Key Parameters

Substitute Part Grouping Explanation

The M80-8400745 qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both are 7-position receptacle connectors with female socket contacts
• Pitch Specification: Identical 0.079" (2.00mm) mating pitch ensures mechanical and electrical compatibility with corresponding plug connectors
• Mounting & Termination: Both use through-hole solder termination with locking ramp fastening
• Contact Material & Finish: Both feature beryllium copper contacts with gold plating on mating surfaces
• Electrical & Environmental Ratings: Both operate across -55°C to 125°C temperature range and maintain UL94 V-0 flammability compliance
• Series Continuity: Both belong to Harwin Inc.'s Datamate L-Tek series

The M80-8400745 represents the active production equivalent, with enhanced specifications including higher voltage rating (800V vs. 120V) and improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The M80-8400745 is the recommended active production substitute for the obsolete B5741-107-F-N-2. Selection is based on the following engineering criteria:

Product Status: The B5741-107-F-N-2 is obsolete, while M80-8400745 maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: M80-8400745 achieves ROHS3 compliance, meeting current environmental regulations. The original part carries RoHS non-compliant status, which may present procurement restrictions in regulated markets.

Electrical Performance: M80-8400745 provides enhanced voltage rating (800V) compared to the original specification (120V), offering superior electrical margin for applications requiring higher voltage tolerance.

Mechanical Compatibility: Both connectors maintain identical pitch (0.079"), contact configuration (7-position female socket), mounting method (through-hole), and fastening mechanism (locking ramp), ensuring direct mechanical interchangeability.

Material & Environmental Specifications: Both parts utilize beryllium copper contacts with gold plating and maintain identical operating temperature range (-55°C to 125°C) and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can M80-8400745 directly replace B5741-107-F-N-2 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), contact configuration (7-position female socket), mounting type (through-hole), and fastening mechanism (locking ramp). Mechanical and electrical interchangeability is confirmed across all critical parameters.

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

A: The primary differences are product status (obsolete vs. active), regulatory compliance (RoHS non-compliant vs. ROHS3 compliant), and voltage rating (120V vs. 800V). The M80-8400745 represents the current production equivalent with enhanced specifications.

Q: Does the higher voltage rating of M80-8400745 affect compatibility?

A: No. Higher voltage rating indicates improved electrical capability and does not compromise compatibility. Applications designed for 120V operation remain fully compatible with the 800V-rated substitute.

Q: Are there packaging differences between these parts?

A: The B5741-107-F-N-2 packaging specification is not provided. The M80-8400745 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the significance of ROHS3 compliance on M80-8400745?

A: ROHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. This is essential for applications subject to environmental compliance requirements or export to regulated markets.

Q: Are the insulation materials compatible between these connectors?

A: Both connectors maintain identical insulation height (0.202" / 5.14mm) and color (black). Insulation material differs (polyester glass-filled vs. polyamide glass-filled), but both meet UL94 V-0 flammability requirements and maintain functional compatibility.
