Substitute Part Grouping Explanation

Substitution eligibility for the M22-5322346 is determined by the following critical parameters:

Pitch and Row Spacing: 0.079" (2.00mm) mating pitch and row spacing are fundamental to mechanical compatibility
Connector Type: Header, cuttable configuration for board-to-board applications
Contact Type: Male pin configuration
Mounting Type: Surface mount technology
Termination Method: Solder termination
Operating Temperature Range: -40°C ~ 105°C
Current Rating: 1A per contact minimum
Series Compatibility: M22 series from Harwin Inc.

The M22-5322505 qualifies as a substitute based on matching these core parameters. The primary difference is an increase in position count from 46 to 50 positions, which represents a functional extension rather than a deviation from the established parameter set. Both components maintain identical pitch, row spacing, mounting type, termination method, and operating temperature specifications.

Engineering Selection Recommendations

The M22-5322505 is the designated substitute for the obsolete M22-5322346. Selection of this substitute is supported by the following factors:

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Product Status: The M22-5322505 carries active product status, providing assured availability and ongoing manufacturer support, whereas the M22-5322346 is obsolete.

Electrical and Mechanical Compatibility: The substitute maintains identical electrical specifications (1A per contact), mechanical pitch (2.00mm), row spacing (2.00mm), mounting configuration (surface mount), and operating temperature range (-40°C ~ 105°C).

Position Count Consideration: The increase from 46 to 50 positions represents a functional extension. Applications utilizing fewer than 46 positions can employ the M22-5322505 with unused positions left unloaded or cut away, consistent with the cuttable header design.

Frequently Asked Questions (FAQ)

Q: Can the M22-5322505 be used as a direct replacement for the M22-5322346?

A: Yes, the M22-5322505 qualifies as a substitute. Both components share identical pitch (2.00mm), row spacing (2.00mm), contact type (male pin), mounting type (surface mount), and operating temperature range (-40°C ~ 105°C). The primary difference is the increased position count from 46 to 50.

Q: What is the significance of the position count difference?

A: The M22-5322505 provides 50 positions compared to 46 in the original part. For applications requiring exactly 46 positions, the additional 4 positions can remain unloaded or the connector can be cut to the required length, as both components feature cuttable header design.

Q: Are there any differences in contact finish between these parts?

A: Yes. The M22-5322346 features tin contact finish on both mating and post surfaces. The M22-5322505 specifies gold contact finish on mating surfaces. Both finishes are compatible with solder termination and maintain the same current rating of 1A per contact.

Q: What is the packaging difference?

A: The M22-5322346 is listed with no specified packaging designation, while the M22-5322505 is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Are both components suitable for the same operating temperature range?

A: Yes. Both the M22-5322346 and M22-5322505 operate across the identical temperature range of -40°C to 105°C.

Q: What is the moisture sensitivity level for these connectors?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
