Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 120523-1 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle with outer shroud contacts
• Position Count: 64 positions
• Pitch Specification: 0.039" (1.00mm)
• Row Configuration: 2 rows
• Mounting Technology: Surface mount
• Contact Material and Finish: Gold plating at 30.0µin (0.76µm) thickness
• Mechanical Dimensions: Mated stacking height of 13mm and height above board of 0.330" (8.38mm)
• Series Classification: Free Height (FH) IEEE 1386, PMC
• Functional Features: Board guide inclusion

The substitute part 5146895-1 meets all these critical parameters and is therefore classified as a parametric equivalent. The primary distinction between the main part and its substitute relates to packaging format and regulatory compliance status, not electrical or mechanical function.

Engineering Selection Recommendations

Primary Selection: TE Connectivity 120523-1

The 120523-1 is the baseline part number with established Active product status and substantial inventory availability (392,005 pieces). This part is suitable for applications where RoHS non-compliance is acceptable or where legacy system compatibility is required.

Substitute Selection: TE Connectivity 5146895-1

The 5146895-1 is a parametric equivalent offering identical electrical and mechanical specifications. This part is designated as RoHS Compliant, making it the appropriate choice for applications subject to RoHS regulatory requirements or for new designs requiring environmental compliance certification. The part is supplied in Cut Tape (CT) packaging format and maintains Active product status.

Selection Criteria

• Select 120523-1 when RoHS non-compliance is acceptable and standard packaging is required
• Select 5146895-1 when RoHS compliance is mandatory or when Cut Tape packaging format is specified
• Both parts are functionally interchangeable from electrical and mechanical perspectives
• Both parts maintain identical dimensional specifications, contact characteristics, and series classification

Frequently Asked Questions (FAQ)

Q: Are the 120523-1 and 5146895-1 electrically interchangeable?

A: Yes. Both parts are 64-position rectangular connectors with identical pitch (0.039"/1.00mm), contact finish (gold at 30.0µin thickness), and mounting specifications. They are electrically equivalent and will function identically in circuit applications.

Q: What is the primary difference between these two parts?

A: The primary differences are RoHS compliance status and packaging format. The 120523-1 is RoHS non-compliant with unspecified packaging, while the 5146895-1 is RoHS Compliant and supplied in Cut Tape (CT) packaging. All electrical and mechanical parameters are identical.

Q: Can I use 5146895-1 as a direct replacement for 120523-1 in existing designs?

A: Yes. The 5146895-1 meets all electrical and mechanical specifications of the 120523-1. The substitution is valid from a functional standpoint. Verify that RoHS compliance and Cut Tape packaging are compatible with your procurement and assembly processes.

Q: What does the Cut Tape (CT) packaging format mean?

A: Cut Tape packaging supplies components on a continuous carrier tape that is cut to specific lengths for shipment. This format is commonly used for automated assembly processes and offers different handling and storage characteristics compared to bulk or reel packaging.

Q: Are both parts still in active production?

A: Yes. Both the 120523-1 and 5146895-1 maintain Active product status, indicating ongoing manufacturing and availability.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures.

Q: Do these connectors require any special handling or storage conditions?

A: With an MSL rating of 1 (Unlimited), no special moisture control or storage conditions are required. Standard component storage practices are sufficient.

Q: What is the significance of the IEEE 1386 and PMC series designation?

A: The Free Height (FH) IEEE 1386 PMC series classification indicates the connector conforms to IEEE 1386 standards for PMC (PCI Mezzanine Card) applications. This series designation ensures compatibility with systems designed to these specifications.
