Frequently Asked Questions (FAQ)
Q: Can the MDF7-18P-2.54DSA(96) be used as a direct replacement for the MDF7-18P-2.54DSA(01)?
A: Yes. Both parts are identical in electrical and mechanical specifications. The primary difference is product status: the (01) variant is obsolete while the (96) variant is active. The (96) variant is the current production equivalent.
Q: What are the key parameters that define substitution compatibility?
A: Substitution compatibility is determined by: 18-position count, 0.100" (2.54mm) pitch spacing, male pin contact type, through-hole mounting, solder termination, 3A current rating, 250V voltage rating, and -35°C ~ 85°C operating temperature range.
Q: Does the packaging difference affect compatibility?
A: No. The packaging difference (bulk vs. bag) does not affect functional or mechanical compatibility. Packaging is a logistics consideration only.
Q: Are both parts RoHS compliant?
A: Yes. Both the MDF7-18P-2.54DSA(01) and MDF7-18P-2.54DSA(96) are RoHS compliant and carry UL94 V-0 flammability certification.
Q: What is the moisture sensitivity level for these connectors?
A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity and no special storage or handling requirements.
