EVQ-PBC07K Equivalent & Substitute Parts

Part Overview

The EVQ-PBC07K is a tactile switch manufactured by Panasonic Electronic Components, configured as a SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch. This component features top actuation, through-hole mounting, and is rated for 0.02A at 15VDC. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support, legacy system maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVQ-PBC07K is determined by the following critical parameters:

Electrical Compatibility: The substitute part must support SPST-NO circuit configuration with momentary (Off-Mom) switch function. The contact rating must equal or exceed the original specification (0.02A @ 15VDC). The TE Connectivity 1825955-9 provides 0.05A @ 24VDC, which exceeds the original electrical requirements and is therefore electrically compatible.

Mechanical Compatibility: The substitute must maintain identical mounting type (through hole), actuator orientation (top actuated), and outline dimensions (6.00mm x 6.00mm) to ensure PCB footprint compatibility without redesign. Both parts share these mechanical characteristics.

Operational Parameters: Operating force (100gf) and mechanical life (100,000 cycles) must match or exceed the original specification. The substitute part meets these requirements identically.

Environmental and Compliance: The substitute part must maintain RoHS compliance status and support the operating temperature range of the application. The TE Connectivity part provides extended temperature range (-35°C ~ 85°C) and ROHS3 compliance, exceeding the original specifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1825955-9 is a direct functional substitute for the obsolete EVQ-PBC07K based on electrical, mechanical, and compliance parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part exceeds the original electrical specification (0.05A @ 24VDC versus 0.02A @ 15VDC), providing design margin for applications operating within the original voltage and current envelope. The extended operating temperature range (-35°C ~ 85°C versus -20°C ~ 70°C) supports deployment in broader environmental conditions.

The reduced switch travel distance (0.10mm versus 0.25mm) on the substitute part represents a minor operational difference that does not affect circuit functionality in momentary switch applications. This characteristic may result in slightly faster actuation response.

Both parts maintain identical mechanical footprint, outline dimensions, and mounting configuration, enabling direct PCB layout compatibility without redesign. ROHS3 compliance of the substitute part satisfies current regulatory requirements and represents an improvement over the original RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1825955-9 be used as a direct replacement for the EVQ-PBC07K without PCB modification?

A: Yes. Both parts share identical outline dimensions (6.00mm x 6.00mm), actuator height (7.00mm), mounting type (through hole), and termination style (PC pin). Direct PCB footprint compatibility is confirmed.

Q: What is the significance of the different switch travel distances (0.25mm versus 0.10mm)?

A: Switch travel distance represents the distance the actuator moves before electrical contact is established. The reduced travel on the substitute part (0.10mm) results in faster actuation response without affecting the electrical function of the momentary switch circuit. Both distances are within standard tactile switch specifications.

Q: Why does the substitute part have a higher contact rating (0.05A @ 24VDC) than the original (0.02A @ 15VDC)?

A: The higher contact rating provides design margin and allows the substitute part to operate safely in applications with higher voltage or current demands. Applications using the original part at 0.02A @ 15VDC will operate well within the substitute part's electrical envelope, ensuring reliable performance.

Q: Is the extended operating temperature range of the substitute part (-35°C ~ 85°C) a concern for applications designed for -20°C ~ 70°C?

A: No. The extended temperature range of the substitute part is a performance enhancement. Applications designed for the original temperature range will operate within the substitute part's specifications, with additional margin for extreme environmental conditions.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current revision of the Restriction of Hazardous Substances directive, incorporating updated substance restrictions and compliance requirements. Both the original and substitute parts are RoHS compliant; the substitute part meets the more recent ROHS3 standard, ensuring alignment with current regulatory frameworks.

Q: Are there any electrical circuit considerations when substituting this part?

A: No additional circuit modifications are required. The substitute part maintains identical SPST-NO circuit configuration and momentary switch function. The higher contact rating of the substitute part does not require circuit redesign for applications operating within the original electrical specifications.
