Switchcraft 46313LDR Equivalent & Substitute Parts

Part Overview

The Switchcraft 46313LDR is a slide switch with DP3T (double-pole, three-throw) circuit configuration, rated for 3A AC at 125V and 500mA DC at 125V. This component is designed for panel mount applications with solder lug termination. The 46313LDR is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The 46313LDRX qualifies as a direct substitute for the 46313LDR based on the following critical parameters:

• Circuit Configuration: Both parts maintain DP3T circuit with On-On-On switch function
• Electrical Ratings: Identical current ratings (3A AC / 500mA DC) and voltage ratings (125V AC / 125V DC)
• Contact Characteristics: Both use non-shorting (BBM) contact timing with copper alloy contacts and silver finish
• Mechanical Interface: Both feature panel mount configuration with solder lug termination and standard actuator type
• Operating Environment: Both rated for -20°C to 70°C operating temperature range
• Series Compatibility: Both belong to the Switchcraft 46300R series

The 46313LDRX is manufactured by the same supplier (Switchcraft Inc.) and maintains functional and electrical equivalence with the obsolete 46313LDR.

Parameter Comparison

Engineering Selection Recommendations

The 46313LDRX is the appropriate substitute for the obsolete 46313LDR. Both parts are electrically and mechanically equivalent across all critical parameters. The 46313LDRX offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and ongoing production requirements where regulatory compliance is necessary.

The minor difference in actuator length (8.74mm versus 8.60mm) falls within acceptable mechanical tolerances for panel mount applications and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 46313LDRX directly replace the 46313LDR in existing applications?

A: Yes. Both parts share identical electrical ratings (3A AC / 500mA DC at 125V), circuit configuration (DP3T On-On-On), contact characteristics (non-shorting, copper alloy with silver finish), and mechanical interface (panel mount, solder lug termination). The actuator length difference of 0.14mm is within acceptable mechanical tolerance for panel mount switches.

Q: What is the difference in packaging between these parts?

A: The 46313LDR is supplied in standard packaging, while the 46313LDRX is supplied in bulk packaging. Packaging format does not affect component functionality or electrical performance.

Q: Why is the 46313LDR classified as obsolete?

A: The 46313LDR has been discontinued by Switchcraft Inc. The 46313LDRX represents the active equivalent within the 46300R series and should be used for all new designs and replacement applications.

Q: Are there compliance differences between these parts?

A: The 46313LDR is RoHS non-compliant, while the 46313LDRX is ROHS3 compliant. For applications requiring regulatory compliance with RoHS directives, the 46313LDRX is the appropriate selection.

Q: Do both parts have the same switch travel distance?

A: Yes. Both the 46313LDR and 46313LDRX have a switch travel of 6.25mm, ensuring consistent mechanical operation in panel mount applications.
