Substitute Part Grouping Explanation

Substitute parts for the 9091-12-00 must satisfy the following critical parameters to ensure functional compatibility:

• Contact Form: SPST-NO (1 Form A) configuration required
• Coil Voltage: 12VDC nominal operation
• Contact Rating: Minimum 500 mA current switching capability
• Switching Voltage: Support for 200VAC and 200VDC maximum levels
• Mounting Type: Through Hole termination with PC pins
• Packaging: Tube format for manufacturing compatibility
• Operational Characteristics: Non-latching coil type with sub-millisecond switching times
• Compliance: ROHS3 Compliant and REACH Unaffected status

The substitute part MS12-1A87-75L from Standex-Meder Electronics meets these fundamental requirements while maintaining Active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the Coto Technology 9091-12-00 and Standex-Meder Electronics MS12-1A87-75L maintain Active product status with ROHS3 compliance and REACH Unaffected classification. Selection between these parts depends on application-specific operating temperature requirements and system design margins.

The Coto 9091-12-00 provides an extended operating temperature range of -20°C to 85°C, suitable for applications requiring higher temperature performance. The Standex MS12-1A87-75L operates within -20°C to 70°C, with lower coil resistance (700 Ohms versus 1 kOhms) and faster release time (0.1 ms versus 0.3 ms), presenting alternative electrical characteristics for specific circuit requirements.

Both components share identical contact form, current rating, coil voltage, and switching voltage specifications, ensuring interchangeability within the core functional parameters.

Frequently Asked Questions (FAQ)

Q: Can the Standex MS12-1A87-75L directly replace the Coto 9091-12-00 in all applications?

A: Direct substitution is possible when operating temperatures remain within the MS12-1A87-75L limit of -20°C to 70°C. Applications requiring operation above 70°C must retain the Coto 9091-12-00 to maintain specified performance margins.

Q: What are the primary electrical differences between these parts?

A: The Standex part requires higher coil current (17.1 mA versus 12 mA) and has lower coil resistance (700 Ohms versus 1 kOhms). Must operate voltage differs at 8.4 VDC versus 9 VDC, and must release voltage is 1.8 VDC versus 1 VDC. These differences may affect circuit design parameters and power consumption calculations.

Q: Are both parts available in identical packaging formats?

A: Both parts are supplied in Tube packaging with Through Hole mounting and PC Pin termination, ensuring mechanical and electrical interface compatibility on printed circuit boards.

Q: What compliance certifications apply to both parts?

A: Both the Coto 9091-12-00 and Standex MS12-1A87-75L carry ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements for commercial and industrial applications.

Q: How do switching time characteristics compare?

A: Operate time is identical at 0.5 milliseconds for both parts. Release time differs significantly, with the Standex part releasing faster at 0.1 ms compared to the Coto part at 0.3 ms. This characteristic may influence timing-critical circuit designs.
