Engineering Selection Recommendations

The M80-7530842 is the designated manufacturer substitute for the obsolete M80-8550822. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The substitute part carries active product status with confirmed inventory availability, providing supply chain continuity for applications currently using the M80-8550822. The electrical and mechanical specifications remain functionally equivalent across all critical parameters governing connector interchangeability.

The voltage rating increase from 120V to 800V in the substitute part represents an enhancement that does not restrict application compatibility. The contact post finish change from tin-lead to tin reflects current manufacturing practices and maintains equivalent solder joint reliability.

Frequently Asked Questions (FAQ)

Q: Can M80-7530842 directly replace M80-8550822 in existing designs?

A: Yes. Both parts share identical pitch, position count, row configuration, mounting method, and shrouding design. The electrical and mechanical interface specifications are equivalent, supporting direct substitution in board-to-board and cable connector applications.

Q: What is the difference between "Plug" and "Header" connector types listed for these parts?

A: The M80-8550822 is classified as a plug connector, while M80-7530842 is classified as a header. Both are male pin contact configurations within the Datamate L-Tek series and maintain compatible mating interfaces with standard receptacle components.

Q: Does the voltage rating difference affect substitution suitability?

A: No. The M80-7530842 voltage rating of 800V exceeds the M80-8550822 specification of 120V. This represents a performance enhancement that does not restrict compatibility in applications designed for the original 120V specification.

Q: Are there packaging differences between these parts?

A: The M80-8550822 packaging is not specified in available data. The M80-7530842 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the contact post finish change from tin-lead to tin?

A: The M80-7530842 uses tin finish on contact posts, replacing the tin-lead finish of the M80-8550822. Both finishes provide equivalent solder joint formation and reliability. The tin finish reflects current manufacturing standards and RoHS compliance requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both M80-8550822 and M80-7530842 carry ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.
