TE Connectivity AMP Connectors 102161-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 102161-4 is a rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 20-position connector operates at 0.100" (2.54mm) pitch and supports board-to-cable/wire interconnections with a 1A per contact current rating at 250VAC. The connector features push-pull fastening, gold or gold-palladium mating contact finish, and operates across a temperature range of -65°C to 105°C. As an active product with RoHS non-compliant status, alternative equivalent parts may be required for applications demanding RoHS3 compliance or specific regulatory requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 102161-4 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin
• Number of Positions: 20
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Current Rating: 1A per Contact
• Voltage Rating: 250VAC

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Number of Rows: 2

Environmental & Compliance Parameters:

• Operating Temperature: -65°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Connector Series: AMP-Latch

The substitute part 5102161-4 maintains full equivalence across all electrical and mechanical parameters. The primary distinction between the main part and substitute relates to RoHS compliance status and post-contact finish composition, which do not affect functional interchangeability in applications where these specifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Regulated Environments): The TE Connectivity 102161-4 is suitable for applications where RoHS compliance is not a requirement. This part maintains active product status and full operational compatibility across all electrical and mechanical parameters.

For RoHS3 Compliant Applications: The substitute part 5102161-4 is required for applications demanding ROHS3 compliance. This part is functionally equivalent to the main part across all critical electrical and mechanical parameters while meeting enhanced regulatory requirements. Both parts are active products from TE Connectivity AMP Connectors and maintain identical connector specifications, contact ratings, and operating characteristics.

Contact Finish Consideration: The primary technical difference between the two parts is the post-contact finish composition. The main part 102161-4 features Tin-Lead finish on the post contacts, while the substitute 5102161-4 features Tin finish. Both maintain identical contact finish thickness (100.0µin / 2.54µm) and mating contact finish specifications (Gold or Gold-Palladium at 15.0µin / 0.38µm). This difference reflects the RoHS3 compliance requirement of the substitute part and does not affect functional interchangeability in standard applications.

Inventory Availability: Both parts are available in bulk packaging with substantial inventory levels (102161-4: 952 Pcs; 5102161-4: 934 Pcs).

Frequently Asked Questions (FAQ)

Q: Are the 102161-4 and 5102161-4 connectors mechanically interchangeable?

A: Yes. Both connectors are identical in mechanical design, featuring 20-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, and push-pull fastening. They are direct mechanical substitutes.

Q: What is the primary difference between these two connector models?

A: The primary difference is RoHS compliance status. The 102161-4 is RoHS non-compliant, while the 5102161-4 is ROHS3 compliant. Additionally, the post-contact finish differs: 102161-4 uses Tin-Lead, while 5102161-4 uses Tin. Both maintain identical mating contact finish specifications and electrical performance.

Q: Can I use the 5102161-4 as a direct replacement for the 102161-4 in existing designs?

A: Yes, the 5102161-4 is a direct functional equivalent. All electrical parameters (1A per contact, 250VAC rating), mechanical specifications (20 positions, 2.54mm pitch, right-angle mounting), and environmental ratings (-65°C to 105°C, UL94 V-0) are identical. The substitute part is suitable for applications where the original part was specified.

Q: Which part should I select for new designs?

A: For new designs, select based on regulatory requirements. If RoHS3 compliance is mandated, use 5102161-4. If RoHS compliance is not required, either part is acceptable. Both are active products with equivalent availability and performance characteristics.

Q: Are there any compatibility issues with mating connectors?

A: No. Both the 102161-4 and 5102161-4 are header connectors with identical contact type (male pin), pitch (0.100" / 2.54mm), and row spacing (0.100" / 2.54mm). They are compatible with the same mating receptacle connectors.

Q: What is the current and voltage rating for these connectors?

A: Both connectors are rated for 1A per contact and 250VAC maximum voltage. These ratings apply to all 20 positions in the connector.

Q: What is the operating temperature range?

A: Both connectors operate across -65°C to 105°C, providing performance across industrial and commercial temperature ranges.

Q: Are these connectors suitable for high-reliability applications?

A: Both connectors feature UL94 V-0 material flammability rating and push-pull fastening for secure connections. The gold or gold-palladium mating contact finish provides corrosion resistance. Suitability for specific high-reliability applications depends on additional system-level requirements not specified in the connector parameters.
