Engineering Selection Recommendations

The original part 75844-150-72 is classified as obsolete. Direct equivalent 75844-150-72LF from Amphenol ICC (FCI) maintains identical mechanical and electrical specifications while achieving RoHS compliance and providing an extended operating temperature range of -65°C to 130°C with 5A current rating.

For active production designs, manufacturer-recommended alternatives from Sullins Connector Solutions and Samtec Inc. provide superior compliance posture. All substitute parts carry active product status and ROHS3 compliance certification. The Sullins PBC36 and PEC36 series offer multiple contact post length options to accommodate varying PCB stack-up requirements, while maintaining consistent mating contact geometry and pitch specifications.

Samtec MTLW-136-08-G-D-273 provides the highest current rating at 5.2A per contact and extended operating temperature range of -55°C to 125°C, with liquid crystal polymer insulation material offering enhanced dimensional stability.

Selection between gold-plated mating contacts (PBC36DAAN, PBC36DABN, PBC36DACN, PBC36DAFN, PBC36DAHN) and tin-plated mating contacts (PEC36DAAN, PEC36DABN) depends on application requirements for contact resistance and corrosion resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can I substitute 75844-150-72 with 75844-150-72LF directly?

A: Yes. The 75844-150-72LF is a direct equivalent from the same manufacturer with identical mechanical and electrical specifications. The primary differences are RoHS compliance and extended operating temperature range (-65°C to 130°C versus unspecified for the original). Both maintain the same 72-position, 2-row configuration at 0.100" pitch with identical contact geometry and solder termination.

Q: What is the key difference between PBC36 and PEC36 series substitutes?

A: The primary difference is contact finish on the mating side. PBC36 series features gold-plated mating contacts (10.0µin thickness), while PEC36 series features tin-plated mating contacts (100.0µin thickness). Both series maintain identical position count, pitch, and mechanical dimensions. Selection depends on application requirements for contact resistance and environmental corrosion exposure.

Q: Do all substitute parts have the same contact post length?

A: No. Sullins PBC36 and PEC36 series offer multiple post length variants: DAAN (0.120"), DABN (0.230"), DACN (0.320"), DAFN (0.620"), and DAHN (0.820"). These variations accommodate different PCB thicknesses and stack-up configurations while maintaining identical mating contact specifications. Verify PCB thickness requirements before selecting post length.

Q: Are all substitutes RoHS compliant?

A: The original 75844-150-72 is RoHS non-compliant. The direct equivalent 75844-150-72LF is RoHS compliant. All manufacturer-recommended alternatives from Sullins and Samtec carry ROHS3 compliance certification, suitable for applications requiring RoHS compliance.

Q: What is the current rating difference between substitutes?

A: The original part does not specify current rating. The 75844-150-72LF provides 5A rating. Sullins PBC36 and PEC36 series provide 3A rating. Samtec MTLW-136-08-G-D-273 provides the highest rating at 5.2A per contact. Application current requirements determine appropriate substitute selection.

Q: Can I use MTLW-136-08-G-D-273 as a direct substitute?

A: MTLW-136-08-G-D-273 maintains critical parameters including 72 positions, 2 rows, 0.100" pitch, male pins, and push-pull fastening. However, it differs in insulation height (0.060" versus 0.100"), overall contact length (0.530" versus 0.453"), and insulation material (liquid crystal polymer versus thermoplastic). These differences may affect PCB layout compatibility. Verify mechanical fit before substitution.

Q: What inventory levels are available for each substitute?

A: 75844-150-72LF: 844 pcs; GBC36DAAN: 805 pcs; MTLW-136-08-G-D-273: 1049 pcs; PBC36DAAN: 8210 pcs; PBC36DABN: 1136 pcs; PBC36DACN: 1328 pcs; PBC36DAFN: 1032 pcs; PBC36DAHN: 974 pcs; PEC36DAAN: 13229 pcs; PEC36DABN: 2009 pcs. PEC36DAAN offers the highest inventory availability.
