Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2210646 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Male pin header for board-to-cable/wire connection
• Pitch & Position Count: 0.079" (2.00mm) pitch with 6 positions
• Mounting Orientation: Through-hole, right-angle mounting
• Electrical Performance: Current and voltage ratings must meet or exceed application requirements
• Termination Method: Solder-compatible termination for PCB integration
• Environmental Compliance: RoHS and REACH compliance status
• Operating Temperature Range: Must support the application's thermal requirements

The two substitute parts identified—M22-2030646 (Harwin Inc.) and 440055-6 (TE Connectivity)—share the core connector pitch, position count, and mounting type. However, each presents distinct trade-offs in shrouding design, contact material, current capacity, and fastening mechanism that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

M22-2030646 (Harwin Inc.) is an active product within the same manufacturer's M22 series. This substitute shares identical pitch, position count, and mounting orientation. However, the M22-2030646 features unshrouded construction compared to the 4-wall shrouding of the original part, and delivers reduced current capacity (1A per contact versus 2A). The extended operating temperature range (-55°C ~ 105°C) provides broader thermal coverage. This substitute is suitable for applications where shrouding is not critical and current requirements do not exceed 1A per contact. The cuttable header design offers additional flexibility for custom configurations.

440055-6 (TE Connectivity AMP Connectors) is an active product from a major connector manufacturer. This substitute maintains the same pitch, position count, and right-angle through-hole mounting. The 440055-6 provides superior current capacity (3A per contact) and voltage rating (250V), making it suitable for higher-power applications. The 3-wall shrouding offers intermediate protection compared to the original 4-wall design. Press-fit termination capability provides alternative assembly options alongside solder termination. Both substitute parts maintain RoHS compliance and UL94 V-0 flammability ratings, ensuring regulatory alignment with the original component.

Selection between substitutes depends on application-specific requirements: choose M22-2030646 for cost-optimized, lower-current designs within the extended temperature range; select 440055-6 for applications requiring higher current capacity and voltage performance.

Frequently Asked Questions (FAQ)

Q: Can M22-2030646 directly replace M22-2210646 in existing designs?

A: Direct replacement is possible only if application current requirements do not exceed 1A per contact and shrouding is not a functional requirement. The unshrouded design of M22-2030646 may affect EMI performance in sensitive applications. PCB layout verification is necessary to confirm mechanical compatibility.

Q: What are the key differences between the two substitute options?

A: M22-2030646 offers lower current capacity (1A) but extended temperature range (-55°C ~ 105°C) and cuttable header flexibility. 440055-6 provides higher current capacity (3A), higher voltage rating (250V), and intermediate shrouding (3-wall). Both maintain the same 2.00mm pitch and 6-position configuration.

Q: Is the 440055-6 suitable for applications originally designed for M22-2210646?

A: Yes, 440055-6 is functionally compatible for applications requiring the same pitch and position count. The higher current and voltage ratings provide design margin. The 3-wall shrouding differs from the original 4-wall design; verify that connector orientation and mating interface clearances are compatible with existing mating connectors.

Q: Are all substitute parts RoHS compliant?

A: Yes. M22-2030646 and 440055-6 are both RoHS compliant. M22-2030646 carries ROHS3 certification; 440055-6 carries RoHS certification. Both meet regulatory requirements for restricted substance elimination.

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

A: M22-2210646 and 440055-6 use brass contacts; M22-2030646 uses phosphor bronze. Phosphor bronze offers superior spring characteristics and wear resistance, while brass provides cost efficiency. For standard signal and power applications at the specified current levels, both materials are functionally equivalent.

Q: Can M22-2030646 be used in applications requiring the full 2A per contact rating?

A: No. M22-2030646 is rated for 1A per contact maximum. Applications requiring 2A per contact must use 440055-6 (3A rating) or source the original M22-2210646 from inventory if available.

Q: What are the packaging considerations for these substitutes?

A: M22-2210646 is available in limited new original stock (1104 pcs). M22-2030646 is available in bulk packaging (785 pcs in stock). 440055-6 is available in bulk packaging with the highest inventory level (3720 pcs). Bulk packaging typically offers cost advantages for production quantities.
