Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-PJB04K is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• Outline dimensions: 6.00mm x 4.60mm
• Switch travel: 0.25mm

Secondary Compatibility Considerations:

• Contact rating voltage compatibility (12VDC nominal)
• Contact rating current: 0.05A
• Actuator height tolerance
• Operating force range
• Mechanical life cycles
• Operating temperature range

Substitute parts are grouped into two categories:

Direct Substitutes maintain all primary compatibility criteria and electrical specifications identical to the main part.

Similar Substitutes maintain primary compatibility criteria and core electrical function but may vary in secondary parameters such as operating force, actuator height, mechanical life, or operating temperature range. These parts are electrically and mechanically compatible within the specified tolerance parameters but require design review for applications with strict performance requirements.

Parameter Comparison

Engineering Selection Recommendations

EVQ-PE504K is the primary recommended substitute. This Panasonic part maintains identical electrical specifications (0.05A @ 12VDC), mechanical parameters (160gf operating force, 50,000 cycle life), and physical dimensions to the EVQ-PJB04K. The EVQ-PE504K is currently in active production status with 11,121 units in stock. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

FSMH (TE Connectivity ALCOSWITCH Switches) is suitable for applications where higher mechanical life (100,000 cycles) and extended low-temperature operation (-35°C) are beneficial. However, this part operates at 24VDC contact rating and features a 5.00mm actuator height compared to the 4.30mm of the main part. The 130gf operating force is lower than the EVQ-PJB04K specification. This part is ROHS3 compliant and REACH unaffected.

TL1107AF130WQ (E-Switch) maintains the 12VDC contact rating and 4.30mm actuator height of the main part. However, the operating temperature range is limited to -20°C ~ 70°C, and mechanical life is specified at 40,000 cycles. This part is ROHS3 compliant and REACH unaffected.

TL1107BF260WQ (E-Switch) features a higher operating force (260gf) and 5.00mm actuator height. The operating temperature range is limited to -20°C ~ 70°C, and mechanical life is specified at 30,000 cycles. This part is ROHS3 compliant and REACH unaffected.

All substitute parts maintain SPST-NO circuit configuration, through-hole mounting, top actuation, and 0.25mm switch travel. Selection should be based on specific application requirements regarding operating force, temperature range, mechanical life, and physical clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can EVQ-PE504K be used as a direct replacement for EVQ-PJB04K?

A: Yes. The EVQ-PE504K maintains identical electrical specifications (0.05A @ 12VDC), mechanical parameters (160gf operating force, 50,000 cycle life), and physical dimensions (6.00mm x 4.60mm outline, 4.30mm actuator height). Both parts feature SPST-NO configuration, through-hole mounting, and 0.25mm switch travel. The primary difference is product status: EVQ-PE504K is active production while EVQ-PJB04K is obsolete.

Q: What are the key differences between the Panasonic EVQ-PE504K and TE Connectivity FSMH?

A: The EVQ-PE504K operates at 12VDC with 160gf operating force and 50,000 cycle mechanical life. The FSMH operates at 24VDC with 130gf operating force and 100,000 cycle mechanical life. The FSMH features a 5.00mm actuator height compared to 4.30mm for the EVQ-PE504K. Both maintain identical outline dimensions (6.00mm x 4.60mm) and 0.25mm switch travel. The FSMH is suitable for applications requiring higher mechanical durability and extended low-temperature operation (-35°C).

Q: Are the E-Switch TL1107 series parts compatible with the EVQ-PJB04K?

A: The TL1107AF130WQ and TL1107BF260WQ maintain SPST-NO configuration, through-hole mounting, top actuation, and 0.25mm switch travel. Both operate at 12VDC contact rating. However, both E-Switch parts have operating temperature ranges limited to -20°C ~ 70°C compared to the EVQ-PJB04K specification of -30°C ~ 85°C. The TL1107AF130WQ provides 40,000 cycle mechanical life, while the TL1107BF260WQ provides 30,000 cycles. Operating force differs: TL1107AF130WQ is 130gf and TL1107BF260WQ is 260gf. These parts are suitable for applications within the restricted temperature range.

Q: What packaging formats are available for substitute parts?

A: EVQ-PE504K, FSMH, TL1107AF130WQ, and TL1107BF260WQ are all available in bulk packaging. Specific packaging quantities and tape-and-reel options should be confirmed with the component supplier based on production volume requirements.

Q: Do all substitute parts meet current regulatory compliance standards?

A: EVQ-PE504K, FSMH, TL1107AF130WQ, and TL1107BF260WQ are all ROHS3 compliant and REACH unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.50.9031. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: Which substitute part should be selected for applications requiring the widest operating temperature range?

A: The FSMH provides the widest operating temperature range at -35°C ~ 85°C compared to the EVQ-PJB04K specification of -30°C ~ 85°C. However, the FSMH operates at 24VDC and features different mechanical parameters. For applications requiring the EVQ-PJB04K temperature range with 12VDC operation, the EVQ-PE504K is the appropriate selection.
