Amphenol ICC 54101-S3003LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54101-S3003LF is an active-status vertical header connector from the BERGSTIK® series, designed for through-hole board-to-board applications. This 3-position connector operates at 0.100" (2.54mm) pitch with male pin contacts and solder termination. The part is RoHS compliant, REACH affected, and maintains unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design compatibility across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54101-S3003LF is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) - exact match required
• Number of Positions: 3 - exact match required
• Number of Rows: 1 - exact match required
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• Shrouding: Unshrouded
• Contact Shape: Square

The three substitute parts identified (9-146276-0-03, 929700-11-03-RK, and 929705-01-03-EU) meet these core electrical and mechanical requirements. Variations in contact finish, insulation material, and operating temperature ranges are secondary parameters that do not prevent functional substitution but require design review for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet UL94 V-0 flammability requirements. The 9-146276-0-03 (TE Connectivity AMPMODU Mod II) provides the closest operating temperature range alignment (-65°C ~ 105°C) and maintains the 3A current rating of the original part. The 929700-11-03-RK and 929705-01-03-EU (both 3M 929 series) operate within a narrower temperature range (-40°C ~ 105°C) and support 2.5A current rating, which represents a reduction from the original 3A specification.

Contact post length variations across substitutes range from 0.110" to 0.125", with overall contact lengths spanning 0.528" to 0.543". These dimensional differences fall within typical manufacturing tolerances for through-hole solder applications but require PCB design verification to confirm pad depth compatibility.

The 9-146276-0-03 achieves ROHS3 compliance, while the original part and 3M alternatives maintain RoHS compliance. All parts carry EAR99 export classification and identical HTSUS codes, supporting consistent supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the 929700-11-03-RK or 929705-01-03-EU be used in applications requiring the full -65°C to 125°C operating range?

A: No. The 3M 929 series parts operate only to -40°C minimum and 105°C maximum. Applications requiring the full -65°C to 125°C range must use either the original 54101-S3003LF or the TE Connectivity 9-146276-0-03.

Q: What is the impact of the reduced current rating on the 3M substitutes?

A: The 929700-11-03-RK and 929705-01-03-EU support 2.5A per contact versus the original 3A rating. Applications operating at or below 2.5A per contact are unaffected. Designs requiring 3A per contact must use the 54101-S3003LF or 9-146276-0-03.

Q: Are the contact post length variations significant for PCB compatibility?

A: Contact post lengths range from 0.110" (929705-01-03-EU) to 0.125" (9-146276-0-03 and 929700-11-03-RK), compared to 0.120" on the original part. These variations are within standard through-hole solder pad depth tolerances but require verification against specific PCB design specifications.

Q: Do all substitutes support breakaway functionality?

A: The TE Connectivity 9-146276-0-03 and both 3M 929 series parts are specified as Header, Breakaway connectors, enabling individual position separation. The original 54101-S3003LF is specified as Header only. Breakaway capability is a functional enhancement that does not prevent substitution.

Q: What are the contact finish differences, and do they affect compatibility?

A: The original part specifies gold or gold GXT™ mating finish at 15.0µin thickness. Substitutes vary: 9-146276-0-03 matches this specification; 929700-11-03-RK uses tin finish at 200.0µin; 929705-01-03-EU uses gold at 10.0µin. All finishes are suitable for standard solder termination and push-pull mating cycles.

Q: Are there insulation material differences that affect performance?

A: The original part does not specify insulation material. Substitutes use Liquid Crystal Polymer (LCP) or Polycyclohexylenedimethylene Terephthalate (PCT). Both materials meet UL94 V-0 flammability requirements and are standard for this connector category.

Q: Do all parts carry identical compliance certifications?

A: All parts are RoHS compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share EAR99 export classification and 8536.69.4040 HTSUS code. The 9-146276-0-03 achieves ROHS3 compliance, representing enhanced regulatory alignment.
