TE Connectivity 145166-8 PCI Card Edge Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 145166-8 is a 184-position female PCI card edge connector designed for PCI 5V 64-bit applications. This connector features a 0.050" (1.27mm) pitch, dual read-out configuration, and gold-plated phosphor bronze contacts suitable for through-hole solder termination with staggered contact arrangement. The connector includes board guide features and accommodates 0.062" (1.57mm) card thickness.

The 145166-8 maintains active product status and is currently in stock. Identifying equivalent and substitute parts is necessary for procurement flexibility, supply chain continuity, and compliance with evolving regulatory requirements such as RoHS standards.

Substitute Part Grouping Explanation

Substitution of the 145166-8 connector is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5145166-8 qualifies as a direct equivalent based on the following criteria:

Critical Substitution Parameters:

• Identical 184-position configuration
• Matching 0.050" (1.27mm) pitch specification
• Identical PCI 5V 64-bit card type designation
• Matching female gender and dual read-out configuration
• Identical 0.062" (1.57mm) card thickness accommodation
• Identical phosphor bronze contact material with gold finish
• Matching through-hole solder termination with staggered arrangement
• Identical board guide feature set
• Identical thermoplastic insulation material

The 5145166-8 differs from the 145166-8 only in packaging format (bulk versus standard) and RoHS compliance status. These differences do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 145166-8 and 5145166-8 are electrically and mechanically equivalent PCI card edge connectors suitable for identical applications. Selection between these parts should be based on the following criteria:

145166-8 Selection Criteria:

• Applications where RoHS non-compliance is acceptable or required
• Standard packaging requirements
• Existing inventory or supply chain established with this part number

5145166-8 Selection Criteria:

• Applications requiring ROHS3 compliance
• Bulk packaging requirements for high-volume procurement
• New designs or systems with regulatory compliance mandates
• Supply chain preference for RoHS-compliant components

Both parts maintain active product status and are available in stock. The choice between these equivalents should be driven by regulatory requirements, packaging specifications, and procurement logistics rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the 145166-8 and 5145166-8 electrically interchangeable?

A: Yes. Both connectors feature identical electrical specifications including 184-position configuration, 0.050" pitch, PCI 5V 64-bit designation, phosphor bronze contacts with gold finish, and solder termination. They perform identically in circuit applications.

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

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 145166-8 is RoHS non-compliant, while the 5145166-8 is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Can I substitute the 145166-8 with the 5145166-8 in an existing design?

A: Yes, the 5145166-8 is a direct mechanical and electrical substitute for the 145166-8. No design modifications are required. However, verify that your application or regulatory environment permits or requires ROHS3 compliance before making the substitution.

Q: Does packaging format affect connector performance?

A: No. Bulk and standard packaging formats do not affect connector electrical performance or mechanical compatibility. Packaging differences relate only to procurement quantity and handling logistics.

Q: Are both parts currently available?

A: Yes. The 145166-8 has 1156 pieces in stock, and the 5145166-8 has 1456 pieces in stock as new original inventory.

Q: What card thickness does this connector accommodate?

A: Both connectors accommodate 0.062" (1.57mm) card thickness, which is the standard PCI specification.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
