Key Parameters

Substitute Part Grouping Explanation

The 7101-05-1001 can be directly substituted with the Coto Technology 9007-05-01 based on matching critical electrical and mechanical parameters. The substitution is valid because both parts share identical specifications for contact form (SPST-NO), contact rating (500 mA), switching voltage (200 VAC, 200 VDC), coil voltage (5 VDC), operating temperature range (-20°C to 85°C), mounting type (Through Hole), termination style (PC Pin), and non-latching coil type with integrated diode feature.

The key parameters determining substitution eligibility are: Contact Form, Contact Rating, Switching Voltage, Coil Voltage, Operating Temperature Range, Mounting Type, Termination Style, and Coil Type.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 9007-05-01 is the direct substitute for the obsolete 7101-05-1001. The 9007-05-01 maintains active product status and offers improved compliance with ROHS3 certification. Both parts are REACH Unaffected and carry identical export classification (EAR99). The 9007-05-01 demonstrates superior performance characteristics with reduced coil current (10 mA versus 16.7 mA) and faster operate time (0.5 ms versus 1 ms), while maintaining all critical switching and operating parameters. Higher coil resistance in the substitute (500 Ohms versus 300 Ohms) reflects the efficiency improvement from lower current draw.

Frequently Asked Questions (FAQ)

Can the 9007-05-01 directly replace the 7101-05-1001 in existing designs?

Yes. Both parts are electrically equivalent for SPST-NO switching applications, sharing identical contact form, rating, switching voltage, and coil voltage specifications. Through-hole mounting and PC pin termination are identical, ensuring mechanical compatibility.

What are the performance differences between these parts?

The 9007-05-01 operates with lower coil current (10 mA versus 16.7 mA) and faster switching speed (0.5 ms operate time versus 1 ms). These represent engineering improvements in the 9000/Spartan series. Release time differs slightly (0.2 ms versus 0.1 ms) but remains within the response characteristics suitable for standard switching applications.

Why does the 9007-05-01 have higher coil resistance?

The 500 Ohms coil resistance in the 9007-05-01 is consistent with its reduced coil current requirement (10 mA at 5 VDC). This represents an optimized design in the later generation part, delivering equivalent switching performance with lower power consumption.

Are compliance and regulatory certifications equivalent?

Both parts are REACH Unaffected and classified as EAR99 for export purposes. The 9007-05-01 holds ROHS3 compliance compared to RoHS compliance of the obsolete part, reflecting updated regulatory standards. Both maintain unlimited moisture sensitivity level rating (MSL 1).

What packaging formats are available for the substitute?

The 9007-05-01 is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes, as this may differ from the original part's packaging format.
