Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-20EX102 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 15
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.252" x 0.197" Face (6.40mm x 5.00mm)
• Compliance certifications: RoHS3, REACH Unaffected

The CT-20EP102 qualifies as a direct substitute because it maintains identical electrical performance, mechanical configuration, and regulatory compliance across all specified parameters within the CT20 series.

Parameter Comparison

Engineering Selection Recommendations

Both CT-20EX102 and CT-20EP102 maintain Active product status with identical regulatory compliance profiles. The CT-20EP102 carries higher inventory availability (1607 pcs vs. 1020 pcs), making it suitable for high-volume procurement scenarios where supply continuity is a consideration. Both parts satisfy RoHS3 and REACH requirements without exception. Selection between these parts should be based on procurement lead times, inventory allocation, and supply chain logistics rather than electrical or mechanical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP102 replace CT-20EX102 in existing designs?

A: Yes. The CT-20EP102 is electrically and mechanically equivalent across all specified parameters. No circuit redesign or PCB layout modification is required.

Q: Are there dimensional differences between these parts?

A: No. Both parts share identical rectangular dimensions of 0.252" x 0.197" face (6.40mm x 5.00mm), ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CT-20EX102 and CT-20EP102 are RoHS3 compliant and REACH unaffected, with identical moisture sensitivity ratings of MSL 1 (Unlimited).

Q: What is the difference between the CT20EX and CT20EP base product numbers?

A: The base product numbers (CT20EX vs. CT20EP) indicate different internal manufacturing or packaging designations within the CT20 series. Both maintain identical electrical performance and mechanical specifications for the 1 kOhms 0.5W configuration.

Q: Are adjustment characteristics identical between these parts?

A: Yes. Both parts feature 15-turn side adjustment with cermet resistive material and ±100ppm/°C temperature coefficient, ensuring equivalent tuning resolution and stability.
