Switchcraft 913 SPDT Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The Switchcraft 913 is a panel-mount pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 250mA at 125V AC and 48V DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The 913 series features a standard round button actuator with solder lug termination, suitable for front panel mounting applications.

Substitute Part Grouping Explanation

Substitute parts for the Switchcraft 913 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (913X): Maintains identical electrical ratings (250mA, 125V AC, 48V DC), circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Front), actuator type (Round, Button), and termination style (Solder Lug). The 913X differs only in product status (Active vs. Obsolete) and RoHS compliance level, making it a direct functional replacement.

Similar Substitute (1PB4): Shares the same circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Front), actuator type (Round, Button), and termination style (Solder Lug). However, the 1PB4 features higher electrical ratings (5A current, 250V AC, 30V DC) and is manufactured by Honeywell Sensing and Productivity Solutions. This part is suitable for applications where the 913's electrical specifications are not limiting factors and higher current capacity is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The Switchcraft 913X is the primary substitute for the obsolete 913 model. Both parts maintain identical electrical specifications and mechanical form factors. The 913X offers the advantage of active product status and ROHS3 compliance, making it suitable for new designs and systems requiring regulatory compliance.

For Higher Current Applications: The Honeywell 1PB4 serves as an alternative where circuit design permits higher current ratings (5A vs. 250mA). This part is appropriate for applications where the 913's current limitation is not a constraint and the higher voltage rating (250V AC) provides additional design margin. The 1PB4 is RoHS compliant and maintains active product status.

Compliance Considerations: Both substitute parts offer improved compliance profiles compared to the obsolete 913. The 913X provides ROHS3 compliance while maintaining identical electrical ratings. The 1PB4 provides RoHS compliance with enhanced electrical specifications. Selection should account for system-level regulatory requirements and design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 913X be used as a direct drop-in replacement for the 913? A: Yes. The 913X maintains identical electrical ratings (250mA, 125V AC, 48V DC), circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Front), actuator type (Round, Button), and termination style (Solder Lug). No circuit modifications are required.

Q: What are the key differences between the 913 and 913X? A: The primary differences are product status (Obsolete vs. Active) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: When should the Honeywell 1PB4 be selected instead of the 913X? A: The 1PB4 should be selected when circuit design permits higher current ratings (5A vs. 250mA) or when the higher AC voltage rating (250V vs. 125V) provides beneficial design margin. Both parts share identical circuit configuration, switch function, mounting type, and termination style.

Q: Are there packaging differences between these parts? A: The 913 is packaged in standard format, while both the 913X and 1PB4 are supplied in bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Do all three parts have the same panel mount footprint? A: All three parts feature Panel Mount, Front mounting type with Round Button actuators and Solder Lug termination. Mechanical compatibility is maintained across all three options.

Q: What compliance certifications apply to each part? A: The 913 is RoHS non-compliant and REACH unaffected. The 913X is ROHS3 compliant and REACH unaffected. The 1PB4 is RoHS compliant and REACH unaffected. All three share the same ECCN (EAR99) and HTSUS classification (8536.50.9031).
