Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6EP100 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Power Rating: 0.5W (1/2W)
• Adjustment Type: Top Adjustment
• Resistive Material: Cermet
• Mounting Type: Through Hole
• Termination Style: PC Pins
• Tolerance: ±10%

Allowable Variation Parameters:

• Resistance Value: May differ based on circuit design requirements
• Temperature Coefficient: May vary within acceptable operating ranges
• Physical Dimensions: May differ if PCB layout permits
• Packaging Format: May differ (Bulk vs. Tube)

The substitute part 3329H-1-101LF from Bourns Inc. maintains compatibility across all mandatory parameters while offering a different resistance value (100 Ohms) and improved temperature coefficient performance (±100ppm/°C vs. ±250ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6EP100 and 3329H-1-101LF maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection between these components should be based on:

CT-6EP100 Selection Criteria:

• Applications requiring 10 Ohm resistance value
• Square form factor compatibility with existing PCB layouts
• Acceptable temperature coefficient performance at ±250ppm/°C

3329H-1-101LF Selection Criteria:

• Applications requiring 100 Ohm resistance value
• Superior temperature stability requirement (±100ppm/°C)
• Round form factor accommodation in PCB design
• Tube packaging preference for automated assembly processes

Both parts share identical power ratings, tolerance specifications, and core functional characteristics. The primary differentiators are resistance value, temperature coefficient, physical form factor, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-101LF directly replace the CT-6EP100 without circuit modifications?

A: Direct replacement is not possible due to the 10x difference in resistance value (10 Ohms vs. 100 Ohms). Circuit design modifications are required to accommodate the different resistance specification.

Q: Are both parts suitable for the same power dissipation requirements?

A: Yes. Both components are rated at 0.5W (1/2W) and share identical power handling capabilities.

Q: What is the significance of the temperature coefficient difference?

A: The 3329H-1-101LF offers superior temperature stability (±100ppm/°C) compared to the CT-6EP100 (±250ppm/°C). This means the Bourns component maintains more consistent resistance values across temperature variations, beneficial for precision applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and actively manufactured, ensuring regulatory compliance and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Yes. The CT-6EP100 is supplied in Bulk packaging, while the 3329H-1-101LF is supplied in Tube packaging. This affects handling and automated assembly processes.

Q: Can the physical size difference affect PCB compatibility?

A: Yes. The CT-6EP100 features a square form factor (7.00mm x 7.00mm), while the 3329H-1-101LF is round (6.35mm diameter). PCB layout verification is required to confirm mechanical fit.
