Substitute Part Grouping Explanation

Substitute parts for the 1445094-5 are grouped into two categories based on substitution compatibility:

Direct Manufacturer Substitute (TE Connectivity): The part 2-1445094-5 is a direct substitute from the same manufacturer, sharing identical electrical and mechanical specifications with the main part. The primary distinction is product status (active versus obsolete) and packaging format (tray). This substitute maintains the same series designation (Micro MATE-N-LOK), contact configuration, pitch, termination method, and operating parameters. The contact finish on the post differs only in composition (tin versus tin-lead), representing a material refinement rather than a functional change.

Cross-Manufacturer Substitutes (Molex): Parts 0436500515, 0436500516, 0436500517, 0436500518, 0436500527, and 0436500529 are Molex Micro-Fit 3.0 43650 series connectors that provide functional equivalence through matching core parameters: 5-position, 3.00mm pitch, through-hole mounting, solder termination, shrouded 4-wall construction, square contact shape, and brass contact material. These substitutes maintain compatibility with the original application interface while offering active product status and enhanced compliance certifications. Variations among Molex substitutes relate to contact finish specifications (tin or gold plating) and fastening features (board lock or board guide), which do not affect fundamental connector function for standard applications.

Key Parameters Determining Substitution: Pitch (3.00mm), number of positions (5), mounting type (through-hole), termination method (solder), shrouding configuration (4-wall), contact shape (square), and contact material (brass).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (TE Connectivity 2-1445094-5): The 2-1445094-5 is the primary recommended substitute for the obsolete 1445094-5. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from tin-lead to tin contact finish on the post represents a material improvement aligned with modern manufacturing standards. This substitute is suitable for direct replacement in all applications where the original part was specified.

Cross-Manufacturer Substitution (Molex Micro-Fit 3.0 Series): The Molex 0436500515, 0436500516, 0436500517, 0436500518, 0436500527, and 0436500529 connectors provide functional equivalence through matching core connector parameters. All Molex substitutes are active products with ROHS3 compliance and REACH unaffected status. Selection among Molex alternatives depends on specific contact finish requirements and fastening feature preferences:

• 0436500515 and 0436500527: Tin mating contact finish; 0436500527 includes solder-only termination
• 0436500516 and 0436500529: Gold mating contact finish; 0436500529 includes solder-only termination
• 0436500517: Gold mating contact finish with enhanced plating thickness (30.0µin)
• 0436500518: Tin mating contact finish with board lock feature

All Molex substitutes feature liquid crystal polymer insulation material with glass filling, providing enhanced mechanical and thermal properties compared to the polyamide nylon insulation of the original part. Insulation height is slightly increased (0.390" versus 0.364"), which may require board layout verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 2-1445094-5 be used as a direct replacement for the 1445094-5?

A: Yes. The 2-1445094-5 is a direct substitute with identical connector specifications, pitch, position count, mounting type, and termination method. The primary differences are product status (active versus obsolete) and packaging format (tray). The contact finish material change from tin-lead to tin represents a compliance improvement without functional impact.

Q: What are the key differences between TE Connectivity and Molex substitutes?

A: The TE Connectivity 2-1445094-5 maintains the original Micro MATE-N-LOK series designation and polyamide nylon insulation. Molex substitutes use the Micro-Fit 3.0 43650 series with liquid crystal polymer insulation and slightly increased insulation height (0.390" versus 0.364"). Both maintain the critical parameters: 3.00mm pitch, 5 positions, through-hole mounting, solder termination, and shrouded 4-wall construction.

Q: Are there compatibility concerns with the increased insulation height of Molex substitutes?

A: The Molex substitutes have an insulation height of 0.390" compared to 0.364" for the original part. This 0.026" (0.66mm) increase should be evaluated against board layout and mating connector clearances. Applications with tight vertical spacing may require design verification.

Q: Which Molex substitute should be selected for gold-plated mating contacts?

A: Three Molex options provide gold mating contact finish: 0436500516, 0436500517, and 0436500529. The 0436500517 offers the thickest gold plating (30.0µin), matching the original part specification. The 0436500529 combines gold mating contacts with solder-only termination.

Q: What is the difference between board lock and board guide features?

A: Board lock (0436500518) and board guide (0436500515, 0436500516, 0436500517, 0436500527, 0436500529) are fastening features that affect connector retention on the PCB. Both provide mechanical stability; selection depends on application requirements and PCB design specifications.

Q: Are all substitute parts RoHS compliant?

A: The original 1445094-5 is RoHS non-compliant. The 2-1445094-5 and all Molex substitutes (0436500515, 0436500516, 0436500517, 0436500518, 0436500527, 0436500529) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: What is the inventory availability of substitute parts?

A: The 2-1445094-5 has 1,430 pieces in stock. Molex substitutes have varying availability: 0436500527 (28,252 pcs), 0436500515 (75,823 pcs), 0436500516 (26,769 pcs), 0436500518 (4,050 pcs), 0436500529 (4,447 pcs), and 0436500517 (4,047 pcs).

Q: Can the tin-lead finish of the original part be replaced with tin finish?

A: Yes. The transition from tin-lead to tin contact finish on the post is a standard material substitution that does not affect electrical or mechanical function. All substitute parts use tin post finish, which is compliant with modern manufacturing standards and RoHS regulations.
