Amphenol ICC 63453-348 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-348 is a 48-position receptacle connector from the Minitek® 2.00mm series, designed for board-to-board applications with through-hole solder termination. This connector features gold-plated mating contacts, tin-plated posts, and operates across -55°C to 125°C with a 2A current rating at 200V. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications in general purpose, industrial, and medical environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63453-348 is determined by strict alignment with the following core parameters: 48-position configuration, 0.079" (2.00mm) pitch mating, 2-row layout with 0.079" row spacing, through-hole solder mounting, push-pull fastening, and receptacle connector type with female socket contacts. All substitute parts must maintain these dimensional and functional specifications to ensure mechanical and electrical compatibility in board-to-board applications.

The three qualified substitutes are grouped as follows:

Direct Manufacturer Variant (63453-348LF): Identical electrical and mechanical specifications to the main part, differing only in product status (Active vs. Obsolete) and RoHS compliance status.

Cross-Manufacturer Substitutes (4-1734506-7, 833-13-048-10-002000): Functionally equivalent 48-position, 2.00mm pitch receptacle connectors from TE Connectivity and Mill-Max Manufacturing, maintaining core dimensional compatibility while introducing minor variations in contact finish specifications and operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

63453-348LF is the primary substitute for the obsolete 63453-348. Both parts are manufactured by Amphenol ICC within the Minitek® 2.00mm series and share identical electrical and mechanical specifications. The 63453-348LF is currently in active production status with higher inventory availability (836 pcs vs. 766 pcs). The key distinction is RoHS compliance: the 63453-348LF is RoHS Compliant while the original part is non-compliant, making it the preferred choice for applications subject to RoHS regulations.

4-1734506-7 (TE Connectivity AMPMODU series) is a qualified cross-manufacturer substitute maintaining full dimensional compatibility. This part operates within a narrower temperature range (-40°C to 105°C versus -55°C to 125°C) and does not specify a current rating. The voltage rating is 250VAC, exceeding the original 200V specification. This substitute is suitable for applications within the reduced temperature envelope and where higher voltage tolerance is acceptable.

833-13-048-10-002000 (Mill-Max Manufacturing series 833) maintains core dimensional specifications but introduces material and contact differences. The contact shape is circular rather than square, and the contact material is beryllium copper instead of phosphor bronze. The current rating is 3A, exceeding the original 2A specification. This part is RoHS non-compliant and carries MSL Not Applicable status. Selection of this substitute requires verification that the circular contact geometry and beryllium copper material are compatible with the mating connector design.

Frequently Asked Questions (FAQ)

Q: Can 63453-348LF be used as a direct replacement for 63453-348?

A: Yes. The 63453-348LF is manufactured by the same company (Amphenol ICC) within the same Minitek® 2.00mm series and maintains identical electrical and mechanical specifications. The primary difference is product status (Active vs. Obsolete) and RoHS compliance. For applications requiring RoHS compliance, 63453-348LF is the appropriate choice.

Q: What are the key compatibility requirements for substituting the 63453-348?

A: Any substitute must maintain the following specifications: 48-position receptacle configuration, 0.079" (2.00mm) mating pitch, 2-row layout with 0.079" row spacing, through-hole solder termination, push-pull fastening, and female socket contacts. Deviations in these parameters will result in mechanical or electrical incompatibility.

Q: Are there temperature limitations when using 4-1734506-7 as a substitute?

A: Yes. The 4-1734506-7 operates within -40°C to 105°C, which is narrower than the original 63453-348 range of -55°C to 125°C. This substitute is suitable only for applications that remain within the -40°C to 105°C envelope.

Q: What is the difference between the contact materials in the substitute parts?

A: The 63453-348 and 63453-348LF use phosphor bronze contacts, while 4-1734506-7 also uses phosphor bronze. The 833-13-048-10-002000 uses beryllium copper contacts. Contact material affects electrical conductivity, durability, and cost. Beryllium copper offers superior properties but requires compatibility verification with the mating connector design.

Q: Does the 833-13-048-10-002000 have a different contact geometry?

A: Yes. The 833-13-048-10-002000 features circular contacts, whereas the 63453-348 and other substitutes use square contacts. This geometric difference requires verification that the mating connector is designed to accept circular contact geometry.

Q: What packaging options are available for these substitutes?

A: The 63453-348LF is supplied in Tube packaging, 4-1734506-7 in Tray packaging, and 833-13-048-10-002000 in Bulk packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Are all substitutes RoHS compliant?

A: No. The 63453-348LF and 4-1734506-7 are RoHS compliant. The original 63453-348 and 833-13-048-10-002000 are RoHS non-compliant. For applications subject to RoHS regulations, use 63453-348LF or 4-1734506-7.
