M22-2015046 Equivalent & Substitute Parts

Part Overview

The M22-2015046 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole mounting applications. This 50-position, single-row connector operates at 0.079" (2.00mm) pitch and supports 1A per contact with an operating temperature range of -55°C to 105°C. The part is classified as obsolete, making identification of active equivalent components necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2015046 is determined by the following critical parameters:

Pitch and Position Count: All substitutes must maintain 0.079" (2.00mm) mating pitch with 50 positions in a single row to ensure PCB footprint compatibility.
Connector Type and Contact Configuration: Header connectors with male pins and through-hole solder termination are required.
Electrical Performance: Current rating and operating temperature range must meet or exceed the original specification.
Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating are mandatory for equivalent substitution.
Mounting and Termination: Through-hole solder termination is non-negotiable for board-level integration.

Two active substitutes meet these criteria: M22-2015005 (Harwin Inc.) and TMM-150-01-G-S (Samtec Inc.).

Engineering Selection Recommendations

M22-2015005 (Harwin Inc.) is the primary substitute for the M22-2015046. Both components are manufactured by Harwin Inc. within the M22 series, share identical mechanical and electrical specifications, and maintain full compliance with ROHS3 and UL94 V-0 standards. The M22-2015005 is currently in active production with higher inventory availability (1227 pcs vs. 753 pcs). The contact finish differs (gold vs. tin), which provides improved corrosion resistance and contact reliability in the substitute.

TMM-150-01-G-S (Samtec Inc.) serves as an alternative substitute when M22-2015005 is unavailable. This component maintains the same pitch, position count, and through-hole solder termination. The TMM-150-01-G-S offers enhanced electrical performance with a 3.2A per contact rating (versus 1A) and an extended operating temperature range to 125°C. The insulation material differs (Liquid Crystal Polymer vs. Polyamide), and the flammability rating is not specified in available documentation. This substitute is suitable for applications requiring higher current capacity or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can M22-2015005 be used as a direct replacement for M22-2015046?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (50), row configuration (1), mounting type (through-hole), and termination method (solder). Mechanical and electrical compatibility is confirmed. The primary difference is contact finish (gold vs. tin) and active product status.

Q: What are the key differences between M22-2015005 and TMM-150-01-G-S?

A: Both maintain the required 0.079" pitch and 50-position configuration. TMM-150-01-G-S provides higher current capacity (3.2A vs. 1A per contact) and extended operating temperature (-55°C to 125°C vs. -55°C to 105°C). Insulation material differs: M22-2015005 uses Polyamide (PA6T), while TMM-150-01-G-S uses Liquid Crystal Polymer (LCP). The TMM-150-01-G-S flammability rating is not documented.

Q: Are all substitutes RoHS3 compliant?

A: Yes. Both M22-2015005 and TMM-150-01-G-S are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Does contact finish affect compatibility?

A: Contact finish (tin vs. gold) does not affect mechanical compatibility or basic electrical function. Gold plating provides superior corrosion resistance and contact reliability, particularly in environments with moisture or corrosive atmospheres. Tin plating is suitable for standard applications with adequate environmental protection.

Q: Which substitute should be selected for high-current applications?

A: TMM-150-01-G-S is specified for 3.2A per contact, compared to 1A for both M22-2015046 and M22-2015005. Selection depends on circuit current requirements and thermal management considerations.

Q: Are there packaging differences between substitutes?

A: M22-2015005 is supplied in bulk packaging. TMM-150-01-G-S is also supplied in bulk packaging. Both are suitable for standard procurement and assembly workflows.
