Substitute Part Grouping Explanation

Substitution of the 7101-05-1011 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Coil voltage: 5VDC
• Contact form: SPST-NO (1 Form A)
• Contact current rating: 500 mA minimum
• Switching voltage: 200VAC/200VDC maximum or greater
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Features: Diode and electrostatic shield protection
• Operating temperature range: -20°C to 85°C minimum

The Coto Technology 8L01-05-111 satisfies all mandatory matching criteria while offering improved electrical performance characteristics and active product status. Both components are manufactured by Coto Technology, ensuring design consistency and supply chain compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 8L01-05-111 is the direct functional equivalent for applications currently using the obsolete 7101-05-1011. Selection of the 8L01-05-111 is supported by the following factors:

Product Status: The 8L01-05-111 maintains active product status with established supply availability, whereas the 7101-05-1011 is obsolete and subject to inventory depletion.

Regulatory Compliance: Both components satisfy RoHS and REACH requirements. The 8L01-05-111 carries ROHS3 certification, representing current compliance standards. Both components are classified under ECCN EAR99 and HTSUS 8536.41.0030.

Electrical Equivalence: The 8L01-05-111 maintains identical coil voltage, contact form, current rating, and switching voltage specifications. The substitute exhibits lower coil current consumption (10 mA versus 16.7 mA), reducing power dissipation in driver circuits.

Mechanical Compatibility: Through-hole mounting and PC pin termination are identical, enabling direct board-level substitution without layout modification.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 8L01-05-111 directly replace the 7101-05-1011 in existing circuit designs?

A: Yes. The 8L01-05-111 maintains identical coil voltage (5VDC), contact configuration (SPST-NO), current rating (500 mA), switching voltage (200VAC/200VDC), mounting type (through hole), and termination style (PC pin). Physical footprint and electrical interface are compatible.

Q: What are the differences in operating characteristics between these two relays?

A: The 8L01-05-111 exhibits lower coil current (10 mA versus 16.7 mA), higher coil resistance (500 Ohms versus 300 Ohms), faster operate time (0.5 ms versus 1 ms), and slightly higher must-operate and must-release voltage thresholds. These differences represent performance improvements in the active design.

Q: Are there packaging differences between the 7101-05-1011 and 8L01-05-111?

A: The 7101-05-1011 is supplied with standard packaging, while the 8L01-05-111 is packaged in tube format. Both are through-hole components with identical PC pin termination, suitable for automated assembly processes.

Q: Do both relays meet current regulatory requirements?

A: Yes. Both components are RoHS compliant and REACH unaffected. The 8L01-05-111 carries ROHS3 certification, representing the current regulatory standard. Both are classified as EAR99 for export control purposes.

Q: What is the moisture sensitivity classification for these relays?

A: Both the 7101-05-1011 and 8L01-05-111 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints. These components do not require special moisture control during storage or handling.

Q: Why is the 7101-05-1011 listed as obsolete?

A: Obsolete status indicates the 7101-05-1011 is no longer in active production. The 8L01-05-111 represents the current active equivalent from Coto Technology, offering improved performance and assured long-term supply availability.
