Substitute Part Grouping Explanation

Substitution of the M40-6002146 with the M40-6002146R is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for connector type, position count, pitch, row configuration, mounting method, contact finish, stacking heights, and board clearance. The substitution is valid because:

• Connector type and contact configuration are identical (Plug, Center Strip Contacts)
• Electrical interface parameters match exactly (21 positions, 1.00mm pitch, 2 rows)
• Mechanical form factor is preserved (4.3mm mated stacking height, 3.30mm height above board)
• Contact material and finish specifications are identical (Tin, 80.0µin thickness)
• Compliance certifications are equivalent (ROHS3, REACH Unaffected, MSL 1)
• Base product number remains M40-600, confirming series compatibility

The primary distinction is product status: M40-6002146 is obsolete, while M40-6002146R is active. The M40-6002146R includes enhanced packaging (Tape & Reel) and additional features (Pick and Place capability) suitable for automated assembly environments.

Parameter Comparison

Engineering Selection Recommendations

The M40-6002146R is the appropriate selection for new designs and production continuity. As an active product with identical electrical and mechanical specifications, it provides direct functional equivalence to the obsolete M40-6002146. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

The Tape & Reel packaging of the M40-6002146R supports automated pick-and-place assembly processes, offering manufacturing efficiency advantages over standard packaging. The addition of Pick and Place features in the substitute part enhances compatibility with modern surface mount assembly workflows without altering the connector's core electrical or mechanical interface.

For applications currently using M40-6002146, direct substitution with M40-6002146R requires no design modifications, as all critical parameters remain unchanged. Inventory transition from the obsolete part to the active substitute can proceed without circuit board redesign or connector interface alterations.

Frequently Asked Questions (FAQ)

Q: Can M40-6002146R be used as a direct replacement for M40-6002146?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, mounting method, contact finish, and stacking heights. The primary difference is product status and packaging format.

Q: What is the significance of the "R" designation in M40-6002146R?

A: The "R" suffix indicates Tape & Reel packaging, which is standard for automated assembly environments. This packaging format does not affect the connector's electrical or mechanical performance.

Q: Are there any compliance differences between the two parts?

A: No. Both M40-6002146 and M40-6002146R maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 ratings.

Q: Why is M40-6002146 classified as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation. The M40-6002146R serves as the active continuation of this connector line within the M40 series.

Q: Will substituting M40-6002146R require PCB layout changes?

A: No. The substitute part maintains identical mechanical form factor and mounting specifications, requiring no modifications to existing circuit board designs or connector footprints.

Q: What is the difference in features between the two parts?

A: M40-6002146 includes Board Guide and Solder Retention features. M40-6002146R includes Board Guide, Pick and Place, and Solder Retention features. The additional Pick and Place feature supports automated assembly but does not affect electrical or mechanical compatibility.
