TE Connectivity 3-1658043-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-1658043-2 is a 56-position differential pair array rectangular connector designed for surface mount applications. This female connector features a MICTOR SB series configuration with gold-plated contacts and is classified as an active product. The connector accommodates multiple mated stacking heights and includes integrated board guide and ground bus plane features, making it suitable for high-density interconnect applications requiring differential signal transmission.

Substitute parts are identified when components share identical electrical and mechanical specifications, allowing direct replacement without circuit redesign or board layout modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3-1658043-2 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following critical specifications:

• Connector type classification as differential pair array, female configuration
• Exact position count of 56 positions
• Identical pitch of 0.031" (0.80mm)
• Two-row configuration
• Surface mount mounting technology
• Gold contact finish with flash thickness
• Presence of board guide and ground bus plane features
• Matching height above board of 0.128" (3.25mm)
• Identical mated stacking height options
• MICTOR SB series designation
• Moisture sensitivity level 1 rating

The substitute part 1-1658043-2 meets all these parameters and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 3-1658043-2 and 1-1658043-2 are active products from TE Connectivity and share identical electrical and mechanical specifications. The primary distinction between these parts is the RoHS compliance status.

The 3-1658043-2 carries a RoHS status designation of "Not applicable," while the 1-1658043-2 is ROHS3 compliant. For applications subject to RoHS3 regulatory requirements, the 1-1658043-2 is the appropriate selection. For applications without RoHS compliance mandates, either part is functionally equivalent.

Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, indicating identical export and tariff classifications. The moisture sensitivity level of 1 (Unlimited) for both parts indicates no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 1-1658043-2 be used as a direct replacement for the 3-1658043-2?

A: Yes. The 1-1658043-2 is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is possible without circuit redesign or board layout modification.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 1-1658043-2 is ROHS3 compliant, while the 3-1658043-2 is not applicable for RoHS. All other specifications, including connector type, position count, pitch, mounting type, contact finish, and stacking heights, are identical.

Q: Are the mated stacking heights the same for both parts?

A: Yes. Both the 3-1658043-2 and 1-1658043-2 support identical mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, 22mm, 25mm, and 30mm.

Q: Does the gold contact finish differ between these parts?

A: No. Both parts feature gold contact finish with flash thickness, providing identical electrical and corrosion resistance properties.

Q: Which part should be selected for RoHS-regulated applications?

A: The 1-1658043-2 should be selected for applications requiring ROHS3 compliance. This part carries explicit ROHS3 compliant certification.

Q: Are there any differences in board guide or ground bus features?

A: No. Both parts include identical board guide and ground bus (plane) features for mechanical stability and signal integrity.

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

A: Both parts have a moisture sensitivity level of 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly processes.
