Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-2740746 is determined by strict equivalence across the following electrical and mechanical parameters:

• Pitch and Position Configuration: 2.00mm mating pitch with 14 positions in a 2-row arrangement
• Connector Type and Mounting: Header connector with through-hole, right-angle mounting
• Contact Specifications: Male pin contacts with square shape, phosphor bronze material, and tin finish
• Electrical Performance: 2A current rating and -40°C to 105°C operating temperature range
• Material and Compliance: Polyamide (PA6T) insulation, UL94 V-0 flammability rating, and ROHS3 compliance

The M22-2540746 qualifies as a direct substitute based on these parameters. Both parts share identical pitch, position count, row configuration, contact type, current rating, temperature range, and material specifications. The primary distinction is product status: M22-2540746 is active, whereas M22-2740746 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M22-2540746 is the direct active equivalent for the obsolete M22-2740746. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in applications requiring 14-position, 2.00mm pitch rectangular connectors with through-hole right-angle mounting.

Selection of M22-2540746 is supported by:

• Product Status: Active manufacturing status ensures ongoing availability and supply chain continuity
• Compliance Certifications: ROHS3 compliance and UL94 V-0 flammability rating meet current regulatory requirements
• Electrical and Thermal Performance: Identical current rating (2A) and operating temperature range (-40°C to 105°C) maintain design compatibility
• Material Specifications: Matching insulation material, contact composition, and finish specifications preserve electrical and mechanical performance

Frequently Asked Questions (FAQ)

Q: Can M22-2540746 be used as a direct replacement for M22-2740746?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters: 14-position configuration, 2.00mm pitch, 2-row arrangement, male pin contacts, 2A current rating, and -40°C to 105°C operating temperature. The primary difference is product status; M22-2540746 is active while M22-2740746 is obsolete.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in pitch (2.00mm), position count (14), row configuration (2 rows), connector type (header with right-angle through-hole mounting), contact type (male pin), current rating (2A), operating temperature range (-40°C to 105°C), and material specifications (phosphor bronze contacts, polyamide insulation, tin finish).

Q: Are there packaging differences between these parts?

A: M22-2740746 packaging information is not specified in available data. M22-2540746 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current compliance standards?

A: Yes. Both M22-2740746 and M22-2540746 are ROHS3 compliant and carry UL94 V-0 flammability ratings. Both have MSL 1 (Unlimited) moisture sensitivity classification.

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

A: Contact length at mating differs: M22-2740746 has 0.165" (4.20mm) mating contact length, while M22-2540746 has 0.138" (4.60mm). Both maintain identical post contact length of 0.094" (2.40mm) and insulation height of 0.157" (4.00mm). Verify mating contact length compatibility with your mating connector specifications.
