Substitute Part Grouping Explanation

The TE Connectivity 5120638-1 qualifies as a direct substitute for the 120638-1 based on alignment of critical electrical and mechanical parameters. Both parts share identical specifications for connector type, position count, pitch, row configuration, mounting method, termination style, connector usage, contact finish, and operating temperature range.

The substitution is valid when the following parameters match between the main part and substitute:

• Connector Type: Header, Male Pins
• Number of Positions: 144
• Pitch: 0.079" (2.00mm)
• Number of Rows: 12
• Mounting Type: Through Hole
• Termination: Press-Fit
• Connector Usage: Backplane
• Contact Finish: Gold
• Operating Temperature: -55°C ~ 125°C
• Connector Style: B 12
• Series: Z-PACK

The primary distinction between these parts is packaging format and compliance certification status, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 120638-1 and 5120638-1 are active production parts from TE Connectivity AMP Connectors, confirming ongoing manufacturer support and availability. The parts are functionally equivalent for backplane connector applications based on matching electrical and mechanical specifications.

The 5120638-1 substitute part offers ROHS3 compliance, whereas the 120638-1 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. Both parts maintain identical Moisture Sensitivity Level (MSL 1) and export classification (EAR99).

Selection between these parts should be based on regulatory compliance requirements for the end application. The 5120638-1 is the appropriate choice for designs requiring RoHS3 compliance. Both parts share identical connector geometry, electrical ratings, and environmental operating specifications, ensuring direct functional interchangeability in circuit designs where compliance status is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the 5120638-1 be used as a direct replacement for the 120638-1 in existing designs?

A: Yes. The 5120638-1 is functionally equivalent to the 120638-1 for backplane connector applications.
