RTAC30206B06AD50S Rotary Switch - Equivalent & Substitute Parts

Part Overview

The RTAC30206B06AD50S is a 6-position rotary switch manufactured by C&K, rated for 150mA at 60V AC/DC with a DP6T circuit configuration and panel mount installation. This component is classified as obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this legacy model is no longer readily procurable from primary distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RTAC30206B06AD50S is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: 6 positions, DP6T circuit, 150mA current rating, 60V AC/DC voltage rating
• Mechanical Configuration: Fixed index stops, non-shorting (BBM) contact timing, 30° angle of throw
• Physical Dimensions: Panel cutout diameter 10.20mm, actuator length 50.00mm
• Contact Properties: Brass material with silver finish
• Mounting Interface: Panel mount installation

The identified substitute part RTAP32S06M50NS maintains electrical and mechanical equivalence across all critical parameters. Differences exist only in actuator diameter specification (6mm vs 5.9mm), termination style (PC Pin vs Solder Lug), depth behind panel (12.60mm vs 18.70mm), and product compliance status. These differences represent design evolution within the RTA series rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The RTAP32S06M50NS represents the active production equivalent within the C&K RTA rotary switch family. Selection of this substitute is supported by:

Product Status: The RTAC30206B06AD50S is obsolete, while RTAP32S06M50NS maintains active product status with confirmed inventory availability (1086 units in stock versus 963 units for the obsolete model).

Regulatory Compliance: RTAP32S06M50NS achieves ROHS3 compliance, addressing modern environmental and regulatory requirements. The original RTAC30206B06AD50S does not meet current RoHS standards.

Electrical and Mechanical Equivalence: Both parts maintain identical electrical ratings (150mA, 60V AC/DC, DP6T), mechanical configuration (6 positions, 30° throw, non-shorting contact timing), and panel interface dimensions (10.20mm cutout).

Design Considerations: The substitute features a reduced depth behind panel (12.60mm versus 18.70mm), which may provide space advantages in compact enclosure designs. The termination transition from solder lug to PC pin requires PCB layout modification but enables standard through-hole assembly processes. The actuator diameter increase from 5.9mm to 6mm is within standard mechanical tolerance ranges for panel-mounted rotary switches.

Frequently Asked Questions (FAQ)

Q: Can RTAP32S06M50NS directly replace RTAC30206B06AD50S in existing designs?

A: Electrical and mechanical substitution is valid. The panel cutout diameter (10.20mm) and actuator length (50.00mm) are identical. PCB layout modification is required due to termination style change from solder lug to PC pin. The reduced depth behind panel (12.60mm) may require enclosure verification to confirm clearance compatibility.

Q: What is the significance of the actuator diameter difference (5.9mm vs 6mm)?

A: The 0.1mm difference falls within standard mechanical tolerances for rotary switch actuators. Both diameters are compatible with standard panel cutout dimensions (10.20mm). This difference does not affect functional performance or panel mounting compatibility.

Q: Why does the substitute have a slotted actuator while the original has a round actuator?

A: The slotted actuator design in RTAP32S06M50NS is a manufacturing refinement within the RTA series. Both configurations provide identical rotational and detent functionality. The slot accommodates standard screwdriver adjustment without affecting electrical performance.

Q: Are there compliance implications for switching from the obsolete to the active part?

A: Yes. RTAP32S06M50NS achieves ROHS3 compliance, meeting current environmental regulations. If your application or market requires RoHS compliance, this substitute is necessary. The original RTAC30206B06AD50S does not meet these standards.

Q: What assembly changes are required for the termination style transition?

A: The original uses solder lug termination (wire connection), while the substitute uses PC pin termination (PCB insertion). This requires PCB redesign to accommodate through-hole pin spacing and standard PCB assembly processes. Electrical performance remains unchanged.

Q: Is the through-hole mounting capability of the substitute a functional difference?

A: No. Both parts are panel mount components. The substitute's through-hole capability is an additional feature that does not affect panel mounting compatibility. Standard panel mount installation procedures apply to both parts.
