Key Parameters

Substitute Part Grouping Explanation

Substitution of the 73277-101002 is based on the following critical parameters:

• Connector Category & Type: Both rectangular and card edge connectors with receptacle/female configurations are evaluated for functional equivalence
• Position Count & Pitch: The 100-position, 0.031" (0.80mm) pitch specification defines the contact density and spacing requirements
• Mounting Configuration: Surface mount technology with board guide features ensures PCB integration compatibility
• Contact System: Gold-plated contacts for signal integrity and reliability
• Row Configuration: Dual-row arrangement for compact high-density applications

The substitute part 6123215-1 represents a functionally equivalent alternative from TE Connectivity AMP Connectors, offering 150-position capacity with 0.024" (0.60mm) pitch in a dual-row, surface mount configuration with gold-plated contacts.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The 73277-101002 is classified as obsolete. The 6123215-1 from TE Connectivity AMP Connectors is an active product offering equivalent surface mount, dual-row, gold-plated contact architecture with board guide features.

Compliance Considerations: The substitute part 6123215-1 is RoHS compliant, whereas the original 73277-101002 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations or requiring compliance documentation.

Regulatory Classification: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent export control and tariff treatment.

Availability & Supply Chain: The 6123215-1 is currently active in production with documented inventory availability, ensuring long-term supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 6123215-1 directly replace the 73277-101002 in existing designs?

A: Both connectors feature surface mount technology, dual-row configuration, gold-plated contacts, and board guide features. However, the 6123215-1 operates at a finer pitch (0.024" vs. 0.031") and supports higher position density (150 vs. 100 positions). Physical PCB layout compatibility must be verified for your specific application.

Q: What is the significance of the pitch difference between these parts?

A: The 73277-101002 uses 0.031" (0.80mm) pitch, while the 6123215-1 uses 0.024" (0.60mm) pitch. This affects contact spacing, PCB trace routing, and overall connector footprint. Finer pitch enables higher density but requires more precise manufacturing tolerances.

Q: Why is RoHS compliance status different between the parts?

A: The 73277-101002 predates RoHS regulations and is classified as non-compliant. The 6123215-1, as an active product from TE Connectivity, meets current RoHS requirements. For applications requiring RoHS compliance, the substitute part is the appropriate selection.

Q: Are both connectors suitable for the same environmental conditions?

A: Both parts share identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating equivalent performance in standard storage and operating environments without special moisture control requirements.

Q: What packaging format is the substitute part supplied in?

A: The 6123215-1 is supplied in tray packaging, suitable for automated assembly processes and high-volume production environments.
