Key Parameters

Substitute Part Grouping Explanation

The CT-20EP202 qualifies as a direct substitute for the CT-20EX202 based on the following alignment of critical parameters:

• Identical resistance value: 2 kOhms
• Matching power rating: 0.5W (1/2W)
• Equivalent tolerance: ±10%
• Same temperature coefficient: ±100ppm/°C
• Identical turn count: 15 turns
• Matching adjustment type: Side Adjustment
• Same resistive material: Cermet
• Identical mounting configuration: Through Hole
• Matching termination: PC Pins
• Equivalent physical dimensions: Rectangular - 0.252" x 0.197" Face (6.40mm x 5.00mm)
• Equivalent compliance: ROHS3 Compliant, MSL 1, REACH Unaffected

Both components are manufactured by Nidec Components Corporation within the CT20 series and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-20EX202 and CT-20EP202 maintain active product status with equivalent compliance certifications. The CT-20EX202 currently has 1092 units in inventory, while the CT-20EP202 has 1047 units available. Selection between these parts should be based on inventory availability and supply chain requirements, as all electrical, mechanical, and regulatory parameters are identical. Both components satisfy ROHS3 compliance and REACH requirements, making either suitable for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP202 be used as a direct replacement for CT-20EX202?

A: Yes. The CT-20EP202 is a direct substitute. All electrical parameters (resistance, power rating, tolerance, temperature coefficient), mechanical specifications (dimensions, mounting type, termination style), and compliance certifications are identical between the two parts.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching resistance value (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (15), adjustment type (side adjustment), resistive material (cermet), mounting configuration (through hole), termination style (PC pins), and physical dimensions (0.252" x 0.197" face). Both parts must also maintain equivalent compliance status.

Q: Are there any differences in packaging or handling between these parts?

A: Both parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the difference between the CT-20EX and CT-20EP base product numbers?

A: The base product numbers (CT20EX and CT20EP) represent different internal designations within the Nidec CT20 series. However, when paired with the identical resistance value (202 = 2 kOhms) and specifications, the resulting parts are functionally equivalent for circuit applications.

Q: Are both parts currently available?

A: Yes. The CT-20EX202 has 1092 units in stock, and the CT-20EP202 has 1047 units in stock, both listed as new original inventory.
