Equivalent & Substitute Parts for Coto Technology 8061-05-101 Reed Relay

Part Overview

The Coto Technology 8061-05-101 is a surface mount reed relay with SPDT contact configuration rated for 250 mA at 5VDC coil voltage. This component is classified as obsolete, necessitating identification of active equivalent alternatives from the manufacturer's current product line. The 8061 series has been superseded by the 8L61 series, which maintains functional compatibility while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8061-05-101 is determined by strict equivalence across the following critical parameters:

Direct Substitution Criteria:

• Coil voltage matching (5VDC)
• Contact form configuration (SPDT)
• Contact current rating (250 mA minimum)
• Switching voltage capability (100VAC, 100VDC minimum)
• Mounting type (Surface Mount)
• Termination style (J Lead)
• Operating temperature range (-20°C ~ 85°C minimum)
• Electrostatic shield feature presence

The 8L61-05-101 satisfies all direct substitution criteria as an active product from the same manufacturer with identical electrical and mechanical specifications. The 8L61-12-101 is listed as an alternative but operates at 12VDC coil voltage and therefore requires circuit redesign; it is not a direct drop-in replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 8L61-05-101

The 8L61-05-101 is the direct equivalent for the obsolete 8061-05-101. This substitute provides:

• Identical electrical specifications across all critical parameters
• Active product status with ongoing manufacturer support
• Enhanced RoHS3 compliance versus RoHS compliance of the original
• Maintained REACH unaffected and EAR99 export classification
• Higher inventory availability (1961 units in stock versus 780 units for the obsolete part)
• Bulk packaging option for production environments

Alternative Consideration: 8L61-12-101

The 8L61-12-101 operates at 12VDC coil voltage and is not a direct substitute. Selection of this part requires circuit modification to accommodate the different coil voltage, increased coil resistance (500 Ohms versus 200 Ohms), and modified operating thresholds (9.6 VDC must operate, 1 VDC must release). This part is suitable only when 12VDC supply voltage is available in the application.

Frequently Asked Questions (FAQ)

Q: Can the 8L61-05-101 be used as a direct replacement for the 8061-05-101 without circuit modification?

A: Yes. The 8L61-05-101 maintains identical coil voltage (5VDC), contact configuration (SPDT), current ratings (250 mA), switching voltage capability (100VAC/100VDC), and all timing specifications. No circuit redesign is required.

Q: What is the difference between the 8L61-05-101 and 8L61-12-101?

A: The primary difference is coil voltage: 8L61-05-101 operates at 5VDC with 200 Ohm coil resistance, while 8L61-12-101 operates at 12VDC with 500 Ohm coil resistance. The 12V variant also has different operating thresholds (9.6 VDC must operate versus 3.8 VDC). Both maintain identical contact ratings and switching specifications.

Q: Why is the 8061-05-101 listed as obsolete?

A: The 8061 series has been superseded by the 8L series from Coto Technology. The 8L61 series provides equivalent functionality with improved compliance certifications and active product status.

Q: Are there packaging differences between the main part and substitute?

A: The 8061-05-101 is specified with dash packaging notation, while the 8L61-05-101 is available in bulk packaging. Both use identical J Lead termination style and surface mount configuration.

Q: What compliance certifications apply to the 8L61-05-101?

A: The 8L61-05-101 carries ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is 1 (unlimited), indicating no special handling requirements.

Q: Can the 8L61-05-101 operate in the same temperature range as the original part?

A: Yes. Both the 8061-05-101 and 8L61-05-101 operate across the -20°C to 85°C temperature range with identical timing characteristics (1 ms operate and release times).
