CT10-1540-G2 Equivalent & Substitute Parts

Part Overview

The CT10-1540-G2 is a molded body reed switch manufactured by Coto Technology, configured as a single-pole single-throw normally-open (SPST-NO) device. This component is rated for 500mA switching current at 140V AC (200V DC) with a 10W power rating and operates across a temperature range of -40°C to 125°C. The CT10-1540-G2 is classified as obsolete, making identification of active equivalent alternatives necessary for new design implementations and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The CT10-1540-G4 qualifies as a direct substitute for the CT10-1540-G2 based on electrical and mechanical compatibility within the CT10 series. Substitution is valid when the following key parameters match:

• Circuit configuration: SPST-NO
• Switching current capacity: 500mA (AC/DC)
• Switching voltage ratings: 140V AC / 200V DC
• Power rating: 10W
• Operate range: 15 ~ 40AT
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 125°C
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

The CT10-1540-G4 shares all critical electrical parameters with the main part. Physical dimensions vary slightly in body size and height above board, but these differences do not affect electrical substitutability or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

The CT10-1540-G4 is a qualified substitute for the obsolete CT10-1540-G2. Both components share identical electrical specifications and compliance certifications (ROHS3 Compliant, MSL 1, REACH Unaffected, EAR99). The CT10-1540-G4 maintains active product status with confirmed inventory availability, ensuring supply chain continuity.

Design layout modifications may be required due to dimensional variations in body size and height above board. The CT10-1540-G4 features a slightly larger body length (12.83mm vs. 11.63mm) and reduced height above board (2.54mm vs. 2.92mm). These physical differences must be evaluated within the context of specific PCB layout constraints and mechanical clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CT10-1540-G4 directly replace the CT10-1540-G2 in existing circuits?

A: Yes, the CT10-1540-G4 is electrically equivalent. All switching parameters, power ratings, and voltage specifications are identical. PCB layout review is required due to minor dimensional differences.

Q: What are the key differences between these two parts?

A: The primary differences are product status (CT10-1540-G2 is obsolete; CT10-1540-G4 is active) and physical dimensions. Body length differs by 1.20mm, body width by 0.12mm, and height above board by 0.38mm.

Q: Are both parts RoHS compliant?

A: Yes, both CT10-1540-G2 and CT10-1540-G4 are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What operating conditions are supported by the substitute part?

A: The CT10-1540-G4 operates identically across -40°C to 125°C with 500mA switching capacity at 140V AC or 200V DC.

Q: Is PCB redesign necessary for substitution?

A: The substitute part requires PCB layout evaluation due to dimensional variation. The reduced height above board may provide improved layout flexibility, while the increased body length requires clearance verification.
