Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 7301-05-1000 is a direct functional equivalent to the 7301-05-1100 for all electrical and mechanical applications. The 7301-05-1000 is currently in active production status, whereas the 7301-05-1100 is classified as obsolete.

Compliance Considerations:

The 7301-05-1000 carries ROHS3 compliance certification, which represents an enhanced RoHS compliance status compared to the RoHS Compliant designation of the 7301-05-1100. Both parts maintain REACH Unaffected status and identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).

Procurement Advantage:

The 7301-05-1000 is available in active inventory (1136 pieces) with bulk packaging options, whereas the 7301-05-1100 is obsolete with limited remaining stock (968 pieces). For new designs and ongoing production requirements, the 7301-05-1000 is the appropriate selection.

Electrical and Mechanical Compatibility:

All electrical parameters, including coil voltage, contact rating, switching voltage, coil current, and timing specifications, are identical between the two parts. Mechanical compatibility is confirmed through identical mounting type (through hole), termination style (PC pin), and operating temperature range (-20°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the 7301-05-1000 be used as a direct replacement for the 7301-05-1100 in existing designs?

A: Yes. The 7301-05-1000 is electrically and mechanically identical to the 7301-05-1100 across all specified parameters. Both parts share the same coil voltage (5VDC), contact form (SPST-NO), current rating (500 mA), coil resistance (175 Ohms), and timing characteristics. Through-hole mounting and PC pin termination are identical.

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

A: ROHS3 Compliant represents an updated RoHS compliance certification. Both designations indicate compliance with Restriction of Hazardous Substances regulations. The 7301-05-1000 carries the more current ROHS3 certification.

Q: Are there packaging differences between these parts?

A: The 7301-05-1100 is specified with standard packaging, while the 7301-05-1000 is available in bulk packaging. Both parts are functionally identical and suitable for through-hole PCB assembly.

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

A: The must operate voltage is 3.75 VDC and the must release voltage is 0.4 VDC. The nominal coil voltage is 5VDC. The switching contacts are rated for 500VAC or 500VDC maximum.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate within the temperature range of -20°C to 85°C. Applications requiring operation outside this range require alternative component selection.

Q: What is the switching speed of these relays?

A: The operate time is 1 millisecond and the release time is 0.1 milliseconds, providing fast switching response suitable for general-purpose relay applications.

Q: Are these parts RoHS and REACH compliant?

A: Yes. Both the 7301-05-1100 and 7301-05-1000 are RoHS compliant and REACH unaffected. The 7301-05-1000 carries the enhanced ROHS3 certification.
