Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1825042-7 is determined by strict equivalence across the following critical parameters: DPDT circuit configuration, On-Momentary switch function, 6A AC current rating, 125V AC voltage rating, panel mount rear configuration, round button actuator, and solder lug termination. All substitute parts must maintain these electrical and mechanical specifications to ensure functional compatibility within existing applications.

The substitute parts identified fall into two categories based on manufacturer and product status:

Direct Equivalent (Active Status): MPG206R from TE Connectivity ALCOSWITCH Switches maintains identical electrical ratings, mechanical configuration, and termination style while offering active product status and improved availability.

Similar Equivalents (Obsolete Status): MB2061SB1W01-BA and MB2061SB1W01-CA from NKK Switches provide functional equivalence with minor parameter variations that remain within acceptable substitution tolerances for most applications. These parts share the same circuit configuration, AC current and voltage ratings, mounting type, and termination style.

Parameter Comparison

Engineering Selection Recommendations

MPG206R is the primary recommended substitute for the TE Connectivity 1825042-7. This part maintains identical electrical specifications, mechanical configuration, and operating parameters while offering active product status. MPG206R provides superior long-term availability and supply chain stability. The part is ROHS3 compliant, supporting modern regulatory requirements. Inventory availability of 20,100 units ensures procurement reliability for both immediate replacement and future production requirements.

MB2061SB1W01-BA and MB2061SB1W01-CA from NKK Switches serve as secondary substitutes for applications where DC current requirements do not exceed 3A and panel cutout diameter can accommodate 12.50mm openings. Both parts maintain the required 6A AC and 125V AC ratings essential for AC-dominant applications. The NKK switches feature epoxy sealed terminals and extended mechanical life ratings of 100,000 cycles, providing enhanced durability in certain operating environments. However, both parts carry obsolete product status, limiting their suitability for new designs requiring long-term component availability.

Selection between MB2061SB1W01-BA and MB2061SB1W01-CA should be based on specific connector pin configuration requirements, as these variants differ in their termination pin arrangements.

Frequently Asked Questions (FAQ)

Q: Can MPG206R directly replace the TE Connectivity 1825042-7 in existing applications?

A: Yes. MPG206R maintains identical electrical ratings (6A AC, 4A DC, 125V AC, 28V DC), circuit configuration (DPDT), switch function (On-Momentary), mounting type (panel mount rear), actuator type (round button), termination style (solder lug), and panel cutout diameter (11.80mm). Direct substitution is functionally equivalent.

Q: What are the key differences between the NKK Switches alternatives and the original part?

A: MB2061SB1W01-BA and MB2061SB1W01-CA differ in three parameters: DC current rating (3A versus 4A), panel cutout diameter (12.50mm versus 11.80mm), and electrical life (25,000 cycles versus 50,000 cycles). DC voltage rating is slightly higher at 30V versus 28V. These parts feature epoxy sealed terminals and extended mechanical life of 100,000 cycles.

Q: Are there panel cutout compatibility concerns when substituting with NKK Switches parts?

A: Yes. The NKK Switches alternatives require a 12.50mm diameter panel cutout compared to the 11.80mm requirement of the original part. Panel modifications may be necessary for mechanical installation. The TE Connectivity MPG206R maintains the original 11.80mm cutout diameter, eliminating this compatibility concern.

Q: Which substitute part offers the best long-term availability?

A: MPG206R provides the highest inventory availability at 20,100 units and maintains active product status. This ensures reliable procurement for both immediate replacement needs and sustained production requirements. The NKK Switches alternatives carry obsolete status, limiting their suitability for applications requiring extended component availability.

Q: Are all substitute parts RoHS and REACH compliant?

A: MPG206R is ROHS3 compliant and REACH affected. MB2061SB1W01-BA and MB2061SB1W01-CA are ROHS3 compliant and REACH unaffected. The original 1825042-7 is REACH unaffected with unspecified RoHS status. Regulatory compliance requirements should be verified against specific application standards.

Q: What is the impact of reduced DC current rating in the NKK Switches alternatives?

A: The NKK Switches parts are rated for 3A DC versus 4A DC on the original part. Applications operating at DC currents exceeding 3A require the TE Connectivity MPG206R or original 1825042-7. AC applications are unaffected, as all parts maintain the 6A AC rating.

Q: Can the electrical life difference affect component selection?

A: The original 1825042-7 and MPG206R are rated for 50,000 electrical cycles, while NKK Switches alternatives are rated for 25,000 cycles. Applications requiring extended cycle life should prioritize TE Connectivity parts. The NKK alternatives offer superior mechanical life at 100,000 cycles, which may offset electrical life considerations in specific mechanical stress environments.
