TE Connectivity 104652-2 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104652-2 is a 20-position receptacle connector from the AMPMODU 50/50 Grid series, designed for surface mount applications with 0.050" (1.27mm) pitch mating. This connector features female socket contacts with gold mating finish and push-pull fastening, suitable for board-to-board or cable interconnections. The part is currently active in production with 938 pieces available in inventory. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors within the TE Connectivity AMPMODU 50/50 Grid series is determined by strict equivalence of the following parameters:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (20)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows at 0.050" spacing)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Mating contact finish (Gold)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-65°C to 105°C)

The substitute part 5-104652-2 maintains full equivalence across all critical parameters. Variations in post contact finish (Tin-Lead versus Tin) and regulatory compliance status do not affect mechanical or electrical interchangeability within the connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both the 104652-2 and 5-104652-2 are active production parts from TE Connectivity within the AMPMODU 50/50 Grid series. Selection between these parts is based on regulatory and compliance requirements:

104652-2 Selection Criteria:

• Applications where Tin-Lead post finish is specified or required
• Designs where REACH Affected status is acceptable
• Environments where RoHS compliance is not a requirement

5-104652-2 Selection Criteria:

• Applications requiring ROHS3 compliance
• Designs requiring lead-free post finish (Tin)
• Environments where REACH compliance status must be defined
• New designs where regulatory compliance is mandatory

Both parts provide identical mechanical and electrical interface characteristics. The connector interface, mating pitch, contact geometry, and operating temperature range are fully equivalent. Selection should be driven by end-application regulatory requirements and manufacturing process specifications.

Frequently Asked Questions (FAQ)

Q: Are the 104652-2 and 5-104652-2 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 20-position configuration, 0.050" (1.27mm) mating pitch, 2-row layout, surface mount termination, and push-pull fastening. Mated stacking heights are identical at 6.35mm, 8.13mm, and 9.91mm.

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

A: The primary differences are post contact finish (Tin-Lead versus Tin) and regulatory compliance status. The 5-104652-2 is ROHS3 compliant with Tin post finish, while the 104652-2 uses Tin-Lead post finish and is not RoHS applicable. Mating contact finish (Gold) is identical for both parts.

Q: Can I use 5-104652-2 as a direct replacement for 104652-2?

A: Direct replacement is possible when the application permits lead-free (Tin) post finish and ROHS3 compliance. If the original design specifies Tin-Lead post finish or does not require RoHS compliance, verify compatibility with design documentation before substitution.

Q: Are the electrical characteristics identical?

A: Yes. Both connectors provide identical mating contact finish (Gold at 30.0µin thickness), contact material (Copper Alloy), and operating temperature range (-65°C to 105°C). No electrical performance difference exists between the two parts.

Q: What is the significance of the different REACH statuses?

A: The 104652-2 is listed as REACH Affected, indicating it contains substances of concern. The 5-104652-2 has Vendor Undefined REACH status. For applications subject to REACH regulations, the 5-104652-2 may require additional compliance verification from the vendor.

Q: Do both parts have the same inventory availability?

A: No. The 104652-2 has 938 pieces in stock, while the 5-104652-2 has significantly higher availability at 270,465 pieces. For high-volume production, the 5-104652-2 may offer better lead time and supply chain stability.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These connectors have unlimited shelf life and do not require special moisture control during storage or handling.

Q: Are both parts suitable for board-to-board and cable applications?

A: Yes. Both connectors are classified as Board to Board or Cable style, providing flexibility for various interconnection configurations within the same mechanical and electrical specifications.
