Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-5322246R is determined by strict alignment of the following critical parameters:

• Connector pitch: 0.079" (2.00mm) mating pitch and row spacing
• Position count and row configuration: 44 positions in 2-row arrangement
• Mounting technology: Surface mount termination
• Contact type: Male pin configuration
• Current capacity: 1A per contact minimum
• Operating temperature range: -40°C to 105°C minimum
• Series compatibility: M22 series connectors
• Mechanical interface: Board-to-board style, unshrouded, push-pull fastening

The M22-5322205R qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The M22-5322205R is the qualified substitute for the obsolete M22-5322246R. Both parts maintain identical mechanical and electrical specifications across all critical parameters including pitch, position count, current rating, and operating temperature range.

The primary distinction is product status: M22-5322246R is obsolete while M22-5322205R is active production. The M22-5322205R features gold contact finish on mating surfaces compared to tin finish on the original part, which provides enhanced corrosion resistance and contact reliability. Both parts carry equivalent compliance certifications: ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status.

For new designs or ongoing procurement, M22-5322205R is the appropriate selection. The substitute is available in tape and reel packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can M22-5322205R directly replace M22-5322246R in existing designs?

A: Yes. The M22-5322205R is mechanically and electrically identical to M22-5322246R across all critical parameters: pitch, position count, row configuration, contact type, current rating, and operating temperature range. Both parts are unshrouded, surface mount, board-to-board connectors within the M22 series.

Q: What is the difference between the contact finishes?

A: M22-5322246R uses tin contact finish on mating surfaces, while M22-5322205R uses gold contact finish. Gold provides superior corrosion resistance and contact reliability in demanding environments. Both finishes support the same 1A per contact current rating and operating temperature range.

Q: Why is M22-5322246R listed as obsolete?

A: Product obsolescence is determined by manufacturer production status. M22-5322205R is the active production equivalent and is the recommended selection for all new applications and ongoing procurement.

Q: Are there packaging differences between these parts?

A: M22-5322246R packaging is not specified in available data. M22-5322205R is supplied in tape and reel (TR) packaging, which is standard for automated surface mount assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M22-5322246R and M22-5322205R are ROHS3 compliant, carry UL94 V-0 flammability rating, and are REACH unaffected. Moisture sensitivity level is 1 (unlimited) for both parts.
