Key Parameters

Substitute Part Grouping Explanation

The M80-5122442 qualifies as a direct substitute for the M80-5122422 based on the following critical parameters:

• Identical connector type, contact type, and position configuration (24-position, 2-row header)
• Matching pitch specifications (0.079" / 2.00mm mating pitch and row spacing)
• Identical mounting type (surface mount) and shrouding design (shrouded 4-wall)
• Matching electrical ratings (2.2A current, 800V voltage)
• Identical operating temperature range (-55°C ~ 125°C)
• Same insulation material and flammability rating (PPS glass-filled, UL94 V-0)
• Identical mated stacking heights and mechanical dimensions

The primary distinction is product status: M80-5122422 is obsolete, while M80-5122442 is active. Additionally, M80-5122442 carries ROHS3 compliance, whereas M80-5122422 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The M80-5122442 is the direct active equivalent for the obsolete M80-5122422. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in board-to-board and cable connector applications.

The M80-5122442 offers the additional advantage of ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The contact finish post material differs (tin versus tin-lead), which aligns with modern lead-free manufacturing standards while maintaining equivalent electrical performance.

For new designs or component refresh cycles, M80-5122442 is the appropriate selection. For legacy systems currently using M80-5122422, substitution with M80-5122442 is mechanically and electrically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Are M80-5122422 and M80-5122442 mechanically interchangeable?

A: Yes. Both parts share identical dimensions, pitch specifications (2.00mm), row spacing, insulation height (0.234"), mated stacking heights, and shrouding design. They are direct mechanical replacements.

Q: What is the difference in contact finish between these parts?

A: M80-5122422 uses tin-lead post finish, while M80-5122442 uses tin post finish. Both maintain equivalent electrical conductivity and contact reliability. The tin finish in M80-5122442 reflects lead-free manufacturing compliance.

Q: Can M80-5122442 be used in applications originally designed for M80-5122422?

A: Yes. The electrical ratings (2.2A, 800V), operating temperature range (-55°C ~ 125°C), and mechanical specifications are identical. M80-5122442 is a direct functional replacement.

Q: Why is M80-5122422 listed as obsolete?

A: M80-5122422 has been superseded by M80-5122442 in the Harwin product line. M80-5122442 is the active production part and is recommended for all new applications.

Q: Does the packaging difference affect compatibility?

A: No. Packaging (tube for M80-5122442 versus unspecified for M80-5122422) affects only procurement and handling, not electrical or mechanical performance.

Q: Is M80-5122442 suitable for RoHS-regulated applications?

A: Yes. M80-5122442 carries ROHS3 compliance certification, making it suitable for applications subject to RoHS directives. M80-5122422 is RoHS non-compliant.
