Substitute Part Grouping Explanation

Substitute parts for the CT20P102 are grouped based on electrical and mechanical parameter compatibility. The primary substitution criteria are:

• Resistance value: 1 kOhms
• Power rating: 0.5W minimum
• 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 configuration within acceptable tolerance

CT-20EP102 and CT-20EX102 are direct electrical and mechanical equivalents manufactured by Nidec Components Corporation, maintaining identical specifications across all critical parameters. The 3006P-1-102 from Bourns Inc. is a manufacturer-recommended substitute with a higher power rating (0.75W) and marginally different physical dimensions, suitable for applications where increased power dissipation capacity is beneficial.

Parameter Comparison

Engineering Selection Recommendations

CT-20EP102 and CT-20EX102 are preferred substitutes for the obsolete CT20P102. Both parts are manufactured by Nidec Components Corporation with active product status and ROHS3 compliance. These parts maintain identical electrical specifications and physical dimensions, ensuring direct compatibility in existing designs without circuit modification or PCB redesign.

The 3006P-1-102 from Bourns Inc. is a manufacturer-recommended alternative with increased power rating (0.75W versus 0.5W) and marginally reduced physical dimensions (0.250" x 0.190" versus 0.252" x 0.197"). This part maintains all critical electrical parameters and is suitable for applications requiring enhanced thermal performance. Physical dimension differences are within typical PCB layout tolerances for through-hole components.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP102 and CT-20EX102 be used interchangeably with CT20P102?

A: Yes. Both parts maintain identical resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions as the original CT20P102.

Q: What is the difference between CT-20EP102 and CT-20EX102?

A: Both parts are manufactured by Nidec Components Corporation with identical electrical and mechanical specifications. The difference lies in the base product number designation (CT20EP versus CT20EX) and packaging format (both supplied in bulk). Selection between these parts depends on supplier availability and packaging requirements.

Q: Can 3006P-1-102 replace CT20P102 in all applications?

A: The 3006P-1-102 maintains all critical electrical parameters and is suitable for most applications. The increased power rating (0.75W versus 0.5W) provides additional thermal margin. Physical dimensions differ slightly (0.250" x 0.190" versus 0.252" x 0.197"), which may require verification for space-constrained PCB layouts. The part is supplied in tube packaging rather than bulk.

Q: What compliance differences exist between substitute options?

A: CT-20EP102 and CT-20EX102 are ROHS3 compliant, while the original CT20P102 and 3006P-1-102 are RoHS non-compliant. Selection depends on regulatory requirements for the end application.

Q: Are there inventory considerations for these substitutes?

A: CT-20EP102 has 1607 pieces in stock, CT-20EX102 has 1020 pieces in stock, and 3006P-1-102 has 3839 pieces in stock. The original CT20P102 has 620 pieces available as new original stock.
