Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7101-05-1100 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 5VDC
• Contact Form: SPST-NO (1 Form A)
• Contact Rating (Current): 500 mA
• Switching Voltage: 200VAC, 200VDC - Max
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -20°C ~ 85°C
• Coil Type: Non Latching
• Must Operate Voltage: 3.75 VDC
• Must Release Voltage: 0.4 VDC

The Coto Technology 9007-05-00 satisfies all mandatory matching parameters. This substitute is from the active 9000 series (Spartan line) and maintains full electrical and mechanical compatibility with the obsolete 7101-05-1100. Both components are manufactured by Coto Technology and share identical contact specifications, voltage ratings, and environmental operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 9007-05-00 is the direct substitute for the obsolete 7101-05-1100. Both components meet identical electrical specifications and environmental requirements. The 9007-05-00 offers the advantage of active product status, ensuring continued availability and manufacturing support.

The 9007-05-00 demonstrates improved performance characteristics in coil current efficiency (10 mA versus 16.7 mA) and faster switching response (0.5 ms operate time versus 1 ms). These improvements result from higher coil resistance (500 Ohms versus 300 Ohms) while maintaining identical voltage thresholds and release characteristics.

Both components maintain full RoHS and REACH compliance. The 9007-05-00 carries ROHS3 certification, representing the current regulatory standard. Packaging differs between the two parts: the 7101-05-1100 is supplied in bulk format, while the 9007-05-00 is supplied in tube packaging. This packaging difference does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 9007-05-00 directly replace the 7101-05-1100 in existing circuit designs?

A: Yes. Both relays share identical coil voltage (5VDC), contact configuration (SPST-NO), current rating (500 mA), switching voltage (200VAC/200VDC), operating temperature range (-20°C to 85°C), and activation thresholds (3.75 VDC operate, 0.4 VDC release). Through-hole PC pin termination is identical on both components.

Q: What are the differences between these two relays?

A: The primary differences are product status and performance characteristics. The 9007-05-00 is an active product with lower coil current draw (10 mA versus 16.7 mA), higher coil resistance (500 Ohms versus 300 Ohms), and faster switching times (0.5 ms operate versus 1 ms). The 7101-05-1100 is obsolete. Packaging differs: bulk versus tube.

Q: Are there any compliance or certification differences?

A: Both components are RoHS and REACH compliant. The 9007-05-00 carries ROHS3 certification, which is the current regulatory standard. The 7101-05-1100 carries RoHS Compliant status. Both are REACH Unaffected.

Q: Does the difference in coil current affect circuit design?

A: The 9007-05-00 requires less coil current (10 mA versus 16.7 mA) due to higher coil resistance. This may reduce power consumption in the drive circuit. Existing circuits designed for the 7101-05-1100 will operate the 9007-05-00 without modification, as the 5VDC coil voltage and activation thresholds remain identical.

Q: How do the switching times compare?

A: The 9007-05-00 operates faster (0.5 ms versus 1 ms) and has a slightly longer release time (0.2 ms versus 0.1 ms). For most applications, these timing differences are negligible. Applications with strict timing requirements should evaluate whether the faster operate time of the 9007-05-00 provides benefit or requires circuit adjustment.

Q: What is the impact of packaging format on component selection?

A: The 7101-05-1100 is supplied in bulk packaging, while the 9007-05-00 is supplied in tube packaging. Packaging format affects handling, storage, and assembly processes but does not affect electrical or mechanical performance. Component selection should be based on procurement and assembly requirements.
