CSJ-38-70010 Equivalent & Substitute Parts

Part Overview

The CSJ-38-70010 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a DPDT (Double Pole Double Throw, 2 Form C) with a 120VAC coil and 10A contact rating. This relay features socketable mounting with an 8-pin octal termination style and is designed for switching applications up to 1200VA or 280W maximum load. The product is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and component replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSJ-38-70010 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 120VAC
• Contact form: DPDT (2 Form C)
• Contact rating: 10A minimum
• Termination style: 8-pin octal plug-in configuration
• Mounting type: Socketable
• Coil type: Non-latching

Compatible Operating Parameters:

• Switching voltage capability must support 120VAC minimum
• Maximum switching load must support 1200VA or 280W minimum
• Operate time of 25 ms or faster
• Operating temperature range must encompass the application environment

The IDEC RR2P-UAC120V relay meets all mandatory matching parameters and provides enhanced electrical specifications, including higher maximum switching voltage (240VAC vs. 120VAC) and improved temperature range capability (-25°C to 40°C vs. -10°C to 55°C). This substitute maintains functional equivalence while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RR2P-UAC120V from IDEC is a direct functional equivalent to the obsolete CSJ-38-70010. Both relays share identical coil voltage (120VAC), contact configuration (DPDT), current rating (10A), and termination style (8-pin octal socketable). The operate time of 25 ms is identical across both models.

The IDEC substitute offers significant advantages for new designs and replacement applications:

Compliance Status: The RR2P-UAC120V is ROHS3 compliant, whereas the CSJ-38-70010 is RoHS non-compliant. For applications subject to RoHS regulations, the IDEC relay is the appropriate selection.

Product Availability: The RR2P-UAC120V maintains active product status with 1,042 units in stock, compared to the obsolete CSJ-38-70010 status. This ensures long-term availability for production and field replacement requirements.

Electrical Performance: The RR2P-UAC120V provides enhanced maximum switching voltage capability (240VAC vs. 120VAC) and improved coil current specification (20.5 mA), offering greater operational margin in switching applications.

Certification: Both relays carry EAR99 ECCN classification and are suitable for equivalent regulatory environments.

For applications requiring the exact original specification, the CSJ-38-70010 remains available with 741 units in current inventory. However, for new designs, compliance-driven replacements, or long-term system support, the RR2P-UAC120V is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the RR2P-UAC120V directly replace the CSJ-38-70010 in existing sockets?

A: Yes. Both relays feature identical 8-pin octal socketable termination and mounting type. The RR2P-UAC120V is mechanically and electrically compatible with existing CSJ-38-70010 socket installations.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), maximum switching voltage (120VAC/28VDC vs. 240VAC/30VDC), and operating temperature range (-10°C to 55°C vs. -25°C to 40°C). All critical functional parameters—coil voltage, contact form, current rating, and operate time—are identical.

Q: Is the RR2P-UAC120V suitable for applications requiring RoHS compliance?

A: Yes. The RR2P-UAC120V is ROHS3 compliant, making it suitable for applications and markets with RoHS requirements. The CSJ-38-70010 is RoHS non-compliant.

Q: What is the coil current requirement for the RR2P-UAC120V?

A: The RR2P-UAC120V requires 20.5 mA coil current at 120VAC, with a coil resistance of 2.1 kOhms.

Q: Are both relays non-latching?

A: Yes. Both the CSJ-38-70010 and RR2P-UAC120V are non-latching relays, meaning they require continuous coil energization to maintain contact closure.

Q: What is the maximum switching load for the RR2P-UAC120V?

A: The maximum switching load specification for the RR2P-UAC120V is not provided in the available technical data. The CSJ-38-70010 supports 1200VA or 280W maximum switching load.

Q: Can these relays be used in temperature extremes?

A: The CSJ-38-70010 operates from -10°C to 55°C, while the RR2P-UAC120V operates from -25°C to 40°C. Application temperature requirements must fall within the selected relay's operating range.

Q: What contact material is used in the RR2P-UAC120V?

A: The RR2P-UAC120V uses silver (Ag) contact material. Contact material for the CSJ-38-70010 is not specified in available documentation.
