Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZ-2RN730 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 15A (AC) and 500mA (DC)
• Voltage rating: 125V (AC and DC)

Mechanical Parameters:

• Actuator type: Overtravel Plunger
• Mounting type: Panel Mount
• Termination style: Screw Terminal
• Operating force: 255–368 gf
• Release force: 113 gf
• Operating position: 1.720" (43.7 mm)
• Pretravel: 0.015" (0.4 mm)
• Differential travel: 0.002" (0.05 mm)
• Overtravel: 0.219" (5.6 mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 85°C
• Mechanical life: 20,000,000 cycles
• RoHS compliance status
• Moisture sensitivity level: 1

The substitute part BZ-2RQ77 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BZ-2RQ77 is a direct functional and mechanical equivalent to the BZ-2RN730. Both components share identical electrical ratings, mechanical specifications, and environmental operating parameters. The primary distinction is product status: the BZ-2RN730 is obsolete, while the BZ-2RQ77 maintains active status.

For new designs or ongoing production requiring SPDT snap action switches with 15A AC / 500mA DC capacity at 125V with panel mount configuration and screw terminal termination, the BZ-2RQ77 is the appropriate selection. Both parts carry RoHS compliance certification and identical moisture sensitivity classification, ensuring regulatory and environmental compatibility.

The BZ-2RQ77 is available in bulk packaging with confirmed inventory of 1,238 pieces in stock, supporting both prototype and production-volume requirements.
