Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet UL94 V-0 flammability requirements, ensuring compliance with standard safety specifications for rectangular connectors in this category.

Tin-Plated Mating Surface Substitutes: The Molex 0423751246, Harwin M20-9770446, and Sullins PBC04SAAN and PBC04SABN variants provide tin-plated mating surfaces equivalent to the primary part. These options are suitable for applications where tin plating is specified or preferred for solderability and cost considerations.

Gold-Plated Mating Surface Substitutes: The Mill-Max 350-10-104-00-006000, TE Connectivity 5-146281-4, Harwin M20-9990445, and Sullins PBC04SAAN, PBC04SACN, and PBC04SADN variants feature gold-plated mating surfaces. Gold plating provides enhanced corrosion resistance and is specified for applications requiring superior contact reliability in harsh environments or extended storage conditions.

Temperature Range Considerations: The primary part and Sullins variants support -65°C to 125°C operation. The TE Connectivity 5-146281-4 and Harwin M20 series support -65°C to 105°C and -40°C to 105°C respectively. Selection should account for application temperature extremes.

Contact Length Variations: Sullins PBC04SABN, PBC04SACN, and PBC04SADN provide extended post lengths (0.230", 0.320", and 0.420" respectively) for applications requiring deeper PCB penetration or stacking configurations. Standard post length variants (0.120" to 0.125") are suitable for conventional single-board applications.

Breakaway and Cuttable Features: Molex, TE Connectivity, Harwin, and Sullins variants offer breakaway or cuttable connector options, enabling field customization of position count when full 4-position headers are not required.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Amphenol ICC 54101-T0804LF with any of the listed parts directly?

A: Yes, all listed parts maintain the core specifications required for functional compatibility: 0.100" (2.54mm) pitch, 4-position single-row configuration, male pin contacts, through-hole mounting, solder termination, and push-pull fastening. Direct substitution is mechanically and electrically feasible. Verify contact length and finish specifications against your PCB design requirements.

Q: What is the difference between tin-plated and gold-plated mating surfaces?

A: Tin plating (100.0µin / 2.54µm on the primary part) provides cost-effective solderability and is suitable for standard applications. Gold plating (10.0µin to 30.0µin / 0.25µm to 0.76µm on substitute parts) offers superior corrosion resistance, extended shelf life, and enhanced contact reliability in demanding environments. Gold-plated contacts are specified for applications with extended storage, high humidity exposure, or critical signal integrity requirements.

Q: Why do some substitute parts have different contact post lengths?

A: Contact post length determines the depth of PCB penetration and is selected based on PCB thickness and stacking height requirements. Standard post lengths (0.120" to 0.125") accommodate typical single-board applications. Extended post lengths (0.230" to 0.420") are specified for multi-board stacking, thick PCB assemblies, or applications requiring deeper mechanical engagement.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts are RoHS compliant (RoHS or ROHS3 status). The primary part is RoHS Compliant, and all substitutes meet either RoHS or ROHS3 standards, ensuring compliance with lead-free and hazardous substance restrictions.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: MSL 1 (Unlimited) indicates that the connector has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. All primary and substitute parts carry MSL 1 or Not Applicable ratings, indicating unrestricted shelf life and standard handling protocols.

Q: Can I use a substitute part with a different operating temperature range?

A: The primary part supports -65°C to 125°C operation. Substitute parts with narrower temperature ranges (-40°C to 105°C or -65°C to 105°C) are suitable only if your application operates within those limits. Verify that the selected substitute meets your system's minimum and maximum operating temperature requirements.

Q: What connector types are available among the substitutes?

A: The primary part is a standard header. Substitute options include breakaway variants (Molex, TE Connectivity, Sullins) that allow individual position separation, and cuttable variants (Harwin) that enable field customization of position count. Standard unshrouded headers are available across all manufacturers.

Q: How do I determine which substitute is best for my application?

A: Selection depends on three primary factors: (1) contact finish requirement (tin or gold plating), (2) contact post length for PCB thickness compatibility, and (3) operating temperature range. Cross-reference these parameters against your design specifications. All parts maintain identical pitch, position count, and fastening characteristics, ensuring mechanical and electrical interchangeability within these parameter constraints.
