Substitute Part Grouping Explanation

The M80-8502645 qualifies as a direct substitute for the B5741-226-F-N-2 based on the following critical parameters:

• Connector Type & Configuration: Both are 26-position receptacle connectors with identical 0.079" (2.00mm) mating pitch and 2-row configuration
• Mechanical Interface: Both feature through-hole solder termination with locking ramp fastening, ensuring mechanical compatibility with existing PCB layouts
• Contact System: Both use circular beryllium copper contacts with gold plating on mating surfaces
• Thermal Performance: Both operate across the identical -55°C ~ 125°C temperature range
• Series Compatibility: Both belong to Harwin Inc.'s Datamate L-Tek series
• Regulatory Compliance: Both carry UL94 V-0 flammability rating and are REACH Unaffected

The M80-8502645 represents an active production alternative to the obsolete B5741-226-F-N-2, with enhanced compliance status and improved availability.

Frequently Asked Questions (FAQ)

Q: Can M80-8502645 be used as a direct replacement for B5741-226-F-N-2 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), row configuration (2 rows), position count (26), mounting type (through-hole), and fastening mechanism (locking ramp). PCB layouts and mating connector specifications require no modification.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), insulation material composition (polyester glass-filled vs. polyamide glass-filled), and contact post length (0.051" vs. 0.118"). These differences do not affect mechanical or electrical interchangeability for standard applications.

Q: Are there voltage or current rating differences?

A: The B5741-226-F-N-2 specifies 3A current rating and 120V voltage rating. The M80-8502645 specifies 800V voltage rating with no current rating provided in the data. The M80-8502645 supports higher voltage applications while maintaining compatibility with lower-voltage designs.

Q: What packaging is available for the M80-8502645?

A: The M80-8502645 is supplied in tube packaging, compared to the B5741-226-F-N-2 which had no specified packaging format.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do both parts meet the same regulatory standards?

A: Both achieve UL94 V-0 flammability rating, REACH Unaffected status, and EAR99 export classification. The M80-8502645 additionally achieves ROHS3 compliance, making it suitable for applications with environmental compliance requirements.
