Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34CMDP31B1M2RT is determined by strict alignment with the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 4.95mm Dia
• Bushing thread must be 10-48
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Actuator length must be 9.40mm

Electrical Performance Parameters: The substitute part must meet or exceed the electrical ratings of the main part. A substitute with higher current rating (2A versus 0.4VA) and higher voltage ratings (120V AC / 28V DC versus 20V AC/DC) is acceptable, as it provides greater electrical capacity while maintaining functional compatibility.

Environmental and Operational Parameters: Operating temperature range and electrical life cycle specifications must be equivalent or superior to the main part specifications.

The C&K T203SHCQE qualifies as a substitute based on matching all mandatory compatibility parameters while providing enhanced electrical performance characteristics.

Engineering Selection Recommendations

Primary Part Selection: The 34CMDP31B1M2RT remains the preferred selection when available, as it is the specified component for the application and carries active production status with RoHS compliance certification.

Substitute Part Selection: The C&K T203SHCQE is an acceptable substitute when the primary part is unavailable. The substitute maintains all mechanical and functional compatibility parameters while providing superior electrical performance ratings. Both components are actively produced and carry appropriate compliance certifications (RoHS and REACH status). The T203SHCQE is packaged in trays, whereas the main part packaging is not specified in the provided data.

Compliance Considerations: Both parts carry EAR99 ECCN classification and identical HTSUS codes, indicating equivalent regulatory treatment. The T203SHCQE carries REACH Affected status, whereas the main part is REACH Unaffected; this distinction must be evaluated within the context of the end application and regional requirements.

Frequently Asked Questions (FAQ)

Q: Can the T203SHCQE be used as a direct replacement for the 34CMDP31B1M2RT?

A: Yes, the T203SHCQE is mechanically and functionally compatible. All critical parameters including circuit configuration (DPDT), switch function (On-Off-On), panel cutout dimensions (4.95mm circular), bushing thread (10-48), actuator specifications, and termination style (PC Pin) are identical. The substitute provides higher electrical ratings, which is acceptable for applications designed for the lower-rated main part.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Grayhill versus C&K), current rating (0.4VA versus 2A), voltage ratings (20V versus 120V AC / 28V DC), packaging format (unspecified versus tray), and REACH compliance status (unaffected versus affected). All functional and mechanical parameters are equivalent.

Q: Are there any electrical compatibility concerns when substituting the T203SHCQE?

A: No electrical compatibility concerns exist. The substitute part has higher electrical capacity than the main part. Applications designed for 0.4VA at 20V will operate within the T203SHCQE's specifications of 2A at 120V AC / 28V DC.

Q: What is the significance of the panel cutout dimensions and bushing thread specifications?

A: These parameters determine physical compatibility with the panel mounting location. Both parts share identical specifications (4.95mm circular cutout and 10-48 bushing thread), ensuring mechanical interchangeability without panel modification.

Q: How do the packaging differences affect component selection?

A: The main part packaging is not specified in the provided data. The T203SHCQE is supplied in tray packaging. Packaging format may affect handling, storage, and procurement processes but does not impact functional or electrical compatibility.

Q: What is the significance of the REACH status difference?

A: The main part is REACH Unaffected, while the substitute is REACH Affected. This distinction relates to chemical substance regulations in the European Union. Applications subject to REACH requirements must evaluate whether the substitute's REACH Affected status is acceptable within their regulatory framework.

Q: Are both parts suitable for the same operating temperature range?

A: Yes, both parts operate across the identical temperature range of -30°C to 85°C, ensuring thermal compatibility across all environmental conditions.

Q: What does the 30,000 cycle electrical life specification indicate?

A: This specification indicates the number of complete on-off switching cycles each part is rated to perform before potential degradation. Both parts carry identical specifications, ensuring equivalent durability and reliability.
