Amphenol ICC 63453-312 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-312 is a 12-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 gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63453-312 is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 12 positions in 2-row configuration
• Pitch Specification: 0.079" (2.00mm) mating pitch with 0.079" row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: Minimum 2A current rating and 200V voltage rating
• Contact Finish: Gold-plated mating surface
• Environmental Rating: Operating temperature range -55°C to 125°C

The Molex 0873801206 (Milli-Grid 87380 series) satisfies these core substitution criteria. Both connectors share identical position count, pitch, row spacing, mounting method, termination type, fastening mechanism, and mating contact finish specification. Mechanical and electrical compatibility is established through these matching parameters.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0873801206 is the manufacturer-recommended substitute for the obsolete Amphenol ICC 63453-312. Both connectors meet identical mechanical and electrical specifications for the 12-position, 2.00mm pitch board-to-board receptacle application.

Product Status Consideration: The 63453-312 is obsolete with no ongoing manufacturing. The 0873801206 is active production, ensuring long-term component availability and supply chain continuity.

Compliance Difference: The 0873801206 is ROHS3 compliant, whereas the 63453-312 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. Systems designed for RoHS-compliant component sourcing should prioritize the Molex alternative.

Dimensional Variance: The 0873801206 has an insulation height of 0.157" (4.00mm) compared to the 63453-312 at 0.177" (4.50mm), and a contact post length of 0.051" (1.30mm) versus 0.098" (2.50mm). These dimensional differences require PCB layout verification to confirm mechanical fit within existing board designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0873801206 directly replace the Amphenol ICC 63453-312 in existing designs?

A: The connectors share identical mating pitch, position count, row spacing, and contact configuration. However, the reduced insulation height (0.157" vs 0.177") and shorter contact post length (0.051" vs 0.098") of the Molex part require verification against PCB footprint and clearance specifications. Physical fit must be confirmed before implementation.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on matching: connector type (receptacle), contact type (female socket), position count (12), mating pitch (0.079"/2.00mm), row configuration (2 rows at 0.079" spacing), mounting method (through-hole), termination type (solder), fastening mechanism (push-pull), and mating contact finish (gold). Deviations in any of these parameters indicate incompatibility.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS compliance relates to material composition and regulatory adherence, not electrical performance. Both connectors are rated for 2A at 200V. The RoHS3 compliance of the Molex part is relevant only for applications subject to RoHS regulatory requirements.

Q: Are there packaging differences between these connectors?

A: The 63453-312 packaging is not specified in available data. The 0873801206 is supplied in tube packaging. Packaging format may affect procurement, handling, and assembly processes but does not impact electrical or mechanical compatibility.

Q: What should be verified before switching to the Molex substitute?

A: Verify PCB footprint compatibility, particularly the reduced insulation height and contact post length of the Molex part. Confirm that existing mating connectors (plugs) are compatible with the 2.00mm pitch and 2-row configuration. Review application requirements for RoHS compliance applicability.
