SE1DGPC Equivalent & Substitute Parts

Part Overview

The SE1DGPC is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) switch with a rated capacity of 0.4VA at 20V. This through-hole mounted component features non-shorting contact timing, gold-plated copper alloy contacts, and IP67 environmental sealing. The SE1DGPC is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the SE1DGPC are classified based on electrical and mechanical compatibility within the constraints of the provided parameters. The primary substitution criterion is functional equivalence: all substitute parts must maintain SPDT circuit configuration, through-hole mounting, and PC pin termination.

The SE1DGPC operates at 0.4VA and 20V maximum ratings. Substitute parts are grouped into two categories:

Direct Equivalent (1825032-1): This part maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), mounting type (through-hole), and termination style (PC pin). The primary distinction is product status: 1825032-1 is active and RoHS3 compliant, whereas SE1DGPC is obsolete and non-compliant.

Similar Equivalent (500ASSP1M2QE): This part shares SPDT configuration, through-hole mounting, and PC pin termination but operates at higher electrical ratings (3A, 120V AC / 28V DC). This part is suitable only for applications where the higher voltage and current capacity do not create design conflicts or where derating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

1825032-1 (Direct Equivalent): This part is the primary substitute for SE1DGPC applications. It maintains identical electrical specifications (0.4VA, 20V AC/DC), circuit topology (SPDT), and physical form factor (through-hole, PC pin termination). The 1825032-1 is active in production with RoHS3 compliance, addressing the obsolescence and regulatory status of the original SE1DGPC. This part is suitable for direct replacement in existing designs without circuit modification.

500ASSP1M2QE (Similar Equivalent): This part is applicable only when the higher electrical ratings (3A, 120V AC / 28V DC) and extended mechanical life (30,000 cycles versus 10,000 cycles) provide design advantages or when the application circuit can accommodate the higher capacity without adverse effects. The 500ASSP1M2QE uses silver contact finish rather than gold and provides epoxy-sealed terminals instead of IP67 sealing. This part is suitable for new designs or redesigns where the enhanced specifications are beneficial.

Both substitute parts maintain SPDT configuration, through-hole mounting, and PC pin termination, ensuring mechanical and electrical interface compatibility with existing PCB layouts designed for SE1DGPC.

Frequently Asked Questions (FAQ)

Q: Can 1825032-1 be used as a direct replacement for SE1DGPC?

A: Yes. The 1825032-1 maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), mounting type (through-hole), and termination style (PC pin). No circuit modification is required. The primary advantage is active product status and RoHS3 compliance.

Q: What are the limitations of using 500ASSP1M2QE as a substitute?

A: The 500ASSP1M2QE operates at higher electrical ratings (3A, 120V AC / 28V DC) and has different contact finish (silver versus gold) and environmental sealing (epoxy sealed terminals versus IP67). This part is suitable only for applications where these differences do not create design conflicts. The higher current and voltage capacity may introduce unintended circuit behavior if not properly managed in the application design.

Q: Are there packaging differences between these parts?

A: Yes. SE1DGPC is supplied in unspecified packaging, 1825032-1 is supplied in bulk packaging, and 500ASSP1M2QE is supplied in tray packaging. Packaging differences affect inventory management and component handling but do not affect electrical or mechanical performance.

Q: What is the difference in mechanical life between these parts?

A: SE1DGPC and 1825032-1 are rated for 10,000 mechanical cycles. The 500ASSP1M2QE is rated for 30,000 mechanical cycles. For applications requiring extended switch life, the 500ASSP1M2QE provides enhanced durability.

Q: Are all substitute parts RoHS compliant?

A: No. SE1DGPC is RoHS non-compliant. Both 1825032-1 and 500ASSP1M2QE are RoHS3 compliant. For applications subject to RoHS regulations, either substitute part is acceptable; the original SE1DGPC is not.

Q: What is the operating temperature range for each part?

A: SE1DGPC and 1825032-1 operate from -20°C to 80°C. The 500ASSP1M2QE operates from -30°C to 85°C, providing a wider temperature range suitable for more demanding environmental conditions.
