Key Parameters

Substitute Part Grouping Explanation

The CFM14JT39K0 qualifies as a direct substitute based on the following critical parameters:

• Resistance Value: Both parts specify 39 kOhms
• Tolerance: Both maintain ±5% tolerance
• Power Rating: Both rated at 0.25W (1/4W)
• Composition: Both utilize carbon film construction
• Package Configuration: Both employ axial through-hole packaging
• Operating Temperature Range: Both support -55°C ~ 155°C
• Termination Count: Both feature 2 terminations
• Regulatory Compliance: Both classified under ECCN EAR99 and HTSUS 8533.10.0065

Physical dimensions show minor variation (1.70mm x 3.20mm versus 1.70mm x 3.30mm), which remains within acceptable tolerance for standard PCB footprints designed for axial resistors.

Parameter Comparison

Engineering Selection Recommendations

The CFM14JT39K0 is the appropriate substitute for ERD-S2TJ393V applications based on the following factors:

• Product Availability: The CFM14JT39K0 maintains active product status with 12,150 units in stock, compared to the obsolete ERD-S2TJ393V with limited remaining inventory.
• Electrical Equivalence: Identical resistance, tolerance, power rating, and operating temperature range ensure direct functional replacement.
• Regulatory Compliance: Both parts comply with ECCN EAR99 and HTSUS 8533.10.0065 classifications. The CFM14JT39K0 additionally carries ROHS3 compliance and REACH unaffected status.
• Physical Compatibility: Axial package configuration and 0.067" diameter remain consistent. The 0.004" (0.10mm) length difference is negligible for standard PCB layouts.
• Composition and Features: Both employ carbon film construction. The CFM14JT39K0 includes flame retardant coating and safety features, providing enhanced reliability.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT39K0 replace ERD-S2TJ393V in existing designs?

A: Yes. Both parts share identical electrical specifications (39 kOhms ±5%, 0.25W), operating temperature range (-55°C ~ 155°C), and axial package configuration. The minor physical dimension difference (0.10mm length) does not affect PCB footprint compatibility for standard axial resistor layouts.

Q: What is the difference in temperature coefficient between these parts?

A: The ERD-S2TJ393V specifies -150/-350ppm/°C, while the CFM14JT39K0 specifies 0/-500ppm/°C. Both values fall within acceptable ranges for carbon film resistors and do not impact substitution suitability for standard applications.

Q: Does the CFM14JT39K0 require different handling or storage procedures?

A: The CFM14JT39K0 lists Moisture Sensitivity Level as Not Applicable, compared to the ERD-S2TJ393V MSL 1 (Unlimited). This indicates the Stackpole part requires no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Are there regulatory or compliance differences?

A: Both parts comply with ECCN EAR99 and HTSUS 8533.10.0065. The CFM14JT39K0 additionally carries ROHS3 compliance and REACH unaffected status, making it suitable for applications with enhanced environmental or regulatory requirements.

Q: What packaging options are available for the CFM14JT39K0?

A: The CFM14JT39K0 is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes and component handling.
