CT-26-6A Equivalent & Substitute Parts

Part Overview

The CT-26-6A is a 10-turn concentric dial scale manufactured by Bourns Inc. with a 0.250" (6.35mm) shaft size and plastic scale construction. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing applications and new designs requiring similar functionality.

The CT-26-6A serves as a precision dial indicator for multi-turn potentiometers and similar rotational measurement applications. Due to its obsolete status, identifying compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-26-6A are qualified based on the following critical parameters:

• Shaft Size: All substitutes maintain the 0.250" (6.35mm) shaft diameter, ensuring mechanical compatibility with existing potentiometer shafts and mounting interfaces.
• Manufacturer: All substitutes are manufactured by Bourns Inc., maintaining design consistency and quality standards.
• Regulatory Compliance: All substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring environmental and regulatory compatibility.
• Scale Construction: Substitute parts feature metal scale construction rather than plastic, providing enhanced durability and precision in dial indication.
• Number of Turns: Substitute parts provide 15-turn capability, offering extended resolution compared to the 10-turn original specification.

The substitutes (H-22-6A, H-23-6A, H-516-6A) are all active products with confirmed inventory availability, addressing the supply discontinuation of the CT-26-6A.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (H-22-6A, H-23-6A, H-516-6A) meet the regulatory and compliance requirements of the CT-26-6A. Selection among these alternatives should be based on:

Product Status: All substitutes are active products with confirmed ongoing manufacturing and supply availability, eliminating obsolescence risk.

Compliance Alignment: All substitutes maintain identical RoHS3, REACH, and MSL certifications, ensuring regulatory compatibility in existing applications.

Inventory Availability: H-516-6A offers the highest inventory level (68,200 pcs), providing maximum supply security. H-22-6A and H-23-6A provide intermediate availability (2,350 and 1,102 pcs respectively).

Mechanical Compatibility: The 0.250" (6.35mm) shaft size is preserved across all substitutes, ensuring direct mechanical fit with existing potentiometer assemblies and mounting hardware.

Frequently Asked Questions (FAQ)

Q: Can H-22-6A, H-23-6A, or H-516-6A be used as direct replacements for CT-26-6A?

A: Yes. All three parts share the critical mechanical parameter (0.250" shaft size), regulatory compliance profile (ROHS3, REACH unaffected, MSL 1), and manufacturer origin (Bourns Inc.). The primary difference is the increase from 10 turns to 15 turns and scale material change from plastic to metal, which enhances durability and measurement resolution.

Q: What is the difference between H-22-6A, H-23-6A, and H-516-6A?

A: All three parts are functionally equivalent with identical shaft size (0.250"), turn count (15), scale type (metal), and compliance ratings. The differences are in packaging format (Box for H-22-6A and H-23-6A, Bulk for H-516-6A) and inventory availability. H-516-6A is available in significantly higher quantities.

Q: Does the change from 10 turns to 15 turns affect compatibility?

A: The increased turn count provides extended measurement range and finer resolution. Mechanical compatibility with the 0.250" shaft is maintained. Applications requiring the specific 10-turn range should evaluate whether the 15-turn capability introduces any functional constraints.

Q: Are all substitutes RoHS3 compliant?

A: Yes. CT-26-6A and all three substitute parts (H-22-6A, H-23-6A, H-516-6A) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute offers the best supply security?

A: H-516-6A provides the highest inventory level at 68,200 pcs, offering maximum supply continuity for high-volume applications and long-term availability assurance.
