Parameter Comparison

Engineering Selection Recommendations

The Molex 0919991249 is the recommended substitute for the obsolete 0908581249 based on the following factors:

Product Status: The 0919991249 maintains active manufacturing status, ensuring long-term availability and supply chain continuity. The original part's obsolete classification makes the substitute necessary for production support.

Compliance: Both parts meet RoHS requirements. The substitute carries RoHS Compliant status while the original is ROHS3 Compliant. Both parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage and handling.

Electrical and Mechanical Compatibility: The substitute part preserves all critical interface parameters: 3-position configuration, 5.00mm pitch, through-hole solder termination, and latch lock fastening. Contact material, finish, and thickness remain identical.

Material Difference: The substitute uses Polyamide (PA66) nylon insulation instead of the original's glass-filled PBT. This material change does not affect mechanical compatibility or electrical performance for standard blade type power connector applications.

Additional Specifications: The substitute provides documented electrical ratings (250 V, 16 A) and operating temperature range (-20°C ~ 120°C) not specified for the original part. The board guide feature in the substitute enhances mechanical stability during assembly.

Frequently Asked Questions (FAQ)

Q: Can the 0919991249 be used as a direct replacement for the 0908581249?

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, and termination approach. The electrical and mechanical interfaces are fully compatible.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The 0908581249 is obsolete, while the 0919991249 is active. Additionally, the insulation material differs: the original uses glass-filled PBT, while the substitute uses PA66 nylon. The substitute also includes a board guide feature and documented electrical ratings.

Q: Are there any compatibility concerns with the insulation material change?

A: No. Both materials are suitable for blade type power connector applications. The PA66 nylon insulation in the substitute meets the same functional requirements as the glass-filled PBT in the original part.

Q: What packaging is available for the substitute part?

A: The 0919991249 is supplied in tube packaging.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, meaning they have no moisture sensitivity constraints and require no special storage or handling procedures.

Q: Are the electrical ratings the same?

A: The substitute part specifies 250 V voltage rating and 16 A current rating. The original part does not have documented electrical ratings in the provided specifications. The substitute's ratings apply to the 0919991249 for applications requiring these specifications.

Q: What is the inventory status for these parts?

A: The original 0908581249 has 738 pieces in stock. The substitute 0919991249 has 918 pieces in stock.
