Switchcraft 46311LDR Equivalent & Substitute Parts

Part Overview

The Switchcraft 46311LDR is a slide switch with SP3T (single pole, three throw) configuration rated for 3A AC at 125V. This component features non-shorting contact timing, panel mount installation, and solder lug termination. The 46311LDR is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 46311LDR is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, Switchcraft 46311LDRX, maintains identical specifications for circuit configuration, current and voltage ratings, contact timing, switch function, mounting type, termination style, actuator dimensions, and operating temperature range. Both parts belong to the 46300R series and share the same contact material (copper alloy) and contact finish (silver).

The key substitution criteria are:

• SP3T circuit configuration with non-shorting contact timing
• 3A AC / 500mA DC current capacity
• 125V AC/DC voltage rating
• Panel mount with solder lug termination
• 8.74mm actuator length
• Operating temperature range of -20°C to 70°C

Parameter Comparison

Engineering Selection Recommendations

The 46311LDRX is the direct equivalent for the obsolete 46311LDR. Both parts are manufactured by Switchcraft Inc. within the same 46300R series and maintain complete electrical and mechanical compatibility. The primary distinction is product status: the 46311LDR is obsolete while the 46311LDRX is active and currently available.

An additional consideration is regulatory compliance. The 46311LDRX achieves ROHS3 compliance, whereas the 46311LDR is RoHS non-compliant. For applications subject to RoHS requirements, the 46311LDRX is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 46311LDRX directly replace the 46311LDR in existing designs?

A: Yes. The 46311LDRX maintains identical electrical ratings (3A AC / 500mA DC at 125V), circuit configuration (SP3T), contact timing (non-shorting), mounting type (panel mount), termination style (solder lug), and physical dimensions (8.74mm actuator length). No design modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 46311LDR is obsolete and RoHS non-compliant. The 46311LDRX is active, currently in production, and ROHS3 compliant. All functional and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel mount installation?

A: No. Both parts use identical panel mount configuration with solder lug termination and 8.74mm actuator length. Installation procedures and PCB layout requirements remain unchanged.

Q: Does the RoHS3 compliance of the 46311LDRX affect performance?

A: No. RoHS3 compliance reflects material composition standards and does not alter electrical performance, current capacity, voltage rating, or operating temperature range. Both parts operate identically within the specified -20°C to 70°C temperature range.

Q: What is the contact timing specification and why does it matter?

A: Both parts feature non-shorting contact timing (BBM - break before make). This ensures that the previous contact position breaks before the new contact position makes, preventing momentary short circuits during switching transitions. This specification is critical for circuit protection and signal integrity.
