Amphenol ICC 54101-S08-04 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54101-S08-04 is a rectangular connector header with 4 positions at 0.100" (2.54mm) pitch, designed for through-hole board-to-board applications. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The connector features unshrouded male pins with gold-plated mating contacts, phosphor bronze material, and a current rating of 3A per contact. Substitute parts must maintain compatibility across pitch, position count, mounting type, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54101-S08-04 is determined by strict adherence to the following parameters:

• Connector type must be Header
• Contact type must be Male Pin
• Number of positions must be 4
• Number of rows must be 1
• Pitch must be 0.100" (2.54mm)
• Mounting type must be Through Hole
• Termination must be Solder
• Fastening type must be Push-Pull
• Shrouding must be Unshrouded
• Material flammability rating must be UL94 V-0
• Insulation color must be Black

The following parts meet these criteria and are qualified as direct substitutes: Molex 0423752488, 3M 2304-6111-TB, 3M 2304-6111-TP, Samtec TS-104-G-A-1, and Samtec TS-104-T-AA.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts maintain the core functional parameters required for direct replacement of the 54101-S08-04. Selection should be based on product status, regulatory compliance, and application requirements.

For new designs requiring RoHS3 compliance, the Molex 0423752488, Samtec TS-104-G-A-1, and Samtec TS-104-T-AA are compliant options. The Molex part offers the additional feature of breakaway capability and is available in bulk packaging with 854 units in stock. The Samtec TS-104-T-AA provides the highest inventory availability at 5112 units and maintains ROHS3 compliance with tin contact finish.

For applications where RoHS compliance is not required, the 3M 2304-6111-TB and 2304-6111-TP remain viable alternatives with active product status. The 3M 2304-6111-TB features gold mating contact finish with tin-lead post finish, while the 2304-6111-TP uses tin-lead for both mating and post contacts.

The Samtec TS-104-G-A-1 provides gold contact finish with ROHS3 compliance and 1147 units in stock. The contact finish thickness of 20.0µin (0.51µm) falls between the original specification and other alternatives.

Operating temperature range differs between options. The original 54101-S08-04 operates from -65°C to 125°C, while the 3M parts operate from -55°C to 105°C. Applications requiring the full -65°C to 125°C range should confirm compatibility with the selected substitute.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0423752488 be used as a direct replacement for the Amphenol ICC 54101-S08-04?

A: Yes. The Molex 0423752488 meets all critical substitution parameters: 4-position, 0.100" pitch, through-hole solder termination, unshrouded male pin header with push-pull fastening and UL94 V-0 flammability rating. The part is active and ROHS3 compliant. Minor dimensional variations exist in contact length and insulation height, but these do not affect functional compatibility.

Q: What is the difference between the Samtec TS-104-G-A-1 and TS-104-T-AA?

A: Both are 4-position, 0.100" pitch through-hole headers with identical core specifications. The primary difference is contact finish: TS-104-G-A-1 uses gold finish with 20.0µin thickness, while TS-104-T-AA uses tin finish with 200.0µin thickness. Both are ROHS3 compliant. Selection depends on application requirements for contact material and corrosion resistance.

Q: Are the 3M 2304-6111-TB and 2304-6111-TP interchangeable?

A: Both parts share identical mechanical and electrical specifications with one exception: contact finish. The 2304-6111-TB features gold mating contacts with tin-lead post finish, while the 2304-6111-TP uses tin-lead for both mating and post contacts. Both operate at -55°C to 105°C and carry 3A current rating. Selection depends on contact material requirements for the application.

Q: Does the operating temperature range difference affect substitution?

A: The original 54101-S08-04 operates from -65°C to 125°C. The 3M parts (2304-6111-TB and 2304-6111-TP) operate from -55°C to 105°C. For applications requiring operation below -55°C or above 105°C, the 3M parts are not suitable. The Molex and Samtec parts do not specify operating temperature range in the provided data.

Q: What packaging options are available?

A: The Molex 0423752488 is supplied in bulk packaging. The Samtec TS-104-G-A-1 and TS-104-T-AA are supplied in bulk packaging. The 3M and Amphenol ICC parts do not specify packaging type in the provided data. Verify packaging requirements with supplier documentation.

Q: Which substitute offers the best inventory availability?

A: The Samtec TS-104-T-AA provides the highest inventory with 5112 units in stock. The Samtec TS-104-G-A-1 has 1147 units available. The Molex 0423752488 has 854 units, and the 3M parts have 791 and 777 units respectively.

Q: Are all substitutes RoHS compliant?

A: No. The Molex 0423752488, Samtec TS-104-G-A-1, and Samtec TS-104-T-AA are ROHS3 compliant. The 3M 2304-6111-TB and 2304-6111-TP are RoHS non-compliant, matching the original 54101-S08-04 status. For applications requiring RoHS compliance, select from the Molex or Samtec options.
