Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63453-346 is determined by strict alignment with the following critical parameters:

• Connector Type & Style: Receptacle, board-to-board configuration
• Position Count & Pitch: 46 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Contact Configuration: Female socket contacts with gold mating finish
• Electrical Ratings: Current and voltage ratings must meet or exceed 2A and 200V respectively
• Environmental Compliance: UL94 V-0 flammability rating and operating temperature range

The substitute parts listed below meet these core substitution criteria. Variations in contact finish thickness, post material composition, and insulation material formulation are within acceptable engineering tolerances for this connector category.

Parameter Comparison

Engineering Selection Recommendations

63453-346LF (Amphenol ICC): This is the direct successor to the 63453-346 within the same manufacturer's product line. It maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The 63453-346LF is the primary recommended substitute for new designs and ongoing production requiring the Minitek® 2.00mm series.

4-1734506-6 (TE Connectivity AMP Connectors): This AMPMODU series connector provides cross-manufacturer compatibility with identical pitch, row configuration, and position count. It meets the mechanical interface requirements and exceeds the voltage rating at 250VAC. The operating temperature range is reduced to -40°C ~ 105°C, which may limit suitability for applications requiring the full -55°C ~ 125°C range of the original part. RoHS compliance is confirmed.

833-13-046-10-002000 (Mill-Max Manufacturing Corp.): This 833 series connector maintains the core mechanical and electrical interface specifications. It offers a higher current rating of 3A and extended contact finish thickness on mating surfaces. The operating temperature range matches the original specification. RoHS compliance status is non-compliant, consistent with the original part. Contact geometry differs (circular vs. square), which may affect mating force and contact resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 63453-346LF be used as a direct replacement for the 63453-346?

A: Yes. The 63453-346LF is mechanically and electrically identical to the 63453-346, with the primary differences being active product status and RoHS compliance. No design modifications are required for substitution.

Q: What are the key differences between the TE Connectivity 4-1734506-6 and the original 63453-346?

A: The 4-1734506-6 maintains identical pitch, position count, and row spacing. The primary engineering differences are: reduced operating temperature range (-40°C ~ 105°C vs. -55°C ~ 125°C), increased voltage rating (250VAC vs. 200V), and different insulation material formulation (thermoplastic vs. PCT glass-filled). These differences may affect suitability for extreme temperature or high-reliability applications.

Q: Is the Mill-Max 833-13-046-10-002000 suitable for applications requiring the full -55°C ~ 125°C operating range?

A: Yes. The 833-13-046-10-002000 maintains the full -55°C ~ 125°C operating temperature range specified for the original 63453-346. However, the contact geometry is circular rather than square, which may introduce differences in contact resistance and mating force.

Q: What packaging options are available for these substitute parts?

A: The 63453-346LF is supplied in tube packaging. The 4-1734506-6 and 833-13-046-10-002000 are supplied in bulk packaging. Packaging selection should align with production volume and handling requirements.

Q: Are all substitute parts RoHS compliant?

A: The 63453-346LF and 4-1734506-6 are RoHS compliant. The 833-13-046-10-002000 is RoHS non-compliant, matching the compliance status of the original 63453-346.

Q: What is the impact of contact finish thickness variations on connector performance?

A: Contact finish thickness variations (10.0µin to 30.0µin) are within acceptable engineering tolerances for this connector category and do not affect electrical performance or mating compatibility. Thicker finishes may provide extended contact life in high-cycle applications.
