Key Parameters

Substitute Part Grouping Explanation

Substitution for the 75543-014 is determined by strict equivalence across the following parameters:

• Series Compatibility: Both parts must belong to the Mini-PV™ Basics+ series
• Contact Configuration: Socket contact type required
• Wire Gauge Range: 32-36 AWG specification must be maintained
• Termination Method: Crimp termination only
• Contact Finish: Gold plating with 30.0µin (0.76µm) thickness
• Base Product Number: 75543 family designation

The substitute part 75543-014LF meets all these criteria and is the direct equivalent for the obsolete 75543-014.

Parameter Comparison

Engineering Selection Recommendations

The 75543-014LF is the direct functional equivalent to the obsolete 75543-014. Both parts share identical electrical and mechanical specifications across all critical parameters: series designation, contact configuration, wire gauge range, termination method, and contact finish properties.

The primary distinction between these parts is regulatory compliance status. The 75543-014LF carries active product status and is RoHS compliant, whereas the 75543-014 is obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance documentation, the 75543-014LF is the appropriate selection. The REACH Affected status of the 75543-014LF indicates it is subject to REACH regulations, which may be relevant for applications in regulated markets.

Both parts are classified under ECCN EAR99 and HTSUS 8536.90.4000, indicating equivalent export and tariff classifications.

Frequently Asked Questions (FAQ)

Q: Can 75543-014LF be used as a direct replacement for 75543-014?

A: Yes. The 75543-014LF is electrically and mechanically equivalent to the 75543-014. Both are socket contacts for the Mini-PV™ Basics+ series with identical wire gauge (32-36 AWG), crimp termination, and gold contact finish specifications.

Q: What is the significance of the "LF" designation in 75543-014LF?

A: The "LF" suffix indicates lead-free composition, which aligns with RoHS compliance requirements. This is the primary distinction between the obsolete 75543-014 and the active 75543-014LF.

Q: Are there packaging differences between these parts?

A: The 75543-014 packaging is not specified in the available data. The 75543-014LF is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts maintain identical contact finish thickness (30.0µin / 0.76µm) and gold plating specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
