Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF14JA4M70 is determined by the following critical parameters:

• Resistance value: 4.7 MOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Temperature coefficient: 0 / -1500ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Number of terminations: 2 (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part PCF14JT4M70 maintains all electrical specifications and compliance certifications. The primary difference is the packaging configuration: the substitute uses Cut Tape (CT) packaging with Panasert radial bend capability, whereas the main part uses Tape & Box (TB) packaging in standard axial configuration. Both parts share identical physical dimensions and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CF14JA4M70 and PCF14JT4M70 are active production parts from Stackpole Electronics Inc with identical electrical specifications and full compliance certifications. Selection between these parts should be based on packaging and supply chain requirements:

The CF14JA4M70 in Tape & Box packaging is suitable for applications requiring standard axial component orientation and bulk packaging formats. The PCF14JT4M70 in Cut Tape packaging with radial bend capability provides flexibility for automated assembly processes that may require component lead bending or specific tape-based handling procedures. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can PCF14JT4M70 be used as a direct replacement for CF14JA4M70?

A: Yes. Both parts share identical electrical specifications: 4.7 MOhm resistance, ±5% tolerance, 0.25W power rating, carbon film composition, and operating temperature range of -55°C to 155°C. The primary difference is packaging format and lead configuration capability.

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

A: Tape & Box (TB) packaging provides components on tape with a protective box for storage and handling. Cut Tape (CT) packaging provides individual components on tape segments, typically used for automated pick-and-place assembly. The Panasert radial bend capability of the Cut Tape version allows for lead bending during assembly if required.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both CF14JA4M70 and PCF14JT4M70 have identical physical dimensions of 0.091" diameter × 0.236" length (2.30mm × 6.00mm), with 2 terminations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Which part should be selected for high-volume automated assembly?

A: PCF14JT4M70 in Cut Tape packaging is optimized for automated assembly processes. The Panasert radial bend configuration provides compatibility with standard pick-and-place equipment and tape-based component handling systems.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical temperature coefficients (0 / -1500ppm/°C), operating temperature ranges, and all other electrical characteristics. They are functionally equivalent for circuit performance.
