Key Parameters

Substitute Part Grouping Explanation

The substitute part 5223995-2 is identified as a functionally compatible alternative based on the following critical parameters:

Matching Parameters:

• Connector style: Blade Power configuration
• Number of positions: 5-position connector
• Mounting type: Through-hole PCB mounting
• Termination method: Press-fit contact system
• Operating temperature range: -55°C to 125°C
• Contact finish: Gold or Gold-Palladium
• RoHS3 compliance and REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Functional Relationship: The 244995 is a male pin header, while the 5223995-2 is a female receptacle connector. These components form complementary mating pairs within blade power connector systems. Both components share identical pitch spacing (2.00mm), position count, and environmental operating specifications, enabling them to function as interconnected elements in backplane applications.

Parameter Comparison

Engineering Selection Recommendations

The 5223995-2 represents an active product alternative to the obsolete 244995. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The 5223995-2 maintains active production status within the TE Connectivity AMP Connectors product line, ensuring continued availability and supply chain stability compared to the obsolete 244995.

Compliance Equivalence: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement. Moisture sensitivity level 1 classification indicates unlimited shelf life for both parts.

Environmental Operating Specifications: Identical operating temperature ranges (-55°C to 125°C) confirm thermal compatibility across industrial and commercial applications.

Connector System Compatibility: The blade power connector style, 5-position configuration, and 2.00mm pitch spacing establish mechanical and electrical compatibility within backplane connector systems. The male-to-female complementary relationship enables direct mating functionality.

Contact System Specifications: Gold or Gold-Palladium contact finish on the 5223995-2 provides equivalent or superior contact reliability compared to the gold-finished 244995, with no degradation in electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 5223995-2 directly replace the 244995 in existing designs?

A: The 5223995-2 is a female receptacle connector, while the 244995 is a male header. These components are complementary mating pairs, not direct one-to-one replacements. The 5223995-2 is selected when a receptacle connector is required in the system design. Both components operate within identical electrical and mechanical specifications for blade power backplane applications.

Q: What is the significance of the pitch specification in connector selection?

A: Pitch (0.079" or 2.00mm) defines the center-to-center spacing between connector positions. Both the 244995 and 5223995-2 operate at 2.00mm pitch, ensuring mechanical alignment and proper mating within blade power connector systems. Pitch mismatch prevents proper connector engagement.

Q: How does the obsolete status of the 244995 affect component procurement?

A: Obsolete status indicates the 244995 is no longer in active production. The 5223995-2, classified as active, provides continued supply availability. For applications requiring male pin headers in blade power configurations, alternative male connector options within the active TE Connectivity product portfolio should be evaluated.

Q: Are there temperature or voltage limitations when using these connectors?

A: Both components operate across -55°C to 125°C. The 5223995-2 specifies a 250V voltage rating. The 244995 does not specify a voltage rating in available documentation. Applications requiring voltage specification confirmation should reference complete technical datasheets.

Q: What does press-fit termination mean for PCB assembly?

A: Press-fit termination indicates contacts are mechanically inserted into PCB plated through-holes under controlled pressure, creating a permanent mechanical and electrical connection without solder. Both the 244995 and 5223995-2 utilize this termination method, enabling automated assembly processes.

Q: How does the contact finish affect connector performance?

A: Gold and Gold-Palladium finishes provide corrosion resistance and reliable electrical contact over the operating temperature range. The 5223995-2 offers Gold or Gold-Palladium options, providing equivalent or enhanced contact reliability compared to the gold-finished 244995.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 classification indicates unlimited shelf life with no moisture absorption restrictions. Both components can be stored and handled without special moisture control measures, simplifying inventory management and reducing procurement complexity.
