Coto Technology 9007-24-11 Equivalent & Substitute Parts

Part Overview

The Coto Technology 9007-24-11 is a reed relay classified as SPST (Single Pole Single Throw) configuration with a 24VDC coil, rated for 500 mA switching current. This relay features integrated diode protection and EMI shielding, with PC pin termination for through-hole mounting. The product is currently obsolete, necessitating identification of functionally compatible alternatives to maintain system reliability and procurement continuity. Substitute parts must maintain compatibility with the original coil voltage, contact form, and switching characteristics while considering available active alternatives in the market.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the Coto Technology 9007-24-11 is determined by the following mandatory electrical and mechanical parameters:

Primary Substitution Criteria:

• Coil Voltage: 24VDC (exact match required)
• Contact Form: SPST-NO (1 Form A) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Type: Non Latching (exact match required)

Secondary Electrical Compatibility Parameters:

• Contact Rating (Current): Must equal or exceed 500 mA
• Switching Voltage: Must support at least 200VAC and 200VDC maximum
• Must Operate Voltage: Must not exceed 18 VDC
• Must Release Voltage: Must not exceed 2 VDC
• Operate Time: Maximum 0.5 ms
• Release Time: Maximum 0.2 ms
• Operating Temperature Range: Must encompass -20°C to 85°C

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant acceptable
• Moisture Sensitivity Level: MSL 1 (Unlimited) required
• REACH Status: REACH Unaffected required
• ECCN: EAR99 required

The Sensata-Cynergy3 S1-2404DM meets all primary substitution criteria and demonstrates improved performance in secondary electrical parameters, including higher contact rating (1 A versus 500 mA) and extended switching voltage capability (300VAC/350VDC versus 200VAC/200VDC).

Parameter Comparison

Engineering Selection Recommendations

The Sensata-Cynergy3 S1-2404DM (base product S1-2404) constitutes the qualified substitute for the obsolete Coto Technology 9007-24-11. Both components satisfy identical coil voltage (24VDC), contact configuration (SPST-NO), mounting methodology (through-hole PC pin), and switching characteristics (non-latching). Compliance certifications align, with both products bearing RoHS compliance (ROHS3 represents current standard), REACH Unaffected status, and EAR99 classification. The S1-2404DM maintains current active product status, ensuring long-term procurement availability and technical support continuity. The substitute exhibits enhanced electrical performance margins, including doubled contact rating capacity (1 A versus 500 mA) and elevated switching voltage tolerance (300VAC/350VDC versus 200VAC/200VDC), providing design margin for industrial applications. Extended operating temperature range (-40°C to 85°C versus -20°C to 85°C) accommodates wider environmental conditions. Selection of the S1-2404DM for replacement applications eliminates obsolescence risk while maintaining functional and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the Sensata-Cynergy3 S1-2404DM directly replace the Coto Technology 9007-24-11 without circuit modification? A: Yes. Both relays share identical 24VDC coil voltage, SPST-NO contact configuration, through-hole PC pin termination, and non-latching coil type. The substitute meets all electrical compatibility requirements for the original application.

Q: What are the key differences in electrical performance between these relays? A: The S1-2404DM provides higher contact current rating (1 A versus 500 mA), extended switching voltage capability (300VAC/350VDC versus 200VAC/200VDC), lower must-operate voltage (16 VDC versus 18 VDC), and lower must-release voltage (1.25 VDC versus 2 VDC). Operate time and release time are slightly longer on the substitute (1 ms and 0.5 ms respectively, versus 0.5 ms and 0.2 ms on the original), and coil current increases from 12 mA to 24 mA.

Q: Are there packaging differences between these relays? A: The Coto 9007-24-11 is specified with hyphenated packaging designation (-), while the Sensata S1-2404DM is supplied in Bulk packaging. Both utilize identical through-hole PC pin mounting architecture suitable for standard PCB assembly processes.

Q: What is the significance of the coil resistance difference (2 kOhms versus 1 kOhms)? A: Coil resistance difference reflects the impedance characteristics of each relay design. The lower resistance in the S1-2404DM corresponds to higher coil current (24 mA versus 12 mA). Circuit designs must accommodate this difference in current draw when replacing the original relay; however, standard 24VDC supply designs typically support both coil current levels without modification.

Q: Why is product status important for component selection? A: The original Coto 9007-24-11 is classified as obsolete, indicating discontinued manufacturing and reduced procurement availability. The substitute Sensata S1-2404DM maintains active product status, ensuring continued stock availability, technical documentation support, and supply chain reliability for current and future production requirements.

Q: Are both relays compliant with environmental and export regulations? A: Yes. Both components are REACH Unaffected, EAR99 classified for export control purposes, and carry appropriate RoHS compliance certifications (original RoHS Compliant; substitute ROHS3 Compliant). Both are MSL 1 (Unlimited) rated, indicating unlimited shelf life without moisture exposure restrictions.

Q: Does the operating temperature range difference affect application suitability? A: The Sensata S1-2404DM provides extended lower temperature limit (-40°C versus -20°C), accommodating broader environmental conditions. Both relays support identical upper temperature limit (85°C). Applications operating within the original -20°C to 85°C range are fully compatible with either component.
