Frequently Asked Questions (FAQ)

Q: Can KUP-5A55-24 be used as a direct replacement for KUP-5AT5-24?

A: Yes. The KUP-5A55-24 is a parametric equivalent with identical coil voltage (24VAC), contact form (SPDT), current rating (10A), switching voltage (240VAC max), mounting type (Chassis Mount), termination style (Quick Connect - 0.187"), operating temperature range (-45°C ~ 55°C), and all other critical electrical and mechanical parameters. Direct substitution is supported without circuit modification.

Q: Are there differences in packaging or MSL ratings between these parts?

A: Both parts are supplied in Bulk packaging. The KUP-5AT5-24 carries MSL rating of 1 (Unlimited), while KUP-5A55-24 lists MSL as Not Applicable. This difference does not affect substitution compatibility for standard applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in coil voltage (24VAC), contact form (SPDT 1 Form C), contact current rating (10A), switching voltage capability (240VAC max), mounting configuration (Chassis Mount), termination style (Quick Connect - 0.187"), operating temperature range (-45°C ~ 55°C), contact material (Silver Cadmium Oxide), coil type (Non Latching), and coil insulation class (Class B).

Q: Do both parts carry the same regulatory compliance?

A: Yes. Both KUP-5AT5-24 and KUP-5A55-24 are ROHS3 compliant, carry EAR99 ECCN classification, and share HTSUS code 8536.41.0050. Both maintain Active product status.

Q: What is the operating voltage range for these relays?

A: The coil must operate at 24VAC with a minimum operating voltage of 20.4VAC. The contacts support switching of loads up to 240VAC maximum. Coil current consumption is 84mA with coil resistance of 85 Ohms.

Q: What are the switching time specifications?

A: Operate time is 15 milliseconds and release time is 10 milliseconds for both parts. These timing parameters are identical across the substitution pair.
