Substitute Part Grouping Explanation

Substitution between the main part 646573-1 and the identified substitute 5646573-1 is based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical manufacturer: TE Connectivity AMP Connectors
• Identical series: Z-PACK
• Identical connector type: Receptacle, Female Sockets
• Identical number of positions: 110
• Identical pitch: 0.079" (2.00mm)
• Identical number of rows: 5
• Identical connector style: AB 22
• Identical mounting type: Through Hole, Right Angle
• Identical current rating: 1.5 A
• Identical voltage rating: 500Vrms
• Identical operating temperature range: -55°C ~ 125°C
• Identical contact finish: Gold
• Identical connector usage: Backplane

Differing Parameters (Distinguishing Factors):

• Termination method: Solder (646573-1) versus Press-Fit (5646573-1)
• Packaging: Bulk (646573-1) versus Tube (5646573-1)
• RoHS compliance: Non-compliant (646573-1) versus Compliant (5646573-1)
• REACH status: Affected (646573-1) versus Unaffected (5646573-1)

These parts are functionally equivalent for backplane connector applications where the core electrical and mechanical specifications align. Selection between them depends on termination method requirements and regulatory compliance needs.

Parameter Comparison

Engineering Selection Recommendations

646573-1 Selection Criteria:

• Applications requiring solder termination for permanent board attachment
• Designs where bulk packaging is acceptable
• Systems without RoHS compliance mandates
• Applications where REACH-affected materials are permissible

5646573-1 Selection Criteria:

• Applications requiring press-fit termination for reversible or field-replaceable connections
• Designs requiring RoHS compliance certification
• Systems subject to REACH regulatory requirements
• Applications where REACH-unaffected material composition is mandatory
• Tube packaging requirements for automated assembly processes

Both parts maintain identical electrical performance (1.5 A current rating, 500Vrms voltage rating) and mechanical compatibility (110 positions, 2.00mm pitch, 5-row configuration) within the specified operating temperature range of -55°C to 125°C. Selection between these parts is determined by termination method requirements and regulatory compliance obligations specific to the application and end-use market.

Frequently Asked Questions (FAQ)

Q: Can 5646573-1 be used as a direct replacement for 646573-1 in existing designs?

A: Substitution is possible only if the design accommodates press-fit termination instead of solder termination. The press-fit connection method differs fundamentally from solder attachment, requiring compatible PCB pad design and assembly procedures. All other electrical and mechanical parameters are identical.

Q: What is the primary difference between these two connectors?

A: The main difference is the termination method. The 646573-1 uses solder termination for permanent connections, while the 5646573-1 uses press-fit termination for reversible connections. Both connectors share identical position count (110), pitch (2.00mm), current rating (1.5 A), and voltage rating (500Vrms).

Q: Are there compliance differences between these parts?

A: Yes. The 5646573-1 is RoHS Compliant and REACH Unaffected, while the 646573-1 is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations must use the 5646573-1.

Q: Does packaging affect electrical or mechanical performance?

A: No. The difference between Bulk packaging (646573-1) and Tube packaging (5646573-1) affects only handling, storage, and assembly automation compatibility. Electrical and mechanical specifications remain identical.

Q: Are the contact finishes identical?

A: Yes. Both connectors feature gold contact finish. The 646573-1 specifies 30.0µin (0.76µm) thickness, while the 5646573-1 does not specify thickness in the provided data.

Q: Can these connectors be used interchangeably in backplane applications?

A: Interchangeability depends on the specific termination method required by the PCB design. If the design requires solder termination, only 646573-1 is suitable. If the design requires press-fit termination, only 5646573-1 is suitable. The connectors cannot be mixed within the same application.

Q: What is the operating temperature range for both parts?

A: Both connectors operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.
