Amphenol ICC 77313-183-20 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-183-20 is a rectangular connector header with vertical orientation, 20 positions, and 2.54mm pitch spacing. This through-hole component is designed for board-to-board or cable connections with solder termination and push-pull fastening. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77313-183-20 is determined by the following critical parameters: connector type (header), contact type (male pin or solder cup), number of positions (20), number of rows (2), pitch spacing (2.54mm), mounting type (through hole), and termination method (solder). The substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications requiring a 20-position, dual-row header connector with 2.54mm pitch.

The 77313-183-20LF is a direct equivalent from the same manufacturer series (BERGSTIK®) with identical mechanical and electrical specifications. The TD-110-G-B from Samtec Inc. provides an alternative solution with the same pitch, position count, and row configuration, though with a different contact type (solder cup versus male pin).

Parameter Comparison

Engineering Selection Recommendations

The 77313-183-20LF is the primary substitute for the obsolete 77313-183-20. Both parts are from the Amphenol ICC BERGSTIK® series and share identical mechanical and electrical specifications. The 77313-183-20LF offers the advantage of active product status and RoHS compliance, making it suitable for new designs and applications with environmental or regulatory requirements.

The TD-110-G-B from Samtec Inc. serves as an alternative when the specific contact type (solder cup) is acceptable for the application. This part maintains the same pitch, position count, and row configuration, with active product status and ROHS3 compliance. Selection between the male pin configuration (77313-183-20LF) and solder cup configuration (TD-110-G-B) depends on the mating interface requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the 77313-183-20LF be used as a direct replacement for the 77313-183-20?

A: Yes. The 77313-183-20LF maintains identical mechanical and electrical specifications, including pitch (2.54mm), position count (20), row configuration (2 rows), contact type (male pin), and termination method (solder). The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the key difference between the 77313-183-20LF and TD-110-G-B?

A: The primary difference is contact type. The 77313-183-20LF features male pins, while the TD-110-G-B uses solder cups. Both maintain the same pitch (2.54mm), position count (20), and row spacing (2.54mm). Selection depends on whether the mating interface requires male pin or solder cup termination.

Q: Are there packaging differences between these parts?

A: Yes. The 77313-183-20LF is supplied in bag packaging, while the TD-110-G-B is supplied in bulk packaging. These packaging differences do not affect electrical or mechanical compatibility.

Q: Which substitute part is recommended for new designs?

A: The 77313-183-20LF is recommended for new designs requiring male pin contact configuration. It offers active product status, RoHS compliance, and specified operating temperature range (-65°C ~ 130°C) and current rating (3A per contact).

Q: Can the TD-110-G-B be used if the application requires male pin contacts?

A: No. The TD-110-G-B features solder cup contacts, not male pins. If male pin contacts are required, the 77313-183-20LF is the appropriate substitute.
