Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2028SS4G03 is determined by the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.50mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Bushing thread specification (M6 x 0.75)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (50,000 Cycles)

The substitute part MN28SS4G03 from NKK Switches maintains compatibility with these core parameters, enabling direct functional replacement in applications requiring the M2028SS4G03.

Parameter Comparison

Engineering Selection Recommendations

The MN28SS4G03 is the designated manufacturer-recommended substitute for the obsolete M2028SS4G03. Both components are manufactured by NKK Switches and maintain identical electrical specifications, circuit configuration, and mechanical mounting parameters. The MN28SS4G03 carries Active product status with current manufacturing support, whereas the M2028SS4G03 is obsolete with no ongoing production. Both parts maintain ROHS3 compliance and equivalent regulatory certifications (ECCN: EAR99, HTSUS: 8536.50.9065).

Selection of the MN28SS4G03 for new designs or replacement applications is supported by its active production status, maintained compliance certifications, and full parameter equivalence to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the MN28SS4G03 directly replace the M2028SS4G03 in existing applications?

A: Yes. The MN28SS4G03 maintains identical electrical ratings (0.4VA at 28V AC/DC), circuit configuration (DPDT), mounting type (Panel Mount), and termination style (PC Pin). Both components share the same panel cutout dimensions and bushing thread specification, enabling direct mechanical and electrical substitution.

Q: What is the primary difference between these two parts?

A: The M2028SS4G03 is obsolete with no current manufacturing availability. The MN28SS4G03 is an active product with ongoing production support from NKK Switches. All functional and electrical parameters remain equivalent.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9065). No compliance differences exist between the two components.

Q: What parameters must remain constant for substitution compatibility?

A: The following parameters must match for direct substitution: circuit configuration (DPDT), switch function (Mom-Off-Mom), current rating (0.4VA), voltage rating (28V AC/DC), mounting type (Panel Mount), actuator type and length, termination style (PC Pin), panel cutout dimensions (Circular - 6.50mm Dia), and bushing thread (M6 x 0.75).

Q: Is the MN28SS4G03 available in the same packaging format?

A: Both parts are supplied in Bulk packaging, maintaining consistency in procurement and inventory management.
