Substitute Part Grouping Explanation

Substitution eligibility for the M22-6361946 is determined by the following critical parameters:

Connector Configuration: Receptacle, 38 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
Mounting Method: Surface mount with solder termination
Fastening Mechanism: Push-pull engagement
Contact Specifications: Female socket, square contact shape, phosphor bronze material
Electrical Performance: 2A current rating minimum, UL94 V-0 flammability rating
Environmental Compliance: ROHS3 compliance, MSL 1 (Unlimited)

Substitute parts must maintain these core parameters. Variations in contact finish (tin to gold), insulation material, operating temperature range, and current rating per contact are permitted when the primary electrical and mechanical interface requirements are satisfied.

Engineering Selection Recommendations

M22-6362142R (Harwin Inc.): This part maintains the same manufacturer lineage as the original M22-6361946 and shares identical pitch, row configuration, and mounting specifications. The primary difference is the 42-position count versus 38 positions. This part is active and ROHS3 compliant, making it suitable for new designs requiring Harwin M22 series compatibility. The gold contact finish provides enhanced corrosion resistance compared to the original tin plating.

55508-138LF (Amphenol ICC/FCI): This Minitek 2.00mm series connector matches the 38-position, 2-row configuration and 0.079" pitch of the original part. It maintains 2A current rating and UL94 V-0 flammability compliance. The extended operating temperature range (-55°C to 125°C) and gold plating offer performance advantages. This part is active and RoHS compliant, providing direct functional equivalence for board-to-board applications.

CLT-119-02-L-D (Samtec Inc.): This CLT series connector provides 38-position, 2-row configuration with 0.079" pitch and push-pull fastening. It is currently active and ROHS3 compliant. The higher current rating (4.1A per contact) and extended temperature range (-55°C to 125°C) exceed the original specifications. Liquid crystal polymer insulation material offers improved dimensional stability. This part is recommended for applications requiring enhanced electrical performance and environmental robustness.

CLT-119-02-G-D (Samtec Inc.): This variant shares the same core specifications as CLT-119-02-L-D but is discontinued at DiGi Electronics. While technically equivalent, its discontinued status limits availability for production applications. Selection should prioritize CLT-119-02-L-D for active supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can M22-6362142R be used as a direct replacement for M22-6361946?

A: M22-6362142R is mechanically and electrically compatible for applications using 38 or fewer positions. The 42-position configuration accommodates the original 38-position requirement. Both parts share identical pitch (0.079"), row spacing, surface mount configuration, and push-pull fastening. The gold contact finish of M22-6362142R provides superior corrosion resistance compared to the original tin plating.

Q: What is the primary difference between tin and gold contact finishes?

A: Contact finish affects corrosion resistance and mating force characteristics. Tin plating (M22-6361946) is cost-effective for general applications. Gold plating (M22-6362142R, 55508-138LF, CLT-119-02-L-D, CLT-119-02-G-D) provides enhanced corrosion resistance and is preferred for high-reliability, long-term storage, or harsh environmental applications. Both finishes are electrically equivalent for the specified 2A current rating.

Q: Are Samtec CLT series connectors compatible with Harwin M22 series?

A: CLT-119-02-L-D and CLT-119-02-G-D are not mechanically interchangeable with M22 series connectors due to different insulation body designs and contact geometries. However, they provide functional equivalence when mated with compatible plug connectors of the same series. Verify mating connector compatibility before substitution.

Q: Which substitute part offers the best performance upgrade?

A: CLT-119-02-L-D provides the highest performance specification with 4.1A per contact current rating (versus 2A original), extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), and liquid crystal polymer insulation for improved dimensional stability. This part is active and ROHS3 compliant.

Q: Is the position count difference between M22-6361946 (38 positions) and M22-6362142R (42 positions) a compatibility issue?

A: The 42-position M22-6362142R accommodates the original 38-position requirement. Unused positions do not affect electrical or mechanical performance. This substitution is valid when the application circuit design can accommodate the additional positions or when they remain unpopulated.

Q: What compliance certifications are maintained across all substitute parts?

A: All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance (ROHS3 or equivalent). All parts carry MSL 1 (Unlimited) moisture sensitivity level. These certifications ensure compatibility with industrial, telecommunications, and general-purpose applications specified for the original M22-6361946.
