CSL-38-40010 Equivalent & Substitute Parts

Part Overview

The CSL-38-40010 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a DPDT (2 Form C) relay with a 48VDC coil and 10A contact rating. This socketable, 8-pin octal relay is designed for switching applications up to 1200VA or 280W at maximum load. The part is currently classified as obsolete, making identification of equivalent substitute components necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSL-38-40010 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 48VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating (Current): 10 A
• Mounting Type: Socketable
• Termination Style: Plug In, 8 Pin (Octal)
• Coil Type: Non Latching

Compatible Operating Parameters:

• Operate Time: 25 ms (matching specification)
• Switching Voltage capability must meet or exceed the original specification

The IDEC RR2P-UDC48V relay meets all mandatory matching parameters and is therefore classified as a direct functional equivalent. Both relays share identical coil voltage, contact configuration, current rating, socketable mounting, octal termination, and non-latching coil type. The substitute part demonstrates enhanced switching voltage capability (240VAC, 30VDC maximum versus 120VAC, 28VDC maximum) and identical operate time, confirming compatibility for direct substitution in applications previously served by the CSL-38-40010.

Parameter Comparison

Engineering Selection Recommendations

The IDEC RR2P-UDC48V relay is the qualified substitute for the obsolete CSL-38-40010. Selection of this substitute is supported by the following engineering factors:

Functional Equivalence: All critical relay parameters match exactly, including coil voltage, contact configuration, current rating, socketable mounting, and octal termination. Both relays operate identically at 25 ms switching time with non-latching coil type.

Product Status: The CSL-38-40010 is classified as obsolete, whereas the RR2P-UDC48V is active in production. Selection of the active substitute ensures continued availability for maintenance and new applications.

Regulatory Compliance: The RR2P-UDC48V is ROHS3 compliant and REACH unaffected, providing superior compliance posture compared to the non-compliant original part. Both parts carry EAR99 ECCN classification.

Enhanced Specifications: The substitute demonstrates superior switching voltage capability (240VAC, 30VDC maximum versus 120VAC, 28VDC maximum), providing additional margin for applications operating at higher voltage levels.

Temperature Consideration: The original part operates across -10°C to 55°C, while the substitute operates across -25°C to 40°C. Applications requiring operation above 40°C require verification that the substitute meets the specific thermal requirements of the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the IDEC RR2P-UDC48V directly replace the TE Connectivity CSL-38-40010 in existing sockets?

A: Yes. Both relays feature identical 8-pin octal socketable termination and mounting type. The RR2P-UDC48V plugs directly into existing CSL-38-40010 sockets without modification.

Q: Are the electrical switching characteristics identical between these two relays?

A: The relays share identical coil voltage (48VDC), contact form (DPDT), current rating (10A), and operate time (25 ms). The substitute provides enhanced switching voltage capability (240VAC, 30VDC maximum versus 120VAC, 28VDC maximum), making it suitable for higher-voltage switching applications.

Q: What is the difference in operating temperature range between these parts?

A: The CSL-38-40010 operates from -10°C to 55°C, while the RR2P-UDC48V operates from -25°C to 40°C. Applications requiring operation above 40°C should be evaluated against the substitute's maximum temperature specification.

Q: Does the substitute meet modern compliance requirements?

A: Yes. The RR2P-UDC48V is ROHS3 compliant and REACH unaffected. The original CSL-38-40010 is RoHS non-compliant. The substitute provides improved regulatory compliance for new designs and updated systems.

Q: Are there any differences in coil specifications between these relays?

A: The RR2P-UDC48V specifies a coil current of 30 mA and coil resistance of 1.6 kOhms. The original part does not provide these specifications in the available data. Both relays feature non-latching coil type and 48VDC coil voltage.

Q: What is the inventory status of these parts?

A: The CSL-38-40010 has 880 pieces in stock as new original inventory. The RR2P-UDC48V has 847 pieces in stock as new original inventory. Both parts are available for immediate procurement.

Q: Can the RR2P-UDC48V be used in applications previously designed for the CSL-38-40010?

A: Yes, for applications operating within the substitute's temperature range (-25°C to 40°C) and voltage specifications. The identical electrical characteristics, socketable mounting, and octal termination ensure functional compatibility in existing circuit designs.
