Substitute Part Grouping Explanation

Substitution eligibility for the MA250DMFMK is determined by the following critical parameters:

• Connector Configuration: Convert from 0.25" (6.35mm) 1/4" Quick Connect male (2) to 0.25" (6.35mm) 1/4" Quick Connect female
• Contact Material: Brass composition
• Insulation Type: Non-insulated construction
• Environmental Classification: MSL 1 (Unlimited) moisture sensitivity rating
• Regulatory Compliance: REACH Unaffected status

The MA250DMMFK meets all substitution criteria as an active product with identical electrical and mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can MA250DMMFK be used as a direct replacement for MA250DMFMK? A: Yes. Both parts maintain identical connector configurations (0.25" male to 0.25" female), brass contact material, non-insulated construction, and MSL 1 rating. The substitute is functionally and mechanically equivalent.

Q: What is the primary difference between these parts? A: The MA250DMFMK is obsolete, while MA250DMMFK is an active product. The substitute includes RoHS Compliance certification. Terminal stacking configuration differs (stacked vs. side by side), but this does not affect substitution eligibility for the specified connector interface.

Q: Are there packaging differences? A: The main part has unspecified packaging, while the substitute is supplied in bag packaging. This does not affect electrical or mechanical performance.

Q: Do both parts meet the same regulatory requirements? A: Both parts are REACH Unaffected and classified as EAR99 under export control. The substitute carries additional RoHS Compliance certification.

Q: Is inventory availability a consideration? A: The substitute part has confirmed inventory of 1230 pcs in stock, supporting immediate procurement requirements.
