3372-5202 Equivalent & Substitute Parts

Part Overview

The 3372-5202 is a rectangular connector header manufactured by 3M, designed for through-hole, right-angle board-to-board or cable applications. This 60-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and solder termination. The part is currently obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 3372-5202 is determined by strict equivalence across the following critical parameters:

Electrical & Mechanical Compatibility:

• 60-position connector with 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type
• Through-hole, right-angle mounting
• Shrouded 4-wall construction
• Solder termination
• 1.75A current rating
• -55°C ~ 105°C operating temperature range
• Gold mating contact finish
• UL94 V-0 flammability rating

Allowed Variations:

• Contact finish on post (Tin-Lead to Tin)
• Insulation material composition (PBT to PCT/Polyester, both glass-filled)
• Fastening mechanism (Latch Lock/Eject Hooks to Push-Pull)
• Product status transition (Obsolete to Active)
• RoHS compliance status
• Packaging format

The substitute N3372-5002RB maintains full electrical and mechanical compatibility while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The N3372-5002RB is the direct active equivalent for the obsolete 3372-5202. Selection of this substitute is based on the following engineering criteria:

Product Status: The 3372-5202 is obsolete. The N3372-5002RB maintains active product status, ensuring continued availability and manufacturer support.

Compliance & Certifications: The N3372-5002RB achieves RoHS compliance, whereas the original part is RoHS non-compliant. Both parts maintain UL94 V-0 flammability rating and REACH Unaffected status. For applications subject to RoHS regulations, the substitute is required.

Electrical & Mechanical Equivalence: All critical parameters—connector geometry, pitch, contact configuration, current rating, temperature range, and contact finish specifications—are identical between the two parts. The connector will function identically in existing PCB layouts and mating applications.

Material Composition: The insulation material differs (PBT to PCT/Polyester), but both are glass-filled thermoplastics with identical flammability ratings and operating temperature ranges. This variation does not affect electrical or mechanical performance.

Contact Finish: The post contact finish changes from Tin-Lead to Tin. This represents a lead-free transition and is compatible with modern soldering processes and environmental regulations.

Fastening Mechanism: The fastening type changes from Latch Lock/Eject Hooks to Push-Pull. Both mechanisms provide secure mating and are functionally equivalent for board-to-board or cable applications.

Frequently Asked Questions (FAQ)

Q: Can N3372-5002RB be used as a direct replacement for 3372-5202 in existing designs?

A: Yes. The N3372-5002RB is electrically and mechanically equivalent to the 3372-5202. All critical parameters—position count, pitch, mounting type, current rating, and operating temperature—are identical. The connector will mate with existing receptacles and function identically in the circuit.

Q: What is the difference in fastening mechanisms between these parts?

A: The 3372-5202 uses Latch Lock/Eject Hooks (short), while the N3372-5002RB uses Push-Pull fastening. Both mechanisms provide secure mating and disconnection. The choice between them depends on application requirements for mating force and user interface preference. Existing receptacles designed for one fastening type may not be compatible with the other.

Q: Why does the insulation material differ between the two parts?

A: The 3372-5202 uses polybutylene terephthalate (PBT), while the N3372-5002RB uses polycyclohexylenedimethylene terephthalate (PCT) or polyester. Both materials are glass-filled thermoplastics with identical UL94 V-0 flammability ratings and operating temperature ranges (-55°C ~ 105°C). The material change does not affect electrical or mechanical performance.

Q: What is the significance of the RoHS compliance difference?

A: The 3372-5202 is RoHS non-compliant due to tin-lead contact finish on the post. The N3372-5002RB is RoHS compliant with tin contact finish. For applications or markets requiring RoHS compliance, the N3372-5002RB is mandatory. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Are the contact finishes compatible with modern soldering processes?

A: The N3372-5002RB uses tin post finish, which is standard for lead-free soldering processes (SAC alloys). The 3372-5202 uses tin-lead finish, which is compatible with traditional lead-based soldering. Both are compatible with their respective soldering technologies. Ensure soldering process parameters match the contact finish specification.

Q: What is the packaging difference between these parts?

A: The 3372-5202 packaging is not specified in the data. The N3372-5002RB is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: Are there any PCB layout considerations when switching from 3372-5202 to N3372-5002RB?

A: No. Both connectors have identical mechanical dimensions, pitch, and mounting specifications. Existing PCB layouts require no modification. The only consideration is the fastening mechanism difference—ensure the mating receptacle is compatible with Push-Pull fastening if switching from the original Latch Lock design.
