ASF42RG Equivalent & Substitute Parts

Part Overview

The ASF42RG is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a 4PDT (four-pole double-throw) switch with a rated capacity of 0.4VA at 20V. This through-hole, right-angle mounted component features a screwdriver slot actuator and is designed for applications requiring reliable switching with shorting contact timing (make-before-break). The part maintains Active product status and is currently in stock with 753 units available.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same product series, allowing for interchangeability in circuit designs while accommodating variations in packaging, compliance certifications, or inventory availability.

Substitute Part Grouping Explanation

The ASF42RG and its identified substitute, part number 2-1825011-4, are classified as direct equivalents within the TE Connectivity ALCOSWITCH Switches ASF series. Substitution eligibility is determined by matching the following critical parameters:

Electrical Equivalence Criteria:

• Identical circuit configuration (4PDT)
• Identical contact timing specification (Shorting/MBB)
• Identical current rating (0.4VA AC/DC)
• Identical voltage ratings (20V AC and DC)
• Identical contact material and finish (Copper Alloy with Gold plating)

Mechanical Equivalence Criteria:

• Identical actuator type (Screwdriver Slot)
• Identical mounting configuration (Through Hole, Right Angle)
• Identical termination style (PC Pin)
• Identical switch travel distance (2.79mm)
• Identical operating force (950gf)

Performance Equivalence Criteria:

• Identical mechanical life rating (15,000 cycles)
• Identical electrical life rating (15,000 cycles)
• Identical operating temperature range (-40°C to 80°C)

The substitute part 2-1825011-4 maintains full functional and mechanical compatibility with ASF42RG, with the primary distinction being packaging format (Tube versus standard packaging) and RoHS3 compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both ASF42RG and 2-1825011-4 are Active products from TE Connectivity ALCOSWITCH Switches and maintain identical electrical and mechanical specifications across all critical parameters. Selection between these parts is determined by application-specific requirements:

Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9050, indicating identical export and tariff classification. The substitute relationship is bidirectional, allowing either part number to fulfill circuit design requirements without functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ASF42RG be directly replaced with 2-1825011-4 in existing circuit designs?

A: Yes. Both parts maintain identical electrical specifications (4PDT, 0.4VA, 20V AC/DC), mechanical configuration (through-hole right-angle mounting, PC pin termination), and performance characteristics (15,000 cycle life, 950gf operating force). Direct substitution is supported without circuit modification.

Q: What is the difference between ASF42RG and 2-1825011-4?

A: The primary differences are packaging format (standard versus tube) and RoHS certification status. ASF42RG uses standard packaging and carries "Not Applicable" RoHS status. Part 2-1825011-4 is supplied in tube packaging and is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Which part should be selected for RoHS-compliant applications?

A: Part 2-1825011-4 is ROHS3 compliant and is the appropriate selection for applications requiring RoHS certification. ASF42RG carries "Not Applicable" RoHS status and should not be used in designs with mandatory RoHS compliance requirements.

Q: Are there any compatibility issues with PCB assembly equipment?

A: No compatibility issues exist between the two parts. Both feature identical through-hole, right-angle mounting with PC pin termination. The tube packaging of 2-1825011-4 is compatible with standard automated pick-and-place equipment used in PCB assembly processes.

Q: What is the contact material specification for both parts?

A: Both ASF42RG and 2-1825011-4 feature copper alloy contacts with gold finish. This specification ensures consistent electrical performance and corrosion resistance across both part numbers.

Q: Is the operating temperature range identical for both parts?

A: Yes. Both parts operate across the identical temperature range of -40°C to 80°C, supporting equivalent thermal performance in diverse environmental conditions.

Q: What is the mechanical life expectancy for these switches?

A: Both parts are rated for 15,000 mechanical cycles and 15,000 electrical cycles, providing equivalent durability and operational longevity in switching applications.
