Scotchlok MA250DMMFK – Frequently Asked Questions

1) Will the Scotchlok MA250DMMFK adapter fit 1/4 inch quick-disconnect terminals?
Yes. The MA250DMMFK mates with 0.25 inch wide male and female tabs, and its own pad width is 0.25 inch, so it works with standard 1/4 inch quick-disconnect terminals already crimped on wire. Overall length is 0.76 inch (19.3 mm) and tab thickness is 0.032 inch, which is the usual QD tab stock.
2) What does a double male-female adapter actually do in a wiring harness?
It joins two terminals that are already crimped onto wires, so you don't have to cut and re-terminate. The MA250DMMFK carries a male tab and a female receptacle on each end (double male-female orientation), letting you link two existing quick-disconnects together as an inline junction or branch point.
3) Is this adapter rated for 600V building wire and 1000V fixture wire?
The maximum recommended voltage rating is 606V, which covers 600V building wire. The product description also calls out 1000V use for signs, fixtures, and luminaires.
4) Can I use this adapter inside a hot luminaire or ballast compartment?
Yes, within 250 degrees C (482 degrees F) maximum operating temperature. That covers fixture and ballast compartments where ordinary nylon-insulated terminals would be out of range. Because the adapter is non-insulated, you need to maintain clearance or sleeve it so exposed metal can't contact the housing or adjacent conductors.
5) Is this adapter UL Listed and CSA certified, and what are the file numbers?
Both. Agency approvals are UL and CSA, under UL file E70512 and CSA file LR22190. It is also RoHS 2011/65/EU compliant without exemption, which matters for submittals on government and institutional jobs.
6) Does the MA250DMMFK come with insulation or do I need to sleeve it myself?
It ships non-insulated with a butted-seam barrel, so all metal is exposed. If the connection sits where it could be touched or could short to a grounded surface, add heat shrink or a nylon sleeve rated for your operating temperature.
7) Do I need a crimp tool for this adapter?
No. The MA250DMMFK is an adapter, not a crimp terminal. It has no wire barrel to crimp; it simply plugs between two 0.25 inch quick-disconnects that are already terminated. Any crimping happens on the terminals themselves, not on this piece.
