Judco Manufacturing Inc. 50-0015-00 Pushbutton Switch SPST Equivalent & Substitute Parts

Part Overview

The Judco Manufacturing Inc. 50-0015-00 is a pushbutton switch with SPST (Single Pole Single Throw) circuit configuration, rated for 500mA DC at 12V. This component features a round plunger actuator with yellow cap, through-hole PC pin termination, and is designed for standard off-on switching applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50-0015-00 is determined by the following critical parameters: circuit configuration (SPST), mounting type (through hole), termination style (PC pin), and actuator type (round plunger). Substitute parts must maintain compatibility with these core mechanical and electrical interfaces.

The substitute parts are grouped into two categories based on electrical rating compatibility:

Category 1 - Direct Electrical Upgrade (Higher Current/Voltage Rating): Parts 40-4911-00 and 40-4681-00 maintain SPST circuit configuration with through-hole PC pin termination but offer increased current capacity (2A) and voltage rating (14V). These parts are suitable for applications where the original 50-0015-00 specifications are met or exceeded.

Category 2 - Circuit Variation (Different Switching Logic): Parts 40-4682-01 and 50-0041-00 represent alternative circuit configurations (SPST-NC and SPDT respectively) with different mounting or termination approaches. These are applicable only when the specific switching logic and mechanical interface requirements align with the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 40-4911-00

The 40-4911-00 is the recommended substitute for the 50-0015-00. Both parts maintain identical circuit configuration (SPST), switch function (Off-On), mounting type (through hole), and termination style (PC pin). The 40-4911-00 provides enhanced electrical ratings (2A at 14V versus 500mA at 12V), ensuring compatibility with the original application while offering increased operational margin. The 40-4911-00 is active in production status and carries ROHS3 compliance, providing long-term availability and regulatory alignment.

Secondary Substitute: 40-4681-00

The 40-4681-00 maintains through-hole PC pin termination and round plunger actuator but differs in circuit configuration (SPST-NO) and switch function (Off-Mom). This part is suitable only for applications where momentary switching logic is required. The 40-4681-00 is active in production and ROHS3 compliant.

Not Recommended for Direct Substitution:

The 40-4682-01 employs free-hanging mounting with wire leads termination, representing a significant mechanical departure from the through-hole PC pin interface of the 50-0015-00. This part is applicable only when the application design accommodates free-hanging configuration.

The 50-0041-00 features SPDT circuit configuration (three-position switching), which is functionally distinct from the SPST requirement. Although it shares the same series designation and through-hole PC pin termination, the circuit topology change requires application-level verification.

Frequently Asked Questions (FAQ)

Q: Can the 40-4911-00 directly replace the 50-0015-00 in existing designs?

A: Yes. The 40-4911-00 maintains identical circuit configuration (SPST), switch function (Off-On), mounting type (through hole), and termination style (PC pin). The higher electrical ratings (2A at 14V) ensure compatibility with applications originally specified for 500mA at 12V.

Q: What is the difference between SPST, SPST-NO, and SPST-NC configurations?

A: SPST (Single Pole Single Throw) is a basic on-off switch. SPST-NO (Normally Open) is a momentary switch that returns to open state when released. SPST-NC (Normally Closed) is a momentary switch that returns to closed state when released. The 50-0015-00 uses SPST for continuous on-off control.

Q: Why is the 40-4682-01 not recommended as a direct substitute?

A: The 40-4682-01 uses free-hanging mounting with wire leads termination, whereas the 50-0015-00 requires through-hole PC pin mounting. This mechanical incompatibility prevents direct substitution without PCB redesign.

Q: Are all substitute parts RoHS compliant?

A: The 50-0015-00 is RoHS Compliant. The active substitute parts (40-4911-00, 40-4681-00, 40-4682-01) are ROHS3 Compliant, representing an updated compliance standard. The 50-0041-00 is RoHS Compliant. All parts meet regulatory requirements for their respective production periods.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active parts are in current production with guaranteed availability. Obsolete parts are no longer manufactured. The 50-0015-00 is obsolete, necessitating substitution. The 40-4911-00, 40-4681-00, and 40-4682-01 are active, ensuring long-term supply chain reliability.

Q: Can the 50-0041-00 be used as a substitute?

A: The 50-0041-00 is a SPDT switch (three-position) rather than SPST (two-position). It is applicable only if the application requires three-position switching logic (On-Off-On). Direct substitution requires verification that the circuit design accommodates SPDT functionality.
