Substitute Part Grouping Explanation

The CT-20EP203 qualifies as a direct substitute for the CT-20EX203 based on identical electrical and mechanical parameters. Substitution criteria are strictly limited to the following verified parameters:

• Resistance value: 20 kOhms (exact match)
• Power rating: 0.5W / 1/2W (exact match)
• Tolerance: ±10% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Number of turns: 15 (exact match)
• Adjustment type: Side Adjustment (exact match)
• Resistive material: Cermet (exact match)
• Mounting type: Through Hole (exact match)
• Termination style: PC Pins (exact match)
• Physical dimensions: 0.252" x 0.197" Face / 6.40mm x 5.00mm (exact match)
• Compliance certifications: ROHS3, REACH Unaffected, MSL 1 (exact match)

Both parts belong to the CT20 series and maintain identical base specifications, confirming functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP203 be used as a direct replacement for CT-20EX203?

A: Yes. Both parts are manufactured by Nidec Components Corporation within the CT20 series and share identical electrical specifications (20 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C), mechanical dimensions (0.252" x 0.197" face), and termination characteristics (PC pins, through-hole, side adjustment). All compliance certifications match identically.

Q: Are there any differences in physical packaging or PCB footprint?

A: No. Both parts feature identical rectangular dimensions of 0.252" x 0.197" face (6.40mm x 5.00mm) with PC pin termination. PCB footprint and mounting requirements are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CT-20EX203 and CT-20EP203 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is rated 1 (unlimited) for both parts.

Q: What determines substitutability between these two part numbers?

A: Substitutability is determined by matching resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material composition, mounting method, termination style, physical dimensions, and regulatory compliance status. All these parameters are identical between CT-20EX203 and CT-20EP203.

Q: Is there a preferred part number for new designs?

A: Selection should be based on inventory availability and procurement lead times. Both parts carry Active product status with no technical advantage of one over the other.
