PHA6UOA Equivalent & Substitute Parts

Part Overview

The PHA6UOA is a 6PDT pushbutton switch manufactured by C&K, designed for through-hole, right-angle mounting applications. This component features a 0.1A DC current rating at 30V, with a plunger actuator and white cap, sealed construction, and PC pin termination. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHA6UOA is determined by strict alignment with the following core parameters: 6PDT circuit configuration, on-momentary switch function, through-hole right-angle mounting, plunger actuator with cap, and PC pin termination. The primary constraint is the 100mA DC current rating at 30V DC. Substitute parts must maintain these electrical and mechanical specifications to ensure direct compatibility without circuit redesign.

Two substitute parts meet these criteria:

PBH6UOANAGX (E-Switch): Matches all core parameters including 6PDT configuration, 100mA DC at 30V, on-momentary function, through-hole right-angle mounting, plunger actuator, and PC pin termination. This part is currently active in production.

FLT6UOATB (C&K): Maintains 6PDT configuration, on-momentary function, and through-hole right-angle mounting. However, this part features enhanced current rating (500mA AC/DC), extended voltage capability (125V AC), and dual termination options (PC Pin and Solder Lug). While electrically superior, it remains mechanically compatible for direct substitution in the same mounting footprint.

Parameter Comparison

Engineering Selection Recommendations

PBH6UOANAGX (E-Switch): This substitute provides direct electrical and mechanical equivalence to the PHA6UOA. Both parts share identical current and voltage ratings (100mA DC at 30V), matching circuit configuration, and identical termination style. The PBH6UOANAGX is currently in active production with ROHS3 compliance, making it the preferred direct replacement for applications requiring exact parameter matching. The extended operating temperature range (-20°C to 70°C versus -10°C to 60°C) and increased mechanical life (30,000 cycles versus unlimited specification) provide additional operational margin.

FLT6UOATB (C&K): This substitute maintains mechanical compatibility and core circuit functionality while offering enhanced electrical performance. The 500mA AC/DC current rating and 125V AC capability exceed the original specification, providing design flexibility for future upgrades or higher-load applications. The dual termination options (PC Pin and Solder Lug) accommodate different assembly methods. The significantly extended electrical life (100,000 cycles) and wider operating temperature range (-40°C to 70°C) support demanding environments. This part is suitable for applications where performance headroom is beneficial, though it represents a specification upgrade rather than a direct equivalent.

Both substitute parts maintain RoHS and REACH compliance, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can PBH6UOANAGX directly replace PHA6UOA without circuit modification?

A: Yes. The PBH6UOANAGX maintains identical electrical specifications (100mA DC at 30V), circuit configuration (6PDT), switch function (on-momentary), mounting type (through-hole right-angle), and termination style (PC pin). Direct substitution is possible without circuit redesign.

Q: What are the key differences between PBH6UOANAGX and FLT6UOATB?

A: PBH6UOANAGX provides exact electrical equivalence to the original PHA6UOA (100mA DC at 30V). FLT6UOATB offers enhanced current capacity (500mA AC/DC) and voltage rating (125V AC), extended electrical life (100,000 cycles), and dual termination options. Both maintain mechanical compatibility through identical mounting and actuator specifications.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For designs requiring exact parameter matching to the original specification, PBH6UOANAGX is appropriate. For applications benefiting from enhanced performance margins, extended operational life, or flexible termination options, FLT6UOATB is suitable. Both parts are in active production with current compliance certifications.

Q: Are there packaging differences between the substitutes?

A: PBH6UOANAGX is supplied in bulk packaging. FLT6UOATB is also supplied in bulk packaging. Both maintain the same through-hole right-angle mounting footprint as the original PHA6UOA.

Q: Do the substitute parts maintain the same operating temperature range?

A: The original PHA6UOA operates from -10°C to 60°C. PBH6UOANAGX extends this to -20°C to 70°C. FLT6UOATB provides the widest range at -40°C to 70°C. Both substitutes support the original operating range and exceed it, providing additional thermal margin.

Q: What compliance certifications apply to the substitute parts?

A: Both PBH6UOANAGX and FLT6UOATB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original PHA6UOA was RoHS compliant, and both substitutes maintain or exceed this compliance level.
