Substitute Part Grouping Explanation

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

Pitch - Mating: 0.079" (2.00mm) — exact match required
Number of Positions: 44 — exact match required
Number of Rows: 2 — exact match required
Row Spacing - Mating: 0.079" (2.00mm) — exact match required
Mounting Type: Surface Mount — exact match required
Contact Type: Male Pin — exact match required
Termination: Solder — exact match required
Operating Temperature Range: -40°C ~ 105°C — minimum requirement
Material Flammability Rating: UL94 V-0 — minimum requirement
RoHS Status: ROHS3 Compliant — compliance requirement

The identified substitute parts meet these core electrical and mechanical parameters, enabling direct functional replacement in board-to-board connector applications.

Engineering Selection Recommendations

M22-5322205P (Harwin Inc.) is the primary substitute for the obsolete M22-5322246P. Both components are manufactured by Harwin Inc. within the M22 series, share identical electrical and mechanical specifications, and maintain active product status. The M22-5322205P is ROHS3 compliant and carries UL94 V-0 flammability certification, meeting all regulatory requirements. The primary difference is contact finish (gold versus tin), which does not affect functional compatibility for board-to-board applications.

0877597644 (Molex Milli-Grid 87759 series) serves as a cross-manufacturer substitute. This component matches all critical parameters including pitch, position count, row configuration, and mounting type. The contact length for mating is 0.150" (3.81mm) compared to 0.138" (4.60mm) in the Harwin parts, representing a 0.012" (0.31mm) difference. The Molex part features a breakaway connector type versus cuttable design and includes glass-filled nylon insulation. ROHS3 compliance and UL94 V-0 flammability rating are maintained. Operating temperature and current rating specifications are not provided for the Molex part.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical pitch (2.00mm), position count (44), row configuration (2 rows), mounting type (surface mount), and termination method (solder). The primary difference is contact finish (gold versus tin), which does not affect electrical or mechanical compatibility for board-to-board applications.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish affects corrosion resistance and contact reliability over time. Gold provides superior corrosion resistance and is preferred for high-reliability applications. Tin is suitable for standard industrial applications. Both finishes are compatible with solder termination.

Q: Is the Molex 0877597644 a suitable replacement?

A: The Molex part meets all critical electrical and mechanical parameters. The contact length difference (0.150" versus 0.138") and connector type variation (breakaway versus cuttable) must be evaluated against specific PCB design requirements. Verify mating height compatibility and breakaway functionality requirements before selection.

Q: What packaging options are available?

A: M22-5322205P is supplied in Tube packaging. The Molex 0877597644 is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both M22-5322205P and 0877597644 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.
