CFM14JT2M70 Equivalent & Substitute Parts

Part Overview

The CFM14JT2M70 is a 2.7 MOhms ±5% 0.25W through-hole axial resistor manufactured by Stackpole Electronics Inc. This carbon film resistor features flame retardant coating and safety characteristics, designed for applications requiring high-resistance values in compact form factors. The part is Active status and ROHS3 compliant. Substitute parts are necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative series variants meet identical electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for CFM14JT2M70 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 2.7 MOhms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Temperature coefficient: 0 / -1500ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: Axial
• Manufacturer: Stackpole Electronics Inc
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Packaging format (Tape & Reel vs. Cut Tape)
• Series designation (CFM vs. CF)
• Physical dimensions (within axial package constraints)

Two substitute parts meet these criteria: CF14JT2M70 (MFR Recommended) and CFM14JA2M70 (Parametric Equivalent).

Parameter Comparison

Engineering Selection Recommendations

All three parts—CFM14JT2M70, CF14JT2M70, and CFM14JA2M70—are electrically and functionally equivalent for applications requiring 2.7 MOhms ±5% 0.25W axial resistors. Selection between these parts is determined by packaging and supply chain requirements:

CF14JT2M70 is the MFR Recommended substitute, offering identical electrical specifications with Cut Tape packaging. This part is suitable when reel packaging is not required and provides higher inventory availability (13,260 pcs).

CFM14JA2M70 is the Parametric Equivalent, maintaining the CFM series designation with Cut Tape packaging. This part matches the original series lineage while providing alternative packaging format (8,781 pcs available).

All parts maintain Active product status, ROHS3 compliance, and REACH Unaffected designation, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can CF14JT2M70 be used as a direct replacement for CFM14JT2M70?

A: Yes. Both parts share identical electrical specifications: 2.7 MOhms ±5% tolerance, 0.25W power rating, carbon film composition, and -55°C to 155°C operating range. The primary difference is packaging format (Cut Tape vs. Tape & Reel). Electrical performance and circuit compatibility are equivalent.

Q: What is the difference between CFM14JA2M70 and CFM14JT2M70?

A: Both parts are from the CFM series with identical electrical parameters. The difference is packaging format: CFM14JT2M70 uses Tape & Reel, while CFM14JA2M70 uses Cut Tape. Physical dimensions vary slightly (CFM14JT2M70: 0.067" Dia x 0.130" L; CFM14JA2M70: 0.067" Dia x 0.130" L), but both are axial package types suitable for through-hole mounting.

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

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification. Regulatory status is identical across all substitutes.

Q: Which substitute should be selected for new designs?

A: Selection depends on procurement requirements. CF14JT2M70 offers the highest inventory availability and MFR recommendation status. CFM14JA2M70 maintains series continuity with the original CFM designation. Both are Active status parts with equivalent electrical performance.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the PCB layout and assembly equipment accommodate the packaging format. All three parts are axial through-hole resistors with identical electrical specifications and operating characteristics. Mechanical fit depends on board design and component spacing.
