Engineering Selection Recommendations

The main part 0366330036 is obsolete. Both substitutes, Molex 0874270842 and Molex 0874270832, are active and match or exceed required compliance, including RoHS3 and MSL 1 (Unlimited). All listed substitutes have matching application fields and material flammability ratings of UL94 V-0. The selection of substitutes is justified by identical electrical and mechanical parameters and series compatibility within the Mini-Fit Jr 87427 family.

Frequently Asked Questions (FAQ)

Q: What are the primary electrical and mechanical parameters considered for substitution?
A: Parameters include connector type (header), mounting type (through hole), number of positions (8), pitch (0.165" / 4.20mm), row count, row spacing, contact material and finish, insulation material, mechanical style, shrouding, fastening type, operating temperature range, material flammability rating, and compliance/certifications.

Q: Are substitute parts 0874270842 and 0874270832 electrically and mechanically identical to 0366330036?
A: Yes, provided key substitution criteria—number of positions, pitch, row spacing, contact and insulation materials, mounting style, and series—are matched.

Q: Are there any differences in compliance or certifications among the listed substitutes?
A: All substitutes listed are RoHS3 compliant and have MSL 1 (Unlimited). Material flammability rating is UL94 V-0 across all matched parts.
