RTAC32S06M25FS Rotary Switch - Equivalent & Substitute Parts

Part Overview

The RTAC32S06M25FS is a 6-position rotary switch manufactured by C&K, featuring dual-pole, six-throw (DP6T) configuration with non-shorting contact timing. This panel-mount component is rated for 150mA at 60 VAC/DC and utilizes a flatted 6mm diameter actuator with 25mm length. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RTAC32S06M25FS is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: DP6T (dual pole, six throw)
• Contact timing: Non-shorting (BBM)
• Number of positions: 6
• Mounting type: Panel mount
• Termination style: Solder lug
• Angle of throw: 30°

Electrical Performance Parameters:

• Current rating must equal or exceed 150mA
• Voltage rating (AC and DC) must equal or exceed 60V

Mechanical Parameters:

• Actuator type: Flatted configuration
• Panel cutout compatibility: Circular mounting interface
• Depth behind panel: Must accommodate 18.70mm or less

The A20615RNZQ qualifies as a substitute based on matching circuit configuration (DP6T), contact timing (non-shorting BBM), position count (6), mounting type (panel mount), termination style (solder lug), and angle of throw (30°). The substitute exceeds electrical requirements with 2.5A AC / 350mA DC at 125V ratings. Mechanical compatibility is confirmed through flatted actuator design and circular panel cutout interface.

Parameter Comparison

Engineering Selection Recommendations

The A20615RNZQ serves as a functional substitute for the obsolete RTAC32S06M25FS based on equivalent circuit topology and electrical performance. Both components maintain RoHS compliance, with the A20615RNZQ meeting ROHS3 standards. The substitute provides enhanced electrical ratings (2.5A AC / 350mA DC at 125V) compared to the original specification (150mA at 60V), ensuring compatibility in applications operating within the original design envelope.

Mechanical integration requires consideration of two dimensional differences: the A20615RNZQ features a 6.35mm diameter actuator versus the original 6mm, and a 38.10mm actuator length compared to 25mm. Panel cutout diameter is slightly smaller (9.80mm versus 10.20mm). Depth behind panel increases from 18.70mm to 20.83mm. These variations must be evaluated against specific mechanical constraints of the target application.

Both components utilize identical contact timing (non-shorting BBM), angle of throw (30°), and termination methodology (solder lug), confirming functional equivalence for circuit-level applications.

Frequently Asked Questions (FAQ)

Q: Can the A20615RNZQ directly replace the RTAC32S06M25FS in existing designs?

A: Functional substitution is confirmed for circuit operation. The A20615RNZQ matches the critical electrical and switching characteristics (DP6T configuration, non-shorting contact timing, 6 positions, 30° throw angle). However, mechanical integration must be verified. The substitute has a longer actuator (38.10mm versus 25mm), larger diameter (6.35mm versus 6mm), and greater depth behind panel (20.83mm versus 18.70mm). Panel cutout diameter is slightly smaller (9.80mm versus 10.20mm). Mechanical fit within the enclosure must be confirmed before implementation.

Q: What are the key electrical differences between these components?

A: The A20615RNZQ provides higher electrical ratings: 2.5A AC and 350mA DC at 125V, compared to the original 150mA at 60V. Both AC and DC voltage ratings are doubled in the substitute. These enhanced ratings ensure the substitute operates safely in applications designed for the original component, as the substitute can handle higher power levels without exceeding its specifications.

Q: Are both components RoHS compliant?

A: Yes. The RTAC32S06M25FS is RoHS Compliant. The A20615RNZQ meets ROHS3 Compliant standards, representing a more recent compliance certification. Both components satisfy RoHS requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the significance of the contact material difference?

A: The original RTAC32S06M25FS uses brass contacts with silver finish. The A20615RNZQ uses solid silver (Ag) contacts with silver finish. Both configurations provide equivalent electrical performance for the specified current and voltage ratings. Silver contact material in the substitute may offer enhanced conductivity and contact reliability characteristics.

Q: How do the packaging and inventory considerations affect selection?

A: The RTAC32S06M25FS is obsolete with 743 pieces in stock. The A20615RNZQ is active production with 920 pieces available in tray packaging. For new designs or long-term production requirements, the A20615RNZQ represents the sustainable choice due to active product status and continued availability.

Q: What mechanical constraints should be evaluated before substitution?

A: Verify that the panel cavity accommodates the A20615RNZQ's larger actuator diameter (6.35mm) and longer length (38.10mm). Confirm that the enclosure depth allows for the increased behind-panel depth (20.83mm). The slightly smaller panel cutout diameter (9.80mm versus 10.20mm) may require panel modification. Actuator engagement and rotation clearance must be confirmed within the specific mechanical assembly.
