M22-5330705 Equivalent & Substitute Parts

Part Overview

The M22-5330705 is a surface mount, right-angle rectangular connector header manufactured by Harwin Inc. in the M22 series. This 7-position connector operates at 2.00mm pitch with male pin contacts, gold-plated mating surfaces, and a current rating of 2A per contact. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-5330705 is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 7 positions — determines connector footprint and contact count
• Mounting Type: Surface Mount, Right Angle — defines PCB assembly method and orientation
• Contact Type: Male Pin — specifies mating interface
• Connector Style: Board to Board or Cable — establishes application compatibility
• Termination: Solder — defines connection method to PCB

Substitute parts are grouped into two categories:

Category A: Direct Functional Equivalents (Same Position Count)

• MMT-107-01-S-SH-A-P-TR (Samtec Inc.)
• MMT-107-01-T-SH-P-TR (Samtec Inc.)

These parts maintain identical position count (7), pitch (2.00mm), mounting type (surface mount, right angle), and contact type (male pin), ensuring direct mechanical and electrical compatibility.

Category B: Harwin Series Alternative (Different Position Count)

• M22-5331405 (Harwin Inc.)

This part shares the same manufacturer, series, pitch, and mounting characteristics but provides 14 positions. Selection depends on application requirements for expanded contact capacity within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (7-Position Requirement):

The Samtec MMT-107 series connectors (MMT-107-01-S-SH-A-P-TR and MMT-107-01-T-SH-P-TR) provide active product alternatives to the obsolete M22-5330705. Both maintain the critical 7-position, 2.00mm pitch, surface mount right-angle configuration.

MMT-107-01-S-SH-A-P-TR offers gold-plated mating contacts with extended temperature range (-55°C ~ 125°C) and higher current capacity (3A per contact). This variant is suitable for applications requiring enhanced thermal performance and current handling.

MMT-107-01-T-SH-P-TR features tin-plated mating contacts with operating temperature range of -55°C ~ 105°C and 3A current rating. This variant is appropriate for cost-optimized designs where gold plating is not required.

Both Samtec alternatives employ Liquid Crystal Polymer (LCP) insulation and Phosphor Bronze contacts, differing from the original Brass/Polyamide construction. All parts maintain UL94 V-0 flammability rating and ROHS3 compliance.

For Harwin Series Continuity (14-Position Alternative):

The M22-5331405 maintains manufacturer continuity within the Harwin M22 series and shares identical pitch, mounting type, and material specifications with the original part. This option is applicable when design requirements permit increased position count or when maintaining single-manufacturer sourcing is preferred.

Frequently Asked Questions (FAQ)

Q: Can MMT-107-01-S-SH-A-P-TR and MMT-107-01-T-SH-P-TR be used interchangeably with M22-5330705?

A: Both Samtec connectors maintain the same 7-position count, 2.00mm pitch, surface mount right-angle configuration, and male pin contact type as the original part. Mechanical and electrical compatibility is established. Differences in contact material (Phosphor Bronze vs. Brass), insulation material (LCP vs. Polyamide), and contact finish (Gold or Tin vs. Gold Flash) must be evaluated against specific application requirements.

Q: What is the difference between MMT-107-01-S-SH-A-P-TR and MMT-107-01-T-SH-P-TR?

A: The primary difference is contact finish: MMT-107-01-S-SH-A-P-TR features gold-plated mating contacts (30.0µin thickness), while MMT-107-01-T-SH-P-TR uses tin plating. Both provide 3A current capacity and support the same temperature range of -55°C ~ 105°C, except MMT-107-01-S-SH-A-P-TR extends to 125°C maximum.

Q: Why does M22-5331405 have 14 positions instead of 7?

A: M22-5331405 is a different connector variant within the same Harwin M22 series, designed for applications requiring double the contact count. It is not a direct replacement but an alternative within the same product family, maintaining identical pitch and mounting characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. M22-5330705, MMT-107-01-S-SH-A-P-TR, MMT-107-01-T-SH-P-TR, and M22-5331405 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the impact of different contact materials on performance?

A: The original M22-5330705 uses Brass contacts, while Samtec alternatives employ Phosphor Bronze. Phosphor Bronze provides enhanced spring properties and wear resistance. Both materials are suitable for 2.00mm pitch connectors with the specified current ratings. Material selection should align with mating cycle requirements and contact force specifications for the application.

Q: Can the M22-5331405 be used if only 7 positions are needed?

A: M22-5331405 is a 14-position connector. While it shares the same pitch and mounting type, using a 14-position connector in an application requiring only 7 positions introduces unnecessary complexity and cost. Direct 7-position alternatives (Samtec MMT-107 series) are recommended for this scenario.
