EDS09SNRSTR04Q Equivalent & Substitute Parts

Part Overview

The EDS09SNRSTR04Q is a 9-position DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This surface mount slide actuator switch is rated for 25mA at 24VDC and features a flush, recessed actuator level with gold-plated copper alloy contacts. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

The EDS08SNRSTU04Q is identified as a manufacturer-recommended substitute for the EDS09SNRSTR04Q. Substitution eligibility is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (SPST)
• Current rating (25mA)
• Voltage rating (24VDC)
• Contact material and finish (Copper Alloy, Gold)

Mechanical Compatibility Parameters:

• Actuator type (Slide, Standard)
• Actuator level (Flush, Recessed)
• Mounting type (Surface Mount)
• Termination style (J Lead)
• Pitch spacing (0.100" / 2.54mm)
• Height above board (0.136" / 3.45mm)
• Body material (Polyamide/Nylon)

Environmental and Compliance Parameters:

• Operating temperature range (-20°C to 85°C)
• Mechanical life (2,000 cycles)
• Electrical life (2,000 cycles)
• RoHS3 compliance

The primary difference between the main part and substitute is the number of positions: the EDS09SNRSTR04Q provides 9 positions, while the EDS08SNRSTU04Q provides 8 positions. This difference affects board length (22.76mm versus 20.22mm) but does not alter electrical or mechanical performance characteristics within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The EDS08SNRSTU04Q is the active equivalent substitute for the obsolete EDS09SNRSTR04Q. Both parts maintain identical electrical performance specifications, mechanical interface characteristics, and environmental operating parameters. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Selection of the EDS08SNRSTU04Q is appropriate for applications where the 8-position configuration meets functional requirements. Both parts are ROHS3 compliant and share equivalent contact reliability, actuator performance, and thermal operating ranges. The substitute part features defined moisture sensitivity level (MSL 1, Unlimited), providing additional environmental handling clarity for manufacturing processes.

The primary design consideration is the reduction from 9 to 8 switch positions, which results in a 2.54mm reduction in board length. PCB layout modifications are required to accommodate this dimensional change. All other mechanical and electrical interface parameters remain compatible.

Frequently Asked Questions (FAQ)

Q: Can the EDS08SNRSTU04Q directly replace the EDS09SNRSTR04Q without PCB modifications?

A: The EDS08SNRSTU04Q shares identical electrical ratings, actuator characteristics, and mounting specifications with the EDS09SNRSTR04Q. However, the reduction from 9 to 8 positions results in a 2.54mm shorter board length (20.22mm versus 22.76mm). PCB layout modifications are required to accommodate this dimensional difference.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts operate at 25mA, 24VDC with SPST circuit configuration, identical contact materials and finishes, and equivalent mechanical and electrical life ratings of 2,000 cycles.

Q: What is the difference in product status between these parts?

A: The EDS09SNRSTR04Q is classified as obsolete, while the EDS08SNRSTU04Q is active. Active status ensures continued manufacturing, availability, and supply chain support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and operate within the identical temperature range of -20°C to 85°C.

Q: What is the significance of the Moisture Sensitivity Level difference?

A: The EDS09SNRSTR04Q lists MSL as Not Applicable, while the EDS08SNRSTU04Q specifies MSL 1 (Unlimited). MSL 1 indicates the part has unlimited shelf life and does not require special moisture control during storage or handling.

Q: Are the actuator and mounting characteristics compatible?

A: Yes. Both parts feature identical slide (standard) actuators with flush, recessed levels, surface mount configuration, J lead termination, and 0.100" pitch spacing. Height above board is identical at 0.136" (3.45mm).

Q: What packaging differences exist between these parts?

A: The EDS09SNRSTR04Q packaging is listed as standard, while the EDS08SNRSTU04Q is supplied in tube packaging. This affects handling and storage but does not alter component performance.
