L77HDBH44SOL2

Part Overview

The L77HDBH44SOL2 is a 44-position D-Sub High Density receptacle connector manufactured by Amphenol ICC (Commercial Products). This female sockets connector features vertical solder termination and is designed for applications requiring high-density signal interconnection. The product maintains Active status with full RoHS compliance and unlimited moisture sensitivity rating. Alternative models become necessary when application requirements demand different mounting configurations, such as panel mount options, or when alternative supplier options provide equivalent electrical and mechanical performance with improved availability or cost considerations.

Key Parameters

Substitute Part Grouping Explanation

The identified substitute part, 180-044-213R911 from NorComp Inc., shares the critical electrical and mechanical parameters that define functional equivalence for D-Sub High Density 44-position receptacle connectors:

Critical Matching Parameters:

• Number of Positions: 44
• Number of Rows: 3
• Connector Type: Receptacle, Female Sockets
• Shell Size, Connector Layout: 3 (DB, B) High Density
• Contact Type: Signal
• Termination: Solder
• Contact Material: Brass
• Contact Finish: Gold, Flash
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• RoHS Status: Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

Differences in Configuration: The substitute part incorporates additional mounting flexibility through panel mount capability and includes board lock and shielded features. The shell material differs (nickel plated vs. tin plated), and the dielectric material is polybutylene terephthalate (PBT) rather than thermoplastic glass-filled material. The operating temperature range is -50°C to 100°C compared to -55°C to 105°C on the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the L77HDBH44SOL2 and 180-044-213R911 maintain Active product status with full compliance certifications (RoHS, REACH Unaffected, EAR99). Selection between these parts depends on application-specific mounting requirements and environmental operating conditions.

The L77HDBH44SOL2 is suitable for applications requiring the extended operating temperature range of -55°C to 105°C, and applications where through-hole vertical mounting from Amphenol ICC is the specified standard. This part maintains tinned steel shell finish with glass-filled thermoplastic dielectric material.

The 180-044-213R911 provides equivalent electrical performance with the addition of panel mount capability and board lock features. This substitute is appropriate when panel mounting configuration is required or when additional mechanical shielding is beneficial. The operating temperature range limitation to -50°C to 100°C must be evaluated against specific application requirements. The ROHS3 compliance designation indicates alignment with current regulatory standards.

Both parts meet identical signal transmission requirements, current ratings, and moisture sensitivity specifications, supporting direct functional substitution within their respective mechanical mounting constraints.

Frequently Asked Questions (FAQ)

Q: Can 180-044-213R911 be used as a direct replacement for L77HDBH44SOL2 in through-hole applications?

A: The 180-044-213R911 supports through-hole mounting in addition to panel mount, so it can be used in through-hole applications. However, the operating temperature range is restricted to -50°C to 100°C versus the original part's -55°C to 105°C. Verify that your application does not require operation at temperatures below -50°C or above 100°C.

Q: Are there electrical performance differences between these connectors?

A: No. Both parts share identical current ratings (3A), voltage rating specifications, contact finish (gold flash), contact material (brass), and flammability ratings (UL94 V-0). They are electrically equivalent for signal transmission applications.

Q: What is the significance of the different shell finishes (tin vs. nickel plated)?

A: Both finishes provide corrosion protection and are suitable for signal-level applications with 3A current ratings. The tin-plated finish on the L77HDBH44SOL2 and nickel-plated finish on the 180-044-213R911 offer equivalent performance. Selection may depend on environmental exposure and existing connector standards in your application.

Q: Do both parts meet current regulatory requirements?

A: Yes. The L77HDBH44SOL2 is RoHS Compliant, while the 180-044-213R911 is ROHS3 Compliant. Both are REACH Unaffected and classified as EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What does "Board Lock" feature on the 180-044-213R911 provide?

A: The board lock feature mechanically secures the connector to the PCB, providing additional retention force. This is an optional feature not present on the standard L77HDBH44SOL2 configuration and may be advantageous in applications subject to vibration or mechanical stress.

Q: Are the 44-position contact patterns identical between both parts?

A: Yes. Both parts feature 44 positions arranged in 3 rows with Shell Size 3 (DB, B) High Density configuration, ensuring identical mating characteristics with standard D-Sub high density plugs and cable assemblies.
