M225-5202046 Equivalent & Substitute Parts

Part Overview

The M225-5202046 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole mounting applications requiring a 20-position, 2-row configuration with 2mm pitch. This connector features shrouded 4-wall design with male pin contacts and solder termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The M225-5202046 has been identified with one manufacturer-recommended substitute: M80-5002042. Substitution eligibility is determined by the following critical parameters that must remain consistent:

• Pitch - Mating: 0.079" (2.00mm) — ensures mechanical and electrical compatibility with mating connectors
• Number of Positions: 20 — maintains pin count and circuit connectivity
• Number of Rows: 2 — preserves board layout and spacing requirements
• Row Spacing - Mating: 0.079" (2.00mm) — critical for PCB footprint alignment
• Mounting Type: Through Hole — ensures compatibility with existing PCB designs
• Termination: Solder — maintains assembly process compatibility
• Shrouding: Shrouded - 4 Wall — preserves mechanical protection and polarization
• Contact Material: Phosphor Bronze — ensures electrical performance and durability
• Insulation Material: Polyphenylene Sulfide (PPS), Glass Filled — maintains thermal and chemical resistance
• Operating Temperature Range: -55°C ~ 125°C — ensures functional equivalence across environmental conditions
• Material Flammability Rating: UL94 V-0 — maintains safety compliance requirements

The substitute part M80-5002042 satisfies all critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The M80-5002042 is the manufacturer-recommended substitute for the obsolete M225-5202046. Both connectors maintain identical critical parameters for mechanical and electrical compatibility, including pitch, position count, row configuration, and operating temperature range.

The M80-5002042 offers the following advantages:

• Active Product Status: Currently in production with established supply chain and 5200 units in stock, compared to the obsolete M225-5202046 with limited remaining inventory
• Compliance Equivalence: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level
• Electrical Performance: The substitute maintains phosphor bronze contact material and polyphenylene sulfide insulation, ensuring equivalent durability and thermal performance across the -55°C to 125°C operating range

Differences in contact finish (gold vs. tin), current rating (2.2A vs. 3A), and fastening type (threaded vs. push-in) are secondary parameters that do not affect fundamental substitution eligibility when the primary mechanical and electrical parameters align.

Frequently Asked Questions (FAQ)

Q: Can M80-5002042 be used as a direct replacement for M225-5202046 in existing PCB designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (20), row configuration (2), and row spacing (2.00mm). The through-hole mounting type and solder termination are equivalent, allowing direct PCB footprint compatibility.

Q: What is the significance of the different contact finishes (tin vs. gold)?

A: Contact finish affects mating surface durability and corrosion resistance. Tin finish on the M225-5202046 and gold finish on the M80-5002042 both provide adequate protection for standard environmental conditions. The choice between them depends on specific application requirements for contact wear resistance and oxidation prevention.

Q: Does the lower current rating of M80-5002042 (2.2A vs. 3A) affect substitution eligibility?

A: The current rating difference must be evaluated against your circuit requirements. If the original design operates at or below 2.2A per contact, the substitute is fully compatible. If higher current is required, the substitute may not be suitable.

Q: What is the difference between "Plug" and "Header" connector types?

A: The M225-5202046 is classified as a plug (receptacle), while M80-5002042 is classified as a header (male connector). Both are male pin contact types and function equivalently in board-to-board or board-to-cable applications when mated with compatible receptacles.

Q: Are there packaging differences between these parts?

A: The M225-5202046 packaging is not specified in available data. The M80-5002042 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both connectors support the same mated stacking heights?

A: The M225-5202046 does not specify mated stacking heights. The M80-5002042 supports multiple stacking heights: 7.3mm, 7.7mm, 9.75mm, 10.75mm, 13.35mm, and 14.75mm. Confirm your application's stacking height requirement before final selection.
