Substitute Part Grouping Explanation

Substitution eligibility for the 68021WA4PL201 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub, Combo
• Connector type: Plug, Male Pins
• Number of positions: 21 (17 + 4 Power)
• Number of rows: 2
• Shell size and layout: 4 (DC, C) - 21WA4
• Mounting type: Panel Mount
• Termination method: Solder Cup
• Shell material and finish: Steel, Nickel Plated
• Contact finish: Gold
• Contact type: Signal and Power
• Flange feature: Housing/Shell (Unthreaded)
• Dielectric material: Polybutylene Terephthalate (PBT)
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part 680M21WA4PL201 meets all mandatory matching parameters and is classified as active product status, providing a direct functional replacement for the obsolete 68021WA4PL201.

Parameter Comparison

Engineering Selection Recommendations

The 680M21WA4PL201 is the direct substitute for the obsolete 68021WA4PL201. Both connectors maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in panel mount D-Sub applications requiring 21-position combo configuration with solder cup termination.

The substitute part offers the advantage of active product status, ensuring ongoing availability and manufacturing support. Both parts maintain equivalent compliance certifications: ROHS3 Compliant and REACH Unaffected status. The operating temperature range and material flammability rating remain consistent across both parts.

Minor variations exist in contact material composition (brass versus copper alloy) and contact form specification (machined in the substitute), which do not affect functional compatibility within the specified electrical parameters. The substitute part's current rating of 5A (versus 3A in the main part) at signal positions represents an improvement in electrical capacity while maintaining the 20A power position rating.

Frequently Asked Questions (FAQ)

Q: Can the 680M21WA4PL201 be used as a direct replacement for the 68021WA4PL201?

A: Yes. The 680M21WA4PL201 is a direct functional substitute. Both connectors share identical mechanical dimensions, pin configuration (21 positions in 2 rows), shell size (4 DC, C layout), mounting method (panel mount), and termination type (solder cup). Electrical parameters and compliance certifications are equivalent.

Q: What is the difference in current rating between these parts?

A: The main part 68021WA4PL201 is rated at 3A for signal positions and 20A for power positions. The substitute 680M21WA4PL201 is rated at 5A for signal positions and 20A for power positions. The higher signal position rating in the substitute represents improved electrical capacity and does not affect compatibility.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in available documentation. The substitute part 680M21WA4PL201 is supplied in tray packaging. This difference affects only procurement and handling procedures, not connector functionality or performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 68021WA4PL201 and 680M21WA4PL201 are ROHS3 Compliant and REACH Unaffected. Both maintain UL94 V-0 material flammability rating and operate across the identical temperature range of -55°C to 125°C.

Q: What is the difference between brass and copper alloy contact materials?

A: The main part uses brass contacts while the substitute uses copper alloy contacts. Both materials provide equivalent electrical conductivity and corrosion resistance for D-Sub connector applications. The contact material difference does not affect electrical performance or mechanical compatibility.

Q: Why is the main part listed as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The active status of the substitute part 680M21WA4PL201 ensures continued availability for new designs and replacement applications requiring this connector configuration.
