Equivalent & Substitute Parts for Amphenol ICC (FCI) 75403-003

Part Overview

The Amphenol ICC (FCI) 75403-003 is a Single Post Terminal Connector, part of the Bergpin® series, designed for through-hole mounting and solder termination. This PC pin features a gold-plated 0.025" (0.64mm) square post, suitable for board thicknesses between 0.062" and 0.125" (1.57mm ~ 3.18mm). The product is currently active but is classified as RoHS non-compliant, requiring alternatives for applications needing RoHS compliance. Identifying substitute models is necessary when environmental regulations or certification standards mandate RoHS-compliant components.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined strictly by matching all functional, mechanical, and compliance parameters. Key substitution criteria include:

• Manufacturer and series consistency
• Terminal type and style
• Pin dimensions above and below flange
• Overall length
• Mounting hole diameter and board thickness range
• Mounting type and termination method
• Contact material, finish, and finish thickness
• Insulation status
• RoHS and compliance attributes

Only parts that meet all listed parameters are grouped as direct substitutes. In this case, 75403-003LF matches all required criteria with the added benefit of RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection between 75403-003 and 75403-003LF is determined by required RoHS compliance: 75403-003 is RoHS non-compliant and suitable for applications where this certification is not mandatory, while 75403-003LF is RoHS compliant, meeting requirements for environmentally regulated designs. Both parts are classified as active and offer an unlimited Moisture Sensitivity Level (MSL 1). All other functional and dimensional parameters are equivalent.

Frequently Asked Questions (FAQ)

Q1: What are the criteria for choosing substitute parts for 75403-003?
A1: Substitute parts must match the terminal type, pin dimensions, termination method, contact material and finish, insulation status, mounting specifications, and compliance attributes as listed in the parameter table.

Q2: Is 75403-003LF fully compatible as a direct substitute?
A2: Yes. 75403-003LF matches all mechanical, electrical, and mounting specifications of 75403-003, with the addition of RoHS compliance.

Q3: Are there differences in packaging between 75403-003 and 75403-003LF?
A3: Both parts are provided in Tape & Reel (TR) packaging as specified.

Q4: Can board thickness specifications affect substitute compatibility?
A4: Both parts support board thicknesses from 0.062" to 0.125" (1.57mm ~ 3.18mm), and substitutes are selected only if matching these values.

Q5: Why might RoHS status influence part selection?
A5: Applications subject to environmental regulations or certifications require components that are RoHS compliant; therefore, selection of 75403-003LF is necessary in these cases.
