CT10-1040-G4 Equivalent & Substitute Parts

Part Overview

The CT10-1040-G4 is a molded body reed switch manufactured by Coto Technology, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device. This component operates at 500mA with a maximum switching voltage of 140V AC / 200V DC and rated power of 10W. The product is currently obsolete, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for continued system operation and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the CT10-1040-G4 is determined by strict equivalence across the following critical electrical parameters: circuit configuration (SPST-NO), operate and release ranges (10 ~ 40AT and 3 ~ 35AT respectively), switching current capacity (500mA AC/DC), switching voltage ratings (140V AC / 200V DC), and rated power (10W). Mechanical compatibility requires matching mounting type (surface mount), termination style (gull wing), operating temperature range (-40°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected). Parts meeting these criteria maintain functional and physical interchangeability within the CT10 series molded body reed switch platform.

Parameter Comparison

Engineering Selection Recommendations

The CT10-1040-G2 represents a direct electrical and functional substitute for the obsolete CT10-1040-G4. Both components maintain identical switching characteristics, voltage ratings, and current capacity across the complete operating temperature range. The CT10-1040-G2 is currently in active production status, ensuring continued supply availability and manufacturing support. Both components carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected), confirming compatibility with current regulatory requirements. Mechanical differences in body dimensions exist between the two parts; however, both employ identical surface mount gull wing termination and maintain the same height above board specification critical to PCB layout integration.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for CT10-1040-G4 substitution? A: The substitute must maintain identical SPST-NO circuit configuration, 10 ~ 40AT operate range, 3 ~ 35AT release range, 500mA switching current, 140V AC / 200V DC switching voltage, and 10W rated power.

Q: Are there physical differences between CT10-1040-G4 and CT10-1040-G2? A: Yes. The CT10-1040-G4 body measures 0.505" L x 0.090" W x 0.095" H with 0.100" height above board. The CT10-1040-G2 body measures 0.458" L x 0.095" W x 0.115" H with 0.115" height above board. Both share identical overall length (0.770") and termination style, but PCB layout accommodation must account for the dimensional variation.

Q: Why is CT10-1040-G4 being replaced? A: The CT10-1040-G4 is obsolete product status. The CT10-1040-G2 provides full electrical equivalence while maintaining current manufacturing availability and support.

Q: Are compliance certifications equivalent between these parts? A: Both parts are ROHS3 Compliant and REACH Unaffected, confirming equivalent regulatory qualification for use in compliant assemblies.

Q: What is the operating temperature specification for both parts? A: Both CT10-1040-G4 and CT10-1040-G2 operate across the identical temperature range of -40°C to 125°C.
