Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RW822-P4 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Current rating must support minimum 15A AC at 125V AC
• Voltage ratings must support 125V AC operation
• DC current capability should align with 500mA minimum

Mechanical Compatibility Requirements:

• Actuator type must be Lever with Roller
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Operating position, differential travel, and overtravel must be within acceptable mechanical envelope tolerances

Compliance Requirements:

• RoHS compliance status must be documented
• Moisture sensitivity level must be 1 (Unlimited) or equivalent

Based on these criteria, the substitute parts are grouped as follows:

Group A - Full Electrical Equivalents (15A AC Rating):

• GPTCRM01 (ZF Electronics)
• GPTCRM11 (ZF Electronics)

Group B - Reduced Current Rating (1A AC Rating):

• TZ-1GV22 (Omron Automation and Safety)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

GPTCRM01 and GPTCRM11 from ZF Electronics are the primary substitutes for BZ-2RW822-P4. Both parts maintain electrical equivalence at 15A AC and 125V AC ratings, identical SPDT circuit configuration, and matching mechanical parameters including operating position, differential travel, and overtravel. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The ZF Electronics parts are suitable for applications requiring the full 15A AC current capacity of the original Honeywell component.

For Current-Limited Applications:

TZ-1GV22 from Omron Automation and Safety is a substitute only for applications where the circuit current requirement does not exceed 1A AC. This part maintains SPDT configuration, On-Momentary function, and 125V AC voltage rating. The Omron part offers extended operating temperature range (-65°C to 400°C) compared to the original part, but provides significantly reduced mechanical life (100,000 cycles versus 20,000,000 cycles) and lower DC voltage rating (30V versus 125V). Selection of TZ-1GV22 is restricted to low-current switching applications.

Compliance Considerations:

All substitute parts carry ROHS3 compliance documentation. The original BZ-2RW822-P4 is RoHS Compliant. All candidates maintain MSL 1 (Unlimited) rating, ensuring compatibility with standard storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can GPTCRM01 or GPTCRM11 be used as direct replacements for BZ-2RW822-P4?

A: GPTCRM01 and GPTCRM11 are electrically and mechanically equivalent for applications requiring 15A AC at 125V AC. Both maintain SPDT configuration, On-Momentary function, lever roller actuator, chassis mount configuration, and screw terminal termination. Operating position, differential travel, and overtravel parameters are within acceptable tolerance. Both are active products with current inventory availability.

Q: What is the difference between GPTCRM01 and GPTCRM11?

A: GPTCRM01 and GPTCRM11 are functionally identical. Both are manufactured by ZF Electronics, carry the same electrical ratings (15A AC, 125V AC), mechanical specifications, and compliance certifications. Selection between these parts may be based on packaging preference (both supplied in Bulk) or inventory availability.

Q: When is TZ-1GV22 appropriate as a substitute?

A: TZ-1GV22 is appropriate only for applications where circuit current does not exceed 1A AC. This part is not suitable for circuits requiring the 15A AC capacity of the original BZ-2RW822-P4. Additionally, TZ-1GV22 provides 30V DC rating versus 125V DC on the original part, limiting its use in higher DC voltage applications.

Q: Are there temperature range limitations with the ZF Electronics substitutes?

A: GPTCRM01 and GPTCRM11 operate within 0°C to 55°C range, compared to -55°C to 85°C for the original BZ-2RW822-P4. Applications requiring operation below 0°C or above 55°C cannot use these ZF Electronics substitutes. TZ-1GV22 supports -65°C to 400°C operation.

Q: What are the mechanical life differences?

A: BZ-2RW822-P4, GPTCRM01, and GPTCRM11 all provide 20,000,000 cycle mechanical life. TZ-1GV22 provides 100,000 cycles, representing a 200-fold reduction in mechanical life rating. Applications with high cycle count requirements should not use TZ-1GV22.

Q: Are all substitutes RoHS compliant?

A: Yes. BZ-2RW822-P4 is RoHS Compliant. GPTCRM01, GPTCRM11, and TZ-1GV22 are all ROHS3 Compliant, meeting current regulatory requirements.

Q: What packaging options are available?

A: BZ-2RW822-P4, GPTCRM01, and GPTCRM11 are supplied in Bulk packaging. TZ-1GV22 is supplied in Tray packaging. Packaging selection may affect procurement and handling procedures.
