M22-2011505 Equivalent & Substitute Parts

Part Overview

The M22-2011505 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole board-to-board applications with 15 positions at 2.00mm pitch. This connector features a cuttable header design with unshrouded construction and push-pull fastening. The product is currently obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2011505 is determined by the following critical parameters:

Manufacturer series compatibility (M22 series)
Connector type and contact configuration (Header, Male Pin, Cuttable)
Pitch specification (2.00mm mating pitch)
Mounting method (Through Hole)
Termination type (Solder)
Electrical ratings (1A per contact minimum)
Environmental compliance (UL94 V-0, ROHS3, REACH Unaffected)
Operating temperature range (-55°C ~ 105°C)

The M22-2011646 qualifies as a substitute component within the M22 series. Both connectors share identical pitch, mounting type, termination method, contact material, insulation material, operating temperature range, current rating, and compliance certifications. The primary difference is the number of positions: the M22-2011505 provides 15 positions while the M22-2011646 provides 16 positions. This position difference allows the M22-2011646 to serve applications requiring additional contact capacity within the same physical and electrical framework.

Engineering Selection Recommendations

The M22-2011646 is the designated substitute for the obsolete M22-2011505. Both components maintain identical electrical and mechanical specifications across all critical parameters including pitch, mounting type, termination method, contact material, operating temperature range, and current rating. Both components satisfy ROHS3 compliance and REACH unaffected status.

The M22-2011646 is currently in active production status with 718 units available in inventory, whereas the M22-2011505 is obsolete. The M22-2011646 provides one additional contact position (16 versus 15), which accommodates expanded signal routing requirements within the same connector footprint and electrical framework.

The contact finish difference (gold on M22-2011505 versus tin on M22-2011646) reflects standard material specifications for active production components. Both finishes are compatible with standard PCB assembly and soldering processes.

Frequently Asked Questions (FAQ)

Q: Can the M22-2011646 directly replace the M22-2011505 in existing designs?

A: The M22-2011646 shares identical pitch, mounting type, termination method, contact material, insulation material, operating temperature range, and current rating specifications. The primary design consideration is the additional contact position (16 versus 15). If the application requires exactly 15 positions, the extra position on the M22-2011646 can be left unloaded or utilized for additional signal routing.

Q: What is the significance of the contact finish difference between these parts?

A: The M22-2011505 features gold plating on mating contacts, while the M22-2011646 features tin plating. Both finishes are suitable for standard PCB assembly and soldering processes. Tin plating is standard for active production components in this series.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. Both operate across the identical temperature range of -55°C to 105°C and support 1A per contact current rating.

Q: What is the packaging difference between these parts?

A: The M22-2011505 was supplied in standard packaging, while the M22-2011646 is supplied in bulk packaging. This reflects the active production status of the M22-2011646.

Q: Why is the M22-2011505 listed as obsolete?

A: The M22-2011505 has been discontinued by the manufacturer. The M22-2011646 represents the current production equivalent within the M22 series, offering the same core functionality with one additional contact position.
