ADF05 Equivalent & Substitute Parts

Part Overview

The ADF05 is a DIP slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole single-throw (SPST) switch with 5 positions. The switch is rated for 25mA at 24VDC and features a through-hole mounting design with gold-plated copper alloy contacts. The ADF05 is classified as an obsolete product, necessitating identification of active equivalent alternatives to support ongoing procurement and system maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ADF05 is based on electrical and mechanical parameter equivalence. The substitute part 1825002-7 maintains identical specifications across all critical functional parameters: SPST circuit configuration, 5-position count, 25mA current rating, 24VDC voltage rating, slide actuator type, through-hole mounting, PC pin termination, 0.100" pitch, copper alloy gold-plated contacts, PPS body material, and identical mechanical and electrical life ratings of 1,000 cycles.

The key parameters determining substitution eligibility are:

• Circuit type and position count
• Current and voltage ratings
• Actuator mechanism and actuation level
• Mounting and termination compatibility
• Contact material and finish specifications
• Physical dimensions and pitch
• Operating temperature range
• Lifecycle ratings

Parameter Comparison

Engineering Selection Recommendations

The part 1825002-7 is the direct functional equivalent of the obsolete ADF05. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical and mechanical specifications across all critical parameters. The 1825002-7 is currently in active production status with significantly higher inventory availability (6,177 pieces versus 918 pieces for the obsolete ADF05).

A key advantage of the 1825002-7 is its RoHS3 compliance status, compared to the non-compliant RoHS status of the ADF05. This compliance improvement aligns with current regulatory requirements for electronic component procurement in many jurisdictions.

The packaging differs between the two parts: the ADF05 is supplied in bulk packaging, while the 1825002-7 is supplied in tube packaging. This packaging difference does not affect electrical or mechanical compatibility and is a standard variation in component distribution formats.

For new designs and replacement applications, the 1825002-7 is the appropriate selection due to its active product status, improved regulatory compliance, and equivalent functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 1825002-7 be used as a direct replacement for the ADF05 in existing circuit designs?

A: Yes. The 1825002-7 is electrically and mechanically equivalent to the ADF05 across all specified parameters. Both components feature identical SPST circuit configuration, 5-position count, 25mA current rating, 24VDC voltage rating, through-hole mounting with PC pin termination, 0.100" pitch, and operating temperature range. Physical dimensions and contact specifications are identical, enabling direct substitution in existing PCB layouts.

Q: What is the significance of the RoHS3 compliance difference between these parts?

A: The ADF05 is RoHS non-compliant, while the 1825002-7 is RoHS3 compliant. RoHS3 compliance indicates the component meets current European Union Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements or for new procurement, the 1825002-7 is the appropriate selection.

Q: Does the packaging difference between bulk and tube affect component performance?

A: No. Packaging format (bulk versus tube) is a distribution and handling consideration only and does not affect electrical performance, mechanical characteristics, or functional compatibility. The tube packaging of the 1825002-7 may provide improved protection during storage and transportation.

Q: Are there any differences in contact material or finish between the ADF05 and 1825002-7?

A: No. Both components feature copper alloy contacts with gold plating, providing identical electrical conductivity and corrosion resistance characteristics.

Q: What is the mechanical and electrical life expectancy for the 1825002-7?

A: The 1825002-7 is rated for 1,000 mechanical cycles and 1,000 electrical cycles, identical to the ADF05 specification.

Q: Is the 1825002-7 available in higher quantities than the ADF05?

A: Yes. Current inventory for the 1825002-7 is 6,177 pieces, compared to 918 pieces for the obsolete ADF05, providing improved supply availability for procurement planning.
