Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST1-DC5V is determined by strict equivalence across the following electrical and mechanical parameters:

• Coil voltage: 5VDC
• Contact configuration: DPST-NO/NC (1 Form A, 1 Form B)
• Contact current rating: 8 A
• Switching voltage: 250VAC maximum
• Mounting type: Through hole
• Termination style: PC pin
• Coil resistance: 105 Ohms
• Operating temperature range: -40°C ~ 60°C

The ST1-DC5V-F meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics within the specified operating parameters.

The ST1-DC5V-F carries active product status, ensuring ongoing availability and supply chain support. The substitute part is ROHS3 compliant, meeting current environmental and regulatory requirements. Both parts maintain REACH unaffected status and EAR99 export classification.

Selection of the ST1-DC5V-F eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the ST1-DC5V-F be used as a direct replacement for the ST1-DC5V?

A: Yes. The ST1-DC5V-F is a direct equivalent substitute. All electrical parameters, mechanical dimensions, and functional characteristics are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the primary difference between these two parts?

A: The ST1-DC5V-F is the active production variant of the ST1-DC5V. The main part is obsolete, while the substitute maintains current manufacturing status. The ST1-DC5V-F is ROHS3 compliant, whereas the main part does not specify RoHS status.

Q: Are there packaging differences between the ST1-DC5V and ST1-DC5V-F?

A: The ST1-DC5V-F is supplied in box packaging, while the main part packaging is not specified. Both parts use identical PC pin termination and through-hole mounting, ensuring compatibility with standard PCB assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The ST1-DC5V-F is ROHS3 compliant and maintains REACH unaffected status. Both parts carry EAR99 export classification and HTSUS code 8536.41.0020.

Q: Are there inventory considerations when selecting between these parts?

A: The ST1-DC5V-F is actively stocked with 2950 pieces in inventory. The obsolete ST1-DC5V has limited remaining inventory of 2000 pieces. For new designs and long-term supply assurance, the ST1-DC5V-F is the recommended selection.
