Key Parameters

Substitute Part Grouping Explanation

The PC-1620(10) qualifies as a direct substitute based on the following matching parameters:

• Manufacturer: Hirose Electric Co Ltd (same manufacturer ensures design compatibility)
• Series: Sumicon 1600 (same connector series)
• Connector Type: Plug (identical function)
• Contact Type: Male Pin (identical contact configuration)
• Number of Positions: 20 (identical pin count)
• Number of Rows: 3 (identical row configuration)
• Mounting Type: Free Hanging (In-Line) (identical mounting method)
• Contact Termination: Crimp (identical termination method)
• Insulation Material: Resin (identical material)
• Features: Flange (identical feature set)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)

The only variation between the main part and substitute is the insulation color (blue versus black), which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PC-1620(10) is the direct equivalent for the obsolete PC-1620. Selection between these parts should be based on the following criteria:

For new designs or long-term production: PC-1620(10) is the preferred choice. This part carries Active product status, ensuring continued manufacturer support and availability. The part is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components in most markets.

For legacy system maintenance: Either part is electrically and mechanically compatible. The PC-1620 remains available in inventory (1052 units) for applications requiring the original blue insulation color. The PC-1620(10) offers superior long-term supply assurance with its Active status and RoHS compliance.

Color consideration: The color difference (blue versus black) is a cosmetic variation only and does not affect connector function, performance, or compatibility. Selection should be based on system documentation requirements or visual identification needs.

Frequently Asked Questions (FAQ)

Q: Can PC-1620(10) be used as a direct replacement for PC-1620?

A: Yes. Both parts are identical in all electrical and mechanical parameters: 20-position plug housing, male pin contacts, 3-row configuration, crimp termination, free-hanging in-line mounting, and resin insulation with flange. The only difference is insulation color (black versus blue), which does not affect compatibility.

Q: Why is PC-1620 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. PC-1620(10) is the active equivalent and is the recommended choice for new applications and ongoing procurement.

Q: Does the color difference affect electrical performance?

A: No. Insulation color is a cosmetic specification and does not impact electrical characteristics, signal integrity, or mechanical fit.

Q: Is PC-1620(10) RoHS compliant?

A: Yes. PC-1620(10) is RoHS Compliant. RoHS status for the original PC-1620 is not specified in available documentation.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are contacts included with these housings?

A: No. Both PC-1620 and PC-1620(10) are housings only. Contacts must be sourced separately and crimped into the housing.

Q: What is the difference between bulk and standard packaging?

A: PC-1620(10) is supplied in Bulk packaging. Packaging format does not affect connector function or compatibility; it relates only to order quantity and handling logistics.
