GPTBLS11 Equivalent & Substitute Parts

Part Overview

The GPTBLS11 is a snap action SPDT switch manufactured by ZF Electronics, designed for chassis mount applications with 20A AC at 125V rating. This switch features a straight lever actuator and screw terminal connections, suitable for on-momentary switching functions. The part is currently active in production status with 967 units in stock.

Identifying equivalent and substitute parts becomes necessary when the primary part reaches end-of-life, experiences supply constraints, or when design requirements allow for alternative components meeting compatible electrical and mechanical specifications.

Engineering Selection Recommendations

BM-2RW8424-A2 (Honeywell Sensing and Productivity Solutions)

This part meets all core substitution criteria with a current rating of 22A AC, exceeding the GPTBLS11 requirement of 20A. The voltage rating of 125V AC matches the primary part. Both parts share identical circuit configuration (SPDT), switch function (On-Mom), mounting type (Chassis Mount), termination style (Screw Terminal), and mechanical life (20,000,000 cycles). The BM-2RW8424-A2 provides an extended operating temperature range of -55°C to 121°C compared to the GPTBLS11 range of 0°C to 55°C. However, the part carries an Obsolete product status. RoHS compliance is confirmed for both parts.

SCN-2623SC (Honeywell Sensing and Productivity Solutions)

This part shares the same circuit configuration, switch function, mounting type, termination style, and mechanical life as the GPTBLS11. The voltage rating of 125V AC is identical. However, the current rating of 1A AC is significantly lower than the GPTBLS11 requirement of 20A AC. This part is suitable only for applications with substantially reduced current demands. The part carries an Obsolete product status. RoHS compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can BM-2RW8424-A2 directly replace GPTBLS11 in existing designs?

A: BM-2RW8424-A2 meets the electrical and mechanical substitution criteria for GPTBLS11. Both parts support SPDT configuration, On-Mom function, 125V AC operation, and 20,000,000 mechanical cycles. The higher current rating of 22A AC provides margin above the 20A requirement. Mechanical parameters including operating force, release force, and operating position differ slightly but remain within the same functional class. Verification of mechanical fit in the specific chassis mount application is required.

Q: Is SCN-2623SC suitable as a substitute for GPTBLS11?

A: SCN-2623SC is not suitable for direct substitution in applications requiring 20A AC operation. The current rating of 1A AC is insufficient for the GPTBLS11 design specification. This part is applicable only to circuits with significantly lower current requirements.

Q: What is the impact of product status on part selection?

A: Both substitute parts carry Obsolete product status, indicating discontinued manufacturing. GPTBLS11 maintains Active status with current production availability. Selection of obsolete parts introduces supply risk and should be evaluated against long-term component availability requirements.

Q: How do operating temperature ranges affect substitution decisions?

A: BM-2RW8424-A2 and SCN-2623SC both provide extended operating temperature ranges (-55°C to 121°C) compared to GPTBLS11 (0°C to 55°C). If the application operates within the GPTBLS11 temperature specification, the extended range of substitute parts provides additional thermal margin. If the application requires operation outside the GPTBLS11 range, the substitute parts may offer improved performance.

Q: Are there compliance differences between GPTBLS11 and the substitute parts?

A: GPTBLS11 is ROHS3 Compliant. BM-2RW8424-A2 and SCN-2623SC are RoHS Compliant. Both compliance levels meet regulatory requirements for electronic components. All parts carry EAR99 ECCN classification.
