Substitute Part Grouping Explanation

Substitution eligibility for the 34CMSP32B4M2RT is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish substitution validity:

Critical Parameters (Must Match Exactly):

  • Circuit configuration must be SPDT
  • Current rating must be 0.4VA for both AC and DC
  • Voltage rating must be 20V for both AC and DC
  • Switch function must be On-Off-On
  • Mounting type must be Through Hole
  • Termination style must be PC Pin

Important Parameters (Must Match or Exceed):

  • Actuator type must be Standard Round
  • Operating temperature range must encompass -30°C to 85°C
  • Electrical life must be 30,000 cycles or greater
  • RoHS compliance status must be ROHS3 or equivalent

The substitute part T103MH9CBE from C&K meets all critical and important parameters, establishing it as a valid equivalent for the 34CMSP32B4M2RT.

Engineering Selection Recommendations

Both the 34CMSP32B4M2RT and T103MH9CBE are active production parts with ROHS3 compliance, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on the following factors:

34CMSP32B4M2RT (Grayhill Inc.):

  • Primary choice when Grayhill supply chain is preferred
  • Bulk packaging suitable for high-volume manufacturing
  • 849 units currently in stock
  • REACH Unaffected status

T103MH9CBE (C&K):

  • Alternative source when Grayhill availability is constrained
  • Tray packaging suitable for smaller lot sizes or kit assembly
  • 1183 units currently in stock
  • REACH Affected status requires compliance verification for specific end-use applications

Both parts are electrically and mechanically equivalent for SPDT on-off-on switching at 0.4VA, 20V ratings. The 0.11mm difference in actuator length (5.33mm vs 5.44mm) is within standard mechanical tolerances and does not affect functional compatibility in standard through-hole panel mounting applications.

Frequently Asked Questions (FAQ)

Q: Can T103MH9CBE be used as a direct replacement for 34CMSP32B4M2RT in existing designs?

A: Yes. Both parts meet identical electrical specifications (SPDT, 0.4VA, 20V AC/DC, on-off-on function) and mechanical requirements (through-hole mounting, PC pin termination, standard round actuator). The actuator length difference of 0.11mm is within standard manufacturing tolerances and does not affect panel mounting compatibility.

Q: What is the significance of the different packaging formats (Bulk vs. Tray)?

A: Packaging affects handling and inventory management. Bulk packaging is optimized for high-volume production runs, while tray packaging is suitable for smaller quantities and kit assembly. Both formats contain the same electrical and mechanical components. Packaging selection should align with manufacturing process requirements and inventory management practices.

Q: Are there any compliance differences between these two parts?

A: Both parts are ROHS3 compliant and rated for the same operating temperature range (-30°C to 85°C). The T103MH9CBE is marked as REACH Affected, while the 34CMSP32B4M2RT is REACH Unaffected. Applications subject to REACH regulations should verify compliance requirements with the specific end-use market before selecting the C&K part.

Q: Do both parts have the same electrical life rating?

A: Yes. Both the 34CMSP32B4M2RT and T103MH9CBE are rated for 30,000 electrical cycles, ensuring equivalent reliability and service life in on-off-on switching applications.

Q: What factors should determine which part to order?

A: Selection should be based on: (1) current supplier availability and lead times, (2) packaging requirements for your manufacturing process, (3) inventory levels and procurement volume, (4) compliance requirements specific to your end-use application (particularly REACH status), and (5) cost considerations. Both parts are functionally equivalent for the specified electrical and mechanical parameters.
