EVQ-PSG02K Equivalent & Substitute Parts

Part Overview

The EVQ-PSG02K is a tactile switch manufactured by Panasonic Electronic Components, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 12VDC. This component is designed for surface mount, right-angle applications with side actuation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-PSG02K is determined by strict alignment with the following critical parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 12VDC
• Switch function: Off-Mom (Momentary)
• Mounting type: Surface Mount, Right Angle
• Actuator orientation: Side Actuated
• Operating force: 220gf
• Operating temperature range: -20°C ~ 70°C
• Moisture sensitivity level: MSL 1 (Unlimited)

The substitute part 1571262-2 (TE Connectivity ALCOSWITCH Switches) meets all critical electrical and mechanical parameters required for functional equivalence. Both parts share identical circuit configuration, contact rating, switch function, mounting orientation, operating force, temperature range, and moisture sensitivity classification. Dimensional and termination differences (5.40mm x 5.60mm outline with Gull Wing termination versus 4.60mm x 6.10mm with J Lead) are acceptable within the scope of surface mount, right-angle tactile switch applications where PCB layout accommodation is feasible.

Parameter Comparison

Engineering Selection Recommendations

The 1571262-2 is a qualified substitute for the obsolete EVQ-PSG02K based on electrical and mechanical parameter alignment. The substitute part is currently in active production status with 6229 units available in inventory, ensuring supply chain continuity.

The primary design consideration is PCB layout accommodation. The 1571262-2 has a larger outline (5.40mm x 5.60mm) compared to the EVQ-PSG02K (4.60mm x 6.10mm) and uses Gull Wing termination instead of J Lead. These differences require PCB footprint verification and reflow soldering process validation.

The 1571262-2 has a lower mechanical life rating (50,000 cycles versus 100,000 cycles). Applications requiring extended cycle life should evaluate this parameter against actual operational requirements.

Both parts share identical electrical specifications, temperature operating range, and moisture sensitivity classification, supporting direct functional substitution in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 1571262-2 be used as a direct replacement for the EVQ-PSG02K without PCB modification?

A: Electrical substitution is direct. However, PCB footprint modification is required due to dimensional differences (outline and termination style). The 1571262-2 requires a Gull Wing footprint versus the J Lead footprint of the EVQ-PSG02K.

Q: Are there electrical performance differences between these parts?

A: No. Both parts have identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), switch function (Off-Mom), operating force (220gf), and operating temperature range (-20°C ~ 70°C).

Q: What is the significance of the mechanical life difference?

A: The EVQ-PSG02K is rated for 100,000 cycles while the 1571262-2 is rated for 50,000 cycles. Applications with high actuation frequency should evaluate whether the lower cycle rating of the substitute part meets operational requirements.

Q: Is the 1571262-2 RoHS compliant?

A: Yes, the 1571262-2 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging format is available for the 1571262-2?

A: The 1571262-2 is available in Cut Tape (CT) packaging format.
