CT20P103 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT20P103 is a 10 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. Manufactured by Vishay Beyschlag/Draloric/BC Components, this component features cermet resistive material and 15-turn adjustment resolution. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specification.

Substitute Part Grouping Explanation

Substitute parts for the CT20P103 are classified based on electrical and mechanical parameter alignment:

Direct Electrical Equivalents (Identical Specifications): CT-20EP103 and CT-20EX103 maintain all critical electrical parameters: 10 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 15-turn adjustment, cermet material, side adjustment, PC pin termination, and equivalent face dimensions. These parts are manufactured by Nidec Components Corporation and carry Active product status with RoHS3 compliance.

Manufacturer-Recommended Substitute (Enhanced Power Rating): The 3006P-1-103 from Bourns Inc. provides the same electrical core specifications (10 kOhm, ±10% tolerance, ±100ppm/°C, 15-turn, cermet, side adjustment, PC pins) but with increased power rating of 0.75W. Dimensional tolerance is within acceptable mechanical limits (0.250" x 0.190" versus 0.252" x 0.197"). This part is designated as manufacturer-recommended and maintains Active status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CT-20EP103 and CT-20EX103 are functionally identical to CT20P103 across all electrical and mechanical parameters. Both parts are manufactured by Nidec Components Corporation with Active product status and RoHS3 compliance. Selection between these two direct equivalents may be based on packaging preference (both supplied in Bulk) and inventory availability (CT-20EP103: 1197 pcs; CT-20EX103: 940 pcs).

For Enhanced Reliability: The 3006P-1-103 from Bourns Inc. offers increased power dissipation capability (0.75W versus 0.5W) while maintaining all core electrical specifications. This part is manufacturer-recommended and suitable for applications where thermal margin is beneficial. Dimensional variation is minimal and compatible with standard PC pin through-hole mounting. Note that this part carries RoHS non-compliant status.

Compliance Considerations: Applications requiring RoHS3 compliance should utilize CT-20EP103 or CT-20EX103. Applications with REACH compliance requirements should note that the 3006P-1-103 carries REACH Affected status, while CT20P103 and Nidec equivalents are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can CT-20EP103 and CT-20EX103 be used interchangeably with CT20P103?

A: Yes. Both parts maintain identical electrical specifications (10 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C, 15-turn, cermet, side adjustment) and mechanical dimensions (0.252" x 0.197" face). Both are Active products from Nidec Components Corporation with RoHS3 compliance.

Q: What is the difference between CT-20EP103 and CT-20EX103?

A: Both parts are electrically and mechanically identical. The difference lies in the base product number designation (CT20EP versus CT20EX) and inventory levels. Selection may be based on supplier availability and packaging preferences.

Q: Is the 3006P-1-103 a suitable substitute for CT20P103?

A: Yes, with the following considerations: The 3006P-1-103 maintains all core electrical parameters and adjustment characteristics. The primary difference is increased power rating (0.75W versus 0.5W), which provides additional thermal margin. Face dimensions vary slightly (0.250" x 0.190" versus 0.252" x 0.197") but remain compatible with standard through-hole PC pin mounting. The part is manufacturer-recommended and carries Active status.

Q: Are there compliance differences between substitute options?

A: Yes. CT-20EP103 and CT-20EX103 are RoHS3 compliant and REACH Unaffected. The 3006P-1-103 is RoHS non-compliant and REACH Affected. Application compliance requirements should guide selection.

Q: What packaging formats are available for these substitutes?

A: CT-20EP103 and CT-20EX103 are supplied in Bulk packaging. The 3006P-1-103 is supplied in Tube packaging. Packaging selection may impact handling, storage, and assembly processes.
