Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0533534071 is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts
• Position Count: 40 positions
• Pitch Configuration: 0.031" (0.80mm)
• Row Configuration: 2 rows
• Mounting Technology: Surface mount
• Contact Material: Tin finish
• Compliance Standards: ROHS3 and REACH requirements

The Molex 0533074071 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both components share identical position count, pitch, row configuration, mounting type, and contact finish specifications. The substitute part is from the SlimStack 53307 series and maintains full compliance with applicable regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0533074071 is the manufacturer-recommended substitute for the discontinued 0533534071. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The substitute part is currently in active production with higher inventory availability (2182 pcs) compared to the original part status. The primary dimensional difference is the reduced height above board (0.144" versus 0.242"), which may require PCB layout verification for clearance-critical applications.

Both parts carry MSL rating 1 (unlimited moisture sensitivity), ensuring equivalent handling and storage requirements. Contact finish thickness is specified for the substitute part at 120.0µin (3.05µm), providing documented durability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0533074071 be used as a direct replacement for the 0533534071?

A: Yes. Both parts share identical electrical specifications: 40 positions, 0.031" (0.80mm) pitch, 2-row configuration, surface mount technology, and tin contact finish. The substitute is manufacturer-recommended and maintains equivalent compliance certifications.

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

A: The height above board differs: the original measures 0.242" (6.15mm) while the substitute measures 0.144" (3.66mm). This dimensional change must be evaluated against PCB layout constraints and mating component clearances.

Q: Are there packaging differences between the original and substitute?

A: The substitute part is supplied in Tape & Reel (TR) packaging, whereas the original part packaging is not specified. Packaging format may affect procurement, handling, and assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0533534071 and 0533074071 are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory requirements.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL rating 1 (unlimited), indicating no moisture sensitivity restrictions for storage or handling.
