Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support: The 646356-1 remains suitable for existing installations where component replacement is not required. Current inventory of 2100 pieces supports ongoing maintenance operations for established systems.

For New Procurement and Design Updates: The 5646356-1 is the designated substitute part for all new applications and system redesigns. This part carries Active product status, ensuring long-term availability and supply chain continuity. The 5646356-1 is classified under the Z-PACK series and provides identical electrical and mechanical compatibility with enhanced documentation of electrical specifications (voltage rating, current rating, and operating temperature range).

Compliance Considerations: Both parts meet RoHS requirements and carry EAR99 ECCN classification. The 5646356-1 carries ROHS3 compliance, representing the current regulatory standard. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.

Supply Chain Strategy: Organizations should transition to the 5646356-1 for all new designs and procurement activities. The Active status of the substitute part ensures availability through standard distribution channels and direct manufacturer supply.

Frequently Asked Questions (FAQ)

Q: Can the 5646356-1 be used as a direct replacement for the 646356-1 in existing assemblies?

A: Yes. Both parts share identical pitch (2.00mm), connector type (Header with Male Pins), mounting method (Through Hole), and position count (220). The electrical and mechanical parameters are compatible for direct substitution in existing circuit board designs.

Q: What is the significance of the position designation "220 (176 + 44 Ground)" in the 5646356-1?

A: This designation indicates the position breakdown within the 220-position connector: 176 signal positions and 44 dedicated ground positions. The total position count of 220 remains equivalent to the main part specification.

Q: Are there any differences in row configuration between the two parts?

A: The main part specifies 10 rows, while the substitute specifies 8 + 2 rows. This represents an equivalent configuration where the 2 additional rows serve as ground or dedicated functional rows. The overall connector footprint and position arrangement remain compatible.

Q: Why is the 5646356-1 preferred for new designs despite the 646356-1 still having inventory?

A: The 5646356-1 carries Active product status, ensuring ongoing manufacturer support, documentation updates, and supply chain availability. The 646356-1 is Obsolete, meaning production has ceased and future availability cannot be guaranteed. New designs should utilize Active parts to avoid future obsolescence issues.

Q: What packaging format is used for the 5646356-1?

A: The 5646356-1 is supplied in Tube packaging, which is standard for high-position-count connectors and provides protection during storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. The 646356-1 is RoHS Compliant, and the 5646356-1 is ROHS3 Compliant. Both meet current environmental and regulatory requirements for electronic components.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special dry-pack storage or baking procedures prior to assembly.
