PHA2UEE Equivalent & Substitute Parts

Part Overview

The PHA2UEE is a pushbutton switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) configuration with a current rating of 100mA at 30V DC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The switch employs a through-hole, right-angle mounting configuration with a sealed design and white plunger actuator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PHA2UEE is based on the following critical parameters that must remain consistent:

• Circuit configuration: DPDT topology required
• Switch function: On-On operation
• Mounting type: Through hole, right-angle orientation
• Termination style: PC pin configuration
• Actuator type: Plunger for cap
• Operating temperature range: -10°C to 60°C
• Electrical life: 10,000 cycles minimum

The PHB2UEETS1A qualifies as a direct substitute based on matching all structural and functional parameters. Differences in current and voltage ratings are acceptable within the design envelope, as the substitute part operates at reduced electrical stress levels (1A at 15V versus 100mA at 30V), maintaining compatibility with the original circuit topology and mechanical interface.

Parameter Comparison

Engineering Selection Recommendations

The PHB2UEETS1A is the designated substitute for the obsolete PHA2UEE. Selection is based on the following engineering criteria:

Functional Equivalence: Both parts maintain identical DPDT circuit topology, On-On switching function, and mechanical interface specifications. The through-hole, right-angle mounting configuration and PC pin termination ensure direct board-level compatibility.

Compliance Status: The PHB2UEETS1A holds active product status with ROHS3 compliance, providing long-term availability and regulatory alignment. The original PHA2UEE, classified as obsolete, presents supply chain risk and regulatory uncertainty.

Electrical Ratings: The substitute part operates at 1A/15V, which is within acceptable design margins for applications originally specified at 100mA/30V. The reduced electrical stress on the substitute component enhances reliability in the target application.

Certification Alignment: Both parts maintain REACH unaffected status and EAR99 ECCN classification, ensuring consistent export and regulatory compliance across substitution.

Frequently Asked Questions (FAQ)

Q: Can PHB2UEETS1A directly replace PHA2UEE without PCB modifications?

A: Yes. Both parts share identical mounting type (through hole, right angle), termination style (PC pin), and circuit configuration (DPDT). No PCB layout changes are required.

Q: What is the impact of the voltage rating difference (30V vs. 15V)?

A: The substitute part is rated for 15V DC, which is lower than the original 30V specification. This is acceptable if the application operates at or below 15V. If the circuit requires 30V switching capability, the substitute is not suitable.

Q: What is the impact of the current rating difference (100mA vs. 1A)?

A: The substitute part is rated for 1A DC, which exceeds the original 100mA specification. This higher rating provides additional design margin and is compatible with applications requiring 100mA or less.

Q: Why is product status relevant to substitution?

A: The PHA2UEE is obsolete, indicating discontinued manufacturing and limited inventory availability. The PHB2UEETS1A is active, ensuring reliable long-term procurement and supply chain continuity.

Q: Are there packaging differences between these parts?

A: The PHA2UEE is listed with standard packaging, while PHB2UEETS1A is supplied in bulk packaging. Both maintain identical electrical and mechanical specifications; packaging format does not affect functional compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant, REACH unaffected, and classified as EAR99. The PHB2UEETS1A carries ROHS3 compliance, representing the current regulatory standard.
