Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 394452 is determined by strict alignment of the following critical parameters:

Position and Pitch Configuration: The substitute part must maintain 80 total positions arranged in an 8-row by 10-column matrix with a 0.098" (2.50mm) pitch to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Connector Type and Termination: Both the main part and substitute must be header connectors with male pins using press-fit termination for through-hole mounting applications.

Contact Material and Finish: Gold-plated contacts are required to maintain electrical performance and corrosion resistance characteristics.

Compliance and Environmental Ratings: The substitute must meet UL94 V-0 flammability requirements, maintain ROHS3 compliance, and support the specified moisture sensitivity level classification.

The TE Connectivity AMP Connectors part number 2170330-1 satisfies all these critical substitution criteria while offering the advantage of active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2170330-1 is the designated substitute for the obsolete TE Connectivity Erni 394452. This substitution is supported by complete alignment of all critical mechanical and electrical parameters, including position count, pitch spacing, mounting method, and termination type.

The substitute part offers the following advantages:

Active Product Status: The 2170330-1 maintains active production status, ensuring long-term component availability and supply chain continuity compared to the obsolete 394452.

Regulatory Compliance: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for equivalent applications.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage and handling.

Documented Electrical Specifications: The substitute part provides specified current rating (0.700A) and voltage rating (250V) parameters, enabling precise circuit design validation.

Temperature Operating Range: While the substitute operates within a slightly narrower temperature range (-65°C ~ 105°C versus -55°C ~ 125°C), this range accommodates the majority of industrial and commercial applications. Applications requiring the full -55°C ~ 125°C range must be evaluated against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2170330-1 be used as a direct replacement for the 394452 in existing designs?

A: Yes. Both parts share identical position count (80), pitch spacing (0.098" / 2.50mm), row and column configuration (8x10), mounting type (through-hole), and termination method (press-fit). The mechanical and electrical interfaces are compatible.

Q: What is the difference in operating temperature range between these parts?

A: The 394452 operates from -55°C to 125°C, while the 2170330-1 operates from -65°C to 105°C. The substitute provides lower temperature capability but a reduced upper temperature limit. Applications operating above 105°C require design review.

Q: Are there packaging differences between these parts?

A: Yes. The 394452 is supplied in tray packaging, while the 2170330-1 is supplied in tube packaging. This affects handling, storage, and automated assembly processes but does not impact component functionality.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 394452 and 2170330-1 are ROHS3 compliant and carry UL94 V-0 flammability certification. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What electrical specifications are provided for the substitute part?

A: The 2170330-1 is rated for 0.700A per contact and 250V maximum voltage. The original 394452 does not specify these parameters in available documentation.

Q: Is the contact finish thickness specified for both parts?

A: The 394452 does not specify contact finish thickness. The 2170330-1 specifies 30.0µin (0.76µm) gold plating thickness, providing documented contact durability characteristics.

Q: What is the series designation for the substitute part?

A: The 2170330-1 belongs to the Z-PACK HM-Zd series from TE Connectivity AMP Connectors.
