TE Connectivity 106774-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 106774-1 is a 125 Position Receptacle connector with female sockets, 0.079" (2.00mm) pitch, designed for backplane applications. This connector features press-fit termination, through-hole mounting, and gold-plated contacts rated for 1.5 A at 500Vrms across an operating temperature range of -55°C to 125°C. The part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution for the 106774-1 receptacle connector is determined by the following critical parameters: connector type (receptacle vs. header), number of positions, pitch (2.00mm), number of rows, mounting type (through hole), termination method (press-fit), current rating (1.5 A minimum), voltage rating (500Vrms minimum), operating temperature range (-55°C to 125°C), and connector style (B 25).

The direct equivalent substitute is 5106774-1, which maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the primary replacement for the obsolete 106774-1.

Header connectors (male pins) from the Amphenol ICC Millipacs® series provide complementary mating components. These headers share the same pitch, number of positions, rows, mounting type, termination method, current rating, operating temperature range, and connector style. However, header connectors feature higher voltage ratings (750Vrms) and different contact finish specifications. Headers with 125 positions (HM2P08PA5110AALF, HM2P08PA5111AALF, HM2P08PD5110N9LF, HM2P08PDE120N9L1LF) directly correspond to the 106774-1 position count. Headers with 150 or 175 positions include additional ground pins and represent extended configurations not directly equivalent to the base 125-position receptacle.

Engineering Selection Recommendations

Primary Substitute: 5106774-1

The 5106774-1 is the direct equivalent replacement for the obsolete 106774-1. This part maintains identical electrical and mechanical specifications, including 125 positions, 2.00mm pitch, 5 rows, press-fit termination, 1.5 A current rating, and 500Vrms voltage rating. The 5106774-1 offers active product status and RoHS compliance, addressing regulatory requirements for new designs. Packaging is supplied in tube format. This part is the recommended primary selection for direct substitution.

Complementary Header Options: Amphenol ICC Millipacs® Series

Header connectors HM2P08PA5110AALF, HM2P08PA5111AALF, HM2P08PD5110N9LF, and HM2P08PDE120N9L1LF provide mating male pin components for 125-position backplane applications. These headers share identical position count, pitch, row configuration, mounting type, termination method, current rating, and operating temperature range. All Amphenol ICC options feature RoHS compliance and active product status. Voltage rating is elevated to 750Vrms, providing additional margin. Contact finish specifications vary by part number (gold plating thickness or flash finish). These headers are suitable for new backplane connector pair designs requiring complementary receptacle and header components.

Extended Position Configurations

Headers HM2P08PD5115N9LF (150 positions with 25 ground pins), HM2P08PDE121E9LF, HM2P08PDE121L9LLF, HM2P08PDE121N9L1LF, and HM2P08PDE121N9LF (175 positions with 50 ground pins) represent extended configurations with additional ground pins. These parts are not direct equivalents to the 125-position 106774-1 and are applicable only when expanded position counts or dedicated ground pin distribution is required.

Frequently Asked Questions (FAQ)

Q: Can the 5106774-1 directly replace the obsolete 106774-1?

A: Yes. The 5106774-1 is the direct equivalent substitute. It maintains identical electrical specifications (1.5 A, 500Vrms), mechanical configuration (125 positions, 2.00mm pitch, 5 rows, through-hole press-fit), and connector style (B 25). The primary differences are active product status and RoHS compliance. Packaging is supplied in tube format rather than bulk.

Q: What is the relationship between the 106774-1 receptacle and Amphenol ICC header connectors?

A: The Amphenol ICC Millipacs® headers (HM2P08 series) are complementary mating components designed for the same backplane connector interface. They share identical pitch (2.00mm), position count (125 for base models), row configuration (5), mounting type (through-hole), termination method (press-fit), current rating (1.5 A), and operating temperature range (-55°C to 125°C). Headers feature higher voltage rating (750Vrms) and are used as the male pin component in receptacle-header connector pairs.

Q: Are the 150-position and 175-position headers equivalent to the 106774-1?

A: No. The 150-position (HM2P08PD5115N9LF) and 175-position headers (HM2P08PDE121E9LF, HM2P08PDE121L9LLF, HM2P08PDE121N9L1LF, HM2P08PDE121N9LF) include additional ground pins beyond the base 125 signal positions. These extended configurations are not direct equivalents and are applicable only when expanded position counts or dedicated ground pin distribution is required.

Q: What are the packaging differences among substitute parts?

A: The 5106774-1 is supplied in tube packaging. Amphenol ICC Millipacs® headers are supplied in tray packaging. Packaging format affects handling, storage, and automated assembly processes. Verify packaging compatibility with procurement and assembly requirements before selection.

Q: Are all substitute parts RoHS compliant?

A: The 5106774-1 and all Amphenol ICC Millipacs® header options listed are RoHS compliant. The original 106774-1 is RoHS non-compliant. RoHS compliance is required for new designs and applications subject to regulatory requirements.

Q: What is the voltage rating difference between the 106774-1 and Amphenol ICC headers?

A: The 106774-1 receptacle is rated for 500Vrms. Amphenol ICC Millipacs® headers are rated for 750Vrms. The higher voltage rating of the headers provides additional electrical margin and does not prevent their use in 500Vrms applications.

Q: Can contact finish specifications vary among substitute parts?

A: Yes. Contact finish thickness varies by part number. The 106774-1 specifies 30.0µin (0.76µm) gold plating. Amphenol ICC headers specify either flash finish, 30.0µin (0.76µm), 39.4µin (1.00µm), or 51.2µin (1.30µm) depending on the specific part number. All finishes are gold-based and suitable for the specified electrical and environmental conditions.
