Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 973031 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Matching Criteria:

• Number of Positions: 120
• Pitch: 0.098" (2.50mm)
• Connector Type: Header with Male Pins
• Mounting Type: Through Hole
• Termination Method: Press-Fit
• Contact Finish: Gold

The substitute part TE Connectivity AMP Connectors 6469002-1 satisfies all primary matching criteria. While the substitute exhibits differences in row/column configuration (8 rows × 10 columns versus 12 rows), the total position count of 120 and pitch specification remain identical. The substitute is classified as active product status, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6469002-1 serves as the designated substitute for the obsolete TE Connectivity Erni 973031. Both components maintain ROHS3 compliance and MSL Level 1 classification, ensuring regulatory alignment for current manufacturing standards.

The substitute part transitions from obsolete to active product status, providing assured long-term availability and supply chain continuity. The 6469002-1 is classified as a high-speed connector within the Z-PACK HM-Zd series, offering enhanced electrical performance characteristics including specified current rating (0.700A) and voltage rating (250V).

Physical footprint compatibility is maintained through identical pitch (0.098" / 2.50mm) and total position count (120). The reconfiguration from 12 rows to 8 rows × 10 columns represents a geometric variation that requires PCB layout assessment during implementation. Both components utilize press-fit termination and gold contact finish, supporting equivalent assembly and reliability profiles.

Frequently Asked Questions (FAQ)

Q: Can the 6469002-1 directly replace the 973031 without PCB modification?

A: Physical compatibility depends on PCB footprint design. Both parts maintain 120 positions at 0.098" (2.50mm) pitch and through-hole mounting. However, the row/column configuration differs (12 rows versus 8 rows × 10 columns). PCB layout assessment is required to confirm mounting hole alignment and clearance compatibility.

Q: What is the primary reason for substitution?

A: The 973031 is classified as obsolete product status. The 6469002-1 is an active product offering equivalent electrical and mechanical specifications with assured supply chain availability.

Q: Are there compliance differences between the two parts?

A: Both parts maintain ROHS3 compliance and MSL Level 1 classification. No regulatory compliance gaps exist between the main part and substitute.

Q: What are the key electrical differences?

A: The substitute part provides specified electrical ratings: 0.700A current rating and 250V voltage rating. The main part does not include published electrical specifications. Operating temperature ranges differ slightly: 973031 operates -55°C to 125°C, while 6469002-1 operates -65°C to 105°C.

Q: Does the substitute include additional features?

A: The 6469002-1 is designated as a high-speed connector with contact layout specification (80 single signal, 40 ground). The main part does not include these performance classifications.

Q: What packaging differences exist?

A: The 973031 is supplied in tray packaging, while the 6469002-1 is supplied in tube packaging. Inventory management and handling procedures may require adjustment based on packaging format.
