Substitute Part Grouping Explanation

Substitution for the 54101-T06-04 is determined by the following critical parameters:

Pitch and Position Count: 0.100" (2.54mm) pitch with 4 positions in a single row
Connector Type and Style: Header configuration for board-to-board connection
Mounting and Termination: Through-hole solder termination with push-pull fastening
Contact Configuration: Male pins with square contact shape
Electrical Performance: 3A current rating per contact
Environmental Compliance: UL94 V-0 flammability rating and MSL 1 rating

Substitute parts are grouped into two categories based on contact geometry and finish specifications:

Group 1 - Square Contact, Tin Finish (Primary Substitutes)

Molex 0423751246, 0423751350, 0423752488, 0423752523
3M 2304-6111-TB, 2304-6111-TP

Group 2 - Circular Contact, Gold or Tin Finish (Alternative Substitutes)

Mill-Max 350-10-104-00-006000
Preci-Dip 350-10-104-00-013101, 350-10-104-01-666101, 350-80-104-00-013101

All substitute parts maintain the core electrical and mechanical compatibility: 0.100" pitch, 4-position single-row configuration, through-hole solder termination, and push-pull fastening. Variations in contact finish (tin vs. gold), contact shape (square vs. circular), and post length accommodate different application requirements while preserving mating interface compatibility.

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select from Molex KK254 series (0423751246, 0423751350, 0423752488, 0423752523), Mill-Max 350-10-104-00-006000, or Preci-Dip 350 series parts. All are ROHS3 compliant and suitable for new designs subject to RoHS regulations.

For Legacy Non-Compliant Applications: The 3M 2304 series (2304-6111-TB, 2304-6111-TP) maintains RoHS non-compliant status matching the original 54101-T06-04, appropriate for retrofit or maintenance of existing equipment where RoHS compliance is not required.

For Extended Temperature Range: Preci-Dip 350 series parts (350-10-104-00-013101, 350-10-104-01-666101, 350-80-104-00-013101) and the original Amphenol ICC part support -55°C to 125°C operation. The 3M 2300 series is limited to -55°C to 105°C.

For Contact Finish Selection: Tin-finished contacts (Molex 0423751246, 0423751350; Preci-Dip 350-80-104-00-013101) provide cost-effective substitution with equivalent electrical performance. Gold-finished contacts (Molex 0423752488, 0423752523; Preci-Dip 350-10-104-00-013101, 350-10-104-01-666101) offer enhanced corrosion resistance for demanding environments.

For Contact Geometry: Square-contact substitutes (Molex series) provide direct mechanical compatibility with existing mating connectors designed for the original part. Circular-contact alternatives (Mill-Max, Preci-Dip) require verification of mating connector compatibility.

Frequently Asked Questions (FAQ)

Q: Can Molex KK254 series parts directly replace the Amphenol ICC 54101-T06-04?

A: Yes. Molex 0423751246, 0423751350, 0423752488, and 0423752523 are direct substitutes. All maintain 0.100" pitch, 4-position single-row configuration, square contact geometry, and push-pull fastening. Verify mating connector compatibility with your specific application.

Q: What is the difference between Molex 0423751350 and 0423752488?

A: The primary differences are contact finish and post length. Part 0423751350 features tin-finished mating contacts with 0.135" post length. Part 0423752488 features gold-finished mating contacts with 0.153" post length. Both are electrically equivalent but suited to different environmental requirements.

Q: Are Preci-Dip 350 series parts compatible with the original Amphenol ICC connector?

A: Preci-Dip 350 series parts feature circular contact geometry, differing from the square contacts of the original part. Compatibility depends on the mating connector design. Verify that your mating connector accepts circular pins before substitution.

Q: Which substitute part is best for new RoHS3-compliant designs?

A: Molex 0423751246 or 0423751350 are recommended for new designs. Both are ROHS3 compliant, widely available, and provide square contact geometry matching common mating connectors. Select 0423751246 for standard applications or 0423751350 for kinked-pin termination if required.

Q: Does the 3M 2300 series offer any advantages over Molex alternatives?

A: The 3M 2300 series maintains RoHS non-compliant status, matching the original part's regulatory classification. This is advantageous for retrofit applications where regulatory consistency is required. However, for new designs, ROHS3-compliant alternatives are preferred.

Q: What is the significance of the "Breakaway" connector type in Molex parts?

A: Breakaway designation indicates that individual positions can be separated from the connector body. This feature provides design flexibility for applications requiring modular connector configurations. The mating interface remains compatible with standard 0.100" pitch connectors.

Q: Can I use gold-finished contacts (Molex 0423752488) in place of tin-finished contacts (Molex 0423751246)?

A: Yes, electrically and mechanically. Gold-finished contacts provide superior corrosion resistance and are suitable for high-reliability applications. However, gold-finished parts typically cost more. Select based on environmental exposure and reliability requirements.

Q: Are there any packaging differences between substitute parts?

A: Yes. Molex parts are supplied in bulk packaging, Mill-Max in tube packaging, and Preci-Dip in bulk packaging. Amphenol ICC and 3M packaging specifications are not provided. Verify packaging requirements for your procurement and assembly processes.

Q: What is the current rating for Molex KK254 series parts?

A: Current rating is not specified in the provided data for Molex parts. However, the original Amphenol ICC part is rated at 3A per contact. Consult Molex datasheets to confirm current ratings for your specific application requirements.

Q: Is the Preci-Dip 350-10-104-01-666101 suitable for press-fit PCB assembly?

A: Yes. This part supports both press-fit and solder termination, providing flexibility for different assembly methods. Verify that your PCB design and assembly process are compatible with press-fit technology before selection.
