CT6R103 Equivalent & Substitute Parts

Part Overview

The CT6R103 is a 10 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based trimmer features top adjustment with PC pin termination and is housed in a compact square package (7.00mm x 7.00mm). The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing maintenance and repair applications where this component is specified in existing designs.

Substitute Part Grouping Explanation

Substitution of the CT6R103 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CT-6ER103 qualifies as a direct equivalent based on the following criteria:

• Identical resistance value: 10 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 1
• Identical adjustment type: Top Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Through Hole
• Identical termination style: PC Pins
• Identical package dimensions: Square - 0.276" x 0.276" (7.00mm x 7.00mm)
• Identical moisture sensitivity level: 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The CT-6ER103 manufactured by Nidec Components Corporation is the direct equivalent substitute for the obsolete CT6R103. All electrical and mechanical parameters are identical, ensuring functional compatibility in existing circuit designs without modification.

The CT-6ER103 offers the additional advantage of active product status with ROHS3 compliance, providing improved availability and regulatory alignment for new production runs or long-term inventory planning. The RoHS non-compliance of the original CT6R103 should be considered when evaluating regulatory requirements for end applications.

Both parts share identical environmental specifications (MSL 1, REACH Unaffected, ECCN EAR99, HTSUS 8533.40.8050), confirming compatibility across supply chain and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can CT-6ER103 be used as a direct replacement for CT6R103 without circuit modification?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns) and mechanical specifications (package dimensions, termination style, mounting type) are identical, enabling direct substitution in existing designs.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The CT6R103 is obsolete and no longer manufactured. The CT-6ER103 is actively produced, ensuring reliable long-term availability for replacement and repair applications. For new designs, the CT-6ER103 is the recommended choice.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory and supply chain consideration rather than a functional parameter. The CT-6ER103's ROHS3 compliance provides regulatory alignment for applications subject to RoHS requirements. Both parts are electrically and mechanically equivalent.

Q: Are the package dimensions identical?

A: Yes. Both parts use the same square package format of 0.276" x 0.276" (7.00mm x 7.00mm), confirming PCB layout compatibility and mechanical fit.

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage and handling practices apply without special environmental controls.
