Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5146888-2 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Connector Type and Position Count: All substitutes maintain 84-position plug configuration with center strip contacts
• Pitch and Row Configuration: 0.039" (1.00mm) pitch with 2-row arrangement is consistent across all parts
• Mounting Technology: Surface mount designation is maintained for all equivalents
• Contact Specifications: Gold finish at 30.0µin (0.76µm) thickness is uniform
• Physical Dimensions: Height above board (0.329" / 8.35mm) and mated stacking heights (10mm, 12mm, 13mm, 15mm) are identical
• Series Compliance: All parts conform to Free Height (FH) IEEE 1386 and PMC standards
• Environmental Ratings: MSL 1 (Unlimited) and RoHS compliance are maintained

Substitute parts differ only in packaging format (Tape & Reel versus Cut Tape) and base product number designation, which do not affect electrical or mechanical compatibility in the application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5146888-2, 2-5120527-2, and 5120527-2—are functionally equivalent for applications requiring 84-position rectangular connector plugs with the specified electrical and mechanical characteristics. Selection between these parts is determined by packaging and compliance requirements rather than performance differences.

5146888-2 (Tape & Reel packaging, RoHS Compliant) is suitable for standard production environments where standard RoHS compliance is required and tape-and-reel packaging supports automated assembly processes.

2-5120527-2 (Tape & Reel packaging, ROHS3 Compliant) provides enhanced environmental compliance through ROHS3 certification and is appropriate for applications with stricter regulatory requirements while maintaining tape-and-reel packaging benefits.

5120527-2 (Cut Tape packaging, RoHS Compliant) is appropriate for lower-volume applications, prototype development, or situations where individual component handling is preferred over continuous reel formats. Cut tape packaging eliminates reel waste in small-quantity scenarios.

All parts maintain active production status and are available in adequate inventory quantities. Selection should be based on packaging format requirements and specific regulatory compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can 5120527-2 be used as a direct replacement for 5146888-2 in production assembly?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The primary difference is packaging format: 5146888-2 is supplied in Tape & Reel (TR) format while 5120527-2 is supplied in Cut Tape (CT) format. Tape & Reel packaging is optimized for high-speed automated assembly, while Cut Tape is suitable for lower-volume or manual assembly processes. The connector itself functions identically in the application.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents a more recent or enhanced compliance standard. Part 2-5120527-2 carries ROHS3 certification, while 5146888-2 and 5120527-2 carry standard RoHS certification. Selection between these should be based on specific regulatory requirements for the end application or geographic market.

Q: Are the mated stacking heights identical across all substitute parts?

A: Yes. All three parts support identical mated stacking heights of 10mm, 12mm, 13mm, and 15mm. This ensures mechanical compatibility with mating receptacles and system-level integration requirements.

Q: Does packaging format affect the connector's electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape) affects only the delivery and handling method, not the electrical or mechanical performance of the connector itself. The connector specifications remain identical regardless of packaging.

Q: What is the significance of the 0.039" (1.00mm) pitch specification?

A: Pitch refers to the center-to-center distance between adjacent contact positions. The 0.039" (1.00mm) pitch is a critical parameter that determines physical compatibility with mating connectors and PCB layout requirements. All substitute parts maintain this identical pitch, ensuring interchangeability.

Q: Are all substitute parts currently in active production?

A: Yes. All three parts—5146888-2, 2-5120527-2, and 5120527-2—maintain active product status with TE Connectivity, indicating ongoing manufacturing and availability.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the lowest moisture sensitivity classification. These connectors do not require special moisture-controlled storage conditions and have unlimited shelf life under standard environmental conditions, simplifying inventory management and logistics.
