Switchcraft 50212L Slide Switch 4PDT 3A 125V Equivalent & Substitute Parts

Part Overview

The Switchcraft 50212L is a 4PDT (four-pole double-throw) slide switch rated for 3A AC at 125V and 500mA DC at 125V. This panel-mount switch features non-shorting (BBM) contact timing and solder lug termination. The 50212L is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50212L is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Contact timing specification (Non-Shorting BBM)
• Switch function (On-On)
• Current and voltage ratings (3A AC / 500mA DC at 125V AC/DC)
• Actuator type and length (Standard, 8.74mm)
• Contact material (Copper Alloy)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Operating temperature range (-20°C to 70°C)
• Actuator material (Thermoplastic)

Parts meeting all these parameters are classified as direct equivalents within the Switchcraft 50200 series.

Parameter Comparison

Engineering Selection Recommendations

The 50212LX serves as the direct functional equivalent to the obsolete 50212L. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the 50212LX is an active product with ROHS3 compliance, whereas the 50212L is obsolete and RoHS non-compliant.

For new designs or system replacements, the 50212LX is the appropriate selection. For legacy system maintenance where original specifications must be preserved, the 50212L remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 50212LX directly replace the 50212L in existing applications?

A: Yes. The 50212LX is electrically and mechanically identical to the 50212L across all functional parameters, including circuit configuration, current/voltage ratings, actuator specifications, and termination style. Physical form factor and mounting compatibility are preserved.

Q: What is the significance of the RoHS compliance difference?

A: The 50212L is RoHS non-compliant while the 50212LX is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the 50212LX is the mandated choice. For legacy systems without such constraints, both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: The 50212L is packaged as individual units, while the 50212LX is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Why is the 50212L classified as obsolete?

A: The 50212L has been superseded by the 50212LX within the Switchcraft 50200 series. The 50212LX provides equivalent functionality with improved regulatory compliance status.

Q: What parameters must remain constant for substitution validity?

A: All of the following must match: 4PDT circuit configuration, non-shorting BBM contact timing, on-on switch function, 3A AC and 500mA DC current ratings, 125V AC/DC voltage ratings, standard actuator type at 8.74mm length, copper alloy contacts, panel mount configuration, solder lug termination, and -20°C to 70°C operating temperature range.
