Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MK15-501-C-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST-NO)
• Switching current rating (500mA AC/DC minimum)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Operate range (15–20AT)
• Type (Molded Body Reed)

Allowable Variation Parameters:

• Switching voltage (must equal or exceed 200V AC/DC)
• Operating temperature range (may extend beyond -40°C to 125°C)
• Release time (may be equal to or faster than 0.1ms)
• Body dimensions (minor variations acceptable within manufacturing tolerance)
• Packaging format (may differ from original)
• Product status (active parts preferred over obsolete)

The MK15-C-2 qualifies as a direct substitute based on matching all mandatory parameters while offering improved availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

MK15-C-2 as Primary Substitute:

The MK15-C-2 is functionally equivalent to the MK15-501-C-2 for applications operating at or below 180V AC/DC. Both parts share identical circuit configuration, switching current, power rating, operate range, and timing characteristics. The MK15-C-2 offers the following advantages:

• Active Product Status: The MK15-C-2 is actively manufactured by Standex-Meder Electronics, ensuring long-term supply availability and manufacturing consistency compared to the obsolete MK15-501-C-2.

• Extended Operating Temperature: The MK15-C-2 supports operation to 130°C, providing a 5°C margin above the MK15-501-C-2 specification.

• Faster Release Time: The MK15-C-2 exhibits 0.05ms release time versus 0.1ms for the main part, enabling faster de-energization response.

• Standard Packaging: The MK15-C-2 is supplied in Tape & Reel format, facilitating automated assembly processes.

Voltage Consideration:

The MK15-501-C-2 is rated for 200V switching voltage, while the MK15-C-2 is rated for 180V. For applications requiring 200V switching capability, the MK15-501-C-2 must be retained. For applications operating at 180V or below, the MK15-C-2 provides direct substitution with improved availability.

Compliance Status:

Both parts carry REACH Unaffected status and EAR99 export classification. The MK15-C-2 includes RoHS3 compliance certification, meeting current regulatory requirements for electronic components.

Frequently Asked Questions (FAQ)

Q: Can the MK15-C-2 replace the MK15-501-C-2 in all applications?

A: The MK15-C-2 is functionally equivalent for applications operating at 180V AC/DC or below. Applications requiring 200V switching voltage must use the MK15-501-C-2 or identify alternative parts rated for 200V operation.

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

A: The switching voltage rating differs: MK15-501-C-2 is rated for 200V, while MK15-C-2 is rated for 180V. All other electrical and mechanical parameters are identical or superior in the MK15-C-2.

Q: Why is the MK15-501-C-2 obsolete?

A: The MK15-501-C-2 has been discontinued by Standex-Meder Electronics. The MK15-C-2 represents the active product line continuation with equivalent functionality.

Q: Does packaging format affect electrical performance?

A: No. The MK15-C-2 supplied in Tape & Reel format is electrically identical to the MK15-501-C-2. Packaging format affects only handling, storage, and assembly processes.

Q: Are there any thermal performance differences?

A: The MK15-C-2 supports operation to 130°C versus 125°C for the MK15-501-C-2. Both parts maintain identical electrical ratings across their respective operating temperature ranges.

Q: What does the faster release time of the MK15-C-2 mean for circuit design?

A: The MK15-C-2 releases (de-energizes) in 0.05ms compared to 0.1ms for the MK15-501-C-2. This faster response may benefit applications requiring rapid switch disengagement, but does not affect compatibility for standard switching applications.

Q: Are both parts RoHS compliant?

A: The MK15-C-2 carries RoHS3 compliance certification. The MK15-501-C-2 compliance status is not specified in available documentation. For applications requiring RoHS certification, the MK15-C-2 is the appropriate selection.
