Key Parameters

Substitute Part Grouping Explanation

The M80-7530442 qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Both parts maintain identical 4-position, 2-row arrangement with 0.079" (2.00mm) pitch spacing
• Mechanical Interface: Matching shrouded 4-wall design, through-hole mounting, and latch lock fastening ensure physical compatibility
• Electrical Specifications: Both rated for 2.2A current and operate across -55°C to 125°C temperature range
• Contact System: Identical phosphor bronze material with gold-plated mating contacts and tin-lead or tin post finishes
• Compliance: Both parts maintain ROHS3 compliance and EAR99 classification

The primary distinction is product status: M80-8550422 is obsolete, while M80-7530442 is active production. The substitute features enhanced voltage rating (800V vs. 120V) and improved insulation material (PPS vs. polyester), providing superior performance characteristics while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M80-7530442 is the designated manufacturer substitute for the obsolete M80-8550422. Selection of the active part is supported by:

• Product Continuity: M80-7530442 maintains active production status with documented inventory availability (1861 pcs), ensuring long-term supply chain reliability
• Regulatory Compliance: Both parts maintain identical ROHS3 and REACH compliance certifications, with matching UL94 V-0 flammability ratings
• Enhanced Specifications: The substitute provides superior voltage rating (800V vs. 120V) and improved insulation material (PPS vs. polyester), delivering enhanced performance margins without compromising compatibility
• Mechanical Compatibility: Identical pitch, row spacing, shrouding configuration, and fastening mechanisms ensure direct physical interchangeability in existing PCB layouts

Frequently Asked Questions (FAQ)

Q: Can M80-7530422 directly replace M80-8550422 in existing designs?

A: Yes. Both parts share identical mechanical interfaces (4-position, 2-row, 2mm pitch, shrouded 4-wall design) and electrical ratings (2.2A, -55°C to 125°C operation). The substitute is mechanically and electrically compatible with existing PCB layouts and mating connectors.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), connector designation (plug vs. header), voltage rating (120V vs. 800V), and insulation material (polyester vs. PPS). The substitute offers enhanced voltage capability and improved thermal/chemical resistance through superior insulation material.

Q: Are there packaging differences?

A: M80-8550422 packaging is not specified in available documentation. M80-7530442 is supplied in tube packaging. Confirm packaging requirements with procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability. Both carry EAR99 export classification.

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

A: Both parts feature gold-plated mating contacts (29.5µin/0.75µm thickness). Post contact finish differs: M80-8550422 uses tin-lead, while M80-7530442 uses tin. Both maintain 118.1µin (3.00µm) post finish thickness.
