Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7101-12-1001 is determined by equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 12 VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 500 mA minimum
• Switching voltage: 200 VAC, 200 VDC maximum or greater
• Mounting type: Through hole
• Termination style: PC pin
• Operating temperature range: -20°C to 85°C minimum
• Coil type: Non latching
• Integrated diode feature

The Coto Technology 9007-12-01 satisfies all mandatory matching parameters and qualifies as a direct substitute. Both components are manufactured by Coto Technology, share identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage limits, and maintain compatible through-hole PC pin termination.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 9007-12-01 is a qualified substitute for the obsolete 7101-12-1001 based on the following factors:

Product Status Consideration: The 9007-12-01 maintains active product status, ensuring ongoing availability and supply chain continuity compared to the discontinued 7101-12-1001.

Electrical Equivalence: Both relays operate at identical coil voltage (12 VDC), contact configuration (SPST-NO), current rating (500 mA), and switching voltage limits (200 VAC/200 VDC maximum). Functional compatibility is established across all primary electrical parameters.

Compliance Alignment: Both components maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory and export control consistency.

Physical Compatibility: Through-hole mounting type and PC pin termination style are identical, supporting direct board-level replacement without layout modifications.

Operational Differences: The 9007-12-01 exhibits faster operate time (0.5 ms versus 1 ms) and slightly higher coil current draw (12 mA versus 7.5 mA). These differences do not prevent substitution but represent performance variations within the same functional class.

Frequently Asked Questions (FAQ)

Q: Can the 9007-12-01 directly replace the 7101-12-1001 in existing circuit designs?

A: Yes. Both relays share identical coil voltage, contact configuration, current rating, and switching voltage specifications. Through-hole mounting and PC pin termination are compatible. Direct substitution is supported at the circuit level.

Q: What are the differences in coil current between these two relays?

A: The 7101-12-1001 draws 7.5 mA coil current, while the 9007-12-01 draws 12 mA. This difference reflects design variations between the 7000 and 9000 series but does not prevent substitution. Circuit designs must accommodate the higher current draw of the 9007-12-01.

Q: Are there timing differences between these relays?

A: Yes. The 9007-12-01 operates faster (0.5 ms operate time versus 1 ms) and has a slightly longer release time (0.2 ms versus 0.1 ms). Applications with strict timing requirements must evaluate these performance variations.

Q: What is the packaging difference between these parts?

A: The 7101-12-1001 packaging is not specified in available data. The 9007-12-01 is supplied in tube packaging. Packaging format may affect handling and storage procedures but does not impact electrical or mechanical compatibility.

Q: Are both relays RoHS compliant?

A: Yes. Both the 7101-12-1001 and 9007-12-01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the 7101-12-1001 classified as obsolete?

A: The 7101 series has been discontinued by Coto Technology. The 9000 series (Spartan) represents the current active product line for equivalent 12 VDC SPST-NO reed relay applications.
