Substitute Part Grouping Explanation

Substitution of the obsolete 1825042-1 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH MPG series. The substitute part MPG106D maintains identical specifications across all critical parameters that determine functional compatibility:

Electrical Parameters (Must Match):

• Circuit configuration: SPDT
• Current rating: 6A AC / 4A DC
• Voltage rating: 125V AC / 28V DC
• Electrical life: 50,000 cycles

Mechanical Parameters (Must Match):

• Mounting type: Panel Mount, Rear
• Actuator type: Round, Button
• Termination style: Solder Lug
• Panel cutout dimensions: Circular 11.80mm diameter
• Operating temperature range: -20°C to 80°C

The MPG106D is an active product within the same series, providing direct functional replacement with identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MPG106D is the direct equivalent substitute for the obsolete 1825042-1. Selection of MPG106D is based on the following engineering criteria:

Product Status: The MPG106D is an active product, ensuring ongoing availability and manufacturer support. The 1825042-1 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The MPG106D carries ROHS3 compliance certification, meeting current environmental and material restriction standards. This represents an improvement over the original part specification.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. Direct substitution in existing designs requires no circuit modification or mechanical redesign.

Availability: The MPG106D maintains higher inventory levels (2264 units) compared to the original part (784 units), supporting both immediate and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can MPG106D be used as a direct replacement for 1825042-1 in existing applications?

A: Yes. The MPG106D provides direct functional replacement. All electrical ratings (6A at 125V AC, 4A at 28V DC), circuit configuration (SPDT), mechanical mounting (panel mount rear), and termination style (solder lug) are identical. No circuit or mechanical modifications are required.

Q: What is the difference in packaging between these parts?

A: The 1825042-1 is packaged in standard format, while the MPG106D is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging selection depends on procurement volume and inventory management requirements.

Q: Are there any compliance differences between the two parts?

A: The MPG106D includes ROHS3 compliance certification, which the original part does not specify. Both parts are rated for the same operating temperature range (-20°C to 80°C) and electrical life (50,000 cycles). The MPG106D is REACH Affected, while the original is REACH Unaffected; however, this does not impact functional compatibility.

Q: What are the critical parameters for substitution in this product category?

A: For SPDT pushbutton switches, the critical parameters are circuit configuration, current and voltage ratings, mounting type, panel cutout dimensions, and termination style. The MPG106D matches all these parameters with the 1825042-1.

Q: Is the panel cutout dimension identical for both parts?

A: Yes. Both parts require a circular 11.80mm diameter panel cutout. Existing panel designs require no modification for component substitution.

Q: What is the electrical life specification for both parts?

A: Both the 1825042-1 and MPG106D are rated for 50,000 electrical cycles, ensuring equivalent operational durability in switching applications.
