Substitute Part Grouping Explanation

Substitution of the 68020-616 is determined by strict equivalence across the following critical parameters:

Connector type (Header, male pin configuration)
Pitch specification (0.100" / 2.54mm mating pitch)
Position count and row configuration (16 positions, 2 rows)
Row spacing (0.100" / 2.54mm)
Mounting method (Through hole, right angle)
Termination type (Solder)
Current rating (3A per contact minimum)
Flammability compliance (UL94 V-0)

The Harwin Inc. M20-9740846 meets all these critical parameters and is identified as the manufacturer-recommended substitute. This part maintains functional and mechanical compatibility while offering active product status and improved compliance certifications.

Engineering Selection Recommendations

The M20-9740846 is the designated substitute for the obsolete 68020-616. Selection of this alternative is supported by the following factors:

Product Status: The 68020-616 is obsolete, whereas the M20-9740846 maintains active product status, ensuring long-term availability and manufacturing support.

Compliance Certifications: The M20-9740846 is ROHS3 compliant and REACH unaffected, providing superior regulatory alignment compared to the non-compliant 68020-616. Both parts maintain UL94 V-0 flammability certification.

Functional Equivalence: Both connectors share identical mating pitch, position count, row configuration, mounting method, termination type, and current rating specifications. These parameters ensure direct mechanical and electrical compatibility in board-to-board applications.

Operating Temperature Consideration: The 68020-616 operates across -65°C to 125°C, while the M20-9740846 operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C require thermal performance verification against specific design requirements.

Physical Dimensions: Minor variations exist in contact length and insulation height. The M20-9740846 features a longer post length (0.118" vs. 0.095") and slightly greater insulation height (0.200" vs. 0.190"), which may require PCB layout verification for clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can the M20-9740846 be used as a direct replacement for the 68020-616 in existing designs?

A: The M20-9740846 is functionally equivalent for mating pitch, position count, row spacing, mounting type, and current rating. However, verify PCB layout clearances due to differences in post length (0.118" vs. 0.095") and insulation height (0.200" vs. 0.190"). Confirm operating temperature requirements, as the M20-9740846 operates to 105°C maximum versus 125°C for the 68020-616.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete vs. active), compliance certifications (RoHS non-compliant vs. ROHS3 compliant), contact material (phosphor bronze vs. brass), contact finish (gold vs. tin), and operating temperature range (-65°C to 125°C vs. -40°C to 105°C). Mating pitch, position count, and current rating are identical.

Q: Are there any compatibility concerns with the contact finish difference?

A: The 68020-616 features gold-plated contacts (30.0µin thickness), while the M20-9740846 features tin-plated contacts. Both finishes are suitable for solder termination and push-pull mating applications. Contact finish selection does not affect mechanical compatibility or current-carrying capacity at the specified 3A per contact rating.

Q: Does the cuttable feature of the M20-9740846 affect compatibility?

A: The cuttable feature of the M20-9740846 is an additional capability that does not impact compatibility with the 68020-616. Both connectors maintain identical mating pitch and position spacing, ensuring equivalent performance in fixed 16-position configurations.

Q: What should be verified before implementing the M20-9740846 as a substitute?

A: Verify PCB layout clearances for the increased post length and insulation height. Confirm that the operating temperature range of -40°C to 105°C meets application requirements. Validate that ROHS3 compliance and tin contact finish are acceptable for your supply chain and application specifications.
