RTAC31S07M25FS Rotary Switch - Equivalent & Substitute Parts

Part Overview

The RTAC31S07M25FS is a 7-position single-pole rotary switch manufactured by C&K, designed for panel-mount applications with a 60 VAC/DC rating and 150mA current capacity. This component features non-shorting (BBM) contact timing, silver-plated brass contacts, and a flatted 6mm diameter actuator with 25mm length. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RTAC31S07M25FS is determined by the following critical parameters:

Functional Compatibility Requirements:

• Number of positions: 7 (fixed requirement)
• Circuit configuration: SP7T (single pole, 7 throw)
• Contact timing: Non-shorting (BBM)
• Mounting type: Panel mount
• Termination style: Solder lug
• Angle of throw: 30°

Electrical Compatibility Requirements:

• Current rating must equal or exceed 150mA
• Voltage rating (AC and DC) must equal or exceed 60V
• Contact material and finish must support equivalent electrical performance

Mechanical Compatibility Requirements:

• Actuator type: Flatted configuration
• Panel cutout dimensions must accommodate the switch body
• Depth behind panel must be compatible with enclosure design

The substitute part A10715RNZQ meets these criteria with enhanced electrical ratings (2.5A AC / 350mA DC at 125V), maintaining identical functional configuration while providing superior performance margins for the same mechanical interface class.

Engineering Selection Recommendations

Primary Substitute: A10715RNZQ

The A10715RNZQ is the qualified substitute for RTAC31S07M25FS applications. Selection is based on the following engineering factors:

Functional Equivalence: Both components provide identical 7-position SP7T switching configuration with non-shorting contact timing, panel-mount installation, and solder-lug termination. The mechanical interface (flatted actuator, 30° throw angle) is compatible.

Electrical Performance: The A10715RNZQ provides superior electrical ratings (2.5A AC / 350mA DC at 125V) compared to the original specification (150mA at 60V). This represents a performance upgrade suitable for applications requiring the original component's functionality.

Product Status and Availability: The RTAC31S07M25FS is obsolete with no ongoing manufacturing. The A10715RNZQ is an active product with confirmed inventory (941 pcs), ensuring long-term availability for production and service applications.

Compliance: Both components meet RoHS requirements. The A10715RNZQ carries ROHS3 compliance certification, meeting current regulatory standards.

Physical Integration: Panel cutout dimensions are compatible (9.80mm vs. 10.20mm). Verify that the increased depth behind panel (20.83mm vs. 18.70mm) accommodates the enclosure design.

Frequently Asked Questions (FAQ)

Q: Can A10715RNZQ directly replace RTAC31S07M25FS in existing designs?

A: Yes, for applications operating within the original electrical specifications (≤150mA, ≤60V). The A10715RNZQ maintains identical switching configuration, contact timing, mounting type, and termination style. Verify panel depth clearance (20.83mm required vs. 18.70mm original).

Q: What are the key differences between these two switches?

A: The A10715RNZQ provides higher electrical ratings (2.5A AC / 350mA DC at 125V vs. 150mA at 60V), uses silver contact material instead of brass, and features a slightly larger actuator diameter (6.35mm vs. 6mm). Both maintain identical functional configuration and mechanical interface class.

Q: Are there any mechanical compatibility concerns?

A: The panel cutout diameter is slightly smaller on the A10715RNZQ (9.80mm vs. 10.20mm), which is compatible. The depth behind panel increases from 18.70mm to 20.83mm. Verify that the enclosure provides sufficient depth clearance before installation.

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

A: The A10715RNZQ uses silver (Ag) contacts with silver finish, providing superior electrical conductivity and contact reliability compared to the brass contacts with silver finish on the RTAC31S07M25FS. This represents an improvement in electrical performance.

Q: Is the A10715RNZQ suitable for AC and DC applications?

A: Yes. The A10715RNZQ is rated for 2.5A AC and 350mA DC at 125V, supporting both AC and DC switching applications. The original RTAC31S07M25FS was rated for 150mA AC/DC at 60V.

Q: What packaging is available for the A10715RNZQ?

A: The A10715RNZQ is supplied in tray packaging, suitable for production assembly and service stock applications.

Q: Are both components RoHS compliant?

A: Yes. The RTAC31S07M25FS is RoHS Compliant. The A10715RNZQ is ROHS3 Compliant, meeting current regulatory standards for hazardous substance restrictions.
