Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34ASP51B1M1RT is determined by the following mandatory parameters:

Mechanical Compatibility Requirements:

• Panel mount configuration with circular 6.35mm diameter cutout
• 1/4-40 bushing thread specification
• Solder lug termination style
• SPDT circuit topology
• On-Off-Mom switch function
• Operating temperature range -30°C to 85°C
• 40,000 cycle electrical life rating

Electrical Compatibility Considerations: Substitute parts identified in this reference maintain identical mechanical interfaces and circuit topology. Substitute parts feature elevated current ratings (5A) and voltage ratings (120V AC / 28V DC) compared to the main part (0.4VA / 20V). These higher ratings provide backward compatibility for the 34ASP51B1M1RT application envelope while enabling use in higher-power circuit designs.

Compliance and Certification: All substitute parts maintain RoHS3 compliance status. REACH status varies between substitute options and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

100SP5T1B1M1QEH (E-Switch Series 100): This substitute maintains identical actuator length (10.41mm) and mechanical interface specifications as the main part. The component features epoxy sealed terminals and ROHS3 compliance with REACH Unaffected status. Current rating of 5A and voltage rating of 120V AC / 28V DC provide increased electrical capacity. This part is suitable for direct mechanical and electrical substitution in applications where higher current handling is required or where component availability necessitates alternative sourcing.

7107SYZQE (C&K Series 7000): This substitute provides mechanical compatibility with actuator length of 10.67mm, representing a 0.26mm variance from the main part specification. Standard round actuator type matches the main part configuration. ROHS3 compliance is maintained; however, REACH Affected status requires evaluation against application regulatory requirements. Epoxy sealed terminals and 5A current rating support higher-power applications.

7107P3YZQE (C&K Series 7000): This substitute features a flat anti-rotation actuator type and increased actuator length of 11.43mm, representing a 1.02mm variance from the main part. This configuration provides enhanced anti-rotation characteristics for applications requiring actuator stability. ROHS3 compliance and REACH Affected status apply. Epoxy sealed terminals and 5A current rating are provided.

Compliance Basis for Selection: All substitute parts maintain Active product status and 40,000 cycle electrical life specification. Selection between substitute options should prioritize REACH compliance requirements for the target application geography. Actuator length variance should be evaluated against panel cutout clearance and user interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the 34ASP51B1M1RT be replaced with a higher-rated substitute part in a low-power application?

A: Yes. The substitute parts identified (100SP5T1B1M1QEH, 7107SYZQE, 7107P3YZQE) feature higher current and voltage ratings than the main part. These elevated ratings provide backward compatibility, meaning they can operate safely in applications designed for the 0.4VA / 20V specification of the 34ASP51B1M1RT. The mechanical interface (panel cutout, bushing thread, termination style) and circuit topology (SPDT, On-Off-Mom function) are identical across all parts.

Q: What is the significance of actuator length differences between substitute parts?

A: Actuator length affects the physical engagement depth with the panel and user interface feel. The main part specifies 10.41mm. The 100SP5T1B1M1QEH substitute matches this specification exactly. The 7107SYZQE variant is 10.67mm (0.26mm longer), and the 7107P3YZQE is 11.43mm (1.02mm longer). These differences must be evaluated against panel thickness and clearance requirements in the target application. Actuator type also varies: the 7107P3YZQE features flat anti-rotation design compared to standard round on other parts.

Q: Are there REACH compliance differences between substitute options?

A: Yes. The main part (34ASP51B1M1RT) and the E-Switch substitute (100SP5T1B1M1QEH) are both REACH Unaffected. Both C&K substitutes (7107SYZQE and 7107P3YZQE) are REACH Affected. Applications subject to REACH regulations in the European Union or equivalent jurisdictions must select parts with appropriate REACH status for the target market.

Q: Do all substitute parts feature epoxy sealed terminals?

A: The main part (34ASP51B1M1RT) does not specify epoxy sealed terminals. All three substitute parts (100SP5T1B1M1QEH, 7107SYZQE, 7107P3YZQE) feature epoxy sealed terminals. This enhancement provides improved environmental protection for solder lug connections and may offer benefits in applications with moisture or contamination exposure.

Q: What is the difference between RoHS and ROHS3 compliance?

A: The main part carries RoHS Compliant designation. All substitute parts carry ROHS3 Compliant designation. ROHS3 represents the current iteration of the Restriction of Hazardous Substances directive. Both designations indicate compliance with hazardous substance restrictions; ROHS3 reflects the most recent regulatory framework.

Q: Can the 7107P3YZQE flat anti-rotation actuator be used interchangeably with standard round actuators?

A: The flat anti-rotation actuator on the 7107P3YZQE provides enhanced resistance to rotational movement compared to the standard round actuators on other parts. Mechanical interchangeability depends on panel design and user interface requirements. Applications requiring actuator stability or anti-rotation characteristics may benefit from this design variant. Applications with standard round actuator engagement features should use parts with standard round actuators (34ASP51B1M1RT, 100SP5T1B1M1QEH, or 7107SYZQE).

Q: Are all parts available in the same packaging format?

A: The main part (34ASP51B1M1RT) is specified with packaging designation "-". All substitute parts are specified as Bulk packaging. Packaging format should be confirmed with component suppliers based on procurement volume and assembly requirements.
