Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50044C43-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Chassis Mount
• Voltage rating must support minimum 125V AC operation
• Current rating must support minimum 100mA operation
• Actuator type must be lever-based
• Termination style must be Quick Connect format

Secondary Compatibility Considerations:

• Operating temperature range should encompass the application environment
• Electrical and mechanical life ratings should meet or exceed application cycle requirements
• Termination connector size compatibility (0.187" or 0.250" quick connect)

The substitute parts listed below meet the primary compatibility criteria and represent active or available alternatives to the obsolete AM50044C43-A.

Parameter Comparison

Engineering Selection Recommendations

V7-1S17D8-022 (Honeywell) provides the closest electrical match to the AM50044C43-A, with identical 100mA AC current rating at 125V, matching SPDT circuit configuration, and equivalent electrical life of 100,000 cycles. This part uses 0.187" quick connect termination, matching the original connector size. RoHS compliance and active product status ensure long-term availability. Operating temperature range is -40°C to 85°C, which is narrower than the original but suitable for most industrial applications.

V7-1B19D8-022 (Honeywell) offers higher current capacity (11A AC, 500mA DC) while maintaining 125V AC/DC voltage ratings and 100,000 cycle electrical life. This part accommodates applications requiring greater current headroom. The 0.187" quick connect termination matches the original. RoHS compliance and active status support long-term procurement.

V7-3E17E9-022 (Honeywell) provides 10A AC current capacity at 125V with extended DC voltage rating (125V DC). This part uses 0.250" quick connect termination, requiring connector adaptation. Electrical and mechanical life ratings match the original specification. RoHS compliance and active status ensure availability.

MAB104G01C04B01A (APEM Inc.) delivers 16A AC current at 125V with operating temperature range of -10°C to 105°C, closely matching the original temperature specification. This part uses 0.250" quick connect termination. ROHS3 compliance and active status support procurement continuity.

LS085R104F085C1A (E-Switch) operates at reduced voltage (20V AC/DC) and current (0.4VA), limiting application scope to lower-power circuits. This part is suitable only for applications with voltage and current requirements below the original specification. ROHS3 compliance and active status are available.

Frequently Asked Questions (FAQ)

Q: Can V7-1S17D8-022 directly replace AM50044C43-A without modification?

A: V7-1S17D8-022 is electrically compatible with identical current and voltage ratings at 125V AC. Both use 0.187" quick connect termination, allowing direct connector compatibility. The primary difference is operating temperature range (-40°C to 85°C versus -25°C to 105°C). Verify that your application environment falls within the V7-1S17D8-022 temperature range before substitution.

Q: What is the difference between the Honeywell V7 series options?

A: V7-1S17D8-022 matches the original 100mA current rating exactly. V7-1B19D8-022 provides 11A AC capacity for higher-power applications. V7-3E17E9-022 offers 10A AC with extended DC voltage support (125V DC). All three maintain 125V AC operation and 100,000 cycle electrical life. Termination connector size differs between models (0.187" for V7-1S17D8-022 and V7-1B19D8-022; 0.250" for V7-3E17E9-022).

Q: Is LS085R104F085C1A suitable for 125V applications?

A: No. LS085R104F085C1A is rated for maximum 20V AC/DC operation, making it unsuitable for 125V circuits. This part is only applicable to low-voltage applications with voltage requirements of 20V or below.

Q: What connector modifications are required for V7-3E17E9-022 or MAB104G01C04B01A?

A: Both parts use 0.250" quick connect termination, while the original AM50044C43-A uses 0.187" termination. Connector adapters or harness modification is required for physical installation. Verify connector compatibility with your application's mating connector before substitution.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All listed substitute parts carry RoHS or ROHS3 compliance certification. The original AM50044C43-A compliance status is not specified in available documentation.

Q: Which substitute part has the longest mechanical life?

A: V7-1S17D8-022, V7-1B19D8-022, and V7-3E17E9-022 all provide 10,000,000 cycle mechanical life, matching the original AM50044C43-A specification. LS085R104F085C1A provides 1,000,000 cycles, and MAB104G01C04B01A mechanical life is not specified.

Q: Can I use MAB104G01C04B01A in applications requiring -25°C operation?

A: MAB104G01C04B01A operates from -10°C to 105°C. Applications requiring operation below -10°C require V7-1B19D8-022 or V7-1S17D8-022 (-40°C minimum), or the original AM50044C43-A specification (-25°C minimum).
