ADE03 Equivalent & Substitute Parts

Part Overview

The ADE03 is a DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole single-throw (SPST) switch with 3 positions. This component is designed for through-hole mounting applications requiring low-current switching at 24VDC with a maximum current rating of 100mA. The ADE03 operates across a temperature range of -30°C to 85°C and features a slide actuator with raised level positioning.

The ADE03 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and repair requirements for systems utilizing this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ADE03 is based on electrical and mechanical parameter compatibility within the ADE series. The substitute part 1825057-2 maintains functional equivalence through the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (SPST)
• Matching number of positions (3)
• Same voltage rating (24VDC)
• Equivalent current handling capability

Mechanical Compatibility:

• Through-hole mounting type
• Standard slide actuator with raised level
• Identical pitch spacing (0.100" / 2.54mm)
• Same series designation (ADE)

Environmental Compatibility:

• Operating temperature range support
• Washable design capability
• Moisture sensitivity level (MSL 1 - Unlimited)

The substitute part 1825057-2 is derived from the same ADE series and maintains all functional parameters necessary for direct substitution in applications originally designed for the ADE03.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1825057-2 is the direct equivalent for the obsolete ADE03 based on the following engineering criteria:

Product Status Consideration: The ADE03 is obsolete and no longer in active production. The 1825057-2 is an active product from the same manufacturer and series, ensuring long-term component availability and supply chain continuity.

Compliance and Certification: The 1825057-2 achieves ROHS3 compliance, representing an improvement over the non-compliant ADE03. This upgrade supports regulatory requirements for new designs and manufacturing processes. Both parts maintain identical moisture sensitivity levels (MSL 1) and share the same ECCN and HTSUS classifications.

Functional Equivalence: All critical electrical and mechanical parameters are maintained between the ADE03 and 1825057-2. The identical circuit configuration, position count, actuator type, and mounting specifications ensure direct functional substitution without design modification.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging, which differs from the original bulk packaging. This packaging format is standard for active production components and supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1825057-2 be used as a direct replacement for the ADE03 in existing designs?

A: Yes. The 1825057-2 maintains identical electrical and mechanical specifications including circuit configuration (SPST), position count (3), actuator type (slide standard with raised level), and through-hole mounting. All functional parameters required for substitution are equivalent.

Q: What is the difference in RoHS compliance between these parts?

A: The ADE03 is RoHS non-compliant, while the 1825057-2 is ROHS3 compliant. This means the substitute part meets current regulatory requirements for hazardous substance restrictions. For new designs or manufacturing processes subject to RoHS regulations, the 1825057-2 is the appropriate selection.

Q: Are there packaging differences between the ADE03 and 1825057-2?

A: Yes. The ADE03 is supplied in bulk packaging, while the 1825057-2 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for active production components and is compatible with automated pick-and-place assembly equipment. Manual assembly processes can accommodate both packaging formats.

Q: Is the pitch spacing identical between these parts?

A: Yes. Both the ADE03 and 1825057-2 maintain a pitch of 0.100" (2.54mm), ensuring identical PCB footprint compatibility and mounting hole alignment.

Q: What is the moisture sensitivity level for the 1825057-2?

A: The 1825057-2 has a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life. This matches the ADE03 and requires no special moisture control handling during storage or assembly.

Q: Are both parts washable?

A: Yes. Both the ADE03 and 1825057-2 are washable, supporting standard PCB cleaning processes without component degradation.

Q: What is the current availability status of each part?

A: The ADE03 has 872 pieces in stock as new original inventory. The 1825057-2 has 661 pieces in stock as new original inventory. The 1825057-2, being an active product, offers superior long-term availability compared to the obsolete ADE03.
