Amphenol ICC 63453-120 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-120 is a 20-position receptacle connector with 0.079" (2.00mm) pitch, designed for board-to-board applications in general purpose, industrial, and medical environments. This connector features through-hole solder termination, push-pull fastening, and gold-plated mating contacts rated for 2A at 200V. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (20), mating pitch (0.079"/2.00mm), number of rows (2), mounting type (through hole), termination method (solder), and fastening type (push-pull). All substitute parts listed maintain these core electrical and mechanical specifications.

The primary substitute is the Amphenol ICC 63453-120LF, which is the lead-free variant of the main part with identical electrical and mechanical characteristics but improved RoHS compliance status. Secondary substitutes from Molex, TE Connectivity, Mill-Max, Harwin, and Samtec meet the core dimensional and functional requirements while offering variations in contact finish thickness, insulation material, and current/voltage ratings that may be acceptable depending on application requirements.

Engineering Selection Recommendations

The Amphenol ICC 63453-120LF is the direct replacement for the obsolete 63453-120. Both parts share identical electrical and mechanical specifications with matching current and voltage ratings (2A, 200V), operating temperature range (-55°C to 125°C), and UL94 V-0 flammability rating. The primary distinction is RoHS compliance status: the 63453-120LF is RoHS compliant while the original is non-compliant. This variant is recommended as the primary substitute for new designs and ongoing production.

For applications requiring higher current capacity, the Samtec MMS-110-01-F-DV and MMS-110-01-H-DV offer 3.9A per contact rating with identical pitch and row configuration. The MMS-110-01-H-DV provides gold post finish compared to tin on the -F variant.

The Harwin M22-7141042 maintains the 2A current rating and offers enhanced voltage rating (500VAC) with ROHS3 compliance and UL94 V-0 flammability rating. This part is suitable for industrial and telecommunications applications.

The TE Connectivity 3-1470209-3 and 8-1470209-3 provide 250VAC voltage rating with ROHS3 compliance. The 8-1470209-3 variant includes 30.0µin gold mating contact finish matching the original specification.

The Molex Milli-Grid series (0791077009, 0791077059, 0791077209) are ROHS3 compliant alternatives with reduced current rating (1A) and voltage rating (125V). These are suitable only for lower-power applications.

The Mill-Max 833-13-020-10-002000 offers 3A current capacity but is RoHS non-compliant and features circular contact geometry rather than square, requiring mechanical compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can the 63453-120LF directly replace the obsolete 63453-120?

A: Yes. The 63453-120LF is the lead-free variant with identical electrical and mechanical specifications. Both parts maintain 2A current rating, 200V voltage rating, -55°C to 125°C operating temperature, and UL94 V-0 flammability rating. The primary difference is improved RoHS compliance status on the LF variant.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution requires matching: 20-position receptacle configuration, 0.079" (2.00mm) mating pitch, 2-row layout with 0.079" row spacing, through-hole mounting, solder termination, push-pull fastening, and gold-plated mating contacts. Variations in contact finish thickness, post material, and insulation composition are acceptable provided core electrical ratings are maintained or exceeded.

Q: Are there current or voltage derating considerations when using substitute parts?

A: The Molex Milli-Grid series (0791077009, 0791077059, 0791077209) are rated for 1A at 125V, which is lower than the original 2A at 200V specification. These substitutes are suitable only for applications with reduced power requirements. The Samtec MMS series and Mill-Max 833 series exceed the original current rating and are suitable for higher-power applications.

Q: What packaging options are available for these substitutes?

A: The 63453-120LF is supplied in tube packaging. Molex Milli-Grid variants are supplied in tube. TE Connectivity AMPMODU parts are supplied in tray. Harwin M22-7141042 is supplied in tube. Samtec MMS variants are supplied in tube or unspecified packaging. Mill-Max 833 series is supplied in tube. Verify packaging requirements for your procurement and assembly processes.

Q: Do all substitute parts meet the same flammability and compliance standards?

A: The 63453-120LF, TE Connectivity 3-1470209-3 and 8-1470209-3, Harwin M22-7141042, and Mill-Max 833-13-020-10-002000 all carry UL94 V-0 flammability rating matching the original. The Molex Milli-Grid series and Samtec MMS variants do not specify flammability rating. All listed substitutes except the Mill-Max 833 series are RoHS compliant or ROHS3 compliant.

Q: What is the difference between contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The original 63453-120 specifies 30.0µin (0.76µm) gold mating finish. Substitutes with lower thickness (Molex at 15.0µin or 8.00µin, Samtec MMS-110-01-F-DV at 3.00µin) may have reduced contact life in high-cycle mating applications. Substitutes matching or exceeding the original thickness are preferred for demanding environments.

Q: Are there mechanical compatibility concerns with different insulation heights?

A: Insulation height variations are minor (0.173" to 0.179"). The original 63453-120 specifies 0.177" (4.50mm). Most substitutes fall within 0.175" to 0.179" range, which is acceptable for standard PCB mounting. Verify mechanical clearance in your specific application if tight spacing constraints exist.
