AH166261-A Equivalent & Substitute Parts

Part Overview

The AH166261-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with momentary on-function operation. This component is rated for 100mA at 125V AC and 30V DC, featuring a straight lever actuator with chassis mount configuration and solder lug termination. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and design continuity in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AH166261-A is determined by strict equivalence across the following core parameters: circuit configuration (SPDT), switch function (On-Momentary), current rating (100mA AC/DC), voltage ratings (125V AC / 30V DC), actuator type (straight lever), mounting type (chassis mount), and termination style (solder lug). The ABS1412513 meets all these mandatory criteria, establishing it as a functional equivalent. Variations in mechanical parameters such as operating force, pretravel, differential travel, and overtravel do not preclude substitution provided the electrical and mechanical interface specifications remain compatible with the original application design.

Parameter Comparison

Engineering Selection Recommendations

The ABS1412513 is the direct functional equivalent for the obsolete AH166261-A. Both components share identical electrical specifications (SPDT circuit, 100mA current rating, 125V AC / 30V DC voltage ratings) and mechanical interface requirements (straight lever actuator, chassis mount, solder lug termination). The ABS1412513 offers extended operational performance with 200,000 electrical cycles and 5,000,000 mechanical cycles compared to the original part's 100,000 and 500,000 cycles respectively. The substitute part operates across a wider temperature range (-40°C to 85°C versus -25°C to 85°C) and includes IP50 dust protection. The ABS1412513 maintains active product status and ROHS3 compliance, supporting long-term supply chain continuity. Both parts carry identical ECCN classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the ABS1412513 directly replace the AH166261-A in existing applications?

A: Yes. Both components share identical circuit configuration (SPDT), switch function (On-Momentary), current rating (100mA AC/DC), voltage ratings (125V AC / 30V DC), actuator type (straight lever), mounting type (chassis mount), and termination style (solder lug). These parameters define electrical and mechanical compatibility.

Q: What are the differences between these two parts?

A: The ABS1412513 provides enhanced performance specifications: extended electrical life (200,000 versus 100,000 cycles), extended mechanical life (5,000,000 versus 500,000 cycles), wider operating temperature range (-40°C to 85°C versus -25°C to 85°C), and IP50 dust protection. The ABS1412513 is currently active in production, whereas the AH166261-A is obsolete.

Q: Are there packaging differences?

A: The AH166261-A is specified with standard packaging, while the ABS1412513 is supplied in bulk packaging. Both use identical solder lug termination suitable for through-hole soldering applications.

Q: Do compliance certifications differ?

A: The ABS1412513 carries ROHS3 compliance certification. Both parts maintain identical ECCN classification (EAR99) and unlimited moisture sensitivity level (MSL 1).

Q: What is the basis for substitution eligibility?

A: Substitution is based on strict equivalence across mandatory electrical parameters (circuit type, current and voltage ratings, switch function) and mechanical interface specifications (actuator type, mounting configuration, termination style). Variations in operational life cycles and temperature range do not preclude substitution when these core parameters match.
