Key Parameters

Substitute Part Grouping Explanation

The 55623-050LF qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Card Type: Both parts are PCMCIA connectors
• Number of Positions: Both feature 68 positions
• Connector Type: Both are stacked connectors with ejector mechanism
• Mounting Type: Both are card edge headers
• Height Above Board: Both measure 0.654" (16.60mm)
• Contact Finish: Both use gold plating at 3.94µin (0.10µm) thickness
• Features: Both include card guides
• Insertion/Removal Method: Both support push in/push out operation
• Mounting Feature: Both use normal, standard top mounting

The primary distinction between these parts is product status and RoHS compliance, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 55623-050LF is the direct functional equivalent of the 55623-050. Selection between these parts should be based on the following criteria:

Use 55623-050LF when:

• RoHS compliance is required for new designs or regulatory requirements
• Active product support and availability from the manufacturer is necessary
• Long-term component sourcing stability is a priority

Use 55623-050 when:

• Legacy system maintenance requires exact original part matching
• RoHS compliance is not a design constraint
• Existing inventory of the original part is available

Both parts share identical electrical and mechanical specifications for PCMCIA card edge connector applications. The choice between them is determined by compliance requirements and product lifecycle status, not by functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 55623-050 and 55623-050LF electrically interchangeable?

A: Yes. Both parts feature identical contact configurations, gold plating specifications, and electrical characteristics for 68-position PCMCIA card edge applications.

Q: What is the significance of the "LF" suffix in the 55623-050LF part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance. The 55623-050LF meets RoHS requirements, while the 55623-050 does not.

Q: Can the 55623-050LF be used as a direct replacement in designs originally specified for the 55623-050?

A: Yes. The 55623-050LF is mechanically and electrically compatible with the 55623-050. All critical parameters including connector type, position count, mounting configuration, and contact specifications are identical.

Q: What is the difference in packaging between these parts?

A: The 55623-050LF is supplied in tray packaging. The packaging specification for the 55623-050 is not provided in the available data.

Q: Why is the 55623-050 classified as obsolete?

A: The obsolete status reflects the manufacturer's discontinuation of this part number. The 55623-050LF represents the current active equivalent with RoHS compliance.

Q: Are there any height or mounting differences between these connectors?

A: No. Both parts measure 0.654" (16.60mm) above the board and use identical normal, standard top mounting configurations.

Q: What certifications apply to both parts?

A: Both parts carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The 55623-050LF additionally meets RoHS compliance requirements.
