Amphenol ICC 63453-340 Rectangular Connector – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-340 is a 40-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, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility within the Minitek® 2.00mm connector family and cross-manufacturer alternatives.

Engineering Selection Recommendations

Primary Substitute – Direct Amphenol ICC Replacement: The 63453-340LF is the direct active equivalent from Amphenol ICC. It maintains identical electrical and mechanical specifications to the obsolete 63453-340, with the addition of RoHS compliance and REACH applicability. This part is recommended as the first-choice replacement for direct substitution without design modification.

Cross-Manufacturer Alternatives – Full Compatibility: The following parts meet all critical substitution parameters and are suitable for direct replacement:

Molex 0791077019 (Milli-Grid 79107 series): Active status with full electrical compatibility. Operating temperature range matches the original specification. Voltage rating of 125V is lower than the original 200V; current rating of 1A is lower than the original 2A. Suitable for applications not exceeding these electrical limits.
TE Connectivity 4-1734506-3 (AMPMODU series): Active status with UL94 V-0 flammability rating. Voltage rating of 250VAC exceeds the original specification. Operating temperature range of -40°C to 105°C is narrower than the original -55°C to 125°C. Suitable for applications within this temperature window.
Harwin M22-7142042 (M22 series): Active status with ROHS3 compliance. Voltage rating of 500VAC significantly exceeds the original specification. Operating temperature range of -40°C to 105°C is narrower than the original. Current rating of 2A matches the original. Suitable for high-voltage applications within the specified temperature range.
Samtec MMS-120-01-F-DV (MMS series): Active status with ROHS3 compliance. Current rating of 3.9A per contact exceeds the original 2A specification. Operating temperature range of -55°C to 125°C matches the original. Suitable for applications requiring higher current capacity.

Secondary Alternatives – Partial Compatibility Considerations: The Mill-Max 833-13-040-10-002000 meets all critical mechanical parameters but features a circular contact shape (versus square) and beryllium copper contact material (versus phosphor bronze). This part is not RoHS compliant. Substitution requires verification of contact geometry compatibility with existing mating connectors.

The Samtec MMS-120-01-H-DV and MMS-120-01-L-DV variants (01, 10, 12) feature 39 positions loaded instead of 40, making them unsuitable for direct replacement in applications requiring all 40 positions.

Frequently Asked Questions (FAQ)

Q: Can the 63453-340 be directly replaced with the 63453-340LF? A: Yes. The 63453-340LF is the active equivalent from the same manufacturer with identical electrical and mechanical specifications. The primary difference is RoHS compliance status. Direct substitution is recommended without design modification.

Q: What is the key difference between the Amphenol ICC 63453-340LF and the Molex 0791077019? A: Both maintain the 40-position, 2.00mm pitch, through-hole solder configuration. The Molex part has a lower voltage rating (125V versus 200V) and lower current rating (1A versus 2A). Substitution is valid only for applications operating within these lower electrical limits.

Q: Are the Samtec MMS-120-01-F-DV and MMS-120-01-H-DV interchangeable? A: Both are 40-position, 2.00mm pitch receptacles with identical mechanical dimensions. The primary difference is contact finish on the post: MMS-120-01-F-DV uses tin finish, while MMS-120-01-H-DV uses gold finish. They are electrically and mechanically interchangeable; selection depends on post finish requirements.

Q: Why are the Samtec MMS-120-01-L-DV variants (01, 10, 12) not suitable replacements? A: These variants have only 39 positions loaded instead of 40. They are not suitable for applications requiring all 40 contact positions. Use only if the application design permits a single missing position.

Q: What is the significance of the contact shape difference in the Mill-Max 833-13-040-10-002000? A: The Mill-Max part features circular contacts instead of square contacts. While the mating pitch and row spacing are identical, the contact geometry may not be compatible with existing mating connectors designed for square contacts. Verification of mating connector specifications is required before substitution.

Q: Does the operating temperature range affect substitution decisions? A: Yes. The original 63453-340 operates from -55°C to 125°C. Substitutes with narrower ranges (such as TE Connectivity 4-1734506-3 and Harwin M22-7142042, both -40°C to 105°C) are suitable only for applications operating within these limits. For applications requiring the full -55°C to 125°C range, select substitutes matching this specification.

Q: Are RoHS-compliant substitutes required? A: The original 63453-340 is RoHS non-compliant. If RoHS compliance is required for new designs or regulatory purposes, select from active substitutes with RoHS or ROHS3 compliance status, such as 63453-340LF, 0791077019, 4-1734506-3, M22-7142042, or Samtec MMS series parts.

Q: What packaging considerations apply to these substitutes? A: The original part has unspecified packaging. Substitutes are available in Tube (63453-340LF, 0791077019, M22-7142042, MMS-120-01-F-DV), Tray (4-1734506-3), or Bulk (833-13-040-10-002000) packaging. Packaging selection affects procurement quantity and handling requirements but does not affect electrical or mechanical compatibility.
