Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810KMCQ is determined by strict alignment across the following critical parameters:

• Circuit topology: SPDT configuration required
• Switch actuation: On-Momentary function required
• Current capacity: Minimum 6A at 125V AC
• Voltage ratings: Minimum 125V AC; DC rating of 28V or higher acceptable
• Mechanical interface: Panel mount, rear configuration with 6.35mm circular cutout
• Actuator design: Plunger-type actuator compatible with standard caps
• Electrical termination: PC pin connection required
• Operating environment: Temperature range of -20°C to 85°C or broader
• Compliance: ROHS3 compliance or equivalent regulatory status

The TE Connectivity ALCOSWITCH 3-1437567-0 meets these substitution criteria with minor parameter variations within acceptable engineering tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 3-1437567-0 is functionally equivalent to the obsolete APEM 810KMCQ for applications requiring SPDT pushbutton switching at 6A 125V AC with on-momentary actuation and panel-mount rear configuration.

Substitution is appropriate when:

• AC load current does not exceed 6A at 125V
• DC load current does not exceed 4A (versus original 7A rating)
• DC voltage does not exceed 28V (versus original 30V rating)
• Operating temperature remains within -20°C to 80°C range
• Electrical cycle life requirement does not exceed 50,000 cycles (versus original 60,000 cycles)
• Panel cutout diameter of 6.35mm circular is available
• PC pin termination is compatible with existing PCB or wiring harness

Substitution requires evaluation when:

• DC current requirements exceed 4A
• DC voltage requirements exceed 28V
• Operating temperature extends below -20°C or above 80°C
• Electrical life requirement exceeds 50,000 cycles
• RoHS3 compliance is a mandatory system requirement

The substitute part is in active production status, ensuring continued availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-1437567-0 directly replace the APEM 810KMCQ in all applications?

A: Direct replacement is possible for most standard AC switching applications at 6A 125V. However, applications with DC loads exceeding 4A, DC voltages above 28V, extreme temperature operation below -20°C or above 80°C, or cycle life requirements above 50,000 cycles require engineering evaluation of the specific application parameters.

Q: What is the primary reason for seeking a substitute for the 810KMCQ?

A: The APEM 810KMCQ is obsolete and no longer in production. The TE Connectivity 3-1437567-0 provides functional equivalence with active production status, ensuring long-term supply availability.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both parts require a 6.35mm diameter circular panel cutout, ensuring mechanical compatibility with existing panel designs.

Q: What are the key electrical differences between these switches?

A: The substitute part has lower DC current rating (4A versus 7A), lower DC voltage rating (28V versus 30V), narrower operating temperature range (-20°C to 80°C versus -30°C to 85°C), and lower electrical life rating (50,000 versus 60,000 cycles). AC ratings remain identical at 6A 125V.

Q: Is the termination style compatible with existing wiring?

A: Both parts use PC pin termination, ensuring compatibility with standard PCB-mounted or harness-connected applications designed for this termination type.

Q: What compliance certifications apply to the substitute part?

A: The TE Connectivity 3-1437567-0 carries EAR99 export classification and HTSUS code 8536.50.9035, identical to the main part. RoHS compliance status for the substitute is listed as not applicable by the manufacturer.
