:

Packaging Requirements: CF12JT2M00 is supplied in Tape & Reel format, suitable for automated assembly processes. CFM12JT2M00 is supplied in Cut Tape format, suitable for manual assembly or lower-volume applications.

Inventory Availability: CFM12JT2M00 has significantly higher inventory availability (16,228 Pcs) compared to CF12JT2M00 (990 Pcs), making it the preferred choice when lead time and stock levels are considerations.

Compliance Certification: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met regardless of which part is selected.

Physical Dimensions: While dimensional differences exist between the two parts, both maintain axial package configuration compatible with standard through-hole PCB layouts. Physical dimensions should be verified against specific PCB design constraints if space limitations are present.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT2M00 be used as a direct replacement for CF12JT2M00 in production?

A: Yes. Both parts have identical electrical specifications (2 MOhms ±5%, 0.5W power rating, carbon film composition, temperature coefficient, and operating temperature range). The primary difference is packaging format (Tape & Reel versus Cut Tape) and physical dimensions. Substitution is valid for circuit functionality.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging (CF12JT2M00) is designed for automated pick-and-place assembly equipment. Cut Tape packaging (CFM12JT2M00) consists of individual components cut from the tape, suitable for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CF12JT2M00 and CFM12JT2M00 are ROHS3 compliant and REACH unaffected. They carry identical ECCN (EAR99) and HTSUS (8533.10.0065) classifications.

Q: Do the physical dimension differences affect PCB compatibility?

A: Both parts maintain axial package configuration and 2-termination design compatible with standard through-hole PCB layouts. However, the specific dimensions should be verified against PCB design constraints if space is limited. CF12JT2M00 measures 0.106" Dia x 0.335" L, while CFM12JT2M00 measures 0.091" Dia x 0.256" L.

Q: Which part should be selected for new designs?

A: Selection should be based on assembly process requirements and inventory availability. CFM12JT2M00 offers higher stock availability and is suitable for both manual and automated assembly. CF12JT2M00 is optimized for high-volume automated production using Tape & Reel equipment.
