TE Connectivity 2102061-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2102061-2 is a 114-position receptacle connector from the Mezalok VITA 61 series, designed for board-to-board surface mount applications. This connector features a 0.050" (1.27mm) pitch with 6 rows and gold-plated mating contacts rated for 250VAC operation across a temperature range of -55°C to 125°C. The component is currently active in production with 35,597 units in stock inventory.

Substitute parts are identified when design requirements necessitate alternative connector configurations, inventory constraints occur, or when specific compliance certifications become critical to application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2102061-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (114)
• Pitch specification (0.050" / 1.27mm)
• Number of rows (6)
• Row spacing (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Contact finish on mating surface (Gold)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Series designation (Mezalok, VITA 61)

The substitute part 2102061-1 maintains equivalence across all mandatory parameters. Differences in post contact finish material (Tin-Lead versus Tin) and RoHS compliance status do not affect mating interface compatibility or electrical performance in the connector interface.

Engineering Selection Recommendations

2102061-2 Selection Criteria: The 2102061-2 is the primary selection for applications requiring ROHS3 compliance. This part maintains full active production status with substantial inventory availability (35,597 units). The tin post contact finish aligns with lead-free soldering processes and modern manufacturing standards.

2102061-1 Selection Criteria: The 2102061-1 serves as a functional substitute where RoHS compliance is not a design requirement. This part is suitable for legacy systems, military applications with specific procurement specifications, or situations where tin-lead post finishes are explicitly required. Inventory availability is limited (1,990 units) relative to the main part.

Compliance Considerations: Selection between these parts must account for end-application regulatory requirements. Applications subject to RoHS directives, WEEE regulations, or customer-imposed environmental compliance mandates require the 2102061-2. Applications without such constraints may utilize either part based on availability and procurement specifications.

Both parts maintain identical mating interface specifications, electrical ratings, and mechanical dimensions, ensuring direct substitution capability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can 2102061-1 be used as a direct replacement for 2102061-2 in production assemblies?

A: The 2102061-1 provides functional equivalence at the connector mating interface. Both parts share identical pin counts, pitch specifications, contact materials, and electrical ratings. The primary distinction is RoHS compliance status and post contact finish material. Substitution is permissible only when application requirements do not mandate ROHS3 compliance.

Q: What is the difference between the tin and tin-lead post finishes?

A: The 2102061-2 features tin post contact finish, compatible with lead-free soldering processes. The 2102061-1 features tin-lead post contact finish, compatible with traditional lead-containing solder processes. This difference affects PCB assembly methodology but does not impact the mating interface performance or electrical characteristics.

Q: Are these connectors interchangeable with other Mezalok VITA 61 series components?

A: Interchangeability is limited to parts with identical position counts, pitch specifications, and row configurations. The 114-position, 0.050" pitch, 6-row configuration is specific to these two part numbers. Other Mezalok VITA 61 variants with different position counts or pitch specifications are not interchangeable.

Q: What inventory considerations should guide part selection?

A: The 2102061-2 maintains significantly higher inventory levels (35,597 units) compared to 2102061-1 (1,990 units). For high-volume production requirements, the 2102061-2 offers superior supply chain reliability. The 2102061-1 should be reserved for applications where RoHS compliance is not applicable and inventory availability of the primary part is constrained.

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

A: Both parts carry Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life without moisture control requirements. Standard electronic component storage practices apply.

Q: What is the mated stacking height specification?

A: Both the 2102061-2 and 2102061-1 achieve a mated stacking height of 10mm when fully engaged with compatible plug connectors. This specification is critical for PCB layout and enclosure design calculations.
