• Connector type: Plug, Male Pins
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Surface Mount, Right Angle
• Termination method: Solder
• Flange feature: Mating Side, Female Screwlock (4-40)
• Dielectric material: Polycyclohexylenedimethylene Terephthalate (PCT), Glass Filled
• Operating temperature range: -55°C ~ 105°C
• Contact finish: Gold
• Contact finish thickness: 31.5µin (0.80µm)

Allowable Variations:

• Shell material finish: Steel with different plating options (Tin Plated or Nickel Plated)
• Product status: Active alternatives acceptable for obsolete parts
• Additional features: Supplementary features such as mounting brackets do not preclude substitution
• Current rating specification: Presence of current rating in substitute does not affect compatibility

The substitute part 3-1740199-5 meets all mandatory matching parameters and represents a direct functional equivalent with active product status.

Parameter Comparison

Engineering Selection Recommendations

The 3-1740199-5 is a direct functional equivalent to the obsolete 3-1740199-2. Both connectors are manufactured by TE Connectivity within the AMPLIMITE HD-20 series and share identical electrical and mechanical specifications across all critical parameters.

Compliance and Certification Status: Both parts maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and storage requirements. The 3-1740199-5 carries active product status, providing assured long-term availability and supply chain continuity.

Shell Finish Variation: The primary difference between the two parts is the shell material finish: the 3-1740199-2 features tin plating, while the 3-1740199-5 features nickel plating. Both finishes are compatible with the gold-plated contact system and maintain equivalent environmental protection and electrical performance within the specified operating temperature range of -55°C to 105°C.

Feature Enhancement: The 3-1740199-5 includes mounting brackets as an additional feature not present in the 3-1740199-2. This enhancement does not affect substitution compatibility and provides supplementary mechanical support for surface mount applications.

For applications requiring the obsolete 3-1740199-2, the 3-1740199-5 provides direct substitution without design modification or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the 3-1740199-5 be used as a direct replacement for the 3-1740199-2 in existing designs?

A: Yes. The 3-1740199-5 is a direct functional equivalent. Both connectors share identical pin count (25 positions), shell size (DB, Size 3), mounting configuration (surface mount, right angle), termination method (solder), and operating specifications. No design modification is required.

Q: What is the difference between the tin-plated and nickel-plated shell finishes?

A: The 3-1740199-2 features a steel shell with tin plating, while the 3-1740199-5 features a steel shell with nickel plating. Both finishes provide equivalent corrosion resistance and environmental protection. The choice between them depends on application-specific environmental exposure and cost considerations. Both are compatible with the gold-plated contact system.

Q: Are both connectors RoHS compliant?

A: Yes. Both the 3-1740199-2 and 3-1740199-5 are RoHS compliant, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across the temperature range of -55°C to 105°C, suitable for industrial and commercial applications with extended thermal requirements.

Q: Does the addition of mounting brackets on the 3-1740199-5 affect compatibility?

A: No. The mounting brackets on the 3-1740199-5 are supplementary features that enhance mechanical support for surface mount applications. Their presence does not affect electrical or mechanical compatibility with mating connectors or PCB layouts designed for the 3-1740199-2.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Why is the 3-1740199-2 classified as obsolete?

A: Product obsolescence reflects TE Connectivity's manufacturing and inventory decisions. The 3-1740199-5 provides active product status with equivalent functionality, ensuring continued availability and supply chain support for applications previously using the 3-1740199-2.

Q: Are the contact finishes identical between the two parts?

A: Yes. Both connectors feature gold-plated contacts with identical finish thickness of 31.5µin (0.80µm), ensuring equivalent electrical performance and mating characteristics.
