Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM12JT1M10 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.1 MOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Package configuration: Axial through-hole
• Temperature coefficient: 0 / -1500ppm/°C
• Operating temperature range: -55°C to 155°C
• Compliance certifications: ROHS3, REACH Unaffected

The identified substitute part CF12JT1M10 maintains complete electrical and mechanical equivalence. The primary distinction between the main part and substitute is the packaging format: CFM12JT1M10 is supplied in Tape & Reel (TR) configuration, while CF12JT1M10 is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Stackpole Electronics Inc and share identical component specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CFM12JT1M10 and CF12JT1M10 are active production parts with identical electrical specifications and full compliance certifications. Selection between these parts is determined by packaging requirements and assembly process compatibility.

The CFM12JT1M10 in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous component feed. The CF12JT1M10 in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or applications where individual component handling is preferred.

Physical dimensions differ between the two parts. The CFM12JT1M10 measures 0.091" diameter by 0.256" length, while the CF12JT1M10 measures 0.106" diameter by 0.335" length. PCB layout and component spacing must accommodate these dimensional variations to ensure proper fit and clearance.

Both parts maintain ROHS3 compliance and REACH unaffected status, supporting equivalent environmental and regulatory requirements across applications.

Frequently Asked Questions (FAQ)

Q: Are CFM12JT1M10 and CF12JT1M10 electrically identical?

A: Yes. Both parts share identical resistance value (1.1 MOhms), tolerance (±5%), power rating (0.5W), temperature coefficient (0 / -1500ppm/°C), and operating temperature range (-55°C to 155°C). Electrical performance is equivalent.

Q: What is the primary difference between these parts?

A: The packaging format differs. CFM12JT1M10 is supplied in Tape & Reel (TR) configuration for automated assembly. CF12JT1M10 is supplied in Cut Tape (CT) configuration for manual or lower-volume assembly processes.

Q: Do the physical dimensions differ?

A: Yes. CFM12JT1M10 measures 0.091" diameter by 0.256" length (2.30mm x 6.50mm). CF12JT1M10 measures 0.106" diameter by 0.335" length (2.70mm x 8.50mm). PCB layout must accommodate these dimensional differences.

Q: Can I substitute CF12JT1M10 for CFM12JT1M10 in my design?

A: Substitution is possible if the PCB layout accommodates the larger physical dimensions of CF12JT1M10 and if your assembly process supports Cut Tape packaging. Electrical performance remains equivalent.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both CFM12JT1M10 and CF12JT1M10 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: Which part should I select for high-volume production?

A: CFM12JT1M10 in Tape & Reel format is optimized for high-volume automated assembly operations. CF12JT1M10 in Cut Tape format is suitable for lower-volume or manual assembly processes.
