Amphenol ICC 63453-046 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-046 is a 46-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, push-pull fastening, and operates across -55°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Suitable alternatives must maintain the same pitch (0.079"), position count, mounting type, and electrical ratings to ensure direct compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Connector Type & Style: Must be receptacle, board-to-board configuration
• Position Count & Pitch: Must maintain 46 positions at 0.079" (2.00mm) mating pitch
• Mounting & Termination: Must be through-hole with solder termination
• Fastening Mechanism: Must feature push-pull fastening
• Contact Finish: Mating contacts must be gold-plated
• Electrical Performance: Current and voltage ratings must meet or exceed 2A and 200V respectively
• Environmental Rating: Operating temperature range and flammability rating (UL94 V-0) must be maintained

Three substitute parts meet these criteria with varying degrees of parameter alignment and product status differences.

Engineering Selection Recommendations

63453-046LF (Direct Amphenol ICC Equivalent)

This is the primary substitute for the obsolete 63453-046. It is manufactured by the same supplier (Amphenol ICC) within the identical Minitek® 2.00mm series and maintains all critical electrical and mechanical parameters. The only substantive difference is product status (active versus obsolete) and RoHS compliance. The 63453-046LF is RoHS compliant, making it suitable for applications with regulatory requirements. Packaging differs (tube versus bulk), but this does not affect functional compatibility. This part is the recommended first choice for direct replacement.

4-1734506-6 (TE Connectivity AMPMODU Alternative)

This TE Connectivity part maintains all core substitution criteria: 46 positions, 0.079" pitch, through-hole solder termination, and push-pull fastening. It is RoHS compliant and active in production. However, the operating temperature range is reduced (-40°C to 105°C versus -55°C to 125°C), which may limit suitability for applications requiring the full temperature envelope of the original part. Current rating is not specified. Voltage rating is specified as 250VAC, which exceeds the 200V requirement. This part is suitable for applications within the narrower temperature range.

833-13-046-10-002000 (Mill-Max Manufacturing Alternative)

This Mill-Max part maintains the full -55°C to 125°C operating temperature range and exceeds the current rating (3A versus 2A). However, it is RoHS non-compliant, matching the compliance status of the original obsolete part. Contact geometry differs (circular versus square), and contact material is beryllium copper rather than phosphor bronze. Insulation height is marginally different (0.179" versus 0.177"). This part is suitable for applications without RoHS requirements and where the enhanced current rating is beneficial.

Frequently Asked Questions (FAQ)

Q: Can 63453-046LF be used as a direct drop-in replacement for 63453-046?

A: Yes. The 63453-046LF is manufactured by Amphenol ICC in the same Minitek® 2.00mm series and maintains identical electrical and mechanical specifications. All critical parameters—position count, pitch, mounting type, termination, fastening, and contact finish—are identical. The primary difference is product status (active versus obsolete) and RoHS compliance. Packaging format differs (tube versus bulk), but this does not affect functional compatibility.

Q: What are the key differences between the three substitute options?

A: The 63453-046LF is the closest match, differing only in product status and RoHS compliance. The 4-1734506-6 (TE Connectivity) has a reduced operating temperature range (-40°C to 105°C) and unspecified current rating, but offers higher voltage rating (250VAC). The 833-13-046-10-002000 (Mill-Max) maintains the full temperature range and offers higher current capacity (3A), but uses different contact geometry and material, and is RoHS non-compliant.

Q: Which substitute should I select for a new design?

A: For new designs, the 63453-046LF is the recommended choice due to identical specifications, active product status, and RoHS compliance. If the application operates within -40°C to 105°C, the 4-1734506-6 is an acceptable alternative from a different manufacturer. The 833-13-046-10-002000 is suitable only if RoHS non-compliance is acceptable and the enhanced current rating is required.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All four parts share identical pitch (0.079"), position count (46), and row configuration (2 rows). Insulation height is consistent across all parts (0.177" to 0.179"), and all use push-pull fastening. The 833-13-046-10-002000 has slightly different contact geometry (circular versus square) and contact material (beryllium copper versus phosphor bronze), but these do not affect mechanical mating compatibility.

Q: What is the impact of RoHS compliance on part selection?

A: The original 63453-046 is RoHS non-compliant. The 63453-046LF and 4-1734506-6 are RoHS compliant, making them suitable for applications subject to RoHS regulations. The 833-13-046-10-002000 is RoHS non-compliant. If your application or market requires RoHS compliance, select either the 63453-046LF or 4-1734506-6.

Q: How do the electrical ratings compare across substitutes?

A: The 63453-046 and 63453-046LF both specify 2A at 200V. The 4-1734506-6 specifies 250VAC with unspecified current rating. The 833-13-046-10-002000 specifies 3A with unspecified voltage rating. For applications requiring both 2A and 200V specifications, the 63453-046LF is the only exact match among active parts.

Q: What packaging formats are available?

A: The 63453-046 and 4-1734506-6 are supplied in bulk packaging. The 63453-046LF is supplied in tube packaging. The 833-13-046-10-002000 is supplied in bulk packaging. Packaging format does not affect functional compatibility but may impact procurement and handling procedures.
