Substitute Part Grouping Explanation

The CT-20EP502 qualifies as a direct substitute for the CT-20EX502 based on the following alignment of critical parameters:

• Identical resistance value: 5 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

The substitution is based on functional equivalence across all specified electrical and mechanical parameters. Both parts belong to the Nidec Components Corporation CT20 series and maintain identical performance characteristics within the defined tolerance and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-20EX502 and CT-20EP502 are active production components from Nidec Components Corporation with full ROHS3 compliance and REACH unaffected status. Selection between these parts may be based on inventory availability, as the CT-20EP502 currently maintains higher stock levels (1178 units versus 824 units). Both components meet identical electrical performance specifications and physical form factor requirements. The difference between part numbers reflects internal manufacturer designation within the CT20 series; no functional or performance distinction exists between the EX and EP variants for the specified 5 kOhm, 0.5W configuration.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP502 be used as a direct replacement for CT-20EX502?

A: Yes. Both parts share identical electrical specifications (5 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C), mechanical dimensions (0.252" x 0.197" rectangular face), and termination configuration (PC pins, through-hole, side adjustment). All compliance certifications and environmental ratings are equivalent.

Q: What is the difference between the EX and EP designations?

A: The EX and EP designations represent different internal product codes within the Nidec Components Corporation CT20 series. No functional, electrical, or mechanical differences exist between these variants for the 5 kOhm, 0.5W specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts feature identical rectangular dimensions of 0.252" x 0.197" face (6.40mm x 5.00mm), ensuring equivalent PCB footprint and mounting compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both CT-20EX502 and CT-20EP502 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected based on availability?

A: CT-20EP502 currently maintains higher inventory (1178 units) compared to CT-20EX502 (824 units). Selection may prioritize the substitute part for supply chain continuity when stock levels are a consideration.

Q: Are the adjustment characteristics identical?

A: Yes. Both parts feature 15-turn side adjustment with cermet resistive material, providing identical adjustment resolution and control characteristics.
